Answer:

Given:

Solution:

Let's assume Width of rectangle be x and Length of rectangle be x + 7 respectively.

Using formula

[tex] \\ \: \: \: \: \pink{ \dashrightarrow \: \: \: \: \sf { \underbrace{Area_{(Rectangle)} = Length × Width }}} \\ \\ [/tex]

On Substituting the required values, we get;

[tex]\\ \: \: \: \: \dashrightarrow \: \: \: \: \sf (x)(x + 7) = 744 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf {x}^{2} + 7x = 744 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf {x}^{2} + 7x - 744 = 0 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf {x}^{2} + 31x - 24x - 744 = 0 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf x(x + 31) - 24 (x + 31) = 0 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf (x + 31)(x - 24) = 0 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf x = 24 \: or \: - 31 \\ \\ [/tex]

As we know that width of the rectangle can't be negative. So x = 24

Hence,

[tex] \therefore[/tex]Length of rectangle is 31 yards and Width is 24 yards.

Answer:

C) All squares are rhombuses. Rhombeses have 4 sides that are the same length. Therefore, all squares have 4 sides that are the same length.

Step-by-step explanation:

Answer:

248

Step-by-step explanation:

Consecutive angles of a parallelogram are supplementary.

56 + y = 180

y = 180-56

y =124

The opposite angles of a parallelogram are equal.

x = y = 124

x+y = 124+124

      =248

Answer:

x + y = 248

Step-by-step explanation:

consecutive angles in a parallelogram sum to 180°

opposite angles are congruent

x + 56° = 180° ( subtract 56° from both sides )

x = 124°

then

y = x = 124 , so

x + y = 124 + 124 = 248

Answer:

The future value after 4 years will be $8156.49 if the value of the car today is $13,000 but will lose 11% of its value each year for the next several years.

Based on an estimated growth rate, the future value is the amount that an asset will be valued at a future date. The computation assumes that at the start date, a fixed amount of cash is made available for investment and that it increases at a constant rate until the selected future date.

We have:

Current value of the car = $13,000

Depreciation rate = 11%

Time n = 4 years

[tex]\rm Future \ value = (value \ at \ present) ( 1- \dfrac{depreciation \ rate}{100})^n[/tex]

[tex]\rm Future \ value = (13000)(1-\frac{11}{100} )^4[/tex]

Future value = $8156.49

Thus, the future value after 4 years will be $8156.49 if the value of the car today is $13,000 but will lose 11% of its value each year for the next several years.

Answer:

Two right angles = 180 degrees

Step-by-step explanation:

A right angle = 90 degrees

The sum of the interior angles of a triangle = 180 degrees

Two right angles (2 * 90) = 180

180 = 180

Therefore, the sum of the interior angles of  any triangle is equal to two right angles.

Rina Take home pay is $457.20

The basic salary divided by the Gross salary is multiplied by 100. The result is the percentage of gross salary.

Given that:

gross salary = $624

14% income tax = 624* 0.14 = $87.36

group health plan = $4.25

Company retirement = 624 * 0.060 =$37.44

Social Security = 624 * 0.0605 = $37.752

Home pay= 624 - 87.36 - 4.25 - 37.44- 37.752

= 457.198

Her take home pay is $457.198

if she gets a $35 raise per pay period,

So, new gross salary would be,

= $624 + $35

= $659.

Again, we have

14% Income tax = 659 * 0.14 = $92.26

Group health plan = $4.25

Company retirement = 659 * 0.060 = $39.54

Social Security = 695* 0.0605  = $39.8695

Home take pay,

=659-39.8695 - 45.825 - 39.54-92.26

=441.5055

Her take home pay is $441.5055

#SPJ1

Answer:

z = 7/3 is extraneous.

Step-by-step explanation:

√(z^2+8) = 1 - 2z

z^2 + 8 = (1 - 2z)^2

z^2 + 8 = 1 -4z + 4z^2

3z^2 - 4z - 7 = 0

3z^2 + 3z - 7z - 7 = 0

3z(z + 1) - 7(z + 1) = 0

(3z - 7)(z + 1) = 0

3z = 7, z = -1

z = 7/3, -1.

One of these might be extraneous.

