Answer:
195 plants (verified) ✅Step-by-step explanation:
We will use a proportion to solve this.
x/y = x/y
let x = the number of families in each case
let y = the number of plants in each case
Since we don't know the second y, we will leave that as y and solve for it.
50/150 = 65/y
Cross-multiply
50y = 9750
Divide
195 = y
Now, we can check this by substituting the value of y back into the equation and seeing if both sides equal.
50 (195) = 9750
9750 = 9750 ✅

A right rectangular pyramid is sliced vertically (down) at the red line by a plane not passing through the vertex of the pyramid. What is the shape of the cross-section.
A Trapezoid
B Triangle
C Rectangle
D Cylinder
Answer:
I feel like it might or might not be rectangle because it didn't pass through the vertex so it's almost like it's cutting off the top part of the pyramid.
Answer: Trapezoid
Step-by-step explanation:
I just did the test and got 100

The lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min. If one such class is randomly selected, find the probability that the class length is between 50.8 and 51 min.
Answer: the probability that the class length is between 50.8 and 51 min is 0.1 ≈ 10%
Step-by-step explanation:
Given data;
lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min
hence, height = 1 / ( 52.0 - 50.0) = 1 / 2
now the probability that the class length is between 50.8 and 51 min = ?
P( 50.8 < X < 51 ) = base × height
= ( 51 - 50.8) × 1/2
= 0.2 × 0.5
= 0.1 ≈ 10%
therefore the probability that the class length is between 50.8 and 51 min is 0.1 ≈ 10%
Assume the random variable x is normally distributed with mean u = 82 and standard deviation o =5. Find the indicated probability
-4 x f (8) + 3 x g(-7) HELP ASAP
Answer:
-32
Step-by-step explanation:
-4 + f(8) + 3 x g(-7) = ?
To find f(8), look at each of the f(x) function and find x = 8. The y value is the answer you will plug in for f(8). The same goes for g(-7), but you will be looking at the g(x) function at x = -7.
f(8) = -4
g(-7) = -8
Make sure you solve in the correct order using PEMDAS.
-4 + (-4) + 3 x (-8) = -32
URGENT if triangle FGH is congruent to triangle KJH, find FH
Answer:
FH =KH if triangle FJH and KJH is congruent
Step-by-step explanation:
If two triangles FJH and KJH as shown n figure is congruent if,
FJ = KJ,
FH =KH and
JH =JH common
Triangle is congruent by SSS theorem
Therefore FH =KH
Answer:
FH=39
Step-by-step explanation:
FGH~KJH
GH=x+8
FH=4x-25
JH=32
KH=52
(these are the measurements I have)
x+8 / 32 = 4x-25 / 52
(cross multiply)
52(x+8) = 32(4x-25)
52x+416 = 128x-800
(subtract the 52x from the 128x)
416 = 76x-800
(add the 800 to the 416)
1216 = 76x
(divide the 76 over the 1216)
x = 16
(now plug x into FH)
FH = 4x-25
FH = 4(16)-25
FH = 39
(hope this helped)
In a batch of lightbulbs, 30% are tinted, if 45 lightbulbs are tinted, how many lightbulbs are in the batch?
Step-by-step explanation:
30% of lightbulbs = 45 lightbulbs
100% of lightbulbs
= 45 * (100/30) = 150 lightbulbs.
Hence there are 150 lightbulbs in the batch.

Martin's car had 86,456 miles on it. Of that distance, Martin's wife drove 24,901 miles,
and his son drove 7,997 miles. Martin drove the rest. How many miles did Martin drive?
Show work.
Answer:
Martin drove 53,558 miles.
Step-by-step explanation:
If you add up the amount of miles his son and wife drove, you get 32,898. To get the answer, you would subtract that from the total number of miles to get 53,558.

STOP RIGHT THERE. Please help me.
Answer:
the answer is B
Step-by-step explanation:
Well we can get rid of A and D because we're not adding money, we're subtracting (thats what a sale is)
So we're left with B and C.
To find what 17% of 3 is, we multiply 3 x 0.17, which totals to 0.51. It can't be C because you find 51% of 3 which is not what we're looking for, so it is B.

Answer:
(b) g(x) = -f(x+3)
Step-by-step explanation:
The dashed-line graph is a reflection over the x-axis and a left-shift by 3 of the solid-line graph. To reflect the function over the x-axis, negate it.
f(x) ⇒ -f(x) . . . . reflected over the x-axis
To translate a function to the right horizontally by "h" units, replace x in the function with (x-h). Here, we want a left shift, so h=-3. That is, x is replaced by (x+3).
Both transformations together give you ...
g(x) = -f(x+3)

Answer:
B. 112°
Step-by-step explanation:
4x -4 = (3x+4) + (2x-44)
4x -4 = 5x - 40
5x - 4x = -4 + 40
x = 36
∠BCA = 3 * 36 + 4 = 112

What is mzA? Enter your answer as only a number
Answer:
A = 25
B = 65
Step-by-step explanation:
Remark
I hope you mean what is the size of <A? If not leave a note. If I am correct than A and C are complementary (equal 90o) since B is a right angle.
Solution
2x + 1 + 5x + 5= 90 Combine like terms
7x + 6 = 90 Subtract 6 from both sides
7x = 90-6
7x = 84 Divide by 7
x = 84/7
x = 12
==========================
Now that is not quite the answer.
A = 2x + 1
A = 2*12 + 1
A = 25
B = 5x + 5
B = 5*12 + 5
B = 60 + 5
B = 65
