could someone please help me with 20.7 divided by 1.5

Answers

Answer 1

Answer:

13.8

Step-by-step explanation:

First, lets convert to fraction

20.7 = 207/ 10

1.5 = 15/10

therefore,

20.7 / 1.5 becomes;

(207/10) / (15/10)

this becomes;

(207/10) * (10/15)

10 cancels out

= 207/15

Divide both numerator and denominator by 3

=69/5

=13.8

In a 45-45-90 triangle, the ratio of the length of the hypotenuse to the length of a side is

Answers

Explanation:

See the figure below for a better understanding of the problem. Since we have a 45-45-90 triangle, this is an isosceles triangle, so both the adjacent and opposite sides measure the same value, say, x. Then the hypotenuse would be:

[tex]H=\sqrt{x^2+x^2} \\ \\ H=2\sqrt{2}[/tex]

Then. the ratio of the length of the hypotenuse to the length of a side is:

[tex]\boxed{r=\frac{2\sqrt{x}}{x}}[/tex]

In a 45-45-90 triangle, the ratio of the length of the hypotenuse to the length of a side is √2:1. This means that if one of the legs (the sides opposite the 45-degree angles) has a length of "x" units, then the hypotenuse (the side opposite the 90-degree angle) will have a length of "x√2" units.

PLEASE HELP - Part A Find the value of x in the following figure: Part B Find the measure of ACD

Answers

Answer:

Part A = 90

Part B = 145

Step-by-step explanation:

For part A, we know that a triangle has a sum of 180 degrees. So we just add the angles we already know and then subtract them from 180. For part B, we know that angle ACB and angle ACD are supplementary angles, meaning they add up to 180 degrees. So just take 180 and subtract 35 to find the measure of angle ACD.

If 12 and 20 each divide K without a remainder, what is the value of K?

Answers

Factors of 12 : 1, 2, 3, 4, 6, 12

Factors of 20: 1, 2, 4, 5, 10, 20

In both lists of factors, 4 is in common. Therefore, the value of K is 4 because it can divide into both 12 and 20 without a remainder. 2 is also another possible value of K.

Answer:

4

Step-by-step explanation:

1*12=12   1*20=20

2*6=12   2*10=20

3*4=12   4*5=20

both have a similar multiple of 4, so k must be 4.

Find the slope of the line that contains the points (1,-1) and (-2,8)

Answers

The formula for slope is (y-y1)/(x-x1).
1 = x
-1 = y
-2 = x2
8 = y2

You would plug those into the formula: (-1-(-2))/(-1-8) and that would equal to: 1/(-9).

The slope of the line that contains the points (1,-1) and (-2,8) is calculated using the change in y-values over the change in x-values, which results in a slope of -3.

To find the slope of the line that contains the points (1,-1) and (-2,8), we use the formula:

slope (m) = (Change in y) / (Change in x) = (y2 - y1) / (x2 - x1)

Substitute the given points into the formula:

m = (8 - (-1)) / (-2 - 1)
= (8 + 1) / (-2 - 1)
= 9 / (-3)
= -3

So, the slope of the line is -3.

The difference in length between a monarch butterfly and a bumblebee greater than the difference in length between a walking stick and grasshopper.

Solution:

Length of Monarch butterfly = [tex]3\frac{1}{2}[/tex] in

Length of Bumble bee = [tex]\frac{5}{8}[/tex] in

Difference between their lengths

                                   [tex]=3\frac{1}{2}-\frac{5}{8}[/tex]

To convert mixed fraction into improper fraction.

                                    [tex]=\frac{7}{2}-\frac{5}{8}[/tex]

To make the denominator same, multiply and divide the first term by 4.

                                    [tex]=\frac{28}{8}-\frac{5}{8}[/tex]

                                   [tex]=\frac{23}{8}[/tex]

Difference between length of Monarchy and Bumble bee is [tex]\frac{23}{8}[/tex] in.

Length of Walking stick = 4 in

Length of Grasshopper = [tex]1\frac{3}{4}[/tex] in

Difference between their lengths

                                   [tex]=4-1\frac{3}{4}[/tex]

To convert mixed fraction into improper fraction.

                                    [tex]=\frac{4}{1}-\frac{7}{4}[/tex]

To make the denominator same, multiply and divide the first term by 4.

                                    [tex]=\frac{16}{4}-\frac{7}{4}[/tex]

                                   [tex]=\frac{9}{4}[/tex]

Difference between length of Walking stick and Grasshopper is [tex]\frac{9}{4}[/tex] in.

Compare: [tex]\frac{23}{8}[/tex] and [tex]\frac{9}{4}[/tex]

To compare the fractions, make the denominator same.

So multiply and divide [tex]\frac{9}{4}[/tex] by 2, we get

[tex]\frac{23}{8}[/tex] and [tex]\frac{18}{8}[/tex]

[tex]$\frac{23}{8}>\frac{18}{8}[/tex]

Hence the difference in length between a monarch butterfly and a bumblebee greater than the difference in length between a walking stick and grasshopper.

Each side of a square is increasing at a rate of 8 cm/s. At what rate is the area of the square increasing when the area of the square is 25 cm2?

Answers

Answer:

80cm^2/s

Step-by-step explanation:

This is a related rates problem where we are considering the rate at which the area of a square changes with respect to time.

