Answer:
[tex]k = \frac{3}{10} [/tex]
Step By Step Explanations:
1) Multiply both sides by 2k.
[tex]3 = 5 \times 2k[/tex]
2) Simplify 5 × 2k to 10k.
[tex]3 = 10k[/tex]
3) Divide both sides by 10.
[tex] \frac{3}{10} = k[/tex]
4) Switch sides.
[tex]k = \frac{3}{10} [/tex]
Therefor, the answer is k = 3/10.

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(12)
x=2.142137
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

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

Step-by-step explanation:
The height of a right cone is 3 inches shorter than the radius. What is the height of the cone if the volume is 17 cubic inches?
a. 3.454 inches
b. 4.01 inches
c. 7.01 inches
d. 1.01 inches
Answer:
1.03 inches
Step-by-step explanation:
Volume of a come = 1/3πr²h
If the height of a right cone is 3 inches shorter than the radius, then;
h = r - 3
Substitute
V = 1/3πr²(r-3)
Given that V = 17in^3
17 = 1/3πr²(r-3)
17*3 = 3.14r²(r-3)
51/3.14 = r²(r-3)
16.242 = r²(r-3)
r² = 16.242
r = √16.242
r = 4.03
Since h = r - 3
h = 4.03 - 3
h = 1.03 inches
hence the height is 1.03 inches
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%
What number would represent 56 feet below sea level?
Answer:
-56
Step-by-step explanation:
That is because the 56 is below sea level, not above it, so it would be negative 56
Hope that helps!
-56ft
Since it is BELOW sea level it would be considered a negative number. If it were ABOVE sea level then it would be a positive number. Another way to think about this:
Above Sea Level = +
Below Sea Level = -
Hope this helps and have a nice day.
