After making a deposit,puja had $264 in her savings account.She noticed that if she noticed that if she added $26 to the amount originally in the account and doubled the sum,she would get the new amount.How much did she originally have in the account.
Answer:
Let the original deposit be
x
Add $26 to original deposit
→
x
+
26
And doubled the sum
→
2
(
x

The formula of volume of the cube is given by: Volume = a3, where a is the length of its sides or edges.
Given:
volume of cube= 64 cm³
Now, Volume of cube = 64
a*a*a= 64
a³ = 64
a= ∛64

A test is worth 50 points. Multiple-choice questions are worth 1 point, and
short-answer questions are worth 3 points. If the test has 20 questions, how
many multiple-choice questions are there?
A. m + s = 50
B. m + 2s = 20
C. m.s= 20
D. m + s = 20
Answer:
d) m + s = 20
m = 5
Step-by-step explanation:
m + 3s = 50
m + s = 20
m + 3(20-m) = 50
m + 60 - 3m = 50
60 - 2m = 50
60 = 50 + 2m
60 - 50 = 2m
10 = 2m
5 = m
With the equation 3z+3=2z+6
Answer:
z = -3
Step-by-step explanation:
Simplifying
3z + -3 = 2z + -6
Reorder the terms:
-3 + 3z = 2z + -6
Reorder the terms:
-3 + 3z = -6 + 2z
Solving
-3 + 3z = -6 + 2z
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '-2z' to each side of the equation.
-3 + 3z + -2z = -6 + 2z + -2z
Combine like terms: 3z + -2z = 1z
-3 + 1z = -6 + 2z + -2z
Combine like terms: 2z + -2z = 0
-3 + 1z = -6 + 0
-3 + 1z = -6
Add '3' to each side of the equation.
-3 + 3 + 1z = -6 + 3
Combine like terms: -3 + 3 = 0
0 + 1z = -6 + 3
1z = -6 + 3
Combine like terms: -6 + 3 = -3
1z = -3
Divide each side by '1'.
z = -3
Simplifying
z = -3
Answer:
=3z+3=2z+6
=3z-2z=6-3
=z=3

For every 15 students who run track, there are 7 students who play baseball. There are 112 more students who run track than play baseball. How many students run track? How many students play baseball? Select your answers from the drop-down lists.
Answer:
210 students run track and 98 students play baseball
Step-by-step explanation:
For every 15 students who run track there are 7 students who play baseball
There are 112 more students who run track than play baseball
Let y represent the various groups of students
15 × y= 15y
7 × y= 7y
15y - 7y = 112
8y = 112
Divide both side by the coefficient of y which is 8
8y/8 = 112/8
y= 14
Therefore the number of students that run track is
= 15 × 14
= 210
The number of student that play baseball is
= 7 × 14
= 98
Hence 210 students run track and 98 students play baseball

True or False? In reference to different sampling methods, systematic sampling includes the steps: list the members of the population; use simple random sampling to select a starting point in the population; let k = (number of individuals in the population)/(number of individuals needed in the sample); choose every kth individual in the list starting with the one that was randomly selected.
Answer:
True
Step-by-step explanation:
In the simple random sampling every individual in the population has an equal chance to be selected in the sample. Systematic sampling is a probability sampling in which selection of elements is made from order frame. These samples are selected based on intervals of the population.
Which expression is equivalent to 2(a+3) when a=3?
O 2(3)
05(3)
O 2(3)+3
O 2(3)+6
Answer:
The answer is 2(3)+6
Step-by-step explanation:
The perenthesis means multiplication so you would first do 2 times three which is 6 and then 6+6=12 and the first expresion is 2(a+3) a=3 to solve that you would do whats in the perenthesis 3+3 which equals 6 and then the 6 in the perenthesis means mulitplication. so then you would do 2 times 6 and get 12. so the 3rd one is the answer.

11 AM?
Answer:
4 degrees farenheight
Step-by-step explanation:
Answer:
4 degrees
Step-by-step explanation:
7am to 11am is 4 hours.
So now multiply 4 hours*4* F = 16
So the temperature decreased 16 degrees.
20-16=4
It was 4 degrees at 11 am.
A music store is receiving a shipment of Ipads. Each box comes with 12 white, 12 black and 24 grey
Ipads. They already have 23 white, 16 black and 22 grey Ipads. If the store is receiving 5 boxes, how
many of each color Ipad will they have?
Answer:
142 Grey, 83 white, 76 black
Step-by-step explanation:
If you were to take 5 boxes and put 24,12,12 in each, then multiply each number by 5 you wpuld get 120 Grey, 60 white and 76 black. Then you would add what they already have 120 Grey + 22 Grey is 142 grey, 60 white + 23 white is 83 white, and 60 black + 16 black is 76 black.
given g(x)=0.5x^2-5x+3.5, find g (4a)
Answer:
g(4a) = 8a^2 -20a +3.5
Step-by-step explanation:
Put 4a where x is and simplify.
g(x) = 0.5x^2 -5x +3.5
g(4a) = 0.5(4a)^2 -5(4a) +3.5
= 0.5(16a^2) -20a +3.5
g(4a) = 8a^2 -20a +3.5

If 5/x = 15/x+20, what is the value of x/5?
Answer:
c) 2
Step-by-step explanation:
here you can use cross multiplication. that's where you turn the fraction into an equation. ( there's videos about it, I'm not very good at explaining )
so you can turn
[tex]\frac{5}{x} = \frac{15}{x + 20}[/tex]
into
5(x + 20) = 15x
5x + 100 = 15x
subtract 5x from both sides
100 = 10x
x = 10.
the value of x/5 would be 2, since 10/5 is 2.
Since x/5 is the reciprocal of 5/x, we know that we can flip the fraction on the right hand side will be flipped.
Thus, x/5 = (x + 20)/15
Now we cross multiply, 15x = 5(x + 20)
Simplify: 15x = 5x + 100
Subtract 5x from each side: 10x = 100
Divide 10: x = 10
Now plug 10 back into the right hand side: (10 + 20)/15
So, the answer is 2.
