Please help heads up it’s not 480 I’ve tried that

Answer:

78 degrees

Step-by-step explanation:

Mainly because the measure of the arcs intercepted by the interior angles equals 2 times those interior angles.

so arc DC =  2 * angle DBC = 2 * 51 degrees = 102 degrees.

We also see that because BD is a diameter the angle  BCD that intercepts it is 90 degrees because   half-circle arc BD = 2 * angle BCD

180 degrees = 2 * angle BCD

also we want arc BC.

we know that the total circle is the sum of all 3 arcs.

arc BC + (half-circle) arc BD + arc DC = 360 degrees

arc BC + 180  + 102 = 360 degrees.

arc BC =  360 - 180 - 102 = 78 degrees

Answer is 6/25

because you have to add all the marbles wich will be:

four yellow marbles, six red marbles, five blue marbles, six white marbles, six white marbles

4 + 6 + 5 + 6 + 4 = 25

so there is 6 white marbles and a total of 25 marbles so it will be 6/25

Step-by-step explanation:

Answer:

The answer to this question can be defined as follows:

net paid interest = $ 655. 04

Total cost = $ 4955.04

Step-by-step explanation:

Given values:

loan amount = $ 4,300

monthly payment = $ 206.46

interest rate = 14 %

Time = 2 years

Solution:

yearly payment = one month amount × 12

1 year payment = $ 206.46 × 12

1 year payment =  $2477.52

because Time is 2 year then payment is = $2477.52 *2

2 year payment = $ 4955.04

net interest paid  = total payment - loan amount

                            = $ 4955.04 - $4300

                            = $ 655.04

total  cost = $ 4955.04

net paid interest = $ 655.04

The total cost of repayment and the interest should be $4,955.04 and $655.04.

Since

loan amount = $ 4,300

monthly payment = $ 206.46

interest rate = 14 %

Time = 2 years

Now

yearly payment = one month amount × 12

So,

= $ 206.46 × 12

=  $2477.52

Now the two year payment should be

= $2477.52 *2

= $ 4955.04

Now

net interest paid  = total payment - loan amount

= $ 4955.04 - $4300

= $ 655.04

hence, The total cost of repayment and the interest should be $4,955.04 and $655.04.

[tex]180(n - 2)[/tex]

you have to put the number of sides for n

[tex]180(n - 2) \\ 180(6 - 2) \\ 180 \times 4 \\ = 720[/tex]

720 is the sum of interior angles. so to find the value of an angle you have to divide 720 by the number of angles.

Answer: Sally has 48 in her piggy bank

Step-by-step explanation:

Hi, to answer this question, first, we have to add the coins given to Sally:

37 +21 +22 = 80

Since she lost 32 coins before putting those coins into her piggy bank, we have to subtract that number to the total number of coins collected.

80-32 = 48 coins

Sally has 48 in her piggy bank

[tex]12.5%[/tex]%

Step-by-step explanation:

[tex]\frac{25}{200}[/tex] is simplified to [tex]\frac{1}{8}[/tex], which in "perfect form," is [tex]12.5%[/tex]%

Answer:

12.5%

Step-by-step explanation:

$2 = 200c

200c ........ 100%

25c ................x%

x = 25×100/200

= 25/2

= 12.5%

Answer:

x=2

Step-by-step explanation:

We will use the secant-secant Formula:

(whole secant) x (external part) =         (whole secant) x (external part)

(1+x+4) * (x+4) = (11+x+1) * (x+1)

Combine like terms

(x+5) (x+4) = (x+12) (x+1)

FOIL

x^2 + 4x+5x + 20 = x^2 +  x+ 12x + 12

Combine like terms

x^2 + 9 x + 20 = x^2 + 13 x + 12

Bring everything to the left

x^2 + 9 x + 20- (x^2 + 13 x + 12) = x^2 + 13 x + 12-( x^2 + 13 x + 12)

x^2 + 9 x + 20- (x^2 + 13 x + 12) =0

Distribute the minus sign

x^2 + 9 x + 20- x^2 - 13 x - 12 =0

Combine like terms

-4x +8 = 0

Subtract 8 from each side

-4x+8-8=0-8

-4x=-8

Divide each side by -4

-4x/-4 = -8/-4

Answer: 942.48 [tex]Units ^{3}[/tex]

Step-by-step explanation:

First we find the area of the base (the circle) the formula for that is [tex]\pi r^{2}[/tex]

the radius is 5 because it is half the diameter.

so our base is 78.54

then we multiply that by the height

so 78.54 times 12 = 942.48

To find the wingspan of the real aeroplane, we use the scale of 5 cm to 13 m and set up a proportion comparing the model's wingspan of 24 cm with the real wingspan, which results in a real wingspan of 62.4 m.

