Clyde’s age is 8 years more than thrice bonnie’s age. If the product of their ages is 80, how old is Clyde

Mathematics
1 answer:
Law Incorporation [45]3 years ago
6 0

Answer:

20

Step-by-step explanation:

Let Bonnie's age = b.

Clyde's age is 8 year more than Bonnie's age, so Clyde's age is

3b + 8

The product of the ages is 80, so

b(3b + 8) = 80

3b^2 + 8b = 80

3b^2 + 8b - 80 = 0

(3b + 20)(b - 4) = 0

3b + 20 = 0 or b - 4 = 0

3b = -20 or b = 4

b = -20/3 or b = 4

Discard the negative answer since an age is not a negative number.

Bonnie's age is 4.

Clyde's age is 3 * 4 + 8 = 12 + 8 = 20.

Answer: Clyde's age is 20.

In the expression 4 to the power of 9, the number 9 is called the D. exponent.
Number four here is the base, and the exponent is always shown as a superscript to the right of the base. It shows how many times you are supposed to multiply the base by itself.

A department store, on average, has daily sales of 28,651.79. the standard deviation pf sales is $1000. On Tuesday, the store so
adelina 88 [10]

Answer:

Tuesday's Z-score is 7.56

Step-by-step explanation:

We are given that a department store, on average, has daily sales of 28,651.79 and the standard deviation of sales is $1000.

Also, it is given that on Tuesday, the store sold $36,211.08 worth of goods.

Let X = Daily sales of goods

So, X ~ N(\mu = 28,651.79, \sigma^{2} =1000^{2})

The z-score probability distribution is given by;

        Z = \frac{X-\mu}{\sigma} ~ standard normal N(0,1)

Now, Tuesday,s Z-score is given by;

      Z = \frac{36,211.08-28,651.79}{1000} = 7.56

Yes, Tuesday was an unusually good day as on this day more worth of sales takes place as compared to the average daily sales of $28,651.79 .

Please help me this is important
Dmitrij [34]

Answer:

C. II, III, and IV only

Step-by-step explanation:

Lol I haven't done one of these in a while, so thanks for the practice!

It's important to note that a dilation does NOT change the angles of the shape whatsoever. By this, you know that II and III are automatically correct, which rules out A and B. After that, you can look at I, which is the only difference between C and D. Since the dilation factor is 2/3, the parallelogram you see is smaller than the original. Since in I, the original would be larger than the denominator, the correct answer would be at least greater than one (to be precise, it'd be 3/2). To make everything easier, you can find the value by assigning the original side a value of 1, which would make the prime value 2/3. 1/(2/3) is going to be 3/2.
