What solid 3D object is produced by rotating the quarter-circle about line m

Answer:

so, you've lost 14.7 percent of value. or, in other words, you still have 85.3 percent of value.

Step-by-step explanation:

so just so .853 times 128 and you're there I'm too lazy to grab calc but please give me brainliest answer

Answer: $109

Step-by-step explanation:

Given stock at last year = $128

14.7 percent decrease = 14.7/100 × 128

=$18.8

To get the Current worth of stock, we then subtract 14% decrease from the worth of stock as at last year:

= $128 - $18.8

=$109.18 to the nearest cent is $109

Answer:

y = -3/4x + 5

Step-by-step explanation:

Slope intercept form is y=mx + b

First, find the slope of the line. the points are (0,5) and (4,2), as marked. To find the slope, you do (y2-y1)/(x2-x1). Fill in the numbers and you get

(2-5)/(4-0). Simplify and you get -3/4 is the slope. Then, to find b, you have to fill in one coordinate pair and the slope into y=mx+b. So, I used (0,5).

5=(-3/4)(0) + b

Then you get 5=b by solving, and you fill in the slope and the y intercept in the slope intercept form equation. y = -3/4x +5. This is how you find the answer.

The value of x is 13°.

Solution:

In triangle, sum of all the interior angles = 180°

m∠A + m∠B + m∠C = 180°

(3x)° + (4x – 1)° + 90° = 180°

3x° + 4x° – 1° + 90° = 180°

7x° + 89° = 180°

Subtract 89° from both sides of the equation, we get

7x° = 91°

Divide by 7 from both sides of the equation, we get

x° = 13°

The value of x is 13°.

Answer:  Furniture over weeks

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

So, for the function f (w(h)) = hours /week x (furniture /hours)

Because "hours" are in both terms, and one is the numerator and the other is the denominator, they can be cancelled with each other.

f (w(h)) = furniture / week

Mariko caught 10 rockfish and 14 bluefish on her fishing trip.

Let's define the number of rockfish caught as x and the number of bluefish caught as y.

According to the given information, the average weight of each rockfish is 2.5lbs and the average weight of each bluefish is 8lbs.

We can form two equations based on the total weight of all the fish and the total number of fish caught:

We can solve this system of equations to find the values of x and y by either substitution or elimination method. Using the elimination method:

Multiplying Equation 1 by 2.5, we get 2.5x + 2.5y = 60

Subtracting this equation from Equation 2, we get 8y - 2.5y = 137 - 60

Simplifying, we have 5.5y = 77

Dividing both sides by 5.5, we get y = 14

Substituting this value back into Equation 1, we have x + 14 = 24

Simplifying, we get x = 10

Therefore, Mariko caught 10 rockfish and 14 bluefish.

Reduce the expression by cancelling the common factors.

The correct answer is A.

Answer:

No.

Step-by-step explanation:

3/4 cannot be simplified. Neither can 7/8. Also, 3/4 as a decimal is 0.75, and 7/8 as a decimal is 0.875.

Answer:

No

Step-by-step explanation:

Is 3/4 less than 7/8? Is 3/4 smaller than 7/8? These are the same questions with one answer.

To get the answer, we first convert each fraction into decimal numbers. We do this by dividing the numerator by the denominator for each fraction as illustrated below:

3/4 = 0.75

7/8 = 0.875

Then, we compare the two decimal numbers to get the answer.

0.75 is less than 0.875.

Therefore, 3/4 is less than 7/8 and the answer to the question "Is 3/4 less than 7/8?" is yes.

The inequality is d<-80 since the problem states you go deeper than -80 feet.

As for graphing the inequality, you use a open circle with the arrow pointing left.

<= means closed

>= means closed

< means open

> means open

Answer:

Question:  You need to figure out the inequality. Here is the full question: On their first dive, scientists explore a part of the ocean floor that is 80 feet below sea level. This depth can be represented by the integer -80. On their second dive, they explore a deeper depth. Write an inequality that represents the possible depth, d, of the scientist's second dive. After you figure that out you can answer the question above.

d < -80

option c {(0, -5), (2,9), (-3, -26)}  is correct  . All others doesn't satisfy the equation .