Checking:

√(z^2+8) = 1 - 2z, if z = -1:

√(1 + 8) = 3, -3

1 - 2(-1) = 3.    So its not z = -1

if z = 7/3

√((7/3)^2 + 8) = 13.44

1 - 2(7/3) = -3.66

So its z = 7/3

Answer:

[tex]z=\dfrac{7}{3}[/tex]

Step-by-step explanation:

Given equation:

[tex]\sqrt{z^2+8}=1-2z[/tex]

Square both sides:

[tex]\implies (\sqrt{z^2+8})^2=(1-2z)^2[/tex]

[tex]\implies z^2+8=1-4z+4z^2[/tex]

Subtract [tex]z^2[/tex] from both sides:

[tex]\implies 8=1-4z+3z^2[/tex]

Subtract 8 from both sides:

[tex]\implies 0=-7-4z+3z^2[/tex]

[tex]\implies 3z^2-4z-7=0[/tex]

Rewrite the middle term:

[tex]\implies 3z^2+3z-7z-7=0[/tex]

Factor the first two terms and the last two terms separately:

[tex]\implies 3z(z+1)-7(z+1)=0[/tex]

Factor out the common term [tex](z+1)[/tex]:

[tex]\implies (3z-7)(z+1)=0[/tex]

Therefore:

[tex]\implies (z+1)=0 \implies z=-1[/tex]

[tex]\implies (3z-7)=0 \implies z=\dfrac{7}{3}[/tex]

To find the extraneous solution (the root that is not a root of the original equation), enter the two found values of z into the original equation:

[tex]\begin{aligned}z=-1\implies \sqrt{(-1)^2+8}&=1-2(-1)\\\implies 3&=3\implies \textsf{true}\\\end{aligned}[/tex]

[tex]\begin{aligned}z=\dfrac{7}{3} \implies \sqrt{\left(\frac{7}{3}\right)^2+8}&=1-2\left(\frac{7}{3}\right)\\\implies \dfrac{11}{3} &=-\dfrac{11}{3}\implies \textsf{false}\end{aligned}[/tex]

[tex]\textsf{As}\: \dfrac{11}{3} \neq -\dfrac{11}{3}\:\textsf{then}\: z=\dfrac{7}{3}\:\textsf{is the extraneous solution}[/tex]

the answer is 17,202 feet

The bird (B) from its nest (N) is 17202 ft.

Trigonometric functions defined as the functions which show the relationship between angle and sides of a right-angled triangle.

This is very obviously a right triangle problem.

Side BO is the hypotenuse of the triangle, measuring 21000.

Side BN is the side adjacent to the given angle B, 35 degrees.

This is the cosine ratio:

cos∅ = adj/hyp

substitute the values

cos35° = x/21000 and solving for x:

21000.cos(35°) = x

x = 17202.19 or, rounded as we need:

x = 17202

Answer:

44 minutes

Step-by-step explanation:

Given:

Michelle started doing a puzzle at 7:50 p.m. She finished the puzzle at 8:34 p.m.

To Find:

How long did Michelle work on the puzzle?

Solve:

Began Time ⇒ 7:50 p.m

End Time     ⇒ 8: 34 p.m

Since they are both p.m we could just subtract 8:34 by 7:50.

But first we know that:

8: 34 the 34 can't be subtracted by 7:50 the 50.

Thus we know that:

1 Hour = 60 minutes

Hence,

changing 8:34 p.m from 1 hour to 60 minutes. Which given us 7:94.

Then,

7:94 - 7:50

= 44

Hence, Michelle work on the puzzle for 44 minutes.

I don't know the options of the pull-down menus, so I will give you my best guesses based on the facts :

the domain of a function is the set or interval of all valid x (or input) values.

the range of a function is the set of interval of all valid y (or functional result) values.

so, clearly, x is in the interval (-infinity, +infinity). which is therefore the domain.

please conduct the round brackets. they indicate that the specified interval limits are not included (as infinity is not a value, only a concept, and can never be reached).

and y is in the interval of (0, +infinity). which is therefore the range.

we have to use the round brackets also for 0, as the function will never deliver the value 0, but its tendency or limit goes there (but again, only in infinity, which will never be reached).

the function continuously decreases when x increases.

again, I am not sure what the options are here, and what your teacher wants to "hear".
