Answer:

2:3

Explanation:

Pack 48                          48/2 =24

Red= 24                      24/24 : 24 / 24

Black = 24                            1:1

----------------------------------------------------------------

Pack 48                        48/2 = 24    

Red= 16                     24 / 16 : 24 / 24

Black= 24                    

16:24

4:6

Step-by-step explanation:

y=3|x|, shift right 8 units

y=3|x-8|, shift up 1 unit

y=3|x-8|+1

Answer:

Mia spent 68 dollars.

Step-by-step explanation:

The equation would be 2(13.50) + 4(10.25) = x

Solving for the first part, you get 27 for adult tickets and 41 for the children tickets. When you add the two values, you get 68.

Answer:

6280

Step-by-step explanation:

π10^2(20)

Answer:

9

Step-by-step explanation:

x^2 - 2 = 79

The first step is to get rid of the 2 on the left side. You do this by adding two on both sides. You should then get x^2 = 81.

Now, you have the just take the square root of 81, which is 9.

Answer:

25%

Step-by-step explanation:

30/40 = 0.75 = 75% paid

100-75 = 25% discount

Answer:

[tex]25\%[/tex]

Step-by-step explanation:

To find the discount of an object, one must set up the equation, the difference between the original and the paid price, over the original price, equals percent over 100. In essence;

[tex]\frac{(original-paid)}{original}=\frac{percent}{100}[/tex]

Substitute in the given values;

[tex]\frac{(40)-(30)}{40}=\frac{percnet}{100}[/tex]

Solve;

[tex]\frac{10}{40}=\frac{percent}{100}[/tex]

Simplify,

[tex]\frac{1}{4}=\frac{percent}{100}[/tex]

Cross products,

[tex]100 = 4(percent)[/tex]

Inverse operations,

[tex]100=4(percent)\\/4\\\\25 = percent[/tex]

Answer:

Step-by-step explanation:

(-2, -2)  (-1, 2)

(2 + 2)/(-1 + 2) = 4/1 = 4

y + 2 = 4(x + 2)

y + 2 = 4x + 8

y = 4x + 6

Answer:

[tex]R = 17.5[/tex]

Step-by-step explanation:

Given

P and R are complementary

[tex]Cos\ P =0.3[/tex]

Required

Find the measure of R

[tex]Cos\ P =0.3[/tex]

Take arccos of both sides

[tex]P = cos^{-1}(0.3)[/tex]

[tex]P = 72.5[/tex]

Since P and R are complementary, then:

[tex]P + R = 90[/tex]

Make R the subject

[tex]R = 90 - P[/tex]

Substitute values for P

[tex]R = 90 - 72.5[/tex]

[tex]R = 17.5[/tex]

Answer:

C. 15

Step-by-step explanation:

Absolute value is just how far away the number is on the number line and is always positive.

Answer:

4 hours

Step-by-step explanation:

It is 4 hours because you do 36 divide by 12 which is 4, Then you do 4x1= 4

Answer:

Option D) The opposite of 3 is -3. The absolute value of 3 is -3.

Step-by-step explanation:

On a number line, if you go three to the right from 0, you get 3. But if you go the same amount to the left of 0, you would get -3. I can't think of any other way to explain the opposite. The absolute value is usually the same number but the absolute value is usually the same number, but it's opposite.

I hope i explained that well and that you do well on your test!

Answer:

Range = {3, -1, 15}

Step-by-step explanation:

Domain = {0,2,-6}

function : y= -2x + 3

We replace the value of x with domain,

when x = 0

y = -2 × 0 + 3

y = 3

When x = 2

y = -2 × 2 + 3

y = -1

When x = -6

y = -2 × -6 + 3

y= 12 + 3

y = 15

Answer:

c

Step-by-step explanation:

because all the three laws are applicable for polygons

Answer:

(2x + 7) feet

Step-by-step explanation:

I'm guessing the expression there is

4x² + 28x + 49

4x² +14x +14x +49

Factorize

2x ( 2x + 7) +7( 2x + 7)

(2x + 7)²

Area = (side)1

One side is (2x +7)

Answer:

28.5

Step-by-step explanation:

28.5 delta said it was correct

Answer:

Should be A

Step-by-step explanation:

You going back 3 spaces but than having that three be divided by a positive so it's going to keep going because a negative will make a negative so that positive will be turned into a negative. -3 - 1.5 = -4.5

Answer:

y = 0.02

Step-by-step explanation:

You can see in the table that there is only one value which represents only y, (0, 0.02) since x is 0.

Hope this helps and stay safe, happy, and healthy, thank you :) !!

Answer:

(0.46, 0.52)

Step-by-step explanation:

The formula for Confidence Interval with Proportion

CI = p ± z × √p(1 - p)/n

Where

p = Proportion = x/n

x = 346

n = 706

p = 346/706

p = 0.49

z = z score of Confidence Interval 90% = 1.645

Therefore:

CI = 0.49 ± 1.645 × √0.49(1 - 0.49)/706

CI = 0.49 ± 1.645 × √0.49 × 0.51/706

CI = 0.49 ± 1.645 × 0.0188139843

CI = 0.49 ± 0.0309490042

Hence:

Confidence Interval is

0.49 - 0.0309490042

= 0.4590509958

≈ 0.46

0.49 + 0.0309490042

= 0.5209490042

≈ 0.52

Therefore , the confidence interval of the population proportion is

(0.46, 0.52)

Answer:

D

Step-by-step explanation:

This equation is in factored form. Meaning you can find the x intercepts of the graph from it. All you need to do is find reverse the numbers inside the parentese. So if its negative, make it positive, if its positive, make it negative. By doing this, you should find that the x-intercepts of this graph are 2 and 3 and the donly graph with x-intercepts at these places is graph d.

Answer:

y = 8

x = 4

Step-by-step explanation:

This is a special right triangle with angle measures of 90 60 30 and the side lengths are represented by a - a√3 - 2a

The side length that sees angle measure 30 is a

The side length that sees angle measure 60 is a√3

The side length that sees angle measure 90 is 2a

if the side length that sees angle measure 60 is given as 4√3 then that means a = 4

so x = 4 and 2x = 8

Answer:

60

Step-by-step explanation:

Im too lazy

180-117=63

3y+12+63+4y=180

7y+75=180

7y=105

y=15

4(15)=60

Can i get brainliest?

Answer:

<A=60

Step-by-step explanation:

3y+12+4y=117

solve for y (y=15),

then fill in 4(15)
