Answer:

The value of b is 4 cm.

c is the correct option.

Step-by-step explanation:

From the given diagram, we have

$\tan A=\frac{BC}{AC}\\\\\tan A=\frac{a}{b}$

Now, given that

a = 3 cm

tan A = 0.75

On substituting these values, we get

$0.75=\frac{3}{b}$

Cross multiplying, we get

$0.75b=3$

Divide both sides by 0.75

$b=\frac{3}{0.75}\\\\b=4$

The value of b is 4 cm.

c is the correct option.

Answer:

B) No

Step-by-step explanation:

They are not similar because if you add all three angles, they add up to 179. Every triangle is supposed to have 180°.

Brock exercises every day. The function E = 15m + 5 represents the number of sit-ups he can do in m minutes. After drinking a ne

adoni [48]

Answer:

$S=45m+15$

Step-by-step explanation:

we have

E------>the number of sit-ups

m----> the time in minutes

S----> the number of sit-ups after drinking the sports drink

$E=15m+5$ ----> equation A

$S=3E$ ----> equation B

substitute the equation A in the equation B

$S=3(15m+5)$

$S=45m+15$

Solve the following equation for x: 6x-16=14

Ivenika [448]

To solve the equation for x, first, we add 16 from both sides of the equation:

$\begin{gathered} 6x-16+16=14+16, \\ 6x=30. \end{gathered}$

Now, we divide by 6:

$\frac{6x}{6}=\frac{30}{6}.$

Finally, we get that:

$x=5.$

Answer:

$x=5.$

What is the slope of line a? <br><br>

emmainna [20.7K]

<h3>Answer: -1/4 (choice C)</h3>

========================================================

Explanation:

Start at the point (0,1). This is the y intercept, which is where the graph crosses the y axis.

Then move down 1 and over to the right 4 spaces. We arrive at (4,0) which is the x intercept.

The process of "down 1, over to the right 4" can be thought of like this

rise/run = -1/4

rise = -1

run = 4

A rise of -1 indicates we go down 1 unit

The run of 4 means we move to the right 4 units

So that's why slope = rise/run = -1/4

-------------------------------------------------------

Here's another approach using the slope formula:

m = (y2-y1)/(x2-x1)

m = (0-1)/(4-0)

m = -1/4

I used the two points (0,1) and (4,0) as (x1,y1) and (x2,y2) respectively. This formula basically says "subtract the y coordinates, subtract the x coordinates in the same order, then divide the differences y over x".

-------------------------------------------------------

Side note: The line moving downhill, as we read from left to right, indicates a negative slope.

For a project, Gabrielle made a model of an Egyptian pyramid. The square base has a side length measuring 10 inches. The pyramid

Varvara68 [4.7K]

The pyramid is shown in the diagram below.
The pyramid is built from four congruent triangles and one square as the base

We have the side of the square, so the area is = 10×10 = 100

We need the height of the triangle to work out its area. We can find out by using the height of the pyramid and half of the length of the side of the square.

Using the Pythagoras rule
Height of triangle = $\sqrt{12^{2}+ 5^{2} } =13$

Area of one triangle = 1/2×10×12=60
Surface area of the pyramid = 100 + (4×60) = 340 square inches
