Answer:

14.8

23.2

Step-by-step explanation:

a = 1.6, a = 4, a = 6.8

3a + 2.8 when a = 1.6

= 3(1.6) + 2.8

= 4.8 + 2.8

= 7.6

3a + 2.8 when a = 4

3(4) + 2.8

= 12 + 2.8

= 14.8

3a + 2.8 when a = 6.8

= 3(6.8) + 2.8

= 20.4 + 2.8

= 23.2

Leo is running a 5% mile race. It took him 2 minutes to run the first mile of the race. If Leo continues running at the
same pace, how many more minutes will it take him to finish the race?

Answers

Answer:

8 minutes

Step-by-step explanation:

Leo has already run 1 mile, leaving him with 4 more to finish the race. At 2 minutes a mile (a ridiculously impressive pace, considering the world record mile time is just a little under 3:45), it will then take him 4 x 2 = 8 minutes to cross the finish line.

81x^2+180x+100=81x

Answers

Answer:

There is no solution :/

Step-by-step explanation:

81x^2+180x+100=81x

Step 1: Subtract 81x from both sides.

81x^2+180x+100−81x=81x−81x

81x^2+99x+100=0

For this equation: a=81, b=99, c=100

81x^2+99x+100=0

Step 2: Use quadratic formula with a=81, b=99, c=100.

x= −b±√b2−4ac/ 2a

x= −(99)±√(99)2−4(81)(100) /  2(81)

x= −99±√−22599/162

So you see... no solution

Divide. Then check your answer using multiplication. Use paper to show you work. 745/82 Quotient=. Remainder=

Answers

Answer:

Quotient = 9

Remainder = 7

Step-by-step explanation:

Divide :

745 / 82

= 9 ; (82 * 9 = 738)

Remainder = 745 - 738) = 7

Hence to verify :

(82 * 9) + 7

738 + 7

= 745

Using direct division :

745 / 82 = 9.0853658

Answer:

figure one only

Step-by-step explanation:

Hey There!

To solve this one we are going to use the Pythagorean Theorem

The Pythagorean Theorem states that the two shorter sides squared equals the longest side squared

if this is true for the triangles then they are indeed right triangles

for figure 1...

[tex]6^2=36\\8^2=64\\36+64=100\\10^2=100\\100=100[/tex]

this is true therefore figure 1 is a right triangle

for figure 2

[tex]10^2=100\\12^2=144\\144+100=244\\14^2=196\\244\neq 196[/tex]

this is not true therefore figure 2 is not a right triangle

Given:

The dimensions of a box are 3ft, 3ft and 13 ft.

To find:

The length of the longest flagpole that could be shipped inside the box.

Solution:

We know that the length of longest flagpole that could be shipped inside the box is equal to the length of the diagonal.

[tex]Diagonal=\sqrt{l^2+b^2+h^2}[/tex]

Where, l is length, b is breadth and h is height.

[tex]Diagonal=\sqrt{(3)^2+(3)^2+(13)^2}[/tex]

[tex]Diagonal=\sqrt{9+9+169}[/tex]

[tex]Diagonal=\sqrt{187}[/tex]

[tex]Diagonal\approx 13.67[/tex]

Therefore, the longest flagpole that could be shipped is about 13.67 feet long.
