look at the picture find the value of z
Answer:
Z=7.9
Step-by-step explanation:
20.4 + 20.4 = 40.8
56.6 - 40.8 = 15.8
15.8/2 = 7.9
Answer:
z=7.9 cm
Step-by-step explanation:
So, what we have to do is gather all the information we already have. The length of the rectangle is 20.4 cm, and the perimeter is 56.6. To find the perimeter, you always add all the sides up. So 20.4+20.4 is 40.8. since 4+4 is 8, and 20+20 is 40. Then, you subtract that from the perimeter to get what is 2z(both sides). 56.6-40.8 is 15.8. So we know 2z is 15.8. To find z, we divide 15.8 by 2 which is 7.9. You can do this with a calculator or write it down.
z=7.9 cm
A bin has 5 white balls and k black balls in it, where k is an unknown positive integer. A ball is drawn at random from the bin. If a white ball is drawn, the player wins 1 dollar, but if a black ball is drawn, the player loses 1 dollar. If the expected loss for playing the game is 50 cents, then what is k?
Answer:
Step-by-step explanation: The expected loss is 50 cents, we know that it is more likely to lose than win. It is therefore difficult to get-50, so the overall difference between the two possibilities is 2, 50/200=1/4, and the probability to win is 1/4, and the probability to lose is 3/4. Since (1/4)*3=3/4, the number of black balls is 3 times the number of white balls, so k=15.

A box plot display consist of a five-number summary. The five-number summary includes the following five values that is depicted in the box plot display:
1. Min value: the least value or smallest value indicated at the end of the whiskers to our left.
2. Max value: the largest value in the data set indicated at the end of the whisker to our right.
3. The median: this is a measure of center indicated by the vertical line that divides the rectangular box into 2.
4. The Upper quartile (Q3): this is indicated by at the end of the rectangular box at our far right.
5. The lower quartile (Q1): this is indicated at the beginning of the rectangular box from our left.
The interquartile range is the difference between the Q3 and the Q1, which can be used as a measure of spread of a data set.
Therefore, the most appropriate measures of center and spread for the data set above, are the median and the interquartile range respectively.
The correct choices are option C and D.
Rewrite the function in y.
2x – 4y = 8
Answer:
-4y=8-2x
Step-by-step explanation:
a guess
Answer:
y = 1/2 x -2
Step-by-step explanation:
2x – 4y = 8
Solve for y
Subtract 2x from each side
2x – 4y -2x= -2x+8
-4y = -2x+8
Divide each side by -4
-4y/-4 = -2x/-4 + 8/-4
y = 1/2 x -2
There are six poles on a side of a 1 km 200 m long straight road such that there is a pole at the starting and end points of the road. If the poles are equally spaced, then what is the distance between each consecutive pole?
Answer:
Distance is 200m between each pole
Step-by-step explanation:
First, convert the length of the road into meters
1km= 1000m
1000m +200m= 1200m
There are 6 poles on the side and they're equally spaced
Divide the length of the road by the number of poles to get the distance between the poles
Distance between poles= Length of road/ Number of poles
Distance between poles= 1200m/ 6 poles
Distance between poles= 200m
If f(x) = -8x + 8 and g(x) = (x–9,
what is (fºg)(18)?
Enter the correct answer.
DOHO
DONE
Clear all
OOO
o
HURRY !
Answer:
Step-by-step explanation:
(f ° g)(18) is another way of writing f(g(18)) which is telling you to evaluate function g at an x value of 18, then take that answer and plug it in for x in the function. Like this:
g(18) = 18 - 9 so
g(18) = 9. Now take that 9 and plug it into the f function in place of x:
f(9) = -8(9) + 8 and
f(9) = -72 + 8 so
f(9) = -64
3x - 17 = 46 . solve for x
Answer:
[tex]x = 21[/tex]
Step-by-step explanation:
We can simplify this equation down until we have x isolated.
[tex]3x - 17 = 46[/tex]
If we add 17 to both sides:
[tex]3x = 63[/tex]
Now we can divide both sides by 3:
[tex]x = 21[/tex]
So [tex]x = 21[/tex].

se tiene que embaldosar el patio interior de un edificio con baldosas cuadradas de 30 cm de lado. El patio es rectangular y sus medidas son 10 m por 12 m. ¿cuantas baldosas se necesitaran?
Answer:
40,000 baldosas
Step-by-step explanation:
Lo primero que debemos hacer aquí es calcular el área del patio rectangular.
El mejor enfoque para esto es convertir primero sus medidas a centímetros
Matemáticamente, 100 cm = 1 m, entonces 10 m se convierten en 1000 cm y 12 m se convierten en 1200 m.
El área de un rectángulo es L * B y, por lo tanto, tenemos 1200 * 1000 = 1,200,000 cm ^ 2
Ahora, para saber la cantidad de azulejos que tendrá el patio, necesitaremos dividir el área del patio por el área de los azulejos
Matemáticamente, eso sería 1,200,000 / 30 = 40,000 fichas
Two cars leave the park at the same time one travels north at a speed of 50 km an hour for two hours the second car travels west at a speed of 80 km an hour for two hours after the two hours how far apart are the two cars
Answer:
50 km/hr * 2hr = 100km
80 km/hr * 2hr = 160km
using pythagorean theorem: x = sqrt((a^2)+(b^2))
x = sqrt ((100^2) + (160^2)
x = 188.67 km

ASAP!! Please help me. I will not accept nonsense answers, but will mark as BRAINLIEST if you answer is correctly with solutions.
Answer:
see below
Step-by-step explanation:
The cube root is defined for all real numbers, but squaring it makes the first term of F(x) be non-negative. Hence the domain of F(x) is all real numbers, and its range is [-2, ∞).
Shifting the function 2 units left does not change the domain.
Shifting the function 4 units up moves the range to [2, ∞).

A container has 250 liters of water in it. Some water evaporated and then the container had only 175 liters in it. What percentage of water evaporated?
Answer:
Hey there!
A total of 250-175, or 75 liters of water evaporated.
75/250=0.3, or 30%
30% of water evaporated.
Hope this helps :)
Hey there! I'm happy to help!
First, let's find out how much water evaporated. We have 175 left of the 250 after evaporation, so we need to subtract 175 from 250 to see how much water evaporated.
250-175=75
75 liters evaporated. Now, we want to find this as a percent out of 250. 75 is what percent of 250? Well, when talking about percents, the word "is" means "equals". So, we can turn this into an equation! We will use x to represent our percent as a decimal.
75= x·250
We simply divide both sides by 250 to isolate the x, giving us x=0.3
0.3 is 30% as a percent, so this means that 30% of the water evaporated.
I hope that this helps! Have a wonderful day!

Jan wants to lay sod on this lot. How
much sod does he need?
In sq.ft.
Type in your response.
Answer:
148.5 sq. ft.
Step-by-step explanation:
Since Jan wants to lay sod on it, Sod required will be equal to area of the lot.
Lot is in trapezium shape
area of trapezium is given by = 1/2(sum of parallel sides) height
parallel sides has length 15 and 18 feet
sum of parallel sides = (15+18) = 33
height = 9 feet
thus area of lot = 1/2(33)9 = 148.5
Thus, Jan will need 148.5 sq. ft of sod.
