Step-by-step explanation:

Sara will have US$ 2,251.02 in the bank after 4 years for her trip to Italy.

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Investment of Sara during her 1st year of college = US$ 2,000

Duration of the investment = 4 years

Annual interest rate = 3%

2. Let's find the future value of this investment after 4 years, using the following formula:

FV = PV * (1 + r) ⁿ

PV = Investment of Sara during her 1st year of college = US$ 2,000

number of periods (n) = 4

rate (r) = 3% = 0.03

Replacing with the real values, we have:

FV = 2,000 * (1 + 0.03) ⁴

FV = 2,000 * (1.03) ⁴

FV = 2,000 * 1.12550881

FV = 2,251.02

Sara will have US$ 2,251.02 in the bank after 4 years for her trip to Italy. Later you round the answer and that gives you 2,240

Answer:

a = -4 and b = -3

Step-by-step explanation:

Step 1: Solve 3a + 5b = -27 for a

3a + 5b = -27

3a + 5b + -5b = -27 + -5b

(Add -5b go both sides)

3a = -5b- 27

3a = -5b - 27

3 3

(Divide both sides by 3)

a = -5 b - 9

3

Step 2: Substitute -5 b - 9 for a in 4a + 10b = -46

3

4a + 10b = -46

4(-5 b - 9) + 10b = -46

3

10 b - 36 = -46

3

(Simplify both sodes of the equation)

10 b - 36 + 36 = -46 + 36

3

(Add 36 to both sides)

10 b = -10

3

10/3 b = -10

10/3 10/3

(Divide both sides by 10/3)

b = -3

Step 3: Substitute -3 for b in a = -5/3 b - 9

a = -5/3 (-3) - 9

a = -4

(Simplify both sides of the equation)

[tex]x=\frac{y}{3b-7}[/tex]

Step-by-step explanation:

Rewrite the equation as [tex]3bx-7x=y[/tex].

Factor  x  out of  3 b x

[tex]x(3b)-7x=y[/tex]

Factor [tex]x[/tex] out of [tex]x(3b)+x*-7[/tex]

[tex]x(3b-7)=y[/tex]

Divide each term by [tex]3b-7[/tex]   and simplify.

Divide each term in [tex]x(3b-7)=y[/tex] by [tex]3b-7[/tex].

[tex]\frac{x(3b-7) }{3b-7} =\frac{y}{3b-7}[/tex]

Step-by-step explanation:

Given parameters:

Distance in a year = 18000miles

Car mileage = 24miles/gallon

Average cost per gallon = $2.72 per gallon

Problem;

Find the error in her calculation;

Step 1

18,000 miles/year    

18, 000 miles = 1,500 miles/month     -- Since there are 12months in a year

12 months

Step 2

1500 miles/month

      Car mileage  = 24miles/gallon

Gallons per month; [tex]\frac{1500}{24}[/tex]   = 62.5gallons/month

125 gallons/month   this is an error and should be 62.5gallons/month

12 miles/gallon  should be 24miles per gallon

Step 3

(125 gallons/month) x ($2.72/gallons) = $340 cost/month

Correct

Step 2 is wrong because it uses wrong values.

Answer:

Step-by-step explanation:

Let m be the number of miles that evelyn can run in 60 minutes.

If evelyn can run 3 miles in 40 minutes, to calculate the number of miles she can run in 60 minutes, we will apply the equality postulate as shown;

3 miles = 40 minutes

m miles = 60 minutes

Cross multiply

40* m = 3* 60

40m = 180

Divide both sides by 40

40m/40 = 180/40

m = 180/40

m = 4.5 miles

The equation that can be used to find m is 40m = 180 and the value of m is 4.5miles

ive done it before

Answer:

Step-by-step explanation:

m<5 and m<4 are  supplementary angles => m<5 + m< 4 = 180

                                                                         m<4 = 180 -77 = 103

m<4 and m<2 are corresponding angles => m<4 = m<2 = 103

The measure of the angle m∠2 is 103.

The supplementary angles are defined as the angles having a sum of 180 degrees. The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

In the given image the given angle is m∠5=77°. The measure of the angle m∠2 will be calculated by using some of the angle properties.

m∠5 and m∠4 are supplementary angles:-

m∠5 + m∠4 = 180

m∠4 = 180 -77 = 103

m∠4 and m∠2 are corresponding angles => m∠4 = m∠2 = 103

Therefore, the measure of the angle m∠2 is 103.

Answer:  Choice D) [tex]x \ge -6[/tex]

=========================================================

Explanation:

Taking the square root of a negative number leads to a nonreal result.

So we want the radicand to be 0 or positive

Set the stuff under the square root to be 0 or larger. Solve for x.

[tex]\frac{1}{3}x+2 \ge 0\\\\\frac{1}{3}x \ge 0-2\\\\\frac{1}{3}x \ge -2\\\\x \ge 3(-2)\\\\x \ge -6[/tex]

If x is -6 or larger, then [tex]\frac{1}{3}x+2[/tex] is 0 or larger leading to some real number for f(x).

The inequality sign does not flip because we multiplied both sides by a positive number. The inequality sign only flips when we multiply both sides by a negative number.

Ok only if yo help me with my last question

Step-by-step explanation:

Answer:

45 degrees

Step-by-step explanation:

Since the angle x and angle 135 degrees are supplementary, you just have to minus 135 from 180 which the answer is 45 degrees.

The value of the angle x will be equal to 45 degrees.

An endlessly long row of evenly spaced dots that spans in both directions makes up a line. Its length is the only dimension it has. A geometry called an angle is created when two line segments, lines, or rays intersect.

Given that the line is crossing the two parallel lines making an angle of 135 degrees with one line. The value of x will be calculated by using the supplementary angle property.

x + 135 = 180

x = 180 - 135

x = 45

Therefore, the value of the angle x will be equal to 45 degrees.
