HELP THIS IS FOR MY FINAL GRADE

Damm [24]

Answer:

Ida makes $ 6960 in 5 weeks.

Step-by-step explanation:

Let the profit of the first week is p.

p = $ 600

Total profits of the five weeks

= p + (p + 0.15p) + (p + p +0.15 p) + (p + p + p + 0.15 p) + (p + p + p + p + 0.15 p)

= 11 p + 0.6 p

= 11 x 600 + 0.6 x 600

= 6600 + 360

= $ 6960

So, Ida makes $ 6960 in 5 weeks.

Find the area of a square whose diagonal length is 32 CM

BigorU [14]

Answer:

512cm^2

Step-by-step explanation:

Let's imagine cutting the square down that diagonal. Now, we have two isosceles right triangles with a hypotenuse with length 32cm. Let's take one of those triangles for now and focus on it. Let's give the one of the legs of a triangle some length x. Since both legs are the same length, by the Pythagorean theorem:

$x^2+x^2=32^2\\\\2x^2=1024\\\\x^2=512\\\\x=\sqrt{512}$

Since this leg makes up one side of the square, we can use it to calculate the area of the square, which is just the side length squared:

$A=(\sqrt{512})^2 = 512$

Valeria has been training for the Charlestown cruisers bike race. The first week she trained, she rode 5 days and took the same

ira [324]

The number of miles covered every evening obtujwd using a <em>system of equation</em> is 15 miles.

<u>Let the number of miles per evening</u> = m

Number of days = 5

Number of miles per morning = 8 miles

Total miles covered = 115 miles

<u>Using the expression below :</u>

<em>Number of days(miles per morning + miles per evening) = 115 miles </em>

5(8 + m) = 115

40 + 5m = 115

5m = 115 - 40

5m = 75

m = 75 / 5

m = 15 miles

Therefore, the Number of miles covered per evening is 15 miles.

In ΔXYZ, XY = 6.32, YZ = 5.83, and XZ = 11.05. m∠Y = º.

Dominik [7]

Answer: 130.8 degrees

Explanation:

The problem can be solved by using the cosine theorem:

$a^2 = b^2 + c^2 - 2bc cos \alpha$ (1)

where

a,b,c are the lengths of the three sides of the triangle

$\alpha$ is the angle between b and c

In this problem, we can identify a,b,c, with:

a = XZ = 11.05

b = XY = 6.32

c = YZ = 5.83

So, the angle $\alpha$ corresponds to the angle m∠Y. Re-arranging eq.(1), we find

$cos \alpha = \frac{b^2+c^2-a^2}{bc}=\frac{(6.32)^2+(5.83)^2-(11.05)^2}{2(5.83)(6.32)}=-0.654$

So, the angle is

$\alpha=cos^{-1}(-0.654)=130.8^{\circ}$
