If Mark takes 7 hours to paint a house and Hanna takes 5 hours to paint the same house, how much time will it take both of them to paint the house? Please explain!

Answers

Answer 1

Answer:

2 hours and 42 minutes

Step-by-step explanation:

we can see that both people are painting the same house, however 1 person goes faster than the other one

lets start by putting our numbers into fractions then finding a like value. 35 in this case. 1/7 equals 5/35 and 1/5 equals 7/35 now we add these together and get 13/35. our next step is to flip this to 35/13 and take put any whole numbers. in this case 2 whole numbers can be made

leaving

9/13

(0.69)

converting this to minutes is 42 minutes.

Let f(x) = –7x + 9. Suppose you add 2 to the input of f to create a new function g, then multiply the output of function g by –3 to create function h. What are the slope and y-intercept of the graph of function h?


slope = ?
y-intercept = ?

Answers

Answer:

Im pretty sure slope is 21 and y intercept is 15

The slope is 21 and the y-intercept is -33 of the graph of function h.

What is a Linear Function?

A linear function is defined as a function in the form of f(x) = mx + c where 'm' and 'c' are real numbers.

It represents the line's slope-intercept form, which is written as y = mx+ c.

The function is given in the question below as

f(x) = –7x + 9

⇒ f(x) = –7x + 9

Add 2 to the input of f to create a new function g,

⇒ g(x) = –7x + 9 + 2

⇒ g(x) = –7x + 11

Now, multiply the output of function g by –3 to create function h.

⇒ h(x) = (–7x + 11) × -3

⇒ h(x) = 21x - 33

Compare to the line's slope-intercept form,

Therefore, slope = 21 and y-intercept = -33

I can’t upload any working right now so I hope you’ll understand from an explanation, all it is is a hidden polynomial. You can say:

Let y=x^2
Then the equation becomes:
y^2 - 18y + 81
Factorise that to give you:
(y-9)(y-9) Or (y-9)^2
But remember, y=x^2. So the equation becomes:
(X^2-9)(X^2-9)

Suppose Adriana spends $ 73.00 dollars on T-shirts and pants. A T-shirt costs $5.50 and pants cost $25.50. How can you represent this situation with an equation?

Answers

Answer:

73.00=5.50x+25.50y

Step-by-step explanation:

Answer:

25.50x + 5.50y = 73.00

Step-by-step explanation:

Pick a variable for x and y (x is pants and y is T-shirt)

Since she buys pants and T-shirts you add the two values

Since she spent $73 you make it equal to 73

angles on the same side of a transversal and in between the lines it intersects are _____?

Answers

It means it a supplementary angle (adds to 180)

Can you help me find the values of x and z?

Answers

Answer:

x = 96

z = 25

Step-by-step explanation:

x and 84 are supplementary angles.

this means that they add together to make 180.

using this, you can make the following equation:

x + 84 = 180

subtract 84 from both sides of the equation

x + 84 - 84 = 180 - 84

x = 180 - 84

x = 96

84 and 3z + 9 are vertical angles

vertical angles are equal.

using this, you can make the following equation:

84 = 3z + 9

subtract 9 from both sides of the equation

84 - 9 = 3z

75 = 3z

divide both sides of the equation by 3

75/3 = 3z/3

25 = z

Answers

1 width is 64 cm
2 option 2
3 28.5
4 175
5 224

1. A kite has a width to length ratio of 4:5, so let the width be 4x and the length be 5x. We know that the length is 80 cm. 80 = 5x

Divide by 5.

16 = x.

Now, the width is 4x.

16 times 4 is 64.

The width is 64.

2. Find the unit rate for each juice. The unit rate is ml / dollar.

The first juice has a unit rate of 150 / 1.

The second has a unit rate of 500 / 1.75.

The third has a rate of 1000 / 4.

The fourth has a rate of 2000 / 7.25

Put all values into a calculator. (First: 150, Second: 285.714285, Third: 250, Fourth: 275.862068966)

Whichever one can buy the most ml for a dollar is the best buy.

In here, that is the SECOND rate, which is 1.75 for 500 ml.

She earns 3% commission on all her sales, so if s represents her sales, she'd earn .03s. Inhere, she sells $950 in total. That is her total sales.

So you plug $950 into the equation as s.

.03 (950) = 28.5

She earned $28.50.

Poor Maya!

3. You set it up in ratios. She needs 250 mL of milk for every 325 mL of pancake mix. 250 milk / 325 mix.

But she only has 225 mix.

So you set up 250 milk / 325 mix = M milk / 225 mix

As in all proportions, you cross multiply.

250 x 225 = 325 x M

56250 = 325M

Divide by 325 on both sides.

173.076923077 = M

She needs about 175 mL. The fourth choice.

4. There are a total of 1120 spectators, made of only home team fans and visiting team fans.

There is a total of 100% of people, and 80% are supporters of the home team, so to find the supporters of the visiting team you subtract 100% by 80%.

100 - 80 = 20.

So 20% of the spectators are supporters of visiting team. Now 20% of the total, and 20% = .20.

.20 x 1120 = 224

224 people are fans of the visiting team.

5. A 500-mL bottle of insect repellent has 22 mg of DEET, a chemical used to keep mosquitos away. The same insect repellent sells in 710-mL bottles. Which of the following proportions can be used to find the amount of DEET in the larger bottle? *

If a 500 mL bottle has 22mg of DEET, then 500ml / 22mg

So set up the equation 500 / 22 = 710 / x

Now, cross multiply.

500x = 710 times 22.

500x = 15620

Divide by 500.

x = 31.24

Other possible proportions are:

22 / x = 500 / 710

x / 22 = 710 / 500

22 / 500 = x / 710

The ratio is 2in to 8mm
so safe to assume 1in represents 4mm.
1in = 4mm

The equation to find the length is:
1.5in = x mm
if we know that 1in is 4mm, 0.5in is 2 mm. So the answer is:
1.5in = 6mm.

The equation to find the width is:
0.75in = x mm
0.75 is 3/4, and 1in = 4mm, so 3/4 of 4 is 3. Therefore,
0.75in = 3 mm

Finally, the answer is:
Length = 6mm
Width = 3mm

I have written an automated script to run tests on your code, and it depends on the POST variables being labeled correctly within the HTML Form. 1) "pet_name" 2) "pet_id" 3) "pet_weight" 4) "birth_date" The following rules must be enforced by your PHP script about the input. No field is allowed to be blank. Maximum length of pet name is 20 characters. Pet ID must be 4 lowercase letters followed by 3 numbers. Example: abcd123 Max length of pet weight is 7 characters.
