Three of the angles of a quadrilateral are 120° 48° and 92° what is the size of the fourth angle

Answers

Answer 1

360-120-48-92=100°

Each quadrilateral has 360° so simply deduct the angles to get your result.

Answer 2

Hi there! A quadrilateral has angles that add up to 360°. So we have the measurements of the first three angles. We will look for the 4th angle by solving. Let's add the totals of the first 3 angles. 120 + 48 + 92 is 260. Now, we subtract that number from 360. 360 - 260 is 100. There. The measurement of the fourth angle is 100°.

Ella used 1/4 yard of red ribbon. Fill in each box with a number from the list to show equivalent fractions for 1/4

Answers

While you do not have your choices listed, equivalent fractions to 1/4 could be:

2/8; 3/12; 4/16; 5/20; 6/24; etc.

To find equivalent fractions, we multiply the numerator and denominator by the same number.

Answer:

To find fractions equivalent to a given fraction, the process of amplifying the numerator and the denominator of that fraction must be performed. Specifically, each element is amplified by multiplying it by a positive integer. Thus, fractions equivalent to 1/4 are:

(1x2) / (4x2) = 2/8

(1x3) / (4x3) = 3/12

(1x4) / (4x4) = 4/16

(1x5) / (4x5) = 5/20

(1x6) / (4x6) = 6/24 ... Successively.

8 students can ride in each van. How many vans are needed for 29 students?

Answers

5. the bus number 5 wont be completely full of students.

There is the need for 4 vans.

To determine how many vans are needed for 29 students, with each van able to transport 8 students, we can use division and then round up, since you can't have a fraction of a van. We divide 29 students by 8 students per van, which gives us 3.625. Since we can't have 0.625 of a van, we need to round up to the next whole number to ensure all students have a seat. That means we need 4 vans to transport 29 students.

Divide the total number of students by the number of students each van can hold: 29 / 8 = 3.625.

Round this number up to the nearest whole number, because you need whole vans: This gives us 4.

Thus, you need 4 vans to transport 29 students.

How many ways are there to pick 8 balls from large piles of (identical) red, white, and blue balls plus 1 pink ball, 1 lavender ball, and 1 tan ball?

Answers

Suppose order does not matter, then combinations will consist of 0 to 3 of the singleton colors, and 5 to 8 that are some combination of red, white or blue. This implies that we shall formulate the answer as the sum from k=0 to k=3 of:
N=(Number of ways to pick k of the single colors)*(number of ways to pick 8-k balls from red, white pr blue)
The first factor is C(3,k), let's call the second factor A(8-k), where A(n) is the number of combinations or red, white or blue when n balls are selected. Given that we want to express A(n) as a formula in terms of n, let's say there are r red balls in a combination (0≤r≤n). Then there are (n-r) balls that are either white or blue that have been left over. Thus, the number of white balls must be integer from 0 to (n-r), for the universe of (n-r+1) possibilities. Hence, the rest are blue in exactly one way, so A(n) is the sum over r=0 to n:

A(n)=∑(1+n-r)
A(n)=(n+1)(n+1)-n(n+1)2
=(n+1)(2n+2-n)/2
=(n+1)(n+2)/2

thus
A(5)=6*7/2=21
A(6)=7*8/2=28
A(7)=8*9/2=36
A(8)=9*10/2=45

The total will give:
N=C(3,0)*A(8)+C(3,1)*A(7)+C(3,2)*A(6)+C(3,3)*A(5)
N=1*45+3*36+3*28+1*21=258

The answer is 258

The line plot shows the measurement of a certain liquid (in milliliters) in nine beakers. If you combined the liquids and then put an equal amount of liquid in each beaker, how much liquid would be in each beaker?
A)
1/8 ml

B)
1/2 ml

C)
7/29 ml

D)
1/4 ml

Answers

There would be 1/2 mL in each beaker.

