Answer 1

Answer:

8 = x

y = 29

Step-by-step explanation:

4x + 17 = y + 20 because vertical angles theorem.

y + 20 = 5x + 9  because interior angles theorem.

4x + 17 = 5x + 9  because same side interior angles theorem.

Subtract 9 from both sides and subtract 4x from both sides.

8 = x

Plug 8 in for x and solve.

5 times 8 is 40, plus 9 equals 49. Subtract 20 from both sides and you get 29.

5(8) + 9 = y + 20

49 = y + 20

29 = y

The measure of angle JLM is 140°. The measure of angle JKL is 75.

What is the measure of angle KJL

Enter your answer in the box.​

Answers

Answer:

KJL is 65 degrees

Step-by-step explanation:

If JLM is 140 deg. JLK is 40 deg  the two angles on transverse line must equal 180 total.

JKL being 75 degf, sum that with JLK of 40= 115 deg

180-115= 65 deg  Sum of interior angles on a triangle add up to 180 deg.

Answers

Answer: 3.25

Step-by-step explanation:

Sarah made a.mistaje when she was reducing 26 ÷ 8. It should be noted that 2 is a common factor to 26 and 8. Therefore 26÷2 = 13 and not 14 that Sarah wrote. Sarah should have written 13 ÷ 4 and not 14 ÷ 4.

26 ÷ 8 in decimal will give us 3.25

If c=g-4f, find trinomial that represents C when F=2x^2-5 and G=5x^2+x-3

Answers

Answer:

c = -3x² + x + 17

Step-by-step explanation:

c = g - 4f

f = 2x² - 5

g = 5x² + x - 3

c = (5x² + x - 3) - 4(2x² - 5)

c = 5x² + x - 3 - 8x² + 20

Sal places $500 in a retirement account that offers a return of 3.5% compounded annually . He will not deposit or withdraw any money from the account . Which function represents f(t) , the amount of money in the account after years a f(t) = 500 * (0.035) ^ t c. F(t) = 500 + 0.035t f(t) = 500 * (1.035) ^ t d. F(t) = 500 + 1.035t

Answers

Answer:

f(t) = 500 * (1.035) ^ t

Step-by-step explanation:

A = p(1 + r/n)^nt

Where

A = future value = ?

P = principal = $500

r = interest rate = 3.5% = 0.035

n = number of periods = 1

t = number of years = t

A = p(1 + r/n)^nt

= 500(1 + 0.035/1)^1*t

= 500(1 + 0.035) ^t

= 500( 1.035)^t

= 500 * (1.035)^t

f(t) = 500 * (1.035) ^ t

On a certain hot​ summer's 439 day, people used the public swimming pool. The daily prices are $1.75 for children and $2.50 for adults. The receipts for admission totaled $1021.00 How many children and how many adults swam at the public pool that​ day?

Answers

Answer:102 children and 337 adults swam at the publice pool that da

Step-by-step explanation:

let the number of children be x

and

the number of adults be y

such that the total number of people who came to use the public swimming pool be expressed as

x + y = 439----- Equation 1

and price  for swimming be expressed as

1.75x + 2.50y =1021----- Equation 2

Step 2

x + y = 439----- Equation 1

1.75x + 2.50y =1021----- Equation 2

First make x the subject formulae and put in equation 2

x= 439-y

1.75 (430-y) + 2.50y = 1021

Solving gives

768.25-1.75y+2.50y=1021

2.50y-1.75y=1021-768.25

0.75y=252.75

y =252.75/0.75  

y=337

To find x, put the value of y = 337 in equation 1

x+y= 439

x= 439-337

x=102

Therefore 102 children and 337 adults swam at the public pool that day

Bertha deposited $1000 into a retirement account when she was 18. How much will Bertha have in this account after 50 years at a yearly simple interest rate of 7.5%?

Answers

Answer:

$4750

Step-by-step explanation:

Simple interest is the interest calculated on the principal at a given rate for a time period.

