Tim is making 30 sundaes with mint, chocolate, and vanilla ice cream.
1/5
of the sundaes are mint ice cream and
1/2
of the remaining sundaes are chocolate. The rest will be vanilla. How many sundaes will be vanilla?
Answer:
12
Step-by-step explanation:
1/5 mint = 6
30 - 6 = 24
Half of 24 is 12
12 is chocolate
so 12 must be vanilla

Answer: Gina and Rhonda work for different real estate agencies. Gina earns a monthly salary of $5,000 plus a 6% commission on her sales. Rhonda earns a monthly salary of $6,500 plus a 4% commission on her sales. How much must each sell to earn the same amount in a month?
Step-by-step explanation:
$5,000 + 6% + $6,500 + 4% = 11500.1 or 11500
Libby can finish a paper in 2 hours. Ethan can finish the same paper in 4 hours. How
long will it take them to finish a paper if they work together?
Answer:
1.33333 hours
Step-by-step explanation:
Given :
Time taken by Libby = 2 hours
Time taken by Ethan = 4 hours
rate = 1 / time taken
Libby's rate = 1 /2
Ethan's rate = 1/4
Combined rate = Libby's rate + Ethan's rate
Combined rate = 1/2 + 1/4 = 3/4
Time taken = 1 / combined rate
Time taken = 1 / (3/4)
Time taken = 4 /3
Time taken = 1.33333 hours

Answer:
volume of hemisphere = 452.16 ft³
volume of cylinder = 2260.8 ft³
total volume = 2712.96 ft³
1/3 full = 904.32 ft³
Step-by-step explanation:
volume of hemisphere = 1/2(4/3)(3.14)(6³) = 452.16 ft³
volume of cylinder = (3.14)(6²)(20) = 2260.8 ft³
total volume = 452.16 + 2260.8 = 2712.96 ft³
1/3 full = 2712.96/3 = 904.32 ft³
What is the solution to this system of equations?
X+ 2y = 4
2x-2y = 5
0 (3.-52
0 (3.3
O no solution
infinitely many solutions
Answer:
3, 1/2
Step-by-step explanation:
x + 2y = 4
2x - 2y = 5
_______________ +
2x + x + 2y + (-2y) = 4 + 5
3x + 0 = 9
3x = 9
x = 9/3
x = 3
if you want to find the value of y, you just have to choose one of the equation. I will choose x + 2y = 4, even if you choose 2x - 2y = 5 the result remains same
x + 2y = 4
3 + 2y = 4
2y = 4 - 3
y = 1/2
x, y = 3, 1/2

The sheet of metal has dimensions 56 cm by 33 cm. It sis melted down
and recast into discs of the same thickness and radius 7 cm. How many
disces will be cast ?
Answer:
12
Step-by-step explanation:
To determine the number of discs, divide the area of the metal sheet by the area of the discs
The metal sheets are in the shape of a rectangle, thus the area of a rectangle would be used to determine the area of the sheet
Area of a rectangle = length x breadth
56 x 33 = 1848 cm^2
The disc is in the shape of a circle.
area of a circle = πr²
π = 3.14
r = radius
3.14 x 7² = 153.86 cm²
Number of discs = 1848 /153.86 = 12
"Solve for x" also show how to do it so I can do it myself and actually learn.
Answer:
9√2
Step-by-step explanation:
To do this, we need to use the Pythagoras' Theorem. Which is a^2+b^2=c^2
In this case, we need to solve for C. So, we do 9^2 (A) +9^2 (B), assuming a and b are the same. So we end up with 81+81=c^2. Now, we find the square root of 162. Around 13 or 9√2
Complete the statement. Round to the nearest hundredth if necessary.

Your class is planning a breakfast bake sale and you have been tasked to bake the donuts and bagels. The system below represents the total amount of flour, in pounds, needed to replicate a batch-of-six bagel recipe and a batch-of-twelve donut recipe. You will be replicating the donut recipe d number of times and the bagel recipe b number of times. 3d + 5b = 21 d + b = 5
Answer:
3 bagel recipe and 2 doughnut recipes are needed
Step-by-step explanation:
Given the expression
3d + 5b = 21 .. 1
d + b = 5 .... 2
We can use the expression to look for the amount of doughnut recipe and bagel recipe needed by solving the equations simultaneously
Multiply equation 1 by 1 and 2 by 3 to have;
3d + 5b = 21 .. 3
3d + 3b = 15 .... 4
Subtract 3 from 4
5b - 3b = 21 - 15
2b = 6
b = 6/2
b = 3
Substitute b = 3 into equation 2;
From 2,
d = b = 5
d + 3 = 5
d = 5 - 3
d = 2
Hence 3 bagel recipe and 2 doughnut recipes are needed

You put the names of all the students in your class in a paper bag. There are 14 boys and 20 girls. If you draw a name at random, what is P(boy’s name)?
Answer:
7/17
Step-by-step explanation:
you add the number of students which is 34. Then you take the number of boys and put it over 34 which would be 14/34. when you reduce it the answer will be 7/17.

Enter the correct answer in the box. Function g is the result of these transformations on the parent sine function: vertical stretch by a factor of 3 horizontal shift left units vertical shift down 4 units Substitute the values of A, C, and D to complete the equation modeling function g. g(x) = Asin(x + C) + D
Answer:
By substituting the values of A, C, and D the equation modelling the function is;
g(x) = 3·sin(x - π/2) - 4
Step-by-step explanation:
From the given information, we have;
The vertical stretch of the sine function = 3 × The parent function
∴ A = 3
Given that the horizontal shift left = π/2 units, (from an online source with similar question)
The vertical shift down = 4 units
The given function, g is g(x) = A·sin(x + C) + D
Where;
A = The amplitude = The maximum displacement from the rest or equilibrium position = 3
C = The horizontal shift = -π/2 (The negative sign is for the shifting to the left)
D = The vertical shift = -4 (The negative sign is for a shift in the downward direction)
Therefore, the equation modelling the function is;
g(x) = 3·sin(x - π/2) - 4
Answer:
g(x) = 3·sin(x + π/2) - 4
Step-by-step explanation:
shifted left, it will be positive inside the parentheses

Given the figure below, find the values of x and z.
Answer: Z = 83
X = 7
Step-by-step explanation:
Z = 83 because the opposite side is also 83 and they are the same angle. X = 7 because the whole thing equals 360 and 83 +83 = 166 and 360 - 166 = 194 and 194 divided by 2 equals 97 and 15 x 7 - 8 = 97 and the other side is also the same because the angles are the same
