PLEASE ANSWER!!!

Answers

Answer 1

Answer:

36

Step-by-step explanation:

9 times 4 buddy

Answer 2
area of square = side length ^2
area = 81 so side length ^2 = 81
square root each side
side length = 9
perimeter of square = 4 x side length
= 4 x 9 = 36cm

Answer:

x = 36°

Step-by-step explanation:

x + 20° + 4x = 200° { exterior angle of a triangle is equal to the sum of two opposite interior angles }

5x = 200° - 20°

5x = 180°

x = 180° / 5

x = 36°

Need help on this please help

Answers

Answer:

204

Step-by-step explanation:

The area of the top triangle = 5*12/2 =                        30

The area of the bottom triangle =                                30

The hypotenuse of the top triangle is

5^2 + 12^2 = hypotenuse^2

25 + 144 = hypotenuse^2

169 = hypotenuse squared.

hypotenuse = sqrt(169)

hypotenuse = 13

Now the back face = 13 * 8 =                                       104

The area of the left side rectangular  face = 5*8 =     40

The total area = 30 + 30 + 104 + 40 =                        204

The ratio of male to female students in a junior high
school is 13:17. Find the total population of the

plsss.......answer ​

Answers

the total no of population=1650

13:17 first add the two numbers 13+17=30

then 13/30×y =715 , i make 13 at the numerator because it's males ratio

after that 30/13×13/30y =715 ×30/13

y =715×30/13

y =1650

after u find the total no it's simple to find the no of females

2. Distribute. You will end up with 0 = -3n

3. Divide both sides by -3. n = 0

Step-by-step explanation:

Answer:

n=0

Step-by-step explanation:

3(-4+4)+5n=2n

first distribute

-12+12+5n=2n

combine like terms

5n=2n

subtract 2n on both sides

3n=0

divide by 3 on both sides

n=0/3

Anna has a recipe for pumpkin bars. She uses 2 ½ cups of sugar for every 3 pans of pumpkin bars. AJ wants to follow the same recipe. He will make h pans of pumpkin bars using g cups of sugar. Which of these equations best represents the relationship between h and g?

Answers

Answer:

[tex]2.5h = 3g[/tex]

Step-by-step explanation:

Given

[tex]Sugar = 2\frac{1}{2}\ cups[/tex]

[tex]Bars = 3\ pans[/tex]

Required

Determine the equation for h pans and g cups

We have that:

[tex]Sugar = g[/tex]

[tex]Bars = h[/tex]

To do this, we make use of the following equivalent ratios.

[tex]Bars : Sugar = Bars : Sugar[/tex]

So, we have:

[tex]3 : 2\frac{1}{2} = h : g[/tex]

Express fraction as decimal

[tex]3 : 2.5 = h : g[/tex]

Express as fraction

[tex]\frac{3}{2.5} = \frac{h}{g}[/tex]

Cross multiply

[tex]2.5h = 3g[/tex]

A) 0
B) 1
C) 8
D) infinitely many​

Answers

9514 1404 393

Answer:

  D)  infinitely many

Step-by-step explanation:

There are infinitely many points on any portion of the number line. The shading on the graph indicates all numbers less than or equal to 8 are solutions. There are infinitely many such numbers.

A 2-column table with 9 rows. The first column is labeled year with entries 1970, 1975, 1980, 1985, 1990, 1995, 2000, 2005, 2010. The second column is labeled pounds of trash with entries 3.25, 3.25, 3.66, 3.83, 4.57, 4.52, 4.74, 4.69, 4.44.
The table shows the average number of pounds of trash generated per person per day in the United States from 1970 to 2010. Use the statistics calculator to calculate the mean and median. Round the answers to the nearest hundredth.

Answers

Answer:

The median of a list of numbers is the center number when you order the numbers from least to greatest.

Since there are 9 numbers; the center number is the fifth number. Four numbers below and four numbers above. Median is 4.44 and the mean or average is 4.09.

Step-by-step explanation:

List in order from least to greatest

(3.25, 3.25, 3.66, 3.83)  4.44  ( 4.52, 4.57, 4.69, 4.74) Notice 4 numbers below 4.44 are lower and 4 numbers above 4.44 are higher.  So the median number is 4.44

For the mean you add all the number and divide the sum by the number of numbers you have. We know you have 9 numbers from the first part. So, add the numbers from the list (3.25 +3.25+ 3.66 + 3.83 + 4.44 + 4.52 + 4.47 + 4.69 + 4.74)  = 36.85  Then divide by 9 = 4.09


5. Suppose you invested PHP 25,000 at a simple interest at a rate of 2.5%, how much will be your investment after
10 years? a. PHP 43,750.00
C.PHP 45,730.00
b. PHP 31,250.00
d. PHP 47,350

Answers

Answer:

b. PHP 31,250.00

Step-by-step explanation:

Simple interest = principal × rate × time

Principal = PHP 25,000

Rate = 2.5%

Time = 10 years

Simple interest = principal × rate × time

= PHP 25,000 × 2.5% × 10

= 25,000 × 0.025 × 10

= 6,250

Simple interest = PHP 6,250

Investment after 10 years = principal + simple interest

= PHP 25,000 + PHP 6,250

= PHP 31,250

Investment after 10 years = PHP 31,250

b. Does the solution of your equation solve the original problem? Explain.

Answers

Answer:

a) x = 34

b) yes, it checks out

Step-by-step explanation:

2x - 5 = 3(4 + 1/2x)

multiply both sides by 2 to eliminate fraction

2[2x - 5 = 3(4 + 1/2x)] = 4x - 10 = 24 + 3x

x - 10 = 24

x = 34

check

2(34) - 5 = 3(4 + 34/2)

68 - 5 = 3(4 + 17)

63 = 3(21)

63 = 63
