If mBE=119 and mBKE=93, find mUH.
Answer:
arc UH = 67°
Step-by-step explanation:
the measure of a chord- chord angle is half the sum of the measures of the arcs intercepted by the angle and its vertical angle , then
[tex]\frac{1}{2}[/tex] ( BE + UH ) = ∠ BKE , that is
[tex]\frac{1}{2}[/tex] (119 + UH ) = 93° ( multiply both sides by 2 to clear the fraction )
119° + UH = 186° ( subtract 119° from both sides )
UH = 67°
Answer:
Step-by-step explanation:
∠HKU = ∠BKE {Vertically opposite angles}
∠HKU = 93°
Angles fromed by insecting chords equals half the sum of intercepting arcs.
[tex]\sf \angle HKU =\dfrac{1}{2}(arc \ HU + arc \ BE) \\\\ 93^ \circ = \dfrac{1}{2}(arc \ HU + 119)[/tex]
93 *2 = arc HU + 119
186 = arc HU + 119
186 - 119 = arc HU
arc HU = 67°

A researcher is interested in whether blind Braille readers could be taught to read faster using the same techniques as sighted readers. He has blind adults complete a reading speed test before and after a six-week speed-reading course. In the beginning of the study, a randomly selected group of 121 blind Braille readers scored an average of 261 words per minute on the reading speed test. Since the sample size is larger than 30, the researcher can assume that the sampling distribution of MD is normal. He plans to use a repeated-measures t test. The researcher identifies the null and alternative hypotheses as:

This table gives the value of an investment for the first 14 years after the initial investment was made. The data can be modeled using an exponential function.
Years 2 4 6 8 10 12 14
Investment value $692 $952 $1,304 $1,813 $2,316 $3,256 $4,718
Based on the data, which amount is closest to the value of the investment 18 years after the initial investment? PLS HURRY I NEED THIS ANSWERED NOW, WILL GIVE 95 POINTS
Answer:
General form of an exponential equation: [tex]y=ab^x[/tex]
where:
a is the initial valueb is the growth factorx is the independent variabley is the dependent variableLet x = years
Let y = investment value
Use (2, 692) and (4, 952) to find a and b of the exponential equation:
[tex]ab^2=692[/tex]
[tex]ab^4=952[/tex]
[tex]\implies \dfrac{ab^4}{ab^2}=\dfrac{952}{692}[/tex]
[tex]\implies b^2=\dfrac{238}{173}[/tex]
[tex]\implies b=\sqrt{\dfrac{238}{173}}=1.17\:\textsf{(nearest hundredth)}[/tex]
[tex]\implies ab^2=a\left(\dfrac{238}{173}\right)=692[/tex]
[tex]\implies a=\left(\dfrac{59858}{119}\right)=503.01\:\textsf{(nearest hundredth)}[/tex]
Therefore, the exponential equation is:
[tex]y=503.01(1.17)^x[/tex]
18 years after the initial investment is when [tex]x=18[/tex]:
[tex]\implies 503.01(1.17)^{18}=8490[/tex]
Therefore, the amount closest to the value of the investment 18 years after the initial investment is $8490
(If you use the exact values for a and b rather than the rounded values, the amount is $8879)

Find the volume will give brainliest to whoever answers correctly
Answer:
Vol = 252 cubic ft
Step-by-step explanation:
Consider the bottom and top of the shape separately. Calculate the volumes and add them together.
Bottom of the shape is a prism. Volume of a prism:
V =
Base Area•Height
The base is a triangle. Use Area of a triangle formula:
A = 1/2b•h
A = 1/2(7)(6)
A = 21
Use 21 for Base Area for both parts of the volume calculation.
Vol of prism, continued:
V = 21•9
V = 189
Volume of a pyramid (top)
V = 1/3•BaseArea•Ht
=1/3(21)(9)
=63
Total Volume=
189 + 63
= 252 cubic ft

How does the volume of a cylinder with a radius of 3 units and a height of 12 units compare to the volume of a rectangular prism with dimensions 16 units x 16 units x 9 units?
a. The volume of the cylinder is greater than the the volume of the prism
b. The volume of the cylinder is smaller than the volume of the prism.
C. The volume of the cylinder is the same as the volume of the prism
d.You cannot compare the volumes of different shapes
Answer:
The volume of the cylinder is greater than the volume of the prism.
Step-by-step explanation:
The Volume of a cylinder is given as:
= πr²h
Therefore, the volume of a cylinder with a radius of 3 units and a height of 12 units will be:
= πr²h
=3.14 × 3² × 12
=339.12
The volume of a rectangular prism with dimensions 3 units x 3 units x 12 units will be:
= Length × Width × Height
Based on the calculation, the volume of the cylinder is greater than the volume of the prism.
Answer:
B: The volume of the cylinder is smaller than the volume of the prism.
Step-by-step explanation:
In order to find the volume of the cylinder, we would use to formula [tex]\pi r^{2} h[/tex]. Substitute the given measures of the cylinder to get [tex]\pi[/tex]·3²·12. The simplified and calculated form would be 108 units cubed.
Now, we find the volume of the rectangular prism, which is [tex]l[/tex]·[tex]w[/tex]·[tex]h[/tex], or 16*16*9. This means the volume is 2304 units cubed.
Therefore, since 2304 un³>108 un³, answer choice b would be correct.
Of the 4 people attending a lecture, 2 have hazel eyes.
What is the probability that a randomly selected person will have hazel eyes?
Write your answer as a fraction or whole number.
Answer: 50%
Step-by-step explanation:
Because 2 of four is half, that that the probability is a 50% chance.
Answer:
1/2
Step-by-step explanation:
Think of this like a pizza or pie:
If there are four slices and two represent hazel eyes, how many slices are "hazel eyes?" It would be 2 of 4, or 2/4.
Because this is a fraction and it can be simplified, it would be 1/2.
So there is a 50% chance that the randomly selected person of the four people will have hazel eyes.

The a seer to the more expensive rug is; D: the green rug is $11.01 more expensive than the white rug.
How to calculate mark up and mark down?We are told that;
Current cost of Green rug = $54.50
Current cost of White rug = $31.85
Now the store wants to mark down the green rug by 12%. Thus;
New price of green rug = (100% - 12%) × 54.5
New price of green rug = $47.96
Now the store wants to mark up the white rug by 16%. Thus;
New price of white rug = (100% + 16%) × 31.85
New price of green rug = $36.95
Difference in New prices = $47.96 - $36.95
Difference in New prices = $11.01
