Sam needs 7 1/2 cups of orange juice to make punch for a group of her friends. She only has 5 1/3 cups. Write and solve an equat

Solnce55 [7]

Answer:

Equation is $x+\frac{16}{3}=\frac{15}{2}$ where $x$ denotes number of cups of orange juice needed by Sam.

$x=\frac{13}{6}$

Step-by-step explanation:

Let $x$ denotes number of cups of orange juice needed by Sam.

Number of cups needed to make punch $=7\frac{1}{2} =\frac{15}{2}$

Number of cups with Sam $=5\frac{1}{3}=\frac{16}{3}$

Therefore,

$x+\frac{16}{3}=\frac{15}{2}\\\\x= \frac{15}{2}-\frac{16}{3}\\\\x=\frac{45-32}{6}\\\\x=\frac{13}{6}$

When homeowners list their home for sale, they begin by listing it for a price that is greater

Phantasy [73]

Answer:

-0.924

Step-by-step explanation:

The magnitude of the correlation coefficient is the square root of the variation.

|r| = √0.854

|r| = 0.924

The sign of the correlation coefficient is the same as the slope of the line of best fit. In this case, it's negative.

r = -0.924

Answer:

|x − 37,500| ≤ 4,500

Step-by-step explanation:

salary - 37,500 can be up +4500 or as negative -4500

as much as means less than or equal to

We use absolute values to indicate this

Unit 8: Right Triangles & Trigonometry<br> Homework 2: Special Right Triangles

Kamila [148]

Answer:

17. z=39/sin45= $78/\sqrt{2}$

y=39/tan60= $39/\sqrt{3}$

x=y/sin60= $78/\sqrt{3}$

19. x= $6\sqrt{3}/tan60$ =6

y=2x=12

z= $\sqrt{2}y=12\sqrt{2}$

Step-by-step explanation:

17.

because:sin45=39/z

so: z=39/sin45= $78/\sqrt{2}$

then: tan60=39/y

so: y=39/tan60= $39/\sqrt{3}$

last: sin60=y/x

so: x=y/sin60= $78/\sqrt{3}$

19.

because: tan60= $6\sqrt{3}$ /x

so: x= $6\sqrt{3}/tan60$ =6

then: sin30=x/y

so: y=x*sin30=2x=12

last: sin45=y/z

so: z=sin45*y= $\sqrt{2}y=12\sqrt{2}$
