Answer:
2 kg
Step-by-step explanation:
5 - 3 = 2
Hey there!
First, read the the problem again and look for any clues. "Have left" is a phrase that would be used for subtraction. So, 5 kg - 3kg = 2 kg.

write the expression as the sine or cosine of an angle.
sin 3x cos x - cos 3x sin x
In other words, you'll type "sin" without quotes in the green box.
Also, you'll type "2" in the gray box, which also won't have quotes.
===========================================================
Explanation:
We'll use the first hint. Note the pattern of sin cos +- cos sin which matches (somewhat) with the original expression.
Specifically, we'll use this identity
sin(A - B) = sin(A)cos(B) - cos(A)sin(B)
In this case, A = 3x and B = x
So,
sin(A - B) = sin(A)cos(B) - cos(A)sin(B)
sin(A)cos(B) - cos(A)sin(B) = sin(A - B)
sin(3x)cos(x) - cos(3x)sin(x) = sin(3x - x)
sin(3x)cos(x) - cos(3x)sin(x) = sin(2x)

17. Negative numbers are closed under addition.
True or false
===========================================================
Explanation:
Picking any two negative numbers, then adding them, will result in some other negative number. This is why the set of negative numbers is closed under addition.
Examples:
-2 + (-3) = -5
-10 + (-14) = -24
-7 + (-9) = -16
This is because when you add two negatives, you're adding their positive counterparts. Going to the first example above, we would say 2+3 = 5 and then just make everything negative. There's no way to add two negative numbers, and get a positive result (and we can't get 0 either).
You can think of it in terms of money and debt. The -2 represents being 2 dollars in debt. Then adding on 3 more dollars of debt leads ultimately to 5 dollars overall in debt.

-5/9 is rational, and its none of the other choices (integer, whole, irrational). So this value goes in the "rational" rectangle, and outside any other region.
The number [tex]-\sqrt{100}[/tex] turns into -10 after simplification. We see that this number is both rational and an integer. The best place for it is inside the "integer" circle. Note how this circle is entirely in the "rational" rectangle. We do not place it in the "whole number" circle because whole numbers are not negative.
The number [tex]\pi[/tex] is irrational since its decimal expansion goes on forever without any known pattern.
The number [tex]\sqrt{25}[/tex] simplifies to 5. This goes in the "whole number" circle.

Slove 3(t-3)=5(2t-1)
Answer:
t = 7/-4 OR -1 3/4
Step-by-step explanation:
3(t - 3) = 5(2t - 1)
3t - 9 = 10t - 5
(3t - 3t) - 9 = (10t - 3t) - 5
-9 = 7t - 5
-9 + 5 = 7t (- 5 + 5)
-4 = 7t
-4/-4 = 7t/-4
t = 7/-4 OR -1 3/4

Answer:
∠1 = 5 degrees
∠2 = 85 degrees
Step-by-step explanation:
if we add ∠1 and ∠2 that will be 90 degrees (as it is straight angle and its already given in the picture)
( x - 12) + 5x = 90
6x -12 = 90
6x = 90 + 12
6x = 102
x = 102/6
x = 17
Put 17 in both the angles instead of x
∠1 = ( x-12)
= ( 17 - 12)
= 5
∠2 = 5x
= 5 (17)
= 85
now you can even Cross-check
5 + 85
= 90 degrees

A car uses 8 litres of gasoline to travel 160 km. How much gasoline will the car use to travel 400 km?
Answer:
20 liters of gasoline
Step-by-step explanation:
Create a proportion where x is the amount of gasoline needed to travel 400 km:
[tex]\frac{8}{160}[/tex] = [tex]\frac{x}{400}[/tex]
Cross multiply and solve for x:
160x = 3200
x = 20
So, the car will use 20 liters of gasoline to travel 400 km.
Answer:
The car will use 20 liters of gas
Step-by-step explanation:
160KM/8L = 20KM per liter
400/20 = 20

