Find the area of the rhombus. A= square units

Mathematics
1 answer:
mylen [45]3 years ago
8 0

Answer: A=70 square units

Step-by-step explanation:

The area of a triangle can be found using the formula A=\frac{1}{2} bh

Let 5=h and 7=b

Plug in the values and solve

A=\frac{1}{2} (7)(5)

A=17.5

However, since four of these triangles make up this rhombus, we can multiply the area of one of these triangles by four to find the area of the whole rhombus.

A=17.5*4

A=70

Solve for the missing variable.<br> 1.)<br> 80/120 =2/x
crimeas [40]

Answer:

x = 3

Step-by-step explanation:

\frac{80}{120} = \frac{2}{x}

Simplify, divide the numerator and denominator by the same number

\frac{80}{120}\\

÷ 40

\frac{2}{3}

\frac{2}{3} = \frac{2}{x}

Cross products

2x = 2 *3\\2x = 6\\/2    /2\\\\x = 3

Agata [3.3K]

Step-by-step explanation:

We can simply by opening the brackets ,

=> y - 1 = 5( x - 2 )

=> y - 1 = 5x - 10

=> y - 5x = -9

=> 5x - y + 9 = 0

Jade got a 90% on her math quiz. She had 36 questions correct. How many questions did Jade get wrong?
Brums [2.3K]

Answer:

4 questions

Step-by-step explanation:

90% is the same as multiplying a number by 0.9. Let's say the number of questions on the quiz is x. This means the amount she got right was 0.9x. We are given this is 36, so we can set them equal and simplify:

0.9x = 36

x = 40

She must have gotten 40 - 36, or 4 questions wrong.

Answer:

A. (x-5)(x-7)

B. It means the zeroes of the graph are at (5,0) and (7,0)

Step-by-step explanation:

A

find what + what equals -12, and multiples to 35.

List all multiples of 35.

1 35

<em>5 7</em>

- 12 is negative so that means it is -5 and -7

(x-5)(x-7)

B

The factor numbers are where the zeroes on a graph are, <u>but</u> whatever is in parenthesis, the number is opposite on a graph (e.g. if it was (x-3), the zero would be (3,0)
