If the team’s average time is less than one minute per leg, then the eighth graders earn 50 points. If not, the seventh graders earn 50 points. Which grade should be awarded 50 points?

Answer:

seven eights of a number = 7/8 × a number

let the unknown number be = x

[tex] \frac{7}{8} \times x = 63[/tex]

[tex]x = 63 \div ( \frac{7}{8} )[/tex]

[tex]x = 63 \times \frac{8}{7} [/tex]

[tex]x = \frac{504}{7} [/tex]

[tex]x = 72[/tex]

The components of an integer division are dividend, divisor, quotient and a remainder.

The expressions with quotient 7R12 are: 362 ÷ 50 and 432 ÷ 60

Start by testing the options

[tex]\mathbf{362 \div 50}[/tex]

50 can divide 362 in 7 places and a remainder of 12.

So:

[tex]\mathbf{362 \div 50 = 7\ R\ 12}[/tex]

[tex]\mathbf{492 \div 50}[/tex]

50 can divide 492 in 9 places and a remainder of 42.

So:

[tex]\mathbf{492 \div 50 = 9\ R\ 42}[/tex]

[tex]\mathbf{420 \div 60}[/tex]

60 can divide 420 in 7 places and without a remainder

So:

[tex]\mathbf{420 \div 60 = 7}[/tex]

[tex]\mathbf{408 \div 60}[/tex]

60 can divide 408 in 6 places and with a remainder of 48

So:

[tex]\mathbf{408 \div 60 = 6\ R\ 48}[/tex]

[tex]\mathbf{502 \div 70}[/tex]

70 can divide 502 in 7 places and a remainder of 12.

So:

[tex]\mathbf{502 \div 70 = 7\ R\ 12}[/tex]

Hence, the expressions with quotient 7R12 are: 362 ÷ 50 and 432 ÷ 60

Answer:

c) slope= 5 y-intercept=12

Step-by-step explanation:

first you use y2-y1 divided by x2-x1 to find slope

32-22 10

——— = — = 5

4 - 2 2

then you plug what you know into point-slope-form

y-22=5(x-2)

y-22= 5x-10

y= 5x+12

Could you give brainliest

Yes, to break a 2-digit number into tens and ones it is a simple process. To do it you have to take a number, let's say, 56. We can take the 5, because it has one digit to the right of it, we add one 0 to the right of it. Then we do the 6, which has nothing to the right, so we don't put anything there. 50 and 6. 5 tens and 6 ones.

I'm pretty sure that's the only way. If anyone knows otherwise, please post in the comments.

The answer would be D I believe.

Step-by-step explanation:

The -2's and the x = 2 so they should be equivalent. But I dont know :/

Answer:

The answer would be C

Step-by-step explanation:

C is the only one that have the same numbers on both sides.

A would be 2x+10=2x-10

B would be -2x-10=2x-10

C would be -2x-10=-2x-10

D would be -2x+10=2x-10

Answer:

a 2 cm and 6 cm

Step-by-step explanation:

The product of the dimensions must be 12 cm². (All answer choices meet that requirement.)

Opposite sides of a rectangle are the same length, so the sum of the two dimensions must be half the perimeter, 8 cm. The sums of the answer choices are ...

8 cm

7 cm

9.5 cm

13 cm

Only the first answer choice meets the requirement for a perimeter of 16 cm. The dimensions could be 2 cm and 6 cm.

Answer:

A. 2 cm and 6 cm 6*2=12 (area)

2+2+6+6=16

Answer:

In the given expression the constant of proportionality is  k = 8.

Step-by-step explanation:

The quantity P is said to be directly proportional to Q if they vary in proportion to each other.

Here, P ∝ Q ⇔  P = kQ : k = Proportionality Constant

Now, here given y ∝ x   and x =  -2, y = -16

Now, y ∝ x ⇒  y =  kxor, (-16)   = k (-2) or, k = 16/2  = 8 ⇒ k = 8So, for k = 8, y ∝ x 

Hence, in the given expression the constant of proportionality is  k = 8.

The best estimate for 6,193 ÷ 48 using compatible numbers is 120. Therefore, option B is the correct answer.

Given that, 6,193 ÷ 48.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Here, the number 6,193 can be rounded off to 6000 and the number 48 can be rounded off to 50.

So, 6,193 ÷ 48

= 6000 ÷ 50

= 120

The best estimate for 6,193 ÷ 48 using compatible numbers is 120. Therefore, option B is the correct answer.