The simple interest formula is given as,

SI = P x R x T / 100

P = principal

R = rate

T = time

Amount = SI + P

The amount Bertha will have in his account after 50 years is $4750.

What is simple interest?

Simple interest is the interest calculated on the principal at a given rate for a time period.

The simple interest formula is given as,

SI = P x R x T / 100

P = principal

R = rate

T = time

We have,

P = $1000

T = 50

R = 7.5%

A = SI + P

SI = (1000 x 7.5 x 50) / 100

SI = 1000 X 7.5 X 50 / 1000

SI = $3750

A = SI + P

A = 3750 + 1000

A = $4750

Thus,

The amount Bertha will have in his account after 50 years is $4750.

Answer:

n = 28°

Step-by-step explanation:

The angle at the centre is twice the angle on the circle subtended on the same arc.

Also angles subtended on the same arc are congruent , thus

m = n

Then

35 + m = [tex]\frac{1}{2}[/tex] (98 + n ) ← multiply both sides by 2 to clear the fraction

70 + 2m = 98 + n , but since m = n, then

70 + 2m = 98 + m ( subtract m from both sides )

70 + m = 98 ( subtract 70 from both sides )

m = 14 and n = 28

NourseChapter 1. Trouble Times TwoThe sun was glowing dull red as it slipped down behind the curving horizon of Mars, but Gregory Hunter was not able to see it.There was no viewscreen in the ship's cabin; it was too tiny for that. Greg twisted around in the cockpit that had been built just big enough to hold him, and shifted his long legs against the brace-webbing, trying to get them comfortable.He knew he was afraid ... but nobody else knew that, not even the captain waiting at the control board on the satellite, and in spite of the fear Greg Hunter would not have traded places at this moment with anyone else in the universe.He had worked too hard and waited too long for this moment.He heard the count-down monitor clicking in his ears, and his hands clenched into fists. How far from Mars would he be 10 minutes from now? He didn't know. Farther than any man had ever traveled before in the space of 10 minutes, he knew, and faster. How far and how fast would depend on him alone."All set, Greg?" It was the captain's voice in the earphones."All set, Captain.""You understand the program?"Greg nodded. "24 hours out, 24 hours back, 90 degrees to the ecliptic1, and all the acceleration2 I can stand both ways."Greg grinned to himself. He thought of the months of conditioning he had gone through to prepare for this run ... the hours in the centrifuge to build up his tolerance to acceleration, the careful diet, the rigorous hours of physical conditioning. It was only one experiment, one tiny step in the work that could someday give men the stars, but to Gregory Hunter at this moment it was everything."Good luck, then." The captain cut off, and the blastoff buzzer sounded.He was off. His heart hammered in his throat, and his eyes ached fiercely, but he paid no attention. His finger crept to the air-speed indicator, then to the cut-off switch. When the pressure became too great, when he began to black out, he would press it.But not yet. It was speed they wanted; they had to know how much acceleration a man could take for how long and still survive, and now it was up to him to show them.Fleetingly, he thought of Tom ... poor old stick-in-the-mud Tom, working away in his grubby little Mars-bound laboratory, watching bacteria grow. Tom could never have qualified for a job like this. Tom couldn't even go into free-fall for 10 minutes without getting sick all over the place. Greg felt a surge of pity for his brother, and then a twinge of malicious anticipation. Wait until Tom heard the reports on this run! It was all right to spend your time poking around with bottles and test tubes if you couldn't do anything else, but it took something special to pilot an XP ship for Project Star-Jump. And after this run was over, even Tom would have to admit it....There was a lurch, and quite suddenly the enormous pressure was gone.Something was wrong. He hadn't pushed the cut-off button, yet the ship's engines were suddenly silent. He jabbed at the power switch. Nothing happened. Then the side-jets sputted, and he was slammed sideways into the cot.He snapped on the radio speaker. "Control ... can you hear me?
