the ratio of girls to boys in an astronomy club was 3:2. there were 30 girls. how many total members were there in the club
Answer:
Explanation: the ratio 2:4 can be reduced to 1:2, where the number of girls corresponds to the 1 and the number of boys corresponds to the 2. If there are 14 girls, then there must be 28 boys (14 x 2 = 28). Now to get the total number we need to add the total number of boys and girls together. So 14 + 28 = 42

By rounding each of 9.85, 3.875 and 6.3 to the nearest whole number work out an estimate for the answer to 9.85^3 / 3.875 + 6.3^2
Answer:
286.
Step-by-step explanation:
9.85^3 /3.875 + 6.3^2
= 10^3/ 4 + 6^2
= 1000/4 + 36
=250 + 36
=286.

Andre types 208 words in 4 minutes. Noah typed 342 words in 6 minutes
A) Who typed faster
B) How many words can andre type in 10 minutes
C)Would you find the unit rate of words per minute or the unit rate of minutes per word to
figure out how long it would take Noah to write 1710 words? Why? (You do not need to
solve, just choose and explain why).
Answer:
Noah types faster because he can type more words per minute.
Step-by-step explanation:
For Andre you would divide 208 words by 4 minutes getting 52 words per minute. Then, for Noah divide 342 words by 6 minutes getting 57 words per minute.

Sand costs three times as much as rocks per pound. If sand is $9.60 per pound, how much are rocks per pound?
Answer:
Rock costs $3.20 per pound.
Step-by-step explanation:
Because sand costs three times as much as rocks per pound, you can determine the cost of rocks per pound by dividing the cost of sand per pound by three:
[tex]\frac{9.60}{3}[/tex] [tex]= 3.20[/tex]
Zee wants to make 2 liters of a special drink for a party. She squeezed the eight lemons she had and got 0.375 liters of lemon juice. She had 0.35 liters of cranberry juice, and 1.2 liters of water.How much of the special drink can she make? How much more or less than 2 liter will she have
Answer:
1. 1.925 Liters
2. 0.075 Liters less than the 2 Liter of special drink
Step-by-step explanation:
Step 1
Quantity of lemon juice = 0.375 Liters
Quantity of cranberry juice = 0.35 liters
Quantityof water = 1.2liters
Total Quantity of Special drink = 0.375 L+ 0.35L + 1.2 L= 1.925 Liters
Step 2
But since she wanted to make 2 Liters of the special drink she will have
2 Lter - 1.925L= 0.075Liters less than the initial 2 Liter of special drink planned.
Answer:
a. 1.925 litres
b. 0.075 litres less
Step-by-step explanation:
a. How much of the special drink can she make?
To find out the quantity of juice produced, add the component juice quantities and the water:
= 0.375 + 0.35 + 1.2
= 1.925 litres
b. How much more or less than 2 litres will she have?
= 2 - 1.925
= 0.075 litres less

My wife baked cookies this year. 40% of the cookies she baked were chocolate chip. If she baked 36 chocolate chip cookies, how many total cookies did she bake
Answer:
She baked 90 cookies.
Step-by-step explanation:
From the information given you know that 36 cookies represent 40% of the cookies that were baked. With this information, you can use a rule of three to find the total mount of cookies that she baked:
36 cookies → 40%
x ← 100%
x=(36*100)/40=90
According to this, the answer is that she baked 90 cookies.

Mrs. Pena is buying 3 kinds of sandwiches for a family reunion. She buys x egg salad sandwiches at $3.10 each. She buys
y corned beef sandwiches at $3.35 each. Finally, she buys z cheese sandwiches at $2.85 each. Mrs. Pena spent a total of
$148.55 on the sandwiches. Which equation could be used to represent the situation?
A 3.10x + 3.35y + 2.85z = 148.55
00
(3.10 + 3.35 + 2.85)xyz = 148.55
(x + y + 2)(3.10 + 3.35 + 2.85) = 148.55
D
x + y + z = 148.55
a concert is attended by 2500 people. if 47% are adult females
and 32% are
adult males how many children attended?
Answer:
525 children attended the concert.
Step-by-step explanation:
Given that:
Total number of people who attended concert = 2500
Adult females = 47%
Adult males = 32%
Percent of children = (100-47-32)% = 21%
Number of children = 21% of people who attended
Number of children = [tex]\frac{21}{100}*2500[/tex]
Number of children = 0.21*2500 = 525
Hence,
525 children attended the concert.

Answer:
D. $103800Step-by-step explanation:
Initial value of house:
$184000Yearly increase rate of value:
3.5%Time
13 yearsSince the increase is concerning the current price it would be exponential growth.
The function would be:
V(t) = 184000*(1 + 3.5/100)^t, where V is the value after t yearsFor t= 13 we get:
V(13) = 184000*(1.035)^13 = 287800Profit made would be:
287800 - 184000 = 103800Correct option is D.
Answer:
Cost of Tammy's house =$184000
Rate of interest = 3.5% per annum
After 13years price will be
[tex]P(t) = 184000 {(1 + \frac{3.5}{100}) }^{t} \\ P(t) = 184000 {(1 + 0.035)}^{t} \\ P(13) = 18400 {(1.035)}^{13} \\ P(13) =\$ 287768[/tex]
Total profit= $(287767-184000)= $103768
