Given JM = 27, ML = 16, JL = 46, NK = 15, m∠KLM = 48°, m∠JKM = 78°, and m∠MJL = 22°To findm∠JKLSolution

JKLM is a parallelogram and therefore has equal opposite angles:

∠JKL = ∠JML and ∠KJM = ∠KLM

Sum of all four is 360°:

2m∠JKL + 2m∠KLM = 360°m∠JKL + m∠KLM = 180°m∠JKL + 48° = 180°m∠JKL = 180° - 48°m ∠JKL = 132°

log base root3 of (x-y) = 2

log base 4 of x - log base x of y = 7/6

Answers

Answer:

Step-by-step explanation:

SYSTEM:

log base root3 of (x-y) = 2 .... 1

log base 4 of x - log base x of y =7/6...2

From equation 1:

x-y = (√3)²

x - y = 3 ..... 3

From equation 2:

log base 4 of x - log base x of y =7/6

-log base x of 4 - log base x of y = 7/6

log base x of 4^-1 - log base x of y = 7/6

log base x of (1/4) - log base x of y = 7/6

According to law of logarithm

Log base x {1/4 ÷ y} = 7/6

x^7/6 = 1/4y .... 2

From 1, y = x-3

x^7/6 =1/4(x-3)

x^7/6 = 1/(4x-12)

x^7/6(4x-12) = 1

Write an equation for the line parallel to the given line that contains C.
C(2,8); y = - 2x + 1
y =

Answers

Okay!

Whenever a line is parallel to another, that means they ALWAYS have the same slope!

So the slope of our new line is -2 as well !

Now let's use point C (2, 8) to find the y-intercept!

This is easy! All we need to do is plug the point in our new equation!

Remember that in point C, 2 = x and 8 = y

Time to plug in all these numbers in y = mx + b

8 = -2 (2) + y intercept

→ the 8 is in the y's place

→the -2 is in the slope place

→2 is in the x place

Now we solve for the y-intercept using basic math!

8 = -2(2) + y-intercept

8 = -4 + y-intercept

8 + 4 = y-intercept

We did it! We found the y-intercept

The y-intercept is 12!

Now let's create our final equation ...

y = -2x + 12

so whats the question.

Which ordered pair is a solution of the equation y+1=3(x-4)

Answers

Step-by-step explanation:

When x = 4 and y = -1,

(-1) + 1 = 3(4 - 4) = 0.

Hence (4, -1) is an ordered pair.

When x = 5 and y = 2,

(2) + 1 = 3(5 - 4) = 3.

Hence (5, 2) is an ordered pair.

Therefore the answer is C.

Cory made 4,500g of candy He saved 1 kg to eat later. He divided the rest of the candy over 7 bowls to serve at his party.
How many grams of candy did Cory serve in each bowl?

Answers

Answer:

In each bowl, Cory put 500 grams of candy.

Step-by-step explanation:

You would do 4,500 - 1 (since he save a kilogram for himself), which would equal 3,500.

Then, you would do 3,500 divided by 7 (since there are 7 bowls and he wants to split the remaining candy evenly), which would equal 500.

Answer:

Cory served 500 grams of candy in each bowl.

Step-by-step explanation:

4,500 = 4.50 kilograms

4.50kg - 1.00kg = 3.50kg

3.50kg ÷ 7kg = 0.50kg

0.50kg = 500g

What is the check digit, d, for the credit card number shown below?
6424 9813 2720 008d

Answers

Answer:

A.1

Step-by-step explanation:

I did a check digit calculator and it said that this would be the check digit

The check digit is 1.

Step-by-step explanation:

The check digit on credit is calculated by the following step:

Mark each digit odd and even from the right side.Now multiply each digit at an even place with '2'.And if the number after multiplication is double-digit then add both the digit to obtain a single digit.Now add all the digits obtained in the previous step along with digits at odd places.To this sum obtained check by adding what digit it becomes next multiple of '10'.And that digit will be our check digit.

Given:

The creditcard number: 6424 9813 2720 008d

To find :

Check digit,d

Solution:

6424 9813 2720 008d

Marking odd and even places from right side:

(e:even place,o:odd place)

e,o,e,o e,o,e,o e,o,e,o e,o,e,o

6 4 2 4 9 8 1 3 2 7 2 0 0 0 8 d

Multipling every even place digit with '2'.

12,4,18,2,4,4,0,16

If two digit number then add both digits to have single digit

12,4,18,2,4,4,0,16 → 1+2,4,1+8,2,4,4,0,1+6 → 3,4,9,2,4,4,0,7

Now adding all the digits obtained in prevoius step with digits at odd place:

(3+4+9+2+4+4+0+7)+(4+4+8+3+7+0+0)= 59

The next multiply of 10 can be obtained by adding 1 to '59' that is 60. So, the check digit will be'1'.

59+1 = 60

(60 is a multiple of the number '10'.)

The check digit is 1.

Answers

Answer: $70.49

Step-by-step explanation:

Cost of gasoline = $2.75 per gallon

Cost of diesel fuel = $3.02 per gallon.

Since Gabriel needs to purchase 15.2 gallons of gasoline for his truck, the amount spent on gasoline will be:

= 15.2 × $2.75

= $41.80

Since he needs to spend 9.5 gallons of diesel fuel for his tractor, the amount spent on diesel fuel will be:

= 9.5 × $3.02

= $28.69

Total cost spent will be:

= $41.80 + $28.69

= $70.49

(X+y,y+3)=(6,2y)

Equating corresponding elements,we get,

X+y=6------(1)

y+3=2y-----(2)

solving equation (2),

y-2y=-3

Left on together the cold and hot water faucets of a certain bathtub takes 6 minutes to fill the tub. If it takes the hot water faucet 15 minutes to fill the tub by itself , how long will it take the cold water faucet to fill the tub on its own ?

Answers

Answer:

10 minutes

Step-by-step explanation:

We have

1/ hot water faucet + 1/ cold water faucet = 1/6

= 1/15 + 1/c = 1/6

1/c = 1/6 - 1/15

Lowest Common Denominator

= 30

Hence:

1/c = 5 - 2/30

1/c = 3/30

1/c = 1/10

Cross Multiply

c = 10 minutes

Hence, it will take the cold water faucet 10 minutes to fill the tub on its own
