Answer:

111°

Explanation:

Based on the F angles theorem, ∠ABH = ∠BFE = 69°,

and based on BE ≅ BF, ∠BEF must also be 69°.

∠DEB is supplementary to ∠BEF, so

∠DEB = 180 - 69 = 111.

Answer:

5x10^6

Step-by-step explanation:

30000/0.006=5000000

5000000=5x10 to the power of 6

5x10^6

Answer:

Step-by-step explanation:

From the information given, you can write the following equations:

x+y=300 (1)

5x+8y=300*7

5x+8y=2100(2)

First, you can isolate x in (1):

x=300-y (3)

Now, you can replace (3) in (2):

5(300-y)+8y=2100

1500-5y+8y=2100

3y=2100-1500

y=600/3

y=200

Then, you can replace the value of y in (3) to find x:

x=300-200

x=100

According to this, the answer is that he should use 100 pounds of dried pineapple and 200 pounds of dried apricots.

Answer:

Ruby = x = 22 hours

Isaac = y = 16 hours

Svetlana = 88 hours

Step-by-step explanation:

Let the number of hours worked be represented as:

Ruby = x

Isaac = y

Svetlana = z

Total number of hours worked =

x + y + z = 126 hours........ Equation 1

Ruby worked 6 hours more than Isaac,

x = y + 6..... Equation 2

Svetlana worked 4 times as many hours as Ruby

z = 4 × x

z = 4x

z = 4(y + 6)

z = 4y + 24....... Equation 3

Substituting y + 6 for x and 4y + 24 for z in Equation 1

x + y + z = 126 hours........ Equation 1

y + 6 + y + 4y + 24 = 126

Collect like terms

y + y + 4y + 6 + 24 = 126

6y + 30 = 126

6y = 126 - 30

6y = 96

Divide both sides by 6

6y/6 = 96/6

y = 16

Since y represents the number of hours Isaac worked, Isaac worked for 16 hours

Substitute 16 for y in equation 2

x = y + 6

x = 16 + 6

x = 22

Since x represents the number of hours Ruby worked, Ruby worked for 22 hours

Substitute 16 for y in equation 3

z = 4y + 24

z = 4 × 16 + 24

z = 64 + 24

z = 88

Since z represents the number of hours Svetlana worked, Svetlana worked for 88 hours

Therefore:

Ruby worked for 22 hours

Isaac worked for 16 hours

Svetlana worked for 88 hours

Answer:

35 they are alternate interior angles.

Step-by-step explanation:

Angle is alternate interior with angle 2 so it would be same measure in most cases. They are congruent so it would be the same measure equaling 35 degrees.

Given points

Use slope formula to find the slope

Slope is -4

Answer:

slope is -4

Step-by-step explanation:

Find slope which is also referred to as m:

m = (y₂ - y₁) / (X₂ - X₁)

   = (-7 - 5) / (1 - (-2)

   = -12 / 3

m = -4

Not asked in question but if you want to find equation for the line:

Find b using any one of the two provided coordinates. Let's use (-2, 5).

y = mx + b

5 = -4(-2) + b

5 = 8 + b

b = -3

Use m and b to make equation.

y = mx + b

y = -4x - 3

Answer:

Answer:

  (x, y, z) = (8, 5, -9)

Step-by-step explanation:

Using the first equation, we can write an expression for z:

  z = 12 -2x -y

We can substitute this into the other two equations. (Before we do that, we'll divide the second equation by 5.)

  x + y + (12 -2x -y) = 4   ⇒   -x +12 = 4

  x -4y +(12 -2x -y) = -21   ⇒   -x -5y +12 = -21

__

The first of these gives us a value for x:

  8 = x . . . . add x-4 to both sides

Using this in the second equation of these, we have ...

  -8 -5y +12 = -21

  -5y = -25

  y = 5

Then the value of z is ...

  z = 12 -2(8) -5

  z = -9

The solution to the system is (x, y, z) = (8, 5, -9).

Step-by-step explanation:

-2(x + 3) = 8

-2x - 6 = 8

-2x = 8 + 6

-2x = 14

x = -14/2

x = -7

Answer: X= -1/2, X= -5/6

Step-by-step explanation:

0=12x^2+16x+5

Move all terms to the left:

0-(12x^2+16x+5)=0

Add all the numbers together, and all the variables

-(12x^2+16x+5)=0

Get rid of parenthesis

-12x^2-16x-5=0

a = -12; b = -16; c = -5;

Δ = b2-4ac

Δ = -162-4·(-12)·(-5)

Δ = 16

The delta value is higher than zero, so the equation has two solutions

Use following formulas to calculate:

x1=−b−Δ√2ax2=−b+Δ√2a

Δ−−√=16−−√=4

-> x1=−b−Δ√2a=−(−16)−42∗−12=12−24=−1/2

-> x2=−b+Δ√2a=−(−16)+42∗−12=20−24=−5/6

Answer:

Addison scored a better score on the test.

Step-by-step explanation:

Elaine's score can be found by dividing 19 by 24, which yields a result of 0.7916, which means her score is a 79 out of 100 (79%). Her score can also be found by doing 100/24 = 4.16666 repeating and multiplying that by 19, which also yields 79.6. Hope this helps!
