Solve: 3^x+1 + 3^x= 108
Answer:
x = 3
Step-by-step explanation:
[tex] {3}^{(x + 1)} + {3}^{x} = 108 \\ \\ {3}^{x} .3 + {3}^{x} = 108 \\ \\ {3}^{x} (3 + 1) = 108 \\ \\ {3}^{x} (4 )= 108 \\ \\ {3}^{x} = \frac{108}{4} \\ \\ {3}^{x} = 27 \\ \\ {3}^{x} = {3}^{3} \\ \\ \implies x = 3[/tex]

Using the tangent ratio, the value of x, to the nearest tenth, is: 5.5.
How to Use the Tangent Ratio to Solve a Triangle?Given a right triangle with a missing length, x, we have the following:
∅ = 70°
Opposite side length = 15
Adjacent side length = x
The tangent ratio to be applied is:
Tan ∅ = opp/adj
Plug in the values
Tan 70 = 15/x
x(tan 70) = 15
x = 15/tan 70
x ≈ 5.5

Answer:
205.79 or 205.8
Step-by-step explanation:
sin (19) = 67/x *put sin (19) over 1 & cross multiply
x (sin (19)) = 67 *divide by sin (19)
x = 67/sin (19)
x = 205.79 = 205.8

An object is thrown upward out of a building window. The equation h=-16t²+40t+24 models the height in feet, h, of the object above the ground t seconds after it is thrown. How long does it take for the object to hit the ground?
9514 1404 393
Answer:
3 seconds
Step-by-step explanation:
We want to find t when h=0.
0 = 2t² -5t -3 . . . . . . . divide by -8
0 = (2t +1)(t -3) . . . . . . factor
The values of t that satisfy this equation are the values that make the factors zero: t = -1/2, t = 3. The positive value is the one of interest.
It takes 3 seconds for the object to hit the ground.

In a fishing contest, the length of the fish caught ranged from 11.5 inches to 23 inches with a mean length of 16.40 inches and standard deviation of 4.71 inches. Assume there was a normal distribution. What percent of the fish caught would have a length greater than 21.11 inches, one standard deviation above the mean?
Answer:
15 percent
Step-by-step explanation:
Based on the length of the fish and the standard deviation above the mean, the percentage of fish that will have a length of more than 21.11 inches is 15.9%.
What percentage of fish will be longer than 21.11 inches?Using the z table, we find that the z score probability for a length less than 21.11 inches when there is one standard deviation above the mean is 0.841.
The percentage of fish that are greater than 21.11 inches will therefore be:
= 1 - probability that fish is shorter than 21.11 inches
= 1 - 0.841
= 0.159
= 15.9%

Answer:
[tex] \displaystyle \angle3 = {90}^{ \circ} [/tex]
Step-by-step explanation:
we are given two angles
we are want to figure out the missing angle
remember,
Straight line theorem
so we acquire
[tex] \displaystyle \angle3 + \angle4 = {180}^{ \circ} [/tex]
substitute the value of the given angle:
[tex] \displaystyle \angle3 + {90}^{ \circ} = {180}^{ \circ} [/tex]
cancel 90° from both sides:
[tex] \displaystyle \angle3 = {90}^{ \circ} [/tex]
hence, the measure of the missing angle is 90°
Answer:
Solution given:
<4=90°
<3+<4=180°[sum of pair of line is supplementary]
<3=180°-90°
<3=90°is a required answer.

23=x-13
9+x=14
12=x+8
Answer:
23=x-13, x=36
9+x=14, x=5
12=x+8, x=4
Step-by-step explanation:
23=x-13. You want to isolate x so you have to add 13 to both sides. x=23+13, x=36
9+x=14. You want to isolate x so you have to subtract 9 from both sides. x=14-9, x=5.
12=x+8. You want to isolate x so you have to subtract 8 from both sides. x=4.

Median =
Mode =
Range =
Answer:
mean: 7
median = 8
mode = 9
range=7
Step-by-step explanation:
(3+4+7+9+9+10)/6 =7 so thast is mean
the middle number but there is none so between 7 and 9 is 8 so that is the median
mode is the number the appears the most in a data set so that is 9
range is literally the range so 3 to 10 is a range of 7
Answer:
mean=7
mode=9
median=8
range=7

Mahad and Eren made 17 ounces of pizza dough. They used 5/8 of the dough to make a pizza and used the rest to make calzones.
What is the difference between the amount of dough they used to make pizza and the amount of dough they used to make calzones?
A) 6 3/8 ounces
B) 4 2/8 ounces
C) 10 5/8 ounces
D) 17 5/8 ounces
Explain how you know.
9514 1404 393
Answer:
B) 4 2/8 ounces
Step-by-step explanation:
After 5/8 of the dough was used for pizza, the remaining amount is ...
1 -5/8 = 3/8
The difference between the amounts is then ...
(5/8×17 oz) - (3/8×17 oz) = (5/8 -3/8)×17 oz = 2/8×17 oz = 34/8 oz
= 4 2/8 oz
