The local zoo welcomed a newborn African elephant that weighed 34 kg. It is expected that at adulthood, the newborn elephant will weigh approximately 34 times as much as its birth weight. What expression represents the expected adult weight of the newborn elephant? Explain why the Product of Powers Property makes mathematical sense.

Answer:

1. ∠A =  71.9°

2. ∠B =  62.9°

3. ∠C = 27.5°

Step-by-step explanation:

By using a calculator, we have;

cos A = 0.31

sin B = 0.89

tan C = 0.52

1. Therefore, ∠A = cos⁻¹(0.31), inputting the digits in the calculator and looking for the inverse sign, we have;

∠A = cos⁻¹(0.31) = 71.94° = 71.9° to the nearest tenth of a degree.

2. For sin B = 0.89, we have;

∠B = sin⁻¹0.89 = 62.873° ≈ 62.9° with the answer rounded to the nearest tenth of a degree.

3. Similarly, for tan C = 0.52, inputting the values in the calculator and pressing the tan⁻¹ button, we have;

∠C = tan⁻¹(0.52) = 27.474°, which is 27.5° rounded to the nearest tenth of a degree.

Answer: 20%

Step-by-step explanation: To write a fraction as a percent, first remember that a percent is a ratio of a number to 100.

So to write 1/5 as a percent, we need to find a fraction equivalent to 1/5 that has a 100 in the denominator.

We can do this by setting up a proportion.

[tex]So[/tex] [tex]we[/tex] [tex]have[/tex] [tex]\frac{1}{5} = \frac{n}{100}[/tex].

Now, we can use cross-products to find the missing value.

So we have (1)(100) which is 100 is equal to (5)(n) or 5n.

So we have 100 = 5n.

Next, dividing both sides of the equation by 5, we have 20 = n.

So 1/5 is equal to 20/100 or 20%

Answer:

4.8 dollars for 1 pound super nutty

Answer:

Final price f = 0.85x

Step-by-step explanation:

Let f represent the final price and

x is the original price of the lawn mower

Given;

The hardware store is having a 15% off sale on lawn mowers this weekend;

the final sales price,excluding tax will be equal to the original price minus 15% of the original price.

Final price f = 100% of x - 15% of x

Final price f = x - 0.15x

Final price f = 0.85x

Answer:

[tex]1.6[/tex]                                                                                 - written in [tex]2/12/2021[/tex]

Step-by-step explanation:

The answer is [tex]1.6[/tex] because, [tex]\frac{5+8+11+7+9}{5} = 8[/tex] and [tex]8-5=3[/tex], [tex]8-8=0[/tex], [tex]11-8=3[/tex], [tex]8-7=1[/tex], and [tex]9-8=1[/tex].

So use all the sums and you'll get this: [tex]\frac{3+0+3+1+1}{5} =1.6[/tex]

Answer:

36

Step-by-step explanation:

58 times 5 is 290. 290-254 is 36

Answer: - 63

Step-by-step explanation:

An arithmetic progression is such that the N-th element is equal to:

An = A1 + (n-1)*R

where A1 is the first term, and R is the difference between two consecutive terms.

We know that

A1 + 9*R = -37

and

A1 + (A1 + R) +  (A1 + 2R) +   (A1 + 3R) +  (A1 + 4R) +  (A1 + 5R) = -27

6*A1 + R(1 + 2 + 3 + 4 + 5) = -27

6*A1 + 15*R = -27

so we have two equations:

6*A1 + 15*R = -27

A1 + 9*R = -37

Let's find A1 and R.

First, isolate A1 in the second equation:

A1 = -37 - 9*R

now replace it in the other equation and solve it for R.

6*A1 + 15*R = -27

6*(-37 - 9*R) + 15*R = -27

-222 - 54*R + 15*R = -27

-39*R = -27 + 222 = 195

R = 195/-39 = -5

Now we can find the value of A1:

A1 = -37 - 9*R = -37 - 9*-5 = 8

So now we want to calculate the sum of the first eight terms. we already know that the sum of the first six is -27, so we need to add the seventh and the eigth.

