What is the value of the expression below when f = 2.5
8 + 4f
A. 132
B. 18
C. 42
D. 28
Answer:
x = 48
Step-by-step explanation:
(x - 6)⁰ + ( 2x + 42)⁰ = 180⁰
x - 6⁰ + 2x + 42⁰ = 180⁰
x + 2x - 6⁰ + 42⁰ = 180⁰
3x + 36⁰ = 180⁰
3x + 36⁰ - 36⁰ = 180⁰ - 36⁰
3x = 144⁰
3x / 3 = 144⁰ / 3
x = 48

Jill was looking at a picture of herself and 3 friends. She measured the height of her image as 10 centimeters. If Jill is actually 60 inches tall, which equation can she use to find h, the actual height in inches, of one of her friends who is c centimeters tall in the picture?
The actual height in inches,will be [tex]\dfrac{1}{6} c[/tex] of one of her friends who is c centimeters tall in the picture
What is hieght?Height is measure of vertical distance, either vertical extent (how "tall" something or someone is) or vertical position.
lets call the height x :
[tex]\dfrac{10}{60} = \dfrac{h}{x}[/tex]
[tex]x = \dfrac{1}{6} h[/tex]
Hence the actual height in inches,will be [tex]\dfrac{1}{6} c[/tex] of one of her friends who is c centimeters tall in the picture.

Question 22: 4 pts Find the probability of rolling a 4 on a number cube and then choosing a red ball at random from a bag of 8 blue and 6 red balls.
Answer:
1/14
Step-by-step explanation:
a four out of possible 6 rolls = 1/6
6 red out of 14 balls 6/14
1/6 * 6/14 = 1/14
The Probability of rolling a 4 on a number cube and then choosing a red a ball at random is 1/14.
What is Probability?Probability is "possibility that deals with the chance of occurrence of random event" .
According to the question,
A cube has 6 faces that is (1,2,3,4,5,6). Total number of faces n(s) = 6.
Probability formula = (Number of favorable event)/(Total number of event).
Probability of taking 4, P(4) = 1/6.
A bag containing 8 blue and 6 red balls. Total number of balls in a bag n(s) = 14.
Probability of taking red balls P(red balls) = 6/14.
In order to find that probability of rolling a 4 on a number cube and then choosing a red a ball at random only if multiply P(4) by P(red balls).
P(4) × P(red balls) = [tex]\frac{1}{6}[/tex] × [tex]\frac{6}{14}[/tex] = [tex]\frac{1}{14}[/tex].
Hence, probability of rolling a 4 on a number cube and then choosing a red a ball at random is 1/14.

Answer:
85°
Step-by-step explanation:
The two angles are known as vertical angles, which are always congruent
Answer:
∠DEB = 85°
Step-by-step explanation:
Vertical Angle Theorem
When two straight lines intersect, they form two pairs of angles. The vertically opposite (non-adjacent) angles are congruent.
Angles AEC and DEB are vertically opposite angles, therefore:
∠AEC = ∠DEB
As ∠AEC = 85° then ∠DEB = 85° also.
a 1 Mrs. Erskine spent $40.50 for a pair of shoes, $56.95 for jeans, and $25.75 for a shirt.

b) cost of ticket = $13
max profit = $3380
number of tickets sold = 260
Step-by-step explanation:
Profit equation: [tex]P=20(15-x)(11+x)[/tex]
Part (a)Vertex form of quadratic equation: [tex]y=a(x-h)^2+k[/tex]
(where (h, k) is the vertex and [tex]a[/tex] is some constant)
First, write the given profit equation in standard form [tex]ax^2+bx+c[/tex]:
[tex]\begin{aligned}\implies P&=20(15-x)(11+x)\\& = 20(165+4x-x^2)\\& = -20x^2+80x+3300\end{aligned}[/tex]
Factor -20 from the first two terms:
[tex]\implies P=-20(x^2-4x)+3300[/tex]
Complete the square:
[tex]\implies P=-20(x^2-4x+4)+80+3300[/tex]
[tex]\implies P=-20(x-2)^2+3380[/tex]
Part (b)The vertex of the profit equation is (2, 3380).
Therefore, the cost of the ticket is when x = 2 ⇒ $11 + 2 = $13
The maximum profit is the y-value of the vertex: $3380
The number of tickets sold at this price is:
⇒ max profit ÷ ticket price
= 3380 ÷ 13
= 260
In 1900 Kansas City had a population of 163,000In 2020 it has a population of 1,686,000Show me exponential growthHow many years after 1900Did it take for the population to double
The exponential growth is 1.95% and after 35.72 years the population will double.
What is an exponential function?It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent [tex]\rm y = a^x[/tex]
where a is a constant and a>1
Let's suppose the exponential growth function is:
[tex]\rm y = Ae^{rt}[/tex]
A = 163,000
y = 1,686,000
t = 2020 – 1900 = 120 years
Plug all the values in the function:
[tex]\rm 1686000 = 163000e^{120r}[/tex]
[tex]\rm e^{120r} = 10.343[/tex]
Taking ln both side and solving:
r = 0.0194
r = 1.946 ≈ 1.95%
[tex]\rm 2A = Ae^{0.0194t}[/tex] (the population to double)
After solving:
t = 35.72 years
Thus, the exponential growth is 1.95% and after 35.72 years the population will double.

14 2/3 yards into feet?
Answer:
44.000000001 (exact) or rounded up 44
Step-by-step explanation:
14.666666667*3 because 1 yard= 3 feet
One yard is 3 feet, which means we will have to mutliple 14 2/3 by 3.
14 x 3 =42
2/3 of a yard is 2 feet, which means we must add 2 to 42--->
42+2= 44
14 2/3 yards is 44 feet.

Use the Venn diagram to calculate probabilities.
Circles A, B, and C overlap. Circle A contains 3, circle B contains 9, and circle C contains 6. The overlap of A and B contains 1, the overlap of B and C contains 4, and the overlap of C and A contains 7. The overlap of the 3 circles contains 6. Number 8 is outside of the circles.
Which probability is correct?
P(A|B) = One-half
P(B|A) = StartFraction 7 Over 20 EndFraction
P(A|C) = StartFraction 6 Over 23 EndFraction
P(C|A) = StartFraction 13 Over 17 EndFraction
Using the probability concept and the Venn diagram described, the correct option is given by:
P(C|A) = 13/17.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
P(A|B) is given by the sum of the values that involve both A and B by the sum of all values that involve B, hence:
D = 1(overlap of A and B) + 6(Overlap of the 3).T = 9 + 1 + 4 + 6 = 20.Hence:
P(A|B) = 7/20.
Following the same logic, we have that:
P(B|A) = (1 + 6)/(3 + 1 + 7 + 6) = 7/17P(A|C) = (7 + 6)/(6 + 4 + 7 + 6) = 13/23P(C|A) = (7 + 6)/ (3 + 1 + 7 + 6) = 13/17.Hence the last option is correct.
