A cyclist sprinter does 1200 J of work in a race. While her bike does 800 J of work
during the race. What is the efficiency of the bike?

Answer:

16

Step-by-step explanation:

First, let's find 64% of 25. We do this and get:

[tex]\frac{64}{100}\cdot25=\frac{1600}{100}=16. \text{ so our answer is \boxed{16 \text{ problems are true}}}[/tex]

~Plug the values :

⟶ [tex] \large{ \tt{(x - 4)(4x - 2)}}[/tex]

~ To multiply a binomial by a binomial , Firstly use the distributive property to multiply each term of the first binomial by each term of second binomial.

⟶ [tex] \large{ \tt{x(4x - 2) - 4(4x - 2)}}[/tex]

⟶ [tex] \large{ \tt{4 {x}^{2} - 2x - 16x + 8}}[/tex]

~Simplify

⟶ [tex] \large{ \tt{4 {x}^{2} - 18x + 8}}[/tex]

Answer:

3ab+(c^2)/a

you can't really solve this because g and r is not in the equation.

Answer:

using Pythagoras theorem 11/2 is the largest side so let a=9/10 b=11/5 c=11/2

a²+b²=c²

(9/10)²+(11/5)²=(11/2)²

81/100+121/25=121/4

lcm of 25 and 100 =100

(81+484)/100=121/4

565/100=121/4

113/20=121/4

since they are not equal therefore it's not a right angle triangle

Answer #1:

X= 75

Y= 15

Step-by-step explanation: The first equation is x+y=90 and then your next equation is x=5y. After you have those two equation you sub them in 5y+y=90 and once you solve for y you solve for x.

Answer:

One way to solve the quadratic equation x2  = 9 is to subtract 9 from both sides to get one side equal to 0: x2  – 9 = 0. The expression on the left can be factored:

(x + 3)(x – 3) = 0. Using the zero factor property, you know this means x + 3 = 0 or x – 3 = 0, so x = −3 or 3

Answer:

1.7

Step-by-step explanation:

To find the distance between two coordinates, use the formula [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex].

y2 = 4, y1 = 9, x2 = -1, x1 = 2

Insert the values into the equation:

[tex]\frac{4-9}{-1-2}[/tex]

Simplify:

[tex]\frac{4-9}{-1-2}= \frac{-5}{-3}=\frac{5}{3}[/tex][tex]\frac{}{} =1.7[/tex]

The distance between (2, 9) and (-1, 4), rounded to the nearest 10th, is 1.7.

Have a nice day!

Answer:

22.72 %

Step-by-step explanation:

There are 5 sixth graders over a  total of 5+8+9 = 22 students. Therefore the percent of sixth graders would be:

5/22 * 100 ≈ 22.72 %

P = a + b + c =4.81 + 8.8 + 8.42 = 22.03

Answer: option 3

Step-by-step explanation:

Answer:

d

Step-by-step explanation:

Answer:

x= -1 and y= -1

Step-by-step explanation:

Answer:

(-1,-1)

Step-by-step explanation:

-6x+5y=1

6x+4y=-10

Add the two equations together to eliminate x

-6x+5y=1

6x+4y=-10

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

9y     = -9

Divide by 9

9y/9 = -9/9

y= -1

Substitute back into one of the equations to find x

-6x+5y=1

-6x +5(-1) = 1

-6x -5 = 1

Add 5 to each side

-6x -5+5 = 1+5

-6x = 6

Divide by -6

-6x/-6 = 6/-6

x = -1

(-1,-1)

Answer:

169

Step-by-step explanation:

13*13=169

Answer:

169

Step-by-step explanation:

length x width = area

since it is a square, all sides are equal.

13 x 13 = 169

Answer:

Step-by-step explanation:

Hi!

Here is your answer,

I will explain in step by step,

[tex] {x}^{9} = {12}^{2} \times {12}^{7} [/tex]

Here we can simplify this further using this law,

[tex] {a}^{m} \times {a}^{n} = {a}^{m + n} [/tex]

So we will get,

[tex] {x}^{9} = {12}^{7 + 2} \\ {x}^{9} = {12}^{9} [/tex]

Since the powers are same we can cancel it out and we will get,

[tex]x = 12[/tex]

its 3/8 because she has eaten 2/8+3/8=5/8 and 8/8-5/8=3/8 is left

Answer:

A= 120  

b=200 (if the number on the bottom is a 4 thats cut out)

Step-by-step explanation:

for volume u just multiply the 3 numbers it gives u for the models like for example in the picture u do

6*4*5 in no specific order

if its a triangle and volume or area u do that but at the end divide by 2 in area

Answer:

6 511 104 in³

Step-by-step explanation:

Since we have 1 crate and 8 boxes fit into one crate.

So, volume of one crate, V' = 8 × volume of 1 box, V

Since the box is a rectangular prism of sides 2512 inches high, 18 inches long, and 18 inches wide, its volume, V = lwh where l = length of prism, h = height of prism and w = width of prism.

So, V = lwh = 18 in × 18 in × 2512 in = 813 888 in³

So, V' = 8 × 813 888 in³ = 6 511 104 in³

So, the minimum volume of the crate is 6 511 104 in³
