There are 30 students in Mrs.

Woodward’s class and 15 of the class has their own cell phone. Of this group of students, 12 of them

are allowed to use social media. How many of the students have a cell phone and can use social media?

There are two up there

Answer:

1. $56,000

2. $3,695

3. $1,644.48

Step-by-step explanation:

1. Equity = valuation - mortgage

              = $250,000 - $180,000

              = $70,000

80% = 80/100 = 0.8

Therefore, 80% of the equity = 0.8 × $70,000

                                                = $56,000

2. Total charges = jewelry charge + electronics charge

                            = $2,450 + $1,245

                            = $3,695

3.

First credit card:

Total payment = two years × monthly payments

                        = 2 × 12 × $252.04

                        = $6,048.96

Interest = total payment - balance

             = $6,048.96 - $5,000

            = $1,048.96

Second credit card:

Total payment = two years × monthly payments

                        = 2 × 12 × $381.72

                        = $9,161.28

Interest = total payment - balance

             = $9,161.28 - $7,500

             = $1,661.28

Home equity loan:

Total payment = two years × monthly payments

                        = 2 × 12 × $565.24

                        = $13,565.76

Interest = total payment - balance

             = $13,565.76 - $12,500

             = $1,065.76

Money saved = (total of interest from credit cards) - home equity loan interest

                      = ($1,048.96 + $1,661.28) - $1,065.76

                      = $1,644.48

Answer:

1) B. Combine-like terms

2) A. Subtraction Property of Equality

3)D. Division Property of Equality

Step-by-step explanation:

Answer:

We can assume angles 102° and angles 0 and 42° are alternate interior angles.

So, to solve for 0, we must add this unknown angle to 42° and make it equal to 102°;

Let's make '0', x(our variable we solve for)

x + 42 = 102

-42         -42

x = 60

Answer:

a

Step-by-step explanation:

the nth term of an arithmetic sequence is

[tex]u_{n}[/tex] = u₁ + (n - 1)d

given u₂₀ = 100 and u₂₅ = 115 , then

u₁ + 19d = 100 → (1)

u₁ + 24d = 115 → (2)

subtract (1) from (2) term by term to eliminate u₁

0 + 5d = 15

5d = 15 ( divide both sides by 5 )

d = 3

substitute d = 3 into (1) and solve for u₁

u₁ + 19(3) = 100

u₁ + 57 = 100 ( subtract 57 from both sides )

u₁ = 43

Answer:

a) u₁ = 43, d = 3

Step-by-step explanation:

Given :-

u₂₀ = 100

u₂₅ = 115

To Find :-

u₁ and d

Solving :-

u₂₀ = u₁ + 19d = 100 -(1)

u₂₅ = u₁ + 24d = 115 -(2)

(2) - (1)

5d = 15

d = 3

u₁ + 19(3) = 100

u₁ + 57 = 100

u₁ = 43

Solution :-

a) u₁ = 43, d = 3

Answer:

[tex]\huge\boxed{\text{(A)}\ 96 \textdegree}[/tex]

Step-by-step explanation:

A parallelogram has two pairs of identical angles.

The identical angles will be directly opposite from each other.

This means that:

Therefore, we can say that Angle A is 3x degrees and Angle B is x+52 degrees.

It's also important to note that all angles in a quadrilateral add up to 360°.

Since we know the measure of each angle, we can add up the expressions for each and find x.

[tex]3x + 3x + (x+52) + (x+52) = 360[/tex]

Let's simplify this equation.

Now that we know the value of x, let's use it to find the measure of Angle A.

We already proved earlier that Angle C is equivalent to Angle A. Since we know the expression for Angle C (3x) it'll be the same for angle A.

[tex]3(32)=96[/tex]

So A is 96°

Answer:

There are 68 students in the class after these changes.

Step-by-step explanation:

g = number of girls

b = number of boys

Because the ratio of girls to boys is 3:1, initally the equation was  

g = 3b                

Finally, we have

g-1 girls because one girl dropped the class

b+3 boys because three more boys signed up

Because the new ratio of girls to boys is 5:2, the new equation is  

(g - 1)/(b + 3) = 5/2

Cross multiply.

