Delta math

Answer:

-46

Step-by-step explanation:

5 (x - 2) - 14x.   x=4

5 (4 - 2) - 14(4)  (distribute)

20 - 10 - 14(4)   (multiply)

20 - 10 - 56    (subtract and solve.)

10 - 56 = -46 - solution

Step-by-step explanation:

The perimeter of a rectangle is the sum of all the sides and the width sides are equal, as well as the two length sides.

For this problem that would mean that two sides are equal to BC and two sides are equal to AB.

Since the perimeter (P)  is equal to 60 , we can write:

P = 2 * BC + 2 * AB

We can substitute the expressions we are given for AB and BC and 60 for the perimeter:

60 =  2 (2z + 3 ) + 2 (3z + 2)

Using the distributive property and combining like terms, we can find the value of the variable , z:

60 = 4z + 6 + 6z + 4

60 = 10z + 10

Subtract 10 from both sides of the equation:

60 - 10 = 10z + 10 -110

50 = 10z

Divide both sides of the equation by 10:

50/10 = 10z/10

5 = z

Since z = 5, then BC is 2z + 3 or 2*5 + 3

BC = 13

Tell me if that's correct!

Answer: B (1/3)

Answer:

Explained below.

Step-by-step explanation:

Categorical variables are those variables that represents certain characteristic or attribute. Such as gender, eye color, age limit and so on.

Numerical variables are variables that assumes numerical values. Such as height, weight, time and so on.

Numerical variables are of two types: Discrete and Continuous.

Discrete variables are those variables that assumes finite whole number values. Such as number of girls in a house, number of children in the nursery and so on.

Continuous variables are those variables that assumes values from a fixed interval. Such as length of screw, amount of payment for donations and so on.

The attributes are classified as follows:

a. Brand of computer purchased by a customer : Categorical

b. State of birth for someone born in the United States : Categorical

c. Price of a textbook : Numerical and Discrete

d. Concentration of a contaminant (micrograms per cubic centimeter) in a water sample : Numerical and Continuous

e. Zip code : Numerical and Discrete

f. Actual weight of coffee in a 1-pound can: Numerical and Continuous

Answer:

5/21

You flip the number 3 which will be "1/3", then you multiply that by 5/7 and you get 5/21

Given expression;

             We are to divide 5/7 by 3;

  Now;

                          [tex]\frac{\frac{5}{7} }{3}[/tex]  

        So;

                    [tex]\frac{5}{7}[/tex]  divided by 3

                 = [tex]\frac{5}{7} x \frac{1}{3}[/tex]

                  = [tex]\frac{5}{21}[/tex]

The solution is     [tex]\frac{5}{21}[/tex]

Answer:

£131.88 or 13188 pence

Step-by-step explanation:

1 unit = 14p

942 units = 942 x 14

942 units = 13188p

£1 = 100p

13188 ÷ 100 = £131.88

Answer:

d

Step-by-step explanation:

when you look at a parallelogram, it could be a rectangle, square, or rhombus. so apply each of these statements to all of these shapes to see if they are true.

a. on a rectangle, not all sides are congruent. cant be that one

b. on a rhombus, not all angles are congruent. cant be that one

c. on a rhombus, the diagonals are not the same length. cant be that one

d. on every parallelogram, the opposite angles are congruent because that is what makes opposite sides parallel

hope this helped :)

The length of each side of the square will be 1 yard.

A square has four equal sides, and four vertices, and is a closed, two-dimensional object. It has parallel sides on either side. A square is also equivalent to a rectangle with equal length and width.

The square's perimeter is four times as long as its side.

For a square with a side length of a unit, we get:

Perimeter of the square = 4a unit

A square has a perimeter of 4 yards. Then the length of each side of the square will be given as,

4 = 4a

a = 1 yard

The length of each side of the square will be 1 yard.

More about the perimeter of the square link is given below.

Answer:

The y-intercept of the equation is 100 and represents the initial studio-use fee.

Step-by-step explanation:

In this equation, our t variable (time) is the equivalent of the x-variable on a graph. This is because it is the variable that we 'change' to see its impact on y. We see how the amount of hours affects the price. So our P variable (price) is the equivalent of y on a graph. The y-intercept is where the line crosses the y-axis on a graph. At this point, x=0.

Since P is our y, and t is our x, to find the y-intercept, we simply need to make t = 0.

P = 50(0) + 100

P = 100

Therefore the y-intercept is 100.

In this context, t represents time, so even though the studio has been used for 0 hours, the price is still 100. This is because the 100 represents the initial studio-use fee, and using it for certain amounts of time adds onto the initial fee of $100. The hourly fee is represented by 50t so it costs $50 more for each hour of use.
