Answer:

C, E

Step-by-step explanation:

The unit rate represented by the point (x, y) is y/x. To find which rates are lower than 3/5, we can find the difference ...

... 3/5 - y/x

If that difference is positive, then the rate represented by the table is lower.

That difference is ...

... (3x -5y)/(5x)

Since we're only interested in the sign, we only need to compute the numerator value.

A. 3·3 -5·4 = -11 . . . . . the table has a higher rate

B. 3·5 -5·4 = -5 . . . . . the table has a higher rate

C. 3·31 -5·18 = 3 . . . . the table has a lower rate

D. 3·18 -5·11 = -1 . . . . the table has a higher rate

E. 3·12 -5·7 = 1 . . . . . the table has a lower rate

Choices C and E are appropriate.

1. Find Angle A :

$x + 24 = 3x$

$3x - x = 2 4$

$2x = 24$

$x = 12$

Angle A :

$3x$

$3 \times 12$

$36 \degree$

2. Find Angle B :

$10x - 27 = 7x$

$10x - 7x = 27$

$3x = 27$

$x = 9$

Angle B :

$10x - 27$

$(10 \times 9) - 27$

$90 - 27$

$63 \degree$

Find Angle C :

$5x + 1 = 6x - 13$

$6x - 5 x = 1 + 13$

$x = 14$

Angle C :

$5x + 1$

$(5 \times 14) + 1$

$70 + 1$

$71 \degree$

Find Angle D :

$6x + 3 = 4x + 39$

$6x - 4x = 39 - 3$

$2x = 36$

$x = 18$

Angle D :

$4x + 39$

$(4 \times 18) + 39$

$72 + 39$

$111\degree$

And it's given :

36° = Angle A = B

63° = Angle B = A

71° = Angle C = H

111° = Angle D = E

Therefore, the answer will be " BAHE "

Suppose that y varies directly with x and y=12 when x=-2. What is x when y=-6<br> Please help me!!

hodyreva [135]

Answer:

x = 1 because when you multiply negative 2 by negative six you get twelve. when you multiply positive one by negative six you get negative six.

At Dave's diner, 2 sandwiches and 2 drinks cost $12. You can buy 5 drinks for the cost of one sandwich.

hram777 [196]

If you’re asking for the cost of the drink, the drink would be $1. This is because 2 sandwiches would cost $10 and that means 1 sandwich would make it $5. If 2 sandwiches cost $10, the remaining $2 in the $12 dollars would be the drinks. 2 drinks for $2 would make 1 drink for $1. So the cost of 5 drinks is $5 or $1 per drink.

If confused, don’t be shy to ask :)

HELP: Part A: Using computer software, a correlation coefficient of r=0.51 was calculated. Based on the scatter plot, is that an

user100 [1]

Answer:

Part A: YES, it is.

Part B: the amount of pumpkin picked and the amount of fertilizer applied.

Step-by-step explanation:

Part A:

The closer the correlation coefficient is to 1, the stronger the relationship between two variables, and vice versa. Also, the closer the data points are on a scatter plot, the closer the correlation coefficient is to 1.

The scatter plot shown indicates a positive correlation between number of days and number of pumpkins. However, the data points are to some extent farther apart from each other. This shows a moderate relationship between the two variables. Therefore, a correlation coefficient, r, of 0.51 that was calculated can be concluded to be accurate , because an r of 0.51 depicts a moderate relationship between two variables.

Part B:

A variable that could affect the number of pumpkins picked could be amount of fertilizer applied, instead of the day in October. Thus, we can compare the amount of pumpkin picked and the amount of fertilizer applied.
