The perimeter of a rectangle is 70cm.
Its shortest side has a length of 10cm.

Answer:

6i

Step-by-step explanation:

[tex]\sqrt{-36} = \sqrt{36} \sqrt{-1}[/tex]

[tex]\sqrt{36}[/tex] is 6 and symbol for [tex]\sqrt{-1}[/tex] is i for imaginary. So your answer will be 6i

Answer: 20 pens

5x5=25

5x4=20

is this correct?

a * b = -70

a + b = -9......a = -9 - b

b(-9 - b) = -70

-b^2 - 9b + 70 = 0

(-b + 5)(b + 14) = 0

-b + 5 = 0

5 = b

b + 14 = 0

b = -14

ur numbers are -14 and 5

-14 * 5 = -70

-14 + 5 = -9

Answer:

The black-and white printer print can print 15 pages per minute.

Step-by-step explanation:

The given modeled equations are

3b + 5c = 70...(i)

6b + 9c = 135...(ii)

where b is the number of pages per minute of the black-and-white printer and c is the number of pages per minute of the color printer.

From equation (i), we have

[tex]3b=70-5c \\\\\Rightarrow b = \frac {70-5c}{3} \cdots(iii)[/tex]

Now, substitute the value of b in equation (ii), we have

[tex]6\times \frac {70-5c}{3}+9c=135 \\\\\Rightarrow 2(70-5c)+9c=135 \\\\\Rightarrow 140 - 10c+9c=135 \\\\\Rightarrow -c=135-140=-5 \\\\\Rightarrow c=5x^{2}[/tex]

By using equation (iii), we have

[tex]b = \frac {70-5\times5}{3}=\frac{45}{3}=15[/tex]

Hence, the black-and white printer print can print 15 pages per minute.

The black-and-white printer can print 15 pages per minute.

Given equations:

[tex]3b+5c=70[/tex]    ........(i)

[tex]6b+9c=135[/tex]  ........(ii)

Where b is the number of pages per minute of the black-and-white printer and c is the number of pages per minute of the color printer.

Solve the system of equations by substitution method

From (ii)

[tex]6b=135-9c\\b=\frac{135-9c}{6}[/tex]     ........(iii)

Put the value of b in (i), we get

[tex]3(\frac{135-9c}{6} )+5c=70\\\frac{135-9c}{2} +5c=70\\135-9c+10c=140\\c=5[/tex]

put c = 5 in (iii)

[tex]b=\frac{135-9(5)}{6} =\frac{90}{6} =15[/tex]

Therefore, The black-and-white printer can print 15 pages per minute.

10 to the power of 4 is equal to 10,000.

To calculate 10 to the power of 4 as a decimal, you need to raise the base number (10) to the exponent (4).

Here are the steps to compute it:

Step 1: Start with the base number, which is 10.

Step 2: Multiply the base number (10) by itself 4 times, since the exponent is 4. The calculation looks like this:

10 x 10 x 10 x 10 = 10,000

Step 3: The result of multiplying 10 by itself 4 times is 10,000.

So, 10 to the power of 4 (10⁴) is equal to 10,000.

Hence 10 to the power of 4 is equal to 10,000.

Answer:

She made a profit of 1,335 cedis

Step-by-step explanation:

Here, we want to calculate the profit made

Profit is selling price - cost price

Her cost price is 65 credits

For her selling price;

she sells 3 for 20 cedis

So the price she sold 210 will be;

(210 * 20)/3 = 1,400 cedis

So the profit made is;

1,400-65 = 1,335 cedis

Answer:

0.8 or 8/10

Step-by-step explanation:

Answer:

4/5 or 0.8

Step-by-step explanation:

so, -4/4 and 1/5 are both already fractions.

160% as a decimal would be 1.6. 1.6 as a fraction would be 8/5.

-4/4 is just -1

-1+1/5+8/5

so, -5/5 +1/5 +8/5

-5/5 plus 9/5

4/5

the answer would be 4/5 or 0.8

Answer:

{0, 3.75, 7.5, 11.25, 15, 18.75, 22.5}

Step-by-step explanation:

Since the values in this function cannot go on infinitely this is a discrete funciton.

Its basically asking how much he can spend on drinks with 23$ if they are each 3.75$, this means that he can buy at most 6 drinks. Imagine a disctrete graph with a point on every value he spends per drink, (0,0) (1 , 3.75) (2 , 7.5) etc.

As our bright fellow shadow188 has stated, y is the range or the output so you list the possible outputs for the range in bracets.

I hope you found this helpful, ik its a little late.

The required range will be $3.75 ≤ y ≤ $23 for the function.

Given that,
Brandy only has $23 in cash to spend on drinks, and the concession stand charges $3.75 for a drink.
x represents the number of drinks purchased, and y is the amount of money spent on drinks, what is the range in this situation is to be determined.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
Let the x be the cost of the drink and y be the total amount of money spent,
Since there are concession stand charges of $3.75 also.
So the minimum charge will be $3.75 whether bought the drink or not, and Brandy has $23 to spend on drinks so the maximum will be $23.
So, the range can be given as $3.75 ≤ y ≤ $23.

Thus, the required range will be $3.75 ≤ y ≤ $23 for the function.

Answer:

16,712.38

Step-by-step explanation:

Periodic interest rate 7.2%/12 = 0.6%

First find the monthly payment

M = $14,000 * 0.006(1 +0.006)^60/(1+0.006)^60-1 = 278.54

The total payment is $278.54 * 60= $16,712.38

Jesse's total payment amount for this loan is $16,712.38

Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.

Compound Interest =P(1+r/n)^rt

We are given that Jesse took out a $14,000 car loan for 5 years at a 7.2% interest rate.

Periodic interest rate = 7.2%/12

= 0.6%

First we need to find the monthly payment

M = $14,000 x 0.006(1 +0.006)^60/(1+0.006)^60-1

M = 278.54

The total payment is

$278.54 x 60= $16,712.38

Hence, Jesse's total payment amount for this loan is $16,712.38

Step-by-step explanation:

the domain is the set of values of what the x value can be. This function is parabolic and upside down, it can have a range of x values from - infinity to positive infinity. The function is most likely y=-x^2 +2

range is the output (y values) the function can possibly have. the max is 2 and includes 2 so we use bracket for that. The smallest y value can reach towards negative infinity.
