If what is the length of DF? ​

The two ways to write the expression k/3+16 are 1/3k + 16 and (k + 48)/3

From the question, the expression is given as

k/3+16

Start by factoring 1/3 out of the first term

So, we have the following expression

1/3k + 16

The above is one of the ways of rewriting the expression

Another way is by taking the LCM

So,we have

k/3+16 = (k + 48)/3

Hence, the equivalent expressions are 1/3k + 16 and (k + 48)/3

The percentage of monthly budget should Jacob allocate for rent is 27.7%.

For the given question;

Jacob's two week earning is $1,350.

Jacob's one week earning will be $1,350/2 = $675.

Considering there are 5 weeks in a months.

Jacob's one month earning will be $675×5 = $3,375.

The total monthly rent = $936.

Let 'x' be the percentage Jacob pay for the rent.

Then,

x% of 3,375 = 936

Simplifying the expression.

3,375x/100 = 936

x = 93,600/3,375

x = 27.7 %

Thus, the percentage of monthly budget should Jacob allocate for rent is 27.7%.

Answer:

8 people

Step-by-step explanation:

117.50 - 5.50 = 112

112 ÷ 14.8 = 7.56756756757, but you round it up to 8, so the answer is 8 people.

SOLUTION

Let's list the values first. These are

48, 65, 60, 45, 54, 64, 70 and 45

Now, we have to arrange these values from the smallest to the largest. Doing this we have

45, 45, 48, 54, 60, 64, 65, 70.

The median will be between the middle items which are 54 and 60. So we will find the median by the following way

Therefore, the Median is 57°F

You have the following equation:

-8(y -7) = 2y + 6

In order to solve for y, proceed as follow:

-8(y -7) = 2y + 6 expand the factor right side

-8y + 56 = 2y + 6 subtract 2y and subtract 56 both sides

-8y - 2y = 6 - 56 simplify

-10y = -50 divide by -10 both sides

y = -50/(-10)

y = 5

Hence, the value of y is 5

The simplified expression of (5x⁶y²)³ is 125[tex]x^{18}y^{6}[/tex] which is expressed using the positive exponents.​

A positive exponent indicates that the base should be multiplied by that many.

For instance, 10 should be multiplied by 10x10x10, or 1000, if the number is 103. The variable x should be multiplied by itself nine times if the variable is x raised to 9.

It is possible to simplify exponents by putting exponent-containing algebraic formulas into a simpler form that prevents further simplification.

The given expression is (5x⁶y²)³

Simplifying it further we get,

(5x⁶y²)³ = 125[tex]x^{18}y^{6}[/tex]

Therefore, the simplified expression of (5x⁶y²)³ is 125[tex]x^{18}y^{6}[/tex] which is expressed using the positive exponents.​

The percentage of New Yorks state teachers that earn between $7000 and $75000 is 13.63%.

Let the salary of the teachers be represented as x.

Mean = $81410

Standard deviation = $9500

In this case, the probability for normal distribution will be used. This is illustrated as P(a < Z < b).

where a = lower number.

b = higher number

Therefore, the probability of earning the amount will be:

P(70000 < X < 75000)

= P[(70000 - 81410/9500) < Z < (75000 - 81410/9500)

= P(-1.20 < Z < -0.67)

Using the z table to look for the value

= 0.8849 - 0.7486

= 0.1363

= 13.63%.

Therefore, the probability is 13.63%.

Answer:

A. Yes, Rectangle A is a scaled copy of rectangle B.

B. Yes, Rectangle B is a scaled copy of rectangle A.

C. No, Rectangle A is not a scaled copy of rectangle C.

Step-by-step explanation:

Rectangle A has dimensions 12x8 and Rectangle B has length 15x10.

We see that sides of A and B are proportional because

[tex]\frac{12}{15} = \frac{8}{10}[/tex]

So we say that since sides are proportional A and B are similar or scaled copy of each other.

Since A is smaller and B is bigger, a is 0.8 scaled copy of B. Similarly B has an enlargement scale factor = 1.25 Rectangle C has 30x15, not proportion with sides of A and B. Hence we find that C is neither a scaled copy of A nor B

Daisy has two measuring jugs, A and B. The volume of each measuring jug will be A and B will be 500 ml and 400 ml.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that, Daisy has two measuring jugs, A and B, that together have a capacity of 900 ml, A jug of water is filled by Daisy. Afterward, she transfers water from jug A into jug B. Following this, jug A has 500 ml of water left.

Total volume = volume in jug A + volume in Jug B

If there are 500 ml of water remaining in jug A.

900 ml = 500 ml + volume in Jug B

volume in Jug B = 900 - 500

volume in Jug B = 400 ml

Thus, Daisy has two measuring jugs, A and B. The volume of each measuring jug will be A and B will be 500 ml and 400 ml.

The sum of the interior angles of a polygon is given by the formula:

Sum = (n - 2)180

where n is the number of sides of the polygon

Since the polygon is a three-sided polygon, n = 3

Sum = (3 - 2)180

Sum = 1 x 180

Sum = 180

Answer:

115°

Step-by-step explanation:

The sum of the three angles in a triangle is always 180°

m∠A + m∠B + m∠C = 180°

m∠B = 180 - m∠A - m∠C

m∠B = 180 - 30 - 35 = 115