We start by adding the amounts given by the line plot:
1/4 + 1/4 + 3/8 + 3/8 + 1/2 + 1/2 + 5/8 + 3/4 + 7/8

Find a common denominator. The smallest thing that 2, 4 and 8 will all evenly divide into is 8:

2/8 + 2/8 + 3/8 + 3/8 + 4/8 + 4/8 + 5/8 + 6/8 + 7/8

Add the numerators:
36/8

Now we divide this by 9:
36/8 ÷ 9 = 36/8 ÷ 9/1 = 36/8 × 1/9 = 36/72 = 1/2

All sides are the same, and all angles are the same.

Hello,

The answer should be option B "a parallelogram with all sides equal and all angles equal".

Reason:

The answer is option B because a square is a parallelogram with all sides and angles equal. Its not option A because a square is not a polygon but does have equal sides. Its also not option C because a square is a rectangle but not a trapezoid therefore not combined. Its also not option D because its not a polygon but does have four sides which saying there not equal therefore not the answer.

The perimeter of a rectangle is 80 feet. Find the demensions if the length is 5 feet longer than four times the width. Then find the area of the rectangle.
-Show All Work!-

Answers

Hey there!

The first thing we should do is review the formulas for area and perimeter.
Perimeter can be expressed in two ways: a) l+w+l+w OR b) 2l+2w.
The formula for area is: l*w

We know that the length is 5 feet longer than the width, so when we're defining our variables we can say that width is equal to 'w', and length is equal to 4w+5.
Since we know that the perimeter is equal to 80, we can say that [tex]80= 2(4w+5) + 2(w)[/tex].

Now all we have to do is combine like terms and solve for 80:

[tex]80 = 2(4w+5) +2w [/tex]
[tex]80 = 8w + 10 +2w[/tex]
[tex]80 = 10w +10[/tex]
[tex]80-10 = 10w +10 -10[/tex]
[tex]70 = 10w[/tex]
[tex] \frac{70}{10} = \frac{10w}{10} [/tex]
[tex]7 = w[/tex]

We now know that the width is equal to 7 feet. To find the length, we can substitute the width into 4w+5:
[tex]l = 4w + 5 = 4(7)+5[/tex]
[tex]l = 28 + 5[/tex]
[tex]l = 33[/tex]

Now we know that the length is equal to 33 feet.

So there's your dimensions: 7ft by 33 ft.

Next, to find the area, we take l*w
[tex]33*7 = 231ft^{2} [/tex]

Hope this is helpful! If any of this doesn't make sense or there's more I can help with, please let me know!

Billy is creating a rectangular patio in his backyard using square cement tiles. The length of the patio, in feet, is represented by the function l(x) = x + 5, and the width of the patio is represented by the function w(x) = x + 3. Write the standard form of the function which describes the total area of the patio, a(x) in terms of x, the side length of each tile.

Answers

The area of a rectangle by definition is given by:
a = (l) * (w)
Where,
w: width
l: long
Substituting the values we have:
a (x) = (x + 5) * (x + 3)
Rewriting:
a (x) = (x ^ 2 + 3x + 5x + 15)
a (x) = x ^ 2 + 8x + 15
Answer:
The standard form of the function which describes the total area of the patio, a (x) in terms of x is:
a (x) = x ^ 2 + 8x + 15

To find the function for the total area of Billy's patio, a(x), we multiply the length function, l(x) = x + 5, by the width function, w(x) = x + 3. Expanding this multiplication gives us the standard form a(x) = x² + 8x + 15.

Billy is creating a rectangular patio in his backyard using square cement tiles. The function for the length of the patio is l(x) = x + 5, and the function for the width is w(x) = x + 3. To find the function that describes the total area of the patio, a(x), in terms of x, we can multiply the length function by the width function.

First, let's define the area of a rectangle as the product of its length and width: a = l x w. Substituting our functions in, we get:

a(x) = (x + 5) x (x + 3)

Now we will expand this to write it in standard form:

a(x) = x² + 3x + 5x + 15
a(x) = x² + 8x + 15

Therefore, the standard form of the function describing the total area of the patio in terms of x, the side length of each tile, is a(x) = x² + 8x + 15.

