CAN SOMEONE PLEASE HELP ME ASAP PLEASEE ANYBODY LITERALLY ANYONE OUT THERE PLEASE. Determine m∠ABQ and determine m∠BCR.

Answers

Answer 1

Answer:

Answer:

ABQ = 139

BCR is the same as QBC since they are alternate interior angles

BCR = 41

Step-by-step explanation:

CBQ and SCB are same side interior angles so they add to 180

2a-9 + 5a +14 = 180

Combine like terms

7a +5 = 180

Subtract 5 from each side

7a = 175

Divide by 7

7a/7 = 175/7

a = 25

ABQ is the same as SCB since they are corresponding angles so

ABQ = SCB = 5a+14 = 5*25+14 = 125+14 = 139

BCR is the same as QBC since they are alternate interior angles

BCR = QBC = 2a-9 = 2*25 -9 = 50-9 = 41

What is the missing value? The Volume is 5120 m^3

Answers

I think that the missing value is 16m.

I just multiplied two other numbers with 20 and 20 x 16 x 16 = 5120

I hope this was right.

Answer:

Step-by-step explanation:

V= $\pi$ r^2

5120= $\pi r^(2)$ x20

5120/20 = 256

$√(256)$ =16

16+16 ( 16x2) = 32

How do you find the slope

Answers

Remember that the slope of a line never changes, so you can choose whatever 2 points you want and you will always get the same slope. Calculate the rise and run (You can draw it on the graph if it helps). The slope is 2/4, which , of course, you can simplify to ½.

Answer:Use the slope formula, m=y2-y1/x2-x1

Step-by-step explanation:

Which equation describes the same line as y – 3 = –1(x + 5)?A. y = –1x – 5
B. y = –1x – 2
C. y = –1x – 1
D. y = –1x + 8

Answers

Answer:

Option B is correct.

$y= -1x-2$

Step-by-step explanation:

The distributive property says that:

$a \cdot (b+c) = a\cdot b+ a\cdot c$

Given the equation of line:

$y-3 = -1(x+5)$

Apply the distributive property we have;

$y-3 = -1x-5$

Add 3 to both sides we have;

$y-3+3= -1x-5+3$

Simplify:

$y= -1x-2$

Therefore, an equation describes the same line as y – 3 = –1(x + 5) is, $y= -1x-2$

y – 3 = –1(x + 5)

y - 3 = -x - 5

y = -x - 5 + 3

y = -x - 2

answer is B. y = –1x – 2

Which expression correctly represents “three less than the product of a number and two, increased by five”?

Answers

Answer:

Let x represents the number.

Given the statement: "Three less than the product of a number and two, increased by five".

"Product" means multiply

"Product of a number and two" translated to $2x$

"Three less than the product of a number and two" translated to 2x - 3

Increased by 5 means +5

then;

the given statement becomes;

$(2x-3)+5$

Therefore, the expression that represents "three less than the product of a number and two, increased by five" is $(2x-3)+5$

Answer: 3 - (2n+5)

Use the Law of Sines to solve the following triangle. Approximate your answers to the nearest tenths. c = 10.2 in, A = 45.1° B = 75.8°

Answers

law of sines says
a/sinA=b/sinB=c/SinC
where a,b,c are sides of a triangle and A,B,C are angles respectively.
a/sin45.1=c/sin59.1

(we can find angle C by sum of angles of a triangle is 180.)

a=sin(45.1) x 10.2/sin (59.1)

a=0.708 x 10.2/0.85
a=8.496
a=8.5 units

now u can find b and c sides.
