Answer: A. 7.84

Step-by-step explanation:

1. According to the problem given in the image attached, the total energy used was 98 quadrillion Btu.

2. Therefore, if you want to know how many quadrillion Btu of energy were consumed in 2010 from renewable energy sources, you must multiply the percentage given in the circle graph, as following:

[tex]8[/tex]%[tex]=0.08[/tex]

Then:

[tex]98*0.08=7.84[/tex]

Answer:

2,000 problems

Step-by-step explanation:

We know the students solved the following amount of problems:

Week 1 - 25% of the month

Week 2 - 110% of the first week--> this means 25(1.10)=27.5%

Week 3 - 60% of the first two week--> this means 0.6(25+26.5)=31.5%

Week 4 - 320 problems --> this is 16% of the quota since 100-25-27.5-31.5=16%

So we know that 320 is 16%. We can set up a proportion to find the total amount.

[tex]\frac{16}{100} =\frac{320}{y}[/tex]

We solve by cross multiplying by multiplying numerator and denominator on opposite fractions.

[tex]16(y)=100(320)\\16y=32000\\\frac{16y}{16}=\frac{32000}{16}\\  y=2,000[/tex]

The quota for the month is 2,000 problems.

Answer:

Refer to the image attached

Step-by-step explanation:

The next number in the sequence 16, 4, 20, 24, 44 is 68 and in the sequence 6, 5, 15, 10, 70 is 61.

A sequence's series is the total number of terms in the sequence.

A series follows some pattern for example if you take data set of natural numbers then there will be a sequence of that data and something will be due to that we can form that series.

Now the given series are,

16, 4, 20, 24, 44

and 6, 5, 15, 10, 70

Now the difference between the two terms of the series 16, 4, 20, 24, 44

4 - 16 = 12 = 4*3

20 - 4 = 16 = 4*4

24- 20 = 4 = 4*1

44 - 24 = 20 = 4*5

So let x be the next term; hence it can be written as

x - 44 = 4*6

x = 24 + 44

x = 68

Now for the series 6, 5, 15, 10, 70, it is an alternative series,

6 - 1 = 5

5 x 3 = 15

15 - 5 = 10

10 x 7 = 70

So the next term is given as,

70 - 9 = 61

Hence, The next number in the sequence 16, 4, 20, 24, 44 is 68 and in the sequence 6, 5, 15, 10, 70 is 61.

Answer:

The jar of chermical contains 66g of Zinc.

Step-by-step explanation:

The ratio of Zinc to Copper is 3 : 13

A jar of the chemical contains 286g of copper.

Let the mass of the Zinc be xg.

[tex]\frac{13}{3}[/tex] = [tex]\frac{286}{x}[/tex]

x = [tex]\frac{3 × 286}{13}[/tex] = 66g

So the jar of chemical contains 66g of Zinc.

To determine the grams of zinc in a jar of a chemical with a zinc to copper ratio of 3 to 13 and 286 grams of copper present, calculate the value of one part in the ratio (286 grams / 13) and multiply by the number of parts of zinc (3), resulting in 66 grams of zinc.

The student wants to find out how many grams of zinc are in a jar of chemical, given that the ratio of zinc to copper is 3 to 13 and there are 286 grams of copper. To solve this, we can use the concept of ratios. The ratio of zinc to copper is 3:13, which means for every 3 parts of zinc, there are 13 parts of copper.

First, let's find the value of one 'part' in the ratio by dividing the total amount of copper (286 grams) by 13 parts:

1 part = 286 grams / 13 = 22 grams

Now, to find the amount of zinc, we multiple the number of zinc parts (3) by the weight of one part (22 grams):

Amount of zinc = 3 parts / 22 grams per part = 66 grams

So, the jar contains 66 grams of zinc.

Answer: The three sides are 14, 14, 20

===================================

x = length of the two equal sides

x+6 = length of the third longer side

add up the three lengths x, x, x+6. Set it equal to the perimeter 48. Solve for x

x+x+x+6 = 48

3x+6 = 48

3x+6-6 = 48-6 ... subtract 6 from both sides

3x = 42

3x/3 = 42/3 ... divide both sides by 3

x = 14

If x = 14, then x+6 = 14+6 = 20

The three sides are 14, 14, 20

We can check this by adding up the three sides 14+14+20 = 28+20 = 48 and we get the right perimeter.

Answer:

Step-by-step explanation:

The percentage of the number of milligrams and Carrie’s body anytime after they both have taken the medication is less than 100%.

Suppose a number is 'a'

Suppose another number is 'b'

We want to know how much percent of 'b' is 'a'.

Then, it is calculated as:

[tex]\dfrac{a}{b} \times 100[/tex]

(in percentage)

We are given that;

Carrie is prescribed 600 mg of a medication.

The medication decays at a rate of 40% per day.

