Answer:
Step-by-step explanation:
By the Pythagorean Theorem we know
h^2=x^2+y^2 (where h is the hypotenuse and x and y are sides of a right triangle)
w^2+18^2=30^2
w^2=30^2-18^2
w^2=900-324
w^2=576
w=24 in
Christopher spent a total of 52.50 at a bookstore he purchased a calendar for 9 and three books that cost the same
Answer:
Cost of each book = 14.5
Step-by-step explanation:
Given:
Total amount spend = 52.50
Cost of calendar = 9
Number of books = 3
Assume;
Cost of each book = a
Find:
Cost of each book
Computation:
Total amount spend = Cost of calendar + Number of books(Cost of each book)
52.50 = 9 + 3(a)
Cost of each book = 14.5
The Ling family has 4 boxes of cereal. They ate 3/4 of the cereal during the week. Part A: Write an expression for 3/4 of 4 boxes of cereal
what is 40% off of $400.00
Answer:
$240
To find 40% of $400:
40% (or .4) • $400 = $160
**$160 is 40% of 400**
To find 40% **OFF** of $400:
$400 - $160 = $240
Find the solution to the system. Write your solution as an ordered pair (x,y) with no spaces, no solution, or infinitely many. x=2y-7 and 4x+y=71 *
Answer:
The solution is (15, 11) There is only one solution.
Step-by-step explanation:
Solve this system using substritution. In the second equation replace x with 2y - 7, obtaining:
4(2y - 7) + y = 71, which simplifies as follows:
8y - 28 + y = 71, or
9y = 99. then y must be 11. If y is 11, then x = 2y - 7, or x = 2(11) - 7 = 15
The solution is (15, 11) There is only one solution.
Calculate the area of the isosceles trapezium drawn below:
Answer:
the formula is :
area = 1/2(b1 + b2) x h
in this case it's :
area = 1/2(3 + b2)x 4
You will need the length of the lower base to solve it.

Factor the expression using the GCF. A. 2(4a + 8c) B. 4(2a + 4c) C. 8(a + 2c) D. 16( 12 a + c) Not multiple choice
Note: The expression is missing. Consider the expression is [tex]8a+16c[/tex].
Given:
The expression is
[tex]8a+16c[/tex]
To find:
Factor form of the given expression by using GCF.
Solution:
We have,
[tex]8a+16c[/tex]
Factors of each term:
[tex]8a=2\times 2\times 2\times a[/tex]
[tex]16c=2\times 2\times 2\times 2\times c[/tex]
The common factors are 2, 2 and 2. So,
[tex]GCF(8a+16c)=2\times 2\times 2[/tex]
[tex]GCF(8a+16c)=8[/tex]
Taking out the greater common factor (GCF) in the given expression, we get
[tex]8a+16c=8(a+2c)[/tex]
Therefore, the required expression is [tex]8(a+2c)[/tex] and the correct option is C.

Answer:
Row 1
Step-by-step explanation:
If you divide the number of oranges in each row by their number of boxes, you always get 13 oranges per box.
(156/12 = 13)
(130/10 = 13)
(91/7 = 13)
(65/5 = 13)
But, in Row 1, he made a mistake: 13/2 = 6.5 The mistake here is that Row 1's "number of boxes" should be 1, not 2, to make this eqation true. If we did this, then we will get 13 as our "number of oranges" instead of 6.5, becuase the equation will now be 13/1 = 13 and his table will be correct.
Row 1 has the mistake.

Find the 8th term of the geometric sequence 6, 18, 54, ...
Answer:
13122
Step-by-step explanation:
6 x 3 = 18; 18 x 3 = 54; continue to do this 8 times and you get 13122!
Answer:
a(8) = 6*3^7 = 13122
Step-by-step explanation:
Each new term is equal to the previous one times the common ratio, r, which in this case is 3.
The general formula for a geometric sequence is a(n) = a(1)*r^(n - 1).
In this particular case, we have a(n) = 6*(3)^(n -1).
The 8th term of this sequence is a(8) = 6(3)^(8 - 1), which works out to:
a(8) = 6*3^7 = 13122
What do I do!! mike cuts 4 equal pieces. What is the angle measure of each piece? Write and solve the equation
Question:
Mike cut a round pizza into 4 equal pieces. What is the angle measure of each piece?
Answer:
[tex]Angle = 90[/tex]
Step-by-step explanation:
Given
Round pizza
[tex]Pieces = 4[/tex]
Required
Angle measure of each
In a round object, the total angle is 360.
So, the angle of each piece is calculated by dividing 360 by the number of pieces (4)
So, we have:
[tex]Angle = 360/4[/tex]
[tex]Angle = 90[/tex]
