1. A classroom has a perimeter of 110 feet. The width is 30 feet. What is the length?

2.When you make a retail purchase in Arlington, Virginia, you pay sales tax. The formula for determining your total cost is given by:

`T=p+0.06p` where `T` is the total and `p` is the price of each item you are purchasing.



Find the total when you purchase the new iPad for $499.



(Type your answer as a number up to 2 decimal places.)
plz help me thanks

you will have 8 hours in each part.

24/3 = 8

0am to 8 am

8am to 4pm

4pm to 0am

Answer:

If we'll divide 3 to get equally in to a day.

We'll get 8hr. in each time

[tex] \frac{24 \: hr}{3} = 8 \: h[/tex]

We can imagine this as

1am - 9am

9am - 5pm

5pm - 1am

Or as u want !!

Answer:

15-ounce package is the best buy.

Step-by-step explanation:

In order to find the best-buy we have to calculate the price per ounce.

So,

For 7-ounce package:

Price =2.45$

Unit price for 7-ounce:

[tex]\frac{2.45}{7} = 0.35\$[/tex]

For 15-ounce Package:

Price: $4.95

Unit price for 15-ounce:

[tex]\frac{4.95}{15} = 0.33\$[/tex]

For 26-ounce Package:

Price: $8.84

Unit price for 26-ounce:

[tex]\frac{8.84}{26} = 0.34\$[/tex]

As we can see that the least unit price is for 15 ounce pack i.e. 0.33 per ounce so,

15-ounce package is the best buy.

Answer: 6 years

Step-by-step explanation:

Let Maria's age be x

Jonathan is four times Maria's age. This means that Jonathan age = 4x

In 3 years, he will be three times as old as Maria is then. This can be written as:

4x + 3 = 3(x + 3)

4x + 3 = 3x + 9

4x - 3x = 9 - 3

x = 6

Maria is 6 years

Answer:

5/14

Step-by-step explanation:

To work this out, we simply need to divide 1 3/4 miles by 4 9/10 miles.

1 3/4 ÷ 4 9/10

Start by converting both terms to improper fractions:

(4/4 + 3/4) ÷ (40/10 + 9/10)

= 7/4 ÷ 49/10

To divide, we simply multiply by the reciprocal of the second fraction:

7/4 * 10/49

= 70 / 196

Now we can take out common factors of the 70 / 196

70 / 196

= (5 * 2 * 7) / (14 * 2 * 7)

= 5 / 14

So the straight section of the track is five fourteenths of the entire length.

Answer:

b ≈ 4.2

Step-by-step explanation:

Using the tangent ratio in the right triangle, that is

tan50° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{5}{b}[/tex] ( multiply both sides by b )

b × tan50° = 5 ( divide both sides by tan50° )

b = [tex]\frac{5}{tan50}[/tex] ≈ 4.2 ( to the nearest tenth )

Answer:

11

Step-by-step explanation:

Since ΔNOP is a traingle, all the angles added up together equal 180 degrees.

(5x-8) + (x-5) + (6x+1) = 180

Now simplify by adding like terms

12x-12 = 180

Solve for x by adding 12 to both sides and then dividing both sides by 12

12x=192

x=16

Once you solved for x, plug it into the angle you need to find.

m∠O=(x-5)

=(16-5)

=11

Answer:

the answer is 5 5/8

Step-by-step explanation:

if you make 11 1/4 into an improper fraction, you get 45/4 (this fraction simplified would give you your original mixed number). Using the keep, change, flip rule, you would multiply 45/4 by 1/2, giving you 45/8. This fraction simplified is your answer, 5 5/8.

All you do is 2975 divided by2=1487.50

Answer:

a) 614.8km

b) $185.25

Step-by-step explanation:

25L = 265km

58L = [tex]\frac{58}{25}[/tex] × 265km

       = 614.8km

To find the cost of the petrol used, we need to find the amount of petrol used for 1007km first. You already know 265km requires 25L of petrol based on the question.

265km = 25L

1007km = [tex]\frac{1007}{265}[/tex] × 25L

             = 95L

You also know for 1L, the cost is $1.95. Thus, you can find the cost for 95L.

1L = $1.95

95L = 95 × $1.95

      = $185.25

Answer:

45 cups

Step-by-step explanation:

15x3 because there are 3 cups and 15 is one of the cups so 15x3=45

Answer:

45 Cups

Step-by-step explanation:

Use a proportion with cups in the numerator and pail in the denominator .

15/(1/3) = X/ 1

15 ÷1\3 = 15 x 3 =45 cups

Answer:

Geometric sequence

.Step-by-step explanation:

Geometric sequences are defined by an initial value and a common ratio . If a sequence does not have a common ratio or a common difference, it is neither an arithmetic nor a geometric sequence. You should still try to figure out the pattern and come up with a formula that describes it.

Answer:

[tex]Perimeter = 12 + 6y[/tex]

Step-by-step explanation:

Represent the length with x and width with y

By analysis, we have:

Length = 6 + 2 times the width.

Mathematically, the expression is:

[tex]x = 6 + 2 * y[/tex]

[tex]x = 6 + 2 y[/tex]

Required: Determine the perimeter

Perimeter of a rectangle is calculated as:

[tex]Perimeter = 2 * (Length + Width)[/tex]

Substitute x for length and y for width

[tex]Perimeter = 2 * (x + y)[/tex]

Substitute 6 + 2y for x

[tex]Perimeter = 2 * (6 + 2y + y)[/tex]

[tex]Perimeter = 2 * (6 + 3y)[/tex]

Open bracket

[tex]Perimeter = 2 * 6 + 2 * 3y[/tex]

[tex]Perimeter = 12 + 6y[/tex]

Answer:

8 miles an hour

Step-by-step explanation:

Btw that is one slow car.

Please mark brainliest.

Answer:

8 m/h

Step-by-step explanation:

In order to solve this, first understand that miles per hour is represented as [tex]\frac{miles}{hour}[/tex] So if there are 32 miles in 4 hours, then [tex]\frac{32m}{4h}[/tex] is your answer. Now 32/4 can be be simplified. The simplified version is 8 m/h.

Answer:

Yes

Step-by-step explanation:

These are congruent because according to the angle sum theorem if at least two of the angles are the same then they would be considered congruent.

Answer:

The triangles are congruent by SSS.

Step-by-step explanation:

It is marked in the diagram that sides AD and BC have equal length, and sides AB and CD have equal length. Side AC is common to both the triangles. Since  [tex]\overline{AB} \cong \overline{CD}[/tex], [tex]\overline{BC} \cong \overline{AD}[/tex], and [tex]\overline{AC} \cong \overline{AC}[/tex], it follows from SSS (side-side-side) congruence that [tex]\triangle ABC \cong \triangle CDA[/tex].

Since D=8, you input it in

5(8)-25/5=

5(8)=40

40-25= 15

15 divided by 5 is 3

Answer:

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex ad a is a multiplier

Here (h, k ) = (8, - 1 ) , then

y = a(x - 8)² - 1

To find a substitute (0, - 17 ) into the equation

- 17 = a(0 - 8)² - 1 ( add 1 to both sides )

- 16 = 64a ( divide both sides by 64 )

[tex]\frac{-16}{64}[/tex] = a , that is

a = - [tex]\frac{1}{4}[/tex]

y = - [tex]\frac{1}{4}[/tex](x - 8)² - 1 ← equation of parabola
