Divide 4.5 by 0.75(cups of flour) which gives you 6. Multiply 6 by 1/2.
6. Trapezoid DEFG with vertices D(-5, 15), E(10, 10), F(10,5), and G(-5,0):
k = 1/5
Answer:
D (-1,3)
E (2,2)
F (2,1)
G (-1,0)
Step-by-step explanation:
Multiply each point by 1/5.
Or think of it as dividing each point by 5
D (-5,15) divide -5 by 5 get -1, divide 15 by 5 get 3
so, (-1,3)
The coordinate of the new trapezoid will be D'(-1, 3), E'(2, 2), F'(2, 1), and G'(-1, 0).
What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.
Trapezoid DEFG with vertices D(-5, 15), E(10, 10), F(10,5), and G(-5,0).
The scale factor will be 1/5. Then the coordinate of the new trapezoid will be given as,
D' = (-5/5, 15/5) = (-1, 3)
E' = (10/5, 10/5) = (2, 2)
F' = (10/5, 5/5) = (2, 1)
G' = (-5/5, 0/5) = (-1, 0)
The direction of the new trapezoid will be D'(- 1, 3), E'(2, 2), F'(2, 1), and G'(- 1, 0).

Step-by-step explanation:
A sold an article to B at a gain of 10% ,B sold it to C at a gain of 20% .If C paid Rs.2,640 for it,what did it cost A?
Help me with this question please
Answer:
$2,000
Step-by-step explanation:
Since B sold the article to C at a gain of 20%, 2,640 must be 120% or 1.2 times the price that B paid.
To find the price that B paid, we just need to divide 2,640 by 1.2, as the original price multiplied by 1.2 = a 20% increase.
2,640/1.2= 2,200
The price B paid for it must have been 2,200.
Now we know that 2,200 was the price sold by A to gain 10%, therefore it is 110% or 1.1 times the original price A paid for it. Therefore, once again to find the original price, we just need to divide it by 1.1:
2,200/1.1 = 2,000
The original price it cost A was $2,000.

1.A rectangular prism has a volume of 1080 cubic cm. Its dimensions are 5 cm, (x + 12) cm, and (x + 6) cm. What is the value of x?
Answer:
x = 6 cm
Step-by-step explanation:
Volume of a rectangular prism = length × width × height
Length = 5 cm
Width = (x + 12) cm
Height = (x + 6) cm
Volume of a rectangular prism = 1,080 cubic centimeter
Volume of a rectangular prism = length × width × height
1080 = 5 * (x+12) * (x+6)
1080 = 5 (x^2 + 6x + 12x + 72
1080 = 5 (x^2 + 18x + 72)
1080 = 5x^2 + 90x + 360
Divide through by 5
216 = x^2 + 18x + 72
Subtract 216 from both sides
x^2 + 18x + 72 - 216= 0
x^2 + 18x - 144 = 0
Using factorization method to solve the quadratic equation
x^2 + 24x - 6x - 144 = 0
x( x+ 24) - 6 ( x + 24) = 0
(x + 24) (x - 6) = 0
x + 24 = 0
x = -24
x - 6 = 0
x = 6
x = -24 or 6
x can not be a negative value , so, x = 6 cm

Bill's school is selling tickets to a spring musical. On the first day of ticket sales the school sold 5 adult tickets and 14 student tickets for a total of $198. The school took in $156 on the second day by selling 10 adult tickets and 8 student tickets. Find the price of an adult ticket and the price of a student ticket.
Answer: The price of an adult ticket = $6
The price of a student ticket = $12
Step-by-step explanation:
Let the price of an adult ticket be a
Let the price of a student ticket be b.
From the question,
5a + 14b = 198 ...... equation i
10a + 8b = 156....... equation ii
Multiply equation i by 10
Multiply equation ii by 5
50a + 140b = 1980 ...... equation iii
50a + 40b = 780 ....... equation iv
Subtract iv from iii
100b = 1200
b = 1200/100
b = 12
Put the value of b into equation ii
10a + 8b = 156
10a + 8(12) = 156
10a + 96 = 156
10a = 156-96
10a = 60
a = 6
The price of an adult ticket = $6
The price of a student ticket = $12

What is 25637 to 1 significant figure
Answer:
30000
Step-by-step explanation:
Currently there are 5 significant figures. Since there is a 5 after the 2, it would round it up to a 3. Zeros aren't considered significant figures unless there is a period. Therefore, 30000 is the answer. 3 is the 1 significant figure with four insignificant zeros.
Answer:
30000
Step-by-step explanation:
Remember non-zero numbers are significant.
Zero between non zero numbers are significant.
So 25637 to 1 significant figure is rounding it off to the nearest ten thousand in a simple way.
So 25637 to 1 significant figure simply becomes 30000.

Wilma works at a bird sanctuary and stores bird seed in plastic containers. She has 5 small containers that holds 8 pounds of bird seed each and 6 large containers that hold 12 pounds of bird seed each. Each container was full until she used 4 pounds of bird seed. She wants to put some of the remaining bordered into 26 bird feeders that can hold 2 pounds each. How much birdseed does she have left over? Show the expression you used to find your answer.
Answer: 56lb
Step-by-step explanation:
Wilma has:
5 small containers that hold 8 lb each: Here we have a total of 5*8lb = 40 lb
6 large containers that hold 12 lb each: Here we have a total of 6*12lb = 72 lb
There is a total of 40lb + 72lb = 112 lb.
Now we know that she uses 4 lb, so now she has:
112lb - 4lb = 108lb.
Now she wants to fill 26 bird feeders, that can hold 2 lb each.
So she needs 26*2lb = 52lb
The amount of bird seeds that she has left is:
108lb - 52lb = 56lb

subtract 15 from both sides:
x=-5
not 15 ;)
13+x=38
subtract 13 from both sides:
x=38-13
x=25
not 15 ;)
let's try the last option (it has to work)

Find the equation of a line that passes through the points (4, 3) and (8,1)
Answer: y= -1/2x + 5
Step-by-step explanation:
We will write the equation in slope-intercept form meaning that we will need to find the slope and the y-intercept.
The slope-intercept for is y=mx +b where m is the slope and b is the y-intercept.
Find the slope by find the difference in the y coordinates and divide it by the difference in the x-coordinates.
The y-coordinates are 3 and 1
The x coordinates are 4 and 8.
3-1 = 2
4-8 = -4
2/-4= -1/2
The slope is -1/2
We will now use one of the points and the slope to find the y-intercept by plotting their values into the formula .
3= -1/2(4) + b
3= -2 + b
+2 +2
b= 5
The equation will be y= -1/2x + 5

Hannah mixed 6.83 lb of pretzels with 3.57 lb of popcorn. After filling up 6 bags that were the same size with the mixture, she had 0.35 lb left. What was the weight of each bag cant figur it out 5th grade math
Answer:
1.675 lb
Step-by-step explanation:
Given that Hannah mixed 6.83 lb of pretzels with 3.57 lb of popcorn.
So, after mixing, the total amount of mixture is
6.83 lb + 3.57 lb = 10.40 lb.
After filling up 6 bags that were the same size with the mixture, she had 0.35 lb left, so 0.35 lb of the mixture is not in the bag.
So,he total amount of mixture in 6 bags = 10.40 lb - 0.35 lb=10.05 lb, which is the weight of 6 bags.
The weight of one bag =\frac {10.05}{6} lb
=1.675 lb
As all the bags are of the same size, so the weight of all the bags are same,
Hence, the weight of each bag is 1.675 lb.
