Answer:

2 days

Step-by-step explanation:

According to the problem, calculations of given data are as follows,

Rental charges per day = $68.64

Rental per mile = $0.12

Total miles = 500

Total spend = $210

Let number of days = X

So, we can find number of days by using following equation,

($68.64 × X ) + ( $0.12 × 500) = $210

$68.64 X + $60 = $210

$68.64 X = $210 - $60

$68.64 X = $150

X = $150 ÷ $68.64

X = 2.18 or 2 Days

Answer:

100 boards

Step-by-step explanation:

Step one:

Given data

We are told that Cynthia was paid 20 cents per board for painting the fence

that is for 1 board painted she gets $0.2

If she was paid $10

let us find the number of boards she painted for $10

= 10/0.2

=50 boards

This means that the total boards were 50*2= 100 boards

Answer:

1/2

Step-by-step explanation:

It will be either heads of tails equally likely.

It’s still 1/2. Flipping a coin is an independent event. In other words, the outcome of the next flip is uninfluenced by what has happened previously. It’s as if it were the first time you ever flipped the coin. The probability is unaltered.

Answer:

x > 3 or x < -1

Step-by-step explanation:

4x - 10 > 22

4x > 12

divide both sides by 4

x > 3

x - 5 < -6

   +5    +5

x < -1

Answer:

71.092

Step-by-step explanation:

The number in the standard form i.e. seventy-one and ninety-two thousandths should be considered as the 71.092.

Since the numbers are mentioned in alphabets like

seventy-one and ninety-two thousandths

We have to write in standard form

So, it should be like 71.092.

Hence, The number in the standard form i.e. seventy-one and ninety-two thousandths should be considered as the 71.092.

Step-by-step explanation:

Answer: The perimeter of the largest triangle = 117 units.

Step-by-step explanation:

Sides of smaller triangle = 10,20 and 15 units

Longest side = 20 units

Longest side of larger triangle = 52 units

Sides of two similar triangles are proportional.

Let k be proportionality constant.

[tex]k=\dfrac{\text{Length in larger triangle}}{\text{Length in smaller triangle}}[/tex]

[tex]k=\dfrac{52}{20}\\\\\Rightarrow\ k=\dfrac{13}{5}[/tex]

Length of other two sides,

[tex]10\times\dfrac{13}{5}, 15\times\dfrac{13}{5}\ i.e.\ 26\text{ units}, 39\text{ units.}[/tex]

So sides of larger triangle = 52 units, 26 units , 39 units

Perimeter of largest triangle = 52 +26+39 = 117 units

Hence, the perimeter of the largest triangle = 117 units.

Step-by-step explanation:

Hi there!

Question 4 - the answer will be 5. Since the scale factor is 5, we would (hypothetically) multiply the area by 5 to get the new area of XYZ, so area XYZ is 5 times the area of ABC.

Question 5 - A.

First we multiply 45 by 12 to find the amount in inches. This is 540. Now, we divide that by 6 to get 90. This is our scale factor in inches, but the answers only show the scale in feet, so we have to convert. Divide 90 by 12 to get 7.5.

Answer:

An equation of a line with slope -3/2 and x-intercept (4,0) will be:

[tex]y\:=\:-\frac{3}{2}x\:+\:6[/tex]

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

Given

now substitute m = -3/2 and the point (4, 0) in the slope-intercept form of line equation

[tex]y = mx+b[/tex]

[tex]0\:=\:-\frac{3}{2}\left(4\right)\:+\:b\:\:\:\:\:[/tex]

[tex]-6+b=0[/tex]

Add 6 to both sides

[tex]-6+b+6=0+6[/tex]

Simplify

[tex]b=6[/tex]

Thus, the y-intercept b = 6

now substitute m = -3/2 and b = 6  in the slope-intercept form of line equation

[tex]y = mx+b[/tex]

[tex]y\:=\:-\frac{3}{2}x\:+\:6[/tex]

Therefore, an equation of a line with slope -3/2 and x-intercept (4,0) will be:

The correct classification of the triangle should be considered as the right triangle.

A right triangle or right-angled triangle, or more formally an orthogonal triangle, formerly called a rectangled triangle, is a triangle in which one angle is a right angle, i.e., in which two sides are perpendicular. The relation between the sides and other angles of the right triangle is the basis for trigonometry.

here, we have,

given that,

In the case when the sum the two given angles is 90,

so, the other angle will be 90

so, its a right triangle.

A right angled triangle is a triangle in which one of the angles is 90°. A 90-degree angle is called a right angle, and hence the triangle with a right angle is called a right triangle. Further, based on the other angle values, the right triangles are classified as isosceles right triangles and scalene right triangles.

Hence, The correct classification of the triangle should be considered as the right triangle.

Answer:

total surface area = 76 sq.cm

Step-by-step explanation:

total surface area of cuboid = 2 ( lb + lh + bh )

( where l is length , b is width and h is height )

so, surface area :

= 2[ (5×4) + (5×2) + (2×4) ]

= 2 [ 20 + 10 + 8 ]

= 2 × 38

Jacob is [tex]16[/tex] years old.

Step-by-step explanation:

Let the age of Jacob be [tex]x[/tex] years.

Jacob’s sister is [tex]5[/tex] years younger than he is.

So, the age of Jacob's sister be [tex]x-5[/tex] years.

Jacob's twin brothers are [tex]3[/tex] years older than he is.

So, the age of each of the twin brother be [tex]x+3[/tex] years.

Jacob's mom is [tex]3[/tex] times his age.

So, the age of Jacob's mom be [tex]3x[/tex] years.

Jacob's dad is [tex]4[/tex] years older than his mom.

So, the age of Jacob's dad be [tex]3x+4[/tex] years.

Now, the total of all the ages of all his family members is [tex]165[/tex] years.

So, [tex]x+x-5+x+3+x+3+3x+3x+4=165[/tex]

[tex]\Rightarrow 10x+5=165[/tex]

[tex]\Rightarrow 10x=165-5[/tex]

[tex]\Rightarrow 10x=160[/tex]

Answer:

We conclude that the expression of the price p of a coat reduced by a 5% discount​ will be: 0.95 p      

Step-by-step explanation:

Let 'p' be the original price

Discount = 5% = 0.05

The discount amount can be calculated by multiplying the original price by 5% or 0.05

Discount Amount = 5% × p

                             = 0.05 × p

                             = 0.05 p

Given that the price p of a coat reduced by a 5% discount​.

Thus, the price after 5% discount​ can be calculated by subtracting the discount amount i.e. 0.05 p from the original price p.

Thus,

The expression of the price p after 5% discount​ = p - 0.05 p

                                                                                = 0.95 p

Therefore, we conclude that the expression of the price p of a coat reduced by a 5% discount​ will be: 0.95 p                                                

Answer:

a. AB = 17 m

b. AC = 19.2

Step-by-step explanation:

✔️Length of AB:

Apply pythagorean theorem

AB² = (25 - 10)² + 8² = 15² + 8²

AB² = 289

AB = √289

AB = 17 m

✔️Length of AC:

Apply pythagorean theorem

AC² = AB² + BC²

AC² = 17² + 9²

AC² = 370

AC = √370

AC = 19.2 (to 1 d.p)
