Answer:
254,000
Step-by-step explanation:
What is 25.4 x 10 to the 4th power?
Translate:
25.4 * 10⁴
25.4 * 10,000
When multiplying numbers by 10s, 100s, 1,000s, and so on, all you have to do is move the decimals left (for dividing) or right (for multiplying). The number of spaces you move the decimal is based on the number of zeros following the 1. For example, *100 means moving the decimal two times to the right, and /100 means moving the decimal two places to the left. No calculator is really needed.Here, we will be moving the decimal four times to the right:
25.4 * 10,000
254,000
Note: if you're not sure, you can always use a calculator to double check :)
Hope this helps!

For which value of h will the equation below
result in an infinite number of solutions?
(3x - 8)h = -27x + 72
Answer:
h = -9
Step-by-step explanation:
Try to make the left hand side and the right hand side equal. By dividing like
h = (-27x+72)/(3x-8)
= [-9(3x-8)]/(3x-8)
= -9
When both sides are equal, you can't find the value of x as there are infinitely many solutions of x.
solve: answer is x is greater than or equal to 3.
Answer:
x ≥ 5
Step-by-step explanation:
[tex]\sf 4x+3\ge \:23[/tex]
subtract 3 from both sides
[tex]\sf 4x+3-3\ge \:23-3[/tex]
simplify
[tex]\sf 4x\ge \:20[/tex]
divide both sides by 5
[tex]\sf \dfrac{4x}{4}\ge \dfrac{20}{4}[/tex]
simplify
[tex]\sf x\ge \:5[/tex]
Answer:
x ≥ 5
Step-by-step explanation:
To simplify the given inequality, we need to isolate the variable "x".
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Step-1: Subtract 3 both sides
4x + 3 ≥ 23
⇒ 4x + 3 - 3 ≥ 23 - 3
⇒ 4x ≥ 23 - 3
⇒ 4x ≥ 20
Step-2: Divide 4 both sides
⇒ 4x ≥ 20
⇒ 4x/4 ≥ 20/4
⇒ x ≥ 5
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
(Note: The solution of the book you provided in your question is incorrect. Seek below for proof)
*answer is x is greater than or equal to 3.*
Substituting 3 in the inequality:
4x + 3 ≥ 23

15 ≥ 23 (False)

f) 45a⁴ - 54a³ = (9a³)(5a - 6)
Step-by-step explanation:
e) 36x² - 32y³ = (4)(9x² - 8y³) becuase 4*9 = 36 and 4*8 = 32
f) 45a⁴ - 54a³ = (9a³)(5a - 6) becuase 9*5 = 45 and 9*6 = 54 and when a is multiplied by a³ you get a⁴

(b) The greatest four-digit number made with the digits 1, 0, 9, 2 is divided by the smallest three-digit number made with 1, 9, 2. Find the quotient and the remainder.
Answer:
Quotient = 70
Remainder = 50
Step-by-step explanation:
The greatest number you can make is 9210, the smallest 3-digit number is = 129.
9210 / 129 = 71 with 50 left
so:
70 is the quotient and 50 is the remainder
help me find Find AB
The distance of AB is 42.04 units, BC is 35.77 units and CA is 34.5 units.
We have,
The length along a line or line segment between two points on the line or line segment.
The coordinates of A are (-18, -18)
coordinates of B are (20, 0)
coordinates of C are (-12, 16)
The formula for distance is Distance=√(x₂-x₁)²+(y₂-y₁)²
Distance AB=√(20-(-18))²+(0-18)²
=√(20+18))²+(0-18)²=√38²+18²
AB=√1444+324
=√1768
=42.04 units
Distance BC=√(-12-20)²+(16)²
=√(-32)²+(16)²=√1024+256
=√1280
=35.77
Distance CA=√(-12-(-18))²+(16+18)²
=√(6)²+(34)²
=√36+1156=34.5
Hence, the distance of AB is 42.04 units, BC is 35.77 units and CA is 34.5 units.

Answer:
799.04
Step-by-step explanation:
First take the area of the rectangle, which would be 50 × 20 = 1000.
Then find the area of the circle. The area of a circle is [tex]\pi r^{2}[/tex]. Since the question says to use 3.14 for pi, your area would be 3.14 × 8².
8² equals 8 × 8 which is 64 and 3.14 times 64 is 200.96.
Since the circle is not part of the shaded area, you subtract the area of the rectangle by the area of the circle. 1000 - 200.96 is 799.04

An employee wants to invest $50,000 in a pension plan. One investment offers 4% compounded quarterly. Another offers 3.75% compounded continuously.
(a) Which investment will earn more interest in 4 yr?
(b) How much more will the better plan earn?
Using compound interest and continuous compouding, it is found that:
a) The investment at 4% compounded quarterly will earn more interest in 4 years.
b) The better plan will earn $537 more.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year.In this problem, the parameters are: P = 50000, r = 0.04, n = 4, t = 4, hence the amount will be of:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]A(4) = 50000\left(1 + \frac{0.04}{4}\right)^{4 \times 4}[/tex]
A(4) = $58,629.
What is the continuous compounding formula?It is given by:
[tex]A(t) = Pe^{rt}[/tex]
In this problem, this option has r = 0.0375, hence:
[tex]A(4) = 50000e^{0.0375 \times 4} = 58092[/tex]
Then:
Item a:
The investment at 4% compounded quarterly will earn more interest in 4 years.
Item b:
58629 - 58092 = $537.
The better plan will earn $537 more.

In a trapezoid, the length of the median is one-half the sum of the lengths of the bases. From this, we have:
[tex] \frac{1}{2} (5x + 7 + 8x - 11) = 63[/tex]

Sam is climbing 9000 m every 30 minutes. How many meters will he climb in 1 hour
Answer:
18000 m
Step-by-step explanation:
Hey there!
In order to solve this problem, we need to first know how many minutes are in an hour
As you know, there are 60 minutes in an hour so this means in 1 hour, he will climb 9000 meters two times
So 9000 two times is 18000,
Meaning, in 1 hour, Sam will climb 18000 m
Answer:
18,000m in an hour
Step-by-step explanation:
We know this because if its 9000 m in 30 minutes, we can do 9000 x 2 and get 18,000m for an hour.
