Answer:
$8,775
Step-by-step explanation:
The amount due is given by the formula ...
A = P(1 +rt)
where P is the principal amount, r is the annual rate, and t is the number of years.
A = $6,500(1 +0.07×5) = $6,500(1.35) = $8,775

This is falsex = 5 is a solution to the equation 11 - x < 7- PacificNorthwest
Answer:
x=5 is the correct answer
Step-by-step explanation:
First we start off to see if x=3 could work (put the x value in)
11-3<7
(11-3=8)
8<7 This is false
Now lets try the other one-
11-5<7
(11-5=6)

Explanation:
Segments DB and DC are the same length. This makes triangle BCD to be isosceles. Recall that the base angles of any isosceles triangle are congruent angles. The base angles are opposite the congruent sides.
So because DB = DC, this makes B = C the congruent base angles in question. Let's say they are x for now.
Also recall that for any triangle, the three angles always add to 180 degrees.
B+C+D = 180
x+x+44 = 180
2x+44 = 180
2x = 180-44
2x = 136
x = 136/2
x = 68
So angles B and C, of triangle BCD, are 68 degrees each.
This leads to angle BCD to be 68 degrees as well.
Now we'll turn to the Tangent-Chord Theorem. This says that the angle made between a chord and a tangent is the same measure as the inscribed angle that is opposite the chord.
In this case,
AB is the tangentDB is the chord we want to focus onangle ABD is the angle between the chord and tangentangle BCD is the angle opposite the chordSo because angle BCD is 68 degrees, so is angle ABD.

Answer:
h(x) ≤ 5
Step-by-step explanation:
The function and boundaries given are;
h(x) = x + 2, x < 3
And ;
h(x) = -x + 8, x ≥ 3
Now,in the first condition, the maximum value of x will be 2. This means the maximum value of h(x) there is;
h(2) = 2 + 2 = 4
For the second condition, x ≥ 3. Thus, the maximum value of x is 3.
This means that the maximum value of h(x) here is;
h(3) = -3 + 8 = 5
Foe the 2 conditions combined it is clear that the maximum value of h(x) is 5.
Thus,we can say; h(x) ≤ 5

One gallon of paint covers 400 square feet. What is the least amount of paint needed to paint the walls of a room in the shape of a rectangular prism with a length of 20 feet, a width of 16 feet, and a height of 10 feet? Write your answer as a decimal.
Answer:
1.8 gallons
SEE NOTE BELOW*
Step-by-step explanation:
2x10x16=320
2x20x10=400
400+320=720
720÷400=1.8 gallons
NOTE* This would be painting the four walls. If you include the floor and ceiling:
2x16x20=640
720+640=1360
1360÷400=3.4 gallons
The least amount of paint needed to paint the walls of a room in the shape of a rectangular prism is 1.8 gallons (2 gallons approx).
What is rectangular prism?Actually, prisms get their name from the way their faces are shaped. Therefore, a rectangular prism is just a prism with rectangular faces. Although it is a closed, three-dimensional object, two rectangles serve as its foundation.
The formula to calculate the total surface area of a rectangular prism is given as,
TSA of rectangular prism = 2(lb + bh + lh)
Where, l is length, b is breadth and h is the height of the rectangular prism.
Calculation for the paint required for rectangular prism:
The area of the sides of prism to be painted is
Area A = 2×(length×height) + 2×(breadth×height)
Length = 20 feet
Breadth = 16 feet
Height = 10 feet
A = 2×(20×10) + 2×(16×10)
A = 720 sq. feet
Now, the paint need for painting 400 sq. feet is 1 gallon.
Thus, paint required for 720 sq. feet is,
=> 720 ft² / 400 ft² /gal = 1.8 gal
Therefore, for painting rectangular prism, the amount of paint required is 1.8 gal.

