The trapezoids below are similar. Find z.
Answers
Answer:
[tex]z = 24.5[/tex]
solving similarities:
[tex]\frac{upper-length}{bottom- length}=\frac{upper-length}{bottom- length}[/tex]steps:
[tex]\frac{2}{14} =\frac{7/2}{z}[/tex]
[tex]2z = \frac{14*7}{2}[/tex]
[tex]2z = 49[/tex]
[tex]z = 24.5[/tex]
Answer:
[tex]z = \dfrac{49}{2}[/tex]
Step-by-step explanation:
If the trapezoids are similar, then the ratio of side lengths will be equal.
[tex]\implies 14 : 2 = z : \dfrac72[/tex]
[tex]\implies \dfrac{14}{2}=\dfrac{z}{\frac72}[/tex]
[tex]\implies z=\dfrac{14}{2} \times \dfrac72[/tex]

A commercial jet and a private airplane fly from Denver to Phoenix. It takes the commercial jet 1.6 hours for the flight, and it takes the private airplane 2.4 hours.
The speed of the commercial jet is 180 miles per hour faster than the speed of the private airplane. Find the speed, in miles per hour, of both airplanes.
commercial jet
X mph
private airplane
X mph
Answers
Answer:
commercial: 540 mphprivate: 360 mphStep-by-step explanation:
Time is inversely proportional to speed for the same distance covered. The ratio of commercial to private speeds is ...
2.4 : 1.6 = 3 : 2
If p is the speed of the private plane, then 3/2p is the speed of the commercial plane and the difference of speeds is ...
3/2p -p = 180
1/2p = 180 . . . collect terms
p = 360 . . . . . . speed of the private plane
3/2p = 540 . . . . speed of the commercial plane
The commercial jet flies 540 mph; the private plane flies 360 mph.

Answers
Answer:
je
Step-by-step explanation:
suis suis pasforet en anglais
We're dealing with percentage. hence, our universal set: U=100%.
Let:A = set of those that read magazine A
B = set of those that read magazine B
C = set of those that read magazine C
(i) we are looking for n{(A n B) u (B n C)}
so, n{(A n B) u (B n C)} = n(A n B) + n(B n C) -n(A n B n C)
n{(A n B) u (B n C)} = 20% + 30% - 10%
: n{(A n B) u (B n C)} = 40%
(ii) We're looking for {A' n B' n C'}
{A' n B' n C'} = n(U) - n(A u B u C)
{A' n B' n C'} = 100% - n(A u B u C)
n(A u B u C) = n(A) + n(B) + n(C) - n{(A n B) - n(A n C) -n(B n C) + n(A n B n C)
n(A u B u C) = 60% + 50% + 50% -30% - 30% - 20% + 10%
n(A u B u C) = 90%
however, {A' n B' n C'} = 100% - n(A u B u C)
: {A' n B' n C'} = 100% - 90%
{A' n B' n C'} = 10%

Answers
Answer:
2/3 gallon
Step-by-step explanation:
If y is the amount Tommy should use, and he want to keep the same proportion, then the proportion is ...
y/(2 gal) = (1/2 gal)/(3/2 gal) = yellow/blue
y = (2 gal)(1/3) = 2/3 gal
Tommy should use 2/3 gallon of yellow paint.

y + 3 = -y + 9
O y = 1
O y = 3
O y = 6
O y = 9
Answers
Answer:
y = 3
Step-by-step explanation:
Subtract 3 from both sides of the equation
y + 3-3 = -y + 9-3
Simplify
y = -y + 6
Add y to both sides of the equation
y+y=-y+6+y
Simplify
2y = 6
Divide both sides of the equation by the same term
2y/2 = 6/2
Simplify
y = 3
[RevyBreeze]
The solution of the Equation is y= 3.
We have, the equation is
y + 3 = -y + 9
y + y = 9 - 3
2y = 6
Now, divide both side we get
2y = 6
2y/ 2 = 6/ 2
y = 3
Thus, the solution of y is 3.

Hi there I don't usually ask questions but I'm having a bit of trouble solving for X on this equation. 1+(3x-3)=1 You don't necessarily have to give me the answer, a break down would be just fine :)
Answers
Answer:
[tex]x=1[/tex]
Step-by-step explanation:
[tex]1+(3x-3)=1[/tex]
First, you have to take the one that is outside of the Parenthesis and take it to the other side. That would mean it would be this:
[tex]3x-3=1-1[/tex]
1 - 1 is 0
[tex]3x-3=0\\[/tex]
Move the -3 to the other side, which makes it positive;
[tex]3x=3[/tex]
Divide both sides by 3
[tex]x=1[/tex]
If you want to check it, you can replace 1 in the original equation:
[tex]1+(3X1-3)=1[/tex]
[tex]1+(0)=1[/tex]
[tex]1=1[/tex]
So x=1

Which of the following describes exponential decay?
A.) The amount at a given time can be calculated by subtracting an amount from the previous amount.
B.) The amount at a given time can be calculated by adding an amount to the previous amount.
C.) The amount at a given time can be calculated by multiplying the previous amount by a value less than 1.
D.) The amount at a given time can be calculated by multiplying the previous amount by a value greater than 1.
Answers
Answer:
C. The amount at a given time can be calculated by multiplying the previous amount by a value less than 1.
Step-by-step explanation:
Exponential decay is when an exponential function decreases per x-value. These functions go by a multiplier and are therefore, not linear, so you cannot add or subtract. Because the function is decaying, it is multiplying by an amount less than 1, since the multiplier is 1 - r, where r is the percent.
