Answer:
7
Step-by-step explanation:
Using exact values
(4tan30°)(5sin60°) - 6cos60°
= 20tan30°sin60° - 6cos60°
= 20 × [tex]\frac{1}{\sqrt{3} }[/tex] × [tex]\frac{\sqrt{3} }{2}[/tex] - 6 × [tex]\frac{1}{2}[/tex]
= [tex]\frac{20}{2}[/tex] - 3
= 10 - 3
= 7
Answer:
6.804
Step-by-step explanation:
Given data:
(4tan30°)(5sin60°)-6cos60°
Now it can be calculated as:
4(0.57)×5(0.86)-6(0.5)
2.28×4.3-3

Answer:
median is 2
Step-by-step explanation:
I arranged the numbers from low to greatest and found the "middle" number basically
Answer:
2
Step-by-step explanation:
In order to find the Median of a data set, you must first put the numbers in the data set in order so you'd get:1, 1, 1, 1, 2, 2, 4, 6, 6, 8, 48 Then you would count on each side to the middle and whichever digit is in the middle that is your median.

so x = 40° (corresponding angles QP// RT)
Helpppppppppppppppp meeeee
Answer:
3
Step-by-step explanation:
Both angles are congruent because they are opposite exterior angles.
6x+2=x+17
5x=15
x=3
Answer:
x = 23 °
Step-by-step explanation:
6 x + 2 ° + x + 17 ° = 180 °
combine like terms
6x + x + 2 ° + 17 ° = 180 °
7 x + 19 ° = 180 °
7 x = 180 ° - 19 °
7 x = 161 °
x = 161 ° / 7
x = 23 °
In circle H with mZGHJ = 92°, find the angle measure of minor arc GJ
Answer:
x = 92°
Step-by-step explanation:
The angle measure of the central angle is congruent to the measure of the intercepted arc.
If H is the center of the circle, find mGJI A 117.33 B 222.57 C 242.67 D 256.56
40 POINTS! PLEASE HELP
Answer:
GJI = 242.67
Step-by-step explanation:
A circle is 360 degrees
GI + GJI = 360
The arc length is the same as the angle when it is at the center
117.33 + GJI = 360
GJI = 360 - 117.33
GJI = 242.67
Answer:
GJI = 242.67
Step-by-step explanation:
GI + GJI = 360
117.33 + GJI = 360
GJI = 360 - 117.33
GJI = 242.67

If g(x) = √x and h(x) = x^3 - 1, what is g(h(4))
Answer:
Here, given
g(x) = √x
h(x) = x³-1
For gh(4) , we have to find gh(x), so,
gh(x) = g(x³-1)
=√x³-1 [Note⇒root is both for x³ and 1]
Now,
gh(4) = √4³-1
= 3√7 or 7.9

The triangle is a right triangle, m<c = 50 degrees, angle A + angle c = 90 degrees.
Step-by-step explanation:
Answer:
50°
Step-by-step explanation:
the triangles measurements always add to 180°. the triangle above is a scalene triangle, since none of the angle measurements are the same amount.
Equilateral triangles: All 3 sides are equal
Isoceles triangle: 2 sides are equal
Scalene triangle: No sides are equal
A 3-member committee has to be formed from 2 teachers and 2 parents. How many combinations are possible?
Step-by-step explanation:
the answer is in the above image
The number of combinations possible if a 3-member committee has to be formed from 2 teachers and 2 parents is 4 combinations
Combination and permutationCombinations have to do with selection compared to permutation that has to do with the arrangement.
If a 3-member committee has to be formed from 2 teachers and 2 parents, the total committee is given as:
Total committee members = 2 + 2
Total committee members = 4 committees
If 3-member committee has to be formed from them, the number of ways this can be done is given as:
4C3 = 4!/(4-3)!3!
4C3 = 41/3!
4C3 = 4 ways
Hence the number of combinations possible if a 3-member committee has to be formed from 2 teachers and 2 parents is 4 combinations

Answer:
option B : Upen
Step-by-step explanation:
To find who saves the greatest. Find who spent the least.
That is find the smallest of these fractions.
To find the smallest among the fraction:
Step 1 : make the denominators the same.
Step 2 : to make denominators same find LCM of 8, 4, 3, 6
Step 3: LCM = 24
[tex]\frac{7}{8}\ , \frac{3}{4} \ , \frac{2}{3} \ , \frac{5}{6}[/tex]
[tex]\frac{7 \times 3}{8 \times 3}, \ \frac{3 \times 6}{4 \times 6} , \ \frac{2 \times 8 }{ 3 \times 8} ,\ \frac{5 \times 4}{6 \times 4}\\\\\frac{21}{24}, \ \frac{18}{24}, \ \frac{16}{24}, \ \frac{20}{24}\\\\Arranging\ the \ fractions \ in \ ascending \ order \ to \ find \ the \ least \ spent .\\\\\\frac{16}{24} , \ \frac{18}{24} , \ \frac{20}{24}, \frac{21}{24}[/tex]

What is the angle measure of the third angle of a triangle given the two angles below? 59 degrees and 58 degrees
Answer:
firstly a triangle has angle sum of 180°
Step-by-step explanation:
let all the three angles be x,y and z such that x+y+z =180°
let x= 58° and y =59°
the to calculate for the unknown z angle ;
make z subject of the formula
thus z= 180° -x-y
> z= (180-58-59)°
z= 180-117
z= 63°
Answer:
63
Step-by-step explanation:
59 + 58 = 117
180 - 117 = 63
To find a third angle you will subtract the sum of the two given angles from 180 because all you have to know is that all of the angles in a triangle always add up to 180°.

sum =11+7+2+8=28
MEAN=sum/n=28/4=7
Answer:
The Mean is 7.
Step-by-step explanation:
Mean, or average is when you find a number that is reperesentative of the set as a whole.
To find this we add up all the values and divide it by how many values there are.
11 + 7 + 2 + 8 = 28
28/4 = 7
the furniture store sells dining room tables and chairs. single chairs for particular table sell for 75.00 each. the cost for four chairs when the customer purchases the entire set is 200. what is the percent savings on the 4-chair set rounded to the nearest whole percent?
a.25%
b.33%
c.50%
d.66%
Answer:
B, 33%
Step-by-step explanation:
Let us find the original price of four chairs without the special deal, and compare it with the deal to find the percent savings.
Step 1:
A customer must buy 4 chairs costing $75 each to recieve the deal. Let us multiply 4 by 75 to find the total cost without the deal:
[tex]4*75=\\300[/tex]
Step 2:
We now know the original cost of the 4 chairs, and the price of 4 chairs with a deal. Let us subtract the difference of costs and convert it into a percentage to find percent savings:
[tex]300-200=100\\\frac{100}{300} =\frac{1}{3}[/tex]
[tex]\frac{1}{3}=33[/tex]%
Therefore, B, the percent savings is 33%.

Experts believe the rate of obesity (defined as having a BMI greater than 30) of adults in the United States is approximately 24.5%. A Gallup poll examined the rate of obesity in adults in the United States with a survey of 86,664 randomly sampled U.S. adults. Of the adults surveyed, 23,053 said that they were obese. Select the best description of the sample.
Answer:
86,664 randomly selected U. S Adults
Step-by-step explanation:
The sample is a subset of the population, that is a representative observation which is chosen from a larger population usually used in place of the population due to various reasons which may hamper the use of the entire population on a certain research project. Here, the population of interest is the entire U.S adult.
The subset of the population employed is the 86,664 randomly sampled US adults, this is called the sample as it representative of the population of interest.
