Notice that we can calculate the area of the square and the rectangle separately to get the following:

$\begin{gathered} A_1=3\cdot3=9in^2 \\ A_2=9\cdot2=18in^2 \\ \Rightarrow A=A_1+A_2=9+18=27in^2 \end{gathered}$

therefore, the total area is 27 in^2

the coordinates of point t are (0,2). the midpoint of st is (1,-6) find the coordinates of point s.

sasho [114]

Question

the coordinates of point t are (0,2). the midpoint of st is (1,-6) find the coordinates of point s.

Answer:

(10,-14)

Step-by-step explanation:

0 + x

--------- = 5 Multiply both sides by 2 ----> 0 + x = 10 or x = 10

2 + y

-------- = -8 Multiply both sides by 2 ----> 2 + y = -16 or y = -14

Therefore, the coordinates of point S should be at (10,-14)

Diego has $11 and begins saving $5 each week toward buying a new phone. At the same time that Diego begins saving, Lin has $60 a

Nata [24]

Answer:

Let x represents the week and y represents the amount of money.

As per the given statement:

Diego has $11 and begins $5 each week toward buying a new phone.

⇒ ......[1]

It is also given that Lin $60 and begins spending $2 per week.

⇒ ....[2]

when they have the same amount.

equate [1] and [2] we get;

Add both sides 2x we get;

Subtract 11 from both sides we get;

Divide both sides by 7 we get;

x = 7

Substitute the value of x = 7 in [1] we have;

Therefore, at x= 7 week they have the same amount of money and they have the amount at that time, $ 46

An engineer is designing a large steel pad to be installed on the deck of an aircraft carrier. Its total volume will be 18 yd^3.

Shtirlitz [24]

Answer:

The cost of the material for the full-sized pad is;

d) 222,750.00

Step-by-step explanation:

The parameters of the steel pad and the scale model are;

The volume of the deck = 18 yd³

The dimensions of the model of the same material = 6 feet by 4.5 feet and 4.5 inches thick

The weight of the sample, m₂ = 75 lbs

The cost of the steel, P = $55/lb

The dimensions of the sample in yards are;

6 feet = 2 yards, 4.5 feet = 1.5 yards, and 4 inches = 0. $\overline 1$ yards

The volume of the sample, V₂ = 2 yd. × 1.5 yd. × 0. $\overline 1$ yd. = (1/3) yd.³

The density of the sample material, ρ = m₂/V₂

∴ The density of the sample material, ρ = 75 lbs/((1/3)yd.³) = 225 lbs/yd³

Therefore, the density of the material of the pad, ρ = 225 lbs/yd³

The mass of the steel pad, m₁ = ρ × V₁

∴ The mass of the steel pad, m₁ = 225 lbs/yd³ × 18 yd³ = 4,050 lbs

The cost of the material for the full-sized steel pad, C = m₁ × P

∴ C = 4,050 lbs × $55/lb = $222,750
