They give you: <RSP = 90 degrees

If you look in the diagram, <RSP is vertical to <UPW and vertical angles have the same measure. <RSP = <UPW

So the correct answer is A.

I was doing my khan and i got stuck<br> 6=2(y+2)

Anna [14]

Answer:

$y=1$

Step-by-step explanation:

Given:

$6=2(y+2)$

Distribute the parenthesis

$6=2y+4$

Subtract both sides by 4

$2=2y$

Divide both sides by 2 to get $y$ alone

$1=y$

there are 30 marked seals. In a survey, you count 58 seals, 16 of which were marked. About how many seals are in the area? Round

Rina8888 [55]

Answer:

109 seals

Step-by-step explanation:

Let

x -----> approximate total seals in the area

we know that

In a survey, you count 58 seals, 16 of which were marked

Using proportion

Find out how many seals are in the area , if there are 30 marked seals

$\frac{58}{16} =\frac{x}{30}\\\\x=58(30)/16\\\\x=108.75\ seals$

Round to the nearest whole number

$108.75\ seals=109\ seals$

2.33(3.56) what is the division problem

RSB [31]

Answer:

Step-by-step explanation:Perhaps somebody's asked this already, but I can't see it. Suppose I have a square that is 7 feet by 7 feet. I want to calculate the area. I multiply 7 feet by 7 feet and get 49 square feet, but since the lowest number of sig figs in one of my operands is one, my answer can only have one sig fig. This forces my answer to be 50 square feet, and I have now lost precision. Can somebody explain this?

The measure of an angle is 8 degrees less than three times the measure of another angle. If the two angles are supplementary, wh

OLga [1]

Let x and y be the angles
X= 3•y-8
X+ y = 180
Substitute first relationship in second
3y-8+y=180
4y=180+8
Y =188/4= 47 degrees
X= 180-47=133 degrees
The measure of the large angle is
133 degrees
