William was parasailing at about 900 feet in the air while a shark swam
directly below him at 30 feet below the surface of the ocean. How far is
William from the shark?*

Answer:

76  14/20

(76  7/10) simplified

Step-by-step explanation:

First we make the denominator of the fraction equal

82  15/20

24  16/20

18   15/20

We then subtract

82 15/20 -  24 16/20

81  35/20 - 24 16/20 =

57  19/20

Then we add

57  19/20 + 18 15/20=

76  14/20

(76  7/10) simplified

Step-by-step explanation:

Answer:

Answer is explained below in the explanation section.

Step-by-step explanation:

Solution:

For this question, we need to have a number line, we can not make the number line here. As it will be very long. Instead, I have attached a number line from -11 to +11 for your understanding and explained it below. Please refer to the attachment below for the number line.

Number Line:

A number line is a line which contains all the numbers from negative infinity to positive infinity divided by a single number zero. It has two sides, left hand side and right hand side. A side left to zero contains all the negative numbers and a side right to 0 contains, all the positive numbers.

So,

We are asked to add 34 in (-212), we will get 178 but with the negative sign, and it will lie on the left hand side of the number line.

SO,

34 + (-212) = 34 - 212 = -178

Hence,

Our sum which is 178 will lie on the left hand side of the number line.

Answer:

one forty fifth times five equals one ninth

Step-by-step explanation:

In division, the number being divided is the dividend or numerator, the denominator is the number we use to do the division while the result is the quotient and there may be a reminder.

For example, if

a/b = c

then

a = b * c

hence

1/9  ÷ 5

= 1/9 * 1/5

= 1/45

This means that

1/45 * 5 = 1/9

Hence the related multiplication equation related to the division equation one ninth ÷ 5 is one forty fifth times five equals one ninth

Division expression are the expression in which one number is divided by other. Multiplication equation is related to the division equation one ninth divided by five is one forty fifth times five equals one ninth. Thus the option 2 is the correct option.

The given division equation is the fraction 1/9 divided by the number 5. That is,

[tex]\dfrac{\dfrac{1}{9} }{5} =\dfrac{1}{45} [/tex]

Division expression are the expression in which one number is divided by other

1) Five times one twenty fifth equals one ninth-This can be written as,

[tex]5\times \dfrac{1}{25} =\dfrac{5}{25} [/tex]

[tex]5\times \dfrac{1}{25} =\dfrac{1}{5} [/tex]

Which is not equal to the the given division expression.

2) One forty fifth times five equals one ninth-This can be written as,

[tex]\dfrac{1}{45}\times5 =\dfrac{1}{9} [/tex]

This is equal to the the given division expression.

3) One forty fifth times one fifth equals one ninth-This can be written as,

[tex] \dfrac{1}{45}\times\dfrac{1}{5} =\dfrac{1}{225} [/tex]

Which is not equal to the the given division expression.

4) Five times one fifteenth equals one ninth-This can be written as,

[tex]5\times \dfrac{1}{15} =\dfrac{1}{3} [/tex]

Which is not equal to the the given division expression.

Hence multiplication equation is related to the division equation one ninth divided by five is one forty fifth times five equals one ninth. Thus the option 2 is the correct option.

Answer:

Step-by-step explanation:

For 10 flapjacks we need a total of 100g of ingredients

therefore, we need to get how many gram for 1 flapjacks

that is, for butter 20÷10=2

for sugar 30÷10=3

for rolled oats 50÷10=5

that's a total of 10.

this means it takes 10g of ingredients to make 1 flapjacks

then 140+150+200=490

490÷10=49

The final answer is 49 flapjacks can be made from the above ingredients

Answer:

34.5%

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

[tex]\mu = 9, \sigma = 2.5[/tex]

What percentage of the books last more than 10 years?

As a proportion, this is 1 subtracted by the pvalue of Z when X = 10. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{10 - 9}{2.5}[/tex]

[tex]Z = 0.4[/tex]

[tex]Z = 0.4[/tex] has a pvalue of 0.655

1 - 0.655 = 0.345

So

34.5% of the books last more than 10 years.

Answer:

[tex] m\widehat {EF} = 146\degree [/tex]

Step-by-step explanation:

Measure of an arc is equal to the measure of its corresponding central angle.

Here, measure of the corresponding central angle of the arc EF is 146°

Therefore,

[tex]m\widehat {EF} = 146\degree [/tex]

Step-by-step explanation:

(a/b*b/c=1/2*3/4)(a/c=3/8)

Answer:

B:25°

Step-by-step explanation:

Now [tex]\angle ABC[/tex] gets bisected by [tex]BD[/tex].

[tex]\angle ABD=25^{\circ}[/tex]

Since, the angle is bisected, this means that the angle is split into two equal parts or the angle is halved.

We know that one of the angles is [tex]25^{\circ}[/tex] so the other angle has to be [tex]25^{\circ}[/tex] also.

Hence, the [tex]m\angle DBC=25^{\circ}[/tex].

The probability is ⁹/₆₄

Step-by-step explanation:

Given;

number of red marbles, R = 3

number of green marbles, G = 5

Total number of marbles, T = 8

The probability of choosing two red marbles in a row with replacement;

[tex]P(2 R) = P(R_1 \ n \ R_2)\\\\P(2 R) = \frac{3}{8} \ \times \ \frac{3}{8} \\\\P(2 R) = \frac{9}{64}[/tex]

Therefore, the probability of choosing two red marbles in a row with replacement is ⁹/₆₄

Step-by-step explanation:

The two lines around x is the absolute value symbol. Absolute value is how far away a number is from 0 on a number line. -10 is 10 points away from 0, so it is now 10.

y = 10 - 11

y = -1

Answer:

[tex]112\:\mathrm{m}[/tex]

Step-by-step explanation:

If you were to draw a diagram, you could form two similar triangles using the pole and the building (unsolvable otherwise). Since these triangles are similar, we can write the following proportion:

[tex]\frac{3.3}{1.4}=\frac{h}{47.5}[/tex], where [tex]h[/tex] is the height of the building.

Solving, we get:

[tex]h=\frac{47.5\cdot 3.3}{1.4},\\h\approx \fbox{$112\:\mathrm{m}$}[/tex] (rounded to the nearest meter as requested in the problem).
