What is the solution of 10(w + 3)= 70?
Answer:
The solution is w=4
simply
-30
divide by 10
Answer:
W=4
Step-by-step explanation:
1 0 ( + 3 ) = 7 0
1 0 + 3 0 = 7 0
Subtract 30 from both sides of the equation
simplify
10w=40
Divide both sides of the equation by the same term
10/40
W=4

The factorization of a trinomial is modeled with algebra tiles. An algebra tile configuration. 3 tiles are in the Factor 1 spot: 1 is labeled + x, 2 are labeled negative. 4 tiles are in the Factor 2 spot: 1 is labeled + x and 4 are labeled +. 12 tiles are in the Product spot: 1 is labeled + x squared, 2 are labeled negative x, the 3 tiles below + x squared are labeled + x, and the 6 tiles below the negative x tiles are labeled negative. Which trinomial is factored?
x^2 + 3x – 6
x^2 + 5x – 6
x^2 + 3x – 2
x^2 + x – 6

Answer:
D.) $4 per min.
Step-by-step explanation:
in the first increase we go up 5 minutes and up $20
this trend stays equal just with 10 minute and $40 increases
this means that there is $20 for every 5 minutes so to find the unit rate we divide $20 by 5 which gives us 4

Perform the indicated operation and state the domain. Let f(x) = 3x^1/3 and g(x) = 2x^1/2 Express as (f+g)(x)
Answer:
[tex](f + g)(x) = 3x^{\frac{1}{3}}+2x^{\frac{1}{2}}[/tex]
[tex]x \ge 0[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 3x^{\frac{1}{3}}[/tex]
[tex]g(x) = 2x^{\frac{1}{2}}[/tex]
Solving (a): (f + g)(x)
In functions:
[tex](f + g)(x) = f(x) + g(x)[/tex]
So, we have:
[tex](f + g)(x) = 3x^{\frac{1}{3}}+2x^{\frac{1}{2}}[/tex]
Solving (b): The domain of f(x)
For (f + g)(x) to be defines, the value of x must be greater than or equal to 0.
Hence, the domain is:
[tex]x \ge 0[/tex]
Someone help and plz make sure the answer is correct plz :)
Answer:
slope = 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (16, 17) and (x₂, y₂ ) = (15, 16)
m = [tex]\frac{16-17}{15-16}[/tex] = [tex]\frac{-1}{-1}[/tex] = 1

Solve the problem in the photo.
Answer:
A, B, C, D, and F
Step-by-step explanation:
Replace x with the number options (remember to multiply the options by a negative one since x is negative).
3*-1=-3 -3 is greater than or equal to -4
-3*-1=3 3 is greater than or equal to -4
4*-1=-4 -4 is greater than or equal to -4
-4*-1=4 4 is greater than or equal to -4
4.001*-1=-4.001 -4.001 is not greater than or equal to -4, so this does not work
-4.001*-1=4.001 4.001 is greater than or equal to -4

Sylvia and her sister are both reading books. Sylvia reads 2 pages every 5 minutes. Her sister reads 3 pages every 6 minutes. What is the difference between Sylvia and her sisters reading rates, in pages per hour? A B. 8 C 24 30
Answer:
6
Step-by-step explanation:
Silvia: 2 pages to 5 minutes
into...
Silvia: 1 page to __ minutes
Find Unit Rate : 5/2= 2.5
Unit Rate for Silvia is 2.5
Written out : 2 pages x 2.5 = 5 minutes
Example : 1 page to 2.5 minutes
What we found : ___ pages to 60 minutes(60 divided by 2.5) is
24 pages to 60 minutesSilvia's sister: 3 pages to 6 minutes
into...
Silvia's sister: 1 pages to ___ minutes
Find Unit Rate : 6/3= 2
Unit Rate for Silvia is 2
Written out : 3 pages x 2 = 6 minutes
Example : 1 page to 2 minute
What we found : ___ pages to 60 minutes(60 divide by 2) is
30 pages to 60 minutesFinal Step : 30 - 24 = 6
find the area of the shaded region below: use 3.14 for pi
a) 33.7 ft
b)134.3 ft
c) 84 ft
d) 50.3ft
In ΔRST, the measure of ∠T=90°, the measure of ∠R=67°, and TR = 94 feet. Find the length of RS to the nearest tenth of a foot......
Answer:
240.6 ft is your answer of your question.
Answer:
240.6 feetStep-by-step explanation:
to understand thisyou need to know about:trigonometryPEMDASlet's solve:to find x we will use cos function
[tex] \quad \: \cos( \theta) = \dfrac{adj}{hypo} [/tex]
substitute the value of [tex]\theta[/tex] and adj:
[tex] \quad \: \cos( {67}^{ \circ} ) = \dfrac{94}{x} [/tex]
cross multiplication:
[tex] \quad \: x\cos(67^{\circ})= 94 [/tex]
divide both sides by cos(67°) :
[tex] \quad \: \dfrac{x \cos( {67}^{ \circ} ) }{ \cos( {67}^{ \circ} ) } = \dfrac{94}{ \cos( {67}^{ \circ} ) } \\ \therefore \: x = 240.6[/tex]

4. On a 3-hour trip, a car travels 156 miles.
What is the average speed of the car on this
trip?
Answer:
v = 52 mph
Step-by-step explanation:
Given that,
The distance travelled by the car, d = 156 miles
Time, t = 3 hour
We need to find the average speed of the car. The formula for the average speed is given by :
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{156}{3}\\\\v=52\ mph[/tex]
So, the average speed of the car is equal to 52 mph.
A crate weighing 2400 N is lifted by a crane
to a platform 5.2 m above the ground. What
is the gravitational PE of the crate?
Answer:
12,480Joules
Step-by-step explanation:
GPE = mass * acceleration due to gravity * height
Since Force = mass * acceleration due to gravity
GPE = Force * Height
GPE = 2400 * 5.2
GPE = 12,480Joules
Hence the gravitational PE of the crate is 12480Joules
