The speed of light is about 300,000 kilometers per second. The Sun is about 93 million miles from Earth. How many minutes does it take for the sunlight to reach Earth? Round to the nearest tenth if necessary.
Answer: 8.3 minutes
Step-by-step explanation:
1 mile is to 1.60934km so 93 million miles is:
= 93 * 1.609
= 149,637,000 km
Travelling at 300,000 km per second, the number of seconds it takes is:
= 149,637,000/300,000
= 498.79 secs
In minutes this is:
= 498.79/60
= 8.3 minutes
How does the graph of the function f(x) = 2x4− 3 differ from the graph of its parent function? Select all the transformations.
◻A.The graphs are the same.
◻B.Subtracting 3 translates the graph down 3 units.
◻C.The leading coefficient, 2, stretches the graph vertically.
◻D.Subtracting 3 translates the graph up 3 units.
◻E.Subtracting 3 translates the graph right 3 units.
Answer:
B and C are the correct options
Step-by-step explanation:
The parent function here will be ;
f(x) = x^4
Multiplying x^4 by 2 means that we are having a vertical stretching
What this means is that the leading coefficient 2 stretches the graph vertically by 2 units
Subtracting -3 means that we are translating the graph down by a value of 3 units
So the correct options are;
B and C
Write in slope-intercept form an equation of the line that passes through the points (−4, 2) and (6,−3).
Answer:
y = -0.5xStep-by-step explanation:
[tex]\bold{slope\, (m)=\dfrac{change\ in\ Y}{change\ in\ X}=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]
(−4, 2) ⇒ x₁ = −4, y₁ = 2
(6,−3) ⇒ x₂ = 6, y₂ = −3
So the slope:
[tex]\bold{m=\dfrac{-3-2}{6+4}=\dfrac{-5}{10}=-0.5}[/tex]
The point-slope form of the equation of the line passing through point (x₀,y₀) and with slope m is: y - y₀ = m(x - x₀)
m = -0.5
(−4, 2) ⇒ x₀ = −4, y₀ = 2
Therefore:
y - 2 = -0.5(x - (-4))
y - 2 = -0.5x - 2 {add 2 to both sides}
y = -0.5x ← the slope-intercept form of the equation (b=0)

Kayla gets paid $15 to rake the lawn. Kayla gets paid 3 times as
much to rake the lawn as she does to mow the lawn. How much
does Kayla get paid to mow the lawn?
Answer:
$5
Step-by-step explanation:
The opposite of multiplication is division.
$15/Raking = 3 times more pay than mowing the lawn.
Divide $15/Raking by 3 and you'll get the pay for mowing the lawn.
15/3 = 5
Answer:
5
Step-by-step explanation:
From the expressions below, select the one that results in a negative difference.

A $30 shirt is marked, "Get 25% off." What is the sale price of the shirt?
Answer:
$22.50
Step-by-step explanation:
First, we find how much we need to take off so our equation is:
30 x 0.25 = 7.5
So, we take 7.5 off of 30 which is:
30 - 7.5 = 22.5
So, the shirt is selling for $22.50
Hope this helps:)
If frank have 395 marbles he putting in putting 22 in each bag how many marbles will he have in the bags that is not full
Answer:
21 bags are not full.
Step-by-step explanation:
Given that,
Total no. of marbles = 395
He is putting 22 marbles in each bags.
We need to find the number of marbles will he have in the bags that is not full. It can be calculated by dividing total no. of marbles and the no. of marbles in each bags.
[tex]x=\dfrac{395}{22}\\\\=17.95\\\\\text{or}\\\\=17\dfrac{21}{22}[/tex]
So, it means 17 bags are full but 21 bags are not full.

Answer:
a. x = 5, AB = 14, BC = 8
Step-by-step explanation:
✔️Both triangles are similar, therefore their side lengths are proportional to each other.
Thus:
[tex] \frac{2x + 4}{x + 3} = \frac{7}{4} [/tex]
Cross multiply
[tex] 4(2x + 4) = 7(x + 3) [/tex]
[tex] 8x + 16= 7x + 21 [/tex]
Collect like terms
[tex] 8x - 7x = -16 + 21 [/tex]
[tex] x = 5 [/tex]
✔️AB = 2x + 4
Plug in the value of x
AB = 2(5) + 4
AB = 14
✔️BC = x + 3
Plug in the value of x
BC = 5 + 3
BC = 8
Determine the value of x in the diagram.

-1/5x≤8
what is the aswer
Hey there!
“-1/5x ≤ 8”
MULTIPLY both sides by -5
-1/5x × -5 ≤ 8 × 5
CANCEL out: -1/5 × -5 because that gives you 1
KEEP: 8 × 5 because that helps us solve for your given equation
NEW EQUATION: x ≥ 8 × 5
8 × 5 = 40
Answer: x ≥ 40

Step-by-step explanation:
All square angles are 90° exactly 90° so we can use that to your advantage. since "7x + 3" is one of the square's angles, that means 7x + 3 must equal 90°. (7x + 3)° = 90°.
7x + 3 = 90
7x = 90 - 3
7x = 87
7x/7 = 87/7
x = 87/7
