Answer: 8999 leaves is left on tree

Step-by-step explanation:

Remember there are: 10 trunks

10 branches

10 twigs

10 leaves

On one deca tree

Therefore we have to find for :

Which is :

10 trunks × 10 branches = 100 branches

100 branches × 10 twigs = 1000 twigs

1000 twigs × 10 leaves = 10000 leaves

We find for the leaves.

1 trunk = 10 branches = 10 twigs =

10 leaves

1 * 10 * 10 * 10 = 1000 leaves

1000 + 1 = 1001 leaves were picked

10000 - 1001 = 8999 leaves are left on the tree

Answer:

The answer is C) $7.00

Answer: A $3.25

Step-by-step explanation:

Each pen cost 7pm. So 100 pens would have cost 7p x 100 = $7

She bought a box of hundred for $3.75

He actually saved:

7 - 3.75 = 3.25

Answer:

B.

Step-by-step explanation:

Causation is often confused with correlation because they are so similar. B would mean that pollution is caused from something (lets say greenhouse gases for example) which then results in more cases of heart disease.

Causation is when the first variable may bring the second into existence or may cause the incidence of the second variable to fluctuate. So, causation is the capacity of one variable to influence another. Which, would make B, a suitable candidate.

Answer:

25/8

Step-by-step explanation:

turn 3 into a fraction with the denominator (multiply by 8 to find the numerator)~ 24/8

add 1/8 to get 25/8

The fraction 3 1/8 when written as an improper fraction is 25/8

From the question, we have the following parameters that can be used in our computation:

Fraction =  3 1/8

When converted to an improper fraction, we have

Numerator = 3 * 8 + 1

Evaluate

Numerator = 25

The denominator remains the same

So, we have

Fraction =  25/8

Hence, the improper fraction is 25/8

Answer:

63 minutes or 1 hour 3 minutes

Step-by-step explanation:

We can use ratios to solve

18 minutes    x minutes

--------------- = --------------

2 bowls          7 bowls

Using cross products

18*7 = 2x

Divide by 2

18/2 *7 = x

63 minutes

Answer: 63 minutes or 1 hour and 3 minutes

Step-by-step explanation:

18 minutes is how long it takes to make 2 bowls. To find out how long it takes to make 1 bowl, divide by 2.

18 / 2 = 9

Now multiply that by 7 to find out how long it takes to make 7 bowls.

9 * 7 = 63

63 minutes

Answer:

Answer:

8 and 12

Step-by-step explanation:

find a pattern: +3, -2

the missing numbers are 8 and 12

Answer:

The numbers missing are 8 and 7.

Step-by-step explanation:

First you need to find a pattern in the numbers. You will notice that the pattern is add 3, subtract two. This is because, to get from 4 to 7, you add three, and to get from 7 to 5, you subtract 2.

When you apply that pattern, you find the missing numbers.

5(+3)=8, then 8(-2)=6, then 6(+3)=9, then 9-2=7, then 7(+3)=10

Answer:

The answer is given below

Step-by-step explanation:

The question is not complete. The correct question is:

A square based pyramid have a height of 30 cm and base of 10 cm. The The square based pyramid is cut horizontally at a height of 15cm to leave this frustum.

Answer:

The frustum would have a base of 10 cm and height of 15 cm. The lower base has a length of 10 cm. to calculate the upper base, we use the formula:

[tex]\frac{height\ of\ frustum}{height\ of \ pyramid}=\frac{base \of\ upper\ edge}{base \of\ lower\ edge}[/tex]

Substituting:

[tex]\frac{30}{15}=\frac{10}{b} \\ b=15*10/30=5[/tex]

The volume of the frustum is given by the formula:

[tex]V=\frac{h}{3}(A_1+A_2+\sqrt{A_1A_2} )[/tex]

Where h is the height of the frustum = 15 cm, A1 is the area of the lower base = 10 * 10 = 100 cm², A1 is the area of the upper base = 5 * 5 = 25 cm²

