Answer:

Option (4)

Step-by-step explanation:

From the picture attached,

Side lengths of the triangles have been given in the picture attached.

If these triangles are similar, their corresponding sides will be proportional.

By this property of similarity,

[tex]\frac{19.5}{5}= \frac{20}{8}[/tex]

3.9 = 2.5

Which is not true.

Therefore, these triangles are not similar.

Option (4) will be the answer.

so it looks like it's $245 or it's $85

Step-by-step explanation:

because your equation is 5n+45

Alternatively:

if she gets 5 dollars for every 10 sold then after selling 40 it would be

40/5=8 then it becomes 8*5+45=85

If rectangular field has an area of 646 square feet. The width of the field is 19 feet. Then length of the field is 71.77 feet.

The area of Rectangle is length times of width.

Given,

Area of rectangular field is  646 square feet.

width of the field is 19 feet.

We need to find the length of the field.

Area of rectangle=Length×Width

646=Length×19

Divide both sides by 19

Length=646/9

Length=71.77 feet

Hence 71.77 feet is the length of the field.

Answer:

30%

Step-by-step explanation:

Selma spent 3/10 of her allowance on a new backpack.

Hence, the percent of her allowance that she spent is calculated as:

Fraction of allowance spent on Backpack × 100

= 3/10 × 100

= 0.3/1 × 100

= 30%

Therefore, Selma spent 30% of her allowance on a new backpack.

Step-by-step explanation:

use the following equation

aₙ=a₁+(n-1)d

Where d is the common difference

n is the term

a₁ is the first term

the common difference is -3 (149-152)

this means we have

152+(30-1)*-3

Compute this and get

Answer:

B) 4

Step-by-step explanation:

Use the slope formula:

slope [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Let:

[tex](x_1 , y_1) = (1 , -2)\\(x_2 , y_2) = (2 , 2)\\[/tex]

Plug in the corresponding numbers to the corresponding variables:

slope:

[tex]m = \frac{2 - (-2)}{2 - 1} \\m = \frac{2 + 2}{2 - 1}\\m = \frac{4}{1} = 4[/tex]

I think the answer is 3.8.

Step-by-step explanation:

Because there is 0.6 for the blue paint and 0.4 for the white paint, and p=red paint. If you divide all 3 of them equally into 2 jars, you have add 0.4 and 0.6 together and then divide by 2, then substract it from 2.4. You will get 1.9, then multiply 1.9 by 2, that is how much Henri and Talia used for the red paint, which is 3.8 liters.

62.5% of the parking spaces are taken.

Step-by-step explanation:

Given

To determine

What percent of the parking  spaces are taken?

The percentage of taken spaces of the part can be determined using the formula

% of Taken spaces = [Taken spaces / Total Spaces ] × 100

                               = [1875 / 3000] × 100

                               = 0.625 × 100

                               = 62.5%

Therefore, 62.5% of the parking spaces are taken.

Answer: 18.05556

Step-by-step explanation: 65 Kilometer/Hour (km/h) =. 18.05556 Meter/Second (m/s) Kilometer/Hour : Kilometers per hour (also spelling: kilometer per hour) is a unit of speed, defined as the number of kilometers travelled in one hour. The symbol of kilometer per hour is km/h or km•h−1.

Hopefully this helps :D

The units for distance and time are 3250/3 m/min and 325/18 m/s

A unit rate means a rate for one of something. We write this as a ratio with a denominator of one.

For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.

Given that, we need to create two equivalent rates to 65 km/h with units for distance and time that are not kilometers and hours.

So,

65 km/h = 65 x 1000 m / 60 min = 3250/3 m/min

65 km/h = 65 x 1000 m / 3600 sec = 325/18 m/s

Hence, the units for distance and time are 3250/3 m/min and 325/18 m/s

Answer:

QR = 4x - 6

Step-by-step explanation:

A triangle is a polygon that has three sides and three angles. There are different types of triangles such as equilateral triangle, isosceles triangle, scalene triangle, right angled triangle.

The perimeter of a triangle is a measure of the length of the sides. It is the sum of all the length of the three sides of the triangle.

From the question:

Perimeter of triangle PQR = PQ + PR + QR

But PR = 3x - 1, PQ = x + 1, Perimeter of PQR = 8x - 6.

Therefore substituting gives:

8x - 6 = (x + 1) + (3x - 1) + QR

8x - 6 = (x + 3x + 1 - 1) + QR

8x - 6 = 4x + QR

QR = (8x - 6) - 4x

QR = 4x - 6
