Mathematics
1 answer:
ycow [4]3 years ago
3 0

Answer:

Correct answer = 20 miles

Step-by-step explanation:

The mistake she made was that she made was that she  multiplied the amount with 3 instead of dividing it.

The incorrect way -

$60 = 3 × 60 = 90 (Her multiplication is also incorrect as 3 × 60 = 180)

Corrected method -

$60 = \frac{60}{3} = 20 miles

<h3>Hope you understood. Please mark my answer as the brainliest.</h3>

Jerry has a part-time job at a supermarket. The ordered pairs show the number of hours he worked for (input values) and the numb
Karo-lina-s [1.5K]

Answer:

Yes

Step-by-step explanation:

The ordered pairs are (6,72) (8,96) (5.5, 66) (9,108) (7,84).

The number of hours worked is x and the money earned is  y.

Let us divide the values of y by x

\dfrac{72}{6}=12

\dfrac{96}{8}=12

\dfrac{66}{5.5}=12

\dfrac{108}{9}=12

\dfrac{84}{7}=12

The fuction which defines the above ordered pairs is y=12x

It can be seen that the amount of money earned is 12 times the number of hours worked.

So, per hour Jerry earns 12 dollars.

Hence, the ordered pairs are relation.

How do you do this I have no idea and this thing has to be 20 characters long so all right
Ronch [10]
-3(5/6)v - 1 = -6(3/4)

To start off, we can simplify by multiplying the fractions with their whole numbers.

-15/6x - 1 = -18/4

Further simplify

-5/2x - 1 = -9/2

Now we can multiply everything times 2 to get rid of the fractions

-5x - 2 = -9

Now we will isolate the x value. Add 2 to both sides.

-5x = -7

Finally, divide all by -5 to get the final answer.

x = 7/5

Hope I helped you out!

By what percentage will an amount gro in 10yeare if it is invested at 5% p.a. compounded monthly​
lora16 [44]

Answer:

64.7%

Step-by-step explanation:

To solve this problem we use compounded interest formula.

a = p(1 + (r \div n))^{nt}

a = amount

p = principle

r = interest rate

n = number of times compounded in a period

t = time period

a = 1000(1 + (.05 \div 12)^{12 \times 10}

a = 1647.01

1647.01-1000 = 647.01

647.01/1000 = 0.64701

0.64701*100% = 64.7%
