If y is directly proportional to Vx, and y = 25 when x = 3, find x when
y = 100

Answers

Answer 1

9514 1404 393

Answer:

  x = 48

Step-by-step explanation:

It looks like your proportion is ...

  y = k√x

Then k can be found as ...

  k = y/√x = 25/√3

__

For y = 100, the value of x can be found from ...

  100 = (25/√3)√x

  4√3 = √x . . . . . . . . . . multiply by √3/25

  48 = x . . . . . . . . . . . . . square both sides

If Y Is Directly Proportional To Vx, And Y = 25 When X = 3, Find X Wheny = 100

Ingrid has $28 to buy oil paints for her painting class. Each tube of paint costs $8. How many tubes can she buy? Do not include units in your answer.​

Answers

Answer:

3

Step-by-step explanation:

You have to divide 28 divided by 8.

28/8 = 3.5

I'm pretty sure you can't buy half a tube of paint, so Ingrid would only be able to buy 3.

Brazil's currency is called the real and is denoted with this symbol: R$. A plumbing contractor allotted R$10,236 in his bank account to complete three residential jobs. If he estimates Job 1 to cost R$2,477, Job 2 to cost R$2,263 and Job 3 to cost R$3,218, how much money will he have left in the account for unexpected costs?

Answers

Step-by-step explanation:

I added together his estimations and then subtracted the total from how much money was in his bank.

2,477+2,263+3,218=7,958

10,236-7,958=2,278

Find an equation for the perpendicular bisector of the line segment who’s endpoints points are (-9,3) and (1,7).

Answers

Answer:

y = 2/5x + 33/5

Step-by-step explanation:

(-9,3) and (1,7)

m=(y2-y1)/(x2-x1)

m=(7-3)/(1+9)

m=4/10

m = 2/5

y - y1 = m(x - x1)

y - 3 = 2/5(x + 9)

y - 3 = 2/5x + 18/5

y = 2/5x + 33/5

Answer:

missing angle = 41, b. 45, c. 72

Step-by-step explanation:

A circle has 360 degrees, so add all of the existing angles

48+45+129+97 = 319 and 360-319 = 41

25/200 = 12.5% so 12.5% of 360 = .125x360 = 45

Sector 129 represents 129/360 = 35.83% so 200x.3583=72 cars

Does the given side lengths make a right triangle? 9, 37, 40

Answers

Basically can you do pythagoras on it
40 would have to be the hypotenuse as it’s the largest, so if 9^2 + 37^2 = 40^2 then we have a right triangle
9^2 + 37^2 = 1450
40^2 = 1600
1450 doesn’t equal 1600, so those side lengths don’t make a right triangle

The ratio of yellow flowers to the total number of flowers in a bucket is 5 to 9. How many flowers are yellow if there are 45 lowers in all

Answers

Hey y’all are you doing this morning I just got home from school and I’m just going to sleep in the morning I woke you to the sleep I love y’all I woke you to the sleep bye love y’all I woke

Answer:

There are 25 yellow flowers.

Step-by-step explanation:

The ratio is yellow/all and 5/9.

We know that all the flowers in total equal 45, which is a multiple of 9.

So 45 divided by 9 = 5.

So all I had to do was multiply 5/9 times 5/5.

So then we get the ratio of 45 total flowers with 25 yellow flowers.

How many solutions does this problem have
Y=-2x -4
Y= 3x plus 3

Answers

Answer:

There is one possible solution

Step-by-step explanation:

Here, we want to get the number of solutions

We can proceed to solve the equation

we have two y values so we can directly equate the x parts

-2x - 4 = 3x + 3

3x + 2x = -3-4

5x = -7

x = -7/5

To get y, we substitute

We can only get one value of y too

So we have a point (x,y) as the solution to the system of equations

Madison represented the sentence “The product of 3 and the difference of Negative 4 and the quotient of a number and Negative 2 is at most 5” by using the inequality 3 (Negative 4 minus StartFraction n over negative 2 EndFraction) less-than 5.
Which best describes Madison’s error?
“The difference of –4 and the quotient of a number and –2” should be written as StartFraction negative 4 minus n over negative 2 EndFraction.
“The product of 3 and the difference of –4 and the quotient of a number and –2” should be written as 3 (negative 4) minus (StartFraction n over negative 2 EndFraction).

Joe measures side lengths of triangular canvas to be 22 inches, 10 inches and 11 inches. Could those be correct measurements?

Answers

Answer:

Incorrect measurement

Step-by-step explanation:

Given

Shape: Triangle

Length: 22in, 10in and 11in

Required: Determine if the measurements are correct

For the measurement of a triangle to be true, the sum of any 2 sides must be greater than the length of the third side.

i.e.

[tex]22 + 10 > 11[/tex] --- True

[tex]22 + 11 > 10[/tex] --- True

[tex]11 + 10 > 22[/tex] --- False

Since all three conditions are not true, then the measurements are incorrect
