Answer:

ok one doll is 3 dollars and one purse is 6 dollars

and for the bottom I got 84 so I don't know I'm sorry

Step-by-step explanation:

Answer:

1. The unit price for a doll is three dollars. The unit price for a purse is six dollars.

2. One doll costs three. One purse costs six.

3. Polly spends $24 on the 2 dolls and 3 purses.

Step-by-step explanation:

Doing some calculations, 1 doll costs three dollars and 1 purse costs six dollars.

5 x 3 + 6 = 21

7 x 3 + 1  = 27

If Polly buys 2 dolls and 3 purses, that means she spends six dollars on the dolls and eighteen dollars on the purses.

(2 x 3) + (3 x 6) = $24

Polly spends $24 on 2 dolls and 3 purses.

She has 1 61/152 pounds of apples left

Fractions are represented as numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing

In order to find how many pounds of apples she has left, subtract the apple she sold from the apple she begins with. That is:

Apple left = 35 1/2 - (35 1/2 * 1/2) - (35 1/2 *4/19) - (35 1/2 * 1/4 )

Apple left = 1 61/152

The total value of the loan with the quarterly compounded interest

is $117599.

Borrowers are required to pay interest on interest in addition to principal since compound interest accrues and is added to the accrued interest from prior periods.

A = P(1 + r/100)ⁿ.

[tex] \frac{6}{20} \times 60[/tex]= 18 miles/hour

Next, let's compare this speed to the 9 miles per ½ hour:

The equation can be used to solve for x is 90-52 = (12x - 10)°

Angle geometry is a branch of mathematics that deals with the study of angles and their properties in two-dimensional figures such as circles, triangles, and polygons.

In the diagram, since vertically opposite angles are equal. Thus, we can say:

∠UTW =  ∠VTZ

90 - 52 = (12x - 10)°

38 = 12x - 10

12x = 38 + 10

12x = 48

x = 48/12

x = 4

Therefore, the equation is 90-52 = (12x-10)°

The requried area of 3 of the pieces is 231 square feet. Option B is correct.

The area of a circle is the amount of space enclosed by the circle in a two-dimensional plane. It is given by the formula:

A = πr²

where "A" is the area of the circle, "r" is the radius of the circle, and "π" (pi) is a mathematical constant with an approximate value of 3.14159.

Here,
The area of a full circle with a radius of 14 feet is given by:

A = πr²

A = (22/7) × (14)²

A = (22/7) × 196

A = 616 square feet (rounded to the nearest whole number)

If the circle is cut into 8 equal pieces, each piece will have an area of:

616 ÷ 8 = 77 square feet

Therefore, 3 pieces will have an area of 3 × 77 = 231 square feet.

Thus, the requried area of 3 of the pieces is 231 square feet. Option B is correct.

Answer:

8.  TN = 22 units

9.  RT = √(165) units

Step-by-step explanation:

It appears that point T is the circumcenter of triangle MNP.

A circumcenter of a triangle is:

As a perpendicular bisector is a line that divides another line segment into two equal parts at a right angle, then:

As point T is the circumcenter, ΔMTN, ΔNTP and ΔMTP are isosceles triangles and MT, TP and TN are the radius of the circumcircle.

Therefore:

To find the length of TN, find the value of x by equating the given expressions for MP and TP:

[tex]\implies \sf MT = TP[/tex]

[tex]\implies 6x - 56 = 3x - 17[/tex]

[tex]\implies 3x = 39[/tex]

[tex]\implies x = 13[/tex]

Substitute the found value of x into the expression for TP:

[tex]\implies \textsf{TP} = 3(13) - 17[/tex]

[tex]\implies \textsf{TP} = 22[/tex]

Therefore, as TN = TP then TN = 22 units.

First find the value of x by equating the given expressions for TN and TP:

[tex]\implies \sf TN=TP[/tex]

[tex]\implies 4x-17=x+10[/tex]

[tex]\implies 3x=27[/tex]

[tex]\implies x=9[/tex]

Substitute the found value of x into the expression for TN:

[tex]\implies \textsf{TN} = 4(9) - 17[/tex]

[tex]\implies \textsf{TN} = 19[/tex]

As RT is the perpendicular bisector of MN, then ΔTRN is a right triangle where ∠TRN is 90°.

Given:

To calculate the length of RT, use Pythagoras Theorem:

[tex]\implies \sf RN^2+RT^2=TN^2[/tex]

[tex]\implies \sf RT=\sqrt{TN^2-RN^2}[/tex]

[tex]\implies \sf RT=\sqrt{19^2-14^2}[/tex]

Answer:

Step-by-step explanation:

let x = length of a side of the cube

all sides are equal in a cube

Volume = x³ = 1000 cm³

x = ∛1000 = 10 cm

Area of 1 side = 10cm x 10cm = 100 cm²

There are 6 equal sides in a cube

SA = 6(100) =  600 cm²

The length of the side D'E' is 9 units for the given translated triangle D'E'F'.

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

As we know that the translation does change the change location but it can't change the shape of the figure.

According to the given question, triangle DEF is translated as 6 units right and 6 units up.

This means there are no changes in the dimensions.

So D'E' =  DE

Thus, D'E' = 9 units

√(3−0)2+(4−0)2=√9+16=√25=5

The dimensions that will maximize the enclosed area are 125 meters by 250 meters

Represent the dimensions with x and y

So, we have the following equations

Perimeter = 4x + 2y = 1000

Area = 2xy

So, we have

2x + y = 500

This gives

y = 500 - 2x

So, we have

Area = 2x(500 - 2x)

Expand

Area = 1000x - 4x^2

Differentiate and set to 0

1000 - 8x = 0

So, we have

8x = 1000

Divide

x = 125

Recall that

y = 500 - 2x

y = 500 - 2 * 125

y = 250
