Answer:
It will take 20 minutes for both buckets to have the same amount of water
Step-by-step explanation:
Let "t" be the time in minutes when both the buckets will fill
The total volume in bucket A after t minutes
[tex]340 + 7t[/tex]
The total volume in bucket B after t minutes
[tex]640-8t[/tex]
[tex]340 +7t = 640-8t\\15 t = 300\\t = 20[/tex]
It will take 20 minutes for both buckets to have the same amount of water

Solve 2(x+3)=x-4
What is x?
Answer:
x=-10
Step-by-step explanation:
[tex]2(x+3)=x-4[/tex]
distributive property on left side:
[tex]2x+6=x-4[/tex]
subtract x from both sides
[tex]x+6=-4[/tex]
subtract 6 from both sides
[tex]x=-10[/tex]
Answer:
-10
Step-by-step explanation:
2(x+3)=x-4
Distribute (multiply everything in parenthesis):
2x+6=x-4
Subtract -x from both sides
X+6=-4
Subtract 6 from from both sides:
X=-10

Find the distance between these two points (5,9) and (-7,-7)
Answer:
20
Step-by-step explanation:
Use the distance formula:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}\\d = \sqrt{(-7 - 5)^2 + (-7 - 9)^2}\\d = \sqrt{(-12)^2 + (-16)^2}\\d = \sqrt{144 + 256}\\d = \sqrt{400} = 20[/tex]
The distance between the points (5,9) and (-7,-7) will be 20 units.
What is the distance between two points?The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
D² = (x - p)² + (y - q)²
The points are given below.
(5,9) and (-7,-7)
Then the distance between the points will be
D² = (5 + 7)² + (9 + 7)²
D² = 12² + 16²
D² = 144 + 256
D² = 400
D = 20 units

12 ^ x = 205 in logarithmic form
Answer:
x=2.142137
Step-by-step explanation:
Solve Exponent.
12x=205
log(12x)=log(205)(Take log of both sides)
x*(log(12))=log(205)
x=
log(205)
log(12)
x=2.142137

How to add/subtract like radical expressions?
[tex] \sf{in \: your \: own \: words \: please}[/tex]
9514 1404 393
Explanation:
"Like" radicals can be added and subtracted in the same way any like terms can be combined. It can be helpful to simplify the radical as much as possible so that it can be seen whether the radicals are "like" or not.
Examples:
√2 +√3 . . . . cannot be combined
√2 +√8 = √2 +2√2 = 3√2 . . . . the simplified radicals can be combined

Answer: the answer is x=4 so its option D
Step-by-step explanation:
i first set up a equation which looks like:
8x-12=20
then i have added 12 both sides so 20+12= 32 now im
left with: 8x=32
Now we divide so 32/8= 4
which why x=4

Find the percent change. 150 pounds to 135 pounds.
Answer:
-10%
Step-by-step explanation:
precent change = 135 - 150
(divide both sides by 150)
precent change = -0.1
(multiply both sides by 100 so change to precent)
precent change = -10%
Answer:
10%

A savings account increases from $300 to $309. What is the percent increase of the savings account?
Answer:
9 percent
Step-by-step explanation:
Answer:
3%
Step-by-step explanation:
1st Method: Increase Formula = (Last value-first value)/(first value)
Increase = (309-300)/300 = 9/300 = 3/100
= 0.03 or 3%
2nd Method: 309/300 = 103/100 = 1.03 (increase over 1 is 0.03 = 3%
A model of a skyscraper was made by an architect. the model was 15 inches high. if the architect used a scale of 2 inches representing 160 feet what would be the actual height of the building
Answer:
1200 feet
Step-by-step explanation:
A scale is a representative faction which can be used to either increase or decrease the size or dimensions of an object.
scale = [tex]\frac{model height}{actual height}[/tex]
[tex]\frac{2inches}{160 feet}[/tex] = [tex]\frac{15 inches}{actual height}[/tex]
actual height = [tex]\frac{15 *160}{2}[/tex]
= [tex]\frac{2400feet}{2}[/tex]
= 1200
actual height = 1200 feet
The actual height of the skyscraper is 1200 feet.
Find the missing measurements of the right triangle. Round your answers to the
nearest tenth if necessary.
You can use the calculator below!
Answer:
m∠B = 63°
AB = 26.4
AC = 23.6
Step-by-step explanation:
m∠B = 90 - 27 = 63°
Sin 27 = 12/AB
AB (sin 27) = 12
AB = 12/sin 27 = 26.4
Tan 27 = 12/AC
AC (tan 27) = 12
AC = 12/tan 27 = 23.6

i believe it would be 16.
Step-by-step explanation:
Answer:
Answer is x = 14.665 which rounded off is 14.67
All I did was Cos 39 = x / 55
0.26664293236 = x / 55
0.26664293236 × 55 = x
x = 14.665
x = 14.67
