Answer the following questions.
(a) What percent of 80 is 44?
(b) What number is 45% of 40?
Answer:
a. 55%
b. 22
Step-by-step explanation:
Answer:
[tex]a)55[/tex]
b) 18
Step-by-step explanation:
→ Set up an for part a
[tex]\frac{80x}{100} =44[/tex]
→ Multiply both sides by 100
[tex]80x=4400[/tex]
→ Divide both sides by 80
[tex]x = 55[/tex]
→ Multiply both numbers together for part b
45 × 40 = 1800
→ Divide the answer by 100
1800 ÷ 100 = 18
Please help my son asked me for this and I don't understand it.
Answer:
y = 2x + 3
Step-by-step explanation:
In the slope-intercept form of the equation of a line,
y = mx + b,
m = slope, and b = y-intercept.
Let's look at Adriana's equation and understand the parts:
y = 2x + 4
y = mx + b
m = slope = 2; b = y-intercept = 4
Now let's look at the description of Henry's equation.
He has the same slope as Adriana, so for Henry, m = 2 also.
His y-intercept is 1 less than Adriana's, so it is 1 less than 4. Henry's y-intercept is 3.
Now that we know that for Henry, m = 2, and b = 3, we can write his equation.
y = mx + b
y = 2x + 3
Answer: y = 2x + 3
Answer:
y=2x+3
Step-by-step explanation:
The answer is gonna be y=2x+3. The 2 is the slope so it needs to stay the same. the 4 in the original equation is the y intercept so to move it one unit lower you just subtract 1 and get your answer
Which of the following angles is corresponding with 25?
02
07
08
04
Answer:
∠7 . However ∠7 and ∠8 are vertical angles which are equal,
Step-by-step explanation:
Angle ∠7, but because ∠7 and ∠8 are vertical angles and they are equal also.
∠5 corresponds to ∠7
m ∠7 = m ∠8 vertical angles are =
I will say ∠7 and ∠8.
The ratio of 70 minutes to 2 hours is
Hey there!
70 minutes
= 1 hour 10 minutes
2 hours
= 60 minutes * 2 minutes
= 60 minutes + 60 minutes
= 120 minutes
70/120
= 70 ÷ 10 / 120 ÷ 10
= 7 / 12
Therefore, your answer is: 7:12 OR 7/12

Which babysitters would charge less than $10 per hour? Select all that apply.
A. Mia charges $34 for 3 hours. This includes a $10 commute fee.
B. Alex charges $66 for 6 hours. This includes a $12 commute fee.
C. Sam charges $92 for 7 hours. This includes a $8 commute fee.
D. Tony charges $52.5 for 3.5 hours. This includes a $0 commute fee.
E. Rene charges $112 for 5.5 hours. This includes a $2 commute fee.
Answer:
A. and B.
Step-by-step explanation:
A. $34 - $10= $24 hourly fee divided by 3= $8 per hour.
B. $66 - $12= $54 hourly fee divided by 6= $9 per hour.
C.$92-$8= $84 hourly fee divided by 7= $12 per hour.
D. $52.5-$0= $52.5 hourly fee divided by 3.5= $15 per hour.
E. $112-$2=$110 hourly fee divided by 5.5= $20 per hour.
So Mia and Alex are the cheapest .

An object is launched directly in the air at a speed of 8 feet per second from a platform located 4 feet above the ground. The position of the object can be modeled using the function f(t)=−16t2+8t+4, where t is the time in seconds and f(t) is the height, in feet, of the object. What is the maximum height, in feet, that the object will reach?
Find the measure of the angle ACD in the given figure???
Answer:
∠ACD = 33.5°
Step-by-step explanation:
The arc length will be twice ∠ ABD,
∠ABD will equal ∠ACD because they subtend the same arc length.
3x + 7 = 2(2x - 6.5)
3x + 7 = 4x - 13
x = 20
∠ABD = (2(20) - 6.5) = 33.5

Please help! Thanks!: If a 95% confidence interval was being calculated using the following expression:
3.2 ± 1.96 ⋅ 1.1
What would be the margin of error for this confidence interval?
If you can please give an explanation on how to solve?
The confidence interval can be calculated from the margin of error, and vice versa,
The margin of error of the confidence interval is 2.156
The confidence interval is given as:
[tex]\mathbf{CI = 3.2 \pm 1.96 \cdot 1.1}[/tex]
The formula of confidence interval is:
[tex]\mathbf{CI = \bar x\pm E}[/tex]
Where E represents the margin of error.
So, by comparison:
[tex]\mathbf{E = 1.96 \cdot 1.1}[/tex]
Multiply
[tex]\mathbf{E = 2.156}[/tex]
Hence, the margin of error of the confidence interval is 2.156
