Answer:
9.18 cm
Step-by-step explanation:
A pyramid is a three-dimensional object. The base of a pyramid is a polygon. the top and the base of a polygon forms a triangle.
for a rectangular pyramid, the base is a rectangle
The volume of a pyramid = 1/3 × (area of the rectangle x height)
Area of a rectangle = length x width
15 x w = 15w cm²
826 = 1/3 x (15w x 18)
multiply both sides of the equation by 3
15w x 18 = 2478
Divide both sides of the equation by 15 x 18
w = 9.18 cm
divide both sides by 10

A football team played 90 matches. They won 37 matches.
They drew 1/9 of their matches.
What fraction of their matches did they lose?
Answer: 44 matches
Step-by-step explanation:
Let's take the given information
They won 37 matches
1/9th of their matches resulted in a draw
1/9 out of 90 is 9
You can take 90/9 and you will get 9
Now let us add 37+9 and you get 47
Now take 90-47
44 Matches lost
22/45 or 44/90

Step-by-step explanation: subtract 6 from both sides to get 2z=1 divide both sides by 2, you get z = 1/2 check by inputting 1/2 for z
2(1/2)+6= 7
1/2 of 2 is 1
1+6=7
it checks out :)
Answer: z= 1/2

Lisa and Maria were baking oatmeal cookies. Lisa baked 24 cookies on Friday and 36 on Saturday. Maria baked the same amount of cookies that Lisa baked on Saturday. How many cookies did they bake altogether?
Answer:
96 cookies.
Step-by-step explanation:
I don't love the wording of the question, but here's what I see:
Lisa Friday: 24
Lisa Saturday: 36
Maria total: 36
Cookie total: 96
-----------------------------------------------------
I can't really tell from how the question is worded if Maria's total was the total of what Lisa made, and she did it all on Saturday, or if Maria baked Lisa's Saturday number of cookies.
If 96 is the wrong answer, then try:
Lisa Friday: 24
Lisa Saturday: 36
Maria total: 60
Cookie total: 120

Answer:
22123
Step-by-step explanation:
→ Find the multiplier
3% decrease = 0.97
→ Multiply the population by the multiplier which is to the power of years
30000 × 0.97¹⁰ = 22122.7 = 22123
A bag contains 5 white marbles and 30 blue marbles. If a representative sample contains 2 white marbles, then how many blue marbles would you expect it to contain? Explain. Because the ratio of white marbles to blue marbles is ▼ 6:5 6:1 5:6 1:6 in the population, the expected number of blue marbles is nothing times the number of white marbles in the representative sample. There should be nothing blue marbles.
Answer:
6:1
Step-by-step explanation:
Answer: 10
Step-by-step explanation:
The expected number of blue marbles in the representative sample is 10. This is because the ratio of white marbles to blue marbles in the population is 5:6, so for every 5 white marbles there are 6 blue marbles. Since the representative sample contains 2 white marbles, the expected number of blue marbles should be 6 times the number of white marbles, or 6 x 2 = 10.

The drama club is selling tickets to their play to raise money for the show's expenses. Each student ticket sells for $6 and each adult ticket sells for $11. The auditorium can hold at most 100 people. The drama club must make no less than $770 from ticket sales to cover the show's costs. If xx represents the number of student tickets sold and yy represents the number of adult tickets sold, write and solve a system of inequalities graphically and determine one possible solution.
Answer:
Im not really sure what the question is asking but the drama club could sell 70 adult tickes and 30 student tickes and they would make $950.
Step-by-step explanation:
Answer:
possible solution (10,80)
Step-by-step explanation:
Variable Definitions:
x=the number of student tickets sold
y= the number of adult tickets sold
“at most 100 people"→100 or fewer tickets
Therefore the total number of tickets sold, x+y, must be less than or equal to 100:
x+y≤100
“no less than $770"→$770 or more
Each student ticket sells for $6, so x student tickets will bring in 6x dollars. Each adult ticket sells for $11, so y adult tickets will bring in 11y dollars. Therefore, the total amount of revenue 6x+11y must be greater than or equal to $770:
6x+11y≥770
Solve each inequality for y:
x+y≤100
y≤−x+100
6x+11y≥770
11y≥770−6x
y≥ -6/11x+70
Graph y≤100−x by shading down and graph y≥-6/11x+70
by shading up
Solve for x solve for x
Answer:
15
Step-by-step explanation:
The sum of angles around a point is added up to 360°.
Accordingly,
4x - 2 + 9x + 6 + 8x - 5 + 46 = 360
Combine like terms.
21x + 45 = 360
Subtract 45 from both sides.
21x = 360 - 45
21x = 315
x = 15

Given Triangle ABC with FC=5, you want to find BF. First, find the value that y must have for the Triangle Proportionality Theorem to apply. Then describe more than one way to find BF, and find BF. The y value for the Triangle Proportionality Theorem to apply is ______. To find BF, you can use the ______ Formula with the coordinates of B and F l, or you use the Trianglr Proportionality Theorem. BF=
Answer:
Part A
y = 8
Part B
We can find BF by either;
a) Through Pythagoras theorem to find the length of a side in a right triangle
b) The known rate of change of the length of the line FC with height
Step-by-step explanation:
Part A
The given parameters are;
FC = 5
We are to find BF
By the triangle proportionality theorem, we have;
FC:BF = EC:AE
From the given draining we have;
C(10, 2), F(7, 6), B(5.5, y), E(4, 2), A(1, 2)
Points A, E and C are have the same y-coordinate values, therefore, we have;
EC = 10 - 4 = 6
AE = 4 - 1 = 3
Therefore, we have;
5/BF = 6/3 = 2
BF = 5/2 = 2.5
Using the formula for finding the distance between two points, we have;
BF = √((5.5 - 7)² + (y - 6)²)
BF² = 2.5² = (5.5 - 7)² + (y - 6)²
6.25 = 2.25 + (y - 6)²
6.25 - 2.25 = 4 = (y - 6)²
√4 = √(y - 6)² = (y - 6)
±2 = y - 6
y = 6 + 2 = 8, or y = 6 - 2 = 4
Given that from the diagram, y > 6, we have y = 8
Part B
a) To find BF we can use the Pythagoras's theorem given that we know the coordinates of B and F as follows;
BF = √((5.5 - 7)² + (8 - 6)²) = 2.5
b) Given that BF is on the same straight line as FC, BF can be found through the rate of change of the y-values with the length of the line
We can also find BF by using proportion of increase in 'Δy' to the length of the line BFC as follows;
From point C to point F, Δy = 6 - 2 = 4 and the length of the line FC = 5
Therefore, from point B to point F, Δy = 8 - 6 = 2, ∴ BF = 2 × 5/4 = 2.5
Janet has a 65 dollar budget to buy paper goods and plastic cutlery for an impromptu birthday party. She determines that the paper goods will cost 37.50 . How many sets of cutlery can she purchase if each set costs 0.75? (She cannot buy a partial set of cutlery.)
Janet can buy 36 sets of cutlery.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Janet has a 65 dollar budget to buy paper goods and plastic cutlery for an impromptu birthday party
the paper goods will cost 37.50
We need to find the difference of 65 dollars and 37.50 to determine the amount left to purchase cutlery
65-37.5
27.5
As by given, each cutlery set costs 0.75.
We need to divide 27.5 by 0.75 to find number of cutlery sets
27.5/0.75=36.6
Hence, Janet can buy 36 sets of cutlery.
