Answer:
The answer is C) Jessica has driven exactly 360 miles out of a total of 400 miles
Step-by-step explanation:
Since 90% is equal to 0.9 of 1
And you need to figure out what statement is true
You would take the largest number from each answer choice and multiply it by 0.9
For Example: In answer choice A), it says Jessica has driven exactly 40 miles out of a total of 360 miles.
So you would multiply 360 by 0.9
Which gives you 324
Which is not 40

Christina Stratton invested $8,000 in a certificate of deposit for 4 years. The certificate earns interest at an annual rate of 6.00 percent compounded quarterly. The amount per $1.00 is 1.061831. What is the effective annual yield ? Show work.
The effective annual yield for a certificate of deposit with a 6% annual interest rate compounded quarterly is approximately 6.14%.
Explanation:To find the effective annual yield, we need to use the formula:
Effective Annual Yield = (1 + (interest rate / number of compounding periods))^number of compounding periods - 1
In this case, the interest rate is 6%, which is equivalent to 0.06. The number of compounding periods is 4 per year. Plugging these values into the formula, we get:
Effective Annual Yield = (1 + (0.06 / 4))^4 - 1
Calculating this, we find that the effective annual yield is approximately 6.14%.

If your percent of discount is 25% and your sales price is $40, what is your original price. Please show me how you got your answer.
The original price before a 25% discount, when the sales price is $40, is calculated as $40 divided by 0.75, resulting in $53.33.
Explanation:To find the original price before a 25% discount, we can set up the equation where original price minus 25% of the original price equals the sales price. Let's call the original price 'P'. Then 0.25P is the amount discounted. The equation is P - 0.25P = $40. This simplifies to 0.75P = $40. To find P, divide both sides by 0.75, giving us P = $40 / 0.75. So, the original price P = $53.33.
The original price is $53.33.
If you have the sales price and the percent of discount, you can calculate the original price using the following steps:
Let P be the original price.Since the discount is 25%, you pay 75% of the original price.We know that 75% of the original price is $40.To find the original price, we set up the equation:
0.75P = 40
Next, solve for P by dividing both sides by 0.75:
P = 40 / 0.75
P = $53.33
So, the original price of the item was $53.33 before the 25% discount was applied.
Which values in P and Q result in an equation with no solutions? Px+5= -4x+Q
Answer:
Given equation: [tex]Px+5 = -4x+ Q[/tex]
Add 4x on both sides we get;
Px + 5 + 4x = -4x + Qc+ 4x
Simplify:
Px +4x + 5 = Q
or
x(P+4) = Q - 5
Divide P+4 on both sides we get;
[tex]x = \frac{Q-5}{P+4}[/tex]
If we set Q-5 = 0 and P +4 = 0, there will be no solutions.
Since, No solution would mean that there is no answer to the equation.
⇒[tex]Q -5 = 0[/tex]
or
Q = 5
and
⇒[tex]P +4 = 0[/tex]
or
P= -4
Therefore, the values of P = -4 and Q = 5 results in an equation with no solutions.
Answer: P = -4 and Q = -5
in a certain city , the hourly wage of workers on temporary employment crontracts is normally distributed. The mean is $15 and the standar deviation is $3. What percentage of temporary workers earn less than $12 per hour?
A) 6%
B) 16%
C) 26%
D) 36%
Answer:
16%
Step-by-step explanation:
The mean is $15 and the standar deviation is $3.
mean = 15 and SD = 3
We need to find percentage less than 12 per hour
P(x<12)= P(x=12)
to find P(x=12) we find z-score
[tex]z= \frac{x-mean}{SD} =\frac{12-15}{3} =-1[/tex]
Now use z-score table . z-score = 0.1587
P(x=12)=0.1587
To get percentage we multiply by 100
0.1587 * 100 = 15.87 = 16%
Trigonometric area formula: Area = 1/2 ab sin (c)

A) 3.9 square units
B) 8.4 square units
C) 11.8 square units
D) 17.7 square units
Answer:
its probably 8.5
Step-by-step explanation:
Answer:
Option B.
Step-by-step explanation:
Trigonometric area formula is Area = [tex]\frac{1}{2}\times absin(C)[/tex]
Where a and b are two sides of the triangle and C is the angle between these two sides.
As given in the figure, side a = 6 units, c = 2√2 units and ∠B = 80°
Then area of the triangle will be defined by the formula
Area = [tex]\frac{1}{2}\times acsin(B)[/tex]
= [tex]\frac{1}{2}\times acsin(B)[/tex]
= [tex]\frac{1}{2}\times 6\times 2\sqrt{2}\times sin(80)[/tex]
= 6√2×sin80°
= 6×(1.414)×0.9848
= 8.36 square units
≈ 8.4 square units
Option B is the answer.