Step-by-step explanation:

We have , If y = 7x - 5, following set of ordered pairs {(0, -5), (2,9), (-3, -26)} . Let's check for this

(0, -5):

⇒ [tex]y = 7x-5[/tex]

⇒ [tex]y = 7(0)-5[/tex]

⇒ [tex]y =-5[/tex]

So , it's correct ordered pair .

(2,9):

⇒ [tex]y = 7x-5[/tex]

⇒ [tex]y = 7(2)-5[/tex]

⇒ [tex]y =9[/tex]

So , it's correct ordered pair .

(-3,-26):

⇒ [tex]y = 7x-5[/tex]

⇒ [tex]y = 7(-3)-5[/tex]

⇒ [tex]y =-26[/tex]

So , it's correct ordered pair .

Therefore, option c {(0, -5), (2,9), (-3, -26)}  is correct  . All others doesn't satisfy the equation .

The speed is the distance covered by an object at a particular time. The speed of bus B is 70 miles per hour.

The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.

[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]

Given that Bus A can travel 125 miles in 3 hours. While Bus B can travel 85 more miles than bus A within the same time. Therefore, we can write,

Distance traveled by Bus B = 125 miles + 85 miles = 210 miles

Time is taken by Bus B = 3 hours

Now, the speed of the bus B can be written as,

Speed of Bus B = Distance Covered / Time taken

                          = 210 miles / 3 hours

                          = 70 miles per hour

Hence, the speed of bus B is 70 miles per hour.

It will take approximately 1.5 hours for the snowfall in both towns to be equal.

The question asks to determine when the snowfall in two different towns will be equal. The first town starts with 2 inches of snow and accumulates 6 inches every hour. The second town starts with 8 inches of snow and accumulates 2 inches every hour. To find when the depths will be equal, we need to set up an equation where the snow depths of both towns are set equal to each other and then solve for time (t).

Let t be the number of hours required for the snow depths to be equal.

For the first town: Initial depth + (Rate of snowfall * Time) = 2 inches + (6 inches/hour * t)

For the second town: Initial depth + (Rate of snowfall *Time) = 8 inches + (2 inches/hour *t)

Setting both expressions equal, we get: 2 + 6t = 8 + 2t. By solving for t, we subtract 2t from both sides and also subtract 2 from both sides to obtain: 4t = 6. Then we divide both sides by 4 to find t = 1.5 hours.

So, it will take 1.5 hours for the snow depths in both towns to be equal.

The number of fiction books is 18.

Ratio expresses the relationship between two values. It is the number of times that one value is contained within other value(s).

Number of books = (number of mystery books x sum of ratios) / ratio of mystery books

90 calories in total

Step-by-step explanation:

We can solve this equation through the following steps:

Step One: Since we are told that a banana is 20 less calories than an orange, we can create the Let Statements:

Let x= the calories in a banana

Let x-20=the calories in an orange

Step Two: Create an equation

Since we are told "7 bananas have the same calories as 9 oranges" we translate"

7x=9(x-20) Distribute

7x=9x-180 Subtract 9x from both sides of the equation

7x-9x=-180 Simplify

-2x=180 Divide both sides by -2

x=90

∴There are 90 calories in a banana.

Answer:

I'm assuming the equation is:

2x^2 -10x +7 = 0

x = (-b +- sqr root (b^2 - 4ac)) / 2a

x = (--10 +-sqr root (100 -4*2*7)) / 4

x = (10 +- sqr root (44)) / 4

x1 = (10 + 6.6332495807 ) /4

x1 = 16.6332495807 / 4

x1 = 4.1583123952

x2 =(10 - 6.6332495807 ) /4

x2 = 3.3667504193  / 4

Answer:

I think it's $12.80 but I might be wrong.

Each person will have to contribute $6.40.

To find out how much money each person will have to contribute to get to the university and back, we can first find the total cost of the trip. The distance to the university and back is 2 times the distance to the university, which is 105 miles. So the total distance is 2 * 105 = 210 miles. Roberta's car can travel 8.2 miles per dollar of gasoline, so the total cost of the trip is 210 / 8.2 = 25.61 dollars. Since Roberta and three friends are splitting the cost evenly, each person will have to contribute 25.61 / 4 = 6.4025 dollars. Rounding to the nearest cent, each person will have to contribute $6.40.
