exis [7]

Answer: 7 5/12 + 8 1/24

Step-by-step explanation:

Hi, to answer this question we simply have to add both distances driven by Jayla:

Distance driven to the post office = 7 5/12 kilometers

Distance driven to the restaurant= 8 1/24 kilometers

Mathematically speaking:

7 5/12 km + 8 1/24 km

Feel free to ask for more if needed or if you did not understand something.

Solve for x please help !!!!!!!

exis [7]

Answer:

x ≈ 20.31

Step-by-step explanation:

By applying tangent rule in the given right triangle,

tan(55°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

Measure of the opposite side = 29 units

Measure of the adjacent side = x

Substitute these values in the expression,

tan(55) = $\frac{29}{x}$

x = $\frac{29}{tan(55)}$

x = 20.306

x ≈ 20.31

Juan decided to start saving for college. He deposited $500 into an account which earns 4% simple annual interest. At the end of

Norma-Jean [14]

Answer:

$5504

Step-by-step explanation:

Given that :

Principal amount = $500

Interest = 4% simple interest annually

Amount added at the end of each year :

First year:

Principal + (Principal * rate * time)

500 + (500 * 0.04) = 520

$520 + $250 = $770

2nd year:

770 + (770 * 0.04) = $800.80

$800.80 + $250 = 1050.80

3rd year:

1050.8 + (1050.8 * 4) = 5254

$5254 + 250 = $5504

A builder needs to cover 10 square yards of floor with tile. red tile costs $60 per square yard, and white tole costs $40 per sq

dsp73

Answer:40 square yards

Step-by-step explanation:

Given

Floor area A=10 square yards

Red tile costs $\$ 60$ per square yards

White tile costs $\$40$ per square yards

Total money spent= $\$480$ on tiles

Suppose red tiles cover an area of $x$ square yards

So, we can write

$60\times x+40\times (10-x)=480\\60x+400-40x=480\\20x=80\\x=40\ \text{square yards}$

Red tiles cover an area of 40 square yards

What is the slope of the line represented by the equation y = –x + ? – –

Svetlanka [38]

For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

$y = mx + b$

Where:

m: It is the slope of the line

b: It is the cut point with the "y" axis

We have, according to the data provided, that the line is of the form:

$y = -x + b$

That means that the slope is -1.

ANswer:

$m = -1$