PLZZ ANSWER
"You are growing like a weed!” D’rek's grandmother said to him when she saw him for the
first time in a year. If D’rek grew 8 inches over the last year, and an average dandelion (a
common weed) grows 0.1 inches in one day, is D’rek growing like a weed? Justify your
answer.
growth rate:
[tex]=\frac{8}{365}[/tex]Derek is not growing like a weed because the weed grows at 0.1 inch per day, while he grows at a rate of 0.022 inch per day.
The number of days in a year = 365
The question says that D'rek grew at the rate of 8 inches in the last year'
D'reks growth rate:
[tex]=\frac{8}{365}[/tex]
= 0.022 inch per day
From the calculation above, Derek is growing at the rate of 0.022 inch per day. But the question says that the weed grows at the rate of 0.1 inch per day
In conclusion, Derek is not growing like a weed, his growth rate differs from that of the weed.

Answer:
25.04
Step-by-step explanation:
26.12-1.08
=25.04
Answer:
25.04
Step-by-step explanation:
For this problem we have to use subtraction
If Sonya finished the dash is 26.12 seconds and Gladys finished it 1.08 seconds faster, we have so subtract 26.12 by 1.08 to get her time
So we get 25.04

Write the equation of the line in fully simplified slope-intercept form.
Answer:
[tex]y=-6x+2[/tex]
Step-by-step explanation:
Hi there!
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x=0)
1) Determine the slope (m)
[tex]m=\displaystyle \frac{y_2-y_1}{x_2-x_1}[/tex] where two points that fall on the line are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Given the graph, we determine which points we could use. For example, we could use the two points [tex](0,2)[/tex] and [tex](1,-4)[/tex]:
[tex]m=\displaystyle \frac{-4-2}{1-0}\\\\m=\displaystyle \frac{-6}{1}\\\\m=-6[/tex]
Therefore, the slope of the line is -6. Plug this into [tex]y=mx+b[/tex]:
[tex]y=-6x+b[/tex]
2) Determine the y-intercept (b)
Recall that the y-intercept occurs when x=0. Given the point (0,2), we know that the y-intercept is 2. Plug this into [tex]y=-6x+b[/tex]:
[tex]y=-6x+2[/tex]

An airplane is coming in for a landing and the pilot knows she is 5473 m above the ground and she also knows that Angle of depression from the plane to the landing strip is 58º. How far is the plane from the landing strip?
Answer:
3420 m
Step-by-step explanation:
when we say distance, we mean ground distance, right ? not air distance.
so, essentially, the angle from the straight line the plane could be going at that moment down to the touch down point on the landing strip is 58 degrees.
that means the angle of elevation (between the line to the touch down point and the height "line" of the airplane) is 90-58 = 32 degrees
the height of the airplane (= distance from ground) is 5473 m.
now, we also know that the angle between height and the ground connection to the touch down point is 90 degrees (as height is always meshed straight up/down).
so, we know even the third angle (at the touch down point between ground and the line to the airplane)
= 180 - 90 - 32 = 58 degrees.
if we imagine now a circle being drawn with the touch down point being center and going through the right- angle corner point on the ground right under the airplane, we see that the ground distance from that corner to the landing strip is the radius of that circle.
therefore, the height is tan() × r of the angle at the touch down point.
5473 = tan(58) × r
r = 5473 / tan(58) = 3420 m
a right triangle has a non hypotenuse side length of 45" and the hypotenuse measures 53". What is the length of the other non-hypotenuse side?
Answer:
28"
Step-by-step explanation:
the length of the other non-hypotenuse side =
√(53² - 45²) =√(2809-2025) =√784 = 28"
Using Pythagorean theorem
[tex]\\ \rm\longmapsto P^2=H^2-B^2[/tex]
[tex]\\ \rm\longmapsto P^2=53^2-45^2[/tex]
[tex]\\ \rm\longmapsto P^2=2809-2025[/tex]
[tex]\\ \rm\longmapsto P^2=784[/tex]
[tex]\\ \rm\longmapsto P=\sqrt{784}[/tex]
[tex]\\ \rm\longmapsto P=28[/tex]
