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.

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.

Answer:$48.09 please give brainliest!

Step-by-step explanation: you need to turn the percent to decimal so you move the decimal points to places to the right so the percent now is 0.25 so then you do 38.47 *0.25 =9.62 so then you add 9.62 +38.47 =48.09

Answer:

$9.62

Step-by-step explanation:

total cost= $38.47

tip            = 25% = [tex]\frac{25}{100}[/tex]

=> tip       = [tex]\frac{25}{100}[/tex] * $38.47

               ≈ $9.62 (to the nearest cent)

NOTE: the question is solely asking for the tip, therefore, there is no need to add the tip to the total.

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.

Answer: x=-9

Step-by-step explanation:

First, we want to isolate x by subtracting ten from both sides

4x=-36

Then divide by four to get:

X=-9

Answer:-6

Step-by-step explanation:

you'd want to subtract the ten and move it under the 26, adding to make a negative 36 then divide by 4 on both sides

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.

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

A central angle has the same measure as its arc.

Hey there!

Let's make a system of equations using x and y to find the two numbers.X is smaller and y will be larger.

x+y=98

y-4x=18

Now, let's solve the bottom equation for y so we can use substitution.

y=18+4x

Now we plug this into the first equation.

x+18+4x=98

5x+18=98

5x=80

x=16

Now, we plug this into the first equation to find y.

y=82.

So, the larger number is 82 and the smaller number is 16.

Answer:

2(s+10r)

Step-by-step explanation:

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.

The range of a set of values is the lowest and highest number of that data set.

First, lets put the numbers from least to greatest.

138, 142, 155, 165, 172, 193

Second, find the lowest and greatest number in the data set.

138 is the lowest and 193 is the highest number in the data set.

Therefore, 138 and 193 is the range.

Best of Luck!

Problem setup:

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]

[tex]=26[/tex]

The figure has a total area of 26 square units.

Side notes:

There is a way to solve this problem by only dividing this into only 3 different shapes, can you figure it out?

Let me know if you need a hint or any clarifications, thanks!

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

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

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:

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.

Answer:

(5 x + 2) (x + 2)

Step-by-step explanation:

Factor the following:

5 x^2 + 10 x + 2 x + 4

10 x + 2 x = 12 x:

5 x^2 + 12 x + 4

Factor the quadratic 5 x^2 + 12 x + 4. The coefficient of x^2 is 5 and the constant term is 4. The product of 5 and 4 is 20. The factors of 20 which sum to 12 are 2 and 10. So 5 x^2 + 12 x + 4 = 5 x^2 + 10 x + 2 x + 4 = 2 (5 x + 2) + x (5 x + 2):

2 (5 x + 2) + x (5 x + 2)

Factor 5 x + 2 from 2 (5 x + 2) + x (5 x + 2):
