The net of a cube is shown below. If the surface area of the net is 294 in^2 , then what is the length of each side of the cube?
Answer:
7 in
Step-by-step explanation:
294:6=49
[tex]\sqrt{49}=7 in[/tex]
The length of each side of the cube is 7 inches.
What is surface area of a cube?The surface area of the cube all six faces of the cube are made up of squares of the same dimensions then the total surface area of the cube will be the surface area of one face added six times to itself. The formula to find the surface area of a cube is 6a², where a is edge.
Given that, the surface area of a cube is 294 square inches.
Now, 6a²=294
a²=294/6
a²=49
a=7 inches
Therefore, the length of each side of the cube is 7 inches.

What is the y-intercept of y=2x-5 ?
Answer:
the y intercept is -5
Step-by-step explanation:
because the equation is y=MX+b
Answer:
The y-intercept is -5.
Step-by-step explanation:
[tex]y=2x-5[/tex]
The equation is in slope intercept form.
[tex]y = mx+b\\\\m - \text{Slope}\\\\b - \text{Y-intercept}[/tex]
Since ' -5 ' is in 'b' 's place, it is the y - intercept.

tan(x)/sec(x)=sin(x)
Answer:
(identity has been verified)
Step-by-step explanation:
Verify the following identity:
tan(x)/sec(x) = sin(x)
Hint: | Eliminate the denominator on the left hand side.
Multiply both sides by sec(x):
tan(x) = ^?sec(x) sin(x)
Hint: | Express both sides in terms of sine and cosine.
Write secant as 1/cosine and tangent as sine/cosine:
sin(x)/cos(x) = ^?1/cos(x) sin(x)
Hint: | Come to a conclusion.
The left hand side and right hand side are identical:
Answer: (identity has been verified)

-6 + 2/5c = 24
Answer:
c = 75
Step-by-step explanation:
Add 6 to both sides: 2/5c = 30
Divide both sides by 2/5 (or multiply by reciprocal of 5/2): c = 150/2
c = 75

Trigonometry help finding the value of x
Answer:
[tex]5\sqrt{3}[/tex] or 8.66
Step-by-step explanation:
use tan:
tan = [tex]\frac{opposite}{adjacent}[/tex]
⇒ tan 60 = [tex]\frac{x}{5}[/tex]
tan of 60 is 1.73
⇒ 1.732 = [tex]\frac{x}{5}[/tex]
multiply 5 on both sides
⇒ 1.732 x 5 = [tex]\frac{x}{5}[/tex] x 5
⇒ 8.66
Answer:
[tex]\boxed {\boxed {\sf D. \ 5 \sqrt 3 \ or \ 8.66}}[/tex]
Step-by-step explanation:
Remember the 3 main trigonometric ratios:
sinθ= opposite/hypotenuse cosθ= adjacent/hypotenuse tanθ= opposite/adjacentWe are given the 60 degree angle. 5 is adjacent to the angle and x is opposite. Therefore, we must tangent.
[tex]tan \theta= \frac {opposite}{adjacent}[/tex]
[tex]tan60=\frac {x}{5}[/tex]
Since we are solving for x, we must isolate that variable. It is being divided by 5 and the inverse of division is multiplication. Multiply both sides by 5.
[tex]5(tan60)=\frac {x}{5} *5[/tex]
[tex]5(tan60)=x\\5*$$1.73205080757= x\\8.66025403784=x[/tex]
If we round to the nearest hundredth, the 0 in the thousandth place tells us to leave the 6.
[tex]8.66 \approx x[/tex]
x is about 8.66 or 5√3, which is choice D.

11/6=n+7/9 what does n equal
Answer:
n = 19/18
Step-by-step explanation:
11/6 = n + 7/9
-n + 11/6 = 7/9
-n = 7/9 - 11/6
-n = -19/18
n = 19/18
Answer:
n = 19/18
Step-by-step explanation:
The equation 11/6=n+7/9 has fractions with two different denominators (6 and 9). The LCD is 18, which is the smallest number evenly divisible by 6 and 9. Thus, we can rewrite 11/6=n+7/9 as:
33/18 = (18/18)n + 14/18 (Now all three denominators are the same: 18)
Then 33 = 18n + 14, or
19 = 18n
Dividing both sides by 18, we get n = 19/18
Check: Is 11/6 = 19/18 + 7/9 true? YES
