Answer:
Pennies = 80
Nickels = 160
Step-by-step explanation:
Two equations representing the relation between numbers of pennies and nickels have been given.
0.01p + 0.05n = 8.80 ---------(1)
n = 2p -----(2)
By substituting the value of n from equation (2) in equation (1).
0.01p + 0.05(2p) = 8.80
0.01p + 0.1p = 8.80
0.11p = 8.80
p = [tex]\frac{8.8}{0.11}[/tex]
p = 80
By equation (2)
n = 2×80
n = 160

D
1>) 170°
1) 30°
1) 25°
1) 180°
Answer:
The answer is 30
Step-by-step explanation:
It is 30 because if there is 75 and the total needs to be 105 then you have to add 30+75+105! Thats the answer.
I got it right! :)
The CBD angle is 30 degrees.
What is an angle?An angle is formed when two straight lines or rays meet at a common endpoint.
Given that the measure of angle ABD is 105º and the measure of angle ABC is 75º.
According to the given figure, the relation between angles is given by
angle ABD = angle ABC + angle CBD
Let x be the angle CBD then
105 = 75 + x
i.e x = 105 - 75 = 30
Hence the angle CBD is 30°.

what is 3n+2(−2n−1)
Answer:
-n-2
Step-by-step explanation:
First, you need to distribute the 2 on the -2n and -1. So multiply the 2 by -2n and -1. You get = -4n-2.
You still have the 3n, so the equation will now look like: 3n-4n-2.
Combine like terms. 3n-4n= -1n or just -n.
Now you have -n-2.

Both tables have slope 2 (y increases two for every increase of 1 in x). First has y intercept 5, second 15 (19=2(2)+b). So our system is
y = 2x + 5
y = 2x + 15
Those are parallel lines, which never meet, so no solution.

Quadrilateral OPQR is inscribed inside a circle as shown below. What is the measure of angle P? You must show all work and calculations to receive credit. (10 points) Circle N is shown with an inscribed quadrilateral labeled OPQR. O is labeled 2x degrees. P is labeled y degrees. Q is labeled 2
Answer:
The measure of angle P is 43°
Step-by-step explanation:
If a quadrilateral is inscribed inside a circle, the sum of opposite angles are always equal to 180 degrees.
The angle POR is opposite to the angle PQR, and the angle OPQ is opposite to the angle ORQ.
So we have that:
mOPQ + mORQ = 180°
y + 3y + 8 = 180
4y = 172
y = 43°
So the measure of angle P is 43°.

Answer:
smaller x = -2
larger x = 4
vertex: (1, -9)
Step-by-step explanation:
To find the zeros of the function, set each value in parenthesis to 0 separately.
Smaller x:
(x+2) = 0
x = -2
Larger x:
(x-4) = 0
x = 4
To find the vertex of the parabola you need to find the x value between the zeros.
[tex]\frac{4 + (-2)}{2}[/tex] = [tex]\frac{2}{2}[/tex] = 1
Plug 1 in for x in the equation.
f(x) = ((1) + 2)((1) - 4)
f(x) = (3)(-3)
f(x) = -9
When x = 1, f(x) = -9, so the vertex of the parabola is at (1, -9).

Emma buys a house for £201 500
She sells the house for £213 590
What is the percentage profit Emma makes.
Answer:
6%
Step-by-step explanation:
[tex]\frac{213590 - 201500}{201500} = \frac{12090}{201500} = 6[/tex]
The percentage profit Emma makes. if, Emma buys a house for £201 500, and She sells the house for £213 590 is 6%.
What is percentage?As it is clear from the term per cent means measuring anything per hundred. For example, you get marks per 100 marks, so you get the percentage.
Given:
Emma buys a house for £201 500,
She sells the house for £213 590,
Calculate the profit as shown below,
Profit = Selling price of the house - Cost of house
Profit = 213 590 - 201 500
Profit = £12090
Calculate the percentage profit as shown below,
The percentage profit = Profit / Cost of house × 100
The percentage profit = 12090 / 201500 × 100
The percentage profit = 0.06 × 100
The percentage profit = 6%

A trapezoid has an area of 20 cm2 and a height z cm. The lengths of the parallel sides are (2z + 3) cm and (6z – 1) cm. Find the height, z, of the trapezoid. In your final answer, include all of the formulas and calculations necessary.
Answer: 2.11cm
Step-by-step explanation:
Given the following :
The lengths of the parallel sides are (2z + 3) cm and (6z – 1) cm
The area of trapezoid is calculated using the formula:
1/2(a + b) × h
Where ;
a = Length of side 1
b = length of side 2
h = height
Take a = (2z + 3) and b = (6z – 1), h = z
Therefore ;
1/2 (2z + 3 + 6z - 1) × z
Opening the bracket
(z + 1.5 + 3z - 0.5) × z
(4z + 1 ) × z = 20cm^2
4z^2 + z = 20cm^2
Using Quadratic formula:
4z^2 + z - 20 = 0
a = 4, b = 1, c = - 20
(-b±√b^2 -4ac) / 2a
Z = 2.11 or - 2.364
z cannot be negative, therefore,
Z = 2.11 cm

This question is incomplete because it lacks the appropriate options
Complete Question
Fifteen percent of the students at Central High take Spanish, 12% take French, and 4% take both. If a student is selected at random, what is the
probability that the student takes Spanish or French?
A 31%
B. 27%
C. 23%
D. 19%
Answer:
C. 23%
Step-by-step explanation:
At Central High
From the question, we are told that:
Spanish = 15%
French = 12%
Spanish and French = 4%
French or Spanish = unknown
Therefore, the probability that a student at random takes Spanish or French
= P(Spanish) + P(French) - P(Spanish and French)
= 15% + 12% - 4%
= 27% - 4%
= 23%
