Answers
Answer:
x= 20
Step-by-step explanation:
The three angles add to 90 degrees
x+2x+x+10 = 90
Combine like terms
4x+10 = 90
Subtract 10 from each side
4x +10-10 = 90-10
4x = 80
Divide by 4
4x/4 = 80/4
x = 20
Answer:
x = 20
Step-by-step explanation:
The three angles are complementary to each other.
That means they add up to 90 degrees.
x + 2x + (x + 10) = 90
Combine like terms.
4x + 10 = 90
Subtract 10 on both sides.
4x = 80
Divide both sides by 4.

A bowling ball is pushed with a force of 22.0 N and accelerates at 5.5 m/s2. What is the mass of the bowling ball? Ik the answer is 4.0, but I got it wrong for 4.00. I based the significant numbers off the 22.0 but apparently it's the 5.5. I always get it wrong when the question involves two numbers with different amounts of significant numbers (sometimes I use the smaller one but it wanted the bigger). How do I know when to use more or less significant numbers?
Answers
Step-by-step explanation:
You should always use the least number of significant figures. The exception is exact numbers or constants.
For example, there are 60 minutes in an hour. Even though this number has one significant figure, it is an exact number. So 15 minutes converted to hours would be 0.25 hr.

If you're good at bearings pls help mee
What is the true bearing of Milton from Binji?
Answers
The leading 0 is important with true bearings. Any true bearing must be three digits.
======================================================
Explanation:
It's not stated, but I'm assuming that Binji and Congo form a flat horizontal line.
B = Binji's location
M = Milton's location
C = Congo's location
The given angles are M = 76 and C = 38. The missing angle is
B = 180-M-C
B = 180-76-38
B = 66
Subtract this from 90 to get 90-66 = 24
The true bearing of Milton from Binji is 024 degrees
In other words, if you are at Binji's location, face directly north, and turn 24 degrees clockwise (turn to the right), then you'll be facing Milton's location.
-------------
Extra info:
In terms of compass notation, the true bearing of 024 degrees converts to N 24 E. This is the same as E 66 N, though convention usually has north used more often (since it's a common reference point with compasses).
N 24 E = start facing north, turn 24 degrees to the east
E 66 N = start facing east, turn 66 degrees to the north
Using everyday knowledge, indicate whether the if-then statements are correct forward-only or both forward and reverse.

Statement 2: If the sprinklers are on, then the grass is wet.
Answers
Answer:
1. Both forward and backward
2. Only forward
Step-by-step explanation:
The reason Statement 1 can be both forward and reverse is because is Bo and Mel are related then it will word forward and backward.
The reason Statement 2 can be only forward is because is the sprinklers are on then the grass is wet will work since it is saying ONLY the sprinklers are on. If it is reverse and the grass is wet if the sprinklers are ONLY on than that is false since if it rains than the grass can also be wet. So there are multiple ways that the grass can be wet hence the answers.

write a system of equations for the problem, and then solve the system. if a plane can travel 340 miles per hour with the wind only 260 miles per hour against the wind, find the speed of the wind and the speed of the plane in still air. please show step by step
Answers
Answer:
The speed of plane = 40 m/s
The speed of the wind = 300 m/s
Step-by-step explanation:
Let the speed of the plane = Y
And the speed of the wind = X
If the plane then travel 340 miles per hour with the wind, that means the plane and the wind are moving in the same direction. Therefore,
X + Y = 340 ..... ( 1 )
Also, 260 miles per hour against the wind. That is, the plane is moving opposite to the direction of the wind. Therefore,
X - Y = 260 ..... ( 2 )
Solve the two equations simultaneously by addition. That will eliminate Y
X + Y = 340
X - Y = 260
2X = 600
X = 600/2
X = 300 m/s
Substitutes X in equation (1)
300 + Y = 340
Make Y the subject of formula by collecting the like terms
Y = 340 - 300
Y = 40 m/s
Therefore, the speed of the plane is 40 m/s. While the speed of the wind is 300 m/s.
Mr. Wilson invested money in two accounts his total investment was $8000. If one account pays 6% and interest and the other pays 12% interest how much did he invest in each account if he earned a total of $600 in an interest in one year
Answers
Answer:
Mr. Wilson invested $ 2,000 in the 12% simple interest account and $ 6,000 in the 6% simple interest account.
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Amount of the investment = $ 8,000
Interest rate of the first account= 6% simple
Interest rate of the second account= 12% simple
Interest of the accounts in a year = $ 600
2. How much did he invest in each account?
For answering the question, we will use the following equation:
x = Amount invested in the first account
8,000 - x = Amount invested in the second account
0.06x + 0.12 * (8,000 - x) = 600
0.06x + 960 - 0.12x = 600
-0.06x = 600 - 960 (Subtracting 960 at both sides)
-0.06x = -360
x = -360/-0.06
x = 6,000 ⇒ 8,000 - x = 2,000
Mr. Wilson invested $ 2,000 in the 12% simple interest account and $ 6,000 in the 6% simple interest account.
In a newspaper, it was reported that the number of yearly robberies in Springfield in 2013 was 100, and then went up by 25% in 2014. How many robberies were there in Springfield in 2014?
Answers
Answer:
125
Step-by-step explanation:
So saying something went up by 25% means that it is essentially
X + .25X
So in this case X = 100 and .25X = 25
So 100 + 25 = 125
A 5cm x 11cm rectangle sits inside a circle with radius of 12 cm. What is the area of the shaded region? Round your final answer to the nearest hundredth.
Answers
Answer:
Step-by-step explanation:
area of shaded region = 3168/7 - 55 = 397.5cm^2 (app)= 0.397cm^2 ( since we have to round to nearest hundredth
Answer:
The answer is
397.40 cm²Step-by-step explanation:
To find the area of the shaded area first find the area of both the rectangle and the circle and subtract the smaller one from the larger one.
that's
For the rectangle
Area of rectangle = length × width
From the question
length = 5cm
width = 11 cm
So we have
Area of rectangle = 5cm × 11cm = 55cm²
For the circle
Area of a circle = πr²
where r is the radius
From the question
r = 12 cm
Area of circle = π (12)²
= 144π
= 452.40 cm²
Area of shaded figure
Since the area of the rectangle is smaller than that of the circle we subtract the area of the rectangle from the circle
That's
452.40 cm² - 55cm²
= 397.40 cm² to the nearest hundredth

