Rectangle ABCD was dilated to create rectangle A'B'C'D. Triangle A B C D is dilated to form triangle A prime B prime C prime D. Side B C is 3.8 units. Side A prime B prime is 15 units and side B prime C prime is 9.5 units. What is AB? 6 units 7.6 units 9.5 units 12 units
Answers
Answer:
[tex]AB = 6[/tex]
Step-by-step explanation:
Given
[tex]BC = 3.8[/tex]
[tex]A'B' = 15[/tex]
[tex]B'C' = 9.5[/tex]
Required
Determine the length of AB
Because A'B'C'D is a dilation of ABCD, then the following relationship must exist:
[tex]A'B' : AB = B'C' : BC[/tex]
Substitute values for A'B', B'C' and BC
[tex]15 : AB = 9.5 : 3.8[/tex]
Express the ratio as fractions:
[tex]\frac{AB}{15} = \frac{3.8}{9.5}[/tex]
Multiply through by 14
[tex]15 * \frac{AB}{15} = \frac{3.8}{9.5} * 15[/tex]
[tex]AB = \frac{3.8}{9.5} * 15[/tex]
[tex]AB = \frac{3.8* 15}{9.5}[/tex]
[tex]AB = \frac{57}{9.5}[/tex]
[tex]AB = 6[/tex]

Four bags of dry dog food plus 9.5 pounds of dry cat food weigh pounds in all. How many pounds does each bag of dog food weigh?
Answers
Answer:
Each bag of dog food weighs 2 pounds
Step-by-step explanation:
Here is the complete question:
Four bags of dry dog food plus 9.5 pounds of dry cat food weigh 17.5 pounds in all. How many pounds does each bag of dog food weigh?
Step-by-step explanation:
From the question,
Four bags of dry dog food plus 9.5 pounds of dry cat food weigh 17.5 pounds in all.
Let the weight of one bag of dry dog food be x.
Then we can write that
4x + 9.5 pounds = 17.5 pounds
To determine x, subtract 9.5 pounds from both sides
4x + 9.5 pounds - 9.5 pounds = 17.5 pounds - 9.5 pounds
4x + 0 = 8 pounds
4x = 8 pounds
Divide both sides by 4
4x/4 = 8 pounds/4
x = 2 pounds
∴ The weight of one bag of dry dog food is 2 pounds.
Hence, each bag of dog food weighs 2 pounds.

A 12-meter ladder leans against a building forming a 30° angle with the building.
Exactly how high is the ladder on the building in meters? Round to the nearest hundredth
(2 digits after the decimal).
Answers
Answer:
will show you two (2) ways to solve this problem.
A diagram is needed to see what is going on....
Without loss of generality (WLOG)
The wall is on the right. The ladder leans against the wall
with a POSITIVE slope, from SW to NE (quadrant 3 to quadrant 1).
The measure from the bottom of the ladder to the wall is 6.
Option 1:
The ladder, ground and wall form a right triangle.
The hypotenuse (ladder) is 14 feet.
The bottom of the ladder is 6 feet from the wall,
so the base of this right triangle is 6 feet.
The top of the ladder to the ground represents
the missing leg of the right triangle.
The pythagorean theorem applies, which says
6^2 + h^2 = 14^2 where h is the height
of the top of the ladder to the ground
36 + h^2 = 196
h^2 = 196 - 36
h^2 = 160
h = sqrt(160)
= sqrt(16 * 10)
= sqrt(16)* sqrt(10)
= 4*sqrt(10) <--- exact answer
= 4 * 3.16227766016838....
= 12.64911....
12.65 <--- rounded to 2 digits as directed
----------------------------------------------
Option #2: using trig
With respect to the angle formed by the bottom of the
ladder with the ground
cos T = 6/14 = 3/7
T = inverse-cosine(3/7) = 64.623006647 degrees
sin(64.623006647) = h/14
h = 14*sin(64.62300647) = 12.6491106 <--- same answer
hope this helps

