Answer:

the x = 50 degrees, just because the sum of the angles of the triangle = 180 degrees, then the ABD triangle = 50 + 78+52 = 180, also the line AC will have 180 degrees, so the sum 78 + 102 = 180, and the BCD triangle is 102+ 50+28 = 180 and the ABC triangle also is 50+102+28=180

Circle A has a circumference of 25 centimeters.
Circle B's diameter is 3 times as long as circle A's
diameter.
What is the circumference of circle B?

Answers

The circumference of circle B would be; 74.98 cm.

What is the circumference of the circle?

The circumference of the circle that has a radius of r is defined as the product of diameter to the pie value.

The circumference of the circle = 2πr

We have been given that Circle A has a circumference of 25 centimeters.

And Circle B's diameter is 3 times as long as circle A's diameter.

Thus, the Diameter of Circle B = 3 x the Diameter of Circle A

Since The circumference of the circle A = 2πr = 25

2πr = 25

r = 25/  2π

r = 3.98 cm

The Diameter of Circle A = 2 x 3.98 = 7.96 cm

Since Diameter of Circle B = 3 x the Diameter of Circle A

Diameter of Circle B = 3 x 7.96 cm

= 23.88 cm

Radius = 23.88 / 2

Hence, the circumference of circle B =  2πr

= 2 x 22/7 x 23.88 / 2

= 74.98 cm

Find the equation of the linear function represented by the table

y 6 9 12 15
x 1 2 3 4






Answers

9514 1404 393

Answer:

  y = 3x +3

Step-by-step explanation:

The slope of the line can be found using the slope formula:

  m = (y2 -y1)/(x2 -x1)

Using the first two sets of table values, this is ...

  m = (9 -6)/(2 -1) = 3/1 = 3

You can find the point-slope equation using the form ...

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

  y -6 = 3(x -1) . . . . . using the first point in the table

Solving for y gives ...

  y = 3x -3 +6 . . . eliminate parentheses, add 6

  y = 3x +3

fraction word problem

Answers

Answer: 500

Step-by-step explanation: A third of 1,500 is 500, and 2/3 of 1,500 is 1,000. So, 1,500 - 1,000 = 500 liters. Therefore, in order to make the tank full, 500 liters of water are needed.

13
inches, what is the height of the pan?

Answers

Step-by-step explanation:

volume of a rectangular pan = length of the pan × width of the pan × height of the pan

V=l.b.h

234=9.13.h

h=234/9×13

h= 2in.

hope this helps you.

Answer:

2 inches

Step-by-step explanation:

V= 234, L=9, W=13, H=?

V= LxBxH

234= 9x13xH

234= 117H

divide through by 117

234/117 = 117H/117

H= 2inches

Answers

Answer:

C and D

Step-by-step explanation:

Additive inverse is when two numbers add up to zero.

A. Mia walked 5 mi north and then walked 5 mi west.

False. It would be true if the directions are opposite.

B. A scuba diver descends 40 m from sea level and then descends another 10 m.

False. It is - 40 - 10 = -50 m, not zero

C. Gabriella charges $300 on her credit card and then pays the $300 credit card bill.

True. - $300 + $300 = 0

D. A helium atom has 2 positively charged protons and 2 negatively charged electrons.

True. The atom has neutral charge as + 2 + (-2) = 0

Answer:

It is given

4x+3y=24

We can also write it as

3y=24−4x

 y=324−4x

Substituting x=0 in the given equation

 y=324−4(0)

 So we get 

 y=324

 By division 

 y=8 

 Substituting x=3 in the given equation 

 y=324−4(3)

 So we get

 y=312

 BY division 

 y=4

Which one of the following is the same as 72 dekaliters ?


A. 72 dal


B. 72 dI


C. 72 deciliters


D. 72 ml

Answers

Answer:

72 dal

Step-by-step explanation:

short form to dekaliter is dal

Based on the abbreviations for various units of measurements, the best answer here is A. 72 dal

Units of measurements have shorter forms such as:

Liters ⇒ LMilliliter ⇒ MLDekaliters ⇒ DAL

As the short form of dekaliter is dal, the first option must be correct as it is the same as 72 dekaliters albeit in a shortened form.

We can therefore conclude that 72 dal and 72 dekaliters are the same.

im thinking it is J=50(15)^t??? ​

Answers

Answer:

J=15t+50

Step-by-step explanation:

The equation to represent this situation will be in the form J=mt+b where b is the starting value of love units, m represents the "love units" that are multiplied by the number of week, t is the number of weeks, and J represents Jack's love at that specific week.

The equation becomes: J=15t+50

To check, the equation should equal 50 when t=0, 65 when t=1, and 80 when t=2.

Checking t=0:

J=15(0)+50=0+50=50

Checking t=1:

J=15(1)+50=15+50=65

Checking t=2:

J=15(2)+50=30+50=80

The equation J=15t+50 does model the behavior of Jack's love at any week t based on the given data. Note that the equation used was based on slope intercept form (y=mx+b) due to the given data having a linear relationship.

Step-by-step explanation:
