Answer:
16, 21
Step-by-step explanation:
In this item, we are given with the radius equal to 22 cm.
This measurement of the radius is the hypotenuse of the 30°-60°-90° triangle formed with the half the measurement of the side of the equilateral triangle being opposite to the 60° and equal to the hypotenuse times (1/2)(√3)
If we let s be the side of the triangle then,
s/2 = r(1/2)(√3)
Multiplying the equation by 2,
s = r√3
Substituting,
s = (22 cm)(√3) = 22√3
The area of the equilateral triangle is computed through the equation,
A = (√3 / 4)(s²)
Substituting,
<em> A = (√3 / 4)(22√3)² = 628.7 cm²</em>
Therefore, the answer to this item is the first choice.
F is 4/2. i did the i-ready, hope this helps
Using the dimensions of a reduced rectangle and one given measurement of an original rectangle:
- Set up a proportion using the corresponding parts
- Solve the proportion to find the missing measure
<h3>What is Reduction?</h3>
Reduction is a type of dilation that reduces the size of an original figure to form a new figure that is similar to the original. The corresponding lengths of both figures are therefore proportional.
Assuming the dimensions of the reduced rectangle are 10 cm by 4 cm, and the length of the original rectangle is given as 8 cm, to find the missing measure (x), do the following:
Set up a proportion using the corresponding parts
10/8 = 4/x
Solve the proportion using cross products to find x:
10x = (8)(4)
10x = 32
x = 32/10
x = 3.2 cm
The missing length is 3.2 cm.

Answer:
y=2x+2
Step-by-step explanation:
convert x-2y=7 into slope intercept form
then your new slope is the reciprocal of the original function then substitute
x and y values to find b.