write the equation for the parabola that has x-intercepts (2,0) and (3,0) and y intercept (0,-1.2)
Answers
Answer:
i think its y=-0.2x^2+x-1.2
Step-by-step explanation:
i could be wrong tho ngl
The equation of the parabola with x-intercepts (2,0) and (3,0) and y-intercept (0,-1.2) will be y = (-1/5)(x - 2)(x - 3).
What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.
The graph is easy to understand the behavior of the graph.
For example y = x² form a parabola now by looking at only the graph we can predict that it has only a positive value irrespective of the interval of x.
The equation of a parabola is written as,
y = a(x - b)(x - c) here b and c are two x-intercepts while (a,y) is the y-intercept.
As per the given,
x-intercept = (2,0) and (3,0)
y-intercept = (0,-1.2)
y = a(x - 2)(x - 3)
-1.2 = a(0 - 2(0 - 3)
a = -1/5
Thus,
y = (-1/5)(x - 2)(x - 3)
Hence "The equation of the parabola with x-intercepts (2,0) and (3,0) and y-intercept (0,-1.2) will be y = (-1/5)(x - 2)(x - 3)".

josefina pain rent for 5 months. She paid a total of $2045. how much did she pay per month?
Answers
Answer:
$409 per month
Step-by-step explanation:
If josefina paid $2045 over a time period of 5 months, then we have to divide how much she paid ($2045) by 5 to find out how much she paid for rent in 1 month.
We can use the equation: 2045 ÷ 5
When we solve that equation, we get 409 which means that josefina paid $409 per month for rent.

Step-by-step explanation:
Δ TSU and Δ TRV are similar , thus the ratios of corresponding sides are equal, that is
[tex]\frac{TS}{TR}[/tex] = [tex]\frac{TU}{TV}[/tex] , substitute values
[tex]\frac{x}{x+16}[/tex] = [tex]\frac{5}{15}[/tex] = [tex]\frac{1}{3}[/tex] ( cross- multiply )
3x = x + 16 ( subtract x from both sides )
2x = 16 ( divide both sides by 2 )
x = 8

At a club fundraiser a group of students washed 84 cars in one weekend. The next weekend, they washed 112 cars. What was the percent increase in the nunbers of cars washed?
Answers
Answer:
33.33%
Step-by-step explanation:
The computation of the percentage increase in the number of car washed is as follows;
= (Number of cars washed in next weekend - number of cars washed in one weekend) ÷ (number of cars washed in one weekend)
= (112 cars - 84 cars) ÷ (84 cars)
= 28 cars ÷ 84 cars
= 33.33%
Segment AB falls on line 6x + 3y = 12. Segment CD falls on line 4x + 2y = 8. What is true about segments AB and CD? They are parallel because they have the same slope of −2. They are parallel because they have the same slope of one half. They are lines that lie exactly on top of one another because they have the same slope and the same y-intercept. They are lines that lie exactly on top of one another because they have the same slope and a different y-intercept.
Answers
The lines 6x + 3y = 12 and 4x + 2y = 8 lie exactly on top of one another because they have same slope and same y intercept.
What are the coincident lines?The lines which coincide or lie on the top of each other are called coincident lines.
When the two lines coincide to each other?Two lines coincide to each other when they have same slope and same y intercept.
According to the given question.
We have two equation of lines.
[tex]6x + 3y = 12...(i)[/tex]
And, [tex]4x + 2y = 8...(ii)[/tex]
The equation (i) can be written as
[tex]2x + y = 4[/tex]
And equation (ii) can be written as
[tex]2x + y = 4[/tex]
Since, both the lines have same slope and same y intercept. Therefore, the given two lines coincide to each other.
Hence, the lines 6x + 3y = 12 and 4x + 2y = 8 lie exactly on top of one another because they have same slope and same y intercept.

Jen used 1/2 cup of cereal and 2/3 cup of nuts to make trail mix. Her mother asked if she used more cereal or more nuts in the mix. Which statement correctly compares the fractions?
Answers
1/2<2/3. 1/2= half of a whole and half of a whole is 1/2. 2/3 is over a half so it means that 2/3 is better then 1/2 since 1.5 is actually the half of 3. Jen should say that she used more nuts to make trail mix then using cup of cereal to make trail mix because 2/3 is greater then 1/2.
