Find the area of the above parallelogram
Answer:
30 units²
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
Here
b is the horizontal measure between 2 red points, that is 6
h is the vertical measure from the lower left point to the other horizontal line, that is 5, then
A = 6 × 5 = 30 units²
A 25 ft ladder leans against a building. The ladder’s base is 13.5 feet from the building. Find the angle of elevation, which the ladder makes with the ground.
Answer:
57.3°
Step-by-step explanation:
A 25 feet ladder leans against a building.
The ladder's base is 13.5 feet from the building.
The ladder, the wall of the building and the ground form a right-angled triangle of:
Hypotenuse = 25 feet
Base = 13.5 feet
We are to find the angle of elevation which the ladder makes with the ground (or rather the angle created by hypotenuse and base)
Let's say the angle = X°
According to a trigonometric equation;
cos X° = adjacent side ÷ hypotenuse = [tex]\frac{13.5}{25}[/tex] = 0.54
[tex]cos ^{-1} X[/tex] = 57.5=3° (Answer rounded up to nearest one decimal place).
∴ The angle of elevation = 57.3°
Jermaine earned $2000 during the summer. He plans to put the money in a
savings account and leave it for 40 years. The account will earn 9% simple
interest annually. What will the balance be after 40 years?
Please help!! This is a test and I need a good grade!!
Answer:9200
Step-by-step explanation: .09 * 2000 = 180 * 40 = 7200 + 2000 = 9200
Balance amount in Jermaine account after 40 years is equals to $9200.
What is simple interest?" Simple interest is the process of calculating amount of interest given on the principal amount at the rate of interest over period of time."
Formula used
S.I. = = (P × R × T) / 100
S.I.= Simple Interest
P = Principal amount
R = Rate of interest
T = Time
Total amount = P + S.I.
According to the question,
Given
P = $2000
R = 9%
T = 40 years
Substitute the given values in the formula we have,
Simple Interest = (2000 × 9 × 40) / 100
= $7200
Total balance amount after 40 years = $2000 + $ 7200
= $9200
Hence, balance amount after 40 years is equals to $9200.

Answer:
Line m and n are parallel lines that are intersected by a line
This means that corresponding angles in each line are equal to each other
This means that angle (3x+58) is equal to (5x)
now, we can solve for x and from there find the angle measure
(3x+58)=5x
3x-3x+58=5x-3x
58=2x
58/2=2x/2
29=x
if 29=x then 5(29)=5x
the angle measure of these angles is 145
Step-by-step explanation:
Answer:
Step-by-step explanation:
m // n and they are intersected by transversal.
Corresponding angles are equal
5x = 3x + 58
5x - 3x = 58
2x = 58

