A bank pays 3% annual simple interest on CDs (certificates of deposit) of $25,000. The Branson family
invests in 3 of the $25,000 CDs. How much interest does the family make in one year?
O A $22.50
OB $22,500.00
OC $2,250.00
OD $225.00
Answer:
Total interest in 1 year = $2,250
Step-by-step explanation:
Given:
Rate of simple interest = 3% = 0.03
Amount of investment = $25,000
Number of investment = 3
Find:
Total interest in 1 year .
Computation:
Simple interest = Amount of investment × Rate of simple interest
Simple interest = $25,000 × 0.03
Simple interest = $750
Total interest in 1 year = Simple interest × Number of investment
Total interest in 1 year = $750 × 3
Total interest in 1 year = $2,250
write the equation for a paraloba with a focus at (7,2) and a directrix at y=-2
Answer:
y = (x-7)^2 / 8
Step-by-step explanation:
The focus to vertex distance is (2-(-2))/2 = 2 and the parabola open's upwards.
Thus: a = 1/(4·2) = 8, vertex at (7,0).
This means that:
y = (x-7)2/8

m∠ABD is a straight angle m∠CBD=8x+16 m∠ABC=6x−60
Answer:[tex]36^{\circ}[/tex]
Step-by-step explanation:
A straight angle means that the angle has a measure of 180 degrees. Therefore:
[tex]CBD+ABC=180 \\\\(8x+16)+(6x-60)=180 \\\\14x-44=180\\\\14x=224\\\\x=16\\\\6x-60=6(16)-60=96-60=36[/tex]
Hope this helps!
Answer:
m∠ABC = 36 degrees
Step-by-step explanation:
8x + 16 + 6x - 60 = 180 Add both angles to equal 180
14x - 44 = 180
+ 44 + 44 Add 44 to both sides
14x = 224 Divide both sides by 14
x = 16
Plug this into the equation for angle ABC
6(16) - 60 Multiply
96 - 60 Subtract
m∠ABC = 36
Use the fraction bar interactive tool to find the lowest common denominator before subtracting 2 3 from 5 6 . What is the lowest common denominator? Rewrite the difference as a sum of the fractions using the lowest common denominator. What is the answer?
Answer:
What is the lowest common denominator?
✔ 6
Rewrite the difference as a sum of the fractions using the lowest common denominator.
✔ 5/6 + (–4/6)
What is the answer?
✔ 1/6
Step-by-step explanation:
Fractions can be combined by taking their LCMs
The lowest common denominator is 6The new expression is [tex]\mathbf{-\frac{4}{6} + \frac{5}{6}}[/tex]The numbers are given as:
[tex]\mathbf{\frac{2}{3}\ and\ \frac{5}{6}}[/tex]
The denominators are 3 and 6.
Factor both numbers;
[tex]\mathbf{3 = 1\times 3}[/tex]
[tex]\mathbf{6 = 1 \times 2 \times 3}[/tex]
So, the LCM is:
[tex]\mathbf{LCM = 1 \times 2 \times 3}[/tex]
[tex]\mathbf{LCM = 6}[/tex]
The lowest common denominator is 6
The expression is represented as:
[tex]\mathbf{ - \frac{2}{3}\ + \ \frac{5}{6}}[/tex]
Rewrite as:
[tex]\mathbf{ - \frac{2}{3}\ + \ \frac{5}{6} = -\frac{4}{6} + \frac{5}{6}}[/tex]
Hence, the new expression is [tex]\mathbf{-\frac{4}{6} + \frac{5}{6}}[/tex]

I've ordered this shed. It is 2 meters wide, 3.25 meters long and 2 meters tall to the roof line. From the roof line to the peak is 0.8 meters high. I would like a 2nd floor or loft to increase the storage space. Please calculate the total amount of storage.
Answer:
18.2 cubic meters.
Step-by-step explanation:
From the measurements they give us, we assume that the shed has the shape of a rectangular prism, however, to calculate the amount of storage, we must calculate the volume.
The volume would be:
V = height * width * length
According to the statement height = 2, width = 2 and length = 3.25
V = 2 * 2 * 3.25
V = 13
That is, the volume of the shed is 13 cubic meters, but then they mention that the roof line to the peak is 0.8 meters high, which means that the volume can increase, the new volume would be changing the height = 2 + 0.8 = 2.8, the other values remain the same:
V = 2.8 * 2 * 3.25
V = 18.2
That is to say that when adding that part, the volume that is to say total amount of storage is 18.2 cubic meters.

