The measurement of one angle of a right triangle is 42°. What is the measurement of the missing angle?

Answers

Answer 1

Answer: All triangles have 3 angles that add up to 180 degrees.
All right angle triangles have a 90 degree angle.
You have two angles, 90 and 42.
To find the last one, add 90 and 42. Then subtract that from 180 degrees.

90+42=132
180-132=48

Therefore, the missing angle is 48 degrees.

Answer 2

Answer:

Answer:

48°

Explanation:

42 + 90 = 132

because all triangle angles add up to 180°, then:

180 - 132 = 48°

Answers

Answer:

C. 1/10

Step-by-step explanation:

yes, it is in the thousands place, but it's comparing the 7 in the ten thousands place to the 7 in the thousandths place. If it said the 7 in the ten thousands is _____ the value of the 7 in the thousands place, the answer would be A. 10x.

10,000/10=1,000 so the answer is C. 1/10.

Math question6. Marla swims twice a week. Her equipment cost her $32.85 and she has a membership to the pool for $35 plus $3.50 per visit. She can walk to the pool, so transportation is free. How much will swimming cost her for the year?
(Points : 1)
$431.85
$249.85
$396.85
$492.75

Answers

Answer: Swimming will cost $431.85 for Marla (per year).

Step-by-step explanation:

Hi, to solve this we have to calculate how many weeks are in a year:

If a year has 365 days, we have to divide it by 7 ( the number of days in a week)

So: 365 / 7 =52.14 = 52 weeks

Now, with the information given we have to multiply the number of weeks by the cost per visit multiplied by 2 ( because marla swims twice a week) and add the quipment cost ($32.85) and the membership cost ($35).

Mathematically speaking:

$3.50 x 2 x 52 w + $32.85 + $35 =

$364 + $32.85 + $35 =$431.85

In conclusion, swimming will cost $431.85 for Marla (per year).

$431.85. I got this by multiplying the amount of weeks in a year (52) by two to get 104. I then multiplied that by 3.5 to get 364. I then added 32.85 and 35 to that to get $431.85

Coach Kelly bought 32 L of water to the football game, and she divied the water equally between 8 coolers how many milliliters of water did coach Kelly put in each cooler

Answers

ANSWER

Find out the how many milliliters of water did coach Kelly put in each cooler.

To proof

let us assume that the water put in the each cooler be x.

As given

Coach Kelly bought 32 L of water

she divied the water equally between 8 coolers

1 litre = 1000 miilitre

$x = (32* 1000)/(8)$

solving the above

x = 4000 millitre

therefore 4000 milliliters of water did coach Kelly put in each cooler.

Hence proved

I was walking to the store at the same time as my friend Angela. No matter what, She has always gotten there twice as fast as me. Half way to the store her friend picks her up on his scooter which was 10 times faster than me. She got there in 30 minutes. How long did it take for me to get there?

Answers

let's call your speed "a"

her walking speed is then "2a"

and her friend's scooter speed is 10 a

let's also call the distance you need to walk "d"

so the time (t)you need is:

d/t=a
t=d/a

and her time is:
t= $(d)/(2) /2a+ (d)/(2) /10a$
(half a distance with the speed of 2a and half a distance (d/2) with the distance of 10 a

now we count (we know that her time is 30 minutes)

30= $(d)/(4a)+(d)/(20a)$ //multiply by 20a

600a= $5d+d$
600a=6d/divide by 6
100a=d

Now, in order to calculate your time we need to calculate:

t=d/a

but we know how much is d now!
t= $(100a)/(a)$ =100

which means that you need 100 minutes, or 1 h 40 minutes!!!

Use the table below to answer the following question.2. Do the values in the table represent a linear function? If so, what is the function rule?
(1 point)
The values do not show a linear function.
Yes, the values show a linear function: y = x + 4.
Yes, the values show a linear function: y = 2x + 2.
Yes, the values show a linear function: y = 2x.
