2cos60° + 3sin-45° - 3sin30° + 2cos90°
= 2 × 1/2 + 3 × -1/√3 - 3 × 1/2 + 2 ×0
= 1 - 3/√3 - 3/2 + 0
= 1 - 3/√3 - 3/2
= 1 - 3/1.732 - 1.5. <----> ( √3 = 1.732 )
= 1 - 1.732 - 1.5
= -2.232

Rachel runs 4 miles in 23 minutes. How many miles does she run per minute?
Answer:
To calculate how many total miles Rachel runs per minute, setting up a unit rate, that is a rate with a denominator of 1, would be helpful.
Step-by-step explanation:
Use the current problem to determine a rate.
23 minutes/4 miles
Now, set up a unit rate.
1 minute/x miles = 23 minutes/4 miles
To solve for x, we can use simple division strategies. We divide 23 by 23 to receive 1 minute. Likewise, dividing the current milage by 23 would wield the correct unit rate. To do this, divide 4 by 23.
4/23 = 0.1739130434782609
Finally, simplify your answer to receive 0.17.
Therefore, Rachel runs ~0.17 miles per minute. (Note that this answer is only a rounded answer of her actual milage per minute)

Find the measure of the indicated angle to the nearest degree
A) 56°
C) 42°
B) 48°
D) 34°
The measure of the indicated angle to the nearest degree is D) 34°.
If one angle in a triangle is 90 degrees, then the sum of the other two angles must be 90 degrees as well since the angles in a triangle add up to 180 degrees.
A) 56°: This angle is already one of the known angles, not the remaining angle.
B) 48°: This angle cannot be the remaining angle since we already have a 56-degree angle, and the sum of the remaining two angles should be 180 - 90 - 56 = 34 degrees.
C) 42°: This angle cannot be the remaining angle since we already have a 56-degree angle, and the sum of the remaining two angles should be 180 - 90 - 56 = 34 degrees.
D) 34°: This angle can be the remaining angle. If one angle is 90 degrees and another angle is 56 degrees, then the remaining angle would be 180 - 90 - 56 = 34 degrees.
Therefore, the measure of the indicated angle to the nearest degree is D) 34°.

A fish tank is in the shape of a cuboid.
The length of the fish tank is 0.8 m and the width is 0.3 m.
The volume of water in the fish tank is 108 litres.
1m cubed=1000 litres.
Work out the depth of the water in the fish tank.
Answer:
Length = 0.8m
Breadth = 0.3m
Volume = 108litres = 108÷1000 = 0.108m³
Volume = l x b x h
0.108 = 0.8 x 0.3 x h
0.108 ÷ ( 0.8 x 0.3 ) = h
0.45 = h
The solution is 0.45 m
The height of the cubical fish tank is H = 0.45 m
What is the volume of a Cuboid?
A cuboid is defined as a three-dimensional shape, that has six rectangular faces, eight vertices and twelve edges
The volume of a cuboid is the product of its length , width and height
The volume of the cuboid is given by
Volume of Cuboid = Length x Width x Height
Given data ,
Let the height of the cubical fish tank be = H
The length of the cubical fish tank L = 0.8 m
The width of the cubical fish tank W = 0.3 m
The volume of water in fish tank V = 108 L
So , 108 L = 0.108 m³
The volume of the cubical fish tank V = 0.108 m³
Now ,
The Volume of Cuboid = Length x Width x Height
Substituting the values in the equation , we get
0.108 = 0.8 x 0.3 x H
H x 0.24 = 0.108
Dividing both sides of the equation by 0.24 , we get
H = 0.108 / 0.24
The value of H = 0.45
Therefore , the value of H = 0.45 m
Hence , the height of cubical fish tank is 0.45 m

Answer:
21.75 or [tex]21\frac{3}{4}[/tex]
Step-by-step explanation:
You have to convert from a mixed number to a decimal. You can follow the following steps: To do this:
1.) You must divide the fraction's numerator by the denominator.
2.) You must now add the quotient obtained to the part of the Whole number.
you will get:
[tex]{\large\boxed{\fcolorbox{7}{\frac{1}{4}=7+0.25=7.25 }}[/tex]
The scale of the image that maps "Figure a" to "Figure b" is:
[tex]{\large\boxed{\fcolorbox{1:7.25}}[/tex]
3.) You have to multiply by 7.25 the length of the corresponding side of "Figure A" in order to find the value "x."
The final result will be:
