Simplify the following

5/8 × 6/7

Answers

Answer:

15/28

Step-by-step explanation:

5/8 × 6/7

multiply the numerators by numerators and denominators by denominators

5×6= 30

8×7= 56

30/56 simplified to give 15/28

Answer:

15/28

Step-by-step explanation:

5×6 = 30

8×7 = 56

so we have 30/56

which then we simplify by 2

30÷2 = 15 & 56÷2 = 28

= 15/28

Josiah kept track of how many songs of each genre were played in an hour from his MP3 player. The counts are displayed in the table below. He has a total of 1,500 songs on his player.

Josiah’s work:

StartFraction 10 over 20 EndFraction = StartFraction x over 1,500 EndFraction. StartFraction 10 times 30 over 20 times 30 EndFraction = StartFraction x over 1,500 EndFraction. 300 = x.
He should have found the average of the number of rock songs by averaging 4 and 6 to get 5.
He did not multiply the numerator and denominator by the correct number to equal 1,500.
His answer will be one-half of what he got because he did not divide 10 by 2 when setting up the proportion.
He can only solve the proportion by multiplying the numerator and denominator by a common multiple.
He should have multiplied the numerator and denominator by 75, not 30, because 20 times 75 = 1,500.

how do you find surface area with a detail explanation.
giving briniest.

Answers

Surface area is the total area on the surface of a three-dimensional shape. The main formula you can use is SA = 2lw + 2lh + 2hw. This means that you would first multiply the length by the width and multiply that product by 2, multiply the length and the height and multiply that product by 2, and lastly multiple the width and the height and multiply that product by 2. After you multiply what you need to multiply, you add all of your products together, thus resulting in the surface area of the figure.

The formula for surface area depends on the shape

PLEASE ANSWER QUICKLY

Answer:

(3,3)

Answer:

The prime factorization of 1008 is:

1008 = 2^4 × 3^2 × 7

The prime factorization of 1323 is:

1323 = 3 × 19 × 23

To reduce 1008/1323, we need to simplify the fraction by dividing the numerator and denominator by their greatest common factor (GCF). To find the GCF of 1008 and 1323, we can use their prime factorizations. The only common prime factor they share is 3, so the GCF is 3.

1008/1323 = (3 × 336)/(3 × 441) = 336/441

We can simplify this fraction further by dividing both the numerator and denominator by 7, which is the GCF of 336 and 441.

336/441 = (7 × 48)/(7 × 63) = 48/63

Finally, we can simplify this fraction by dividing both the numerator and denominator by their GCF, which is 3.

48/63 = (3 × 16)/(3 × 21) = 16/21

Therefore, 1008/1323 simplified is 16/21.

If y = 17 inches, z = 24 inches, h = 7 inches, and w = 3 inches, what is the area of the object?

Answers

The base of triangle = z
Area of triangle =0.5*base*y
0.5*24*17=84
Area of rectangle=z*w
=24*3=72
Area of the object = area of triangle+area of rectangle
=84+72=156

The main answer is 8,568 inches.

Explanation:
Area is the product of all the side multiplied. Using this knowledge, you can figure out that 7x3 is 21 multiplied by 17 is 357 then multiplied by 24 is 8,568, thus showing that the answer is 8,568 inches.

The surface of the cuboid below is 128cm squared. Find the length x.

Answers

Answer:

x = 6 cm

Step-by-step explanation:

The surface area: 128 cm^2

32 + 16x = 128

Note: The surface area of a cuboid consists of 6 faces

16x=96 -> x = 6

Answer:

Step-by-step explanation:

The total surface area = 2(lb+lh+bh)

With given information, 2(4x+4x+4*4) = 128

=> 2(8x+16) = 128

=> 16x + 32 = 128

=> 16x = 96

=> x = 6

Therefore, the length = 6

A steak costs $4 more than a hamburger, and a hamburger costs $4 more than a grilled cheese sandwich. If six grilled chees sandwiches cost 2x dollars, how much will 4 steaks and 2 hamburgers cost?

(I understood this question but I don't know why I am keep getting the wrong answer lol)

Answers

Answer:

6(x/3)+ 40= 2x+ 40.

Step-by-step explanation:

Let "C" be the cost of a grilled cheese sandwich.

"A hamburger costs 4 more than a grilled cheese sandwich" so a hamburger costs C+ 4.

"A steak costs 4 more than a hamburger" so a steak cost (C+ 4)+ 4= C+ 8.

"If 6 grilled cheese sandwiches cost 2x dollars" then 6C= 2x so C= 2x/6= x/3.

"how much will 4 steaks and 2 hamburgers cost?"

One steak cost C+ 8 so 4 steaks cost 4(C+ 8)= 4C+ 32. One hamburger cost C+ 4 so 2 hamburgers cost 2(C+ 4)= 2C+ 8. Together that would be 4C+ 32+ 2C+ 8= 6C+ 40.

Since C= x/3, 4 steaks and 2 hamburgers cost 6(x/3)+ 40= 2x+ 40.

What is the product of 5 1/2 and 3 3/4?

A. 22 3/8

B. 21 1/4

C. 20 5/8

D. 15 3/8

Answers

5 1/2 * 3 3/4 = 165/

= 20 5/

= 20.625

Conversion a mixed number 5 1/

to a improper fraction: 5 1/2 = 5 1/

= 5 · 2 + 1/

= 10 + 1/

= 11/

To find a new numerator:

a) Multiply the whole number 5 by the denominator 2. Whole number 5 equally 5 * 2/

= 10/

b) Add the answer from the previous step 10 to the numerator 1. New numerator is 10 + 1 = 11

c) Write a previous answer (new numerator 11) over the denominator 2.

Five and one half is eleven halfs.

Conversion a mixed number 3 3/

to a improper fraction: 3 3/4 = 3 3/

= 3 · 4 + 3/

= 12 + 3/

= 15/

To find a new numerator:

a) Multiply the whole number 3 by the denominator 4. Whole number 3 equally 3 * 4/

= 12/

b) Add the answer from the previous step 12 to the numerator 3. New numerator is 12 + 3 = 15

c) Write a previous answer (new numerator 15) over the denominator 4.

Three and three quarters is fifteen quarters.

Multiple: 11/

* 15/

= 11 · 15/

2 · 4

= 165/

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(165, 8) = 1. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - eleven halfs multiplied by fifteen quarters is one hundred sixty-five eighths.

What value of y makes the equation true?

3(2y + 3) = 9y - 15

Answers

Answer:

Step-by-step explanation:

First, distribute the 3 on the left side of the equation:

6y + 9 = 9y - 15

Next, move the variables to one side of the equation and the constants to the other:

6y - 9y = -15 - 9

Simplifying the left side:

-3y = -24

Finally, solve for y by dividing both sides by -3:

y = 8

Therefore, the value of y that makes the equation true is 8.

your answer will be y=8
