Answer:30
Step-by-step explanation:
Find the value of cos 45° + sin 30° Solution: Given, cos 45° + sin 30° cos 45° + sin
30° = 1/√2 + ½ = (√2+1)/2 Question 2: Evaluate: 2 sin 60° – 4 cos 45° Solution: Given, 2 sin 60° – 4 cos 45° Since, sin 60° = √3/2 and cos 45° = 1/√2
Therefore, ⇒ 2 (√3/2) – 4 (1/√2) ⇒ √3 – 2√2 Question 3: Find Cos 45 + Cos 90. Solution: Cos 45° = 1/√2 Cos 90° = 0 Therefore, Cos 45° + cos 90° = 1/√2
The difference of 10 times a number and 75 is
the opposite of 625. What is the number?
Pls Help
Answer:
-55
Step-by-step explanation:
Assuming the opposite of 625 means -625, the equation to solve is [tex]10x-75=-625[/tex] where x represents the number.
Adding 75 to both sides of the equation:
[tex]10x=-550[/tex]
Dividing both sides by 10:
[tex]x=-55[/tex]

A)north
B)south
C) east
D) west
Answer:
Step-by-step explanation:

Jacob helped his grandma peel potatoes for the family's dinner. His grandma peeled 4 times as many potatoes as Jacob peeled.If Jacob's grandma peeled 16 potatoes, how many potatoes did they peel altogether?
Answer: 20
Step-by-step explanation:
Jacob's grandma peeled 4 times as many potatoes as he did, so if she peeled 16, you would divide 16 by 4 and conclude that Jacob peeled 4 potatoes. Then, you would add the 4 potatoes that he peeled to her 16. Hope this helps!
Jacob and his grandmother both peeled 20 potatoes.
What is the ratio?A ratio is a numerical comparison of two numbers. A ratio represents the proportion of one object to another.
Given, Jacob's grandmother peeled four times as many potatoes as he did, therefore if she peeled 16, divide 16 by four to get that Jacob peeled four potatoes. Then you'd add the four peeled potatoes to her 16.
potato peeled by Jacob's grandmother = 16
potato peeled by Jacob = 4
Total potatoes peeled = 16 + 4 = 20
Therefore both Jacob and his grandmother peeled the sum of 20 potatoes together.

Find the measure of angle b.
And show work
Answer:
From the above attachment we can conclude that the sum of the angle 'b' and 40° is 90° (right angle)
[tex]b + 40 ^\circ = 90 {}^{ \circ} \\ b = 90 {}^{ \circ} - 40 {}^{ \circ} \\ \boxed{ b = 50 {}^{ \circ} }[/tex]
b = 50° is the right answer.The measure of one EXTERIOR angle of a regular
polygon is 13.8 degrees. How many sides does it have?
The number of sides of the regular polygon is 26
The formula for calculating the exterior angle of a regular polygon is expressed as:
Exterior angle of a polygon = 360 ÷ number of sides.
Given the following:
Exterior angle of a regular polygon = 13.8 degrees
Required
Number of sides
Substitute the given parameters into the formula as shown:
Exterior angle of a polygon = 360/13.8
Exterior angle of a polygon = 26.08
This means that the number of sides of the regular polygon is 26

Paisley needs to order some new supplies for the restaurant where she works. The restaurant needs at least 587 glasses. There are currently 307 glasses. If each set on sale contains 20 glasses, which inequality can be used to determine the minimum number of sets of glasses Paisley should buy?
as a equation please
Answer:
The restaurant needs at least 587 glasses
587-307 = 280
each set contains 20 glasses
14 sets contain 280 glasses
let the minimum number of sets be x
x ≥ 14
The inequality represents the minimum number of sets of glasses Paisley should buy is 14 ≥ x.
The relationship between two or more expressions that is either greater or less than each other but not equal to each other is called inequality.
Given that:
Number of glasses the restaurant needs = 587
Number of glasses the restaurant has = 307
Since each set contains 20 glasses, the total number of glasses in "x" sets would be 20x.
The equation can be set as:
Total glasses needed ≥ Current glasses + Glasses in sets to buy
Substitute the values in the above inequality:
587 ≥ 307 + 20x
280 ≥ 20x
14 ≥ x
The inequality represents the minimum number of sets of glasses Paisley should buy is 14 ≥ x.

Round your answer to a whole number.
Explain one way you can tell these lines are parallel.
Plz help, and Paragraph or sentences
If the slope is the same but they have 2 different y-intercepts, the lines are parallel.
Remember that y=mx+b, where m is slope and b is y-int, y and x are variables.
Example:
y=3x+5 and y=3x+1
Parallel because the slope is the same.
y=3x-2 and y=2x-1
NOT parallel because the slope is different.
