I need help. Find the value of each variable.
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

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

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

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.

Answer
Exterior,18°
Interior,162°
Step-by-step explanation:
To calculate exterior,360°÷no of sides, i.e
360°÷20=18°
Interior is gotten by 180°-exterior angle
180°-18°=162°
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.

Which of the following is closest to the distance that the tip of the hand travels as it moves from
the 12 to the 3?
Answer:H
Step-by-step explanation:
The distance that the tip of the hand travels as it moves from the 12 to the 3 will be 15.7143 cm.
What is an arc?An arc is a smooth curve that joins two endpoints. The arc is mostly referred to as a part of the circle.
As it is given that the length of the hand of the clock is 10 cm, and the movement of the hand of the clock is from 12 to 3 therefore, the movement is about 90°.
Now, if we see the movement of the hand of the clock it will be along the arc of the circle, therefore, the length of the arc with a radius of 10 cm and angle of 90° can be written as,
[tex]\text{Length of the arc} = 2\pi r \times \dfrac{\theta}{360^o}[/tex]
[tex]= 2 \times \pi \times 10 \times\dfrac{90}{360}\\\\= 2 \times \pi \times 10 \times\dfrac{1}{4}\\\\= 15.7143\rm\ cm[/tex]
Hence, the distance that the tip of the hand travels as it moves from the 12 to the 3 will be 15.7143 cm.

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
