Answer:

34 degrees

Step-by-step explanation:

If ABD = 64, and CBD is 30, we can use PWP( Part Whole Postulate)

Step 1.CBD + ABC = ABD

Step 2. Substitute

30 + ABC = 64

Step 3. Isolate ABC

34 = ABC

ABC is 34 degrees

9514 1404 393

Answer:

  34°

Step-by-step explanation:

It should be fairly intuitive that the two smaller angles add to give the value of the larger one. (Even if it's not, the angle sum theorem tells you this is true.)

  ∠ABC + ∠CBD = ∠ABD

  ∠ABC + 30° = 64°

  ∠ABC = 34° . . . . . . . . . subtract 30° from both sides of the equation

There are not statements. But...

If she studies more her grade is better.

The more she studies, the more her grade goes up.

The less she studies, the more her score goes down.

Just some guesses for you. Match up with your statements.

Hannah is observing he following relation {G} [tex]$\alpha[/tex] {1/T}

Function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function

Expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators

Equation : A mathematical equation is used to equate two expressions.

Given is that Hannah finds that the amount of time she spends studying for her history tests affects her grade on the test.

Let the amount of time she spends studying for her history tests is denoted by the variable {T}.

Let her grade is denoted by the variable {G}. So, we can write -

{G} [tex]$\alpha[/tex] {1/T}.

Therefore, Hannah is observing he following relation -

{G} [tex]$\alpha[/tex] {1/T}.

Answer:

[-7, 6]

Step-by-step explanation:

The range is the y values that the equation/line covers.

The line's lowest point is -7 and the line's highest point is 6. The value is defined at both -7 and 10 since there is a closed circle in both locations- so we use brackets.

solid circle on -1.95 and go right

Answer:

a. h(t) = 5t + 10

b. 70

c. h(5) = 35 means that in 5 seconds, it will be 35 feet above ground.

Step-by-step explanation:

a. Since the elevator is already 10 feet of the ground, u have to add that in the equation. And since it's 5 feet per second, 5 will be a multiplier so:

h(t) = 5t + 10

b. We have the equation already and in the equation it said that "t" represents the seconds so just replace 1 with 12:

h(12) = 5(12) + 10

h(12) = 60 + 10

h(12) = 70

c. Refer to b that we just did if u will, "t" represents seconds so h(t) becoming h(5) means 5 seconds. So h(5) = 35 means that in 5 seconds, it will be 35 feet above ground.

Answer:

y=x-4

Step-by-step explanation:

We can see that x is always 4 times larger than y or y is always 4 times less than x

This means that y=x-4

Answer:

The Answer Is "y = x - 4"

Answer: 50 words per minute

Step-by-step explanation:

250 words per 5 minutes DIVIDE BOTH NUMBERS BY 5

50 words per 1 minute

Answer:

It's a proportion:

500=2.5

50=x

2.5×50:500=0.25kg

50 sheets weigh 0.25 kg

Step-by-step explanation:

Answer:

0.25

Step-by-step explanation:

the weight of a sheet = 2.5kg/500

the weight of a sheet = 0.005kg

the weight of 50 sheets = 0.005 * 50

the weight of 50 sheets = 0.25kg

since it's a uniform rate

500 sheets = 2.5kg

50 sheets = xkg

then you cross multiply.Having:

500*x = 2.5 * 50

500x = 125

then x = 125/500

x = 0.25

Answer:

1/8 or 0.125

Answer:

[tex]2x+y\geq 20[/tex]

Step-by-step explanation:

Given that total points required to make the playoffs = 20 points

As there is 2 points for a win,

so points earned for x win = 2x

Similarly, as there is 1 point for a tie.

so points earned for y ties = 1[tex]\times[/tex] y= y

Total points earned for x win and y ties = 2x+y

As the team makes the playoff so the total points of the team must be equal to or greater than 20 points (i.e the minimum points to make the playoff), so

[tex]2x+y\geq 20[/tex]

Hence, the required equation is [tex]2x+y\geq 20[/tex].

Answer:

Rounded to the nearest whole number is 25

Answer:

x = 2

Step-by-step explanation:

(Square both sides)

20 - 8x = x^2

(Solve 20 - 8x = x^2)

x = 2 , x = 10

x = 10 is false, so the answer is x = 2.

Answer:

x=2

Step-by-step explanation:

√20-8x=x

2√5-2x=x (by simplfing redical expression)

4(5-2x)=x^2 (square both side)

20-8x=x^2

20-8x-x^2=0

-x^2-8x+20=0

x^2+8x-20=0

x=2

Note:There is a another answer x=-10 But it's wouldn't fit out with this equation

Answer:

Option (D)

Step-by-step explanation:

Sue made a quilt pattern comprising 16 congruent isosceles right triangles.

She cuts the pieces of triangle having each leg = 6 inches

By applying Pythagoras theorem in isosceles triangle,

(Hypotenuse)² = (leg 1)² + (leg 2)²

x² = 6² + 6²

x² = 72

x = √72

x = 8.485

x ≈ 8.5

Option (D) will be the correct option

Answer:

The answer is D. (8.5)

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

Answer:

Please check the explanation.

Step-by-step explanation:

Given the equation

[tex]-x + 2y = 4[/tex]

a) writing the equation in the slope-intercept form

We know that the slope-intercept form of the equation of the line is

[tex]y=mx+b[/tex]

where m is the slope of the line

so writing the equation in the slope-intercept form

[tex]-x + 2y = 4[/tex]

[tex]2y=4+x[/tex]

[tex]y=\frac{1}{2}x+2[/tex]

b) Identify the slope of the line represented in part a

As the equation in slope-intercept form is

[tex]y=\frac{1}{2}x+2[/tex]

Here,

m = slope = 1/2     ∵ [tex]y=mx+b[/tex]

c) What is the slope of the line perpendicular to the line in steps a and b

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so

As the slope = 1/2

So the slope of the perpendicular line will be: -2

d. Write the equation of the perpendicular line in slope-intercept form.

Therefore, the point-slope form of the equation of the perpendicular line that goes through (-2,1) is:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = -2 and the point (-2,1)

[tex]\:y-1=-2\left(x-\left(-2\right)\right)[/tex]

[tex]y-1=-2\left(x+2\right)[/tex]

Add 1 to both sides

[tex]y-1+1=-2\left(x+2\right)+1[/tex]

[tex]y=-2x-3[/tex]
