Answer: 11

Step-by-step explanation:

i did 3.5 x 3.14 = 10.99 and rounded to the nearest whole number, 11.

The circumference of the circular window to the nearest whole number is 11 feet.

A circle is a two-dimensional figure with a radius and circumference of 2pir.

The area of a circle is pir^2.

We have,

To find the circumference of the circular window, we need to use the formula:

C = πd

where C is the circumference, π is the constant pi, and d is the diameter of the circle.

Since the window is 3.5 feet across at its widest point, the diameter of the circle is also 3.5 feet.

Plugging in the value of the diameter in the formula, we get:

C = πd

C = 3.14 x 3.5

C = 10.99

Rounding the result to the nearest whole number, we get:

C ≈ 11 feet

Therefore,

The circumference of the circular window to the nearest whole number is 11 feet.

Answer:

147) B

148) D

Step-by-step explanation:

_____________________145_____________________

Starting with number 145 it mentions that XY = 24 and XY:YZ = 1:2.

XY:YZ means ratio of XY over YZ so for each 1 XY there is 2 YZ.

Moving on and taking note that XY=24 so this means that,

[tex]\frac{XY}{YZ} =\frac{24}{YZ}= \frac{1}{2}[/tex]

Solving the above expression by cross multiplying 24x2 will give you YZ = 48. The same method applies to #146 and #148 the next questions.

_____________________146_____________________

YZ = 9 and XY:YZ=2:3

[tex]\frac{XY}{YZ} =\frac{XY}{9} =\frac{2}{3}[/tex]

XY= (2x9)/3 = 6

XY = 6

_____________________147_____________________

Given:

XZ = 2ft

YZ = 18in

In this question, you will have to refer to the proportion line given above the questions. It mentions that XZ = 2ft (which is the whole line) and YZ = 18in (which is from Y to Z). Take note that the units are not the same.

They're looking for XY which is the only unknown length in the given proportion line. To get XY you'll have to subtract XZ - YZ, but the units are not the same so you'll have to convert feet to inches since the answer options are given in inches.

Convert 2ft to inches:

To convert from feet to inches you'll have to multiply by 12 so 2x12 = 24.

Therefore, XZ = 24in

Now we subtract:

XZ - YZ = XY

24 - 18 = 6in

_____________________148_____________________

YZ = 1ft

XY: YZ = 1:4

YZ is given in feet and the answers are provided in inches so we'll have to convert.

1 x 12 = 12in

YZ = 12in

[tex]\frac{XY}{YZ} =\frac{XY}{12} =\frac{1}{4}[/tex]

XY = (1x12)/4 = 3in

Answer:

One solution

Step-by-step explanation:

In a one- variable equation has infinitely many solutions when solving results in a true statement, such as 2=2

In a one- variable equation has one solution when solving results in one value for the variable, such as x = 5

In a one - variable equation has no solution when solving results in an untrue statement, such as 2=3

So, in this case the result x = -2 belongs to the 2nd sentence where it says one solution.

11 divided by 5 is equal to the fraction 11/5, which can also be expressed as the mixed number [tex]2\frac{1}{5}[/tex] .

To convert the division of 11 by 5 into a fraction, we can express it as a ratio of two integers. Here's how we can derive the fraction:

When we divide 11 by 5, we get a quotient of 2 with a remainder of 1. So, we can write the division as:

11 ÷ 5 = 2 + 1/5

Since 2 is a whole number, we can express it as a fraction with a denominator of 1:

2 = 2/1

Now, we can rewrite the division using the same denominator:

11/5 = 2/1 + 1/5

To combine the fractions, we need a common denominator. The least common multiple (LCM) of 1 and 5 is 5. Therefore, we can multiply the fractions by appropriate values to make their denominators equal to 5:

11/5 = (2/1) × (5/5) + (1/5) = 10/5 + 1/5

Now that the denominators are the same, we can add the fractions:

11/5 = (10 + 1)/5 = 11/5

Therefore, the division of 11 by 5 can be expressed as the fraction 11/5.

The fraction 11/5 represents the result of dividing 11 into 5 equal parts. Each part would be equal to 11/5. It can also be simplified to a mixed number as 2 1/5, where the whole number part is 2 and the fractional part is 1/5.

So, 11 divided by 5 is equal to the fraction 11/5, which can also be expressed as the mixed number 2 1/5.

