Answer:
$168
Step-by-step explanation:
Divide $56 by $2
$56 ÷ $2 = 28
Thus $2 was donated 28 times
He donated $2 every time $6 was spent, then
money spent = 28 × $6 = $168
Answer:
$168
Step-by-step explanation:
We have the following ratio
Spent at shop : donated to charity
6:2
we know that
x:56
To solve this we just mulitply 6 by 28 (28 because this is what we mulitplied the two in our original ratio to reach 56)
6*28=168
A stadium has 8,436 seats that are divided into 12 different sections. Each section has the same number of seats.
How many seats are in each of the 12 sections? please show the work
Answer:
703
Step-by-step explanation:
You divide the 8436 by 12.
1. You can't divide the 8 by 12 so skip that
2. You can divide 84 by 12 so you get 7
3. Bring down the 3 (you have 0 as a remainder). You can't divide that so put a 0
4. Bring down the 6 and divide that (36) and you get 3
5. Your final answer would be 703.

Consider the following vectors: y = (2,4), v = (-1, -1), and w = (7.-2).
What is the vector for 3u + v- 2w in component form?
(20,15)
(10,7)
(-6,1)
(-9.15)
Answer:
(-9.15)
Step-by-step explanation:
We are given these following vectors:
u = (2,4), v = (-1,-1), w = (7,-2)
What is the vector for 3u + v- 2w in component form?
3u + v - 2w = 3(2,4) + (-1,-1) - 2(7,-2) = (6,12) + (-1,-1) + (-14,4) = (6 - 1 - 14, 12 - 1 + 4) = (-9, 15)
The answer is (-9,15).

A secret agent being a mathematician, transmitted an important 2-digit locker number in
the following manner: “The difference in the digits is four. The sum of the number and the number formed by reversing the digits is 132.” Find the locker number.
Answer:
48
Step-by-step explanation:
Since there are only a few possibilities, I was able to guess and check:
15+51=66 and 66 is not 132
26+62=88 and 88 is not 132
37+73=110 and 110 is not 132
48+84=132 and 132 is 132.

Explain what the diameter of a circle is. If you had the diameter of a circle, how could you solve for the circumference?
The diameter can be thought of as the width of the circle, more or less. More accurately, it's the distance from one point on a circle, through the center, to a point on the opposite side.
If we had a circle at point A, and some point on the edge of the circle point B, then line AB will form a third point C. Point C is on line AB and on the circle. Segment BC is a diameter.
We can measure the diameter with a straight line ruler, but we cannot do the same with the perimeter of the circle. The circumference is just a fancy name for "perimeter". Specifically, it only applies to circles. The way I remember it is that "circle" has "circ" in it, and so does "circumference". Furthermore, we can erase some letters of "circumference" to end up with "fence", which would go along an outer perimeter in a lot of cases. Overall, "circumference" makes me think of "circle fence".
How can we find the perimeter of a circle? Well we could use a cloth ruler to wrap around the edge of the circle. We'd have to make sure that none of the bendable ruler is out of place. So things could get tricky.
To find the circumference with a formula, we'll use this one here
C = pi*d
where pi = 3.14 approximately and d is the diameter
----------------------
For example, let's say the diameter is d = 10 feet. That would lead to a circle perimeter of....
C = pi*d
C = 3.14*10
C = 31.4
The circumference is approximate because pi = 3.14 is approximate. The units for the circumference in this case are in feet, so the distance around this particular circle is about 31.4 feet.
10. If ABCD is a kite, DB=48 in. and CE=7 in. find DC. *
49 in.
23 in.
25 in.
47 in.
Answer:
25 in.
Step-by-step explanation:
DEC is a right triangle. <DEC is a right angle.
(DE)² + (EC)² = (DC)²
DE = ½DB = ½(48 in.) = 24 in.
(24 in.)² + (7 in.)² = (DC)²
576 in.² + 49 in.² = (DC)²
(DC)² = 625 in.²
DC = 25 in.
The Statistical Abstract of the United States (109th edition) reported that the mean age of all U.S. registered merchant vessels is 23.6 years. Records for 38 randomly selected U.S. registered grain cargo ships showed that the mean age was 26.7 years with a standard deviation of 5.2 years. Is this type of ship older than the national average of all merchant vessels
Answer:
Yes, we can conclude that the ship is older than the national average
Step-by-step explanation:
Population mean, μ = 23.6
Sample mean, xbar = 26.7
Sample size, n = 38
H0 : μ = 23.6
H0 : μ > 23.6
The test statistic :
(xbar - μ) ÷ (σ/√(n))
(26.7 - 23.6) ÷ (5.2/√(38))
3.1 / 0.8435513
Test statistic = 3.675
Decision region :
Reject H0 ; if |Tstatistic| > |Tcritical|
Since we are given the sample standard deviation ; we use the T test distribution
df = 38 - 1 = 37
Tcritical at df = 37 ; α = 0.05 ; rigth tailed :
Tcritical(0.05, 37) = 1.687
3.675 > 1.687 ; Hence, we reject H0 and conclude that there is enough evidence that this type of shop is older than the national average.

