X= base

Area= 1/2(base)(height)
24=1/2(b)(4)
24=(4*1*b)/2
24=4b/2
Divide 2 into 4
24=2b
Divide both sides by 2
12=b

base= x= 12 units

Hope this helps! :)

The monthly cost of driving a car depends on the number of miles driven. Lynn found that in May it cost her $420 to drive 500 mi
djyliett [7]

Answer:

C(d) = \frac{1}{5}d + 320

Step-by-step explanation:

Given

d \to miles

C \to cost

So:

(d_1,C_1) = (500,420) --- May

(d_2,C_2) = (620,444) --- June

Required

Express as a function

Start by calculating the slope (m)

m = \frac{\triangle C}{\triangle d}

m = \frac{444-420}{620-500}

m = \frac{24}{120}

Simplify

m = \frac{1}{5}

The equation is:

C(d) = m(d - d_1) +C_1

C(d) = \frac{1}{5}(d - 500) +420

C(d) = \frac{1}{5}d - 100 +420

Take LCM

C(d) = \frac{1}{5}d + 320

What type of triangle is a 9.9 cm, 9 cm, 0.99 cm
Masja [62]
It would be an isosceles triangle. Since there are two sides of the triangle that are congruent, it would be isosceles.

Isosceles has two congruent sides, scalene has none, and equilateral has three.  

(A good tip to do is this: count the number of syllables in each word. Then take away two. That's how many sides that triangle has.)

Ex: i-so-sce-les has four syllables. Take away two, you get two. Therefore, an isosceles triangle has two congruent sides.

Hope that helps!

A garden is 30 feet long. a row of beans is planted every 15 inches. how many rows of beans are in the garden? a. 20 rows b. 24
Anettt [7]

Answer:

b) 24 rows

Step-by-step explanation:

12 inches = 1 foot

Since we are doing 30 feet, multiply 12 by 30

12 · 30 = 360 inches

Then, divide the total length (360 inches) by the spacing size (15 inches)

360 ÷ 15 = 24 rows total
