Answers

Answer 1

The fisherman row 14 mph

Step-by-step explanation:

downstream means to subtract so you subtract 6-4 which will gives you 2 then you multiply 2 times 7 which is 14 because it says hours.

Figure A is a scale image of figure B. What is the value of x?

Answers

Answer:

The value of x = 20.

Step-by-step explanation:

Figure B is the scale image of A.

It is clear that:

side 10 of figure A has the image side of 12.5 in figure B.

which can be obtained by multiplying 10 with 1.25

i.e.

10*1.25=12.5

so the side 16 of figure A must have to be multiplied by 1.25 to get the image the figure B.

so

16*1.25=20

Therefore, the value of x = 20.

Tom rented a truck for one day. There was a base fee of $14.95, and there was an additional charge of 73 cents for each mile driven. Tom had to pay $220.81 when he returned the truck. For how many miles did he drive the truck?

Answers

Answer:

Tom drove 282 miles.

Step-by-step explanation:

x = number of miles driven

220.81 = 14.95 + 0.73x

-14.95       -14.93

205.86 = 0.73x

/0.73        /0.73

282 = x

Bailey can put x houses of his holiday miniature village on each of 7 shelves. He also has 10 houses displayed on his buffet. If he wants to display at least 45 of his houses, how many houses must he put on each of the 7 shelves? Write an inequality to represent this situation

Answers

Answer:

7x + 10 ≥ 45

Step-by-step explanation:

Given that:

Number of shelves = 7

Number of houses to display on each shelf = x

Number of houses to display = atleast 45 (≥)

Number displayed on buffet = 10

Number displayed on buffet + (number of shelves * number per shelf) ≥ number of houses to display

10 + (7 * x) ≥ 45

7x + 10 ≥ 45

All angles in a triangle add up to 180°

Step-by-step explanation:

Step 1: Set up equation

x° + 104° + 32° = 180°

Step 2: Solve for x

Combine like terms:                    x + 136 = 180Subtract 136 on both sides:        x = 44°

Answer:

44°

Step-by-step explanation:

Because Sum of three angles of a triangle equals 180 °

So 180°-(104°+32°)

=180°-72°

=44°

Y: 2y - 3(4y-3) = 9y + 28

Answers

Answer:

y = - 1

Step-by-step explanation:

Given

2y - 3(4y - 3) = 9y + 28 ← distribute and simplify left side

2y - 12y + 9 = 9y + 28

- 10y + 9 = 9y + 28 ( subtract 9y from both sides )

- 19y + 9 = 28 ( subtract 9 from both sides )

- 19y = 19 ( divide both sides by - 19 )

y = - 1

If Serena puts $1000 in a savings account that pays 2% interest compounded annualy, how much money will she have in the account after 10 years? (Hint: To find the amount of money after 1 year. multiply by 1.02.)

Answers

Answer:

5000

Step-by-step explanation:

1000 ÷ 2 = 500 x 10 = 5000

Answer:

$1221.19

Step-by-step explanation:

Formula for compound interest:

A= P(1+r/n)^n x t

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

We know that Serena pays annually meaning yearly (12 months or 1 year)

So after substituting all the numbers in,

A= 1000(1+0.02/12)^(12x10)

We change the rate to 0.02 because we must divide 2% by 100%. And divide the rate by number of times applied per time (n).

DISCLAIMER:

I have not done compound interest questions in a long time but if you want to confirm my answer, go to a calculator site and just input the numbers on there.

What is the equation of the vertical line through (-8, 5)

Answers

Answer:

The equation of the vertical line passing through the point (-8, 5) will be:

[tex]x=-8[/tex]

Step-by-step explanation:

As we have to determine the equations for the horizontal and vertical lines passing through the point (-8, 5).

To determine the equation for the vertical line passing through the point (-8, 5), we must observe that the vertical line will always have the same x-value regardless of y-values.

Therefore, the equation of the vertical line passing through the point (-8, 5) will be:

[tex]x=-8[/tex]

In a group of 30 students. 8 take Italian, 12 take German wind 3 take both languages. How many students in the group neither take German nor Italian?

Answers

Simple, 13 students do not take a language class.

8 french students + 12 Spanish students = 20 language students

3 students take both classes so 20 - 3 = 17 language students.

30 - 17 = 13

Therefore 13 students neither take Spanish nor French.
The answer is 7 students in the group neither take German nor Italian.

That is because 8 students that take Italian + the 12 that take German, and + the 3 student that take both = 23 students.

Since they are 30 students in total and 23 students that take either German, Italian, or both, you subtract the 23 students from the total 30, leaving you with 7 students who neither take German not Italian.

I hope this helps, cause then again idek

how do i find the value of x?

Answers

Answer:

x = 18 (verified by algebra) ✅

Step-by-step explanation:

When we have two similar triangles, we can use a proportion to determine an unknown value.

[tex]\frac{2x + 80}{87} = \frac{80}{60}[/tex]

We will cross multiply to get two equivalent equations that can be solved.

(2x + 80) x 60 = 120x + 4800

We can simplify this by dividing both sides by 24 to get a much simpler equation to work with: 5x + 200.

80 x 87 = 6960

We will also divide this by 24. The answer is 290

5x + 200 = 290

Subtract 200

5x = 90

Divide by 5

x = 18

Now, we can also check to make sure we did everything correctly.

(2(18) + 80) x 60 = 120x + 4800

(36 + 80) x 60 = 120(18) + 4800

116 x 60 = 2160 + 4800

6960 = 6960 ✅

The answer will be X = 18
