Find the solution to the system of equations below.

A:(7, 3)
B:(-3, 3)
C:(3, -3)
D:(2, -2)

Answer:

100 miles per hour.

Step-by-step explanation:

To solve this we need to divide 5 by 5 to find the answer for 1 hour rather than 5.

5 / 5 = 1

Following the logic of, “what you do to one side, you must do to the other” i will divide 500 by 5.

500 / 5 = 100

Mr B was traveling at 100 miles per hour.

(you should probably tell him to slow down haha)

Answer:

PB = 15

Step-by-step explanation:

A midpoint is a point in the center of a line. Since P is the midpoint of AB, the length of AP = PB. Therefore, if AP = 15, PB = 15.

Answer:

20 percent

Step-by-step explanation:

Because there are 160 total people, you would divide 32 by 160 which gives you 0.2 multiply 0.2 by 100 then you get 20 percent

32/160 = 0.2

0.2*100 = 20

Answer:

53.3%

Step-by-step explanation:

(32/63)×100

=53.3%

Answer:

probably of a head= 1/2

probably of a multiple of 3 (either 3 or 6)= 2ways*1/6 as 1/6 is the prob of any one side

Step-by-step explanation:

Answer:

1/12 or 8.3%

Step-by-step explanation:

To find probability, mark the how many sides you are testing in your probability over the possible outcomes.

Die: 1 side out of 6 sides is the test = 1/6 probability abt. 16%

Coin: 1 side out of 2 sides is the test = 1/2 probability 50%

To find total probability of getting a 5 on the die and a heads on the coin is found by multiplying the two fractions together.

1/6 x 1/2 = 1/12

abt. 16% x 50% = abt. 8%

Answer:

3

Step-by-step explanation:

Dilated has the meaning of getting larger. So in this case, if it has any meaning at all and the answer is "no answer given" then all you have to do is look at the y intercept.

The shorter line has a y intercept of 1

The longer line has a y intercept of 3

Therefore the dilation factor is 3

However if your teacher is a stickler for a better proof, then you could compare lengths.

Shorter line

Two end points

(-6,-3)     (6,5)

Distance = sqrt( (-6-6)^2 + (-3-5)^2 )

distance = sqrt (144 + 64)

distance = sqrt(208)

distance = 14.42

Longer line

(-12,-5)   (24,19)

distance = sqrt(24 - - 12)^2 + (19 - -5)^2 )

distance = sqrt( 36^2 + 24^2)

distance = sqrt (1296 + 576)

distance = sqrt(1872)

distance = 43.27

The best answer is =3

Answer:

Answer:

19 : 10 = 19 : 10

Solution:

Try to reduce the ratio further with the greatest common factor (GCF).

The GCF of 19 and 10 is 1

Divide both terms by the GCF, 1:

19 ÷ 1 = 19

10 ÷ 1 = 10

The ratio 19 : 10 cannot be reduced further by dividing both terms by the GCF = 1 :

This ratio is already in lowest terms.

Therefore:

19 : 10 = 19 : 10

Answer:

x=8

y= -6

Step-by-step explanation:

3(0)-4y=24

-4y=24

24÷-4

y = -6

----------------------

3x-4(0)=24

3x=24

24÷3

x = 8

to find the x-intercept, substitute the y for a zero "0", to find the y-intercept, substitute the x for a zero "0"

Answer:

x < 2

Step-by-step explanation:

8x -1 < 15

8x -1 (+ 1) < 15 (+ 1)

8x < 16

Answer:

d=3 1/4

Step-by-step explanation:

Answer: 3 1/4 or 37/4

Step-by-step explanation:

3 1/4 would have an extra fraction, subtracting would make both sides equal. 37/4 is 3 1/4 as an improper fraction instead of a mixed number.

Answer:

8. 504ft²

9. 4970yd² (rounded to 3 s.f.)  

Formulas (For easy reference):

Area of rectangle = length × breadth

Area of circle = pi×r×r

Circumference of circle = pi×r×2

-----------------------------------------------------------------------------------------------------------

Step-by-step explanation:

8. You know a box has 6 sides, and there are 3 types of surfaces that are different from each other, and you have to multiply each side by 2 cus there are the front and backside (You can draw the box with its dimensions to see the 3 types of surfaces and why I multiplied by 2):

(2×12×6) + (2×12×10) + (2×6×10) = 144 + 240 + 120

                                                   = 504ft²

9. The net of a cylinder contains two circles of radius 24yd and one long sheet to wrap around the circles with the length that is the circumference of the circle (so that it can wrap around the two circles) and a width which is the height of the cylinder (9yd).

2 Circles = 2×pi×24×24

                = 1152pi

Long sheet = 9×24×2×pi

                   = 432pi

Now we can add all of them together:

432pi+1152pi = 1584pi

                      = 4970yd² (rounded to 3 s.f.)

Answer:

Step-by-step explanation:

9.) Surface Area of Cylinders: A=2πrh+2πr^2

A=2πrh+2πr^2

A=2(3.14)(12)(9)+2(3.14)(12)^2

A = 678.24 + 904.32

A ≈ 1582.56

Answer:

the answer is 1

Step-by-step explanation:

Answer:

x=1

Step-by-step explanation:

for y²=4ax

directrix is x=-a

for y²=4x ,directrix is x=-1

for y²=4(x-2), shift directrix 2 units right.

so directrix is x=-1+2=1

so for (y+4)²=4(x-2) directrix is x=1

Answer:

Second choice, 4/3

Step-by-step explanation:

With the two point already highlighted, find the difference they have in x and y.  (-1, 2) and (2, 2)

x = -1 - 2 = -3

y = -2 - 2 = -4

The slope is y/x so it would be -4/-3 or just 4/3 because the negatives cancel each other out and they mean the same anyway.

An easier way would to just draw a slope triangle from the two points and count the squares they have. 4 squares going up and 3 squares going to the right = 4/3

Answer:

3 batches

Step-by-step explanation:

We have been given that a sports drink recipe calls for 5/3 tablespoons of powered drink mix for every 12 ounces of water.

We need to find out how many batches can be made with 5 tablespoons of drink mix and 36 ounces of water.

So, from the given information we see that to make 1 batch of sports drink we need 5/3 tablespoons of powdered drink mix for every 12 ounces of water.

So, we have 36 ounces of water. But we know that for 1 batch of sports drink we need to 12 ounces. So with 36 ounces of water we can make

= 3 batches

Therefore, we can make 3 batches of sports drink from 5 tablespoons of powdered drink mix and 36 ounces of water.
