Rectangle Area: lw

Put the measurements into the expression

(7)(5)

7•5 = 35

Triangle Area: 1/2bh

1/2(7)(2)

1/2(14)

Answer:

  A = 8x³ +4x² -4x

Step-by-step explanation:

Put the given values into the area formula and simplify.

  [tex]A=\dfrac{1}{2}h(b_1+b_2)\\\\A=\dfrac{1}{2}(4x)((x^2+2)+(3x^2+2x-4))\\\\A=(2x)(4x^2+2x-2)\\\\\boxed{A=8x^3+4x^2-4x}[/tex]

Answer:

4(6x+1)=124

Step-by-step explanation:

To find the area of a rectangle, you use this formula: area= length *width

so you input the length (6x+1) TIMES the width (4)

if u earned $150 and had a rate of 3% if u add thise up u get $450 plus the 5 years you will have $950 i thonk that this is the right answer i dont really know

Answer:

70

Step-by-step explanation: Triangle angle sum theorem states the interior angles of a triangle sum to 180 degrees. We know one angle is 40 degrees and the two remaining angles are equal in measure.

Since angle J and angle L are equal in measure we can substitute 2x for angles J and L into the equation.

40 + 2x = 180. Subtract 40 from both sides.

2x = 140. Divide both sides by 2.

X = 70

Answer:

c. 9 units

Step-by-step explanation:

Answer:

y=-x/3+2

Step-by-step explanation:

If you graph out 3x-y-7=0, you will get a line that goes through the points (0, -7), and about (2.3, 0). If you graph out y=x/3+2, you have to make sure that this line forms a 90 degree angle on the previous line, thus making this line perpendicular to the previous line.

50

Answer:

-1/3

Step-by-step explanation:

The common difference is how much it goes up by with each new number, so you can see that each time it goes down by 1/3. This means that the common difference is -1/3.

Answer:

412.53 inches

or

11.45916 yards

Step-by-step explanation:

Answer: 11.46yd

Step-by-step explanation:

The formula for the circumference is dπ.

So using the formula you would have to do the inverse so 36/π=11.46 (2 decimal places)

d = number of dimes

n = number of nickels

The jar contains a total of 107 coins, so

d + n = 107

Each dime is worth $0.10 and each nickel is worth $0.05, and the jar contains a total value of $6.70, so

0.10d + 0.05n = 6.70

Multiply both sides of the second equation by 100 to eliminate the decimal points:

10d + 5n = 670

Multiply both sides of the first equation by -5:

-5d - 5n = -535

Add the corresponding sides of these two equations to eliminate n and solve for d :

(10d + 5n) + (-5d - 5n) = 670 + (-535)

(10 - 5)d + (5 - 5)n = 670 - 535

5d = 135

d = 135/5 = 27

Then

n = 107 - d = 80

so the jar contains 27 dimes and 80 nickels.

Answer: b. randomly select people from all residents of the apartment building.

Step-by-step explanation:

This issue at hand concerns all residents of the building so the apartment manager should randomly select people to participate in the survey from the entire population of all the residents of the apartment building.

Selecting only those who have children would not be representative of the whole population as there will be people with less or more children than 5 and some would not have children. Option C and D are wrong because only current residents should be included.

Answer:

18.85

Step-by-step explanation:

Answer:

D. 23

Step-by-step explanation:

5y = [360 - (65 x 2)] / 2

5y = [360 - 130] / 2

5y = 230 / 2

5y = 115

y = 23

Hope that helps!

Answer:

suppose length is x

breadth is y

now,

      x.y=18

      2(x+y)= 18

x= 3

y=6

Step-by-step explanation:

Weekly pay = amount per hour x number of hours:

24 x 11.63 = 279.12

Annual salary = weekly pay x 52 weeks:

279.12 x 52 = 14,514.24

Answer:

17 grams

Step-by-step explanation:

21grams-4=17grams

Answer:

17 grams

Step-by-step explanation:

Since the starting mass was 21 and the change was -4, you would do 21-4, which gives you 17 grams (or the final mass).

Answer:

7/10

Step-by-step explana

7/10 was the answer

Answer:

7/10

Step-by-step explanation:

Answer:

Step-by-step explanation:

(2,4) is point lying on the line represented by 5x + 2y  = 18.

They are not intercepts.

x-intercept is point where the line crosses the x-axis and so, y-co ordinate at x-intercept is 0.

y-intercept is point where the line crosses they-axis and so,x-co ordinate at y-intercept is 0.

5x + 2y = 18

To find x-intercept, put y = 0 in the equation

           5x = 18

             x = 18/5

             x = 3.6

To find y-intercept, put x = 0 in the equation

          2y = 18

             y = 18/2

             y = 9

x-intercept : (3.6 , 0)

y-intercept :(0, 9)

Answer:

It is true
