I'm unsure how to do this question,, could someone help?

Answer:

75%

Step-by-step explanation:

Madison got 18 problems right and there's 24 problems in total. The question asks for the percentage of the problems that she answered correctly. So, put the number of questions that she got right and the total number of questions into a fraction and simplify.

18/24=3/4

3/4ths= 75%

25 if im not wrong......

Answer:

5/8

Answer:

  1. 2x +2y = 310; x -y = 55

  2. y = 50, x = 105

Step-by-step explanation:

Let the numbers be represented by x and y. Double the numbers would give 2x and 2y. We're told the sum of the doubled numbers is 310, so one equation is ...

  2x + 2y = 310

The difference of the numbers is (x-y). We're told that difference is 55, so the other equation is ...

  x - y = 55

__

We can divide the first equation by 2, and subtract the second.

  1/2(2x +2y) -(x -y) = 1/2(310) -(55)

  2y = 100 . . . . . . . simplify

  y = 50 . . . . . . . . . divide by 2

  x -50 = 55   ⇒   x = 105 . . . . use the second equation to find x

The two numbers are 105 and 55.

The slope is 1/4 and 2 is the y intercept

Answer:

it's b

Step-by-step explanation:

the reason it's b is because conduction happens when something hot comes in contact with something cold which heats the cold thing up and cooling the hot thing eventually they will both be room temperature

Answer:

17/20

Step-by-step explanation:

[tex]\frac{25}{100} + \frac{6}{10}[/tex]

to solve this multiply both fractions by 100

(25 + 60) / 100 = 85/100

we need to find the lowest common multiple

Both the numerator and denominator can be divided by 5 = 17/20

Answer:

C

Step-by-step explanation:

this is because this is the only value that will yield 40 when you have 0 as a x value

40(1/4) to the 0

which is 40*1=40

if my answer helps please mark as brainliest.

Answer:

C. 40(0.25)^x

Step-by-step explanation:

Given that it is an inverse function we can see that when x = 0, y = 40 and when x = 1, y = 10. Then you look for which function fits the criteria, given that only 40(0.25)^x does it is C.

Given:

The probability that Jamil will be late for work is 0.2.

To find:

The probability that Jamil will not be late for work.

Solution:

We have,

P(Jamil will be late) = 0.2

We know that,

P(Jamil will not be late) = 1 - P(Jamil will be late)

                                       = 1 - 0.2

                                       = 0.8

Therefore, the probability that Jamil will not be late for work is 0.8.

Answer:

126 :)

Step-by-step explanation:

Answer:

Step-by-step explanation:

first find angle ∠U,

As sum of angle in triangle = 180°

Now ∠U+∠V+∠W=180°

88°+38°+∠U=180°

∠U=54°

Now total horizontal line = 180°

∠NUV=180°-54°=126°

Answer:

15x^7y^11

Step-by-step explanation:

First, multiply the coefficients 5 and 3 together.  We get:

15x^4y^3 * x^3y^8

Please note that it's mandatory to use " ^ " to indicate exponentiation.

Since x^4*x^3 = x^7, we next obtain:

15x^7y^11

Answer:

Step-by-step explanation:

1. 1 Simplify  2+6-4d to  -4d+8.

7 ( -4d + 8)

therefor, the answer is, 7( -4d + 8)

Answer:

7(2 + 6 - 4d) = 7(8 - 4d) = (56 - 28d)

Step-by-step explanation:

There is no possible answer to this equation but this is the most accurate equation, since you cant go any further, this is your simplified form.

1. 13.8

2. 34.32

4. 7.2

5. 211.12

3. 28.05

Answer:

you substitute x for 4

Step-by-step explanation:

so its f(x) and f(4) so you use 4 for x so you would solve f(x)=3(4)+2

Answer:

13.75

Step-by-step explanation:

The expected value of the hourly wage is the sum of the probabilities (percentage of time spent on each job) multiplied by the payoff (money earned) from each possible occurrence (job):

(0.6 × 11) + (0.25 × 19) + (0.15 × 16) = $13.75.

Answer:

Now how did I find the translation rule ( x - 1, y + 4). Well basically, I did was

8 - 9 = -1

-4 - (-8) = 4

Now if you use the same translation rule for (9, -8), you will get :-

(x - 1, y + 4)

( 9 - 1, -8 + 4)

( 8, -4)

I get the same answer that is given in the problem.

Hope this helps, thank you !!

Answer:

72.24

Step-by-step explanation:

Price for each camera = 14

Number of camera = 2dozen = 12 x 2 = 24

Total cp = 24 x 14 = 336

~~~~~~~~~~~~~~

Price for each camera=  10.99

Number of cams = 24

Total sp = 10.99 x 24 = 263.76

Loss = 336 - 263.76  = 72.24

Answer:

C= 2pi-r

Răspuns:

292,50

Explicație pas cu pas:

Dobânda totală% = (1% + 16%) = 17% = 17/100 = 0,17

Suma principală depusă, P = 250

Suma totală, A după 1 an poate fi calculată astfel:

A = P (1 + rt)

Unde ; r = rata dobânzii; t = timp

A = 250 (1 + (0,17 * 1))

A = 250 (1,17)

A = 292,5
