Answer:

Step-by-step explanation:

Given

4x + 7y = 14

7y = - 4x + 14

y = $\frac{-4x + 14}{7}$

y = $\frac{-4x}{7} + \frac{14}{7}$

y = $\frac{-4x}{7} + 2$

Hope it helps :)

explanation
1. subtract 4x from both sides
2. divide every term by 7

Given the triangle below, what is m < b, rounded to the nearest tenth?

ahrayia [7]

Option A:

m∠B = 42.1°

Solution:

Given data:

b = 18, c = 15 and m∠C = 34°

Using sine formula:

$$\frac{b}{\sin B}=\frac{c}{\sin C}$

Substitute the given values.

$$\frac{18}{\sin B}=\frac{15}{\sin 34^\circ}$

Do cross multiplication.

$${18} \times {\sin 34^\circ}={15} \times{\sin B}$

Divide by 15 on both sides.

$$\frac{{18} \times {\sin 34^\circ}}{15} =\frac{{15} \times{\sin B}}{15}$

$$\frac{{6} \times0.559}{5} =\sin B$

$$0.6708=\sin B$

$$\sin ^{-1}0.6708= B$

$42.1^\circ =B$

Switch the sides.

m∠B = 42.1°

Option A is the correct answer.

Gavin had 20 minutes to do a three-problem quiz. He spent 9 9/10 minutes on question A and 3 3/5 minutes on question B. How much

dalvyx [7]

Answer:

6 1/2 minutes

Step-by-step explanation:

9 9/10 = 9.9

3 3/5 = 3.6

9.9 + 3.6 = 13.5

13.5 = 13 1/2

20 - 13.5 = 6.5 = 6 1/2

A building in the shape of a square pyramid is being built in Las Vegas. The height of the building will be 309 feet, and a size

finlep [7]

Answer: 51.5 cubic feet.

Step-by-step explanation:

Since, The height of the building will be 309 feet, and a size of the base measures 250 feet.

And, we know that the volume of the square pyramid = $(size of the base)^2\times \frac{height}{3}$

Here, size of the base of the square pyramid = 250 feet.

And, height = 309 feet.

Therefore, the volume of the given square pyramid,

$V=(250)^2\times\frac{309}{3}$

⇒ $V=62500 \times\frac{309}{3}$

⇒ $V= \frac{19312500}{3}$ = 6437500 cubic feet.

Again according to the question,

The scale model that is displayed at a convention is one fiftieth the size of the actual building.

Therefore, Volume of the scale model = the volume of the given square pyramid/125000

= 6437500/125000= 51.5 cubic feet.

Thus, the volume of the scale model is 51.5 cubic feet.
