Answer:
The cosine of the complementary angle to 38° is 0.62. Answer: d
Explanation:
Complementary Angle
Two angles x and y are complementary if
x+y=90°
The complementary angle of 38° is 90°-38°= 52°
Now use a calculator to find the approximate value of
[tex]\cos 52^\circ \approx 0.61566[/tex]
Rounding to two decimal places:
[tex]\cos 52^\circ \approx 0.62[/tex]
a. Incorrect. The cosine of 52° is not 0.68
b. Incorrect. The cosine of 52° is not -0.16
c. Incorrect. The cosine of 52° is not -0.22
d. Correct. The cosine of 52° is 0.62 to two decimal places.

Your school band needs to buy new recording equipment. The equipment will cost $3000. The band has collected $1200 in previous fundraisers. If the band sells sandwiches at $5 each, how many sandwiches will they need to sell to raise remaining funds?
Answer:
360
Step-by-step explanation:
Total amount needed = $3000
Amount available = $1200
Remaining amount = Total amount needed - Amount available
= $3000 - $1200
= $1800
If the band sells sandwiches at $5 each, how many sandwiches will they need to sell to raise remaining funds
Number of sandwiches to sell = Amount remaining / price of sandwiches
= $1800 / $5
= 360
Therefore, the band will need to sell 360 sandwiches to raise remaining funds
Wha is 3x+3y=-9 in standard to slope intercept form simplified, thank you!
Answer
Step-by-step explanation:
The answer would be y=-x-3. 3x+3y=-9 is in standard form and you want it to be in y=mx=b form (slope-int) so subtract 3x by both sides. Now, you have 3y=-3x-9. Divide 3 to both sides, now you will get y=-x-3.
can you plz help me with this 2.25f+5=13.5f+14
Answer:
F=10
Step-by-step explanation:
Add 13.5 and 14 to get 27.5.
2.25f+5=27.5
Subtract 5 from both sides.
2.25f=27.5−5
Subtract 5 from 27.5 to get 22.5.
2.25f=22.5
Divide both sides by 2.25.

Tamara earns her living as a salary plus commission employee. Her annual salary is $48,000, and she earns 4% commission on all sales she makes. If Tamara wants to make a total of $6,000 this month, how much in sales does she need to have? a. $30,000 b. $50,000 c. $100,000 d. $150,000 Please select the best answer from the choices provided
Answer:
b. $50,000
Step-by-step explanation:
The computation of the sales amount need to have is shown below:
But before that monthly income is
= Annual salary ÷ Number of months
= $48000 ÷ 12
= $4,000
Now the equation could be made which is shown below:
0.04x = $6,000 - $4000
0.04x = $2,000
X = $2000 ÷ 0.04
X = $50,000
Hence, the correct option is b. $50,000

Answer:
x > 1.167 (rounded to the nearest thousandth)
Step-by-step explanation:
Original Equation:
6x - 3 > 10
Add 3 to both sides
6x > 7
Divide both sides by 6
x > 1.1666666. . .

4x+13x=119 what does x=?
x=7
Answer:
x = 7
Step-by-step explanation:
Given
4x + 13x = 119 ( collect like terms on left side )
17x = 119 ( divide both sides by 17 )
x = 7
Answer:
x=7
Step-by-step explanation:
Let's solve your equation step-by-step.
4x+13x=119
Step 1: Simplify both sides of the equation.
4x+13x=119
(4x+13x)=119(Combine Like Terms)
17x=119
17x=119
Step 2: Divide both sides by 17.
17x
17
=
119

QUESTION 1: True or false:
Do vertical angles prove parallel lines?
QUESTION 2:
Solve for x in the diagram below. PIC ATTACHED
Answer:
1.Yes, vertical angles prove lines parallel if there is a transversal and the corresponding vertical angles are congruent
2. x= 12
Answer:
1. In order to use Theorem 10.7, you need to show that corresponding angles are congruent. You can use the fact that ∠1 and ∠2 are vertical angles, so they are congruent. Because ∠2 and ∠3 are corresponding angles, if you can show that they are congruent, then you will be able to conclude that your lines are parallel.
In response to a gss question in 2006 about the number of hours spent per day watching television, the responses by the fifteen subjects who identified themselves as Buddhist were 0, 0, 0, 1, 1, 1, 2, 2, 2, 2, 2, 3, 4, 4, and 5. For these fifteen subjects, the mean number of hours spent per day watching television is 1.93 hours. What is the standard error of this mean estimate?
Answer:
Standard error = 0.4
Step-by-step explanation:
Step 1
We find the Standard Deviation
The formula = √(x - mean)/n - 1
n = 15
Mean = 1.93 hours
= √(0- 1.93)² + (0-1.93)² +(0- 1.93)²+( 0- 1.93)²+ (1- 1.93)² + (1- 1.93)² +(1 - 1.93)² +(2 - 1.93)² + (2 - 1.93)² + (2 - 1.93)² + (2 - 1.93)² + ( 2 - 1.93)² +(4 - 1.93)² +(4 - 1.93)² + (5 - 1.93)²/15 - 1
= √(3.737777776 + 3.737777776 + 3.737777776 + 0.871111111 +0.871111111 + 0.871111111 + 0.004444444445+ 0.004444444445 + 0.004444444445 + 0.004444444445 + 0.004444444445 + 1.137777778 + 4.271111112 + 4.271111112 + 9.404444446)/15 - 1
= √2.352380952
= 1.533747356
Step 2
We find the standard error
The formula = Standard Deviation/√n
Standard deviation = 1.533747356
n = 15
= 1.533747356/√15
= 1.533747356 /3.87298334621
= 0.39601186447
Approximately = 0.4
Therefore, the standard error is 0.4
Sorry if this is too big just one on answer would help.
Answer:
The rate of change or the slope is 4/1 or just 4.
Step-by-step explanation:
To find the rate of change, you have to figure out the distance between the y values and x values.
The distance from 6 to 10 for number 1 is 4, and it continues with the same pattern of 4!
The distance in the x values for number one is just 1! It stays as one for the entire table.
Now we put our information in a fraction.
Y is always over X. Y/X
4/1 or just 4.
Lastly, I'm a bit confused on what exactly it means by Start value but I'm sure you can email your teacher about that.

If 6 pounds of blueberries costs $16.50, is $1 for 2.75 pounds of blueberries true?
Step-by-step explanation:
Hmm I'm not sure but (no) I think
6 pounds = $16.50
1 pound = $16.50 ÷ 6
=$2.75
$16.50 = 6 pounds
$1 = 6 ÷ $16.50 = 4/11 pounds (0.36363636......)
