Answer:
1376x-736
Step-by-step explanation:
Take 32 and multiply it by 43. By multiplying vertically, distribute the multiplication of 3 (from 43) times both the 2 and 3 of 32 (right to left)
3 x 2=6; 3 x 3=9:
32
x
43
--------
96
Then, distribute the multiplication of 4 (from 43) times both the 2 and 3 of 32 (right to left) and leave a zero under the last number of your previous answer while moving the distribution of numbers forward.
4 x 2=8; 4 x 3=12
32
x
43
--------
96
+
1280 <----(this is the zero you must leave under your previous set)
After distributing each number of 43 to each number of 32 while multiplying, add your answers together vertically from right to left and bring down the x:
96
+
1280
----------
1376x
Now do the same for 32 x -23 after learning vertical multiplication to get -736
Your final answer put together is 1376x-736

How many diners ordered churros last week?
Answer:
900
Step-by-step explanation:
4F + F =1125
5F = 1125
F=225
C=4F
C=4(225)=900
900 + 225=1125
What is the value of W?
Answer:
Step-by-step explanation:
Let angle A = w - 15 degree , angle B = -w + 1 degree and angle X = w + 34 degrees then:
We know that the exterior angle of a triangle is equal to the sum of two interior opposite angles.
therefore, w + 34 = w - 15 + (-w +1)
w + 34 = w - 15 - w + 1
w = -15 - 34 = - 49 degrees
since angle cannot be negative
therefore w = 49 degrees

Answer:
x = 11.2
Step-by-step explanation:
We know that the second triangle is just a smaller scale of the bigger triangle.
So, first, we take
28 divided by 25 = 1.12
Then we take
10 times 1.12 = 11.2
So, x = 11.2
Need some help with these trigonometry questions
Answer: 11, 23, 166
Step-by-step explanation:
Hiya! From the drawings, I'm assuming all of the triangles are right-angled triangles. If they aren't though, tell me and I'll tell you how to solve them.
Anyways, assuming they are right angled-triangles, you can use Pythagoras' Theorem (aka a² + b² = c²)
c is the hypotenuse or the side opposite the right angle.
a and b are just the other two sides (doesn't really matter which is which)
Question 7:
c² = a² + b²
12² = a² + 5²
144 = a² + 25
144 - 25 = a²
119 = a²
a = 10.908712114635714411502154487373
(To the nearest whole number: 11)
Question 8:
c² = a² + b²
24² = 7² + b²
576 = 49 + b²
576 - 49 = b²
527 = b²
b = 22.956480566497992703585747092065
(To the nearest whole number: 23)
Question 9:
c² = a² + b²
c² = 90² + 140²
c² = 8,100 + 19,600
c² = 27,700
c = 166.43316977093238068928214785346
(To the nearest whole number: 166)

The height of an equilateral triangular based prism is 30 cm. If the area of one base of the prism is 16√3 cm², find the area of the rectangular surfaces of the prism.
The area of one base of the triangular prism is given as 16√3 square cm, and since the base is equilateral, the sides of the triangle are of equal length.
The formula to calculate the area of an equilateral triangle is (sqrt(3)/4) * s^2 where s is the length of a side of the triangle.
So, plugging in the given area of base, 16√3, we can find the length of a side of the equilateral triangle, s.
16√3 = (sqrt(3)/4) * s^2
s = (4*16√3)/sqrt(3) = 16√3 cm
Now we can use the height of the prism, which is given as 30 cm, to find the area of the rectangular surface.
Area of the rectangular surface = 2 * base area * height = 2 * 16√3 * 30 cm²
This simplifies to:
960√3 cm²
So the total area of the rectangular surface of the prism is 960√3 square cm.

Which graph represents-3x - 4y ≤ 2?
Answer:
B
Step-by-step explanation:
What is the midpoint of the x-intercepts?
The midpoint of the x-intercept is (0,0).
By looking at the equation, we may determine the y-intercept when the equation is expressed in the slope-intercept form (y=mx+b). The y-intercept is the value of b. This is due to the fact that the occurs when the x value is 0. Y = B when x = 0, since mx y-intercept = 0 at this point.
We set y = 0 and solve the equation for x to determine the x-intercept. This is due to the fact that the line crosses the x-axis at y=0. If an equation is not in the form y = mx + b, we can still solve for the intercepts by substituting 0 where necessary and then solving for the final variable.
The formula for the x-intercept is y = 0: The x-intercept(s) can be determined by factoring or by employing the quadratic formula because ax2 + bx + c=0.

