The density of gold is 19.3 g/cm?
A gold bar has volume 150 cm
Work out the mass of the gold bar.
Answer:
2895 grams
Step-by-step explanation:
Use the density formula, d = m/v, where m is the mass and v is the volume.
Plug in the density and volume into the formula, and solve for m:
d = m/v
19.3 = m/150
Multiply each side by 150:
2895 = m
So, the mass is 2895 grams

The flashlight you are using to find your phone is a green flashlight which isn't good for finding things in the dark. You decide to go grab your yellow flashlight instead. Which wave property differs in the two flashlights causing this difference in color? Explain.
Answer:
their wavelength
Explanation:
A wave refers to disturbances or vibrations that travel from one medium or vacuum to another in an organized way, while wavelength refers to the distance between two consecutive peaks of waves.
For example, the wavelength of green light is 550nm (nanometre), while that of yellow light is 580nm (nanometre).
This difference in the color of the flashlights is visible to the human eyes because the human eye is believed to be able to detect any wavelengths of light from 700 nanometres to about 400 nm for violet light.

A car can travel 156 kilometers on 13 liters of gasoline. How much gasoline will it need to go 480 kilometers?
Answer:
40
Step-by-step explanation:
To find how much gasoline is needed for 480 kilometers, we will need to find how much is needed per kilometers:
13 liters is used for 156 kilometers
156/13 = 12 so 1 liter gasoline is spent per 12 kilometers
So for 480 kilometers we would need 40 liter gasoline because
480/12 = 40

Answer:
-14
Step-by-step explanation:
Of course, 910 divided by 65 is 14, but since 65 was negative, the answer must be negative. If both numbers were negative, then it would be positive, but in this case, it would be negative as 65 was negative.

Solve 4/y = 2/11.
The solution is y=__ ?
Answer:
See below.
Step-by-step explanation:
4/2=2
2*11=22
y=22
-hope it helps
Answer:
22
Step-by-step explanation:
4/22 is equivalent to 2/11 because 2/11 is 5 and a half times 2. So the second one has to be 5 and a half times 4. So the answer is 4/22.
What is the value of y?
A.
16
B.
48
C.
64
D.
13
Answer:
48°
Step-by-step explanation:
Because the y° angle plus the 3x° angle should equal 90°.
subtract 48° from 90° and you will get 42°.
the 3x° angle looks like it would be acute so it'd have to be 45° or under.

Helpppp pls this involves compound interest
Answer:
[tex]f(x)=9500(1.0625)^x[/tex]
Step-by-step explanation:
Formula for compound interest / exponential functions:
[tex]f(x)=a(b)^x[/tex]
a represents the initial value, b represents the multiplier, and x is the duration / inputs.
In this case, 9,500 is the amount invested, so that's the initial value. The factor here is 6.25% which turned into a decimal is 0.625, but we have to add 1 to that since we have to include the original 100% from when we invested the $9,500. Lastly, x is the number of years, so that remains the same as the formula.

1. The first three terms and the last term of a finite arithmetic sequence are - 92,- 88. -
84, ...,12.Find the number of terms in the sequence.
A. 20
B. 25
C. 27
D. 30
The number of terms in the given arithmetic sequence is 27 so option (C) will be correct.
What is Arithmetic progression?The difference between every two successive terms in a sequence is the same this is known as an arithmetic progression (AP).
The arithmetic progression has wider use in mathematics for example sum of natural numbers.
Natural number = 1,2,3,4,5,6,7,8...
Now it has the same difference between any two consecutive terms d =2-1 = 3-2
Given the AP;
- 92,- 88, -84, ...,12.
First term (a) = -92
Common difference(d) = -88 + 92 = 4
The nth term or last term = 12
Nth term is given as ;
⇒ a + (n - 1)d
12 = -92 + (n - 1)4
n - 1 = 26
n = 27
Hence "The number of terms in the given arithmetic sequence is 27".