Tony plans to purchase a jacket that costs p dollars. In a week the jacket will go on sale for 30% off. Tony writes althea following expression to calculate the cost of the jacket after the discount:
p - .30p
Now which of the following is equivalent?
1.30p
1.70p
2p - .30
.70p
p (1 - .30)
Answer:
.70p
p(1-.30)
Step-by-step explanation:
Tony plans to purchase a jacket that costs p dollars. In a week the jacket will go on sale for 30% off.
Tony writes althea following expression
p - .30p
Here P or 1P are same
So expression becomes 1p - 0.30p
Both are like terms
so we can subtract it
1p - 0.30p = 0.70p
Also we can write 1p - 0.30p as p(1-0.30)
We can take out p that is in common
Equivalent expression is .70p and p(1-.30)
Samara was playing a game. She wrote down this number sentence to find the total number of points for 11 games in a row. 5 + 7 + 9 + 3 + 1 + 3 + 9 + 8 + 5 + 2 + 3 What's the sum of her scores? 30 35 45 55
Answer:55
Step-by-step explanation: Whenever you see the word "sum" it means to add. So, 5+7+9+3+1+3+9+8+5+2+3=55
By adding each game's score in Samara's game sequence, we find that the total score of all 11 games is 55 points.
Explanation:To find the total score of Samara's games, we need to add all the points she got from each game. We do this by performing the addition of the numbers in the number sentence she wrote down:
First, let's add the first three numbers: 5 + 7 + 9 = 21.Next, let's add the next three numbers to the previous sum: 21 + 3 + 1 + 3 = 28.Then, continue adding the next three numbers to the sum: 28 + 9 + 8 + 5 = 50.Finally, add the last two numbers to the total sum: 50 + 2 + 3 = 55.Thus, the total number of points for 11 games is 55.

What is the measure of 8?
120°
90°
60°
180°
_____________________________
What type of angles are 1 and 5?
vertical
supplementary
corresponding
complementary
Answer:
< 8 = 60
<1 and <5 are corresponding angles
Step-by-step explanation:
<2 = <3 vertical angles
<3 = <6 alternate interior angles
<6 + <8 = 180 supplementary angles
120 + <8 = 180
Subtract 120 from side
120-120 + <8 = 180-120
< 8 = 60
<1 and <5 are corresponding angles
Corresponding angles occupy the same relative position at each intersection.
Answer:
The measure of [tex]\angle 8[/tex] is 60°
[tex]\angle 1[/tex] and [tex]\angle 5[/tex] are corresponding angles.
Step-by-step explanation:
Given that, [tex]m\angle 2= 120\°[/tex]
In the given diagram, [tex]\angle 2[/tex] and [tex]\angle 6[/tex] are corresponding angles and their measures are same.
So, [tex]m\angle 6= 120\°[/tex]
Now, [tex]\angle 6[/tex] and [tex]\angle 8[/tex] are pair of linear angles.
That means......
[tex]m\angle 6+m\angle 8= 180[/tex]°
[tex]\Rightarrow 120\°+m\angle 8=180\°\\ \\ \Rightarrow m\angle 8= 180\°-120\°\\ \\ \Rightarrow m\angle 8=60\°[/tex]
So, the measure of [tex]\angle 8[/tex] is 60°
The type of angles for [tex]\angle 1[/tex] and [tex]\angle 5[/tex] is corresponding.

Step-by-step explanation:
The initial value is another name for the y intercept, so b = 4
Rate of change is another name for slope so m = 2/3
We can use the equation y =mx+b
y = 2/3 x + 4
We want it in function form
f(x) = 2/3x +4
The total cost, including shipping, for ordering five uniforms is $61. The total cost, including shipping, for ordering nine uniforms is $ 105. find the slope.
Answer:39/4
Step-by-step explanation: What I'd do first is set the question up as an ordered pair, for example (x,y) have the uniforms be represented by x and the cost be represented by y. We know that the cost of five uniforms is $66, so we can substitute (x,y) into (5,66). We can then do the same for nine uniforms which is 105 (9,105). The equation we are going to use to find the slope is y2-y1/x2-x1 = 105-66/9-5.
This should result in 39/4. Make sure to always simplify when needed, in this case we don't have to.

The table shows the number of minutes in different numbers of days.
Number of Days 4 7 11
Number of Minutes 5760 10,080 15,840
Which equation expresses the relationship between the number of days, d, and the number of minutes, m?
d = 1440m
m = d + 1440
m=d1440
m = 1440d
Answer:
Last choice
Step-by-step explanation:
Let's assume m is the "y" (dependent variable) and d is the "x" (independent variable) because the number of minutes is larger, and that would make more sense.
5760/4=1440
10080/7=1440
...
Slope is 1440, and it is direct variation
m=1440d
It COULD also be the third choice, but mathematical convention would have us put the coefficient first.
