There are 40 students in Joan’s class. She plans to invite them to her birthday party. She asked them to suggest a theme for her party. Three of every eight students suggested a rainbow-themed party. How many students suggested a rainbow-themed party? How many did not?
Answer:
15 people suggested, 25 did not
Step-by-step explanation:
3 of every 8 so 3:8
There is 40 students in total, so 40/8=5. 5*3=15
15 people suggested, 25 did not
Answer:
15 students suggested a rainbow-themed party.
25 students did not suggest a rainbow-themed party.
Step-by-step explanation:
40 students
3 out of every 8 students suggested rainbow them
40/8 = 5
5 groups = 40 students
1 group = 8 students
3 × 5 (amount of groups) = 15
15 students suggested a rainbow-themed party.
40 - 15 = 25
25 students did not suggest a rainbow-themed party.

Angie bikes for 20 minutes burning 150 calories. How many minutes will it take to burn 525 calories?
Answer:
70 minutes OR 1 hour and 10 minutes (it's the same thing)
Step-by-step explanation:
So this can be modeled by the equation 20/150=x/525
so solving for x, you have to say whats the most times that 150 will go into 525 without going over
the answer is 3
so 150x3=450 and 525-450=75
75 is one half of 150 so it would be 3.5
multiply 20 by 3.5 and you get 70 or 1 hour and 10 minutes since an hour is 60 minutes

Sara has $25,000 to buy cell phones and chargers for her employees. She buys 38 phones for $640 each. Each charger costs $18. How much money will be left after she buys as many chargers as possible?
I NEED the shown work as well please
Answer:
-4
Step-by-step explanation:
if you multiply 38 x 640 it will be 24320, and if you multiply 18 x 38 it will be 684. add 24320 and 684 it will be 25004 which means she has -4 dollars i believe
Answer:$14
Step-by-step explanation:
640x38 = 24,320
25,000-24,320 = 680
680/18 = 37.7777 and on
so you would make that 37 chargers she can buy with the remaining money.
37x18 = 666 and 680-666=14

Convert 150 pounds to kilograms. (1 pound = 0.454 kilogram)
68.1 kilograms
6.81 kilograms
681 kilograms
0.00681 kilogram
At the conversion rate, 1 pound = 0.454 kilograms, 150 pound is 68.1 kilograms.
What is multiplication?The mathematical operation of multiplication is arithmetic. Additionally, it involves repeating the same forms of statements.
Given, conversion rate
1 pound = 0.454 kilograms
To covert the n pounds:
n x 1 pound = n x 0.454 kilograms
Here, we have n = 150
150 x 1 pound = 150 x 0.454 kilograms
150 pounds = 150 x 0.454 kilograms
150 pounds = 68.1 kilograms
Therefore, 150 pounds = 68.1 kilograms.

An architect designs two similar triangular patios. The first patio has angle measures of (x + 10)°, (y + 5)°, and 40°. The second patio has angle measures of (x – 10)°, 60°, and 80°. Find the values of x and y.
HELPPPP PRETTY PLEASEEE ASAP
Answer: x=230 and y=75
Step-by-step explanation: A triangle is worth 360 degrees, which means when you add up all the angles it equals 360 degrees. So
Second patio:
(x-10),60+80 = 360
x-10+140 =360-140
x-10=220+10
x=230
First patio:
(x+10)+(y+5)+40 = 360
x+y+55=360
x+y=360-55
x+y=305- x(230) =75
y=75
Answer: x = 50, y = 75
The sum of angles of a triangle is equal to 180°
according to the question, (x+10) + (y+5) + 40 = 180 -- eq(1)
(x-10) + 60 + 80 = 180 -- eq(2)
(x - 10) + 140 = 180
x - 10 +140 = 180
x + 130 = 180 , x = 180 - 130
x = 50
put x value in eq(1)
50+10 + (y+5) + 40 = 180
60+(y+5)+40 = 180
y+5 +100 = 180
y + 105 = 180
y = 180 - 105
y = 75
So, x = 50 and y = 75.
