Ashley paid $11.20 for 5 pears and 6 peaches. The cost of 3 pears is as much as 2 peaches. What is the cost of a pear?

Answer: 15 ounces

Step-by-step explanation:

We need to find the unit rate for each of the prices/ounces,

0.89/10 = 0.089

1.29/15 = 0.086

2.26/18 = 0.125...

3.39/32 = 0.1059375

The answer is:

B. 15 ounces

Because the unit rate(cost per ounce) is 0.086 cents per ounce which is less than:

A. 0.086

C. 0.126

D. 0.106

Answer:

B

Step-by-step explanation:

Answer:

C. [tex]f(x)=\sqrt[3]{-x} -1[/tex]

Step-by-step explanation:

Consider graph of the parent function (red curve in attached diagram)

[tex]g(x)=\sqrt[3]{x}[/tex]

First, multiply it by -1 to get function

[tex]h(x)=-\sqrt[3]{x}[/tex]

Then translate the graph of the function h(x) 1 unit down, then you'll get the function

[tex]f(x)=-\sqrt[3]{x} -1\\ \\ \text{or}\\ \\f(x)=\sqrt[3]{-x} -1[/tex]

The graph of the function f(x) is represented by the blue curve in attached diagram

Answer:

[tex]64.3=\frac{1}{3}(B)(7)[/tex]

Step-by-step explanation:

we know that

The volume of a cone (bird feeder) is equal to

[tex]V=\frac{1}{3}Bh[/tex]

where

B is the area of the base

h is the height of the cone

In this problem we have

[tex]V=64.3\ cm^{3}[/tex]

[tex]h=7\ cm[/tex]

substitute

[tex]64.3=\frac{1}{3}(B)(7)[/tex]

[tex]192.9=(B)(7)[/tex]

[tex]B=192.9/(7)=27.56\ cm^{2}[/tex]

The equation that can be used to determine the area of the circular lid needed to cover the bird feeder is 64.3 = 1/3 x b x 7.

A cone is a three-dimensional shape that consists of a circular base and a vertex.

Volume of a cone = 1/3πr²h

Area of a circle = πr²

πr = 64.3 = 1/3 x b x 7

The area of rectangle C is 2

Step-by-step explanation:

Using a scale factor of [tex]\frac{1}{5}[/tex] yields the side lengths of 1 and 2

[tex](1)(2)=2[/tex]

Answer:

2 square units

Step-by-step explanation:

hello

The scale factor or linear scale factor is the ratio between the length of the same side in two similar figures.

in the graph we have  a rectangle with width 5 units and long 10 units, and we know the scale factor is 1/5

[tex]S_{f}=\frac{width(C)}{width(B)}\\ \\Width(B)*S_{f} =width(C)=5 units *\frac{1}{5} \\\\Width(C) =\frac{5}{5} units =1 unit[/tex]

[tex]S_{f} =\frac{length (C)}{length(B)} \\\\\\length(C)=length(B)*S_{f}\\length(C)=(10*\frac{1}{5})[/tex]

Answer:

The answer would be B. decrease the temperature by 2 degrees Celsius.

Step-by-step explanation:

Since 2°C - 2°C= 0, then you would obviously have to subtract to find your answer.

Answer: D

Step-by-step explanation:

For this case we must find the product of the following expressions:

[tex]\frac {3x} {x + 1} * \frac {x} {x-7}[/tex]

So:

[tex]\frac {3x ^ 2} {x ^ 2-7x + x-7} =\\\frac {3x ^ 2} {x ^ 2-6x-7}[/tex]

So, we have to:

[tex]\frac {3x} {x + 1} * \frac {x} {x-7} = \frac {3x ^ 2} {x ^ 2-6x-7}[/tex]

Answer:

[tex]\frac {3x ^ 2} {x ^ 2-6x-7}[/tex]

Step-by-step explanation:

Using the sine ratio in the right triangle

let the angle be x, then

Answer:

42.5%

Step-by-step explanation:

Answer:

42.5

Step-by-step explanation:

34/80×100/1

=340/8

=42.5

You must use Pythagorean theorem, which is [tex]a^{2} +b^{2} =c^{2}[/tex]

a and b are both legs (the two legs are the sides that form a perpendicular right angle) while c is the hypotenuse (side opposite the right angle)

In this case...

a = y

b = 8

c = 12

^^^Plug these numbers into Pythagorean theorem

[tex]y^{2} +8^{2} =12^{2}[/tex]

Simplify as much as possible

[tex]y^{2}[/tex] + 64 = 144

Isolate y by subtracting 64 to both sides

[tex]y^{2}[/tex] + (64 - 64) = 144 - 64

[tex]y^{2}[/tex] = 80

Further isolate y by taking the square root of both sides. This will take away the square from the left side

y = [tex]\sqrt{80}[/tex]

[tex]\sqrt{80}[/tex] <<< Can be further simplified

4√5 = y

~Just a girl in love with Shawn Mendes

Remember that a complex number has the form a + bi. You need to figure out what a and b need to be. Since −3i is an imaginary number, it is the imaginary part (bi) of the complex number a + bi. This imaginary number has no real parts, so the value of a is 0.