Sunita's scale model of an aeroplane has a wingspan of 24 cm, and the scale used is 5 cm to 13 m. To find the wingspan of the real aeroplane, we set up a proportion where 5 cm on the model represents 13 m in reality. The ratio would be:

Model scale: 5 cm

Real scale: 13 m = 1300 cm (since 1 m = 100 cm)

Now we find the corresponding real-life measurement for the 24 cm wingspan on the model:

(5 cm / 1300 cm) = (24 cm / Wingspan in cm)

To solve for the real wingspan, we cross-multiply and divide:

5 cm * Wingspan in cm = 1300 cm * 24 cm

Wingspan in cm = (1300 cm * 24 cm) / 5 cm

Wingspan in cm = 31,200 cm / 5 cm

Wingspan in cm = 6,240 cm

Converting back to meters (divide by 100 since 1 m = 100 cm):

Wingspan in m = 6,240 cm / 100 = 62.4 m

37.5 or 37 1/2

Step-by-step explanation:

The formula for finding surface area in a cube is A=6a^2

substituting 2.5 instead of a will result in this equation. A=6(2.5)^2

solving algebraically will then get you to your answer of 37.5

Answer:

Step-by-step explanation:

Each cube has six faces. All faces are congruent and each of them is a square.

The fromula of an area of a square is:

[tex]A=s^2[/tex]

s - length of a side of a square

We have

[tex]s=2\dfrac{1}{2}[/tex]

Convert it to a decimal

[tex]s=2\dfrac{1}{2}=2.5[/tex]

Answer:

Inequality=0.75x∠10   Answer=13 or less

Step-by-step explanation:

Answer:

y=.75x (13 Times)

Step-by-step explanation:

y is the amount it will cost Montel to play the video game x amount of times, if Montel plays the game 2 times, 2x.75 is $1.50 so it would cost him $1.50 to play the game 2 times. However, we want to find how many times he can play with a $10 budget, so we must enter $10 as y and divide by .75 and we should get 13.33333. This means Montel will be able to play 13 times and will have 25 cents left over because 13 x .75 is $9.75

Answer:

16 men would be needed to paint the room in 2 hours

Step-by-step explanation:

We can use proportion to solve the problem given, but first we need to determine whether it is a direct or indirect proportion.

If the number of men are increase, the time taken to do the work will decrease, If the number of men are decrease, the time taken to do the work will increase. Therefore, this is an indirect proportion.

We are going to arrange the data inversely.

Let x be the number of men needed to paint the room in two hours

8 hours =  2 hours

    x        = 4 men

Cross-multiply

2×x = 8×4

2x = 32

Divide both-side of the equation by 2

2x/2 = 32/2

x = 16 men

16 men would be needed to paint the room in 2 hours

Answer:

Using a system of equations, however, allows me to use two different variables for the two different unknowns.

number of adults: a

number of children: c

With these variables, I can create equations for the totals they've given me:

total number: a + c = 2200

total income: 4a + 1.5c = 5050

Now I can solve the system for the number of adults and the number of children. I will solve the first equation for one of the variables, and then substitute the result into the other equation:

a = 2200 – c

4(2200 – c) + 1.5c = 5050

8800 – 4c + 1.5c = 5050

8800 – 2.5c = 5050

–2.5c = –3750

c = 1500

Now I can back-solve for the value of the other variable:

a = 2200 – (1500) = 700

I have values for my two variables. I can look back at my definitions for the variables to interpret these values. To answer the original question, there were:

1500 children and 700 adults.

Final answer:

A word problem involving two people and their apples, where Alice has twice as many apples as Bob. The variables are defined, the equation is written, and the solution is found.

Explanation:

Word Problem:

Alice has twice as many apples as Bob. Together, they have 15 apples. Define the variable 'x' as the number of apples Bob has.

Equation:

Alice's apples: 2x

Bob's apples: x

2x + x = 15

Solution:

Combining like terms: 3x = 15

Dividing both sides by 3: x = 5

Sentence Explanation:

We defined the variable 'x' as the number of apples Bob has. Since Alice has twice as many apples, we expressed her number of apples as 2x. The total number of apples they have together is 15, so we created an equation by summing up both Alice's and Bob's apples. By solving for 'x', we found that Bob has 5 apples.

Answer:

There were 20 questions on the quiz

Step-by-step explanation:

In this question, we are concerned with knowing the number of questions on a quiz, given that Deana had a certain percentage after scoring an amount of marks.

We proceed as follows;

Let the number of questions on the quiz be X.

Now, she got 85% by making 3 incorrect choices. This means the percentage of questions she got incorrectly would be 100-85 = 15%

what we are saying is that it is just 15% of her questions that were wrong.

This mathematically;

15% of x = 3

15/100 * x = 3

15x = 3 * 100

15x = 300

x = 300/15

x = 20
