Answer:

1/2 pi

Step-by-step explanation:

This is 1/4 of a circle

Find the  circumference and multiply by 1/4

1/4 C

1/4 ( 2*pi*r)  where r is the radius

The radius is 1

1/2 pi*1

1/2 pi

Answer:

Step-by-step explanation:

A full circle has a circumference of 2*pi * r

r = 1

so Full Circle = 2 * PI

1/4 Circle = 2*pi / 4 = 1/2 pi

The length of the arc length = 1/2 pi

Just in case you prefer the more numerical answer, 1/2 * 3.14 = 1.57

Answer:

Let the height of the larger box = h

and length and width of the larger box = l and w , repectively

Now , Let find the volume of the larger box

Volume = length * width * height

So Volume of the larger box = l*w*h = lwh

Now the question says

the height of the smaller box is 80% of the height of the larger box

It means

Height of the smaller box = 80% of h = 0.80*h = 0.80h

and the other two dimensions are same so it means length and width of the smaller box = l and w

so, Volume of the smaller box = l*w*0.80h = 0.80lwh

So the Difference in the volume of the two boxes = Volume of larger box - Volume of smaller box

therefore , Difference in the Volume of two boxes = lwh - 0.80 lwh = 0.20lwh

Answer:

(10,0)(-1,0)

Step-by-step explanation:

x^2 - 9x - 10 = 0

(x - 10)(x + 1) = 0

The two solutions are

x - 10 = 0

x = 10

or

x+1 = 0

x = - 1

Answer:

x=10, x=-1

Step-by-step explanation:

Hi there!

We are given this equation:

x²-10=9x

And we want to solve it by factoring

Factoring is easier to do when all of the terms are on the same side, so let's subtract 9x from both sides

x²-9x-10=0

Now we must think of two numbers that add up to -9, but multiply to get -10

Those numbers are -10 and 1

So factor the polynomial using FOIL:

(x-10)(x+1)=0

Now split and solve via the zero product property:

x-10=0

Add 10 to both sides

x=10

x+1=0

Subtract 1 from both sides

x=-1

Step-by-step explanation:

"Perry saved 4 twenty-dollar bills, 2 ten-dollar bills, 3 dimes, and 2 pennies."

4 * 20 = 80

2 * 10 = 20

3 * 0.1 = 0.3

2 * 0.01 = 0.02

80 + 20 + 0.3 + 0.02 = $100.32

100.32 - 49.86 = 50.46

Hope this helps you.

Answer:

$50.46

Step-by-step explanation:

Answer:

50/3

Step-by-step explanation:

area of triangle = 10

area of circle = 10

area of triangle + area of circle = 20

The white sector of the circle has central angle 60°.

Its area is 1/6 the area of the circle.

To find the gray area, you must subtract the white area from the area of the circle and also subtract the white area from the area of the triangle. Two times the white area is 1/3 the area of the circle.

gray area = 20 - (1/3)10

gray area = 20 - 10/3

gray area = 60/3 - 10/3

gray area = 50/3

Answer:

The white sector of the circle = (1/6) (10) = 10/6 = 5/3

So....the grey area = 10 + 10 - 2 (5/3) = 20 - 10/3 = 60/3 - 10/3 = 50 / 3

Answer:   -12 - 3 = -15

Explanation:

We start at -12 which goes in the first box.

Moving to the left 3 units means we subtract off 3, so that's why 3 goes in the second box.

The arrow is pointing at -15 as the final destination, which goes in the final third box.

The equation to find the nth term is:

an = a+(n-1)d

Where a is the first term in the sequence, which is 1 and d is the difference, which in this sequence the next term is found by adding 2 to the previous term, so d = 2 and n is the term you want to find.

The equation is:

an = 1 + (n-1)2

a24 = 1 + (24-1)2 = 1 + 23(2) = 1+46 = 47

Answer:

The answer to this question is letter C

We can approach this by first finding the rate of feet per second traveled.

240(feet)/30(seconds)= 8 feet per second.

This answer resembles the slope for answer choice C.

Answer:

-3r + 15 ---> answer

Step-by-step explanation:

r < 5

You are going to multiply both sides with 3. The reason being is that 3 is a positive number and the equality sign will not change if you use +3.

3r < 15

Now, subtract 15 from both sides, you will get this:

3r < 15

-15   -15

-------------

3r — 15 < 0

Lastly, using the Modulus function, we are going to add a negative sign to the content of our previous step because it's already negative.

So, -3r + 15 is the final solution if r < 5 in the given equation of l3r-15l

Answer:

C = 15m

Step-by-step explanation:

Since the almonds are $15 per kg, the cost can be represented by 15m, where m is the number of kg.

To create the equation, set this equal to C, the cost in dollars:

C = 15m

So, the equation is C = 15m

Here is an equation to represent the relationship between the cost, C, in dollars, and the mass, m, in kg of almonds sold at a rate of $15 per kg at a local store: C = 15m

The mass of the almonds closely relates to how much they cost. This implies that the price of almonds will rise along with the mass of the nuts. Since the proportionality constant is $15, the price will be $15 for every kilogram of almonds.

Let's use an illustration to try to comprehend this. A 2 kg purchase of almonds will cost $30. Since 2 x 15 = 30, this is the case.

Answer:

140

Step-by-step explanation:

The prism shown is a rectangular prism

Volume of a rectangular prism = length * width * height

Given length: 3 1/2

Given width: 5

Given height: 8

Volume = 3.5 * 5 * 8 = 140

Answer:

[tex]A=140[/tex]

Step-by-step explanation:

The volume of a three-dimensional object is the amount of space the object takes up. In this case, the prism is a rectangular  prism, its volume can be found using the following formula,

[tex]A=l*w*h[/tex]

Substitute the given values into this formula,

[tex]A=l*w*h[/tex]

[tex]A=8*5*3\frac{1}{2}[/tex]

Simplify,

[tex]A=8*5*3\frac{1}{2}[/tex]

[tex]A=40*3\frac{1}{2}[/tex]

Convert the mixed number into an improper fraction, this can be done by multiplying the "number" part of the mixed number by the denominator (number under the fraction bar). Then one adds the result to the numerator (number over the fraction bar).

[tex]A=40*3\frac{1}{2}[/tex]

[tex]A=40*\frac{(3*2)+1}{2}[/tex]

[tex]A=40*\frac{6+1}{2}[/tex]

[tex]A=40*\frac{7}{2}[/tex]

To simplify further, one must divide the number the fraction is being multiplied by the denominator of the fraction,

[tex]A=40*\frac{7}{2}[/tex]

[tex]A=20*7[/tex]

Multiply to finish simplifying and get the answer,

[tex]A=20*7[/tex]

(3,2) isn’t a solution because it doesn't satisfy the equation also, the line on the graph doesn’t go through it .

We do same operations on both the sides so that equality of both expressions doesn't get disturbed.

Solving equations generally means finding the values of the variables used in it for which the considered equation is true.

The graph of the equation is given as y = -3/4x + 3.

We have to find if the point (3, 2) a solution to the equation.

So, we will subtitute the point to to satify the equation;

y = -3/4x + 3.

y = -3/4(3) + 3

y = -9 / 4 + 3

y = 3/3 = 1

Thus, (3,2) isn’t a solution because it doesn't satisfy the equation also, the line on the graph doesn’t go through it .
