Hannah completed 40 problems in 32 minutes.
Put in a unit ratio

Answers

Answer 1

Answer: 1.25 problems/min and in ratio it is 1.25/1

We can keep the rate as problems/min

So, in 32 mins Hannah can complete 40 problems.

32 mins --> 40 problem

1 min --> 40/32

          --> 1.25

So, 1.25 problems can be created per minute.

D) y= 3.72

Answers

Answer:

Below.

Step-by-step explanation:

Using Pythagoras theorem, let's find y.

=> y² = 3² + 3²

=> y² = 9 + 9

=> y² = 18

=> y = √18

=> y = 4.24 (Estimated)

Given the set of domain D = {-3, -2, -1, 0, 1, 2, 3}

Construct /Do the following:
1. Set of ordered pairs such that the range is one less than the domain.
2. Construct table of values such that the range is 2 more than the domain.
3. Write the equation for numbers 1 and 2.
4. Graph numbers 1 and 2 on separate coordinate plane.​​

Answers

Set of ordered pairs such that the range is one less than the domain is {-4, -3, -2, -1, 0, 1, 2}The equation 1 will be y = x - 1The equation 2 will be y = x + 2

Given the domain of values D = {-3, -2, -1, 0, 1, 2, 3}

1) If the set of range is one less than the domain, the required range will be:

Range = {-4, -3, -2, -1, 0, 1, 2}

2) If the set of range is 2 more than the domain, the required range will be:

Range = {-1, 0, 1, 2, 3, 4, 5}

The table of values is given as:

x       y

-3  |  -1

-2  |   0

-1  |   1

0   |   2

1    |   3

2   |   4

3   |   5

2) For equation 1, we will use the coordinate points (0. -1) and (1, 0)

The equation in slope-intercept form is given as y = mx + b

m = 0-(-1)/1-0

m = 1/1 = 1

Since the y-intercept is at (0, -1), hence b = -1

Substitute the given value into the formula:

Recall that y = mx + b

y = 1x + (-1)

y = x - 1

Hence the equation 1 will be y = x - 1

For equation 2, we will use the coordinate points (-1, 1) and (0, 2)

The equation in slope-intercept form is given as y = mx + b

m = 2-1/0-(-1)

m = 1/1 = 1

Since the y-intercept is at (0, 2), hence b = 2

Substitute the given value into the formula:

Recall that y = mx + b

y = 1x + 2

y = x + 2

Hence the equation 2 will be y = x + 2

4) The graph of each equation on a different coordinate plane is attached.

wahts the gcf and lcm of 18 and 30

Answers

Hey there. So first, to work out the LCM, we need to find the multiples of 18 and 30. We’ll start with 18, and we’ll stop at a reasonable number.

18, 36, 54, 72, 90.
30, 60, 90, 120.

Already we notice that 90 is the smallest multiple that is evident in both numbers. So 90 is your LCM.

Now for the GCF, we want to begin by creating a factor tree for 18 and 30. I found one on the internet so it’s easier to view.

When finding the GCF, you want to circle all the prime numbers you have, so in this case, for 18, we have 2 x 3 x 3. They’re all prime.

For 30, we have 2 x 3 x 5. They’re all prime.

If we now circle the numbers that are common in both so we have (2) in 18 and 30, and we have (3) in 18 and 30. We are left with 5 and 3, ignore them for now. Because we managed to circle 2 and 3, if we multiply them together, we get 6. So the GCF of 18 and 30 is 6. And the LCM of 18 and 30 is 90.

Sorry if this sounds confusing, i tried my best.

HELP! Jessica edits the school yearbook. She says the the dimensions of the student photo are proportional to the dimensions of the small photo, medium photo, and large photo found throughout the yearbook. Is she correct? Explain your reasoning.

Answers

Answer:

no

Step-by-step explanation:

The ratio of width to height for the different photos are ...

 student: 1 : 3/2 = (2/2):(3/2) = 2 : 3

 small: 2 : 5/2 = (4/2):(5/2) = 4 : 5

 medium: 4 : 5 . . . (same as small)

 large: 8 : 10 = 4 : 5 . . . (same as small and medium)

The small, medium, and large photos all have proportional dimensions, but those are not proportional to the dimensions of the student photo.

Solve for x.
2x−4=6−3x

A: x= -0.4
B: x= 2
C: x= -2
D: x= 0.4

Answers

Answer:

x = 2

Step-by-step explanation:

First, let's write out our equation:

[tex]2x-4=6-3x[/tex]

I want to isolate x on one side, so first, I'll add 4 to both sides to remove the -4 from next to 2x:

[tex]2x-4+4=6-3x+4\\2x=-3x + 10[/tex]

Notice that I combined like terms with the -4 and 4 (to get 0) and the 6 and 4 on the right side (to get 10). Next, I'll add 3x to both sides:

[tex]2x + 3x = -3x + 3x + 10[/tex]

And then I'll add like terms:

[tex]5x=10[/tex]

Now, all we have to do is divide both sides by 5:

[tex]5x/5=10/5\\x=2[/tex]

And there's our answer. Hopefully that's helpful! :)

The cost of paving a square room at the rate of RS.15 per m2 is Rs.1500. What is the Area and the Perimeter of the room?​

Answers

hope it helps you...................

....

..

The area of the room is equal to 100 m² and perimeter is 40m

What is Area?

The area is the space covered by the object. It is the region occupied by any shape. While measuring the area of a square, we consider only the length of its side. All sides of a square are equal; hence, its area is equal to the square of the side and the perimeter of a square = 4 ×  side units.

Given here: Unit rate of painting per meter square=15 and it cost 1500 in total

Thus Area = 1500/15

                  =100 m²

Then a²=100 and a=10

∴Perimeter of the square room is = 4×10

                                                        =40 m

Hence, The area of the room is equal to 100 m² and perimeter is 40m

Annie, Brianna & Carly are selling fruit boxes to raise money for their soccer team. All together the girls have sold 105 boxes of fruit. Carly has sold ten more than three times Brianna's sales. Brianna sold five more than Annie. How many boxes of fruit did Carly sell?

Answers

Step-by-step explanation:

Annie = x

Brianna = y

Carly = z

Now,

x + y + z = 105 ...(1)

Carly has sold ten more than three times Brianna's sales.

z = 10 + 3y ...(2)

Brianna sold five more than Annie.

y = 5 + x ...(3)

Now,

z = 10 + 3y

z = 10 + 3(5 + x)

z = 10 + 15 + 3x

z = 25 + 3x

Now,

x + y + z = 105

x + (5 + x) + 25 + 3x = 105

5x + 30 = 105

5x = 105 - 30

5x = 75

5x/5 = 75/5

x = 15

So,

y = 5 + x

y = 5 + 15

y = 20

Now,

z = 25 + 3x

z = 25 + 3(15)

z = 25 + 45

z = 70

Thus,

Annie Sold 15 boxes

Brianna Sold 20 boxes

Carly Sold 70 boxes

100% - 80% = 20%

To find the original price, you can multiply by 120%
