Answer:
1. d ≈ 19
2. a ≈ 39.00°
3. x ≈ 37°
Step-by-step explanation:
1) Using sine to find d, recall that sine = opposite side/hypotenuse. So:
[tex]sin(39) = \frac{d}{30}[/tex]
Cross multiply:
d = 30 (sin(39))
d ≈ 19
2) To find the measure of the angle, we can use sine because we have the opposite side and hypotenuse measures. So:
[tex]sin(a) = \frac{18.88}{30}[/tex]
Using the inverse of sine:
[tex]a = sin-1(\frac{18.88}{30})[/tex]
Input into calculator:
a ≈ 39.00°
3) To find the measure of the angle, we can use tangent because we have the opposite side and adjacent side measures. So:
[tex]tan(x) = \frac{300}{400}[/tex]
Using inverse of tangent:
[tex]x = tan-1 (\frac{300}{400})[/tex]
Input into calculator:
x ≈ 37°

Is 3(5x - 4) = 15x - 12 a one solution , no solution or infinite solutions
Answers
Answer:
Infinite Solutions
Step-by-step explanation:
3(5x - 4) needs to be simplified
So we multiply 5x by 3
So 3 x 5x = 15x
Then we multiply -4 by 3
3 x -4 = - 12
Put those together we get 15x - 12
The same equation as the one on the right side
So since 15x - 12 = 15x - 12, the x variable can be any number

Susie's dog is 2feet tall. When she measures her dog in inches he was 24 inches. Why is there an increase in inches
Answers
Given:
Susie's dog is 2 feet tall. When she measures her dog in inches he was 24 inches.
To find:
Why is there an increase in inches.
Solution:
It is given that Susie's dog is 2 feet tall.
We know that,
1 feet = 12 inches
Using this conversion, we get
2 feet = 2×12 inches
2 feet = 24 inches
So, the measures 2 feet and 24 inches are equal.
Therefore, if Susie's dog is 2 feet tall then he is 24 inches tall because both of these measure are equal.

Think About the Process A jar contains only pennies, nickels, dimes, and quarters. There are 17 pennies, 12 dimes, and 26 quarters. The rest of the coins are nickels. There are 66 coins in all. How many of the coins are not nickels? If n represents the number of nickels in the jar, what equation could you use to find n?
_____ of the coins are not nickels.
Answers
Answer:
Number of coins that are not nickels = 55 coins
66 = 55 + n
number of nickels in the jar = 11
Step-by-step explanation:
Pennies = 17
Dimes = 12
Quarters = 26
Nickels = n
Total coins = 66
How many of the coins are not nickels?
= Pennies + Dimes + Quarters
= 17 + 12 + 26
= 55 coins
Number of coins that are not nickels = 55 coins
what equation could you use to find n?
Total coins = Pennies + Dimes + Quarters + nickels
66 = 17 + 12 + 26 + n
66 = 55 + n
n = 66 - 55
n = 11
number of nickels in the jar = 11

Studies show that people who live in very cold climates have a 30% chance of getting influenza and a 15% chance of getting appendicitis during the winter. What is the probability a person has both diagnoses, rounded to the nearest percent?
Answers
Answer: The probability a person has both diagnoses = 4.5%
Step-by-step explanation:
Given: Chances of getting influenza = 30% = 0.30
Chances of getting appendicitis = 15% = 0.15
Since both the events are independent , so the probability a person has both diagnoses will be
P(influenza and appendicitis) =P(influenza) x P(appendicitis)
[tex]=0.30\times0.15\\\\=0.045\\\\=4.5\%[/tex]
Hence, the probability a person has both diagnoses = 4.5%

In a pair of complementary angles, the measure of the larger angle is twice that of the smaller
angle. What is the measure of the larger angle?
A 30°
B 60°
C 90°
D 120°
Answers
Answer:
D. 120°
Step-by-step explanation:
Complementary angles have a sum of 180 and since its twice the measure of the smaller one so the smaller one would have to be 60 in order for the bigger one to be 120 because you then add your two angles and it should make 180
Answer:
Step-by-step explanation:
Supplementary angles sum to 90. We are told the larger angle is twice the smaller.
L=2S, S=L/2
S+L=90, using S=L/2 we have
L/2+L=90
(3L)/2=90
3L=180
L=60
