Answer:
D. 118 + s = 764
Step-by-step explanation:
To find the total number of students in all the other grades, if we only know the total number of students in the school and the number of kids in 3rd grade, we need to subtract the kids in 3rd grade from the entire school. This leaves us with 646.
s = 646

Henri built a lantern in the shape of a square pyramid. He wants to cover the entire pyramid with fabric. How much fabric will he need?
A square pyramid with a base of 4 meters by 4 meters and triangular side heights of 3 meters.
16 meters squared
24 meters squared
36 meters squared
40 meters squared
ITS NOT 24
The amount of fabric Henri will need is 40 meters squared
The amount of fabric Henri will require is the surface area of the square pyramid.
What is the surface area of the square spyramid?The surface area of the square pyramid, A = area of square base, A' + area of 4 triangular sides
Area of square baseThe area of the square base is A' = L² where L = length of base = 4 m
So, A = L²
= (4 m)²
= 16 m²
Area of triangular sideThe area of the triangular side is A" = 1/2Lh where
L = length of base = 4 m and h = height of triangle = 3 mSo, A" = 1/2Lh
= 1/2 × 4 m × 3 m
= 1/2 × 12 m²
= 6 m²
Since there are 4 triangular sides, the area of the sides of the pyramid is
4A" = 4 × 6 m²
= 24 m²
Amount of fabric Henri will needSince the amount of fabric Henri will need is the surface area of the square pyramid,
So, The surface area of the square pyramid, A = A' + 4A"
= 16 m² + 24 m²
= 40 m²
So, the amount of fabric Henri will need is 40 meters squared

The equation of the trend line is y = -0.36x + 12.6 use the equation to of the trend line to predict the wind chill for a wind speed of 51 mi/h round your answer to the nearest degree. The wind chill at 51 mi/h
Given:
The equation of the trend line is:
[tex]y=-0.36x+12.6[/tex]
In this equation y represents the wind chill and x represents the wind speed.
To find:
The wind chill at 51 mi/h.
Solution:
We have,
[tex]y=-0.36x+12.6[/tex]
Putting [tex]x=51[/tex], we get
[tex]y=-0.36(51)+12.6[/tex]
[tex]y=-18.36+12.6[/tex]
[tex]y=-5.76[/tex]
Round the answer to the nearest degree.
[tex]y\approx -6^\circ[/tex]
Therefore, the wind chill at wind speed 51 mi/h is -6°.

The Garcia family drives 3/4 of the distance to their grandparent's house
in 3/4 hour.
How many hours will it take
to drive to their grandparent's house at the same rate?
a= 1
b=9/16
c=1 and 7/9
Answer:
a=1
Step-by-step explanation:
because 3/4 hour is 45 minute and it takes 4/4 distance to their grandparents hous ein 4/4 hour so 45÷3=15, 15×4=60 which is 1hour
The Answer is A: 1 hour
Step-by-step explanation:
since they can drive 3/4 the distance in 3/4 hours, they can also drive 1/2 the distance in 1/2 hours and so on. If they want to visit the grandparent's house, they need to drive 4/4 the distance which is equivalent to 1 so it will take 1 hour for them to go to the house at the same rate.

Solve the given proportion 3/4 6/x x=?
Answer:
X=8
Step-by-step explanation:
3×X =6×4
3X=24
X= 24÷3
X= 8
The equivalent value of the proportion is ( 3/4 ) = ( 6/8 ) and x = 8
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the value of A is
( 3/4 ) = ( 6/x )
Multiply by x on both sides , we get
( 3/4 )x = 6
Divide by 3 on both sides , we get
( 1/4 )x = 2
Multiply by 4 on both sides , we get
x = 8
Hence , the proportion is ( 3/4 ) = ( 6/8 )
