A cereal box says that it now contains 22% more cereal for the same price. Originally, it came with 17.4 ounces of cereal. How many ounces of cereal does the new box come with?
A) 17.4
B) 39.4
C) 21.2
D) 19.6

Answer:

y = 16.84

Step-by-step explanation:

y - 7.74 = 9.1

=> y = 9.1 + 7.74

=> y = 16.84

Answer:

25 mg. is lighter than 25 cg.

Step-by-step explanation:

Well,

The prefix "milli" means thousandth and the prefix "centi" means hundredth.  So a milligram will be one-tenth of a centigram.

10 mg. = 1 cg.

25 mg. = 2.5 cg.

2.5 cg. < 25 cg.

25 mg. is lighter than 25 cg.

Answer:

25 milligrams are lighter, because 1 milligram equivales to 1 gram multiplied by 100.

Answer:

(b) 217 cm

Step-by-step explanation:

The computation of the number of centimeters will each have is shown below:

= Length of the string ÷ number of pieces

= 10.85 meters ÷ 5

= 2.17 meters

= 217 centimeters

hence, the correct option is b.

Step-by-step explanation:

In an isosceles triangle, the angle bisector from the 3rd angle to the opposite side is a perpendicular bisector, so you split the isosceles triangle into two congruent right triangles.

This technique of 'splitting the isosceles' is used a LOT.

Answer:

x = - 6    

Step-by-step explanation:

Equation

1/3 * (-9x +12) = 22                Multiply both sides by 3

Solution

3 * 1/3(-9x + 12) = 22*3

- 9x + 12 = 66                        Subtract 12 from both sides.

-9x = 66 - 12                         Combine

-9x = 54                                Divide by -9

x = 54/-9

x = - 6

Answer:

84

Step-by-step explanation:

To complete the concrete highway with pavers 84 pavers are needed.

We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.

From the given information each Pavel has an area of 4.5 square feet.

And the area of the driveway can be obtained by multiplying the length and width of the driveway which is,

= (21×18) sq feet.

= 378 sq feet.

Therefore, The number of pavers needed is,

= (378/4.5).

= 84 pavers.

Step-by-step explanation:

Answer:

270 seconds

Step-by-step explanation:

Melissa's time = x seconds

Abby's time = (x + 30) seconds

Abby walks at a speed of 8 feet per second, and Melissa walks at a speed of 9 feet per seconds.

But, speed = [tex]\frac{distance}{time taken}[/tex]

For Abby,

8 = [tex]\frac{distance}{(x + 30)}[/tex]

distance = 8(x + 30) ................. 1

for Melissa,

9 = [tex]\frac{distance}{x}[/tex]

distance = 9x ............. 2

From equations 1 and 2, for the same distance;

8(x + 30) = 9x

8x + 240 = 9x

x = 240 seconds

Abby's time = (x + 30)

                    = (240 + 30)

                    = 270 seconds

So that Abby has been walking for 270 seconds when both students had walked exactly the same distance.

The time taken is 270 seconds.

Given that,

Based on the above information, the calculation is as follows:

8(x + 30) = 9x

8x + 240 = 9x

x = 240

So Abby time should be

= 240 +  30

= 270

Answer:

  √65 ≈ 8.06

Step-by-step explanation:

The distance formula is used for the purpose.

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((2 -(-5))² +(0 -4)²) = √(7² +(-4)²) = √(49 +16)

  d = √65 ≈ 8.0622577

The distance between C and Q is √65, about 8.06 units.

Answer:

You can figure out prime numbers by simply knowing that you can divide that number not more than one. For example, you could know that a prime number is 7 because you can only divide it once like 7 divided by 1. While for number 14, you can divide it twice which isn't a prime number because there is 14 divided by 2 and 14 divided by 1 which is more than one to divide. That's possibly an easy way to understand how to figure them out.

Answer:

A= 20 + 0.75*j

Step-by-step explanation:

Giving the following information:

You have $20 and earn $0.75 for each cup of orange juice you sell.

To calculate the total amount of dollars (A), we need to use the following formula:

A= 20 + 0.75*j

j= number of cups

For example, for 15 cups:

A= 20 + 0.75*15

A= $31.25

Answer:

9

Step-by-step explanation:

We are given that

Cost of each banana=$0.90

Cost of each orange=$0.80

Ava have total money=$15

We have to find the number of each if Ava wants to buy an equal amount of bananas and oranges at most.

Let x be the number of each.

According to question

[tex]0.9x+0.8x=15[/tex]

[tex]1.7x=15[/tex]

[tex]x=\frac{15}{1.7}[/tex]

[tex]x=8.8\approx 9[/tex]

[tex]x=9(approximately)[/tex]

Hence, number of banana bought=9

Number of oranges bought=9

Answer:

Step-by-step explanation:

If the slope is 1/5, we can interpret this as rise/run = 1/5.  We could (if we wished to do so) find the hypotenuse by using the Pythagorean Theorem:

hypo = +sqrt( 1^2 + 5^2)

In this case we dilate the triangle defined by the slope 1/5:  

2/10,        1/10/(1/2),           10/50,        etc.,       all represent right triangles whose hypotenuses lie on the same line (the line with slope 1/5).

The two right triangles are shown in the graph

The coordinates in rectangular cartesian system are of the form -

(x, y)

where -

{x} - distance along x - axis.

{y} - distance along y - axis.

Given is the slope of the line as - {m} = 1/5.

Refer to the graph attached. The line -

y = (1/5)x

is plotted. It can be seen that (0, 0) and (10, 2) lie on the line.  For two right triangles to lie on the same line, draw two perpendiculars from point (10, 2) along the {x} axis and {y} axis. Refer to the triangles shown in the graph.

Therefore, two right triangles are shown in the graph.