So lets consider the area of a square:

A = s^2 (where s represents the length of one side of the square)

Related rates problem deal with functions of time so if we take the area and side length as a function of time and then differentiate implicitly we get:

[tex]\frac{dA}{dt} = 2s(\frac{ds}{dt})[/tex]

The problem states that the side of a square is increasing at a rate off 8cm/s so we can conclude that ds/dt = 8cm/s leaving us with:

[tex]\frac{dA}{dt} = 16s[/tex]

Now, to solve for s we have to consider the other value given. If the area of the square is initially 25cm^2 we can plug this into our formula for area to solve for the side length.

25 = s^2

s = +/- 5 (since side lengths are only positive we only consider +5)

s = 5

Now we can plug this back in for s:

[tex]\frac{dA}{dt} = 80[/tex]

Therefore, the rate at which the area of the square is increasing is 80cm^2 per second.

Christopher runs a farm stand that sells apples and bananas. Yesterday Christopher sold 35 pounds of apples and 34 pounds of bananas for a total revenue of $163.50. Today he sold 15 pounds of apples and 17 pounds of bananas for a total revenue of $76.75. Determine the price of each pound of apples and the price of each pound of bananas.

Answers

Answer:

Pound of Apples = 2$

Pound of Banana = 2.75$

Step-by-step explanation:

Data

Yesterday Christopher sold 35 pounds of apples (35A) and 34 pounds of bananas (34B) for a total revenue of $163.5 (=163.50)

Today he sold 15 pounds of apples (15A) and 17 pounds of bananas (17B) for a total revenue of $76.75. (=76.75)

Now well, we have a system of the equation

35A+34B=163.50

15A+17B=76.75

we must eliminate A or B,  As you can see 34 is twice 17, so we multiply on both sides of the equation so as not to alter it

35A+34B=163.50                35A+34B=163.50                            

15A+17B=76.75 (-2) ⇒        -30A-34B=-153.50

                                              5A-0B = 10

5A=10 ⇒ A=10/5 ⇒ A=2

and B:

35(2)+34B=163.5 ⇒ 70+34B=163.5 ⇒ 34B=163.5-70

34B=93.5 = 93.5/34

B=2.75

Let x represent the price of each pound of apples and y represent the price of each pound of bananas.

Since 35 pounds of apples and 34 pounds of bananas for a total revenue of $163.50. Hence:

35x + 34y = 163.50      (1)

Also, 15 pounds of apples and 17 pounds of bananas for a total revenue of $76.75. Hence:

15x + 17y = 76.75        (2)

Solving equations 1 and 2 simultaneously gives x = 2, y = 2.75

The price of each pound of apples is $2 while price of each pound of banana is $2.75

The shape is way too complicated by itself, so I cut the shape into 5 different parts.

Please refer to the attached image or my answer will not make much sense.

Shape 1:

This is a triangle. The base is 3 and the height is 2. Thus, the area is:

[tex]A=\dfrac{1}{2}*3*2[/tex]

[tex]=3[/tex]

Shape 1 has an area of 3 square units.

Shape 2:

This shape is also a triangle. The base is 4 and the height is 2. Thus, the area is:

[tex]A=\dfrac{1}{2}*4*2[/tex]

[tex]=4[/tex]

Shape 2 has an area of 4 square units.

Shape 3:

This a unit square (the side lengths are 1).

Thus, Shape 3 has an area of 1 square unit.

Shape 4:

This shape is a rectangle. The base is 3 and the height is 4. Thus, the area is:

[tex]A=3*4[/tex]

[tex]=12[/tex]

Shape 4 has an area of 12 square units.

Shape 5:

This shape is also a rectangle. The base is 4 and the height is 2. Thus, the area is:

[tex]A=4*2[/tex]

[tex]=8[/tex]

Shape 5 has an area of 8 square units.

Total shape:

Add the areas of all 5 shapes to find the area of the shaded figure.

[tex]A=3+4+1+12+8[/tex]

Chuck mallory makes a deposit at an atm and walks away with $50.00 in cash and the receipt for the $538.00 total deposit he made. He remembers that the checks deposited totaled twice the currency he deposited. He did not deposit any coins. How much In currency did he deposit ? How much in checks did he deposit ?

Answers

Final answer:

Chuck Mallory deposited $179.33 in currency and $358.66 in checks at an ATM. This total transaction totaled $538.00.

Explanation:

The question references a deposit made at an ATM. We'll analyze this transaction with the given facts.

Chuck deposited a total of $538.00 He left the bank with $50.00 in cash The total deposit is composed of checks and currency The checks deposited were twice the amount of currency deposited

Let's declare two variables to solve this problem. Let C represent the Currency and Ch represent the Checks. Based on the facts, we can establish the following equations:

C + Ch = $538 Ch = 2C

We can solve for C by replacing Ch in the first equation with 2C from the second equation. Doing this, we get C + 2C = $538, or 3C = $538.

By dividing both sides of the equation by 3, We get C = $179.33. He deposited $179.33 in currency.

We can then find how much in checks he deposited by substituting C=$179.33 in the second equation. Ch = 2* $179.33, so Ch = $358.66. He deposited $358.66 in checks.
