Let x represent the smaller angle. Then the larger one is 20+4x. Since they are complementary, their sum is 90. (All measures are degrees.)

90 = x + (20+4x)
90 = 5x +20
70 = 5x
14 = x

The smaller angle is 14°.
The larger angle is 76°.

current rules for telephone area codes allow the use of digits 2-9 for the first digit and 0-9 for the second and third digits.
lukranit [14]
In this question, there are 10 digit phone number which was divided into 3-3-4 digits. Every first digit of the division should be 2-9 which mean only 8 possibilities. The other digits would be 0-9 which mean 10 possibilities. Then the calculation would be:

8*10*10   *    8*10*10    *   8*10*10*10  = 8^3 * 10*7= 512 * 10^7= 5.12 * 10^9

If you convert <span>400,000,000 into the scientific form it will become 4* 10^8. Since 5.12*10^9 > 4 * 10^8, then it is clear that the number should be enough</span>

Jamal worked over summer at his dads office. He earned $2200 total. He is planning on spending his money on a $50 per month gym
Tju [1.3M]

Answer: He will have $1974 in April.

Step-by-step explanation:

Given : Total money he earned =  $2200

He spent $50 per month gym membership, a $68 monthly phone plan $48 monthly gas plan and $60 monthly fun plan.

So , Money he has left  = Money he earned - Total expenditure

= $ ( 2200- (50+68+48+60))

=  $ (2200- 226)

= $ 1974

Hence, He will have $1974 in April.

An open box with a square base is to be made from a square piece of cardboard 24 inches on a side by cutting out a square from e
laila [671]

Answer:

x=4 Inch

Step-by-step explanation:

Length of the Square = 24 Inches

If a Square of Length x cm is cut out from each corner

Length of the Box = 24-x-x=(24-2x) Inches

Width of the Box =24-x-x=(24-2x) Inches

Height of the box = x inches

Volume of a Cuboid = Length X Width X Height

V(x)= x(24-2x)(24-2x)

Simplifying

V(x)=4x(12-x)(12-x)

To determine the value of x at which V is largest, we take the derivative of V(x) and solve for the critical points.

V(x)=4x(12-x)(12-x)

V^{'}(x)=12(x-12)(x-4)

Set the derivative equal to zero to obtain the critical points

V^{'}(x)=12(x-12)(x-4)=0\\Since \: 12\neq 0\\(x-12)(x-4)=0\\x-12=0 \:or\: x-4=0\\x=12 \:or\: x=4

x cannot be equal to 12 as it divides the length of the square cardboard into exactly two equal parts.

When x=4

V(4)=4*4(12-4)(12-4)=16*8*8=1024 Cubic Inches

When x=4 Inch, the volume, V of the open box is largest.

write the correct Equation and Solve. Use x for the variable. The difference of four times a number and seven is thirteen​
Verizon [17]

Answer:

Step-by-step explanation:

Let the number be x

4times a number  =4x

The difference of four times a number and seven : 4x - 7

4x - 7 = 13

      4x = 13 + 7

      4x = 20

        x = 20/4

        x = 5
