can someone please help me with this question.?...​

Answer:

Step-by-step explanation:

Given:

A shelf is built on a wall. The angles of the triangle are given as (x + 3)°, (2x - 18)° and 90°

We need to determine the value of x.

Value of x:

By triangle sum property, the angles in a triangle always add up to 180°

Thus, we have;

Simplifying, we get;

Subtracting both sides by 75, we get;

Dividing both sides of the equation by 3, we get;

Thus, the value of x is 35.

Answer:

b corresponding angles

Answer:

[tex]x + 7 = 18[/tex]

Step-by-step explanation:

[tex]2(x + 7) = 36[/tex]

[tex]x + 7 = 18[/tex]

Answer:

70°

Step-by-step explanation:

[tex] m\widehat {BC} = 90\degree - m\widehat {CD} [/tex]

[tex] m\widehat {BC} = 90\degree -20\degree [/tex]

[tex] m\widehat {BC} = 70\degree [/tex]

Answer:

B. 3

Step-by-step explanation:

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

Explanation:

Angles 1 and 3 are vertical angles. Note how line t and line r intersect to form an X shape. Angle 1 and angle 3 are opposite angles in this X configuration, which is what makes them vertical angles. Vertical angles are always congruent.

Angle 1 is congruent to angle 2 if and only if both angles were 90 degrees (note the angles are supplementary). Otherwise, they aren't congruent. That allows us to rule out choice A. Choice C is ruled out for the exact same reason.

Answer:

= 1.5 × 10 with the power of 10

Step-by-step explanation:

The total number of games a girl play against a boy is 25, the number of games a girl plays against a boy is 10, the fraction of the games are boy-versus-boy is 2/9, and 1/5 fraction of all games at the tournament Anita plays the game.

We have given that,

Of the 10 kids in a chess club, 5 are left-handed and 5 are right-handed.

A permutation can be defined as the number of ways a set can be arranged, order matters but in combination, the order does not matter.

We have 5 girls and 5 boys in a chess club:

There are a total of 5×5 games girls play against a boy.

= 5×5

= 25

The number of games a girl play against another.

It is a combination problem so the total number of games:

= 10

A fraction of the games are boy-versus-boy:

The number games boy-versus-boy = 10

The number games Boy vs Boy & Girl vs Girl & Boy vs Girl

= 10+10+25

=  45

So the fraction = 10/45 ⇒ 2/9

If Anita is one of the club members then Anita will have to play against 9 people at the tournament.

Total number of games = 45

Then the fraction = 9/45 ⇒ 1/5

Thus, the total number of games a girl play against a boy is 25, the number of games a girl plays against a boy is 10, the fraction of the games are boy-versus-boy is 2/9, and 1/5 fraction of all games at the tournament Anita play the game.

Answer:

x = 30

Step-by-step explanation:

correct me if i am wrong but i think you have to

a.) change the denominator's to be the same :

ten is a common denominator therefore you times the second expression by two ( x/5 becomes 2x/10 )

b.) put the formula back together :

3x/10 + 2x/10 = 15

5x/10 = 15

5x = 150

x = 30

Answer:

A. 4/12, C. 1/3

Step-by-step explanation:

2/6 can be divided by 3. Therefore, the fraction is 1/3.

A. 4/12 can be divided by 4. This means the fraction will be 1/3. Because 1/3 is equal to 1/3, this option is correct.

B. 1/2 cannot be simplified. Because 1/3 is not equal to 1/2, this option is not correct.

C. 1/3 cannot be simplified. Because 1/3 is equal to 1/3, this option is correct.

D. 3/8 cannot be simplified. Because 3/8 is not equal to 1/3, this option is not correct.

Answer:

A

Step-by-step explanation:

∠4 and ∠8 are corresponding angles

corresponding angles are congruent ( equal to each other )

so if ∠4 = 100° then ∠8 also equals 100°

Answer:

A

Step-by-step explanation:

8 is equal to 4(100) because it is corresponding angle, corresponding angle are equal to each other...If 4 is 100 then 8 will be 100

Answer: 4 bags

Step-by-step explanation:

2 cups  =  16 ounces

So  using a proportion

16 / 8   =  x  /  60          where  x  is the number of ounces we need to buy

cross-multiply

16 * 60   =  8 * x

960   = 8 x

960 / 8   = x  =   120    ounces

The  number of  bags  we  need   =    ceiling  [ 120/32 ]    = 4 bags

(order them in numerical value, least to greatest)

take off one number from each side until you have one number left

Answer: 78

Step-by-step explanation: The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average. Write all of the numbers and cross out a even amount of numbers on both sides. Image 1 shows your problem. If your problem had another number, you solve it differently. Check image 2.

