Answer:

54.88cm

Step-by-step explanation:

For shaded region perimeter, subtract the circle perimeter from the rectangle

perimeter

= (10*8) - (2 * 3.14 * 8/2)

= 80 -  25.12

= 54.88cm

Answer:

1/5

Step-by-step explanation:

Use Pythagoras theorem

Answer:

The scale factor would be -5.

Step-by-step explanation:

If the driveway is 20 feet but 4 foot on the canvas. Then 20/4 is 5. But since the width is going from 20 to 4, the numbers are going down to it would be a negative scale factor. If it was going from 4 width to 20 width, the scale factor would be a positive 5.

i think the answer is 87.82

Answer:

A = 33.6 sq units

Step-by-step explanation:

A (trapezoid) = 1/2(4)(14+2) = 2(16) = 32

A (semi-circle) = π(1)/2 = 1.57

Answer:

130 maybe

Step-by-step explanation:

Answer:

120

Step-by-step explanation:

It is 120 because if you do 20% of 150 that's 30 so subtract that with 150 leaving you 120.

Given:

Drawing a vowel from letter tiles that spell out MATHEMATICS.

Chances = [tex]\dfrac{?}{?}[/tex]

To find:

The correct values for the blanks.

Solution:

Vowels are a, e, i, o, u.

In MATHEMATICS, the vowels are A, E, A, I.

Number of vowels = 4

We know that,

[tex]Probability=\dfrac{\text{Number of selected vowels}}{\text{Total number of vowels}}[/tex]

[tex]Probability=\dfrac{1}{4}[/tex]

So, the chance of drawing a vowel from letter tiles that spell out MATHEMATICS is [tex]\dfrac{1}{4}[/tex].

Blank 1: 1

Blank 2: 4

Therefore, the value for blank 1 is 1 and the value for blank 2 is 4.

Given:

The given expression is:

[tex]\dfrac{3.6\times 10^7}{7.2\times 10^7}[/tex]

To find:

The value of the quotient.

Solution:

We have,

[tex]\dfrac{3.6\times 10^7}{7.2\times 10^7}[/tex]

It can written as:

[tex]=\dfrac{3.6}{7.2}\times \dfrac{10^7}{10^7}[/tex]

[tex]=\dfrac{1}{2}\times 1[/tex]

[tex]=0.5[/tex]

It can be rewritten as:

[tex]=5\times \dfrac{1}{10}[/tex]

[tex]=5\times 10^{-1}[/tex]

Therefore, the value of the quotient is [tex]5\times 10^{-1}[/tex].

Step-by-step explanation:

5/6+1/15+1/12in on minute

Emma's best record is 59/60 kilometers per minute.

Given that, Emma personal record was 5/6 of a kilometer in one minute.

To add fractions there are three simple steps:

Step 1: Make sure the bottom numbers (the denominators) are the same. Step 2: Add the top numbers (the numerators), put that answer over the denominator.

Step 3: Simplify the fraction (if possible)

Given, after six months, she improved her record by 1/15 of a kilometer. After a year, she further improved her record by 1/12 of a kilometer.

Now, 5/6 + 1/15 + 1/12

LCM of denominators 6, 15 and 12 is 60.

50/60 + 4/60 + 5/60

= 59/60

Therefore, Emma's best record is 59/60 kilometers per minute.

=2.06cm

Therefore, the answer is 2.06cm

Answer:

A. -8

Step-by-step explanation:

Given the values of the function in a table, to determine the initial value of the function, you need to determine where x = 0.

Since the function is linear, the rate of change will be constant/the same.

To find the rate of change, you need to divide the change in the y value by the change in the x value.

X Y

+2↓ -5 | 7 ↓ -6

+2↓ -3 | 1 ↓ -6

+2↓ -1 | -5 ↓ -6

1 | -11

_____________

Since y changes by -6 and x changes by +2 every time, ∆Y/∆X = -6/+2 [Reduce] = -3/+1.

Slope = -3.

This means that y will decrease by 3 units every increase of 1 unit in x.

If (-1, -5) is a point which means that -1 is x when -5 is y.

We can apply the rate of change to see where x = 0.

So -5 + 1(-3/+1) → -5 + -3 = -8

Answer:

see explanation

Step-by-step explanation:

∠ 1 and ∠ 2 are adjacent angles and are supplementary, sum to 180° , so

5x + x + 54 = 180 ← equation to solve to find x

6x + 54 = 180 ( subtract 54 from both sides )

6x = 126 ( divide both sides by 6 )

x = 21

Then

∠ 1 = 5x = 5 × 21 = 105°

∠ 2 = x + 54 = 21 + 54 = 75°

Answer:

Step-by-step explanation:

Find the slope of each line. If the slopes are the same, the lines are parallel. Otherwise, the lines intersect.

Slope of line passing through (x₁, y₁) and (x₂, y₂) = (y₂-y₁)/(x₂-x₁)

Slope of line passing through (0, 5) and (-6, 3) = (3-5)/(-6-0) = ⅓

Slope of line passing through (-15, 0) and (-21, -2) = (-2-9)/(-21-(-2)) = 11/19

The lines intersect.
