Problem: How many cubic yards of concrete must be ordered to pour the section
timama [110]

Answer:

0.9 yd³

Step-by-step explanation:

Information given:

Length = 18 ft

Width = 1.5 ft

Height = 1 ft

What to find/do:

First, convert the measurement from feet to yards. (3 ft = 1 yard)

Length = 18 ft = 6 yd

Width = 1.5 ft = 0.5 yd

Height = 1 ft = 0.3 yd

Next, find the volume of the shape given. The volume would give us the amount of concrete to use in yards.

Formula for volume = L*W*H

Plug in the values into the formula

V = 6*0.5*0.3 = 0.9 yd³

0.9 cubic yard of concrete must be ordered to pour on the given section.

Area of the volume

Which is the solution set of the inequality<br> -15y+9&lt;-36
liraira [26]

Answer:

-15y+93\:\\ \:\mathrm{Interval\:Notation:}&\:\left(3,\:\infty \:\right)\end{bmatrix}

Therefore, the first choice is correct.

The graph of the inequality is also attached below.

Step-by-step explanation:

Considering the inequality

-15y+9

solving

-15y+9

\mathrm{Subtract\:}9\mathrm{\:from\:both\:sides}

-15y+9-9

-15y

\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}

\left(-15y\right)\left(-1\right)>\left(-45\right)\left(-1\right)

15y>45

\mathrm{Divide\:both\:sides\:by\:}15

\frac{15y}{15}>\frac{45}{15}

y>3

In other words,

-15y+93\:\\ \:\mathrm{Interval\:Notation:}&\:\left(3,\:\infty \:\right)\end{bmatrix}

Therefore, the first choice is correct.

The graph of the inequality is also attached below.

Can someone answer this question i am having an issue to how to figure it out
blondinia [14]

Answer:

explanation below

Step-by-step explanation:

f(x) = 3x + 2

f(8) : replace x with 8    f(8) = 3 * 8 + 2 = 26

g(x) = 5x

g(a+2) : replace x with a+2    g(a+2) = 5 (a+2) or 5a + 10
