1/4 = 1/2 (r + 10)

pls help! i will give brainly

Answers

Answer:

The exact form is -19/2

Decimal form: -9.5

Mixed number form: -9 1/2

Step-by-step explanation:

Answer:

r = -9.5

Step-by-step explanation:

1/4 = 1/2(r + 10)

1/4 = 1/2r + 5

-5               -5

1/2r = -4 3/4

1/2 x 2/1 = -4.75 x 2/1 or (2)

r = -9.5

To check work:

1/4 = 1/2(-9.5 + 10)

1/4 = -4.75 +5

1/4 = 1/4

A circle has diameter of 11cm
A square has a side length of 7cm

Use Pythagoras Theorem to show that the square can fit into the circle without touching the edge of the circle.

Answers

In this case, to prove what is required, we must use the Pythagorean theorem to find the diagonal of the square.
If the diagonal of the square is smaller than the diameter of the circle, then the square will fit perfectly in the circle without touching it.
Diagonal = Root ((7 ^ 2) + (7 ^ 2)) = 9.89 cm.
we observed that
9.89cm <11cm.
Therefore we show that:
the square will fit inside the circle without touching the edge of the circle

The median of the data set is 81. What number is missing?

82, 87, _, 77, 70, 80, 88

Answers

Median is the middle number.
Rearrange the numbers to smallest to biggest.
70, 77, 80, _, 82, 87, 88
If the median of the data set is 81 the middle number needs to be 81.
So the missing number is 81.
70, 77, 80, 81, 82, 87, 88
it is 81 because well first you order the numbers from lowest to greatest then start crossing a number off from each side of the numbers until you get a equal amount crossed in each side there will be one number left that’s not crossed off and it will be 81

Answers

Answer:

156km

Step-by-step explanation:

red Maserati

speed= 120km/h

Time= 5h

distance= speed × time( see the formula pic)

= 120km/h × 5h

=600 km

green Ford Pickup

speed= 74km/h

Time= 6h

distance= speed ×time

=74km/h ×6h

=444km

difference

600-444=156km

156Km Because the red Maserati would go vroom vroom

First blank space: 4        Second blank space: 48              Third Blank Space: 48

Step-by-step explanation:

You have to multiply by 4 to get the denominator to 100. For the second blank space, it is asking what the numerator would be if the denominator were 100. It would be 48 because 12 x 4= 48. For the third blank space, 48/100 is 48%, so it would be 48.

Hope this helped!! :D

Answer:

Multiply the numerator and the denominator by 4 to get 48/100

You get 48%

Step-by-step explanation:

100 divided by 25 is 4 so that means you multiply the numerator by 4 and you get 48

how many solution does 4x-5(2x+1)=6x+1 have

Answers

The number of solution the equation 4x - 5 (2x + 1) = 6x + 1 have is one.

What is a solution?

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We have,

4x - 5 (2x + 1) = 6x + 1

4x - 10x - 5 = 6x + 1

-6x - 5 = 6x + 1

-5 - 1 = 6x + 6x

-6 = 12x

x = -6/12

x = -1/2

This means,

The equation has one solution.

Thus,

The equation has one solution.

The table and the graph each show a different relationship between the same two variables, x and y:

A table with two columns and 5 rows is shown. The column head for the left column is x, and the column head for the right column is y. The row entries in the table are 3,270 and 4,360 and 5,450 and 6,540. On the right of this table is a graph. The x-axis values are from 0 to 10 in increments of 2 for each grid line. The y-axis values on the graph are from 0 to 800 in increments of 160 for each grid line. A line passing through the ordered pairs 2, 160 and 4, 320 and 6, 480 and 8, 640 is drawn.

How much more would the value of y be in the table, than its value on the graph, when x = 11?

100
110
190
200

Answers

Answer:

110

Step-by-step explanation:

The answer is 110

If the function for the table is y=90x and the function for the graph is y=80x, then at x=11, the table would be at (11, 990) and the graph at (11, 880) meaning that the y value of the table would be 110 more than the y value of the graph.
