Use The Given Information To Find The Value Of X. Then, Find The Measure Of Angle ADC.

Answers

Answer 1

Answer:

60degrees

Step-by-step explanation

To get the angle x, you must first know that the sum of angle at a point is 360degrees. Hence;

x + <ADB + <CDB  = 360

x +150 + 150 = 360

x+ 300 = 360

x = 360 - 300

x = 60

Hence the value of x is 60degrees

Answer:

x = 2

Step-by-step explanation:

Let's solve your equation step-by-step.

4 ( x − 1 ) = 2 ( 6 − 2 x )

Step 1: Simplify both sides of the equation.

4 ( x − 1 ) = 2 ( 6 − 2 x )

( 4 ) ( x ) + ( 4 ) ( − 1 ) = ( 2 ) ( 6 ) + ( 2 ) ( − 2 x ) (Distribute)

4 x + − 4 = 1 2 + − 4 x

4 x − 4 = − 4 x + 12

Step 2: Add 4 x to both sides.

4 x − 4 + 4 x = − 4 x + 12 + 4 x

8 x − 4 = 12

Step 3: Add 4 to both sides.

8 x −  4 + 4 = 12 + 4

8 x = 16

Step 4: Divide both sides by 8.

8 x / 8 = 16 / 8

x = 2

Given line 1, with coordinates (-7,-3) and (4,7), and line
2 with coordinates (7,-7) and (-3, 4), find the slope of line 2

Answers

Answer:

-11/10 (fraction) or -1.1 (decimal)

Step-by-step explanation:

The slope formula is m=(y2-y1)/(x2-x1)

x1 = 7

x2 = -3

y1 = -7

y2 = 4

So, it’s: (4 - (-7))/(-3-7)

= (4+7)/(-3-7)

= (11)/(-10)

= -11/10 or -1.1

Sue has 4lbs 6oz of apples. Her younger brothers ate some and now she has 2lbs and 10oz how many lbs and oz of apples did they eat

Answers

Answer: 1 lbs 12 oz

Step-by-step explanation:

First and foremost, we should note that 16 ounces = 1 pound

Sue has 4lbs 6oz of apples. This in ounces will be:

= (4 × 16) + 6

= 64 + 6

= 70 ounces

Her younger brothers ate some and now she has 2lbs and 10oz. The ounces of apples left will be:

= (2 × 16) + 10

= 32 + 10

= 42 ounces

Therefore, the amount they ate will be:

= 70 ounces - 42 ounces

= 28 ounces

Since 16 ounces = 1 pounds

= 1 pounds 12 ounces

= 1 lbs 12 oz

Which account has the greater​ principal? Select the correct answer below and fill in the answer boxes to complete your choice.

Answers

Answer:

Step-by-step explanation:

I=Prt

11.25=A(0.03)(15/12)

11.25=A(0.0375)

A=11.25/(0.0375)

A=$300

25=B(0.05)(15/12)

25=B(0.0625)

B=25/(0.0625)

B=$400

So account B has the greater principal.

d) 318.5

Answers

Answer:

b i think

Step-by-step explanation: dont yell just tell me if i got it wrong if i did srry

The rate of change when x increases and the first difference equal to 45.5 is 6.5. Then the correct option is A.

What is the slope?

The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.

The slope is given as

[tex]\rm Slope = \dfrac{Rise \ or \ fall}{Run}[/tex]

If x increases by 7 in each row of a table of values and the first differences are all equal to 45.5. Then the rate of change will be given by the slope.

[tex]\rm \\Slope = \dfrac{45.5}{7} = 6.5[/tex]

The rate of change is 6.5.

Answers

Answer:

Monthly payment= $440.71

Step-by-step explanation:

Giving the following information:

Mothly interest rate (i)= 0.025/12= 0.00208

Number of periods (n)= 12*10= 120 months

Future Value (FV)= $60,000

To calculate the monthly payment, we need to use the following formula:

Monthly payment= (FV*i) / [(1+i)^(n) - 1]

Monthly payment= (60,000*0.00208) / [(1.00208^120) - 1]

Monthly payment= $440.71
