Step-by-step explanation:
The number of total students is 18+12+10=40
So
1) 18:40 but simplified it will be 9:20
2) 10:40 but simplified it will be 1:4
3) 30:40 but simplified it will be 3:4
4) 30:10 but simplified it will be 3
5) 18:22 but simplified it will be 9:11
N.B simplified means dividing them by their common multiple. so the final answer for each is the number after it is simplified

Last week, Danielle spent x dollars on lunch, three times as much on transportation as she did on lunch, and $4 less on books than she did on transportation.
Write the expressions for the total amount Danielle spent last week on transportation and books.
If Danielle had $59 to spend last week, what is the greatest amount she could spend on lunch?
Danielle spent three times as much on transportation as she did on lunch, so we can call this 3x.
She spent $4 less than on books than she did on transportation -> 3x - 4
So, she spent x + 3x + 3x - 4 (simplified as 7x - 4).
Danielle had $59 to spend last week -> 7x - 4 = 59
Solve for x : (59+4)/7 = 9
So, she can spend at max $9 on lunch
Recheck : 9 + 27 + 27 - 4 = 63 - 4 = 59.

"How many
2/3
are in 3?"
Write a multiplication equation and a division equation.
Answer:
Change two-thirds to a decimal and then multiply the decimal and your number. To convert 2/3 to decimal, divide the numerator by the denominator: 2 / 3 = 0.66666 ... 7, which you can round to 0.67. For example, to find 2/3 of 21: 0.67 * 21 = 14.07.
A triangle has two angles that are 68 degrees and 78 degrees. What is the third angle
Answer:
36°
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180°.
Two of the angle measures are given already so all we need to do is to add up the measures.
Let x represent the missing angle:68 + 78 + x = 180
Add measures.144 + x = 180
Subtract 144 from both sides.x = 36°

of this weight is pears, and the rest is apples. How many kilograms of apples did she sell at the farmer's market?
Express your answer in fraction and decimal form.
Answer:
Total - 8.4 kilos
Pears; 2/5
Apples; Unknown
The rest of the 2/5 of pears is 3/5 apples.
3/5(apples) x 8.4(kilos)
0.6 x 8.4 = 5.04 or 5 4/100 which simplifies to 1/25

Answer:
3821.9 [cm³].
Step-by-step explanation:
1) the required volume can be calculated as:
V=V(prism)-V(cylinder);
2) V(prism)=32*12*11=4224 [cm³];
3) V(cylinder)=π*r²*32=3.1415*4*32≈402.1 [cm³];
4) finally, V=4224-402.1=3821.9 [cm³].
For more info see the picture in the attachment.
Answer:
3,822.08 cm2
Step-by-step explanation:
You would start off by finding the volume of the who post which is 4,224. You then would find the volume of the hole cut out which is 401.92. Then you would subtract 401.92 from 4,224 giving you 3,822.08.

Answer:
x = 1
Step-by-step explanation:
a^2 + b^2 = c^2
The hypotenuse (c) and a side length is already given, so:
x^2 + 12 = 13
x^2 = 1
Square root of 1 = 1
So, x = 1
You can check it by 1+12=13
Which model shows 1/2 times 1/3
Answer:
Where's the model?
Hai there!
First, let's use the KCF technique (my old math teacher taught me this!)
Keep the first fraction the same, in this case, 1/2
Change the sign from division to multiplication
Flip the second fraction, or 3/8, to get it's reciprocal, or 8/3.
The new equation should look like this:
1/2 * 8/3
Now multiply straight across like you normally would, like so:
1 * 8 = 8
2 * 3 = 6