2(g - 1) = 5(b + 3)

2g - 2 = 5b + 15

2g - 5b = 17          

Then, substitute g (which is 3b because the first equation was g = 3b)

2(3b) - 5b = 17

b = 17

g = 3b = 3*17 = 51

g = 51

The final number of students in the class = 17 + 51 = 68

Answer: 68

Answer:

55°, 125°

Step-by-step explanation:

angle EFG = 180°

angle EFH + angle GFH = angle EFG (Colinearity)

substitute the values,

6x - 5 + 12x + 5 = 180°

18x = 180°

(÷18)

x = 10

substitute values of x in both the requires angles,

angle EFH

= (6 × 10) -5

= 55°

angle GFH

= (12 × 10) + 5

=125°

to check,

55° + 125° = 180°

Step-by-step explanation:

Answer:

20% of 50 = 10

Step-by-step explanation:

1. Convert the problem to an equation using the percentage formula: P% * X = Y

P is 20%, X is 50, so the equation is 20% * 50 = Y

2. Convert 20% to a decimal by removing the percent sign and dividing by 100: 20/100 = 0.2

3. Substitute 0.2 for 20% in the equation: 20% * 50  = Y becomes 0.2 * 50 = Y

4. Do the math: 0.2 * 50 = 10

5. Final answer: 20% of 50 is 10

Answer:

5:4

Step-by-step explanation

If your shoes to flip-flops are 10:8 then the starting ratio will be 10:8 but 10 and 8 are both divisible to 2 so you can simplify 10:8 to 5:4

Newton's third law states that if object A exerts a force on object B, object B must respond with a force of equal size and in the opposite direction. This law reflects nature's symmetry: forces always exist in pairs, and one body cannot exert a force on another without experiencing one.

The distributive property of multiplication over addition can be used when you multiply a number by a sum. For example, suppose you want to multiply 3 by the sum of 10 + 2. 3(10 + 2) = ? According to this property, you can add the numbers and then multiply by 3.

The equation 3x - 4y = 16 is now in standard form, where A = 3, B = -4, and C = 16.

To convert the equation y = (3/4)x - 4 into standard form, we need to eliminate any fractions and rewrite it in the form Ax + By = C, where A, B, and C are integers.

The given equation is already almost in standard form, but we can proceed with the following steps:

Step 1: Multiply both sides by 4 to eliminate the fraction:

4y = 3x - 16

Step 2: Move all terms to one side of the equation to have zero on the other side:

3x - 4y = 16

The equation 3x - 4y = 16 is now in standard form, where A = 3, B = -4, and C = 16.

A recipe for 12 waffles calls for 1 1/2 cups of milk, 2 1/4 cups of flour, and 1 1/3 cups of other ingredients.

Answer:

A 5 1/12 cups of ingredients

B 10 1/6 cups of ingredients

C The total amount of ingredients for 12 waffles would increase from the original recipe.

D 7.56 or 7 5/9 recipes

Step-by-step explanation:

A... What is the total number of cups of ingredients needed for 12 waffles?...

The total number of cups of ingredients needed =

1 1/2 cups of milk + 2 1/4 cups of flour + 1 1/3 cups of other ingredients

(1 + 2 + 1) + (1/2 + 1/4 +1/3)

4 + ( 6 + 3 + 4/12)

4 + (13/12)

4 + (1 1/12)

B... What is the total number of cups of ingredients needed for 36 waffles? ....

If 12 waffles requires = 5 1/12 cups of ingredients

36 waffles =

Cross Multiply

= (36 waffles × 5 1 /12)/12 waffles

= 10 1/6 cups of ingredients

C... If the milk is reduced to 1 cup and the amount of 'other ingredients' (not including the flour) is increased to 2 cups, would the total amount of ingredients for 12 waffles increase or decrease from the original recipe?

Justify your thinking...

Original recipe.

A recipe for 12 waffles calls for 1 1/2 cups of milk, 2 1/4 cups of flour, and 1 1/3 cups of other ingredients = total of 5 1/12 cups of ingredients

Current recipe

1 cup of milk + 2 1/4 cups of flour + 2 cups of other ingredients

1 + 2 + 2 + (1/4)

5 1/4 cups of ingredients

Therefore, total amount of ingredients for 12 waffles would increase from the original recipe. This is because when you subtract 5 1/12 from 5 1/4 you get a difference of 1/6 cups

5 1/4 - 5 1/12 = 1/6

D... If a baker has a 5 pound bag of flour, which is approximately 17 cups of flour, how many complete recipes for 12 waffles can the baker make?... Justify your thinking...

The original recipe has 2 1/4 cups of flour as its quantity for 12 waffles

Hence:

2 1/4 cups of flour = 12 waffles

17 cups =

17 × 12/2 1/4

= 204÷ 2 1/4

= 204 ÷ 9/4

Given

Total no. of waffles required = 12

No. of  cups of milk = [tex]1\frac{1}{2}[/tex]

No. of cups of flour  = [tex]2\frac{1}{4}[/tex]

No. of cups of other ingredients = [tex]1\frac{1}{3}[/tex]

The total number of cups of ingredients needed for 12 waffles =
