Answer:

13 rabbits   15 turtles

Step-by-step explanation:

 T + R = 28

3T +5R = 110

    Multiply the first by -3 to eliminate T

B. 42.79

Step-by-step explanation:

There's a trick to dividing by 10ths, you just move the decimal point one space to the left.

1/10 of 1234 = 123.4

1/10 of 98.7654 = 9.87654

Hey there!

1/10 of 427.9

Answer: n = 13

Step-by-step explanation:

To find n, you can look at the equation and see that n is being multiplied by 3 to equal 24. Since 8 times 3 equals 24, you can substitute to solve:

8 = n - 5

n = 13

Therefore, through simplification, n is equal to 13.

Considering that the logo is composed by a semi-circle, a square and a right triangle, it's area is of 143.47 square inches.

The area of a semi-circle of radius r is given by:

[tex]A = 0.5\pi r^2[/tex]

In this problem, the radius is of r = 7 in, hence it's area in square inches is of:

[tex]A_{sc} = 0.5\pi \times 7^2 = 76.97[/tex]

The area of a square of side l is given by:

[tex]A = l^2[/tex]

In this problem, we have that l = 7 in, hence it's area in square inches is of:

[tex]A_{sq} = 7^2 = 49[/tex]

The area of a right triangle of sides a and b is given by:

[tex]A = \frac{ab}{2}[/tex]

In this problem, we have that a = 5 in, b = 7 in, hence it's area in square inches is of:

[tex]A_{rt} = \frac{5 \times 7}{2} = 17.5[/tex]

It is given by the sum of the areas of each figure, hence:

[tex]A = A_{sc} + A_{sq} + A_{rt} = 76.97 + 49 + 17.5 = 143.47[/tex]

It's area is of 143.47 square inches.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

We already know 2 angles of each triangle, so we can find the third angle

The third angle of LMN = 180 - 115 - 21 = 54
The third angle of PQR = 180 - 21 - 49 = 110

So, the 3 angles of each triangle are not similar to each other
And there are no information about the sides.


So, I think the safest option is to go with "there's not enough information to determine whether they are similar or not."

But, the 3 sides of LMN by normal vision is longer than PQR, so you can also go with LMN is not similar to PQR.

Answer:

f(x) = x⁴ - 13x³ + 39x² + 13x - 40

Step-by-step explanation:

If the zeroes are 8, 5, 1 and -1, then x = 8, x = 5, x = 1, x = -1

⇒ x - 8 = 0

⇒ x - 5 = 0

⇒ x - 1 = 0

⇒ x + 1 = 0

⇒ f(x) = (x - 8)(x - 5)(x - 1)(x + 1)

⇒ f(x) = x⁴ - 13x³ + 39x² + 13x - 40

Step-by-step explanation:

The same way that you can perform any (most) operation(s) on both sides of an equation, you can do the same to the numerator and denominator of a fraction.  Thus, simply multiply the numerator (4) and the denominator (10) to get 40/100 from 4/10.  Then, because 40/100 and 8/100 have the same denominator, simply add the numerators 40 and 8 to get 48/100.

Hope it helps :) and let me know if you want me to elaborate.

Answer:

B

Step-by-step explanation:

Because of 4/10 having 10 you have to times to it get's to 100 since the denominators isn't the same.

So how many times do you have to times to get to 100=?

10 is the correct answer so since you times 10 ten times now you will have to also times 4 by 10 what is 4 x 10=?

10 x 4=40 so now we can finally add.

40 + 8=48 out of 100 so out answer is 48/100

Do you want to see the answer in different form.

Like these

Decimal form=0.48

Percent form=48%

or written form= forty eight out of one hundred.

Jennifer's January finance charge will be $0.6717 more if it is calculated using the previous balance method.

Previous balance method: Interest charges are based on the amount owed at the beginning of the previous month's billing cycle.

Adjusted balance method: Based on finance charges on the amount(s) owed at the end of the current billing cycle after credits and payments have been posted.

The total amount on which interest will be applied using the previous balance method = 807.94+41.81+75+18.65 = $943.4

So, interest levied on this= 943.4*10.22*(30/360)*(1/100)= $8.0346

Now, the total amount on which interest will be applied using the adjusted balance method = 807.94+41.81+75+18.65-53.88-25 = $864.52

So, interest levied on this = 864.52*10.22*(30/360)*(1/100)= $7.3628

Difference between charges by previous balance method and adjusted balance method = 8.0346-7.3628 = $0.6717

Therefore, Jennifer's January finance charge will be $0.6717 more if it is calculated using the previous balance method.

The expression 20x + 10y represents the profit and the maximum profit is N 470, and the greatest number of packets she buys is 50.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have:

A shopkeeper orders packets of soap powder. The cost price of a large packet is N180 and that of a small packet is N80.

Let's suppose the number of the large packets is x

The number of small packets is y.

The greatest number of packets she buys = 4000/80 = 50

The maximum amount can be spent = N 4000

180x + 80y ≤ 4000

Profit will be:

= 20x + 10y

The arrangements gave maximum profit:

x         y       Cost      Profit

10       27     3960      470

11        25     3980      470  

12       23      4000     470

The maximum profit = N 470

Thus, the expression 20x + 10y represents the profit and the maximum profit is N 470, and the greatest number of packets she buys is 50.
