<h2>Answer:</h2>

The least number of consecutive shots Mario must make to increase his percentage from 60% to at least 70% is:

                                    4

<h2>Step-by-step explanation:</h2>

Mario makes 6 free throw shots out of his first 10 attempts.

The percentage is: 60%

  • Now if she make 1 more shot at the 11th attempt then the percentage will be:

\dfrac{7}{11}\times 100=63.63\%

( Since out of total 11 attempts she made 6 free throw before and 1 more at 11th attempt )

  • If she makes 2 consecutive shot after 10 attempts then the percentage will be:

             \dfrac{8}{12}\times 100=66.67\%

 Similarly,

  • If she makes 3 consecutive shot after 10 attempts then the percentage will be:

             \dfrac{9}{13}\times 100=69.231\%

                  which is still less than 70%

  • Now if she makes 4 consecutive attempts in the 4 throws after 10 attempts then,

               Percentage will be:

                 \dfrac{10}{14}\times 100=71.429\%

                Hence, the percentage is atleast 70%

Hence, he has to make 4 consecutive shots to increase his percentage to atleast 70%.

Answer pleaseeeeeeeeee
katovenus [111]

Answer:

y=-\frac{8}{7}x+4

Step-by-step explanation:

A line is perpendicular to another if its slope is the negative reciprocal of the other.

Your lines are in slope intercept form here, y=mx+b, where m is the slope. We can see the given line has slope \frac{7}{8}. The negative reciprocal of that is -\frac{8}{7}, which is the slope of the third answer choice.

A store sells flower arrangements at a cost of $28 each. Which statements are true regarding the price of the arrangements? Chec
Maru [420]

Let's check each case to determine the solution to the problem.

we know that

The cost of each flower  arrangements is \$28

Statements

<u>case A)</u> If the price is marked down by 10 percent, the new price will be \$25.20

we know that

If the price is marked down by 10 percent

then

the new price will be

10\%= \frac{10}{100} =0.10  

(1-0.10)*\$28=0.90*\$28 \\= \$25.20

\$25.20=\$25.20

therefore

The statement case A) is True

<u>case B)</u> If the price is marked down by 25 percent, the new price will be \$21

we know that

If the price is marked down by 25 percent

then

the new price will be

25\%= \frac{25}{100} =0.25  

(1-0.25)*\$28=0.75*\$28 \\= \$21

\$21=\$21

therefore

The statement case B) is True

<u>case C)</u> If the price is marked down by 50 percent, the new price will be \$19

we know that

If the price is marked down by 50 percent

then

the new price will be

50\%= \frac{50}{100} =0.50  

(1-0.50)*\$28=0.50*\$28 \\= \$14

\$14 \neq \$19

therefore

The statement case C) is False

<u>case D)</u> If the price is marked down by 35 percent, the new price will be \$18.20

we know that

If the price is marked down by 35 percent

then

the new price will be

35\%= \frac{35}{100} =0.35  

(1-0.35)*\$28=0.65*\$28 \\= \$18.20

\$18.20=\$18.20

therefore

The statement case D) is True

<u>case E)</u> If the price is marked down by 40 percent, the new price will be \$29.80

we know that

If the price is marked down by 40 percent

then

the new price will be

40\%= \frac{40}{100} =0.40  

(1-0.40)*\$28=0.60*\$28 \\= \$16.80

\$16.80 \neq \$29.80

therefore

The statement case E) is False
