t = 3 1/2

plz this question is worth 50 ponits

Answers

Answer:

t = 2 1/6

1/5 t + 2/5 = 5/6

Step-by-step explanation:

1/5 (t + 2) = 5/6

Multiply each side by 5

t+2 = 5*5/6

t+2 = 25/6

Subtract 2 from each side

t+2 -2 = 25/6 -12/6  ( using the same denominator)

t = 13/6 = 2 1/6

We can also distribute

1/5 t + 2/5 = 5/6

Subtract 2/5 from each side

1/5t = 5/6 -2/5

Get a common denominator

1/5t =25/30 - 12/30

1/5t = 13/30

Multiply each side by 5

t = 13/30 *5

t = 13/6

ANSWER : t = 2 1/6

1/5 t + 2/5 = 5/6

Step-by-step explanation:

1/5 (t + 2) = 5/6

Multiply each side by 5

t+2 = 5*5/6

t+2 = 25/6

Subtract 2 from each side

t+2 -2 = 25/6 -12/6

t = 13/6 = 2 1/6

We can distribute

1/5 t + 2/5 = 5/6

Subtract 2/5 from each side

1/5t = 5/6 -2/5

Get common denominator

1/5t =25/30 - 12/30

1/5t = 13/30

Multiply each side by 5

t = 13/30 *5

t = 13/6

Answer:

212.5 cm² and 120 in²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

(4)

Here b = 25 and h = 17, thus

A = 0.5 × 25 × 17 = 212.5 cm²

(5)

Here b = 12 and h = 20, thus

A = 0.5 × 12 × 20 = 6 × 20 = 120 in²

5. The longest leg of a right triangle is 8 meters and another side is 6 meters. Calculate the
perimeter. 5

Answers

Answer:

24 meters

Step-by-step explanation:

Alright. Your question had errors, but I managed to scramble together some answers.

The right triangle has a total of 3 sides, 2 which are 8 and 6. We need to find the hypotenuse.

Let's use the Pythagorean Theorum.

a^2 + b^2 = c^2

8^2 + 6^2 = c^2

64 + 36 = 100

To get c by itself, square root it.

[tex]\sqrt{100} =10[/tex]

You found the hypotenuse :D

Add it up!

8 + 6 + 10 = 24 meters

Answer:

Remember this formula.

Step-by-step explanation:

[tex]\sqrt{a^{2}+b^{2}=c^{2}[/tex]

If your legs are 8 and 6, the last side is the hypotenuse, which is always the largest side of a right triangle. You calculate it's length by taking the measurements of leg A and leg B, and squaring both of them, or raising them both by the power of 2.

This will equal C, or your hypotenuse, but it will be squared, so you have to find its square root to get the actual measurement, which is why the equation has a square root sign over it, so the answer is automatically squared when put into a calculator.

8 x 8 = 64 [or [tex]8^{2}[/tex]]

6 x 6 = 36 [or [tex]6^{2}[/tex]]

[tex]8^{2}+6^{2}=100\\\sqrt{100}=10[/tex]

[tex]\sqrt{8^{2}+6^{2}=10[/tex]

The total earnings for hour 3 are $______.


The missing part of the picture is:
4x + 2y = 84
3x + 5y = 126

Answers

Answer:

see below

Step-by-step explanation:

In the system of equations, x represents the,  price to wash a car and y represents the price to wash an SUV.

If the system of equations is graphed in a coordinate plane, the coordinates (x, y) of the intersection of the two lines are the price of the car wash (x) and the price of the SUV wash (y)______.

x=12 and y = 18

x+y = 12+18 = 30

The total cost of 1 car and 1 SUV is $_30____.

5x+4y = 5(12)+4(18) = 60+ 72 =132

The total earnings for hour 3 are $_132_____.

Answer:

x: cost of 1 car wash

y: cost of each SUV wash

(12,18)

The total cost of 1 car and 1 SUV is $30

The total earnings for hour 3 are $132

Step-by-step explanation:

4x + 2y = 84

y = 42 - 2x

3x + 5y = 126

3x + 210 - 10x = 126

7x = 84

x = 12

y = 42 - 2(12) = 18

1 car and 1 SUV

12 + 18 = 30

Find the area of the regular polygon, round to nearest hundredth. a 93.23 b 186.45 c 933.25 d 466.13

Answers

Answer:

See Explanation and Attachment

Step-by-step explanation:

Your question is incomplete as the diagram of the polygon is not attached.

However, I'll give a general guide to calculate the area of a regular polygon.

If you apply these steps, you'll be able to solve your question.

The area of a regular polygon is calculated this.

Area = ½ap

Where a represents the apothem of the polygon and p represents the perimeter of the polygon.

The term "apothem" means the distance between the centre of the polygon and the base of the polygon.

Take for instance, the attachment below.

The polygon is a regular hexagon (it has 6 sides)

The apothem, a = 8.2 ft

The perimeter, p = The sum of all sides of the hexagon

p = (7.6 + 7.6 + 7.6 + 7.6 + 7.6 + 7.6)ft

p = 45.6 ft

Hence, the area of the polygon

A = ½ap becomes

A = ½ * 8.2 * 45.6

A = ½ * 373.92

A = 186.96ft²

Step-by-step explanation: yes

The required volume of the composite figure of the sphere on the top of the cone is 312π mm³. Option c is correct


The sphere is stacked on top of a cone. They both share a circular base. The radius of the circle is 6 millimeters. The height of the cone is 14 millimeters. The volume of the composite figure is to determine.


What is volume?

Volume is defined as the ratio of the mass of an object to its density.

Volume of composite figure =  Volume of semi-sphere  + Volume of cone
                                              =   2/3πr³ + 1/3πr²h
                                              =  2/3*6³π + 1/3*6²*14π
                                              =   312π mm³

Thus, the required volume of the composite figure of the sphere on the top of the cone is 312π mm³.

Find the constant of proportionality (r) in the equation: y = rx

r = ?

Thanks :)

Answers

Answer:

r = 11

Step-by-step explanation:

Given

The above table

y = rx

Required.

Find the constant of proportionality.

To find the constant of proportionality, we simply test the values of y and x in the given formula.

Using y = rx

Make r the subject of formula by dividing both sides by x

y/x = rx/x

y/x = r

r = y/x

From the above table of data;

When x = 2, y = 22

So, r = 22/2

r = 11

When x = 7, y = 77

So, r = 77/7

r = 11

When x = 9, y = 99

So, r = 99/9

r = 11

Notice that r maintains the value of 11 all through.

Hence, the constant of proportionality, r for the above data is 11

Answer:

r = 11
