Answer:

Step-by-step explanation:

Given the complex fraction;

[tex]-\frac{2}{x} +\frac{5}{y} / \frac{3}{y} - \frac{2}{x} \\[/tex]

First we will find the LCM of the numerator and the denominator as shown below;

[tex]\frac{-2y+5x}{xy} /\frac{3x-2y}{xy}[/tex]

Then we divide both equation by multiplying the numerator by the reciprocal of the denominator as shown;

[tex]= \frac{-2y+5x}{xy} * \frac{xy}{3x-2y} \\= \frac{-2y+5x}{3x-2y} \\[/tex]

This gives the required answer

Answer:

43.96 inches

Step-by-step explanation:

The formula for finding circumference is: 3.14*d(diameter). So if you plug in the 14 in the equation, you get 3.14*14 which is what I did to get the answer.

Hope this helped, mark brainliest and thanks! Have an awesome day! ;D

Answer:

266.9

Step-by-step explanation:

In order to find the circumference of a circle, you have to multiply the diameter by pi.

Circumference= 85 × 3.14

When multiplied this will get you 266.9

Answer:

Step-by-step explanation:

A) To determine the slant height, we would apply Pythagoras theorem to the right angle triangle formed. The opposite side would be the distance from the center of the pyramid to the center of any side. Therefore

Opposite side = 2/2 = 1 yrd

Slant height, L = hypotenuse

Adjacent side = 2 yrd

Hypotenuse² = opposite side² + adjacent side²

L² = 1² + 2² = 5

L = √5 = 2.24 yrds

Slant height = 2.24 yrds

B) Area of each triangular face = 1/2 × 2 × 2.24 = 2.24

Surface area of 4 triangular faces = 2.24 × 4 = 8.96 yrds²

Surface area of the remaining 5 faces of the cube = 5 × 2² = 20 yrds²

surface area of composite figure = 20 + 8.96 = 28.96 yrds²

C) volume = 1/3 × base area × height

Volume = 1/3 × 2² × 2 = 2.67 yrds³

Write the equations:

a +c = 15

a = 15-c

29.95a + 21.95c = 353.25

Replace a in the last equation:

29.95(15-c) + 21.95c = 353.25

Simplify:

449.25 - 29.95c + 21.95c = 353.25

449.25 - 8.00c = 353.25

Subtract 449.25 from both sides:

-8.00c = -96.00

Divide both sides by -8.00:

c = -96 / -8

c = 12

There were 12 children.

Answer:The length of the third side 2.5.

Step-by-step explanation:

We already know the length of two side but we don’t know the length of one side so we will represent it by b and we know they three lengths add up to 12b+5.

4b + 3b+15 +b =12b + 5

Solve for b.

8b +15=12b +5

-8b -8b

15+4b +5

-5 -5

4b/4=10/4

B=2.5

So the length of the third side is 2.5

4(2.5) + 3(2.5)+15+2.5=12(2.5)+5

35=35

The image of the front of the tower is missing, so i have attached it.

Answer:

Option B - 10,000 square millimeters

Step-by-step explanation:

From the image attached, we see that the dimensions of the front of the tower are;

Length; L = 200 mm

Width; w = 50 mm

Now, this front face takes the shape of a rectangle.

Area of rectangle = Length x width

Thus, plugging in the values of length and width, we will get;

Area of front face = 200 x 50

Area of front face = 10,000 square millimeters

Answer:

12,500 mm^2

Step-by-step explanation:

50 x 200 = 10,000 mm

(300 - 200 = 100) 100 x 50 x 1/2 = 2,500 mm

10,000 + 2,500 = 12,500 mm^2

Answer:

-22.1

Step-by-step explanation:

        =-14.1-8

        -22.1

Answer:

$40

Step-by-step explanation:

The earnings of Gabriel can be calculated with the formula:

P = Po * (1 + r/n)^(nt)

Where P = 900, r = 0.0325, n = 365 and t = 19

So we have:

P = 900 * (1 + 0.0325/365)^(365*19) = $1,668.81

The earnings of Daniel can be calculated with the formula:

P = Po * e^(rt)

Where Po = 900, r = 0.03375 and t = 19

So we have:

P = 900 * e^(0.03375*19) = $1,708.97

So the amount that Daniel will have more than Gabriel is:

1708.97 - 1668.81 = $40.16

Rounding to nearest dollar, the difference is $40

High School Mathematics 5+3 pts

Today, Sean left home at 8 a.m., drove to work, and worked from 9 a.m. until 5 p.m. On the drive back

home. Sean got stuck in slow-moving traffic for 2 hours, then stopped to have dinner, and finally got home

at 9:30 pm

The graph below shows Sean's distance, d from his home (in kilometers) as a function of the time, t (in

hours!

Complete the sentences below based on the graph of the function.

. Sean's workplace is located _____km from his home.

• Sean's speed when he was driving to work was ___ km/h.

. Sean's speed between 5 p.m. and 7 p.m. was _____km/h.

Answer:

Sean's workplace is located 20km from his home.

Sean's speed when he was driving to work was 20 km/h.

Sean's speed between 5pm and 7pm was 5 km/h.

Step-by-step explanation:

The formula for Speed = Distance in km ÷ Time in hours

a) Form the graph, we can see that Sean's workplace is located 20km from his home.

b) From the graph,

the distance from Sean's workplace from his home = 20km

We were told in the question that he drove from 8am - 9am.

This means Sean drove for 1 hour.

Since Speed = Distance in km ÷ Time in hours

Sean's speed = 20km ÷ 1 hour

= 20km/h

Therefore, Sean's speed when he was driving to work was 20 km/h.

c) From the graph, we can see that the distance Sean travelled was 10km from 5pm to 7pm

The time is from 5pm to 7pm, this means 2 hours

Speed = Distance in km ÷ Time in hours

Sean's Speed between 5pm to 7pm = 10km ÷ 2 hours

= 5km/hr

Therefore, Sean's speed between 5pm and 7pm was 5 km/h.

Answer:

57

Step-by-step explanation:

Firstly, we will need to calculate what x is.

To calculate this, the important property of the parallelogram to use is that adjacent angles are supplementary.

This means A and B are supplementary while B and C are also supplementary

what we are trying to say is that they add up to be 180

Thus,

5x + 18 + 3x -6 = 180

8x +12 = 180

8x = 180-12

8x = 168

x = 168/8

x = 21

Thus, the measure of angle B is 3x-6 = 3(21) -6 = 63-6 = 57

Now, another important property of parallelograms is that opposite angles are equal. This means that angle B= C = 57

Answer & Step-by-step explanation:

On a six-sided die, there are 4 numbers less than 5. So, we can write this as a fraction.

[tex]\frac{4}{6}[/tex] or we can write this fraction as [tex]\frac{2}{3}[/tex]

So, the probability of rolling a number less than 5 is [tex]\frac{2}{3}[/tex]
