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.

A. 22 3/8

B. 21 1/4

C. 20 5/8

D. 15 3/8

Answers

C:

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

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

2

= 5 · 2 + 1/

2

= 10 + 1/

To find a new numerator:

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

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.

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.

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.

A designer creates a drawing of a triangular sign on centimeter grid paper for a new business. The drawing has sides measuring 6 cm, 8 cm, and 10 cm, and angles measuring 37°, 53°, and 90°. To create the actual sign shown, the drawing must be dilated using a scale factor of 50.

Part 1 out of 4
Find the lengths of the sides of the actual sign.
__ cm, ___ cm, ___ cm

Answers

Answer:
The actual length is 6*40=240 cm, 8*40=320 cm, 10*40=400 cm. And the angle measures of the actual sign will not change. The transformation can be turning over using the hypotenuse as axle. Or rotate the triangular sign 180° using the center of the triangle as the center of rotation. The turning over method will accomplish.

paulo used clay to make the cube shown.he wants to make a larger cube with an edge length that is twice as long.how many ounces of clay does he need to make this larger cube?

Answers

Answer:

8 times more clay than the original cube

Step-by-step explanation:

There's no picture here so I'll say it variably. If the original cube has side length [tex]x[/tex], then the amount of clay needed is [tex]x^3[/tex] because the formula for volume of a cube is [tex]v=s^3[/tex]. Similarly, a cube with side lengths twice as long would have a side length of [tex]2x[/tex]. The volume of this new cube would be[tex](2x)^3=8x^3[/tex], 8 times the volume of the original cube.

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 value of y makes the equation true?

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

Answers

Answer:

8

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

Write the prime factorization of 1008 and 1323. Then
reduce 1008/1323

Answers

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.

Read the passage. The Lyme Mystery In the mid-1970s, doctors were baffled when residents of Lyme, Connecticut, and neighboring towns developed a set of strange symptoms, including leg pain, swollen joints, and rashes. Suspecting a reason beyond mere coincidence, a Yale University research team systematically reviewed the cases. They discovered that all the victims had lived in wooded areas and that disease outbreaks had peaked in the summer and early fall, suggesting a connection to an insect. In addition, the number of cases occurring east of the Connecticut River outnumbered those occurring on the west side. This information led to the hypothesis that the mysterious condition was related to deer ticks, since deer and the black-legged ticks they carry were more prevalent on the east side of the river. Later research proved this hypothesis correct. The black-legged tick was found to carry bacteria that, when transmitted to humans through bites, cause the condition now known as Lyme Disease. What is the main idea of the passage? Researchers discovered that a strange illness was caused by bacteria in the bite of the black-legged tick. Because many victims lived in wooded areas, researchers suspected that a strange illness was caused by an insect. Researchers discovered that a strange illness was more common east of the Connecticut River than west of it.
