The price of oil decreased from $52 per barrel to $48 per barrel. What is the percentage decrease in the price of oil? Round your answer to the nearest tenth of a percent.
Answer:
7.7%
Step-by-step explanation:
Given that,
The price of oil decreased from $52 per barrel to $48 per barrel.
We need to find the percentage decrease in the price of oil. It can be calculated as follows :
[tex]\%=\dfrac{52-48}{52}\times 100\\\\=7.69\%[/tex]
or
= 7.7%
So, the percentage decrease in the price of oil is 7.7%.

did they win?
Answer:
62.5%
Step-by-step explanation:
if they won 15 and lost 9 games then they played a total of 24 games (15+9). Then you just divid the number of wins (15) by the total number of games they played (24). SO, 15/24=0.652 or 62.5%

Answer:
[tex]2\frac{3}{4}[/tex] or 2.75, depending on what you need.
Step-by-step explanation:
Subtract $269 by the service fee ($60). This will be $209.Divide $209 by $76 to calculate hours.

Q1: In the isosceles triangle below the legs are twice the
length of the base. The perimeter is 100 cm. What are the
dimensions of the isosceles triangle?
Answer:
The base of the triangle has a size of 20 cm, while each side has a size of 40 cm.
Step-by-step explanation:
An isosceles triangle is one that has two sides with an identical value, and one side with a different value from the previous ones. Thus, in the case the base will have a different value from the sides. In this regard, the perimeter (the sum of the sides) of the triangle is 100 cm, and the longest sides are twice the size of the base. Therefore, to determine the value of each side of the triangle, the following calculation must be performed:
X + 2X + 2X = 100
5X = 100
X = 100/5
X = 20
Thus, the base of the triangle has a size of 20 cm, while each side has a size of 40 cm.

A. (4.5, 5.0)
B. (5.6, 4.2)
C. (4.8, 4.4)
D. (4.2, 5.6)
Answer:
[tex]M(x,y) = (4.8,4.4)[/tex]
Step-by-step explanation:
Given
[tex]P(x_1,y_1) = (6,2)[/tex]
[tex]Q(x_2,y_2) = (3,8)[/tex]
[tex]m:n = PM:MQ = 3 : 2[/tex]
Required
Determine the coordinates of M
To solve this, we make use of the following partition formula:
[tex]M(x,y) = (\frac{nx_2+mx_1}{n+m},\frac{ny_2+my_1}{n+m})[/tex]
Substitute values for m, n, x's and y's
[tex]M(x,y) = (\frac{2*3+3*6}{2+3},\frac{2*8+3*2}{2+3})[/tex]
[tex]M(x,y) = (\frac{24}{5},\frac{22}{5})[/tex]

If 3+a=4-b and 4+b=7+a, what is 3-a?
Step-by-step explanation:
3+a=4-b
4+b=7+a
a=1-b
4+b=7+1-b
2b=4
b=2
a=1-2= -1
3-a= 3- -1= 3+1=4
3-a=4
Answer:
The answer is 4.
Step-by-step explanation:
First, you have to form simultaneous equations :
[tex]3 + a = 4 - b[/tex]
[tex]a + b = 1 - - - (1)[/tex]
[tex]4 + b = 7 + a[/tex]
[tex]a - b = - 3 - - - (2)[/tex]
Next, you have to solve it :
[tex](1) - (2)[/tex]
[tex]a + b - (a - b) = 1 - ( - 3)[/tex]
[tex]2b = 4[/tex]
[tex]b = 2[/tex]
[tex]sub \: \: b \: = 2 \: \: into \: \: (1)[/tex]
[tex]a + 2 = 1[/tex]
[tex]a = 1 - 2[/tex]
[tex]a = - 1[/tex]
Lastly, you have to substitute a-value into the expression :
[tex]3 - a = 3 - ( - 1) = 4[/tex]
Caleb is making lemonade and cookies for the school bake sale. He has 10 cups of
sugar. He needs two cups of sugar for lemonade. Each batch of cookies uses 11/2 cups
of sugar. What is the maximum number of cookie batches he can make?
Answer:
He can make only one batch of cookies.
Step-by-step explanation:
Just by mental math you can say he can make maximum one batch of cookies.
Total sugar = 10 cups
sugar used for lemonade = 2 cups
leftover sugar = 8 cups
For 1 batch of cookie sugar needed = 11/2
which means 5 and 1/2 cups
And he's just left with 8 cups of sugar after lemonade
8 - 5 1/2 = 2 1/2 which is not enough for 2nd batch
That means the maximum number of cookies batches is 1.
Another way to solve it by inequality:
2+Il/2 X < 10
11/2 X < 8
11X < 16
X < 1 6/11
So he can make only one batch of cookies.