Answer:

a)  [tex]P(10)=0.2061[/tex]

b)  [tex]P(9\ or\ 12)=0.3172[/tex]

c)  [tex]P(X>10)=0.51545[/tex]

Step-by-step explanation:

From the question we are told that:

Probability of Same day resolution [tex]P=70\%=>0.7[/tex]

Probability of Another day resolution [tex]Q=1-P=>30%=>0.3[/tex]

Sample size [tex]n=15[/tex]

a)

Generally the equation for Probability 10 of the problems can be resolved today is mathematically given by

Since

 [tex]P(X)=^{n}C_{x}*p^{x}*Q^{n-x}[/tex]

 [tex]P(10)=^{15}C_{10}*p^{10}*Q^{15-10}[/tex]

 [tex]P(10)=\frac{15!}{10!(15-10)!*0.70^{10}*0.30^5}[/tex]

 [tex]P(10)=0.2061[/tex]

b)

Generally the equation for Probability 9 or 12 of the problems can be resolved today is mathematically given by

 [tex]P(9)=\frac{15!}{9!(15-9)!*0.70^{9}*0.30^6}[/tex]

 [tex]P(9)=5005*2.942*10^{-5}[/tex]

 [tex]P(9)=0.1472[/tex]

OR

 [tex]P(12)=\frac{15!}{12!(15-12)!*0.70^{12}*0.30^3}[/tex]

 [tex]P(12)=455*3.737*10^{-4}[/tex]

 [tex]P(12)=0.17[/tex]

Therefore Probability 9 or 12 of the problems can be resolved today is

 [tex]P(9\ or\ 12)=P(9)+P(12)[/tex]

 [tex]P(9\ or\ 12)=0.1472+0.17[/tex]

 [tex]P(9\ or\ 12)=0.3172[/tex]

c)Generally the equation for probability more than 10 of the problems can be resolved today is mathematically given by

 [tex]P(X>10)=P(11)+P(12)+P(13)+P(15)[/tex]

Where

 [tex]P(11)=\frac{15!}{11!(15-11)!*0.70^{11}*0.30^4}[/tex]

 [tex]P(11)=0.2186[/tex]

 [tex]P(13)=\frac{15!}{13!(15-13)!*0.70^{13}*0.30^2}[/tex]

 [tex]P(13)=0.0916[/tex]

 [tex]P(14)=\frac{15!}{14!(15-14)!*0.70^{14}*0.30^1}[/tex]

 [tex]P(14)=0.0305[/tex]

 [tex]P(15)=\frac{15!}{15!(15-15)!*0.70^{15}*0.30^0}[/tex]

 [tex]P(15)=0.00475[/tex]

Therefore

 [tex]P(X>10)=0.2186+0.0916+0.0305+0.00475+0.17[/tex]

 [tex]P(X>10)=0.51545[/tex]

21 = (x - 5) + (2x - 1)

21 = x - 5 + 2x - 1

21 = 3x -6

3x = 21 + 6

3x = 27

x = 9

Answer:

y = 5x -23

Step-by-step explanation:

Alright, for this, we need the slope and the y intercept. First, the slope.

So to find the slope, find any two points that the line goes over first. For example, the dotted point (5,2). Now for the other one, (4,-3) can be used.

Look for when the line is crossing over the points of the square graph, as this will help you with the next part.

For the next part, to find the slope, this is going to see how much the line has done up/down for how much we move forward or backwards on the line. With this, the equation:

y2-y1 / x2-x1 can be used, with the 2s and 1s being just to show that there are 2 separate points being used for it.

Next, plug it in with what's known:

2-(-3) / 5-4

5 / -1

Slope is 5.

Now, the y intercept needs to be found. To get this, we need the y value for where the line passes over where the x value is 0.

By knowing that the slope is 5, we can walk backwards to the y intercept to get this value. With this, for every number in x walked back, it will go down 5 y values:

5, 2 (Do -1, -5)

4, -3 (Do -1, -5)

3, -8 (Do -1,-5)

2, -13 (Do -1,-5)

1, -18 (Do -1,-5)

0, -23 (All done)

The y intercept is now found, along with the slope. Now these values can be both be plugged into the slope intercept equation, y=mx+b, where m is for the slope and b is where the y intercept goes.

y = 5x -23

Answer:

let the width be x

so 3x × x = 48

=> 3x^2 = 48

=> x^2 = 16

=> x = 4

So the length = 4×3 = 12 inches

breadth= 4 inches

Answer:

Step-by-step explanation:

x = -1:  2(3)^(-1) = 2(1/3) = 2/3

x = 0:  2(3)^0 = 2(1) = 2

x = 1:    2(3)^1 = 6

x = 2   2(3)^2 = 18