Substituting gives:

[tex]V=\frac{h}{3}(A_1+A_2+\sqrt{A_1A_2} )=\frac{15}{3}(100+25+\sqrt{100*25} )= 875\ cm^3[/tex]

Answer:

x = 28

Step-by-step explanation:

We can use ratios to solve

x           x+10

------ = -----------

42         42+15

Using cross products

42(x+10) = x(42+15)

42x+420 = 57x

Subtract 42x from each side

420 = 15x

Divide by 15

420/15 = x

28 =x

Answer:

f(x) = -7x³ + 6

g(x) = -2x⁴ + 10

(f - g)(x) = -7x³ + 6 + 2x⁴ - 10

= 2x⁴ - 7x³ - 4

(f - g)(-5) = 2(-5)⁴- 7(-5)³- 4

= 1250 + 875 - 4

= 2121

Answer:

D

Step-by-step explanation:

If two lines are perpendicular, the products of their slopes will be -1. Therefore, we're looking for a line with slope of -1/2. Let's check each answer:

A: 5 - 3 / (-2 - 3) = 2 / -5    

B: 6 - 5 / 6 - 5 = 1

C: 5 - 3 / 4 - 3 = 2

D: 4 - 3 / 3 - 5 = -1/2

The answer is D.

The line through points ( 3,4) ( 5,3) is perpendicular to the line l , Option D is the correct answer.

An equation of a straight line is y = mx+c , here m is the slope and c is the y intercept

m is determined by

[tex]\rm m = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]

It is given that line l has slope = 2

The line perpendicular to it will have a slope such that the product is -1

So , the line perpendicular to it should have the slope = -1/2

Slope of Option A is

5 - 3 / (-2 - 3) = 2 / -5    

Slope of Option B is

6 - 5 / 6 - 5 = 1

Slope of Option C is

5 - 3 / 4 - 3 = 2

Slope of Option D is

4 - 3 / 3 - 5 = -1/2

Therefore , The line through points ( 3,4) ( 5,3) is perpendicular to the line l , Option D is the correct answer.

[tex]8 - \frac{m}{n} + p^2 = 53[/tex]

Step-by-step explanation:

Given

[tex]8 - \frac{m}{n} + p^2[/tex]

[tex]m = 8[/tex]

[tex]n = 2[/tex]

[tex]p = 7[/tex]

Required

Evaluate

To solve this;

we simply substitute the values of m, n and p in the given expression

In other words; we replace m, n and p with their actual values;

[tex]8 - \frac{m}{n} + p^2[/tex]

becomes

[tex]8 - \frac{m}{n} + p^2 = 8 - \frac{8}{2} + 7^2[/tex]

Solve fraction

[tex]8 - \frac{m}{n} + p^2 = 8 - 4 + 7^2[/tex]

Take square of 7

[tex]8 - \frac{m}{n} + p^2 = 8 - 4 + 49[/tex]

Add result

[tex]8 - \frac{m}{n} + p^2 = 53[/tex]

The expression has been evaluated and the result of [tex]8 - \frac{m}{n} + p^2[/tex] is 53, provided that m = 8, n = 2 and p = 7

24 cm of wire

is  3 (3 + 1)  + 3(3 + 1)

= 3 x 4 + 3 x 4

The total in the account after 10 years would be: $14,190.68

Step-by-step explanation:

Recall the formula for continuous compounding:

[tex]A=P\,e^{r\,t}[/tex]

where "A" is the accrued value after t years (what we need to find), "P" is the principal invested (in our case $10,000), "r" is the interest rate in decimal form (in our case r = 0.035), and "t" is the time in years (in our case t = 10). Therefore the formula becomes:

[tex]A=P\,e^{r\,t}\\A=10000\,\,e^{0.035\,*\.10}\\A=14190.68[/tex]

Therefore the total in the account after 10 years would be: $14,190.68
