Answer:
g(4a) = 8a^2 -20a +3.5
Step-by-step explanation:
Put 4a where x is and simplify.
g(x) = 0.5x^2 -5x +3.5
g(4a) = 0.5(4a)^2 -5(4a) +3.5
= 0.5(16a^2) -20a +3.5
g(4a) = 8a^2 -20a +3.5

Find the length of YZ
Answer:
[tex]YZ = 19cm[/tex]
Step-by-step explanation:
To figure out what line YZ equals, we must first find x. And to do this, let's set up an equation.
Firstly, we know that XY is 8cm, and XZ is 4x+3. So, we know that XY + YZ will equal XZ. Let's set that up:
[tex]8 + 2x+7=4x+3[/tex]
Combine like terms.
[tex]2x+15=4x+3[/tex]
Subtract 2x from both sides.
[tex]15=2x+3[/tex]
Subtract 3 from both sides.
[tex]12=2x[/tex]
Divide both sides by 2.
[tex]6=x[/tex]
Now, we just need to plug 6 into the equation of YZ.
[tex]2(6)+7[/tex]
[tex]12+7[/tex]
[tex]YZ = 19[/tex]

On Tuesday, a local hamburger shop sold a combined total of 402 hamburgers and cheeseburgers.
The number of cheeseburgers sold was two times the
number of hamburgers sold.
How many hamburgers were sold on Tuesday?
I hamburgers
Answer:
134
Step-by-step explanation:
2x +x =402
3x=402
x=134
2x=268
In this case x = hamburgers and 2x = cheeseburgers. And sense x = 134 that is your answer.

Answer:
To a whole number: Add the numbers in the ratio togetherTo a fraction: Each number in the ratio would become a numerator in a fractionI hope this helps!
Credit goes to: calculatorsoup.com
Answer:
To convert, start by adding both parts of the ratio together. This will be the denominator for each of the fractions and also represents the whole set. Then, each part of the ratio creates a fraction, with the numerator being the first part of the ratio and the denominator being the sum that was just found.

A hot air balloon is released at ground level, and it rises into the air at a constant rate. After 5 seconds the height of the balloon is 20 feet. The balloon continues to rise at the same rate.
Which table shows the relationship between the time in seconds, x , and the height of the balloon in feet, y?
Answer: D
Step-by-step explanation:
If after 5 seconds the height was 20 feet then in 10 seconds it will be 40 feet and in 20 seconds it will be 80 seconds.
To get from 5 to 10 you multiply by 2
To get from 20 to 40 you multiply by 2.
Since you have a constant change then it works for D only.
The linear equation that represents the height of the balloon at a time will be y = 4x. Then the correct option is D.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
A hot air balloon is launched from the ground and climbs into the air at a consistent velocity. The balloon's elevation is 20 feet after 5 seconds. The balloon keeps rising at the same rate.
The height per second is given as,
m = 20 / 5
m = 4 ft/sec
Then the equation is given as,
y = 4x
At x = 10 sec, then the value of y will be
y = 4 (10)
y = 40 ft
At x = 20 sec, then the value of y will be
y = 4 (20)
y = 80ft
The linear equation that represents the height of the balloon at a time will be y = 4x. Then the correct option is D.

A city starts with a population of 200,000 people in
2005. The population has been declining according to
the equation
P(t) = 200,000e-.08
where P is the population t years later. Approximately
when will the population be half the initial amount?
Answer:
200,000 and 2005 which cant theoretically be done be P(t) which would increase in the population which would most likely be from 2005 to 2020. so you cannot do this because imagine it as X=(Y)x the mass of population which would be defined as (P) which will also be represented as a probable and physical change in the number. but not only the number, but the population. being have of the initial amount which you will take the variable (P) and have the exact amount which would be the population. Which would theoretically recon as a positive ID of the population.-Cj
Step-by-step explanation:
Mikes home street address number has 5 digits . Two digits have values of 50,000 and 200 . The digits in the ones place is 3 . The value of each of the other digits is ten times the value of the digits on its right . What is mikes home street address number ?
Answer: Mikes home street address number = 52233
Step-by-step explanation:
We need to make a 5 digit number such that
Two digits have values of 50,000 and 200 .
The digits in the ones place is 3 .
Now number is like 50,000 +x + 200 + y + 3 (ten thousand > thousand > Hundred > tens > ones )
Need values for : thousands place and tens place
The value of each of the other digits is ten times the value of the digits on its right .
thousands place value (x)= 200 x 10 = 2000
tens place value (y)= 3 x 10 =30
Required number = 50,000 +2000 + 200 + 30+ 3 = 52,233
∴Mikes home street address number = 52233

(14 POINTS!) Based On the information in the table, is the cost of the apples proportional to the weight of apples ?
Answer:
yes it is proportional, if you subtract 3.76 from 5.64 you get 1.88 then add 1.88 to each number to make sure it's right.
Answer:
The statement of whether the cost is proportional to the cost and weight of apples is: yes, it is proportional.
Step-by-step explanation:
From what I can find out from the graph, I would firstly likely want to see if there is a constant between each pound and cost. Meaning, I would want to see if there is a rule that is used throughout the table.
From what I had found out, the rule of this table is:
(x = pounds of apples)
(y = cost of apples)
y = 1.88x
This means that in order to get the 'y' value, also known as the cost of apples, we must multiply 1.88 to the 'x' values, pounds of apples.
This can be found by:
First, dividing 3.76 to 2, your quotient is: 1.88
[tex]\frac{3.76}{2}=1.88[/tex]
Then we need to see if this applies to the other terms as well by multiplying 1.88 to each 'x'
y = 1.88x
y = 1.88(3) = 5.64
y = 1.88(4) = 7.52
y = 1.88(5) = 9.4
You get the same vaule, which means that this is proportional to the table provided.

Derek is watching a thunderstorm. He hears the thunder 4.7 s after seeing a flash of lightning. How far away was the lightning?
Answer:
1.0014 Miles
Step-by-step explanation:
The light travels at 186,291 miles per second (~300,000 km/s), and speed of sound in dry air is equal to 0.21 - 0.22 miles per second (0.33-0.35 km/s), as it varies with the temperature. We can notice the lightning almost immediately even though the storm is far from us, but the thunder needs around 5 seconds to travel one mile and approximately 3 seconds to travel one kilometer. Thanks to this seven orders of magnitude difference in sound and light propagation, we can easily estimate the storm distance

The difference in rainfall between the wettest and the driest months is inches.
Answer:
The difference is 3.97 inches of rainfall
Step-by-step explanation:
Here, we want the difference between the wettest and driest months.
From the question, we can see that the wettest month has a rainfall height of 2.3 inches
The driest month has a rainfall of -1.67 inches
So the difference between the two will be;
2.3 - (-1.67)
= 2.3 + 1.67 = 3.97 inches

An angle measures 86° less than the measure of its complementary angle. What is the measure of each angle?
[tex]x + (x - 86) = 90[/tex]
[tex]2x - 86 = 90[/tex]
Both sides plus 86
[tex]2x = 90 + 86[/tex]
[tex]2x = 176[/tex]
Divided both sides by 2
[tex]x = \frac{176}{2} \\ [/tex]
[tex]x = 88[/tex]
So the angles are :
[tex]88 \: \: \: \: \: and \: \: \: \: 2[/tex]
The measure of the two complementary angles are 88° and 2°.
What is a complementary angle?"When the sum of two angles is 90°, then the angles are known as complementary angles."
Let, the complementary angle of the mentioned angle is x.
Therefore, the angle is = (x - 86°)
Now, x + (x - 86°) = 90°
⇒ 2x - 86° = 90°
⇒ 2x = 176°
⇒ x = 88°
Therefore, the measured angle is 88°.
It's complementary angle is = (90° - 88°) = 2°.
