Answer:
40
Step-by-step explanation:
A rain barrel is 65$ full
There are 26 gallons of water in the barrel
Therefore the numberr of gallons of water the barrel will hold can be calculated as follows
= 26×100/65
= 2600/65
= 40
Hence the barrel will hold 40 gallons of water
(Pythagoras Theorem) Hi, I need help with this question. How am I suppose to find the length of the one-edge path A-C-G?
Answer:
AB = 60
BC = 80
Pythag: 60^2 + 80^2 = c^2
3600 + 6400 = 10000
c=100
A-C = 100
C-G = 120
100 + 120 = 220
A - C - G = 220 cm
A placement test is administered to collegiate freshmen. The test is known to be approximately normal with a mean of 65 and a standard deviation of 5. Sheila scored a 59 on this test. Does this score place Sheila in the bottom 10% of test takers?
Answer: D. She is above 11.5% of test takers
Step-by-step explanation:
So logically we can eliminate like 3 answers and let me explain why
So first we can eliminate both A and B because the question asks "Does this score place Sheila in the bottom 10% of test takers?" If the answer were yes she wouldn't be "above 8.5%" or "above 11.5%" because she would be below.
So that would leave both C and D right. Lets look at C first. It says "No, she is above 8.5% of test takers" But if she is above 8.5% she could hypothetically be in the 9% or the 9.5% of test takers. Since this answer doesn't gurantee she would be above 10% we can't choose it. Now D it says "No, she is above 11.5% of test takers" This is correct because She is not in the bottom 10% because according to the empirical rule she is I would say around or just under 16% of test takers. Also the 11.5% part gurantees that anything above the number 11.5 is greater than 10%. Unlike in C which only says the number is greater than 8.5 which means the number could be 8.6 which is NOT greater than 10.

Find the value of the expression below for x=3
x^2+5
Answer: 14
Step-by-step explanation: 3 to the second is 3 twice EX. 3x3=9, 9+5=14
Answer: x= −5 /2 + 1 /2 √37 or x= −5 /2 + −1 /2 √37
Step-by-step explanation:
Step 1: Subtract 3 from both sides.
x2+5x−3=3−3
x2+5x−3=0
For this equation: a=1, b=5, c=-3
1x2+5x+−3=0
Step 2: Use quadratic formula with a=1, b=5, c=-3.
x= −b±√b2−4ac /2a
x=
−(5)±√(5)2−4(1)(−3) /2(1)
x= −5±√37 /2
x= −5 /2 + 1 /2 √37 or x= −5 /2 + −1 /2 √37

LAST QUESTION PLS HELP. (It's not solve for x)
Answer:
40
Step-by-step explanation:
So, if the angle shown, one of them is 70. the other is 110, because line is 180 degress, 180-70 = 110. C is 110. But, we need to find B. 13x + 6 must also be 70 degrees. 70-6 = 64. 64/13 = about 5. A is 100. The inner angles are 70+70+N. Angles in triangle are 180, so N is 180-70-70, which is 180-140. The B is 40 degrees.
Answer:
m∠ABC = 26°
Step-by-step explanation:
13x+6 + 8+3x + 70 = 180
16x + 84 = 180
16x = 96
x = 6
m∠B = 8+3(6) = 26°

A farmer is painting his silo. A typical can of paint covers 400 squared meters. How many cans of paint will the farmer need to buy in order to paint the entire exterior of the silo?
Answer:
about 13 cans of paint
Step-by-step explanation:
To find how many cans the farmer needs to buy, you need to know the surface area of both the cone and cylinder.
The way to find the SA of the cone would be area = 3.14 x r^2 + 3.14 x r x sqrt(r^2 + h^2).
SA= 1976.0617791 m^2.
The way to find SA of the cylinder under the cone would be 3.14 x d x (d / 2 + h).
A = 3097.6103564 m^2
Then you have to add 1976.0617791+3097.6103564 which gives you 5,073.8. (5,073 being total surface area of the silo)
Next divide that by 400.
5,073.8/400 = 12.7
He would need to buy about 13 cans of paint to be able to paint the entire silo.

Your input: factor x2+4x+3.
To factor the quadratic function x2+4x+3, we should solve the corresponding quadratic equation x2+4x+3=0.
Indeed, if x1 and x2 are the roots of the quadratic equation ax2+bx+c=0, then ax2+bx+c=a(x−x1)(x−x2).
Solve the quadratic equation x2+4x+3=0.
The roots are x1=−1, x2=−3 (use the quadratic equation calculator to see the steps).
Therefore, x2+4x+3=1(x+1)(x+3).
(x2+4x+3)=1(x+1)(x+3)

The area of a rhombus is 36 sq. cm. If its perimeter is 16cm, find its altitude.
Answer:
Perimeter of rhombus =4×l
16=4l
l=16/4=4
its length =4cm
area of rhombus=36cm²
base× height (here base=length)=36cm²
4h=36
h=36/4=9

Please help! would really appreciate it.
Answer:
Step-by-step explanation:
Use Pythagorean theorem,
Base² + altitude² = hypotenuse²
15² + altitude² = 17²
225 + altitude² = 289
altitude² = 289 - 225
altitude² = 64
altitude² = 8²
altitude = √8²
altitude = 8
P = 8 + 15 + 17 = 40 units
[tex]A= \frac{1}{2}*base * height\\\\ = \frac{1}{2}* 15 * 8\\\\= 15 * 4\\\\= 60 sq. units[/tex]

A paper company needs to ship paper to a large printing business. The paper will be
shipped in small boxes and large boxes. The volume of each small box is 6 cubic feet
and the volume of each large box is 22 cubic feet. A total of 22 boxes of paper were
shipped with a combined volume of 324 cubic feet. Write a system of equations that
could be used to determine the number of small boxes shipped and the number of
large boxes shipped. Define the variables that you use to write the system.
Answer:
10 small boxes and 12 large boxes
Step-by-step explanation:
Let x = number of large boxes
Let y = number of small boxes
We are told that;
volume of each small box = 6 cubic feet
volume of each large box = 22 cubic feet.
Total volume = 324 ft³
Thus;
6x + 22y = 324 - - - (eq 1)
We are told that 22 boxes of paper were shipped.
Thus; x + y = 22 - - - (eq 2)
Making x the subject in eq 2 gives;
x = 22 - y
Put 22 - y for x in eq 1;
6(22 - y) + 22y = 324
132 - 6y + 22y = 324
16y = 324 - 132
16y = 192
y = 192/16
y = 12
So, x = 22 - 12 = 10