1) A ball is dropped from a height of 50 feet. How long after it is dropped will it reach a height of 18 feet?
Answer: 1.41 seconds
Step-by-step explanation:
The problem gives the initial velocity by saying "dropped." This indicates a velocity of zero. Acceleration can also be found because the object is in free fall. It would experience the acceleration of gravity. We can use the kinematic equation:
[tex](y_f-y_i)=V_it+\frac{1}{2}at^2[/tex]
The velocity term completely cancels because the object was dropped with an initial velocity of 0.
[tex](18-50)=\frac{1}{2} (32.17)t^2\\[/tex]
[tex]-32=-16.085t^2\\t=\sqrt{1.989} =1.41s[/tex]
In a large section of a statistics class, the points for the final exam are normally distributed, with a mean of 71 and a standard deviation of 7. Grades are assigned such that the top 10% receive A's, the next 20% received B's, the middle 40% receive C's, the next 20% receive D's, and the bottom 10% receive F's. Find the lowest score on the final exam that would qualify a student for an A, a B, a C, and a D.
Answer:
The lowest score on the final exam that would qualify a student for an A is 80.
The lowest score on the final exam that would qualify a student for a B is 74.68.
The lowest score on the final exam that would qualify a student for a C is 67.33.
The lowest score on the final exam that would qualify a student for a D is 62.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Mean of 71 and a standard deviation of 7.
This means that [tex]\mu = 71, \sigma = 7[/tex]
Grades are assigned such that the top 10% receive A's, the next 20% received B's, the middle 40% receive C's, the next 20% receive D's, and the bottom 10% receive F's.
This means that:
90th percentile and above: A
70th percentile and below 90th: B
30th percentile to the 70th percentile: C
10th percentile to the 30th: D
Lowest score for an A:
Top 10% receive A, which means that the lowest score that would qualify a student for an A is the 100 - 10 = 90th percentile, which is X when Z has a pvalue of 0.9, so X when Z = 1.28.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.28 = \frac{X - 71}{7}[/tex]
[tex]X - 71 = 7*1.28[/tex]
[tex]X = 80[/tex]
The lowest score on the final exam that would qualify a student for an A is 80.
Lowest score for a B:
70th percentile, which is X when Z has a pvalue of 0.7, so X when Z = 0.525.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.525 = \frac{X - 71}{7}[/tex]
[tex]X - 71 = 7*0.525[/tex]
[tex]X = 74.68[/tex]
The lowest score on the final exam that would qualify a student for a B is 74.68.
Lowest score for a C:
30th percentile, which is X when Z has a pvalue of 0.3, so X when Z = -0.525.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-0.525 = \frac{X - 71}{7}[/tex]
[tex]X - 71 = 7*(-0.525)[/tex]
[tex]X = 67.33[/tex]
The lowest score on the final exam that would qualify a student for a C is 67.33.
Lowest score for a D:
10th percentile, which is X when Z has a pvalue of 0.1, so X when Z = -1.28.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-1.28 = \frac{X - 71}{7}[/tex]
[tex]X - 71 = 7*(-1.28)[/tex]
[tex]X = 62[/tex]
The lowest score on the final exam that would qualify a student for a D is 62.

d varies jointly with w and p and inversely with u
In your equation, use k as the constant of proportionality.
Answer:
huh?
Step-by-step explanation:
If D varies jointly with w and p and inversely with u, it can be written as D = (kwp)/u, where k is the constant of proportionality.
What is proportion?A mathematical comparison of two numbers is known as proportion. If two sets of given numbers increase or decrease in the same ratio, the ratios are said to be directly proportional to each other, according to proportion.
How to solve this problem?Given that D varies jointly with w and p. Then it can be written as
D ∝ w × p ...(1)
Again D varies inversely with u.
Then, D ∝ 1/u ...(2)
From (1) and (2), D ∝ (wp)/u ...(3)
We can take k as the constant of proportionality.
So, (3) becomes, D = k(wp/u) = (kwp)/u
Therefore, if D varies jointly with w and p and inversely with u, it can be written as D = (kwp)/u, where k is the constant of proportionality.

2(3 + 3y) + y = 11
2(3 + 3y) + y = 11
First, apply the distributive property:
2(3 + 3y) + y = 11
6 + 6y + y = 11
6 + 7y = 11
Substract 6 from both sides:
