Answer:
See explanations below
Step-by-step explanation:
We are going to be using the point slope form of equation of a line for all the question, This is expressed as;
y-y0 = m(x-x0)
1) For a straight line is perpendicular to y=2x+5 and passes through (0,3).
Slope of the line m = 2
Slope of the line perpendicular M = -1/m
M = -1/2
Substituting M = -1/2 and the point (0,3) into the equation
y-y0 = m(x-x0)
y - 3 = -1/2(x-0)
y-3 = -x/2
2(y-3) = -x
2y-6 = -x
-x-2y = -6
x+2y = 6
The required equation is x+2y = 6
2) For a straight line is perpendicular to y=0.5x+3 and passes through (3,5).
Slope of the line m = 0.5
Slope of the line perpendicular M = -1/m
M = -1/0.5
M = -2
Substituting M = -2 and the point (3,5) into the equation
y-y0 = m(x-x0)
y - 5 = -2(x-3)
y-5 = -2x+6
y+2x = 6 + 5
y+2x = 11
The required equation is y+2x = 11
3) A straight line is perpendicular to y=4-5x and passes through (20,5).
Slope of the line m = -5
Slope of the line perpendicular M = -1/m
M = -1/-5
M = 1/5
Substituting M = -2 and the point (20,5) into the equation
y-y0 = m(x-x0)
y - 5 = 1/5(x-20)
5(y-5) = x-20
5y-25 = x-20
5y-x = -20+25
5y-x = 5
The required equation is 5y-x = 5
which value is equivalent to
2)

Answer:

Step-by-step explanation:
write number 5 million 4 thousand 3 hundread in standard form
5 million, four thousand, three hundred in standard form is 5.0043 x 10^6
Solution:
Need to represent 5 million, four thousand, three hundered in standard form
5 million = 5000000
4 thousand = 4000
3 hundred = 300
5 million, four thousand, three hundred = 5000000 + 4000 + 300 = 5004300
In standard form, decimal comes after first digit and multiply to power of 10 dependency on total digits of number.
In our case, given number is 5004300.
So we need decimal after first and after that multiplying it by appropriate power of 10. So,
5004300 = 5.0043 x 10^6
Hence 5.0043 x 10^6 is standard form of 5004300 that is standard form of 5 million, four thousand, three hundred.

GUYS PLS HELP!!
all i need to know is what x is please
Answer:
Option C
Step-by-step explanation:
Area of the composite figure = Sum of the areas of three rectangles given
= (3x)(x) + 4x + 3(3x)
= 3x² + 4x + 9x
= 3x² + 13x
Since, area of the figure = 82
Therefore, expression representing area of the figure is,
3x² + 13x = 82
Option (C) will be the answer.
Here, x is a variable.
And we can get the value of x by using quadratic formula.

A company uses the expression 1.03^(2+x) to calculate the total percent increase in the company's operating cost, where x represents the number of years since the company began operating.
Which expression could be used to calculate the same total percent increase in the company's operating cost?
a.) 1.03^2 + 1.03^x
b.) 1.03^2 * 1.03^x
c.) 1^(2 + x) + 0.03^(2 + x)
d.) a^(2 + x) * 0.03^(2 + x)
Answer: is D
Step-by-step explanation:
Answer:
(B)
Step-by-step explanation:
According to exponent rules, a^(x+y) = a^x * a^y:
1.03^(2 + x) = 1.03^2 * 1.03^x
Solution: (B)
27 = 54
value that would make it true
Answer:
2
Step-by-step explanation:
27 = 54,
let's say the value that will make it true is x
So then,
27 * x = 54. If we divide both sides by 27, we have
x = 54 / 27
x = 2
The value that will make it true is multiplying 27 by 2
There are 30 animals up for adoption, and the ratio of fish to hamsters is 1:2 , how many hamsters are up for adoption?
Answer:
20
Step-by-step explanation:
If the ratio of fish to hamster is 1:2 meaning that there are 2 times as much as hamsters than fish. Since I don't know if there is any other animals involved. My guess are that there are 10 fishes and 20 hamsters
Answer: 20 hamsters You're welcome :)
Step-by-step explanation: On the ratio, you would have to plus from the 1 & 2 ratios which, is (10 + 20) equals 30
y = 2x – 1
how do you graph this linear equation???
Answer:
You can choose x as any value like x = 7
if x were to equal 7 then
the equation would be y = 2 times 7 - 1
2 times 7 = 14 and 14-1 = 13
y would be 13 ifi x was 7
so you can graph the point 7,13

