Alyssa drives 10 miles in 20 minutes. If she drove one hour in total at the same rate, how far did she go?
Answer:
30 miles
Step-by-step explanation:
1 hour = 60 min
60 divided by 20= 3
30 times 10 = 300.
Answer:
She would go 30 miles
This is the answer because 20 minutes times 3 equals 60
which means that 10 times 3 equals 30
so your answer is 30 miles

Answer: 1.35
Step-by-step explanation:
Answer:
1.35
Step-by-step explanation:
We need to identify our independent variables and dependent variables.
The number of papers graded depend on the amount of time.
The amount of time is the independent variable
The papers graded depends us the dependent variable
Divide the independent variable by the dependent variable to find papers per minute
For Ms.Mitchell the papers per minute is
For Mr.Rector, the papers per minute is
Subtract 2.4 from 3.75.
The answer is 1.35

Tyesha found that the z-statistic was 2.1 and that the critical z-values were -1.96 and 1.96. Which of the following is a valid conclusion based on these results?
One can reject the null hypothesis.
One can reject the alternate hypothesis.
One can accept the null hypothesis.
One cannot accept or reject the null hypothesis.
Answer:
Step-by-step explanation:
If the z statistic does not lie within the critical region, you cannot reject the null hypothesis but neither can you necessarily accept it.
What you can do is reject the alternate hypothesis.
The valid conclusion based on the given results is; One can reject the alternate hypothesis.
What is the Conclusion of the Hypothesis?We are told that;
z-statistic = 2.1
Now, the critical z-values were -1.96 and 1.96
Since our z-statistic does not lie within the critical values region, it means that there is not enough evidence to reject the null hypothesis at the given significance level. However, it means that we can reject the alternate hypothesis.

Ray is a member of a card club. He pays a fixed fee of $45. He must pay $6 for every game he attended. He attends 12 games. What is the total amout that he payed
Answer:
$117
Step-by-step explanation:
Create an equation to represent the situation, where x is the number of games he attended, and y is the cost
y = 6x + 45
Solve for the amount he paid by plugging in 12 as x
y = 6x + 45
y = 6(12) + 45
y = 72 + 45
y = 117
So, Ray paid $117

Triangle Q S R is shown. Angle Q S R is a right angle. Altitude s is drawn from point S to point T on side Q R to form a right angle. Side Q S is labeled r and side W R is labeled q. The length of Q T is 10 and the length of R T is 4. What is the value of q? 4 StartRoot 5 EndRoot 2 StartRoot 14 EndRoot 20 StartRoot 5 EndRoot
*The diagram is in the attachment
Answer:
q = 2√14
Step-by-step explanation:
To determine the value of q, apply the leg rule/geometric mean theorem, which is:
Hypotenuse/leg = leg/part
Hypotenuse = 10 + 4 = 14
Leg = q
Part = 4
Plug in the values into the equation:
14/q = q/4
Cross multiply
q*q = 14*4
q² = 56
q = √56
q = √(4*14)
q = 2√14
Answer:
q = 2√14

Answer:
x = 14√3
y = 7√3
Step-by-step explanation:
By applying sine rule in the given triangle,
sin(60°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{\sqrt{3} }{2}=\frac{21}{x}[/tex]
x = [tex]\frac{42}{\sqrt{3}}[/tex]
x = 14√3
By applying cosine rule in the given triangle,
cos(30°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{1}{2}=\frac{y}{x}[/tex]
[tex]\frac{1}{2}=\frac{y}{14\sqrt{3}}[/tex]
y = 7√3
Sergei's car was clocked in a quarter mile race at 146.67 miles per hour.
How many feet per second is this to the nearest hundredth if there are 5280 feet in one mile?
A. 29.33 feet per second
B. 35.99 feet per second
C. 215.12 feet per second
D. 733.35 feet per second
E. 860.48 feet per second
Answer:
C. 215.12 feet per second
Step-by-step explanation:
Sergei's car was clocked in a quarter mile race at 146.67 miles per hour.
How many feet per second is this to the nearest hundredth if there are 5280 feet in one mile?
From the above question
1 mile = 5280 feet
1 hour = 60 minutes
1 minutes = 60 seconds
1 hour = 60 × 60 seconds = 3600 seconds
We are to convert 146.67 miles per hour = feet per second
Hence:
146.67 miles /1 ft × 5280 feet/1 miles × 1 hr/3600 seconds
= 146.67 × 5280 feet/3600 seconds
= 774417.6 feet / 3600 seconds
= 215.116 feet per second.
Approximately = 215.12 feet per second

a small dog’s heart beats about 530,000,000 times during its lifetime, and a large dog’s heart beats about 1.4 times this amount. What is the approximate number of heartbeats in the lifetime of a large dog?
Answer:
I think the answer is 742,000,000
Step-by-step explanation:
The approximate number of heartbeats in the lifetime of a large dog is 742,000,000 times.
What is unitary method?Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
According to the question
A small dog’s heart beats about during its lifetime = 530,000,000 times
A large dog’s heart beats about 1.4 times this amount.
i.e A large dog’s heart beats about during its lifetime = 530,000,000 *1.4 times
= 742,000,000 times
Hence, the approximate number of heartbeats in the lifetime of a large dog is 742,000,000 times.
