Answer:

[tex]30+0.09x[/tex]

Here, [tex]x[/tex] denotes number of frosting flowers

Step-by-step explanation:

Let [tex]x[/tex] denotes number of frosting flowers.

Amount charged by baker for each batch of cupcakes = $30

Amount charged for each frosting flower = $0.09

So,

Amount charged for [tex]x[/tex] frosting flowers = [tex]\$0.09x[/tex]

Therefore,

Total cost of a batch of cupcakes with frosting flowers = [tex]30+0.09x[/tex]

Answer:

D (J)

Step-by-step explanation:

y=4x is basically multiplying the x value by 4; 10*4 is 40, 20*4 is 80, and so on.

Answer:

2x(x+y)(x-y)

Step-by-step explanation:

Given the expression;

(x+y)² + 2(x+ y)(x- y) + (x– y)²

Factorize

(x+y)² + (x+ y)(x- y) +   (x+ y)(x- y) + (x– y)²

= (x+y)[x+y+(x-y)] +(x-y)[(x+y)+(x-y)]

= (x+y)(x-y)(x+y+(x-y))

= (x+y)(x-y)(x+y+x-y)

= (x+y)(x-y)(2x)

hence the expanded form is 2x(x+y)(x-y)

Answer:

y=67.7 Degrees

Step-by-step explanation:

You're given the opposite and adjacent sides to angle Y, so we use Tan to find the angle:

Tan(y)= 100/41

We then inverse tan to isolate y

y=tan^-1 100/41

y=67.7 Degrees

Complete question is;

A fair coin should land showing tails with a relative frequency of 50% in a long series of flips. Felicia read

that spinning-rather than flipping-a US penny on a flat surface is not fair, and that spinning a penny

makes it more likely to land showing tails. She spun her own penny 100 times to test this, and the penny

landed showing tails in 60% of the spins.

Let p represent the proportion of spins that this penny would land showing tails.

What are appropriate hypotheses for Connor's significance test?

A. H_0 : p = 50% H_1 : p > 60%

B. H_0: p = 50% H_1: p > 50%

C. H_0: p = 50% H_1: p < 50%

D. H_0 : p = 60% H_1 : p < 60%

Answer:

Option B is correct

Step-by-step explanation:

From the question it is clear that;

The population proportion is 50% because it is not associated with any sample size.

However, the sample size is 100 and the sample proportion from this 100 is 60%.

But we don't define our hypothesis based on the sample proportion.

Now we want to find the probability that spinning a penny makes it more likely to land showing tails.

Thus we define the hypothesis as;

Null hypothesis; H0 : p=50%

Alternative hypothesis; H1 : p>50%

Answer:

(n + 1) (5m + 4)

Step-by-step explanation:

⇒ (n + 1) (5m + 4)

⇒ 5mn + 4n + 5m + 4

⇒ 5mn + 5m + 4n + 4

Answer:

(n + 1)(5m + 4)

Step-by-step explanation:

Given

5mn + 5m + 4n + 4 ( factor the first/second terms and the third/fourth terms )

= 5m(n + 1) + 4(n + 1) ← factor out (n + 1) from each term

= (n + 1)(5m + 4)

Step-by-step explanation:

P = 8

Step-by-step explanation:

Given that P varies inversely with x then the equation relating them is

P = \frac{k}{x} ← k is the constant of variation

To find k use the condition P = 7 when x = 8 , then

7 = \frac{k}{8} ( multiply both sides by 8 )

56 = k

P = \frac{56}{x} ← equation of variation

When x = 7 , then

P = \frac{56}{7} = 8

Step-by-step explanation:

Answer:

18

Step-by-step explanation:

30 + 18 = 48

30 - 18 = 12

Both true, so our solution is correct.

The value of the larger number is 30 and the value of the smaller number is 18.

A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set in a consistent manner using digits or other symbols. In different numeral systems, the same sequence of symbols can represent different numbers.

Given that the sum of two numbers is 48. if the smaller number is subtracted from the larger the difference is 12. The two numbers will be calculated as,

x + y = 48

x - y = 12

________

2x = 60

x = 30

y = 30 - 12

y = 18

Therefore, the value of the larger number is 30 and the value of the smaller number is 18.

Answer:

GCF = 4.

Step-by-step explanation:

Find the prime factors:

48 = 2*2*2*2*3

244 = 2*2*61

The greatest common factor, the GCF) (picking out the common values) =

2 *2 = 4.

A really clever way of finding the GCF of 2 numbers is Euclid's algorithm. It can be used for very large numbers where it would be time consuming and/or rather difficult to find prime factors:

Given two whole numbers where a is greater than b, do the division a ÷ b = c with remainder R.

Replace a with b, replace b with R and repeat the division.

Repeat step 2 until R=0.

When R=0, the divisor, b, in the last equation is the greatest common factor.

So applying this to our problem:

244 / 48 = 5 remainder 4

Replacing a (244) with 48 and b (48) with R (4):-

48/4 = 12 remainder 0.

So the GCF is 4.

Answer:A he is correct because the inner circle is a dilation of the outer circle

Step-by-step explanation: just did the test

The statement "He is correct because the inner circle is a dilation of the outer circle" is the best explanation.

Dilation is the process of modifying the size of an item or form by reducing or expanding its dimensions according to specific scaling variables.

The radius of the inner circle is 2 units, while the radius of the outer circle is 5 units.

Since dilations provide similar figures because multiplying by the scale factor yields proportionate sides while keeping the angle measure and form constant.

Troy is accurate if he claims the two circles are similar.

Hence, the statement (A) "He is correct because the inner circle is a dilation of the outer circle" is the best explanation.