The equivalent trigonometric identity to cot²θ + 1 is cot²θsec²θ
What are trigonometric identities?Trigonometric identities are equations which contain the trigonometric ratios.
How to show the equivalent identity of cot²θ + 1?Since we have the trigonometric identity cot²θ + 1,we need to find its equivalent expression.
So, we proceed as follows
Since cot²θ + 1 = 1/tan²θ + 1 (since cot²θ = 1/tan²θ)
Now taking the L.C.M, we have that
1/tan²θ + 1 = (1 + tan²θ)/tan²θ
We know that the trigonometric identity 1 + tan²θ = sec²θ
So, substituting this into the equation, we have that
(1 + tan²θ)/tan²θ = sec²θ/tan²θ
Since cot²θ = 1/tan²θ, substituting the values of the variables into the equation, we have that
sec²θ/tan²θ = cot²θsec²θ
So, cot²θ + 1 = cot²θsec²θ

Find the equation of the line that passes through (1,2) and is perpendicular to y=2x+3. Leave your answer in the form y=mx+c
Answer:
y = -1/2x + 5/2
Step-by-step explanation:
If two lines are perpendicular to each other, they have opposite slopes.
The first line is y = 2x + 3. Its slope is 2. A line perpendicular to this one will have a slope of -1/2.
Plug this value (-1/2) into your standard point-slope equation of y = mx + b.
y = -1/2x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (1, 2). Plug in the x and y values into the x and y of the standard equation.
2 = -1/2(1) + b
To find b, multiply the slope and the input of x (1)
2 = -1/2 + b
Now, add 1/2 to both sides to isolate b.
5/2 = b
Plug this into your standard equation.
y = -1/2x + 5/2
This equation is perpendicular to your given equation (y = 2x + 3) and contains point (1, 2)

At a banquet hall there are 25 tables that seat 4 people and 30 tables that seat 6 people. There are no other tables in the banquet hall. What is the ratio of the number of tables that seat 4 people to the total number of tables in the banquet hall?
Answer:
1:11
Step-by-step explanation:
We know
There are 25 tables that seat 4 people
First, we find the total number of tables by taking
25 + 30 = 55 tables
Then we find the ratio of tables that seat 4 people to the total number of tables by
5 / 55 = 1/11 = 1:11
So, the ratio is 1:11
The area of a square garden is 900 square feet. What is the length of one side of the garden? A 450 ft C 225 ft B 300 ft D 30 ft
Answer:
[tex]\boxed {\boxed {\sf D. \ 30 \ feet}}[/tex]
Step-by-step explanation:
The area of a square is found by multiplying the base and the height, but since all the sides are equal, it is equal to multiplying a side by another side.
[tex]a=s*s[/tex]
[tex]a=s^2[/tex]
We know the square garden has an area of 900 square feet. We can substitute this value in for a.
[tex]900 \ ft^2=s^2[/tex]
Since we are solving for the side, we have to isolate the variable s. It is being squared. The inverse of a square is the square root, so we take the square root of both sides.
[tex]\sqrt {900 \ ft^2}= \sqrt{s^2}[/tex]
[tex]\sqrt {900 \ ft^2}=s \\[/tex]
[tex]30 \ ft=s[/tex]
One side of the garden is equal to 30 feet and choice D is correct.

A 20-gallon bathtub is to be filled with water that is exactly 100°F. The hot water supply is 175°F and the cold water supply is 20°F. When mixed, the temperature will be a weighted average based on the amount of each water source in the mix. How much of each should be used to fill the tub as specified?
320/31 gallons of hot water and 300/31 gallons of cold water are needed.
Here we are required to fill a 20-gallon bathtub and the water should be precisely 100° F.
It is given that hot water has a temperature of 175° F and cold water has a temperature of 20° F.
Let the amount of hot water used be x gallons.
Let the amount of cold water used be y gallons.
Since the bathtub has a capacity of 20 gallons,
x + y = 20 [1]
or, y = 20 - x [2]
The temperature after the water is mixed will be a weighted average of the temperature and amt of water used.
Hence we get,
(175x + 20y) / (x + y) = 100
from equation [1] we get
175x + 20y = 2000 [3]
from equations [2] and [3] we get
155x - 400 = 2000
or, x = 1600/155 = 320/31 [4]
Similarly,
y = 20 - 320/31
= 300/31
Hence 320/31 gallons of hot water and 300/31 gallons of cold water are needed.

Every tread of a staircase is 8 in. deep, and every riser is 6 in. high. How would you find the angle the staircase makes with the floor? Explain.
Answer:
36.9°
Step-by-step explanation:
You want to know the pitch angle of a staircase with a riser height of 6 inches and a tread depth of 8 inches.
TangentThe tangent of an angle is the ratio of the side opposite to the side adjacent:
Tan = Opposite/Adjacent
ApplicationThe tangent of the staircase angle to the floor will be the ratio of the riser height to the tread depth:
tan(α) = (6 in)/(8 in) = 3/4
The angle is found using the inverse tangent function.
α = arctan(3/4) ≈ 36.9°
__
Additional comment
You need to be a little bit careful here. Different authors define "tread depth" differently. For the purpose of this question, it must be defined as the horizontal distance between corresponding points on adjacent treads, as shown in the attached illustration.
Some authors define tread depth as the distance from the nosing to the riser. If that definition is used, the "run" of the step will be the tread depth less the nosing depth. The pitch angle will be the arctangent of the ratio of riser height to "run".
The tread depth of 8 inches is a little too narrow to be in compliance with some building codes. A more usual minimum is about 10 inches with a riser height of 7 1/2 inches.