Jamey has 4 quarters, some dimes, and some pennies. If the ratio of quarters to dimes is 8 : 6 and the ratio of pennies to dimes is 7 : 3, then how many pennies does Jamey have?
Answer:
7
Step-by-step explanation:
the ratio of [pennies to dimes is 7:3.... 7 represents pennies and 3 dimes
By the given ratio, Number of pennies does Jamey have are 7.
What is a ratio?"A ratio compares values. A ratio says how much of one thing there is compared to another thing."
According to the question
Jamey has 4 quarters, some dimes, and some pennies.
Ratio of quarters to dimes is 8:6
So, [tex]\frac{4}{d}=\frac{8}{6}[/tex]
⇒ [tex]8d = 6(4)[/tex]
⇒ [tex]d=\frac{6}{2}[/tex]
⇒ [tex]d=3[/tex]
Ratio of pennies to dimes is 7 : 3
So, [tex]\frac{p}{d}=\frac{7}{3}[/tex]
By substituting d = 3
⇒ [tex]\frac{p}{3}=\frac{7}{3}[/tex]
⇒ [tex]p = \frac{7}{3}(3)[/tex]
⇒ [tex]p =7[/tex]
Hence, number of pennies does Jamey have are 7.

A person places $85800 in an investment account earning an annual rate of 8.5%,
compounded continuously. Using the formula V = Pert, where V is the value of the
account int years, P is the principal initially invested, e is the base of a natural
logarithm, and r is the rate of interest, determine the amount of money, to the nearest
cent, in the account after 9 years.
Answer:
$184383.7
Step-by-step explanation:
We are given that
Principal, P=$85800
Rate of interest, r=8.5%=0.085
Time, t=9 years
We have to find the amount of money after 9 years
[tex]V=Pe^{rt}[/tex]
Using the formula
[tex]V=85800e^{0.085\times 9}[/tex]
[tex]V=184383.7[/tex]
Hence, the amount of money after 9 years=$184383.7
In 1990, the cost of tuition at a large Midwestern university was $99 per credit hour. In 2003, tuition had risen to $268 per credit hour
Answer:
63%
Step-by-step explanation:
From the question, we aim to find the percent increase in the tuition
Given data
initial cost= $99 per credit hour
Final cost= $268 per credit hour
% increase= (Final - initial )/initial *100
substitute
% increase= (268- 99 )/268 *100
% increase= 169 /268 *100
% increase= 0.630*100
% increase= 63%
Hence the increase in the tuition from 1990 to 2003 is 63%

A telephone pole has a wire attached to its top that is anchored to the ground. The distance from the bottom of the pole to the anchor point is 51 feet less than the height of the pole. If the wire is to be 24 feet longer than the height of the pole, what is the height of the pole?
Answer:
Height is 135 ft
Step-by-step explanation:
Notice that wire, pole, and ground form a right angle triangle, for which we name h = height of the pole one of the legs (the horizontal leg) is h - 51. The wire (which is the hypotenuse of the right angle triangle is: h + 24.
Then we can use the Pythagorean theorem to solve for the height (h):
h^2 + (h - 51)^2 = (h + 24)^2
h^2 + h^2 -102 h + 2601 = h^2 + 48 h + 576
grouping all terms on the left of the equal sign, we get:
h^2 -150 h + 2025 = 0
This gives two possible answers:
h = 135
and
h = 15
We opt for h = 135, because the other solution will render a negative leg for the triangle.
