Question 1

Find the missing side length.

5*5=25+ 7*7=49= 74 so 8.6

Question 2

What is the area of the parallelogram?

18*50=900

Question 3

What is the perimeter of the figure?

If you break the object apart. 7+7+1+1=16

5+5+3+3=16

16+16=32m

Question 4

What are the solutions to the equation?

x^2 – 22 = 14

I found that 6*6=36 – 22=14

I tried a few numbers .

Question 5

What is the area of the figure?

If you break the figure apart. 3*2=6

2*6=12

6+12=18cm

Question 6

What is the area of the trapezoid?

11+3=14*9=126*2=252

Question 7

Hint: 1 Revolution equals the Circumference!

How far does a wheel travel in 2 revolutions if it has a radius of 45 cm?

2*3.14=6.28*45=282.6*2=565.2

Question 8

The diameter of the larger circle is 11 cm. The diameter of the smaller circle is 7 cm. What is the area approximate area of the shaded region?

For the smaller one – 7/2= 3.5 *3.5*3.14=38.46

For the bigger one- 5.5*5.5*3.14=94.98

94.98-38.46=56.52

Question 9

What is the approximate area of a circular garden that has a diameter of 12 feet?

A= Pi*r2. 3.14*6^2 =113

6*6=36*3.14= 113.04

Question 10

A 17-foot pole is leaning against a wall. The bottom of the pole is 8 feet away from the bottom of the wall. Approximately how high up the wall does the top of the pole reach?

(a^2+b^2=c^2) Its 15 ft

Factor this problem ?<br> 125 +27y^3

koban [17]

Answer:

(5 + 3y)(25 - 15y + 9y²)

Step-by-step explanation:

This is a sum of cubes and factors in general as

a³ + b³ = (a + b)(a² - ab + b²), thus

125 + 27y³

= 5³ + (3y)³ with a = 5 and b = 3y

= (5 + 3y)(5² - 5(3y) + (3y)² )

= (5 + 3y)(25 - 15y + 9y²)

You have 8 times as many dimes as nickels. You have 18 dimes

fenix001 [56]

Answer:

$1.70

Step-by-step explanation:

Let the number of nickels be $x$ .

Thus, by the problem statement, the number of dimes is [/tex] 8 \cdot x = 8x. [/tex]

Therefore, there are $8x + x = 9$ coins in total. To find what $x$ is, we need to solve the equation $9x = 18.$ This can be done by dividing both sides by $9$ which gives $x=2$ . Plugging these values in tells us that there are $2$ nickels and $16$ dimes. (Test it out!) Thus, the nickels are worth $2 \cdot 5 = 10$ cents and the dimes are worth $16 \cdot 10 = 160$ cents, so in all, you have $10 + 160 = 170$ cents which is $1.70.

Hope this helps :)

Converse of the Pythagorean theorem

jonny [76]

I only know how to do # 7.

7. 4.5^2 + 6^2 = 7.5^2
20.25 + 36 = 56.25
56.25 = 56.25

yes, the card is a right triangle because A and B added together equals the same as C

Your answer must be simplified.

JulijaS [17]

Answer:

The simplified form is $x\geq -99$ .

Step-by-step explanation:

Given : Expression $\frac{x}{3}\geq -33$

To find : The simplified expression ?

Solution :

Expression $\frac{x}{3}\geq -33$

Multiply 3 both side,

$\frac{x}{3}\times 3\geq -33\times 3$

$x\geq -99$

Therefore, the simplified form is $x\geq -99$ .
