In parallelogram ABCD, the measure of angle A=3x and the measure of angle B =x+10. What is the measure of angle D?

Answers

Answer 1

Answer: 52.5

Step-by-step explanation: 2(3x+10)+2(x+10)=360 because all the sides of a rhombus equal 360 and alternate sides are equal

8x+20=360

-20=-20

8x/8=340/8

x=42.5

x+10. 42.5+10=52.5

D=52.5

Answer 2

The measure of ∠D in parallelogram ABCD is 52.5°.

What is a parallelogram?

A parallelogram is a 2D figure in which opposite sides are equal.

We know in a parallelogram sum of the adjacent angles is 180° and opposite angles are equal.

∴ In a parallelogram, ABCD ∠A = ∠C and ∠B = ∠D and we also know that sum of all the interior angles of a parallelogram is 360°.

∴ ∠A + ∠B + ∠C + ∠D = 360°.

2∠A + 2∠B = 360°.

2(3x) + 2(x+10) = 360°.

6x + 2x + 20° = 360°.

8x = 340°.

x = 42.5°.

Given, ∠B = ∠D = x + 10° = 42.5° + 10° = 52.5°.

what is the y and x intercept of 15x + 20y =1800?

Answers

You can do this by doing 1800 / 15 which is 120 and 1800 / 20 which is 90
Which means that the x intercept is 120 and the y intercept is 90.

For the y-intercept equation, the x will always be 0. And vice versa.

20y = 1800
Divide by 20 on both sides

y = 90

15x = 1800
Divide 15 on both sides

x = 120

Zoe makes a total of $72.85 selling cookies and cupcakes at a bake sale. If she sells 17 cupcakes for $3.25 each, how many cookies does she sell at $1.60 each? Make sure to explain how you got your answer.

Answers

Answer:

46. or 45.5 if not rounded

Step-by-step explanation:

We know she makes $72.85 at selling cookies if she sales 17 cupcakes for $3.25 she'll make $55.25 but were trying to find how many she sales with $1.60 so $72.85 divided by 1.60 is 45.5 and if not then it's 46. rounded.

As part of the performance bonus in a certain company, an employee will earn a 1 % increase every month. Ricka earns P 20 000 every month. How much will she earn after a year?

Answers

Answer:

FV= $22,536.5

Step-by-step explanation:

Giving the following information:

Growth rate (i)= 1% monthly

Present value (PV)= $20,000

Number of periods= 12 months

To calculate how much will the employee earn after a year, we need to use the following formula:

Sorry this got to you super late. At least others looking for the answer can find it.

The proof by S A S congruence rule is given below.

Given from fig, JK || LM.

And JK = LM

Since JK is parallel to LM and JN is a transversal so the angle made on the same side of JN are corresponding angles which are equal to each other.

So, angle KJL = angle MLN........equation 1

Also given L is the midpoint of JN so, JL = NL.....equation 2

Now, in triangle JLK and triangle LNM

JK = LM (given)

angle KJL = angle MLN (from 1)

JL = NL (from 2)

So by S A S congruence rule, triangle JLK conguent triangle LNM proved.

Answer: -4c+12

all real numbers

Step-by-step explanation:

6) 28-(3c+4) =2 (c+6)+c

When there is a - in front of an expression in parentheses , change the sign of each term of the expression.

28-3c-4=2(c+6)+c

Distribute 2 through the parentheses

28-3c-4=2c+12+c

Now we do the same thing only different way

2(c+6)

Multiply each term in the parentheses by 2

2c+2×6

Multiply the numbers

2c+12

_____________

28-3c-4=2c+12+c

subtract the numbers

24-3c=2c+12+c

Collect like terms

24-3c=3c+12

It's the same thing only different way ok

2c+c

If a term doesn't have a coefficient , it is considered that the coefficient is 1.

2c+1c

Collect like terms by adding their coefficients

(2+1)c

Add the numbers

________

24-3c=3c+12

Move variable to the left hand side and change its sign

24-3c-3c=12

Move constant to the right by adding its opposite to both sides

-3c-3c+24-24=12-24

eliminate the opposites

-3c-3c=12-24

Collect like terms

-6c=12-24

Calculate the difference

-6c=-12

so the same thing only different way ok

12-24

Keep the sign of the number with the larger absolute value and subtract the smaller absolute value from the larger.

-(24-12)

Subtract the numbers

-12

__________

-6c=-12

divide both sides of the equation by -6

-6c÷(-6)=-12÷(-6)

Any expression divided by itself equals 1

c=-12÷(-6)

Dividing two negatives equals a positive

(-)÷(-)=(+)

c=12÷6

Which equation has a graph that is parallel to the graph of 2x − y = −1?

A. 2x + y = 8
B. y = −1/2x + 3
C. y − 1 = 2(x − 3)
D. y = −2x − 1

Answers

Answer:

Step-by-step explanation:

So from the first graphs equation is

2x-y=-1

therefore if we made y the subject of the formula, the equation would be

2x+1=y , this is also the same as y=2x+1

from this, the equation is clearly in the form y=mx+c so we can get the gradient

The gradient of graph one would be 2

The perpendicular gradient would be the negative reciprocal of graph one's gradient which would be -1/2

Now we look at our options and see which one has the gradient as -1/2

Using linear function concepts, it is found that the equation parallel to 2x - y = -1 is given by:

C. y − 1 = 2(x − 3)

The equation of a line has the following format:

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

I n which m is the slope.If two lines are parallel, they have the same slope.

The equation of the line given is:

[tex]2x - y = -1[/tex]

[tex]y = 2x + 1[/tex]

Which has slope [tex]m = 2[/tex]

If we look at option C:

[tex]y - 1 = 2(x - 3)[/tex]

[tex]y = 2x - 6 + 1[/tex]

[tex]y = 2x - 5[/tex]

It also has slope of [tex]m = 2[/tex], the same as the line given, thus, they are parallel.