What is the slope of the line through (-4,2)(−4,2)left parenthesis, minus, 4, comma, 2, right parenthesis and (3,-3)(3,−3)left parenthesis, 3, comma, minus, 3, right parenthesis?
Answer:
The slope of the line through the points is -5/7
Step-by-step explanation:
Here, we want to calculate the value of the slope through the lines
Mathematically;
m = y2-y1/(x2-x1)
Where (x1,y1) = (-4,2)
and (x2,y2) = (3,-3)
Substituting these values, we have;
m = (-3-2)/(3-(-4)) = -5/7 = -5/7
The slope of the line through (-4, 2) and (3, -3) is; -5/7
According to the question;
We are required to determine the slope of the line through the points given.The slope, m of the line is given mathematically as;
m = (y2 -y1)/(x2 - x1)Therefore, in this case;
Slope, m = (-3 - 2)/(3 -(-4))Slope, m = -5/7

I attached the question that I need help with.
Step-by-step explanation:
that's it hope u understood
Answer:
Step-by-step explanation:
Your answer for x = 25.35 is correct.
Since the night must be an integer, you need to take 26 as your final answer. b) for y = 1500, you solve for x to consider which one is better.
for plan A, y = 87 x + 2129, you have to pay $2129 before starting the trip, hence $1500 is NOT enough to pay.
for plan B, y = 171x and y = 1500, hence x = 8.77. So, with $1500 you can travel for 8 nights.

Locate the ordered pair (0, –6). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points.
Step-by-step explanation:
The answer is the first one because the slope is technically [tex]\frac{2}{1}[/tex]

Sofi is competing in a long jump competition. His first jump is 5.25 m. Your best jump is 8% more than this. However, his best jump is 10% lower than the winning jump. Calculate the length of the winning jump.
Answer: 6.3 m
Step-by-step explanation:
"8% more" = 1.08 (which is 1+0.08). "10% less" = 0.90 (which is 1-0.10).
first = 5.25
her_best = 1.08*first
her_best = 0.90*winning
Substitute to determine the winning jump's length.
winning = 1.08*5.25/0.90 = 6.3
So, the winning jump was 6.3 meters.
A number is selected from the set {1, 2, 3, 5, 15, 21, 29, 38, 500}. If equal elemental probabilities are assigned, what is the probability that the number chosen is either less than 29 or odd? 6/9 7/9 8/9
Answer:
The required probability is [tex]\frac{7}{9}[/tex].
Step-by-step explanation:
Set given is:
S = {1, 2, 3, 5, 15, 21, 29, 38, 500}
Total number of elements in set, [tex]n(S)[/tex] = 9
Let A be the event that the number is less than 29 ({1, 2, 3, 5, 15, 21}).
Number of items in the event A, [tex]n(A)[/tex] = 6
Probability of event A,
[tex]P(A) = \dfrac{n(A)}{n(S)}}=\dfrac{6}{9} \Rightarrow \dfrac{2}{3}[/tex]
Formula for probability of any event E:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
Let B be the event that the number is odd (either of {1,3,5,15,21,29}).
Number of items in the event B, [tex]n(B)[/tex] = 6
Probability of event B,
[tex]P(B) = \dfrac{n(B)}{n(S)}}=\dfrac{6}{9} \Rightarrow \dfrac{2}{3}[/tex]
The event A and B have a few elements in common, i.e. numbers less than 29 which are odd as well.
The common elements are represented as:
[tex]A \cap B = \{1, 3, 5, 15, 21\}[/tex]
[tex]n(A\cap B) = 5[/tex]
[tex]P(A \cap B ) = \dfrac{n(A \cap B)}{n(s)}\\\Rightarrow P(A \cap B) = \dfrac{5}{9}[/tex]
To find probability of selecting a number which is either less than 29 (event A) or odd (event B),
We have to find [tex]P(A\ or \ B)[/tex] which is represented as [tex]P(A \cup B)[/tex] and the formula is:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)\\\Rightarrow \dfrac{2}{3} + \dfrac{2}{3} - \dfrac{5}{9}\\\Rightarrow \dfrac{12-5}{9}\\\Rightarrow \dfrac{7}{9}[/tex]
The required probability is [tex]\frac{7}{9}[/tex].

Answer:
8
Step-by-step explanation:
9n - 7 = 3 + 8n - 2
Combine like factors.
9n - 7 = 8n + 1
Subtract 8n from both sides
n - 7 = 1
Add 7 to both sides.
n = 8

Answer:
80.4 =x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions

tan 15 = x / 300
Multiply each side by 300
300 tan 15 = x
80.38475773=x
To the nearest tenth
80.4 =x
Answer:
80.4
Step-by-step explanation:
use tan x = opp/adj
tan 15° = x/300 multiply by 300 on both sides
tan 15° * 300 = x
x = 80 .38 ≈80.4

Answer:
i. x = -0.5 and 1.5; ii. x = 1.5
Step-by-step explanation:
For part i, we can take a look at the x-intercepts of the parabola. When a quadratic equation equals 0, this means that we are taking a look at its roots, or solutions.
The parabola intersects the x-axis at approximately -0.5 and 1.5. We can say this is an estimate to the solutions.
For part ii, the question is asking the x value that makes the function equal 2. We just look at the point where y = 2, which happens to be 1.5. So when x = 1.5, y = 2, which is what we want.
I hope this helps!
