Answer:

angle 2=120°

angle 1=60

Step-by-step explanation:

70+50=120

or

180-(70+50)=60

angles on a straight line add up to 180°

180-60=120

Answer:

12.56 in²

Step-by-step explanation:

Area = πr²

Substitute for pi.

A = 3.14 × r²

The diameter is 4. We divide the diameter by 2 to get the radius.

4 ÷ 2 = 2

Substitute for the radius.

A = 3.14 × 2²

Solve

A = 3.14 × 4 = 12.56 in²

Answer:

No

Because you need to half the diameter to fit it into the formula. So you would do 7 divided by 2 to get the radius which is 3.5. Then you do 3.5 x pi

Answer:

228.75 inches cubed

Step-by-step explanation:

This is because the formula to find the volume of a rectangular prism is base x height x width. so if you plug in the numbers, 7 5/8 x 12 x 2 1/2, and we get our answer of 228.75 inches cubed or 228.75 in.^3

Answer:

Im guessing 252 is the answer, 42 mold spores were found 14 weeks ago and each 7 weeks it trples right? so two 7 weeks fit in 14 weeks so we would multiply 42 x 2 and which gives us 84 multiply that by 3 since it triples every 7 weeks.

School bag _ y

book _ x

system:

y+3x=180

y+5x=270

y=180-3x (and we put that instead of 'y' in the second equation)

(180-3x)+5x=270

180+2x=270

2x=90

x=45

so one book costs $45

and school bag:

y+3×45=180

y+135=180

y=180-135

y=45

Answer:

Each book costed 45$.

Step-by-step explanation:

Let x represent the price of a school bag and y represent the price of a book.

we get the following system of equations:

x+3y=180  (equation 1)

x+5y=270 (equation 2)

using equation 1: x=180-3y

then we substitute x in equation 2 in order to find y:

180-3y+5y=270

180+2y=270

2y=270-180=90

y=90/2=45

and we know that y represents the price of a book, so each book costs 45$.

Answer:

69ft² (69 square feet)

Step-by-step explanation:

8x7=56ft

6x2=12ft

2x1÷2=1ft

56+12+1=69ft²

Answer:

Option A, 69 square feet

Step-by-step explanation:

Step 1:  Determine the area of the rectangle

[tex]A = l * w[/tex]

[tex]A = 7\ ft * 8\ ft[/tex]

[tex]A = 56\ ft^2[/tex]

Step 2:  Determine the area of the second rectangle

[tex]A = l * w[/tex]

[tex]A = 6\ ft * 2\ ft[/tex]

[tex]A = 12\ ft^2[/tex]

Step 3:  Determine the area of the triangle

[tex]A = \frac{h * b}{2}[/tex]

[tex]A = \frac{(7\ ft - 6\ ft)*2\ ft}{2}[/tex]

[tex]A = \frac{1\ ft * 2\ ft}{2}[/tex]

[tex]A = \frac{2\ ft^2}{2}[/tex]

[tex]A = 1\ ft^2[/tex]

Step 4:  Determine the total area

[tex]A_{total} = 56\ ft^2 + 12\ ft^2 + 1\ ft^2[/tex]

[tex]A_{total}=69\ ft^2[/tex]

Answer:  Option A, 69 square feet

Answer:

x = 30'

2x = 60'

3x = 90'

Step-by-step explanation:

2x + 3x + x = 180

6x = 180

6x ÷6 = 180 ÷ 6

x = 30'

therefore

2x = 60"

3x = 90'

To solve this problem, we will need to use the unitary method.

Determining the equation:

⇒ 55 deliveries in 11 hours

⇒ 55 deliveries = 11 hours

Finding how much hours in 5 deliveries:

Divide both sides by x:

⇒ 55 deliveries = 11 hours

⇒ 55/x deliveries = 11/x hours

Simplify the numerators:

⇒ 55/x deliveries = 11/x hours

⇒ 5/x deliveries = 1/x hours

Use cross multiplication:

⇒ 5x deliveries = x hours

Divide both sides by x:

⇒ 5x/x deliveries = x/x hours

⇒ 5 deliveries = 1 hour

Answer:

1 hour

Step-by-step explanation:

let x = unknown number of hours

Set up ratios of deliveries to hours

[tex]\sf \implies 55 : 11 = 5 : x[/tex]

[tex]\sf \implies \dfrac{55}{11}=\dfrac{5}{x}[/tex]

Cross multiply:

[tex]\sf \implies 55x=5 \cdot 11[/tex]

[tex]\sf \implies 55x=55[/tex]

Divide both sides by 55:

[tex]\sf \implies x=1[/tex]

Therefore, 55 deliveries in 11 hours = 5 deliveries in 1 hour

Hope this helps!!

**Brainliest would be appreciated**

Answer:

Initially, as x increases, y is constant.

Afterward, the slope of the graph of the function equals 2 for all x between x = 3 and x = 5.

The slope of the graph equals -1 for x between x = 5 and x = 9.

The greatest value of y is y = 4, and it occurs when x = 5.

Step-by-step explanation:

Initially, the graph of the function is flat. The quantity y remains constant as x increases from x = 0 to x = 3. The linear equation that corresponds to the function in that region is y = 0. The slope is m = 0 because the graph is a horizontal line. The graph of the function starts to increase starting at x = 3. The slope, rise/run, once we solve it, is equal to 2 for when x is between 3 and 5. After x = 5, y starts to decrease as x increases. The slope of the graph between x = 5 and x = 9 is -1. The maximum value of y occurs at the top of the bump in the graph. The coordinates of the top of the bump are (5,4). Therefore, the maximum value is y = 4, and it occurs when x = 5.

Answer:

B.10

Step-by-step explanation:

42÷7=1. 1 child for every 6 customer. 60÷6= 10

Answer:

B

Step-by-step explanation:

If the first restaurant had 7 children within 42 customers, then we can divide 42 by 7 to get 6, which means 1 in 6 customers are children. If we apply this to the next restaurant, we will divide 60 by 6 to get 10.

This means there are 10 children in the second restaurant, so the answer is B.

Answer:

31.5p+955.5=1428

p=15

Step-by-step explanation:

31.5p+955.5=1428

−955.5 = −955.5

Subtract 955.5 from both sides

31.5p=

\,\,472.5

472.5

31.5

31.5p

​ =

31.5

472.5

​Divide both sides by 31.5

p=15

​

The number of equation players the team can bring 15 players to the tournament.

Let's break down the information given in the problem:

Total amount raised: $1428

Cost of renting a bus: $955.50

Budgeted amount per player for meals: $31.50

To determine the number of players the team can bring to the tournament (represented by "p").

The total cost for the bus and meals calculated as follows:

Total Cost = Cost of Bus + (Cost per Player × Number of Players)

Using the given values, we can write this as an equation:

Total Cost = $955.50 + ($31.50 × p)

Now we can set up the equation using the total amount raised:

Total Amount Raised = Total Cost

Substitute the values:

$1428 = $955.50 + ($31.50 × p)

Now, let's solve for "p":

$1428 - $955.50 = $31.50× p

$472.50 = $31.50 × p

To isolate "p," divide both sides by $31.50:

p = $472.50 / $31.50

p = 15
