Answer:
4 : 7
Step-by-step explanation:
Given 2 similar figures the if the ratio of perimeters = a : b
The the ratio of areas = a² : b²
Here
ratio of areas = 16 : 49 , then
ratio of perimeters = [tex]\sqrt{16}[/tex] : [tex]\sqrt{49}[/tex] = 4 : 7

question and diagram is circled in picture
Arc PR = ___ degrees
Please help me! I'll give brainliest!
Answer:
16. Angle 2 is 30° and angles 1 & 3 are 150°
17. Equilateral (all sides are equal)
18. A, B, D
19. A, B. (8 angles and all sides are congruent)
20. False.
Step-by-step explanation:
angle 2 is a corresponding (ish) angle to the one marked 30°, so they are the same. and then the other angle is supplementary to the 30° one, therefore they must add up to 180 degrees. 180-30= 150 so that is angle 1 and 3.
Answer:
question 1 - angle 1 and 2 the answer is 150 and angle 3 is 30
question 2 - the triangle is an equilateral
Question 3 - A,B,D
question 4 - A,B
Step-by-step explanation:

Answer:
x = 50°
Step-by-step explanation:
The triangle has 3 congruent sides and is therefore equilateral.
The 3 angles are then congruent, each 60°
The left angle in the quadrilateral is adjacent to 60° of the triangle
180° - 60° = 120° ← angle inside quadrilateral
The sum of the interior angles of a quadrilateral = 360°
Subtract the sum of the angles from 360° for x
x = 360° - (120 + 90 + 100)° = 360° - 310° = 50°
Quadrilaterals A and B are similar.
Find the values of the sides marked
x
,
y
:
Answer:
x = 17.5
y = 5
Step-by-step explanation:
Similar means that corresponding angles (same colors in this case) are the same. Rotate the 2nd figure on the right in your mind until the angle label colors fit the 1st figure, just so you can tell what's what. Then you can create ratios with corresponding sides that include only one of the unknowns. So 1st we use
x/7 = 15/6
x = 15/6 * 7
x = 17.5
and
y/12.5 = 6/15
y = 6/15 * 12.5
y = 5

Trey bought 3 and 3 fourths pounds of apples from the grocery store. Corinne bought 1 and 1 third pounds of grapes from the grocery store. How many more pounds of fruit did Trey buy
Answer: 2 5/12
Step-by-step explanation:
Trey bought 3¾ pounds of apples from the grocery store. Corinne bought 1⅓ pounds of grapes from the grocery store.
To know how many more pounds of fruit that Trey bought, we have to find the difference between the value given above and this will be:
= 3¾ - 1⅓
= 3 9/12 - 1 4/12
= 2 5/12
Trey bought 2 5/12 pounds more.
This is just the first pic of the problem I’m posting the second one right after this

Andrea uses 9.8 pints of white paint and blue paint to paint her bedroom walls. 1 4 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answer:
7.35
Step-by-step explanation:
Andrea uses 9.8 pints of white and blue paints to paint her bedroom walls
1/4 of this amount is white paint
= 1/4 × 9.8
= 0.25×9.8
= 2.45
Therefore the amount of blue paint can be calculated as follows
9.8-2.45
= 7.35
Hence 7.35 are blue paint
3 security guards below whistle at interval of 50 minutes, 60 minutes and 100 minutes if they blow together at 1:00am,at what time will they blow together again
Answer:
They will blow together again at 6:00 am
Step-by-step explanation:
Guard 1 whistles every 50 minutes.
Guard 2 whistles every 60 minutes.
Guard 1 whistles every 100 minutes.
Assuming that at the beginning they whistle together, the next time that they will whistle together is after the smallest common multiple of 50, 60, and 100.
Because one of the numbers is 100, it only has multiples like:
100*2 = 200
100*3 = 300
100*4 = 400
etc...
So we need to find a common multiple of 50 and 60 that is also a multiple of 100.
For example, the multiples of 50 that are also multiples of 100 are:
50*2 = 100
50*4 = 200
50*6 = 300
And the multiples of 60 that are also multiples of 100 are:
60*5 = 300
(this is the only one)
Then we can see that a common multiple of 50, 60 and 100 is 300.
Then they will whistle together 300 minutes after the first common whistle.
We know that they blow together at 1:00 am
300 minutes after it is:
First, we need to write 300 minutes in hours.
We know that one hour has 60 minutes.
then 300 minutes = (300 minutes/60 minutes) hours = 5 hours.
300 minutes after 1:00 am is the same as 5 hours after 1:00 am
And 5 hours after 1:00 am is 6:00 am
They will blow together again at 6:00 am

Part A: Mike wants to join a gym. He has to pay an initiation fee of $16 and equal monthly payments for the year. The most he wants to pay is $580 for the year for his gym membership. a.) Write an inequality that you can use to determine the most he would want to spend for his monthly payments.
Part B: Now use your inequality from 15a to determine how much Mike’s monthly gym payment can be if the most he wants to pay is $580 for the year for his gym membership..
Answer:
Part A: [tex]12x+16\leq 580[/tex]
Part B: $47 per month
Step-by-step explanation:
Part A: 12 months in a year. Pays x amount of $ per year, with an additional $16 initiation fee. He wants to spend less than $580 total a year. Thus, [tex]12x+16\leq 580[/tex].
Part B: Solve the inequality for x.
$580 - $16 = $564
x = $564/12 = $47

The January record high temperature in Austin, Texas is 92 degrees. The January record low temperature is -1 degree. What is the difference between the record high and low temperatures?
Answer:
93
Step-by-step explanation:
The forecast high is the highest temperature expected to occur that day, which in most cases is in the afternoon. When referring to the recorded high/low from a previous day, the high and low-temperature values are the actual temperature extremes that were recorded during that 24-hour calendar day.
Given: Texas is 92 degrees. January's record low temperature is -1 degrees.
To find: What is the difference between the record high and low-temperatures?
Solution: Subtract -1 from 92, 92 - (-1) = 93
The minimum charge for first 175 of telephone calls
is Rs. 300. If the charge of each additional call is Rs.
3.50 , how much will be charge for 389 telephones
calls?
Answer:
Rs. 1,049
Step-by-step explanation:
Charge for 175 of telephone calls
= Rs. 300
Additional charge per call = Rs.
3.50
how much will be charge for 389 telephones calls?
389 telephones calls - 175 telephones calls = 214 telephones calls
Charge for 389 telephones calls = charge of 175 telephone call + (charge of 389 telephones calls - 175 telephones calls)
= Rs. 300 + charge of 214 telephones calls
= Rs. 300 + 214(Rs. 3.50)
= Rs 300 + Rs. 749
= Rs. 1,049

Answer:
$8.88
Step-by-step explanation:
24yds needed = 864 inches
864/150 = 5.76 so he'll need 6 spools
6x 1.48 = $8.88
Answer:
$7.40
Step-by-step explanation:
First, take 78% of 24, which is 18.72. So 18.72 yards of ribbon will be blue. Then, convert the number of yards to inches. You can multiply it by 3 to get the number of feet and then that number by 12 to get the number of inches. So you'll have 673.92. Next, figure out how many spools Jordan needs. Divide 673.92 by 150. You get around 4.4, but since you can't buy 0.4 spools, Jordan will need to buy 5 of them.
So multiply 1.48 dollars by 5 spools and you'll get $7.40. Which is how much Jordan spent on blue ribbon.
