Answer:

210 yd³

Step-by-step explanation:

Volume of a triangular prism

= the area of a triangular base × the height

The area of the base

= (10×7)÷2

= 35 yd²

The volume of the prism

= 35 × 6

= <u>210 yd³</u>

A triangle has an area of 36 square feet. If the height of the triangle is 6 more feet than its base, what is its height and bas

andriy [413]

If b is the base then the height h=b+6. As we have S=bh/2 then
36=b(b+6)/2;
b²+6b-72=0;
D/4=3²+72=81
b₁=-3-9=-12
b₂=-3+9=6.
The base is always positive so b=6, h=6+6=12.
Answer: base=6 ft, height=12 ft.

Some girls in a Girl Scout troop are pairing up with some boys in a Boy Scout troop to practice square dancing. Two-thirds of th

Natalka [10]

Answer:

Fraction of the scouts are square dancing is $\frac{19}{30}$ .

Step-by-step explanation:

Each pair is one Girl Scout and one Boy Scout.

So, to the final fraction ( of the pairs) we are going to get 1/2 from the fraction of girls and 1/2 from the fraction of boys.

Girls= $\frac{2}{3} *\frac{1}{2} =\frac{2}{6}$

Boys= $\frac{3}{5} *\frac{1}{2} =\frac{3}{10}$

To get the fraction of the scouts that are square dancing, we have to add the fraction of girls , with the fraction of boys.

= $\frac{2}{6} +\frac{3}{10}$

= $\frac{(2*10) +(6*3)}{6*10} =\\ \frac{20+18}{60}$

= $\frac{38}{60}$

= $\frac{19}{30}$

This means that from 30 scouts , 19 are dancing.

What is the range of the function on the graph

grigory [225]

The answer is the last answer choice:
all the real numbers greater than or equal to -3

The range of a function is all the possible y values of a function. From the function you see on the left side, it shows that the minimum value is at (2, -3) and from there it doesn't go any lower meaning all the values will be higher than -3 for the y value.
