Which equation best represents the graph?

Answers

Answer:

The third one

Step-by-step explanation:

The graphs in the reversed shape of a cup are the graphs of quadratic equations whose coefficient of

x^2 is negative.

So, the answer must be either the first or the third.

It can be seen that when x= -4, y becomes 5.

Substituting the value of x, the third equation gives the value 5.

So, the answer is the third one.

What is the missing term? What is the rule? 8 9/10, 7 7/10, 6 1/2 , _________

Answers

Answer:

5 3/10

Step-by-step explanation:

You subtract 1 1/5 from the number (n).

(In equation) x = n - 1 1/5

5 3/10

The rule is to subtract 1 2/10 each time

To figure this out, first look at the whole numbers

8, 7, 6, ___

You can see that your subtracting one to get to the next number.

Now look at the fractions.

9/10, 7/10, 1/2

To figure out the change you want all the fractions to have the same denominator.

1/2 = 5/10

9/10, 7/10, 5/10, ___

You can now also see that 2/10 is being subtracted each term.

Adding the two changes you get 1 + 2/10 = 1 2/10

Two shops, Lidal and Oldi, sell the same brand of toilet rolls but with different package sizes. Calculate the price per 36 rolls for each shop.

Answers

Answer:

The answer is below

Step-by-step explanation:

At Lidal shop, 4 toilet rolls is sold for £2.40. Therefore the cost of each toilet roll is given as:

Cost of each roll at Lidal = £2.40 / 4 = £0.60 per roll

Cost of 36 rolls = cost for each roll * 36 rolls = £0.60 per roll * 36 rolls = £21.6

At Oldi shop, 9 toilet rolls is sold for £4.68. Therefore the cost of each toilet roll is given as:

Cost of each roll at Oldi = £4.68 / 9 = £0.52 per roll

Cost of 36 rolls = cost for each roll * 36 rolls = £0.52 per roll * 36 rolls = £18.72

When Josh and Sean were each 5 years old, Josh was 1.5 inches taller than Sean. Josh grew at an average rate of 2.75 inches per year from the time that he was 5 years old until the time he was 13 years old. Josh was 63 inches tall when he was 13 years old. How tall was Sean when he was 5 years old?

A. 39.5 inches
B. 42.5 inches
C. 44.75 inches
D. 47.75 inches

Answers

Step-by-step explanation:

josh is 1.5 inches taller than sean

so, let sean's height be x

sean = x

josh = x + 1.5

each year josh gain 2.75 inches, and now he's 13 so how many year has passed

13 y - 5 y = 8

then how tall he grew

2.75×8=22

x + 1.5+22=63

x=63-22-1.5

x=39.5

an element with mass 630 grams decays by 18.8% per minute. How much of the element is remaining after 7 minutes, to the nearest 10th of a gram?

Total Depreciation: 60.24%

What is exponential decay?

An exponential function's curve is created by a pattern of data called exponential decay, which exhibits higher decreases over time.

The exponential decay function:

Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.

Given:

An element with mass 630 grams decays by 18.8% per minute.

That means, 18.8% = 0.188

Here, we will use the exponential decay function.

Aₙ = A₀(1-r)ˣ, where y = Final amount, A₀ = Initial amount, r = Rate of decay in decimal form, x = Time.

Here,

A₀ = 630 grams

r = 0.188

x = 7 minutes

Substituting the values to the formula,

A₇ = 630(1-0.188)⁷

A₇ = 630(0.812)⁷

A₇ = 630(0.23275134787)

A₇ = 146.633

A₇ = 146.6 grams.

Therefore, element is remaining 146.6 grams.

The crispy rice treats have cooled, Mrs. Williams cuts them into 30 equal pieces. She gives two-fifths of the treats to her son and takes the rest to school. How many treats will Mrs. Williams take to school?

Answers

Answer:

18 pieces

Step-by-step explanation:

divide 30 by 5

you'll get 6

so one-fifth is equivalent to 6 of the pieces

multiply 6 by 2

you'll have 2 so two-fifths is equal to 12 pieces of rice crispy treats

subtract 12 from 30

30 - 12 = 18

So she took 18 pieces to school.
