If the measure B is 40 degrees, what measures can A and C be? Select the three correct answers.

Answer:

Step-by-step explanation:

Solution:

Rewriting input as fractions if necessary:

9/10, 1/4

For the denominators (10, 4) the least common multiple (LCM) is 20.

LCM(10, 4)

Therefore, the least common denominator (LCD) is 20.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

9/10 = 9/10 × 2/2 = 18/20

1/4 = 1/4 × 5/5 = 5/20

Answer:

The third one

Step-by-step explanation:

The graphs in the reversed shape of a cup are the graphs of quadratic equations whose coefficient of

x^2 is negative.

So, the answer must be either the first or the third.

It can be seen that when x= -4, y becomes 5.

Substituting the value of x, the third equation gives the value 5.

So, the answer is the third one.

Answer:

f⁻¹(x) = eˣ / 3

Step-by-step explanation:

f(x) = In(3x)

y = In(3x)

swap x and y: x = In(3y)

solve y: eˣ = 3y

y = eˣ / 3

f⁻¹(x) = eˣ / 3

Answer:

(- 1, - 2 )

Step-by-step explanation:

Given the 2 equations

y = - 2x - 4 → (1)

y = 4x + 2 → (2)

Substitute y = 4x + 2 into (1)

4x + 2 = - 2x - 4 ( add 2x to both sides )

6x + 2 = - 4 ( subtract 2 from both sides )

6x = - 6 ( divide both sides by 6 )

x = - 1

Substitute x = - 1 into either of the 2 equations and solve for y

Substituting into (2)

y = 4(- 1) + 2 = - 4 + 2 = - 2

solution is (- 1, - 2 )

Option (2)

Step-by-step explanation:

Amount of apples in a box = [tex]2\frac{3}{4}[/tex] pounds

                                            = [tex]\frac{11}{4}[/tex] pounds

Apples used by Sage = [tex]\frac{1}{5}th[/tex] Part of the total amount

                                    = [tex]\frac{1}{5}[/tex]th part of the apples in the box

                                    = [tex]\frac{1}{5}\times \frac{11}{4}[/tex]

                                    = [tex]\frac{11}{20}[/tex] pounds

Therefore, Sage used [tex]\frac{11}{20}[/tex] pounds of the apples.

Option (2) will be the answer.

Answer:

11 1/4

Step-by-step explanation:

Multiply this by three, 3, 6, 9.

3/4, 1 2/4, 2 1/4.

2 + 9 = 11.

11= 1/4 = 11 1/4

Answer:

Max drank 11 1/4 cups of milk today.

Explanation:

Convert the mixed number (3 3/4) to a fraction.  

Then your equation becomes:

15/4 x 3/1 (since he tripled the cups of milk he drank you multiply by 3 which as a fraction is 3/1)

Next:

15/4 x 3/1= 11 1/4!

Hope this helps :)

Answer:

Step-by-step explanation:

Rebecca's car insurance been reduced by 18%

A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction.

Given that, Last year, Rebecca's car insurance cost her £2043. This year it only cost her £1675.26.

Percentage decrease = (Final value - initial value) / initial value × 100

Final value = £1675.26

Initial value = £2043

Percentage decrease = (2043 - 1675.26) / 2043 × 100

= 367.74 / 2043 × 100

= 0.18 × 100

= 18 %

Hence, Rebecca's car insurance been reduced by 18%

Answer:

60 pounds of meat

Step-by-step explanation:

Number of lions = 4

Pounds of meat consumed = 7 pounds each

Number of cubs = 8

Pounds e meat consumed = 4 pounds each

Amount of meat consumed each day by the lions = 4 × 7 + 8 × 4

Multiply first

= 28 + 32

= 60 pounds of meat

The lions consume 60 pounds of meat each day.

Answer:

  f(x) = 2(x -3)² +5

Step-by-step explanation:

For vertex (h, k) and scale factor 'a', the vertex form is ...

  f(x) = a(x -h)² +k

We can fill in the values of h and k from your vertex, and use the values of the extra point to find 'a'.

  55 = a(-2 -3)² +5

  50 = 25a . . . . . . . . subtract 5

  a = 2 . . . . . . . . . . . divide by 25

So, the function is ...

  f(x) = 2(x -3)² +5

__

In standard form, that will be ...

  f(x) = 2x² -12x +23

Answer:

A) 45-(+15)+25-(-5) = 35

B) -30-(-14)-(-4)= -12

The inside diameter would be the outside diameter minus 2 of the wall thicknesses.

4 9/32 - (2 x 7/32)

Simplify:

4 9/32 - 14/32

Because 14/32 is larger than 9/32 change one of the hole numbers to a fraction: 1 = 32/32

rewrite 4 9/32 as 3 41/32

Now subtract:

3 41/32 - 14/32 = 3 27/32 inside diameter.

Answer:

E = 58

F = 32

G = 90

Step-by-step explanation:

3x + 31 + 5x -13 + 90 = 180

3x + 31 + 5x -13 = 90

8x = 90 - 31 + 13

8x = 72

x = 72 / 8

x = 9

E = 3(9) + 31 = 27+31 = 58

F = 5(9)-13 = 45 - 13 = 32

G = 90

Answer:

8(m⁶ - 8n¹²p¹⁵)

Step-by-step explanation:

Given:

8m⁶ - 64n¹²p¹⁵

The only part that we can factor out is in the coefficients.  Because both terms use different variables, they can not be factored.  However, both terms are divisible by eight, so we can say it equals:

8(m⁶ - 8n¹²p¹⁵)

And that is all the factoring that can be done.