The table of values shows the height of a car of a Ferris wheel as it travels in a circular motion. Which statements are true? Select each correct answer.
The car makes a complete revolution in 12 s
The maximum height of the Ferris wheel above ground is 50 yd.
If the car is loaded at 0s, then people are loaded at the lowest height of the Ferris wheel.
The radius of the Ferris wheel is 25 yd
Answer:
The true statements are;
The car makes one complete revolution in 12 s
The radius of the Ferris wheel is 25 yd
Step-by-step explanation:
The values of the table of the given Ferris wheel are presented here as follows;
[tex]\begin{array}{cc}Time \ (seconds) &Height \ (yards)\\0&30\\3&55\\6&30\\9&5\\12&30\\15&55\\18&30\\21&5\\24&30\end{array}[/tex]
From the table, we have;
The time it takes the Ferris wheel to complete a motion round from a height of 30 yards and back to 30 yards which is one revolution = 12 s
∴ The time it takes the car to complete one revolution = 12 s
The maximum height of the Ferris wheel = 55 yards
The lowest height of the Ferris wheel = 5 yards
The time at which the Ferris wheel is at the lowest height = 9 s, and 21 s
If the car is loaded at 0 s, then people are loaded above the lowest height of the Ferris wheel
The diameter of the Ferris wheel = The maximum height of the Ferris wheel - The minimum height of the Ferris wheel
∴ The diameter of the Ferris wheel = 55 yards - 5 yards = 50 yards
The radius of the Ferris wheel, R = 1/2 × The diameter of the Ferris wheel
∴ The radius of the Ferris wheel, R = 1/2 × 50 yards = 25 yards
Therefore, the true statements are;
The car makes one complete revolution in 12 s
The radius of the Ferris wheel is 25 yd.

Jack, Jill, and Bill each carried a 48-fluid ounce bucket full of water down the hill. By the time they reached the bottom, Jack's bucket was only 3/4 full, Jill's was 2/3 full, and Bill's was 1/6 full. How much water did they spill altogether on their way down the hill?
Answer:
76 fl. oz. (see below)
Step-by-step explanation:
With the info:
(Jack) begin: 48 fl. oz.
end: 3/4 of 48 fl. oz.
(Jill) begin: 48 fl. oz.
end: 2/3 of 48 fl. oz.
(Bill) begin: 48 fl. oz.
end: 1/6 of 48 fl. oz.
How much they spilled (sum):
First, find the amounts they spilled individually:
(Jack) (3/4) (48) = how much spilled
= 144/4
= 36 fl. oz.
(Jill) (2/3) (48) = how much spilled
= 96/3
= 32 fl. oz.
(Bill) (1/6) (48) = how much spilled
= 48/6
= 8 fl. oz.
36 + 32 + 8 = 76 fl. oz. spilled
Workout 2/7+1/5 and then simplyfy it
Answer:17/35
Step-by-step explanation:
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(2/7, 1/5) = 35
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(2/7x5/5)+(1/5x7/7)=?
Complete the multiplication and the equation becomes
10/35+7/35=?The two fractions now have like denominators so you can add the numerators.
Then:10+7
——- =17/35
3
This fraction cannot be reduced.
Therefore:2/7+1/5=17/35

in the sequence 1.7, 5.1, 15.3, 45.9, 137.7, ... a geometric sequence?
Answer:
Step-by-step explanation:
A geometric sequence has a common ratio from term to term. Any term divided by the previous term will be a constant, common ratio.
5.1/1.7=3, 15.3/5.1=3, etc So the common ratio is 3 and thus it is a geometric sequence.