* Brittany's teacher tells her that she did well on the Statistics test - her z-score was 1.80 on the test. If the mean score on the test was a 75 with a standard
deviation of 10, find Brittany's score
Answer:
93
Step-by-step explanation:
Given that:
Brittany's Zscore = 1.8
Mean score (m) = 75
Standard deviation (s) = 10
Brittany's score (x) =?
Using the Zscore formula :
Zscore = (x - m) / s
1.8 = (x - 75) / 10
18 = x - 75
18 + 75 = x
93 = x
Hence, Brittany's score is 93
Jacks father drives to work in 30 minutes while driivng at his usual speed. When traffic is bad, he drives 30 miles per hour slower and the trip takes one hour longer. How far is Jack's father's work from home
Answer:
The distance of Jack's father's work from home is 22.5 miles.
Step-by-step explanation:
Given;
time it takes Jacks father at usual speed, t = 30 minutes = 0.5 hour
Jacks father speed when traffic is bad, = 30 mph slower
let the usual speed = v
let the distance of Jack's father's work from home = y
When traffic is normal;
[tex]v = \frac{y}{0.5 } ---- equation \ (1)[/tex]
When traffic is bad;
[tex]v - 30 \ mph = \frac{y}{1 \ + \ 0.5} \\\\v -30 = \frac{y}{1.5} \\\\v= 30 +\frac{y}{1.5} ----equation \ (2)[/tex]
Solve equation (1) and (2) together;
[tex]\frac{y}{0.5} = 30 \ + \ \frac{y}{1.5} \\\\y = 0.5(30 \ + \ \frac{y}{1.5})\\\\y = 15 + \frac{y}{3} \\\\y - \frac{y}{3} = 15\\\\\frac{3y-y}{3} =15\\\\\frac{2y}{3} =15\\\\2y = 3(15)\\\\2y = 45\\\\y = \frac{45}{2} \\\\y = 22.5 \ miles[/tex]
Therefore, the distance of Jack's father's work from home is 22.5 miles.
The required distance of Jack's father's work from home is y = 22.5miles.
Given that,
Jacks father drives to work in 30 minutes while driving at his usual speed.
When traffic is bad, he drives 30 miles per hour slower and the trip takes one hour longer.
We have to determine,
How far is Jack's father's work from home.
According to the question,
Let, the usual speed = v
And the distance of Jack's father's work from home = y
Jacks father at usual speed taking time, t = 30 minutes = 0.5 hour,
Jacks father speed when traffic is bad, = 30 mph slower.
The formula for speed is defined as = distance ÷ time.
Therefore,
Jacks father drives to work in 30 minutes while driving at his usual speed.
[tex]Speed = \dfrac{distance}{time}\\\\v = \dfrac{y}{0.5}[/tex]
Then,
When traffic is bad, he drives 30 miles per hour slower and the trip takes one hour longer.
[tex]Speed = \dfrac{distance}{time}\\\\v - 30mph = \dfrac{y}{1+0.5}\\\\v = \dfrac{y}{1+0.5} + 30[/tex]
Substitute the value of v from equation 1 to equation 2,
[tex]v = \dfrac{y}{1+0.5} + 30\\\\\dfrac{y}{0.5} = \dfrac{y}{1.5} + 30\\\\\dfrac{y}{0.5} = \dfrac{y +30(1.5)}{1.5}\\\\y (1.5) = 0.5(y +45)\\\\1.5y = 0.5y + 22.5 \\\\1.5y - 0.5y = 22.5\\\\1y = 22.5\\\\y = 22.5 \ miles[/tex]
Hence, The required distance of Jack's father's work from home is y = 22.5miles.

To find the solutions (or, in other words, zeroes) of a quadratic function/equation we use the discriminant (the part that's inside the square root of the quadratic formula, [tex]b^2-4ac[/tex].)
If the discriminant is smaller than 0, there are no zeroes
If the discriminant is equal to 0, there is one zero
If the discriminant is larger than 0, it has two zeroes
The discriminant is commonly denoted as [tex]\Delta[/tex].
Determine whether the triangles are similar. or not.
If similar, state how.
A. similar, AA
B. similar, sss
C. Similar, SAS
D. Not similar
Answer: A
Step-by-step explanation:
Answer A:
Angle H is congruent to angle H. because BC and GI are parrellel, and Angles IGB and CBH are corresponding angles. Triangles HBC and HGI are similar
Yes, the triangles are Similar by SAS similarity criteria the triangles are similar.
What is Similarity?Similar triangles have proportional sides and equal corresponding angles. This similarity can be expressed using the symbol "∼".
We have two Triangles named HBC and HGI
As, per the figure CB || IG
We know, A midsegment is parallel to one side of a triangle and divides the other two sides into congruent halves.
Then, HB / BG = HC / HI
Now, add 1 to both side we get
HB / BG + 1 = HC / HI + 1
(HB + BG) / BG = (HC + HI) / HI
BG / BG = CI / HI
Now, In Triangles HBC and HGI
BG / BG = CI / HI
<H is Common.
Thus, by SAS similarity criteria the triangles are similar.

Find the value of x?
A.45
B.22
C.82
D.56
Answer:
B
x = 22
Step-by-step explanation:
2x + 8 + 3x + 5 = 123 (external angle in a triangle = the two opposite angles)
5x = 123 - 13
5x = 110
x = 22
Answer: B
Step-by-step explanation:
By the Exterior Angle Theorem, we know that the exterior angle is equal to the sum of the two opposite interior angles.
(2x+8)+(3x+5)=123 [combine like terms]
5x+13=123 [subtract both sides by 13]
5x=110 [divide both sides by 5]
x=22
Now, we know that the answer is B.
