What is an equation of the line that passes through the point ( − 1 , − 3 ) and is perpendicular to the line x − 2 y = 14?

Answers

Answer:

y = -2 -5

Step-by-step explanation:

x - 2y = 14

-2y = -x + 14

y = 1/2x - 7

-3 = -2 (-1) + b

-3 = 2 + b

-5 = b

y = -2 -5

one angle of a triangle measures 35°. A second angle measures (3x)°, and the third angle measures 2x - 20)°. what is the value of x?

Answers

Answer:

x = 33

Step-by-step explanation:

Sum of the angles in a triangle is 180 so,

35 + 3x + 2x - 20 = 180

35 + 5x - 20 = 180

15 + 5x = 180

5x = 180 - 15

x = 165/5

x = 33

Pls help with finding slope and y intercept from 2 points‼️‼️❗️❗️❗️❗️

Answers

step 1: plot your points.

step 2: find the rise over run

step 3: place the rise over run in decimal form. say its 5 to the side and 2 up 2/5 (if it was a negative rise such as 2 down it would be -2/5)

step 4= find where it crosses the y line such ex: 0,8 it would be 8 (if it were negative it would be 0,-8: -8)

then put in y intercept form: y=2/5x+8

this is wrong bc i need a problem not only one number what is the problem for "When I triple my number and add four, I get ten. What is my number?" this

Answers

Answer: 2

Step-by-step explanation:

Let's substitute the number as x in the equation.

Triple means you multiply it by 3.

Then you add four, and get 10.

We can write that like this:

3x + 4 = 10

Then subtract 4 from both sides:

3x = 6

And then divide both sides by 3:

x = 2

So the number is 2.

The difference between four times a number x and 5 is 24.

Answers

Answer:

4x - 5 = 24

x= 7.25

Step-by-step explanation:

4x - 5 = 24

4x= 24 + 5

x = 29 / 4 = 7.25

Answer:

Step-by-step explanation:

Prime factorization requires dividing by primes starting with smallest prime number

402/2=201

201/3=67, 67 is prime so we cannot go further so the prime factorization of 402 is

2X3X67

If the perimeter of a rectangle garden with a width of 15 is 125, what is the perimeter of the daily record it if the scale factor is 60%

Answers

Answer:

(here i assume that the daily record is another rectangle)

For a rectangle with width W and length L, the perimeter is:

P = 2*W + 2*L

in this case we know that:

P = 125

W = 15

Replacing these in the perimeter equation we get:

125 = 2*15 + 2*L

125 = 30 + 2*L

125 - 30 = 2*L

95 = 2*L

95/2 = L = 47.5

Now we know that the daily record has a scale factor of 60%.

This means that each measure of this rectangle is (60%/100%) times the equivalent measure of the rectangle garden.

Then if the width of the daily record is W' and the length of the daily record is L'

This means that:

L' = (60%/100%)*L = 0.6*L = 0.6*47.5

W' = (60%/100%)*W = 0.6*W = 0.6*15

Then the perimeter is:

P' = 2*0.6*47.5 + 2*0.6*15 = 75

(notice that is exactly the same than multiplying the original perimeter by (60%/100%) = 0.6)

Solve for the variable

Answers

Answer:

v= 25

Step-by-step explanation:

Try to isolate the variable by getting rid of the 5. Multiply both sides of the equation by 5 to cancel out the 5 on the left side. You are left with 7v= 35(5). Simplified it is 7v= 175. Then to get the v alone, you need to divide both sides by 7 to cancel out the 7 on the left side. You are left with v= 175/7.

This is v= 25

If CA= 4x and CB= 8x-12 , what is the length of CA ?

Answers

Answer:

Step-by-step explanation:

CA and CB are both opposite equal 90 degree angles so are equal so we can say

4x-12=0

4x=12

x=3, since CA=4x

CA=4(3)=12

Artie, Len, Gina, and Wen divided a carton of baseball cards as shown in the circle graph above. If Wen's
share was 60 cards, what was Gina's share of the cards?
25
50
100
200

Answers

Answer:

Step-by-step explanation:

Wen: 30% of the total number of cards = 60 cards

Set this up as an equation

30/100 = 60/x

Cross multiply

30 × x = 100 × 60

30x = 6000

Divide both sides by 30 to isolate the variable

x = 200

There are 200 cards total

Gina: 25% of the total 200 cards

Set this up as an equation

25/100 = x/200

Cross multiply

25 × 200 = 100 × x

5000 = 100x

Divide both sides by 100 to isolate the variable

50 = x

Gina's share is 50 cards

Probability of blue is 0.4 red 0.3 yellow 0.3 there are 30 blue cubes in box what total number of cubes in box

Answers

Answer:

Step-by-step explanation:

The computation of the total number of cubes in box is shown below:

Given that

The probability of blue = 0.4

For red it is 0.3

And, for yellow it is 0.3

As if there is 30 blue cubes in a box

So for red it is = 30 × 0.3 ÷ 0.4 = 22.5

And, for yellow = 30 × 0.3 ÷ 0.4 = 22.5

Now the total number of cubes in a box is

= 30 + 22.5 + 22.5

= 75
