What is the area of this composite figure?
I WILL GIVE BRAINLIEST
A figure is comprised of 2 rectangles. The first rectangle has a length of 10.5 centimeters and width of 15.5 centimeters. The second rectangle has a length of 18 centimeters and width of 11.5 centimeters.
135 centimeters squared
207 centimeters squared
249 centimeters squared
279 centimeters squared
Answer:
249 centimeters squared
Step-by-step Explanation:
The area of the rectangle: l x w, where l is the length and w is the width.
= 15.5 x 18
= 279
Area of the smaller rectangle: l x w, where l is the length and w is the width.
= 4 x 7.5
= 30
We do not need this 30.
Area of the shaded region:
= 279 - 30
= 249 cm²

What is Isosceles Triangle ?An isosceles triangle has two equal sides regardless of the direction the apex (or peak) of the triangle points. Some useful information regarding isosceles triangles is as follows:
It has two parallel sides.It has two equal angles, which are known as the basis angles.A right isosceles triangle is one in which the third angle is 90 degrees.We have a Triangle.
Then, using Isosceles Triangle Theorem
Angles opposite an isosceles triangle's equal sides are also equal.
According to the isosceles triangle theorem, if two sides of a triangle are congruent, then the angles opposite the congruent sides are likewise congruent.
So, x= 42 degree.

HELP PLEASE WORTH A LOT OF POINTSSSSSSSSS!! SHOW YOUR WORK PLEASEEEEE!!!!!!!!!!
Answer:
Step-by-step explanation:
Tan 70 = 16/x
x = 16/tan70
x = 5.824 to the nearest thousandth
tan 41 = 16 / (x + y)
tan 41 = 16 /(5.8235 + y)
tan41(5.8235 + y) = 16
5.8235 + y = 16/ tan41
y = (16/ tan41) - 5.8235
y = 12.582 to the nearest thousandth

Answer:
94 Wins
Step-by-step explanation:
Here we need to find the mean, to do this we add up all the values then divide the sum by how many values we started out with.
97 + 103 + 92 + 95 + 84 = 471
471 / 5 = 94.2
since we got a decimal we can round to find an exact number; since the decimal is under .5 we will round down, 94
So 94 wins would be the correct answer. Hope this helped!

Factorise 3(3x-y)-(y-3x)
Answer:
4(3x-y)
Step-by-step explanation:
Given:
[tex]\displaystyle \large{3(3x-y)-(y-3x)}[/tex]
To factor this kind of expression, first, find the common factor.
[tex]\displaystyle \large{3(3x-y)-(-3x+y)}\\\displaystyle \large{3(3x-y)+(3x-y)}[/tex]
Notice that in the expression, we have both same (3x-y). Therefore, (3x-y) is our factor.
Let u = 3x-y
[tex]\displaystyle \large{3u+u}\\\displaystyle \large{4u}[/tex]
Change u back to 3x-y:
[tex]\displaystyle \large{4(3x-y)}[/tex]
Therefore, the factored expression is 4(3x-y).

solve for y 3x+6y=30
Answer:
the answer= y=5−x/2
Answer: [tex]y=-\frac{1}{2} x+5[/tex]
Step-by-step explanation:
We need to isolate y by itself
Step 1) Subtract 3x from both sides
[tex]3x+6y=30\\3x-3x+6y=30-3x\\6y=30-3x[/tex]
Step 2) Divide both sides by 6 to isolate y
[tex]6y=30-3x\\\frac{6y}{6} =\frac{30}{6}-\frac{3x}{6} \\y=5-\frac{1}{2}x[/tex]

Step-by-step explanation:
sin theta = opposite/hypotenuse = b/c
cos theta = adjacent/hypotenuse = a/c
tan theta= opposite/adjacent = b/a
For the rest, you just flip it:
csc theta = c/b

Answer:
9
Step-by-step explanation:
Since Area = L × W
Thus,
Area = (x + 2)(2x - 5) = 56
x^2 +4x - 5x - 10 = 56
x^2 - x - 10 = 56
x^2 - x - 66
Using the quadratic formula:
a = 1
b = - 1
c = - 66
Solving:
[tex]\frac{x = (-b) +/- sqrt(b^2 - 4ac)}{2a}[/tex]

Determine the solution(s) to f(x) = g(x) given the graph below.
Answer:
(-1,-3) and (1,-1)
Sometimes you give the solutions as just the x.
x = -1 and x = 1
Step-by-step explanation:
The two curvy pieces are f(x) and the straight line is g(x). The solutions are where the two graphs intersect. There are two points where this happens: (-1,-3) and (1,-1).
Sometimes your teacher, the text or the course just wants you to give the answer as the x where it happens. The graphs intersects where x=-1 and x=1
Solve the system of equations y = 2x^2 + x – 6 and y = 4
Step-by-step explanation:
Substitute y = 4 into the first equation:
[tex]4=2x^2+x-6[/tex]
Subtract 4 from both sides:
[tex]2x^2+x-10=0[/tex]
We can factor in order to find values of x.
Factor the equation:
[tex]2x^2+x-10=0[/tex]
Factors of 10 we'll use:
5 and 2.
[tex](2x+5)(x-2)=0[/tex]
Set the parentheses equal to 0 then find the values of x:

[tex](x-2)=0[/tex]
[tex]x=2[/tex]

A can of diced tomatoes has a height of 11.5 cm and a diameter of 10 cm.
What is the volume of the can? Use 3.14 for i.
DO NOT round your answer.
A cubic cm
Answer:
10 cm
Step-by-step explanation:
the can is shaped like a cylinder
first step is to find the radius and then multiply the figure by 2
volume of a cylinder = nr^2h
n = 22/7
r = radius
903 = 11.5 x r^2 x 3.14
r^2 = 903 / (3.14 x 11.5)
r = 5 cm
diameter = 10cm
if your catering people and its $80 for 6-8 people how much would it be to cater 128 people
Answer:
Your answer(s) is $1,706.67, $1,462.86, or $1,280
Step-by-step explanation:
This really varies based on whether you take $80 as equal to 6 people, 7 people, or 8 people.
I'll list all three explanations and you can choose one.
6 people: 1,706.67 (rounded to nearest cent)
128 ÷ 6 = 21.33333333
21.33333333 × 80 = 1,706.67
7 people: 1,462.86 (rounded to nearest cent)
128 ÷ 7 = 18.28571428571429
18.28571428571429 × 80 = 1,462.86
8 people:
128 ÷ 8 = 16
16 × 80 = 1,280