A7 = 8 + 6*-5 = -17

A8 = 8 + 7*-5 = -22

Sum = -27 -17 - 22 = -63

Answer:

80

Step-by-step explanation:

An isosceles has 2 angles that are the same so 50+50 is 100 so we have 80 degrees left to make a full triangle because all angles will always add up to 180 so 50+50+80 is 180 degrees

Step-by-step explanation:

Answer:

~460032.8

Step-by-step explanation:

Essentially, when this is written out, we get:

6 ÷ 2 × 3 × 100 × 700 ÷ 1.37 × 0.778 + 0.778913 × 100 × 10 × 1.77 × 444444.47 ÷ 7777777.0999 + 100

Order of operations says to do multiplication and division first, so let's calculate 6 ÷ 2 × 3 × 100 × 700 ÷ 1.37 × 0.778 separately:

6 ÷ 2 = 3

3 × 3 = 9

9 × 100 = 900

900 × 700 = 630000

630000 ÷ 1.37 = 459854

459854 × 0.778 = 357766

Now calculate 0.778913 × 100 × 10 × 1.77 × 444444.47 ÷ 7777777.0999:

0.778913 × 100 × 10 × 1.77 × 444444.47 = 612744929

612744929 ÷ 7777777.0999 ≈ 78.78

Add these all up:

357766 + 78.78 + 100 ≈ 460032.8

Answer:

20622.58008

Step-by-step explanation:

6 divide by 2: 3

times 3: 9

times 100: 900

multiply by 700: 630000

divide by 1.37: 459854.0146

multiply by 0.778: 357766.4234

then add: 0.778913 × 100 × 10 × 1.77:

359145.0994

multiply by 444444.47: 1.5962 ×10¹¹

divide by 7777777.0999: 202522.58008

add 100: 20622.58008

Answer:

4

Step-by-step explanation:

Add 1/8 until, when simplified, it will equal 1/2:

1/8 + 1/8 = 2/8

2/8 + 1/8 = 3/8

3/8 + 1/8 = 4/8 = 1/2

4 1/8 are needed to get 1/2: (4 * 1)/8 = 4/8 = 1/2

Answer:

1.5 square feet will be entirely covered

Step-by-step explanation:

Firstly, let’s have an arbitrary value for the total area of a garden.

Let’s say the total garden has a measure of 80 square foot.

Now, 3/8 which is corresponding to 3/8 * 80 = 30 square foot was used to plant 1/4 packet of flower seeds.

To plant another 1/4, what will be required is another 30 square foot, to plant the third 1/4, what is required is another 30 square foot, to plant the last set of 1/4, what is required would be another 30 square foot

The total amount of square foot thus needed is 30 + 30 + 30 + 30 = 120 square foot

Now this fraction measures in decimal that of the initial total; 120/80 = 30/20 = 1.5 square feet

OR

we can have it as;

1/4 of packet covered 3/8 square feet

1 packet will cover x square feet

Mathematically;

x * 1/4 = 3/8 * 1

x = 3/8 divided by 1/4

x = 3/8 * 4 = 12/8 = 1.5 square feet

Answer:

Step-by-step explanation:

First, multiply 5 km by 7 (days). 5 × 7 = 35 km

Convert the kilometres to centimetres.

There are 100,000 cm in a kilometer, so multiply:

35 × 100,000 = 3,500,000 cm.

Answer:

y = 3x -5

Step-by-step explanation:

6x - 2y = 10

-6x. -6x

Inverse Operations

-2y = -6x + 10

÷-2. ÷-2. ÷-2

y = 3x - 5

Answer:

6x – 2y = 10

2x + 3y = 51

Solving the first equation above for y gives:

     y =        (3)     x – 5

Which choice shows the result of substituting

3x – 5 into the second equation for y?

2(3x – 5) + 3x = 51

----------2x + 3(3x – 5) = 51      its B

2(3x – 5) + 3y = 51

Solving the equation 2x + 3(3x – 5) = 51

for x gives x =

Answer:

Option given in the top right.

Step-by-step explanation:

If an acute triangle is rotated about a point,

- Angles of the transformed triangle remain unchanged.

If a triangle is dilated by a scale factor of [tex]\frac{1}{2}[/tex],

- Measure of sides of the image will be dilated by a scale factor of 0.5.

Therefore, statement that compares ΔABC to ΔA'B'C' will be,

The angle measures of the triangle A'B'C'are the same of those ΔABC, but the side length of the ΔA'B'C' half the size of those of ΔABC.

Option given in the top right is the answer.