Now,

Let's first find the amount of medication remaining in Carrie's body after taking the medication for 5 days:

m = 600(0.6)^5

m ≈ 86.18 mg

To find the percentage of the amount of medication in Carrie's body after 5 days compared to anytime after they both have taken the medication, we need to find the amount of medication in Carrie's body at any given time, t. We can use the same formula and substitute t for d:

m = 600(0.6)^t

Now, we can calculate the percentage of the amount of medication in Carrie's body after 5 days compared to any time after they both have taken the medication:

(m after 5 days / m at any time) x 100%

= (86.18 / 600(0.6)^t) x 100%

= (0.1436 / 0.6^t) x 100%

Since we don't know the exact value of t, we can't simplify this expression any further. However, we can make some observations:

As t increases, the denominator (0.6^t) gets smaller, so the fraction as a whole gets larger.

When t is very large, the fraction approaches 0, which means that the amount of medication in Carrie's body approaches 0, or she has eliminated all the medication from her body.

Therefore, we can conclude that the percentage of the amount of medication in Carrie's body after 5 days compared to any time after they both have taken the medication will be less than 100%,

Answer:

KJ = 6 , LW = 3 , KJ = 6

Step-by-step explanation:

Let LW be x then KJ be x + 3

In ΔKHJ and ΔLGW,

∠K = ∠L and ∠H = ∠G , So, by AA Similarity, [tex]\Delta KHJ \sim\Delta LGW[/tex]

Therefore,

[tex]\frac{8}{4}=\frac{x+3}{x} =\frac{HJ}{2.5}[/tex]

First taking,

[tex]\frac{8}{4}=\frac{x+3}{x}\\8\cdot x = 4\cdot x + 12\\4\cdot x=12\\x=3[/tex]

∴LW = 3 , KJ = 6

Now,

[tex]\frac{8}{4}=\frac{HJ}{2.5}[/tex]

⇒ HJ = 5

The unknown sides of the triangle KHJ and triangle LGW are HJ = 5, LW = 3, and KJ = 6 and this can be determined by using the given data.

Given :

Given that m∠K = m∠L, m∠H = m∠G, therefore, triangle △KHJ and △LGW are congruent to each other by AA similarity postulate.

To determine the unknown sides of the given triangles, first, let the unknown side LW be 'a' and the side KJ be 'a + 3'.

[tex]\rm \dfrac{8}{4}=\dfrac{a+3}{a}=\dfrac{HJ}{2.5}[/tex]  -----  (1)

[tex]2\times a = (a+3)\times 1[/tex]

2a = a + 3

a = 3

Put the value of 'a' in equation (1).

[tex]\rm \dfrac{3+3}{3}=\dfrac{HJ}{2.5}[/tex]

HJ = 5

If someone deposits Rs 40000 in a bank at the rate of 5% p.a. after paying 5% tax, the amount he will get after 4 years is Rs 47600.

How the amount is determined:

Principal amount (P) = Rs. 40000

Rate of interest (R) = 5% per annum

Time period (T) = 4 years

We can calculate the simple interest using the formula:

[tex]\text{Simple Interest} = \frac{{P \cdot R \cdot T}}{{100}}[/tex]

Plugging in the values:

[tex]\text{SI} = \frac{{40000 \times 5 \times 4}}{{100}}[/tex]

= Rs 8000

Total Income after 4 years = Principal + Interest

Total Income = 40000 + 8000 = Rs 48000

Income Tax on Interest: The income earner needs to pay 5% income tax on the interest earned

Tax to Pay = 5% of Rs 8000 = Rs 400

Final Amount Received after Tax = Total Income - Tax to Pay

= 48000 - 400

= Rs 47600

Answer:

50 lbs

Step-by-step explanation:

Jack picked 100 lbs of cranberries. If fresh cranberries have 99% of water, then in 100 lbs of cranberries there are 99 lbs of water and 1 lb of "cranberries".

After being dried this 1 lb of "cranberries" form 2% and the rest 98% is the water. Let the weight of the dried cranberries be x lbs, then

x lbs - 100 %,

1 lb - 2 %.

Therefore,

[tex]\dfrac{x}{1}=\dfrac{100}{2},\\ \\x=\dfrac{1\cdot 100}{2}=50\ lbs.[/tex]

The cranberries, starting at 100 lbs with 99% water content, will reduce to 50 lbs after drying, at which point they have 98% water content. The substance weight shouldn't change being 1 lb as only the water content has changed.

The subject of your question falls under the category of Mathematics, specifically in Percentage and Weight Change. Given that fresh cranberries have 99% water and you started with 100 lbs, then only 1% of this weight, or 1 lb, is non-water content. This is the weight of cranberries' substance that doesn't change during drying.

The partially dried cranberries are 98% water. So the question is 'What weight would give us 1 lb as 2% (100%-98%=2%) of this weight?' The answer is 1 lb divided by 2% (or 1lb/0.02) which gives us 50 lbs. So, the cranberries will weigh 50 lbs after drying.
