Answer:

b

Step-by-step explanation:

The tangent- secant angle 55° is equal to half the difference of its intercepted arcs, that is

[tex]\frac{1}{2}[/tex] (170 - x) = 55 ( multiply both sides by 2 to clear the fraction )

170 - x = 110 ( subtract 170 from both sides )

- x = - 60 ( multiply both sides by - 1 )

x = 60 → b

Answer:

100

Step-by-step explanation:

first we need to turn the feet into inches

20x12=240

30x12=360

now to get the area of the floor we need to do 360x240=

86,400

now the area of each tile is 24x36=864

now to find out how many tiles fit on the floor we need to do 86,400 divided by 864 which = 100

Answer:

Mean = 3.5

Step-by-step explanation:

The given data is :

4.5,5, 3.5, 2, 2.5

We need to find the mean of the given data.

We know that,

Mean = sum of observations/total no. of observations

Here,

Total no. of observations = 5

Sum of observations = 4.5 + 5+ 3.5+ 2+ 2.5 = 17.5

Mean,

[tex]m=\dfrac{17.5}{5}\\\\m=3.5[/tex]

Hence, the mean of the data set is equal to 3.5.

Answer:

perimeter is 36 and area I think is 72

Step-by-step explanation:

Answer:

60

Step-by-step explanation:

If a school has 100 students doing extra lessons, then;

n(U) =  100

If 36 students were enrolled in mathematics and English. then;

n(MuE) = 36

If  4 students were enrolled in both subjects, then;

n(MnE) = 4

Let  n(MuE)' be those that does not do either subject

hence;

n(U ) = n(MuE) + n(MuE)'

100 = 36 + n(MuE)'

n(MuE)' = 100 - 36

n(MuE)' = 64

Since 4 students were enrolled in both, hence (64-4) i.e 60 does not do either subject.

Answer: 9 tilapia

Step-by-step explanation:

The ratio of 6:20 for tilapia to catfish means that for every six tilapia, there are 20 catfish in the pond.

If there are 30 catfish, use direct proportion to find out the number of tilapia:

6     :      20

x     :       30

Cross multiply:

20x = 180

x = 180 / 20

x = 9 tilapia

Answer:

23°

Step-by-step explanation:

157° = D

D + C = 180°

157 + C = 180

(group like terms)

C = 180 - 157

C= 23°

Answer:

6 Packs

Step-by-step explanation:

Since he needs 46 cookies, he will have to buy 46/8 which is 5.75 packs. But since the packs are sold in whole, not fractions, he buys a ceil approximation of the packs which is 6, because if he buys 5, it will not be enough.

Answer: Linear

Step-by-step explanation: When determining whether the function table represents a linear or exponential relationship, we are checking to see if the rate of change is constant or increasing. If we look at the table, when x increases by 1, y increases by 3. This means that on that interval, the average rate of change is 3/1 = 3. When we increase x by 1 again, we see that y increases by 3 again. This means that the rate of change is constant for the function, so it must be linear.

Answer:

Step-by-step explanation:

What is the probability that a customer ordered

a hot drink given that he or she ordered a large?

So we are looking for the percentage of a hot drink and a Large.

Our list:

Small

Medium Large

Hot

5

48

22

8

12

5

Cold

He can tell there is 10% atleast for hot and 0% for a large

The probability that a customer ordered a hot drink given that he or she ordered a large is 22%

Probability denotes the possibility of the outcome of any random event.

Given that a table of the first 100 customers' orders at a coffee shop.

We need to find the probability that a customer ordered a hot drink given that he or she ordered a large,

= 22 / 100

= 22%

Hence, the probability that a customer ordered a hot drink given that he or she ordered a large is 22%

The Answer Is Not Simmilar

Step-by-step explanation:

This is because you are not given all the info you need, and what you have, the triangle is not similar.

Given:

The expression is:

[tex]\dfrac{2.1\times 10^6}{7\times 10^3}[/tex]

To find:

The simplified form of the given expression in standard form.

Solution:

We have,

[tex]\dfrac{2.1\times 10^6}{7\times 10^3}[/tex]

It can be written as:

[tex]\dfrac{2.1\times 10^6}{7\times 10^3}=\dfrac{21\times 10^5}{7\times 10^3}[/tex]

[tex]\dfrac{2.1\times 10^6}{7\times 10^3}=\dfrac{21}{7}\times \dfrac{10^5}{10^3}[/tex]

[tex]\dfrac{2.1\times 10^6}{7\times 10^3}=3\times 10^{5-3}[/tex]        [tex][\because \dfrac{a^m}{a^n}=a^{m-n}][/tex]

[tex]\dfrac{2.1\times 10^6}{7\times 10^3}=3\times 10^2[/tex]

Given: A triangular prism; 33 meters long, a base of 20 meters, a height of 24 meters. The other two sides of the triangle are each 26 meters

To find: What is the surface area of the triangular prism?

Formula: [tex]A = 12bh[/tex]

Solution: Triangular prisms have their own formula for finding surface area because they have two triangular faces opposite each other. The formula is used to find the area of the top and bases triangular faces, where A = area, b = base, and h = height.

Answer:

m∠WZX = 41°

Step-by-step explanation:

diagonals bisect angles and opposite angles are congruent

therefore, ∠WXY ≅ ∠WZY

∠WZY must equal [360 - 2(68)] ÷ 2 which equals 112°

If ∠WXZ = 71° then so does ∠XZY

Which means that ∠WZX must equal 112-71 which is 41°

===================================================

Explanation:

Refer to the diagram below. I've marked up the figure with various angles to point out the angles we'll be working with.

To make things a bit simpler in terms of notation, and to match up colors with variable letters, I'm going to use the following

Notice how the two red angles I've marked up are alternate interior angles. This works because WX is parallel to ZY. Also notice that the red and blue angles combine to form the angle WZY, which is adjacent to angle XYZ in green.

For any parallelogram, the adjacent angles always add to 180.

(angle WZY) + (angle XYZ) = 180

(blueAngle+redAngle) + (greenAngle) = 180

(B+R) + (G) = 180

(B+71) + (68) = 180

B+139 = 180

B = 180-139

B = 41

The blue angle is 41 degrees, which means angle WZX is 41 degrees

Answer:

Step-by-step explanation:

CP= Rs 400

loss%=12%

let sp be x

SP=CP-loss%*CP

x=400-12/100*400

x=40000-4800/100

x=35200/100

x=352

therefore sp =Rs 352

Answer:

S.P. = ₹352

Step-by-step explanation:

UNITARY METHOD:

If C.P. = ₹100

Then SP = ₹(100-12) = ₹88

If C.P. = ₹1

S.P. = ₹(88/100)

Then, as given: C.P. = Rs 400

S.P. = ₹( 88/100)*400

= ₹352

Therefore, S.P. = ₹352
