Jose has $55 dollars and Sarah has $35. If you add both of them together you will get $90.

Let S= the amount of money Sarah has.

Let J= the amount of money Jose has

J= S+20

J+S=90

But we also know that J can equal S+20

So,

S+20+S=90

2S+20=90

2S=70

S=35

So Sarah has $35, and Jose has $35+$20, so he has 55$

Suppose an isosceles triangle ABC has A = 45° and b = c = 4. What is the length of a^2?
Mila [183]
Since b = c, the angles B and C are congruent.
180 - 45 = 135
135/2 = =67.5

A = 45
B = 67.5
C = 67.5
a = ?
b = 4
c = 4

Since we know two sides and all three angles, we can use the law of sines to find a.

b/sin B = a/sin A

4/(sin 67.5) = a/(sin 45)

a = 4(sin 45)/(sin 67.5)

a^2 = (4(sin 45)/(sin 67.5))^2

a^2 = 9.37

The large rectangle below represents one whole. What percent is represented by the shaded area? (URGENT)
nikitadnepr [17]

Answer:

40%

Step-by-step explanation:

The whole rectangle is split into 5 parts. Two out of 5 parts are shaded.

Set up a fraction:

\frac{\text{Shaded}}{\text{Whole}}=\frac{2}{5}

Convert into a decimal:

\frac{2}{5}= 0.4

Multiply the decimal by 100 to get the percent:

0.4*100=40

So, forty percent of the rectangle is shaded.

Hope this helps.