Answer:

1200 miles apart for the two cities

Answer:

59

Step-by-step explanation:

The diagonals of an isosceles trapezoid are equal.

MO and NP are diagonals.  Therefore MO = NP

12y - 37 = 5y + 19

7y = 56

y = 8

MO = 12(8) - 37 = 96 - 37 = 59

NP = 5(8) + 19 = 40 + 19 = 59

7 units are the measurement of the segment NP.

In Mathematics, a polygon can be defined as a two-dimensional geometric figure that consists of straight line segments and a finite number of sides. Additionally, some examples of a polygon include the following:

• Triangle

• Quadrilateral

• Pentagon

• Hexagon

• Heptagon

• Octagon

• Nonagon

Generally speaking, the measure of the angle at the center of a regular polygon is equal to 360 degrees. Therefore, the smallest angle of rotation that maps (carries) a regular polygon onto itself can be calculated by using this formula:

α = 360/n

Since MNOP is an isosceles trapezoid, the non-parallel sides MN and OP have the same length. Therefore, we can set up an equation using the given lengths of the sides:

MP = NO

Substituting the given expressions for these lengths, we get:

16x - 13 = 9x + 8 + 5y + 19

Simplifying and rearranging terms, we get:

7x - 5y = 36 ........(1)

Similarly, we can set up another equation using the given lengths of the diagonals MO and PN:

MO + PN = MP + NO

Substituting the given expressions for these lengths, we get:

12y - 37 + 5y + 19 = 16x - 13 + 9x + 8

Simplifying and rearranging terms, we get:

17y - 16x = 42 ........(2)

Now, we have two equations (1) and (2) with two variables (x and y). Solving this system of equations, we get:

x = 7, y = 9

Substituting these values back into the given expressions for PN and NO, we get:

PN = 5y + 19 = 5(9) + 19 = 64

NO = 9x + 8 = 9(7) + 8 = 71

Therefore, the measure of segment NP is:

NP = NO - PN = 71 - 64 = 7

So, the measure of segment NP is 7 units.

Answer:

circumference = 97.34

Step-by-step explanation:

circumference = diameter x Pi

31 x 3.14 = 97.34 inches

The circumference of the circle with a diameter of 31 inches is approximately 97.34 inches.

The circumference of a circle can be calculated using the formula C = πd, where C represents the circumference and d represents the diameter of the circle.

Given that the diameter of the circle is 31 inches, we can substitute this value into the formula:

C = 3.14 * 31

C ≈ 97.34 inches

Therefore, the circumference of the circle with a diameter of 31 inches is approximately 97.34 inches.

Answer:

1 1/8 inches.

Step-by-step explanation:

As the sails are similar,  corresponding sides are in the same ratio, so we have the equation

:24/3 = 9/b     where  b = base of the souvenir boat.

Cross multiply:

24b = 9*3

b = 27/24

= 1 1/8 inches.

Based on the shape of the souvenir and dimensions of boat, the base of the souvenir's sail is 1.125 inches

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

WE need to find the base of the souvenir sail.

Given that sail on the souvenir boat has the same shape as the sail on the sailboat. Which means that; they can be used to find each other's dimensions based on a scale factor.

The height of the sailboat = 24 feet.

The height of the souvenir boat's sail = 3 inches.

The scale is:

= 24 / 3

= 8

Then for every inch on the souvenir boat's sail, the sailboat is 8 feet.

The base of the souvenir boat sail;

= 9 / 8

= 1.125 inches

Hence, Based on the shape of the souvenir and dimensions of boat, the base of the souvenir's sail is 1.125 inches

Answer: Tom's average speed for the rest of the journey = 48mph

Step-by-step explanation:

Total distance driven = 200 miles

total time taken = 4hours

first 32 miles , he drove at an average speed of 64mph, To find the amount of time taken for the first 32 miles,

We Use the formulae

Speed = distance / time

Time = Distance / speed

=32/64 = 1/2 =0.5 hours

The remaining distance = Total distance covered - first 32 miles covered

= 200 -32= 168 miles

The remaining time for rest of journey = Total time taken - time covered in the first 32miles

4hours - 0.5 hours

=3.5 hours

Therefore Average speed for the rest of the journey = Distance for the remaining journey/  remaining time

168miles/ 3.5hours = 48mph
