Answer:

∠ ABC = 180 - 2x

Step-by-step explanation:

AB and BC are congruent , so the triangle is isosceles with base angles congruent , that is

∠ A = ∠ C = x

the sum of the 3 angles in the triangle = 180° , then

∠ ABC + x + x = 180

∠ ABC + 2x = 180 ( subtract 2x from both sides )

∠ ABC = 180 - 2x

Answer:

3 : 5 also = 0.6

Step-by-step explanation:

Yes, you are able to simplify the ratio into a decimal.

The terms of the expression are: -15h and 5y.

A term of an expression can be a constant, a variable multiplied by a constant, or a variable standing alone.

Given the expression, -9h + 5y - 6h, simplify the expression in order to determine the terms of the expression:

-9h + 5y - 6h

Combine like terms

-9h - 6h + 5y

-15h + 5y

Therefore, the terms of the expression are: -15h and 5y.

The ratio of blue balloons to the total number of balloons a. 1/2.

To find the ratio of blue balloons to the total number of balloons, firstly we need to find the number of blue balloons. Performing addition and subtraction for the same as follows -

Total number of balloons = Number of blue balloons + number of red balloons + number of white balloons

Number of blue balloons = 14 - (3 + 4)

Number of blue balloons = 14 - 7

Number of blue balloons = 7

Ratio = Number of blue balloons to the total number of balloons

Ratio = 7:14

Performing division of both digits by 7

Ratio = 1:2

Hence the ratio of blue balloons to the total number of balloons a. 1/2.

Answer:

x = - 2 ± [tex]\sqrt{70}[/tex]

Step-by-step explanation:

(x + 2)² - 46 = 24 ( add 46 to both sides )

(x + 2)² = 70 ( take square root of both sides )

x + 2 = ± [tex]\sqrt{70}[/tex] ( subtract 2 from both sides )

x = - 2 ± [tex]\sqrt{70}[/tex]

then solutions are

x = - 2 - [tex]\sqrt{70}[/tex] , x = - 2 + [tex]\sqrt{70}[/tex]

Step-by-step explanation:

12 hours will it take to fill the given pool .

we can solve this problem using unitary method ,

10 hours is required to fill the full pool

1 hour is required to fill 1/10th of the pool

30 hours is required to empty the pool

1 hour is required to empty 1/30th of the pool

If two pipes are open then in 1 hour ( 1/10 - 1/30 = 2/30 = 1/15 ) pool will be filled .

The pool is 1/5th filled already as it is mentioned .

So , remaining is ( 1 - 1/5 = 4/5 )

If 1/15th is filled in 1 hour , then 4/5th will be filled in ( 15 × 4/5 ) hours = 12 hours

So, it will take 12 hors to fill the pool .

Explanation:

The rule we use is [tex](\text{x}, \text{y}) \to (-\text{x}, \text{y})[/tex] when reflecting over the vertical y axis.

The x coordinate flips from positive to negative, or vice versa. The y coordinate stays the same. So a point like (-6, 5) reflects over to (6, 5). The x coordinate -6 flipped to +6 or simply 6. The y coordinate stayed at 5.

Use this idea to reflect the other points.

An inequality that represents given scenario is 5 + 2.75x ≤ 21

For given question,

The $21 means that there is a limit to the number of stops she can take using the train.

From given information, we have the following parameters:

Initial Fee = $5

Rate per stop = $2.75

Amount = $21

The inequality that represents the scenario is calculated using:

Initial Fee + Rate × Number of stops ≤ Amount

We use ≤ because the total charges must not exceed the amount.

Let the number of stops be x.

The above formula becomes

5 + 2.75x ≤ 21

Therefore, an inequality that represents given scenario is 5 + 2.75x ≤ 21

The point slope equation for the line that passes through the points (-2, -20) and (9, 79) is 9 x - y - 2 = 0.

We are given the points as:

(- 2 , - 20) and ( 9 , 79)

We will first find the slope:

Slope = m = y₂ - y₁ / x₂ - x₁

m = 79 + 20 / 9 + 2

m = 99 / 11

m = 9

Now, we have to find the point-slope equation for the line that passes through the points (- 2, - 20) and (9, 79).

The point slope equation is:

y - [y₁] = [m](x-[x₁])

Substituting the values, we get that:

y + 20 = 9 ( x + 2 )

y + 20 = 9 x + 18

9 x - y + 18 - 20 = 0

9 x - y - 2 = 0

Therefore, the point slope equation for the line that passes through the points (-2, -20) and (9, 79) is 9 x - y - 2 = 0.

300 Hours will be the Interquartile range for the batteries of type A

In the given data there is a total number of 11 terms for Hours. We have to calculate the median value of Hours by using the formula :

  => Median =  [tex]\frac{n+1}{2}[/tex], and we know that Q2 = Median so Q2 can be calculated by Q2 = [tex]\frac{n+1}{2}[/tex]  => Q2 = 6 => 6th term Will be the Median.

Median = Q2 = 1300 Hours.

Now we have to Calculate Lower Quartile Q1 & Upper Quartile Q3. Since We have our Median 1300 Hours. So, the lower quartile will be :

Q1 = 1100 Hours

and, the Upper Quartile will be Q3 = 1400 Hours.

We have our Upper and Lower Quartiles. We can Calculate Interquartile Range be using the formula Q3 - Q1

   => IQR = Q3 - Q1

Putting values of Q3 and Q1, We get :

  => IQR = 1400 - 1100  => IQR = 300 Hours

Hence, the Interquartile Range IQR is 300 Hours.

Answer: a. 17

b. an=-2.5n+24.5

Step-by-step explanation:

Term number: 3, 4, 5

Terms: 17, 14.5, 12

Term 3 is 17, term 4 is 14.5, and term 5 is 12.

a. The corresponding value to term 3 is 17.

b. Slope formula: m=(y2-y1)/(x2-x1) where x=term number and y=term.

m=(17-14.5)/(3-4)

m=2.5/(-1)

m=-2.5

y=mx+b   ==> Linear equation with slope

12=-2.5(5)+b     ==> substitute a term number and it's corresponding term

12=-12.5+b

b=12+12.5

b=24.5

y=-2.5x+24.5
