You are remodeling your kitchen. You have contacted 2 tiling companies who gladly told you how long it took their workers to tile a floor of a similar size. Jim completed 1/2 the floor in 12 hours, Pete completed the other 1/2 in 10 hours. If Pete can lay 25 more tiles per hour than Jim, what equation would you use to find the rate that Jim can lay tiles? Let x represent Jim's rate.

A. 10x = 12 (x -25)
B. 12x = 10 (x + 25)
C. 10x = 12 (x + 25)
D. 12x = 10 (x - 25)

Answer: $15.00

Step-by-step explanation: If 3 sodas cost you $4.50 then you divide it by 3 to get $1.50 per soda. Then you multiply the number by ten to get $15.

Answer:

45 $

Step-by-step explanation:

basically take 4.50 and take the decimal point out and then multipy by ten.

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

let the number be n , then

4 - 4n = 2n ( add 4n to both sides )

4 = 6n ( divide both sides by 6 )

[tex]\frac{4}{6}[/tex] = n

The number is [tex]\frac{2}{3}[/tex]

Answer:

Let the number = x

4 - 4x= 2x

4 = 2x+4x

4 = 6x

x = 4/6

x = 2/3

Answer:

y = (1/2)x + 7/2

Step-by-step explanation:

y = ax + b (general form of a linear function)

a = 1/2 (slope)

y = (1/2)x + b

(-3, 2) is on the line, 2 = (1/2)*(-3) + b

2 = -3/2 + b

b = 2 + 3/2

b = 7/2

equation: y = (1/2)x + 7/2

Answer:

60

Step-by-step explanation:

To find the mean, add all numbers together and divide by the amount of numbers.

Total of number = 660

Number of numbers = 11

660/11 = 60

Answer:

The median is 70.

Step-by-step explanation:

I believe you may have mixed up median with mode.

Here are the definitions of both:

Mode - The value that appears the most in a data set

Median - The middle number in a list of numbers ordered from least to greatest

To find the median of this data set, we must arrange the numbers from least to greatest!

20, 20, 30, 50, 60, 70, 70, 80, 80, 90, 90

Now we just have to figure out the middle number...which is 70!

20, 20, 30, 50, 60, 70, 70, 80, 80, 90, 90

I hope this helps! Let me know if you have any other questions :D

Step-by-step explanation:

The angles of rectangle add up to 360°

So the missing angle + 65 + 110 + 87 = 360

The missing angle + 262 = 360

The missing angle = 98°

please give me a brainliest answer

Step-by-step explanation:

? + 65°+ 110°+87° = 360°

? + 262° = 360°

? + 262 -262° = 360° - 262°

? = 98°

Answer:

Step-by-step explanation:

From your knowledge of multiplication tables, you know ...

  48 = 6·8 = 3·2·2·2·2 = 3·2^4 . . . . a = 4

  56 = 7·8 = 7·2·2·2 = 7·2^3 . . . . . . b = 3

Answer:

C

Step-by-step explanation:

Divide the Y values by the X values to check your answer

Answer:

C

Step-by-step explanation:

The question asks for a 0.3 constant of proportionality between 'x' and 'y'.

So, if you multiplied 0.3 to the number in 'x', you would get the number in 'y'.

By process of elimination, we can find that in A, 0.3 * 6 is not 2 and it's the same for all the other numbers in the table.

For B, 3*0.3 is not 1.8 and 0.3 multiplied by the other numbers in B do not match the number in y.

The only answer that matches is C, 4*0.3 is 1.2, 8*0.3 is 2.4, and 13*0.3 is 3.9.

So, the answer is C.

Step-by-step explanation:

did you do tangent?

if so

you know that:

you needed to use a scientific calculator and use the TAN button

formula:

Tan 60=100/x

if not

you could measure but it might not have been exact and you should just use the calculator

i think you just put -4 into the x's and solve

Answer:

[tex] \sqrt{54} = \sqrt{9 \times 6} = 3 \sqrt{6} [/tex]

Answer:

x=55*

y=125*

Step-by-step explanation:

In parallel lines, opposite angles are equal to each other so x=55.

In lines, adjacent (side by side) angles always add up to 180 so,

x+y=180

55+y=180

y=180-55

y=125

Answer:

6,500

Step-by-step explanation:

Discount = 20%

Therefore the cost price is 100 - 20 = 80%

so,

£5,200 = 80%

To find the 100% ( the cost of the car before the discount), invert the fraction.

100/80 x 5200/1 = 6,500

Answer:where is the answer?
