Answer:
=Barlow by 181 boys
Step-by-step explanation:
lets calculate the no of boys in Barlow
=4/9×873=388
388 boys
in Willow school
to bet no of boys
3/3-2/3=1/3
1/3×620=207(in a calculator it will give you decimals so i rounded of to the nearest whole no.)
388-207=181
Answer: 3.5
Step-by-step explanation:
Given: Dimensions of larger prism = length of 4.2 cm, a width of 5.8 cm, and a height of 9.6 cm.
Dimensions of smaller prism = length of 14.7 cm, a width of 20.3 cm, and a height of 33.6 cm.
Scale factor = 
Since, smaller figure is the original figure and the bigger one is the image.
So, scale factor = 
[Taking lengths
Hence, the factor to produce the corresponding dimensions of the larger prism = 3.5
Answer:
Steps 3 and 4 are incorrect because
(a) An incorrect value for slope was obtained in step 3.
(b) The incorrect value for the slope was used in step 4.
Explanation:
Let us evaluate Talia's steps.
Step 1: Select (2, 5) as a point on the line.
CORRECT
Step 2: Select another point (1, 3) on the line.
CORRECT
Step 3: Count units to the right and count units up, to determine the slope.
Units right = 2 - 1 = 1
Units up = 5 - 3 = 2
Slope = (Units up)/(Units right) = 2/1 = 2
INCORRECT because Talia did not obtain a slope of 2.
Step 4: Substitute obtained values in the point-slope form.
(y - y1) = m(x - x1). If we select the point (1, 3), then
y - 2 = 2(x - 1).
Talia's equation is INCORRECT because she used an incorrect value
for the slope.
Hello,
Diagonals of a rectangle must have the same measure.
You don't need to know the dimension of the diagonal but only if they are equals.
(√(90²+48²)=102 (yd))