ANSWER

Yes

EXPLANATION

The number

[tex]3i[/tex]

can be rewritten as

[tex]0 + 3i[/tex]This is of ty form

[tex]z = a + bi[/tex]

where 0 is the real part and 3i is the imaginary or complex part.

[tex]3i[/tex]

is therefore a complex number. It is purely imaginary because the real part is zero.

Answer:

C. 0.8125

Step-by-step explanation:

The probability to sell 5 or more DVDs in a day is the complement of the probability of selling less than 5 DVDs in a day, since sales <5 DVDs + sales >= 5 DVDs = 100% of the sales.

So, we know what's the probability of selling less than 5 DVDs in a day is... it's 0.1875

So, to find the possibility of selling 5 or more DVDs in a day, we take 100% of the chances (1.0) and we subtract the probability of selling <5 DVDs in a day:

P = 1.0 - 0.1875 = 0.8125

C. 0.8125 is your answer.

Answer: OPTION C.

Step-by-step explanation:

Given a function f(x), the range of the inverse of f(x) will be the domain of the function f(x) and the range of the domain of f(x) will be the range of the inverse function.

For example, if the point (2,1) belongs to f(x), then the point (1,2) belongs to the inverse of f(x).

Observe that in the graph of the function f(x) the point (-3,1) belongs to the function, then the point (1,-3) must belong to the inverse function.

Therefore, you need to search the option that shown the graph wich contains the point (1,-3).

Observe that the Domain f(x) is (-∞,0) then the range of the inverse function must be (-∞,0).

This is the graph of the option C.

You may consider a function with domain [tex](0,\infty)[/tex] and switch [tex]x\mapsto -x[/tex]

For example, we know that

[tex]y=\log(x)[/tex]

can only be evaluated for positive values of the argument. This means that

[tex]y=\log(-x)[/tex]

can also be evaluated only for positive values of the argument, i.e.

[tex]-x>0 \iff x<0 \iff x \in (0,\infty)[/tex]

To give another example, you may consider a function with domain [tex][0,\infty)[/tex], consider its inverse to remove 0 from the domain, and finally switch again [tex]x\mapsto -x[/tex]:

[tex]\sqrt{x} \implies D = [0,\infty)\\\dfrac{1}{\sqrt{x}} \implies D = (0,\infty)\\ \dfrac{1}{\sqrt{-x}} \implies D = (-\infty,0)[/tex]

The angle of 110° and the angle labelled as 1 form 180°, so we have

[tex]<1> = 180-110=70[/tex]

The same holds for the angle labelled 2 and the 115° angle:

[tex]<2> = 180-115=65[/tex]

Angle 1, 2 and 7 are the interior angles of a triangle, so they sum to 180. We can deduce

[tex]<7> = 180-70-65=45[/tex]

Angles 5 and 7 are corresponding angles, so they have the same measure.

Answer:  13

Step-by-step explanation:  1st - Distribute the -1 through to the x + -1*(5+x) first:  8 + -1*[x + -1*(5+x)] = 8 + [-1*x  +  -1*-1*(5+x)]

= 8 + [-x + -1*-1 *(5+x)]

Multiply the two -1s that are in front of the (5+x).  Negative x Negative = positive

Minus the paranthesis

Do PEDMAS

8 + [-x + 5 + x]  <- -x +x = 0

                = 8 + [0 + 5]  <- 0 and 5 are like terms and will be combined

                = 8 + 5 = 13

His sister is 8 and he is 20.

let's say z represents liz. we can make an equation where z+12=4z.

Solve for that and z is equal to 4. Now that was 4 years ago. She should be 8 now?

I hope this is correct because my brain isn't doing so well today.

Answer:

Adam is 20 years old and Liz is 8 years old.

Step-by-step explanation:

Let present age of Adam = x years

Let present age of Liz = y years

Now we will make the equations.

x = y + 12 -------------(1)

For second equation

( x-4) = (y-4) × 4

x-4 = 4y - 16

x = 4y + 4 - 16

x = 4y - 12 -----------------(2)

By substitution method, we  substitute  the value of  x  from equations (1) to equation (2).

y + 12 = 4y - 12

y - 4y + 12 = -12

-3y = -12 -12

3y = 24

y = 8

Now we put the value of y in equation (1)

x = 8 + 12 = 20

Therefore, Adam is 20 years old and Liz is 8 years old.

-Hello There-

ANSWER: 10 Is 40% Of 25

EXPLANATION

What is 40% of 25?

Y is 40% of 25

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 40% * 25

Converting percent to decimal:

p = 40%/100 = 0.4

Y = 0.4 * 25

Y = 10

Answer:

Step-by-step explanation:

Look at the picture.

It's a net of right rectangular prism.

We have three pairs of rectangles:

7ft × 8ft

7ft × 18ft

8ft × 18ft

The formula of an area of a rectangle l × w:

A = lw

Calculate the areas:

A₁ = (7)(8) = 56 ft²

A₂ = (7)(18) = 126 ft²

A₃ = (8)(18) = 144 ft²

The Surface Area :

S.A. = 2A₁ + 2A₂ + 2A₃

Substitute:

S.A. = 2(56) + 2(126) + 2(144) = 652 ft²
