Becca made 960 cookies to sell. She wants to package the cookies in the the boxes of 16 . Her goal is to make $630 from selling her cookies . If each box of cookies is priced the same , how much should Becca charge for each box ?
Step-by-step explanation:
Total cookies = 960
Each box has 16 cookies
Her goal is $630
First, you want to find out how many boxes she made
960÷ 16 = 60
She made 60 boxes
Now you want to find the price for each box
630 ÷ 60 = 10.5
She should charge $10.50 for each box
I hope this helps!!!

Bo Karah can run a race in 4 hours 33 minutes if he runs at 7 m/s. How long will it take in hours and minutes if
he runs at 11 m/s? Give your answer to the nearest minute.
Answer:
7 hours and 9 minutes
Step-by-step explanation:
4 hours and 33 minutes is 273 minutes
7 m/s —> 273 minutes
11 m/s —> M
Criss cross to get M
11x273= 7M
3003=7M
M=429 minutes
==> 429 minutes is 7 hours and 9 minutes
Xavier is half as old as Jessica. The sum of their ages is 63. How old is Jessica? (
Answer:
31.5
Step-by-step explanation:
Answer:
let their age be x and y
x=y.......1st equation

now,
product of their age
x+y=63
y +y=63 (putting the value of x=y/2)

Sum of the radius of the base and height of a cylinder is 21 cm and the curved surface area of the cylinder is 616 sq.cm,find the total surface area of the cylinder.
PLEASE HELP ME AS FAST AS POSSIBLE
Step-by-step explanation:
lets radius be r and height be h,
r+h=21 -----(1)
curved surface area
2×pi×r×h=616 -----(2)
use simultaneous eqn to solve for r and h.
total surface area of cylinder= 2×pi×r×h + 2×pi×r²
= ans if im not wrong

Answer:
Choice c. [tex]\sqrt{12}[/tex]
Step-by-step explanation:
Vectors
Suppose we have a vector v defined as
[tex]\vec v=a\mathvf{i}+b\mathvf{j}[/tex]
The magnitude of the vector is:
[tex]\mid\mid\vec v\mid\mid=\sqrt{a^2+b^2}[/tex]
On the other hand, the dot product of the vector by itself is:
[tex]\vec v\cdot\vec v=a*a+b*b=a^2+b^2[/tex]
Note the relation between these two operations is:
[tex]\mid\mid\vec v\mid\mid=\sqrt{\vec v\cdot\vec v}[/tex]
Since we are given:
[tex]\vec v\cdot\vec v=12[/tex], then:
[tex]\mid\mid\vec v\mid\mid=\sqrt{12}[/tex]
Choice c) [tex]\sqrt{12}[/tex]

What is the approximate circumference of a circle that has a radius of 10 centimeters? (Use 3.14 for ). C=__ cm
Answer:
C = 62.8 cm
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightGeometry
Circumference Formula: C = 2πrStep-by-step explanation:
Step 1: Define
r = 10 cm
Step 2: Find C
Substitute [CF]: C = 2π(10 cm)Multiply: C = 20π cmMultiply: C = 62.8 cmAnswer:
62.8
Step-by-step explanation:
Radius is 10, so the diameter is 20 (10x2)
20 x 3.14(pi)= 62.8
In a survey of school students, 64 had taken mathematics course, 94 had taken chemistry course, 58 had taken physics course, 28 had taken mathematics and physics, 26 had taken mathematics and chemistry, 22 had taken chemistry and physics course, and 14 had taken all the three courses. Find how many had taken one course only by using Venn diagram.
Answer:
106
Step-by-step explanation:
From the information given :
Let:
Mathematics = M
Physics = P
Chemistry = C
n(M) = 64 ; n(C) = 94 ; n(P) = 58
All three (n(MnCnP) = 14

Write the following inequality in slope-intercept form: 4x – 2y < 10
Answer:
y>2x-5
Step-by-step explanation:
-2y+4x<10
-2y<10-4x
divide by -2 to isolate the y
y>-5+2x
Since we are dividing by a negative the sign flips.
Our final answer is y>2x-5
4. A line with a slope of -2 passes
through the point (3,-1). Which of
the following is the equation of
the line?
O y = 3x – 2
O y= -4x – 2
O y = -2x + 5
O y=-2x + 1

Darron is taking college classes while in high school. The classes cost $200 plus $35 for every credit hour. y = total cost of classes x = credit hours taken Which equation matches this linear function?
Answer:
y = 35x+200
Step-by-step explanation:
The $200 is a constant, and the $35 PER credit hour makes it dependent on x.

you roll a single die numbered from 1 to 6 twice. what is the probability of rolling a 6 the first time and an odd number second
Answer:
1/12
Step-by-step explanation:
Since the two rolls are independent, then the chance of getting a 6 in the first and an odd number in the second is obtained by multiplying the two probabilities.
1/6 is the probability of rolling 6, 1/2 is the probability of rolling an odd number
1/6 times 1/2 is 1/12
What is the y-intercept of a line that has a slope of —3 and passes through point (0, -7)?
_7
-3
0
4
Answer:
-7
Step-by-step explanation:
well, y-intercept is value of y when x = 0.
from the problem, we already have the answer, it is -7
but more detailed way is
m = -3
[tex] \frac{y - ( - 7)}{x - 0} = - 3 \\ y - ( - 7) = - 3x \\ y = - 3x - 7 \\ [/tex]
y-intercept is value of y when x = 0
[tex]y = - 3(0) - 7 \\ y = - 7[/tex]
(2 to the power -1 ÷ 5 to the power- 1)2 × -5/8 to the power -1
Answer:
-8
Step-by-step explanation
2 to the power of -1 = 0.5
5 to the power of -1 = 0.2
0.5/0.2 = 2.5
So,
(2.5)2 x -5/8 to the power of -1
-5/8 = -0.625
-0.625 to the power of -1 = -1.6
So,
(2.5)2 x -0.625
5 x -0.625
= -8
Answer:
-8
Step-by-step explanation:
(2^-1 ÷ 5^-1) = 5/2
(5/2) x 2 = 10/2 or 5
-5/8 ^-1 = - 8/5
5 x - 8/5 = -40/5 or -8