Final answer:

To solve the complex expression involving negative numbers, the order of operations must be followed, dealing with the innermost brackets first and proceeding outward to determine the final answer is 1.

Explanation:

The expression given by the student is a mathematical expression involving negative numbers and the order of operations. To solve the expression (−4)−(−2)–{(−5)–[(−7)+(−3)–(−8)]}, we need to follow the order of operations, also known as PEMDAS or BODMAS, which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

Start by solving the innermost brackets: (−7) + (−3) – (−8) = −10 – (−8) = −2.Next, address the curly brackets by subtracting the result from step 1 from (−5): (−5) – (−2) = −3.Finally, solve the outermost expression by subtracting (−2) from (−4) and then subtracting the result of step 2: (−4) − (−2) – (−3) = −2 – (−3) = 1.

Therefore, the final answer to the expression is 1.

which describes the correlation shown?

Answers

Answer:

The correlation that is shown in the scatter plot is:

Strong positive.

Step-by-step explanation:

From the scatter plot we see that with the increase of one variable the second variable also increases.

Hence, the association is positive.

Also, if we draw a trend line that best represents the scatter plot then not all the points will lie above the line but all the data points are either over the line or very close to the line this means that the correlation coefficient is close to 1 but not exactly equal to 1.

Hence, the correlation is:

Strong positive.

( For perfect positive all the data points should lie above that line i.e. correlation coefficient must be equal to 1)

Answer:

Option C) Strong positive

Step-by-step explanation:

Correlation

Correlation is a technique that help us to find or define a relationship between two variables. It is a measure of linear relationship between two quantities. A positive correlation means that an increase in one quantity leads to an increase in another quantity A negative correlation means with increase in one quantity the other quantity decreases.

Looking at the graph it could be said that the variables are strongly positively correlated as with a small increase in one variable, the other variable increases.

It is not a perfect positive relation as change in one variable does not lead to equal change in other variable.

It cannot be negative relation as well.

Five years ago, Tim’s mom was three times Tim’s age today. Now their combined ages are 45. How old is Tim’s mom today?

Answers

To solve this problem, you must name a variable, create expressions representing the parts of the problem, and then set up an equation.

Let Tim's age today be t. Since Tim's mom's age five years ago was 3 times Tim's current age, Tim's mom's current age is equal to 3t + 5.
Their ages are collectively 45, so Tim's age t and Tim's mom's age 3t + 5 must be equal to 45. Set up an equation and solve for the variable t.

45 = t + (3t + 5)
45 = t + 3t + 5
45 = 4t + 5
40 = 4t
10 = t

Tim is currently 10, and after plugging 10 for t into 3t + 5, we see that Tim's mom is 35.

Now let's check our work. Their combined ages are 45; 10 plus 35 is equal to 45, so that is correct. Further, addressing the "Five years ago, Tim's mom was three times Tim's age today" bit, we see that 10 - Tim's current age - times 3 is equal to 30, which would be Tim's mom's age 5 years ago.

Answer:
Today, Tim's mom is 35.

Answer:

35 years

Step-by-step explanation:

45 = t + (3t + 5)

45 = t + 3t + 5

45 = 4t + 5

40 = 4t

10 = t

A square pyramid has a base length of 6 inches and a height of 8 inches. What is the volume of this pyramid? Enter your answer in the box. in³

Answers

V = 1/3 a^2 h
V = 1/3(6^2)(8)
V = 1/3(36)(8)
V = 96 in^3

Final answer:

The volume of the square pyramid with a base length of 6 inches and a height of 8 inches is 96 cubic inches.

Explanation:

To find the volume of a square pyramid, you can use the formula V = (1/3) × base area × height, where the base area is the area of the square base. Since the base length is 6 inches, the area of the base is 6 in. × 6 in. = 36 in.². The height of the pyramid is 8 inches. So, the volume of the pyramid can be calculated as follows:

V = (1/3) × 36 in.² × 8 in. = 96 in.³

Therefore, the volume of the square pyramid is 96 cubic inches.