What is the relationship between how Jews were portrayed to the public and their persecution during the holocaust?
Hint: Find how they were portrayed to the public by Hitler and then follow that up with How were they persecuted during the Holocaust?
Answer:
Step-by-step explanation:
This is actually in the wrong place. It should probably be in English or History, but I'll answer it anyway.
You need to start by seeing the way they were portrayed in cartoons, in writing (mainly newspapers), on the radio, in speeches and on the streets. Start with the Bible. The Old Testament was about the law mostly and behavior as much as anything. The people who lived and were governed by the OT generally were very pious unless they were rebellious sinners.
The New Testament is a slightly different matter. In most of Europe the peasantry thought the Jews were Christ Killers. That thought was dominent throughout the Middle Ages. It isn't true. Jesus was a Jew, so were the disciples, so were the huge crowds that followed Him to at least hear what he had to say.
It was only the ruling classes (The Pharisees, the Sadducees, and the scribes and teachers), that were not fond of Jesus. But that fact was not emphasized. Out of that picture and the displacement of the Jews after the Temple was destroyed, grew the caricatures of what the Jews were.
Anti Semitism was quite common in Europe. Most people fell for the propaganda that said the Jews were the spawn of the Devil. It became easy to kill those that were felt to be evil.
I urge you to start your own study of what happened. Start with the Inquisition.

Answer:
See below for answers and explanations
Step-by-step explanation:
1) Substitute d=100 into the equation and solve for s:
s=sqrt(9.81d)
s=sqrt(9.81(100))
s=sqrt(981)
s≈31.32
Therefore, the speed of the wave will be about 31.3 m/s
2) Substitute d=1000 into the equation and solve for s:
s=sqrt(9.81d)
s=sqrt(9.81(1000))
s=sqrt(9810)
s≈99.05
Therefore, the speed of the wave will be about 99 m/s
How much interest is to be paid at 1500 principal, 7% compounded annually, and for 3 years
Answer:
I = 337.56
Step-by-step explanation:
Given that,
Principal, P = 1500
Rate, R = 7%
Time, t = 3 years
We need to find the interest if it is compounded annually. We know that, the amount is given by :
[tex]A=P(1+\dfrac{r}{100})^n[/tex]
Put all the values,
[tex]A=1500\times (1+\dfrac{7}{100})^3\\\\A=1837.56[/tex]
We know that,
Interest = Amount - Principal
I = 1837.56 - 1500
I = 337.56
Hence, the interest is equal to 337.56.

Look at the angles and sides that are marked, and their relationships to each other. Shared sides are congruent to themselves. Vertical angles are congruent. The possible congruence theorems are ...
SSS SAS AAS ASA (and HL for right triangles--not applicable here)
__
1. two marked sides and the vertical angle between are congruent. The triangles are congruent by the SAS theorem.
2. only one side and angle are marked. Insufficient information. Not congruent.
3. two marked sides and the shared side are congruent. The triangles are congruent by the SSS theorem.
4. the vertical angles, the marked angles, and the marked sides are congruent. The triangles are congruent by the AAS theorem.