The answer is option D.
Their angles measures cannot be equal.
Answer:
D
Step-by-step explanation:
Hello,
What the question requires of us is just the property of complimentary angles and which is
The sum of their angles must be equal to 90°.
When two angles combine together to form angle 90°, it is said to be complimentary and they're referred to as a right angled triangle.
From the option, none of the angles can be up to a right angle triangle (90°)
The sum of their angles can be an acute triangle I.e 45°
45° + 45° = 90°
Knowing the fact that the angles can both be an acute angle (45°), it would be wrong to say both angles cannot be equal.

A little shop sells Christmas toys. The wholesale price for each toy in a consignment of 50 toys was $5.5. Half of this quantity was sold before Christmas for the sales price of $15 per piece. two-fifth of the remaining toys have been sold in the next six days for half of the sales price. Finally, the rest of toys have been sold after the New Year for one-third of the sales price. What was the profit the shop made on selling these toys?
Answers
Answer:
[tex]Profit = \$250[/tex]
Step-by-step explanation:
Given
Number of Toys = 50
Unit Cost Price = $5.5
Unit Selling price = $15
Required
Determine the profit after sales
First, we need to determine the total cost price;
[tex]Cost\ Price = Number\ of\ toy *\ Unit\ cost\ price[/tex]
[tex]Cost\ Price = 50 * \$5.5[/tex]
[tex]Cost\ Price = \$275[/tex]
First, we need to determine the total sales;
____________________________________________________
Half of the toy was sold at $15;
[tex]Half\ of\ the\ toy = \frac{1}{2} * 50[/tex]
[tex]Half\ of\ the\ toy = 25[/tex]
[tex]Sales = \$15 * 25[/tex]
[tex]Sales = \$375[/tex]
____________________________________________________
Two-fifth of the remaining was sold at half of the sales price
From the above calculation;
[tex]Remaining\ Toy = 50 - 25[/tex]
[tex]Remaining\ Toy = 25[/tex]
Calculating Two-fifth of the remaining:
[tex]\frac{2}{5} * 25[/tex]
[tex]= \frac{50}{5}[/tex]
[tex]= 10[/tex]
Calculating half of the sales price:
[tex]\frac{1}{2} * \$15[/tex]
[tex]\$7.5[/tex]
This means that 10 toys were sold for $7.5
[tex]Sales = 10 * \$7.5[/tex]
[tex]Sales = \$75[/tex]
____________________________________________________
The remaining was sold at one-third of the sales price
From the above calculations (1 & 2);
[tex]Remaining\ Toy = 50 - 25 - 10[/tex]
[tex]Remaining\ Toy = 15[/tex]
Calculating one-third of the sales price:
[tex]\frac{1}{3} * \$15[/tex]
[tex]\$5[/tex]
This means that 15 toys were sold for $5
[tex]Sales = 15 * \$5[/tex]
[tex]Sales = \$75[/tex]
____________________________________________________
Now the total sales can be calculated;
[tex]Total\ Sales = \$375 + \$75 + \$75[/tex]
[tex]Total\ Sales = \$525[/tex]
[tex]Profit = Total\ Sales -\ Cost\ Price[/tex]
[tex]Profit = \$525 -\$275[/tex]
[tex]Profit = \$250[/tex]

Can someone please help me
Answers
Answer:
C. 8(1)=8(−4+3/8x)
Step-by-step explanation:
Given equation
1=−4+3/8x
in this equation in denominator we have 8x,
since we are solving for x we cannot eliminate it, but we have to eliminate 8 in denominator, so that there only numerator in equation and solving process becomes easier.
To eliminate 8,we need to multiply both side by 8, so as to balance the equation and also 8 from denominator gets cancelled in RHS.
1=−4+3/8x
multiply both side by 8
8(1)=8(−4+3/8x)
Thus, option c is correct one
8(1)=8(−4+3/8x)
solving it
8 = -32 + 3/x
adding both side 32
8+32 = -32 + 3/x -32
=> 40 = 3/x
=> x = 3/40
