Answer:

Step-by-step explanation:

=−10.44−4.2−(−6.85)

=−14.64−(−6.85)

=−7.79

Answer:

-7.79

Step-by-step explanation:

Given problem,

→ -16.26 - (-5.82) - (4.20) - (-6.85)

Let's simplify the problem,

→ -16.26 - (-5.82) - (4.20) - (-6.85)

→ -16.26 + 5.82 - 4.20 + 6.85

→ -10.44 + 2.65 = -7.79

Hence, the answer is -7.79.

New width: 10 cm, new length: 15 cm

Or new width 15 and new length 10

1) Since this rectangle, has been scaled up by a factor k=5 (since 5 >1 then the rectangle has been enlarged)

2) Then we can write the following about their new dimensions:

w = 2 x 5 = 10

l = 3 x 5 = 15

3) So the answer is 10 x 15

The most appropriate choice for speed will be given by-

Speed of plane in still air = 610 miles/hour

Speed of wind = 20 miles/hour

What is speed?

Distance travelled by a body in unit time is called speed.

Let the speed of plane in still air be x miles/hour

Speed of wind be y miles/hour

A plane traveled 3465 miles with the wind in 5.5 hours

So,

x + y = [tex]\frac{3465}{5.5}[/tex]

x + y = 630.......(1)

The plane travelled 3245 miles against the wind in the same amount of time

so,

x - y = [tex]\frac{3245}{5.5}[/tex]

x - y = 590.......(2)

Adding (1) and (2),

2x = 1220

x = [tex]\frac{1220}{2}[/tex]

x = 610 miles/hour

Putting the value of x in (1),

610 + y = 630

y = 630 - 610

y = 20 miles/hour

Speed of plane in still air = 610 miles/hour

Speed of wind = 20 miles/hour

INAL ANSWER: 125

We are given the quadratic function c(p) = p^2 - 28p + 250 and we need to rewrite this in such a way that the minimum value is easy to find.

Remember that the vertex

where (h, k) is the vertex or the minimum point.

We use completing the squares method to do this. We divide the second term, -28p, by 2p, then square it.

We add 196 to p^2 - 28p to make it equal to (p - 14)^2, but since it will change the value of the equation, we need to subtract the same value from 250 so that the net effect is zero.

The equation is c(p) = (p - 14)^2 + 54.

The values of m that can fit into the equation m² = 16 will be m = ±4.

It should be noted that a equation is simply used to illustrate the relationship between the variables that are given. From the information, it should be noted that the equation is illustrated as m² = 16.

Since m² = 16, we need to find the square root. This will be illustrated as:

m² = 16

m = ✓16

m = 4

It should be noted that (-4) × (-4) = 16 and 4 × 4 = 16.

Therefore, the correct option is m = ±4

Answer: 17 million

Step-by-step explanation:

      We will set up a proportion to solve. We also will divide 26% by 100 to get a decimal, 0.26. We know that 26% of college students was 4.4 million, but we want to find 100%.

     [tex]\displaystyle \frac{0.26}{4.4\text{ million}} =\frac{1}{x\text{ million}}[/tex]

      Now, we will cross-multiply.

0.26 * x = 1 * 4.4

0.26x  = 4.4

      Lastly, we will divide both sides of the equation by 0.26. Then, we will round to the nearest million.

x = 16.923

x ≈ 17 million

The expression equivalent to [-40 + (-20) + (-60)] is [−20 + (−40) + (−60)]

As per the question statement, we are provided with a linear expression of [-40 + (-20) + (-60)], and four options.

We are supposed to determine the one expression from the given options, that is equivalent to the question mentioned expression of [-40 + (-20) + (-60)].

To solve this question, we will first calculate the value of the question mentioned equation, and then, calculate and compare the values of individual expressions provided in the options, to obtain our desired answer.

Therefore, [-40 + (-20) + (-60)] = [-40 - 20 -60]

or, [-40 + (-20) + (-60)] = -( 40 + 20 + 60)

or, [-40 + (-20) + (-60)] = -120.

