Answer:
A. 30
B. 6
Step-by-step explanation:
We'll use P for Penny's age and B for Benny's age. When Penny is 24, Benny will be 1.25 her age. Thus:
B = 1.25 * 24
(benny is 25% older than her)
So Benny's age then will be 1.25 * 24 = 30.
When Benny is 30, Penny will be 24. This means that he is older than her by 6 years. Think about it for a second: Benny will always be 6 years older than her. You can write that as:
B = P + 6
If Benny is 12 years old now,
12 = P + 6
Subtract 6 from both sides and you get
6 = P
or P = 6
Penny is 6 years old when Benny is 12.

Answer:362
Step-by-step explanation:
You need to multiply
Answer:
126
Step-by-step explanation:
you add them all up and the sides that don't have the number there's already info about it it's like this
18 x 3 + 30 + 24 + 18 = 126
and you don't know how to do 18 x 3 lol it's 54
y=x+3
y=1/3x-5
solve and graph
Answer:
(-9, -12)
Step-by-step explanation:
Given the expressions
y=x+3
y=1/3x-5
Equating both expressions;
y = y
x + 3 = 1/3x - 5
x - 1/3x = -5 -3
2/3 x = -8
x/3 = -4
x = -12
Since
y = x+ 3
y = -12 + 3
x = -9
Hence the required solution is (-9, -12)
Will mark brainliest please help ASAP ASAP A bag contains 10 marbles.Four of them are red, three blue two white, and one yellow. A marble is drawn at random. what is the probability that it is red? Make sure you reduce your answer.
Answer: 2/5 or 40%
Step-by-step explanation:
10 total
4 red
4/10 are red
as a reduced fraction: 2/5
as a percent: 40%
Answer:
40%
Step-by-step explanation:
4/10 marbles are red therefore there is a 40 % chance you get a red marble
4/10 = .4
.4 x 100% = 40 %

4. Find the value of x in the given parallelogram.
(2x+5)*
1159
Your answer
Answer:
x = 55
Step-by-step explanation:
Use the property of a parallelogram,
" Opposite interior angles of a parallelogram are equal in measure"
By this property, opposite angles given in the figure will be equal.
(2x + 5)° = 115°
2x = 115 - 5
2x = 110
x = [tex]\frac{110}{2}[/tex]
x = 55
Therefore, x = 55 will be the value.
The vertices of triangle PQR are given in the standard (x,y) coordinate plane below. What is the area, in the square coordinate units, of triangle PQR?
Answer:
Area = 12
Step-by-step explanation:
Given
See attachment
Required
Area of [tex]\triangle PQR[/tex]
From the attached image, we have:
[tex]P = (6,10)[/tex]
[tex]Q = (10,8)[/tex]
[tex]R = (6,4)[/tex]
The area is then calculated as:
[tex]A = \frac{1}{2}|(x1y2 - x2y1) + (x2y3 - x3y2) + (x3y1 - x1y3)|[/tex]
So, we have:
[tex]A = \frac{1}{2}|(6*8 - 10*10) + (10*4 - 6*8) + (6*10 - 6*4)|[/tex]
Using a calculator:
[tex]A = \frac{1}{2}|-24|[/tex]
Remove absolute bracket
[tex]A = \frac{1}{2} * 24[/tex]
[tex]A = 12[/tex]

PLEASE HELP!! what is the area of the regular polygon
Question:
What is the area of the regular polygon
Answer:
72Step-by-step explanation:
Since the radius is 6 the Length/Width should also be 6 so the polygon has 6 sides so 6/3 = 2 x 6 = 12 x 6 = 72
72 is your answer
90 POINTS The difference of sample means of two populations is 55.4, and the standard deviation of the difference of sample means is 28.1. Which
statement is true if we are testing the null hypothesis at the 95% confidence level?
OA. The difference of the two means is significant, so the null hypothesis must be rejected.
OB The difference of the two means is significant, so the null hypothesis must be accepted.
Ос. The difference of the two means is not significant, so the null hypothesis must be rejected.
OD. The difference of the two means is not significant, so the null hypothesis must be accepted.
Answer:
answer is D
The difference of the two means is not significant, so the null hypothesis must be accepted.

A regular polygon has an interior angle of 171 degrees. Show your work. (3 points for work, 3 points
for correct answers)
a) How many sides does it have?
b) What is the sum of the interior angles?
c) What is the measure of one of its exterior angles?
Answer:
a) 40 sides
b) 6840
c) 9 gegrees
Step-by-step explanation:
interior angle= (n-2)180
n
[tex] (n - 2)180 \div n = 171 \\ 180n - 360 = 171n \\ 180n - 171n = 360 \\ 9n = 360 \\ n = 360 \div 9 = 40 \\ [/tex]
so total number of sides is 40
b) Sum of interior angles= (n-2)×180
(40-2)×180
38×180
6840
c) Exterior angle = 360 ÷ n
360÷40 =9 degree

El punto p se muestra en la recta numerica.
La distancia entre el punto Q y el punto P es de 6 1/2 unidades . Que numero podria representar el punto Q ?
Answer:
2 1/2 o 10 1/2
Step-by-step explanation:
q podría estar 6.5 unidades a la derecha ... oa la izquierda ... del punto p.
a la derecha: p + q ⇒ -4 + (6 1/2) = 2 1/2
a la izquierda: p - q ⇒ -4 -(6 1/2) = -10 1/2
