Answer:

Jack needs to run at a speed of 1/12 mph

Step-by-step explanation:

Mathematically;

speed = distance/ time

Distance = speed * time

10 minutes = 10/60 h = 1/6 hours

The distance to the school will be

Distance = 3 * 1/6 = 1/2 = 0.5 miles

Now, he needs to be at school 4 minutes earlier, time will now be 10 - 4 = 6 minutes

To get the speed here;

Recall that the distance from above does not change

So speed = 0.5/6 mph 0r 1/12 mph

Answer:

1.5 pounds of potato salad for 4.50 would be cheaper

Step-by-step explanation:

because if you divide 3.50 by two you get 1.75 and added back to 3.50 you can purchase 1.5 pounds for 5.25 which is more expensive than 4.50

Answer:

Mo's answer is wrong.

635 - 813

= -178

Step-by-step explanation:

a. Is Mo's answer right?

No, Mo's answer is incorrect

Mo did this by working from right to left, Just like Subtraction

• 3 - 5 =

We that 1 from the number in tens , add that to 3, making it 13

13 - 5 = 8

• 1 - 3 = 7

The one above becomes 0, because 1 was taken from it. We add 1 to 0, making it 10

10 - 3 = 7

• 8 - 6 = 1

The 8 above reduces to 7 because 1 has been taken from 8.

Hence: 7 - 6 = 1

635 - 813

= -178

The answer is minus 178 because, we are subtracting the bigger number form the smaller number.

b. Solve

6(100) + 3(10) + 5(1)

- [8(100) + 1(10) + 3(1)]

by working with expanded forms. Discuss how Mo's work compares with your work in expanded forms.

= -1(100) + 7(10) + 8(1)

The contrapositive of this statement would be: "If x does not equal -4, then 5x + 7 will not equal to -13."

The contrapositive is defined as the inverse and converse of a conditional statement.

X is equal to 4 we know this is because the sign in between the number means greater than or equal to so 3 x 4 equals 12 which makes the equation on right true and on the left x.

So, the contrapositive of this statement would be:

"If x does not equal -4, then 5x + 7 will not equal to -13."

#SPJ2

The answer is y = 12x - 24

Use the form y = mx + b

If the points are (2, 0) and (3, 12) the slope is 12 which gives us m.

Since every time you go backwards once it goes down 12, (1, -12) is a point and then (0, -24) is a point that shows us the y-intercept which gives us b.

Answer:

he is incorrect

Step-by-step explanation:

He is incorrect because 10 times 3 is 30, plus-minus 2 which is 30. So instead of 34, it is 30. or you can say Anthony is wrong. Following the order of operations, you would do the 10*3 first. Then, you would take the 30, and finish the equation from left to right. So you would add 2 to make it 32 and then subtract 2 to make it 30 again. So your final answer is 30, not 34. So Anthony is wrong.

Answer:

The next time she will have both meetings on the same day again is 24 days time

Step-by-step explanation:

The given information are;

The frequency of the Junior Optimist club meeting = Every 3 days

The frequency of the Drama club meeting = Every 8th day

The club meeting Anna will attend today = Both meetings

The next time she will have both meetings on the same day again is given as follows;

The next time she will have both meetings on the same day again = The number of days the complete cycles of both meetings will coincide = The product of the cycles of both meetings

The next time she will have both meetings on the same day again = 8 × 3 = 24 days

The next time she will have both meetings on the same day again = 24 days time.

Answer:

pls 5 star

Step-by-step explanation:

8 taps can fill a tank in 27 minutes.

So,  

1 tap can fill the same tank in time = 27 × 8 = 218 minutes

Therefore, 6 remaining taps can fill the same tank = 216/6

= 36 minutes  

The remaining 6 taps will take 36 minutes to fill the same tank.

Answer:

Options 1,2,3 are correct statements

The first values in an ordered pair ( the coordinates) are the domain : ( -3,-2,-1,0,1)

The second values are the range : (-1,1,2,3,4,5)

One input should have only one output for a function.

But -1 input has 2 outputs: -1 and 3.

Thus, it is a relation and not a function.

Hope it helps :)

36 i think

Step-by-step explanation:

16 divided by 4 is 4

36 divided by 4 is 9

4*9=36

Answer:

324 square inches

Step-by-step explanation:

1/4 of 16 = 4

16-4 = 12

1/4 of 36 = 9

36-9 = 27

A= l*w

A= 27 x 12

A= 324 square inches

Answer:

B

Step-by-step explanation:

90+45+45=180

All triangles equal 180.

Its B because if one angle is 90° then the other angles will equal each other. It cant be 60° and 30° because they dont equal, so your final answer is B.

Answer:

Maggie is 7 years old

Step-by-step explanation:

m+2m-4=17

3m-4=17

3m=21

m=7

Answer:

Maggie is seven years old

Step-by-step explanation:

Maggie's Brothers Age = B

Maggie's Age = M

2M - 4 = B

B + M = 17

Plug in 2M - 4 for B

( 2M - 4 ) + M = 17

Combine Like Terms

3M - 4 = 17

Add 4 to either side

3M = 21

Divide either side by 3

M = 7

Check your answer

2M - 4 = B -> 2 x 7 - 4 = B -> 14 -4 = B -> B = 10

B + M = 17 => 7 + 10 = 17 => 17 = 17

Answer:

The second one.

Step-by-step explanation:

Both intercept twice at 0 and -4.

Answer:

You subtracted 25 from both sides.

Step-by-step explanation:

To move one part of the equation to the other side, you need to do the opposite. 25 is already negative(or being subtracted) so you need to add it to both sides to cancel it out on the left.

10x=-75+25

10x=-50

then divide both sides by 10

x=-5

Answer:

4.50 i think

Step-by-step explanation:

a product that normally costs $25 with a 18 percent discount will cost you $20.50, and you saved $4.50. You can also calculate how much you save by simply moving the period in 18.00 percent two spaces to the left, and then multiply the result by $25 as follows: $25 x . 18 = $4.50 savings.

Answer:

4.5

Step-by-step explanation:

you multiply 18 and 25 to get an answer of 450 then divided it by 100 to get 4.50

Answer: Corn = 200 acres

Wheat= 400 acres

Step-by-step explanation:

Let the number of acres of corn = c

Let the number of acres of wheat = w

The Mulder Farm has 600 acres of land allotted for raising corn and wheat. This will be:

c + w = 600

c = 600 - w

Cultivation cost equals:

= 40c + 25w = 18000

Since c = 600 - w, we slot it into the equation

40c + 25w = 18000

40(600 - w) + 25w = 18000

24000 - 40w + 25w = 18000

Collect like terms

24000 - 18000 = 40w - 25w

6000 = 15w

w = 6000/15

w= 400

400 acres of wheat will be planted

Since c + w = 600

c = 600 - 400

c = 200

200 acres of corn should be planted

Answer:

(- ∞, - 1 )

Step-by-step explanation:

Given

4(x + 2) < - [tex]\frac{1}{2}[/tex] (4x - 4) ← distribute parenthesis on both sides )

4x + 8 < - 2x + 2 ( add 2x to both sides )

6x + 8 < 2 ( subtract 8 from 2 )

6x < - 6 ( divide both sides by 6 )

x < - 1

x ∈ (- ∞, - 1 ) ← in interval notation