Now, coming to the first option, expression [−40 − (20 − 60)] equates to

[-40 - (-40)] = (-40 + 40) = (40 - 40) = 0,

And [0 ≠ (-120),

Hence, [−40 − (20 − 60)] is not the equivalent expression to

[-40 + (-20) + (-60)].

Now, coming to the second option, expression [-(40 − 20) + (-60)] equates to [-(20) + (-60)] = (-20 - 60) = -(20 + 60) = (-80),

But again, [(-80) ≠ (-120)],

Hence, [-(40 − 20) + (-60)]  is not the equivalent expression to

[-40 + (-20) + (-60)].

Coming to the third option, expression [40 + 20 + 60] equates to (120)

But again, [120 ≠ (-120)],

Hence, [40 + 20 + 60] is not the equivalent expression to

[-40 + (-20) + (-60)].

Finally, Coming to the last option, expression [−20 + (−40) + (−60)] equates to (-20 - 40 - 60) = -(20 + 40 + 60) = (-120).

And [(-120) = (-120)],

Hence, [−20 + (−40) + (−60)]  is the required equivalent expression to

[-40 + (-20) + (-60)].

The cost of the car the Gilberts purchased before tax is  $13,820.52.

Tax is a compulsory amount that is levied on a good or service by the government. A sales tax is a tax that is levied on the purchase of a good and service. Taxes increase the cost of a good or service.

The equation that can be used to determine the cost of the car after tax is:

(1 + sales tax) x cost before tax = cost after tax

(1 + 0.05) x c = $14,512

1.05c = $14,512

In order to determine the value of c, divide both sides of the equation by 1.05:

c = $14,512 / 1.05

The lengths of the rectangle for which the area will be less than 125 cm² is 5 < m < 25

In this question, we have been given the width of a rectangle is fixed at 5 cm.

We need to determine​ (in terms of an​ inequality) those lengths for which the area will be less than 125 cm²

Let 'm' be the length of the rectangle.

The area of the rectangle is:

A = length × width

The area of the rectangle should be less than 125 cm²

5 × m < 125

Divide both the sides of the inequality by 5

m < 25

This means, the length of rectangle should be less than 25 cm

But length is always greater than the width of the rectangle.

So, we get an inequality 5 < m < 25

Therefore, the lengths of the rectangle for which the area will be less than 125 cm² is 5 < m < 25

Let the given angles formed by transversal r, adjacent to line m be angle 1, and to line n be angle 2.

Now, the vertically opposite angle to angle 1 will be equal to it as they both are congruent.

The vertically opposite angle equal to angle 1 would be corresponding to angle 2 and corresponding angles formed by a transversal are equal and congruent.

Moreover, angle 1 and angle 2 are alternate exterior angles and by Alternate Exterior Angles Theorem, they are congruent.

Let n be the unknown number.

The quotient is the result obtained by dividing one number by another.

Therefore, the quotient of a number and 8 is ⁿ/₈.

If the quotient of a number and 8 is added to 1/4 the result is 7/8:

[tex]\implies \dfrac{n}{8}+\dfrac{1}{4}=\dfrac{7}{8}[/tex]

To solve, make the denominators of all the fractions the same:

[tex]\implies \dfrac{n}{8}+\dfrac{1 \cdot 2}{4 \cdot 2}=\dfrac{7}{8}[/tex]

[tex]\implies \dfrac{n}{8}+\dfrac{2}{8}=\dfrac{7}{8}[/tex]

[tex]\textsf{Apply the fraction rule} \quad \dfrac{a}{c}+\dfrac{b}{c}=\dfrac{a+b}{c}:[/tex]

[tex]\implies \dfrac{n+2}{8}=\dfrac{7}{8}[/tex]

Multiply both sides by 8:

[tex]\implies \dfrac{8(n+2)}{8}=\dfrac{7 \cdot 8}{8}[/tex]

[tex]\implies n+2=7[/tex]

Subtract 2 from both sides:
