Please help!!

Answers

Answer 1

9514 1404 393

Answer:

  a. 38

  b. 95

  c. 57

Step-by-step explanation:

In this context, you can consider "of" to mean "times." It can also be helpful to think of % as meaning /100.

a.  p = 20% × 190

  p = 20/100 × 190 = 38 . . . . you have 38 pennies

__

b. 190 = 200% × r

  190 = 200/100 × r . . . . replace % with /100

  190 = 2 × r . . . . . . . . . simplify the fraction

  190/2 = r = 95 . . . . you have 95 rare coins

__

c. n = 60% × r

  n = 60/100 × 95 = 57 . . . . you have 57 nickels

A line is parallel to y = 3x + 5 and
intersects the point (-2, 6). What is
the equation of this parallel line?
Start by entering this into point-slope form.
y- [?] = [](x
](x-[]).

Answers

Answer:

Im not like 100% sure but i think you answer is

y-6=3[x-(-2)]

y=6+3x+6

y=3x+12

And i believe that this is parallel to y

Answer:

y = 3x + 12

Step-by-step explanation:

Parallel lines have same slope

Given line

y = 3x + 5

The line that passes through (-2, 6) and with the slope of 3 is:

y - y₁ = m(x - x₁)y - 6 = 3(x - (-2))y - 6 = 3(x + 2)

Convert the equation into slope-intercept form:

y - 6 = 3x + 6y = 3x + 6 + 6y = 3x + 12

A new car is purchased for 24600 dollars. The value of the car depreciates at 5.5% per year. To the nearest year, how long will it be until the value of the car is 11300 dollars?

Answers

Answer:

The number of years until the value of the car is 11300 dollars is 9 years.

Step-by-step explanation:

This can be calculated using the following formula:

Value of the Car = Purchase cost - (Annual depreciation expenses * N) ........ (1)

Where;

N = Number of years until the value of the car is 11300 dollars

Purchase cost = $24,600

Annual depreciation rate = 5.5%

Annual depreciation expenses = $24,600 * 5.5% = $1,353

Value of the car = $11,300

Substituting the value into equation (1) and solve for N, we have:

$11,300 = $24,000 - ($1,353 * N)

$1,353 * N = $24,000 - $11,300

$1,353 * N = $12,700

N = $12,700 / $1,353

N = 9.38654841093865

Rounding to the nearest year as required by the question, we have:

N = 9

Therefore, the number of years until the value of the car is 11300 dollars is 9 years.

Kenneth Drew a scale drawing of an apartment the scale of the drawing was 2 meters:1 meter the living room is 6 m long in real life how long is the living room in drawing

Answers

Answer:

3 meters

Step-by-step explanation:

Given the scale drawing :

2m : 1m

Length of living room in real life = 6 m long

2 meter = 1 meter

Real life = scale drawing

If length = 6 meter long ;

using cross multiplication :

2 meter = 1 meter

6 meter = x

2x = 6

x = 6/2

x = 3 meter

Length of living room in drawing = 3 meters

The segments formed by the altitude to the hypotenuse of a right triangle are 8 and 10. Find the shorter leg of that triangle.

Answers

Answer: 6

Step-by-step explanation:

Since the hypothenuse is 10 and the larger leg of the triangle is given as 8, the shorter leg will be calculated as the square of the hypothenuse minus the square of the longer leg after which we find the square root of the value gotten. This will be:

Shorter leg² = 10² - 8²

Shorter leg² = 100 - 64

Shorter leg² = 36

Shorter leg = ✓36

Shorter leg = 6

Answers

Answer:

8 hours 20 minutes

Step-by-step explanation:

Given that :

Time Rachel left for school = 7:45 a.m

Time for which Rachael was gone :

4:05 p.m - 7:45 a.m

7:45 a.m to 3:45 p.m= 8 hours

3:45pm to 4:05 pm = 20 minutes

= 8 hours 20 minutes
