Juana is measuring two pyramids whose bases are isosceles right triangles.
Given the height hhh and the volume VVV of the first pyramid, Juana uses the formula
a=\sqrt{\dfrac{6V}{h}}a=
h
6V
a, equals, square root of, start fraction, 6, V, divided by, h, end fraction, end square root
to compute its base's side length aaa to be 111 meter.

Find the 8th term 50,20,8
Answer:
0
Step-by-step explanation:
Answer:
0.08192
Step-by-step explanation:
Given 50, 20, 8, ...
The sequence is geometric in nature
The nth term of the geometric sequence is exoressed as;
Tn = ar^{n-1}
a is the first term = 50
r is the common ratio = 20/50 = 8/20 = 2/5
n is the number of term = 8 (since we need the 8th term)
Substitute
T8 = 50(2/5)^{8-1}
T8 = 50(2/5)^7
T8 = 50(128/78,125)
T8 = 0.08192
Hence the 8th term is 0.08192.

solve the equation using the quadratic formula
2n^2+3n=-54
a) {4,-9}
b) {6,-2}
c) {9,-3}
d) {-4 1/2, 6}
Answer:
Step-by-step explanation:
Rewrite this quadratic equation in standard form: 2n^2 + 3n + 54 = 0. Identify the coefficients of the n terms: they are 2, 3, 54.
Find the discriminant b^2 - 4ac: It is 3^2 - 4(2)(54), or -423. The negative sign tells us that this quadratic has two unequal, complex roots, which are:
-(3) ± i√423 -3 ± i√423
n = ------------------- = ------------------

Zeros can be observed graphically or solved for algebraically. A linear function can have none, one, or infinitely many zeros. If the function is a horizontal line ( slope = [latex]0[/latex]), it will have no zeros unless its equation is [latex]y=0[/latex], in which case it will have infinitely many.

The total number of cars produced by TESLA each year is y = 200000(1.25)x , where x represents the number of years after 2020. how many cars will be produced in year 2025 (five years later)?
Answer:
y=1250000
Step-by-step explanation:
Multiply 200000 by 1.25.
y = 250000 ⋅5
Multiply 250000 by 5.
y=1250000

that's all that you have to do you replace the x with 4 and do a normal equation
Answer: y=13
Y=(4)^2-3
y=16-3
y=13
If 50 grams of sweats cost $2.10,find the cost of 380 of sweats,giving your answer correct to the nearest 5 cent
Answer:
$15.95
Step-by-step explanation:
cost of 1 gram of sweet = $2.10 / 50 = 0.042
Cost of 380 g = 380 x 0.042 = $15.96
to the nearest 5 cent = 15.95
Jess says that two of the three points below are on a line through the origin.
(3.8), (6, 21), and (9, 24)
Part A
Which two points could lie on the same line through the origin? Explain why. Explain why
the third point could not.
* I will give brainliest*
Answer:
(3, 8) and (9, 24) lie on the same line through the origin.
because (9, 24) is the result of dilatation of (3, 8) with scale factor 3.
(6, 21) is not the result, because 21 ≠ 2×8, even 6 = 2×3

Solve for x.
2x + 24
3x - 26
x = [?]
Answer:
set them equal to eachother, i gotta look at my notes tho
Step-by-step explanation:
I think it's like this
3x-26=2x+24
We simpilfy the equation to the form which is simple to understand.
3x-26=2x+24
We move allterms containing X to the left and all others terms to the right
+3x-2x=+24+26
We simplfiy left and right sideof the eqution.
+1x=+50
We divide both sides of the equation by 1 to get x.
x=50

Casey polled 50 seventh grade students. He asked who they planned to vote for as class president. Thirty students said they would vote for Lynne. Twenty said they would vote for Marcus.
Use this probability to predict how many seventh graders in their class of 450 students will vote for Lynne
Answer:
270 students
Step-by-step explanation:
First, you need to do a ratio.
30 x
------- = --------
50 450
In order to solve this, you need to multiply 450 times 30 and that equals 13500. 13500 divided by 50 is 270. That means that about 270 students will vote for Lynn.
What is the distance between two points(0,0)(-3,5)
Step-by-step explanation:
Think of it like a right triangle. Do you have a graph handy?
Ok, graph both of the points. Now connect the points. That's our hypotenuse and the side length we want to find.
Now, bring down a line from (-3,5) to the x axis. Do you see a right triangle?
All we have to do is find the hypotenuse of this right triangle we just drew. We already have the leg lengths which are 3 and 5. Using this, do the pythagorean theorem.
9+25=34
√34 is our hypotenuse & distance between the points

Gorilla A weighed 559 pounds, gorilla B weighed 827 pounds and gorilla C weighed 130 pounds. What is the combined weight of all three gorillas?
Answer:
1,516 pounds
Step-by-step explanation:
Gorilla A weighed = 559 pounds Gorilla B weighed = 827 pounds Gorilla C weighed = 130 pounds
Total weight of the gorillas = gorilla A + gorilla B + gorilla C
= 559 pounds + 827 pounds + 130 pounds
= 1,516 pounds
Total weight of the gorillas = 1,516 pounds
