Answer:

18 quarters

Step-by-step explanation:

Answer:

18 quarters 12 dimes

18 x 25 = 450

12 x 10 = 120

18 + 12 = 30

450 + 120 = 570

Therefore, there are 18 quarters.

Step-by-step explanation:

So first you multiply 6 by 55. That equals 330. Then, you divide that by 44. That equals 7.5. Therefore, Pablo runs 7.5 miles in 44 minutes.

Answer:

The answer is $12.78

Step-by-step explanation:

Answer:

So if you want to find 6% sales tax for an item costing $12, simply move the decimal point to the left two places and multiply. You will write 6% as . o6. Now multiply that by 12 to find the sales tax.

Step-by-step explanation:

Calculating Total Cost. Multiply the cost of an item or service by the sales tax in order to find out the total cost. The equation looks like this: Item or service cost x sales tax (in decimal form) = total sales tax. Add the total sales tax to the Item or service cost to get your total cost.

Calculating sales tax on a product or service is straightforward: Simply multiply the cost of the product or service by the tax rate. For example, if you operate your business in a state with a 6% sales tax and you sell chairs for $100 each, you would multiply $100 by 6%, which equals $6, the total amount of sales tax.

Answer:

The volume of the concrete needed to make the block is 5054 ft³

Step-by-step explanation:

The question relate to the calculation of the volume of a shape

The dimensions of the block are;

The depth of the block, d = 19 ft.

The width of the block, w = 19 ft.

The length of the block, l = 14 ft.

The volume of a cube, V = Length, l × Width, w × Depth, d

Therefore, the volume, 'V' of a cubic block is given as follows;

V = l × w × d = 14 ft. × 19 ft. × 19 ft. = 5054 ft.³

The volume of the concrete needed to make the block = The volume of the block, V = 5054 ft³.

Answer:

-9,4.5,90

Step-by-step explanation:

9) [tex]\frac{12xy}{x-y}[/tex]

So you basically substitute the values in for x and y which give you

[tex]\frac{12(3)(-1)}{3-(-1)}[/tex]

[tex]\frac{12(-3)}{3+1}[/tex]

[tex]\frac{-36}{4} \\-9[/tex]

10)    Same thing:

[tex]\frac{4xy}{2x} \\\\\frac{4(3)(9)}{2(3)} \\\\\frac{4(27)}{6} \\\\4.5[/tex]

11)  Same for this:

[tex]\frac{2}{3}(9x+xy)\\\\ \frac{2}{3}(9(5)(3)\\\\\frac{2}{3}( 135)\\[/tex]

3*45=135

[tex]2(45)\\90[/tex]

Based on this information, I want you to figure out the last one. If you need help reply to this answer and I will respond.

Answer:

Step-by-step explanation:

The end behavior of a function describes the behavior of the graph of the function at the "ends" of the x-axis.

The given function is ⇒⇒⇒ f(x) = 2x³ – 26x – 24

the given equation has an odd degree = 3,

and a positive leading coefficient = +2

So, the end behavior of the given function

f(x) → +∞  as  x→+∞

f(x) → -∞  as  x→-∞

Answer: 720

Step-by-step explanation:

5%=36

1%=36/5

1%=7.2

100%=7.2*100

100%=720 students

There is a total of 720 students are in Ridgewood Junior High School.

Given,
All students in Ridgewood Junior High School either get their lunch in the school cafeteria or brought it from home on Tuesday.
5% of students brought their lunch.
36 students brought their lunch.
To determine how many students in total are in Ridgewood Junior High School.

the percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Let there be x students in the Ridgewood Junior High School.
5% of students brought their lunch and equal to 36
so 5% of x = 36
5/100 * x = 36
x = 36*100/5
x = 36*20
x = 720

Thus, there is a total of 720 students are in Ridgewood Junior High School.

#SPJ2

Answer:

AB = 8

AD = 10

<A = 118

<D = 62

Step-by-step explanation:

1. AB

Because opposite sides in a parallelogram are equal, DC = AB = 8.

2. AD

Because opposite sides in a parallelogram are equal, BC = AD = 10.

3. <A

Adjacent angles are supplementary in a parallelogram, so A = 180 - 62 = 118

4. <D

Opposite angles are equal in a parallelogram, so B = D = 62

Answer:

AB = 8

AD = 10

m∠A = 28°

m∠D = 62°

Step-by-step explanation:

A few facts to remember about a parallelogram.

1.  Opposites sides are congruent

2.  Opposites angles are congruent

3.  Consecutive angles are complementary

So, AB = 8,  AD = 10,  m∠A = 90 - 62 = 28°, m∠D = 62°

Answer:

30

Step-by-step explanation:

1/2 x (a+b) x h = area

1/2 x ( 40 + x ) x 50 =  1750

1/2 (40 + x )= 1750/50

20 + 1/2x = 35

1/2 x = 35 - 20

x = 15 x 2

= 30

I hope this is right :)
