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?
Answers
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 total of 328 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times the
number of adult tickets sold. How many adult tickets were sold?
Answers
Answer:
246 adult tickets were sold
Step-by-step explanation:
System of equations:
Variables:
x = number of adult tickets sold
y = number of student tickets sold
There were a total of 328 tickets sold, thus:
x + y = 328
The number of student tickets sold was three times the number of adult tickets sold, thus:
y = 3x
Substituting in the first equation:
x + 3x = 328
Simplifying:
4x = 328
Dividing by 4:
x = 328/4
x = 82
y = 3*82= 246
246 adult tickets were sold

(33 - 9x)° + 48° = 180°
33 - 9x + 48 = 180
81 - 9x = 180

x = - 11
m∠B = [33 - 9(- 11)]° = (33 + 99)° = 132°

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
Answers
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%

length of the base. The perimeter is 100 cm. What are the
dimensions of the isosceles triangle?
Answers
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.

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

Answers
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

C. (4.8, 4.4)
D. (4.2, 5.6)
Answers
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]
[tex]M(x,y) = (4.8,4.4)[/tex]
