Jane Marko buys a car for $43,900.00. in three years, the car depreciates 48% in value. How much is the car worth in three years

Oduvanchick [21]

So we want to know what is the value of the car after three years if the car depricates in value for 48% and we know that the initial value of the car is 43900$. So if the price depricates for 48%, that means the new value is 52% of the initial value so: 43900$*0.52=22828$. So C is the correct answer.

Phillipe has 320 pieces of

tankabanditka [31]

The number of candies that will be left over after giving everyone an equal amount is equal to 23.

Given the following data:

Total number of candy = 320 pieces

Number of classmates = 27 classmates

To calculate the number of candies that will be left over after giving everyone an equal amount:

In this exercise, you're required to determine the number of candies Phillipe would have as left over after giving everyone in his class an equal amount of candies.

<h3>How to solve this word problem.</h3>

Thus, we would find the number of times 27 would divide 320 without any remainder.

$\frac{320}{27} = 11 \frac{23}{27}$

From the mixed fraction, we can deduce that the remainder is 23.

Therefore, the number of candies that will be left over after giving everyone an equal amount is equal to 23.

Complete the equivalent equation for -7x-60 =x^2 +10x

alex41 [277]

Answer:

(x+12)(x+5)

Step-by-step explanation:

Formula use: a²+bx+c

Make one side equal to zero:

Original:

-7x-60 =x² +10x

New:

x² + 17x + 60

Multiply A with C

New:

(1)x x 60 = 60

Find factors of 60 that when added, equal to 17.

New:

10 × 6, 60 × 1, 20 × 3, 5 × 12, 4 × 15

5 times 12 equal 60, but when added equal to 17.

Replace the 17 with 5 and 12

New:

x² + 5x + 12x + 60

Break them off into two equations

New:

x² + 5x l 12x + 60

Divide each equation into it's simpilest form. Make sure the numbers in the ( ) are the same.

New:

x(x + 5) l +12(x+5)

Answer: (x+12)(x+5)

The probability that a mature hen will lay an egg on a given day is 0.80. Hannah has 12 hens. What is the probability that 10 of

OleMash [197]

Answer: 0.28

Step-by-step explanation:

Binomial probability formula :

$P(X=x)=\ ^nC_xp^x(1-p)^x$ , where x = Number of success , n= sample size , p= probability of success for each trial.

Let x = Number of hens lay eggs.

then, p= 0.80

n= 12

For x=10

$P(x=10)=\ ^{12}C_{10}(0.80)^{10}(0.20)^{2}\\\\=\dfrac{12!}{10!2!}\times 0.1073741824\times 0.04\\\\\approx0.28$

Hence, the required probability = 0.28
