Helen's house is located on a rectangular lot that is 1 1/8 miles by 9/10. Estimate the distance around the lot.

Answers

Answer 1

Answer: You round 1 1/8 to 1 and 9/10 to 1 (since you are estimating) and then you add 1+1+1+1, which is 4 because to find perimeter you add the lengths and the widths together.

Answer 2

Answer:

Answer:You round 1 1/8 to 1 and 9/10 to 1 (since you are estimating) and then you add 1+1+1+1, which is 4 because to find perimeter you add the lengths and the widths.

Jennifer chooses a playing card at random from a deck of 52 cards then she chooses another one. What is the probability that she will get 2 cards that are hearts?

Answers

52 cards in a deck
4 suits
1/4 of 52 are hearts
1/4 of 52=13 cards

probability of getting 1 heart at first is 1/4

one card is taken out and assuming that it is the heart, 13-1=12,52-1=51
12/51

multiply
1/4 times 12/51=3/51=1/17

There is a $(13)/(52)$ chance she will pick a heart the first time and a $(12)/(51)$ that she will the second time.
The probability of this occurring thus is:
$(13)/(52)* (12)/(51) = (13*2*2*3)/(2*2*13*3*17)$
$= (1)/(17)$

Answers

$6a-12=8a$

$6a-8a=12$

$-2a=12$ ⇒ $a= (12)/(-2)$

$\boxed {a=-6}$

$6a-12=8a\n8a-6a=-12\n2a=-12\na=-6$

The formula for slope is:

slope=y2-y1/x2-x1 where (x1,y1) and (x2,y2) are points on the line

In this situation we know the x values of two points, and we know the slope, so we can solve for the missing y values.

slope=-7
(11,y1) (16,y2)

Now lets plug in the information into the formula.

slope=y2-y1/x2-x1
-7=y2-y1/16-11
-7=y2-y1/5
multiply both sides by 5
-35ft=y2-y1
distances cannot be negative so lets change -35ft to a positive number
35ft=y2-y1

The vertical distance between the two points is 35feet

Answer= A) 35ft

The graph of y=f(x) is shown below. find all the values of x where f(x)=8

Answers

Answer:

x = 4

Step-by-step explanation:

Find 8 on the y-axis. Draw a horizontal line through y =8. Determine the x value for which the graph intersects this horizontal line y = 8. It is x = 4

Select the correct answer from the drop-down menu. Consider the equations y = |x − 1| and y = 3x + 2.
The approximate solution of this system of equations is
