i need help with this one plz! (marking BRAINLIST) :)
Answers
Answer: (a) = 110 degrees, (b) = 8
If I understand the picture correctly, (a) wants you to find the angle K. It first shows us that both J to K, and L to K are equal in length of 11, thus there is no deviation in angle 35 degrees with L (so they both equal each other). Therefore, the angle K will equal 180 degrees subtracted by the sum of J and L, which is 110 degrees.
For (b), it appears that all the angles have the same singular mark at the edges, so all sides will equal 8.

Abby sells beauty products. She has a monthly salary of $1000. She also earns 1%
commission on the first $8000 of her sales for the month and 4% commission on
sales over $8000. What is Abby's gross income for the month if her sales were $12
500
Answers
Answer: $1260
Step-by-step explanation:
Based on the information given, Abby's gross income for the month if her sales were $12500 will be:
= $1000 + (1% × $8000) + [4% × ($12500 - $8000)]
= $1000 + (0.01 × $8000) + (0.04 × $4500)
= $1000 + $80 + $180
= $1260
Her gross income is $1260

what are the y and x intercepts?
Answers
Answer:
(18/5, 0) is the x intercept
(0,-2) is the y intercept
Step-by-step explanation:
-5x+9y = -18
Set y = 0 and solve for x to find the x intercept
-5x +0 = -18
Divide each side by -5
x = -18/-5
x = 18/5
(18/5, 0) is the x intercept
Set x = 0 and solve for y to find the y intercept
0 +9y = -18
Divide each side by 9
y = -18/9
y = -2
(0,-2) is the y intercept
Answer:
x- intercept is 18/5
y- intercept is -2

Find the answer to b and check if a is correct and explain plsss
Answers
Answer:
a. 105.84 cm²
b. 136 cm²
Step-by-step explanation:
a. The prism is a cube
Surface area of the cube = 6a²
a = 4.2 cm
Plug in the value
Surface area = 6*4.2²
Surface area = 105.84 cm²
b. The prism is a triangular prism
Surface area of triangular prism = bh + L(s1 + s2 + s3)
b = 6 ft
h = 4 ft
L = 7 ft
s1 = 5 ft
s2 = 5 ft
s3 = 6 ft
Surface area = 6*4 + 7(5 + 5 + 6)
Surface area = 24 +7(16)
Surface area = 24 + 112
Surface area = 136 cm²
Find cot 0, sec 0, and cos 0, where is the angle shown in the figure. Give exact values, not decimals approximations.
Answers
Answer:
Cot 0 = undefined
Sec0 = cos0 = 1
Step-by-step explanation:
According to trig identity
Cot theta = 1/sin theta
Sec theta = 1/cos theta
Hence
Cot 0 = 1/tan0
Cot 0 = 1/0
Since a/0 is undefined, hence cot 0 will be undefined
Sec 0 = 1/cos 0
Sec0 = 1/1 = 1
Cos 0 = 1

12.) The FAA has to periodically revise their rules regarding weight estimates that vary by
season. Airlines currently use an estimate for the weight of an adult male passenger of 190 lbs.
in the summer that assumes
he carries sixteen pounds of baggage and has five pounds of
clothing. According to your textbook, assume that men (not clothed nor carrying baggage) have
weights that are normally distributed with a mean of 188.6 lbs. and a standard deviation of 38.9
lbs.
a.) If one adult male is randomly selected and is assumed to be also carrying 21 lbs. due to
clothing and baggage, find the probability that the total weight is greater than 190 lbs.
b.) What total weight would separate the lower 20% of men carrying 21 lbs. of clothing and
baggage from the top 80%?
Answers
Answer:
a) 0.4856 = 48.56% probability that the total weight is greater than 190 lbs.
b) A total weight of 155.9 lbs.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score 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 p-value, we get the probability that the value of the measure is greater than X.
Mean of 188.6 lbs. and a standard deviation of 38.9 lbs.
This means that [tex]\mu = 188.6, \sigma = 38.9[/etx]
21 lbs of baggage are taken into consideration in this estimate.
a.) If one adult male is randomly selected and is assumed to be also carrying 21 lbs. due to clothing and baggage, find the probability that the total weight is greater than 190 lbs.
This is 1 subtracted by the the p-value of Z = 190. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{190 - 188.6}{38.9}[/tex]
[tex]Z = 0.036[/tex]
[tex]Z = 0.036[/tex] has a p-value of 0.5144.
1 - 0.5144 = 0.4856.
0.4856 = 48.56% probability that the total weight is greater than 190 lbs.
b.) What total weight would separate the lower 20% of men carrying 21 lbs. of clothing and baggage from the top 80%?
This is the 20th percentile, which is X when Z has a p-value of 0.2, so X when Z = -0.84.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-0.84 = \frac{X - 188.6}{38.9}[/tex]
[tex]X - 188.6 = -0.84*38.9[/tex]
[tex]X = 155.9[/tex]
A total weight of 155.9 lbs.
The function f(x) = x² +9 and the other function P is given by P(x) = f(x) - 34 ÷x + 5 find P (5 )
Answers
Answer:
32.2
Step-by-step explanation:
Given :
f(x) = x² +9
P(x) = f(x) - 34 ÷ x + 5
P(5) =?
Substitute 5 for X on P(x)
P(5) = f(5) - 34 ÷ x + 5
f(5) = 5² + 9 = 25 + 9 = 34
P(5) = 34 - 34 ÷ 5 + 5
According to PEMDAS
-34 ÷ 5 = - 6.8
P(5) = 34 - 6.8 + 5
P(5) = 34 - 1.8
P(5) = 32.2

How many inches are there in 3 yards?
A. 108 in.
B. 96 in.
C. 72 in.
D. 48 in.
Answers
Answer:
108
Step-by-step explanation:
3 yards equal 9 feet and 1 foot equals 12 inches so that means do 12 x 9 and you get 108
The correct option is A.
How to convert feet to yards?Feet ÷ 3 = 1 yards. yard is 3 feet long, so all you have to do is divide the number of feet by 3 to get the number of yards for your measurement
We know that,
1 feet is equal to 12 inches.
1 feet = 12 inches.
1 yard = 36 inches.
3 yards = 36 × 3 = 108 inches.
3 yards = 108 inches.
Therefore, 108 inches are there in 3 yards.
