Part B: For the given diagram, use the measure of the special angle relationships created by transversal line b and parallel lines d and e to find the measures of ∠2, ∠3, and ∠4.

Answer:

-13-x(3)

Step-by-step explanation:

Hope this helps :)

The expression in the mathematical form will be 3x + 13.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Negative thirteen decreased by 3 times a number. Then the expression in the mathematical form is given as,

Let x be the number. Then the expression will be

⇒ 3x - (-13)

⇒ 3x + 13

The expression in the mathematical form will be 3x + 13.

Given:

In triangle MNO, angle ONM is a right angle. Angle NOM is 40 degrees and angle LMN is 50 degrees.

To find:

The value of cos(M).

Solution:

In a right angle triangle,

[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]

Draw a diagram using the given information.

In triangle MNO, angle ONM is a right angle so its opposite side MO is the hypotenuse. For vertex M, MN is the base of the triangle. So,

[tex]\cos (M)=\dfrac{MN}{MO}[/tex]

Therefore, the correct option is B.

it is b

51/200.

Step-by-step explanation:

Answer:

51/20 or 2 11/20

Step-by-step explanation:

We know that percentages are fractions out of 100, so, our original fraction would be:

255/100

both of these numbers can be divided by 5, so:

255 ÷ 5 = 51

100 ÷ 5 = 20

51/20

This can also be turned into a mixed number, so:

2 11/20

Step-by-step explanation:

37+27=64

Answer:

A

Step-by-step explanation:

We are given:

[tex]\displaystyle \frac{\sin^2(x)-\sin(x)-2}{\sin(x)-2}[/tex]

To make it simpler and more clear, we can let u = sin(x). So:

[tex]\displaystyle \frac{u^2-u-2}{u-2}[/tex]

Now, it becomes obvious that we can factor, which produces:

[tex]\displaystyle =\frac{(u-2)(u+1)}{u-2}[/tex]

Cancel:

[tex]=u+1[/tex]

And substituting back:

[tex]=\sin(x)+1[/tex]

Hence, our answer is A.

Answer:

one solution

Step-by-step explanation:

The number of solutions 2x+3y=4, x-y=3, 3x+5y=6 is​

Solving two of the equations simultaneously

2x+3y=4,  ... 1 *1

x-y=3 ... 2 * 2

_________

2x+3y = 4

2x-2y = 6

subtract

3y+2y = 4+6

5y = 10

y = 10/5

y = 2

Recall that x - y = 3

x - 2 = 3

x = 3+2

x = 5

Hence the solution has just one solution

Answer:

c. In 2 seconds, the commuter train travels 120 feet.

Step-by-step explanation:

Given

The attached graph

Required

What does x-coordinate of 2 represents

Represent this coordinate with (x,y)

From the graph:

[tex]x = 2[/tex] when [tex]y = 120[/tex]

Note that:

x = time and y = distance

So:

[tex](x,y) = (2,120)[/tex]

Which means:

At 2 seconds, the train has travelled a distance of 120ft

From the list of options, (c) is correct

step 1. the sale is 20% off; that means times 0.8.

step 2. the additional coupon is 10% off of the sale price; that means times 0.9.

step 3. so the final price is (0.8)(0.9) times the retail price

step 4. (0.8)(0.9) = 0.72 or a 28% discount and not 30%.

Answer:

8.7, 8.9, 9.0

Step-by-step explanation:

Answer:

8.7, 8.9, & 9.1

Step-by-step explanation:

The decimal places go up by tens like all other numbers. Therefore, 8.7, 8.9, and 9.1 are all in between 8.6 and 9.2

Step-by-step explanation: Remember that "times" mean multiply.

So reading the problem from left to right, we have n times 5,

that's n multiplied by 5 or 5n, is means equals, 24.

So we have 5n = 24.

We want to solve our equation for n so we want to get

n by itself on the left side of the equation.

Since n is being multiplied by 5, we need to divide both sides

of the equation by 5 and we have n = 24/5.

Don't be nervous to check your answer back in

the original equation even if it is a fraction.

Answer:

x=59deg

Step-by-step explanation:

We will use tangent to find the angle because we do not know the length of the hypotenuse.

Tan(x)=opp/adj

Tan(x)=30/18

Tan(x)~59

So the last option is correct. 59deg

Standardized tests: In a particular year, the mean score on the ACT test was 19.3 and the standard deviation was 5.3. The mean score on the SAT mathematics test was 532 and the standard deviation was 128. The distributions of both scores were approximately bell-shaped. Round the answers to at least two decimal places. Part: 0/4 Part 1 of 4 (a) Find the z-score for an ACT score of 26. The Z-score for an ACT score of 26 is

Answer:

1.26

Step-by-step explanation:

Given that:

For ACT:

Mean score, m = 19.3

Standard deviation, s = 5.3

Zscore for ACT score of 26;

Using the Zscore formula :

(x - mean) / standard deviation

x = 26

Zscore :

(26 - 19.3) / 5.3

= 6.7 / 5.3

= 1.2641509

= 1.26

Answer:

3490 coins

Step-by-step explanation:

Given data

Total coins= 2792 coins

Half of the coins are on display

that is 50% are on display

=2792/2

=1396

let the coins bought be x

40% of x= 1396

40/100*x= 1396

0.4x= 1396

x=  1396/0.4

x=3490

Hence 3490 coins were bought
