Answer:
1. 5.6%
2. 15%
3. 300 seats
4. 2.3%
Step-by-step explanation:
1. Percent error is A-E/E*100
A is actual and e is expected
376-356/356= 0.05618*100= 5.6%
2. 17-20/20=-0.15*100= 15%
3. This time we have to solve for the actual
x-250/250*100=20
x=300 seats
4. 342-350/350=-0.0228571429*100= 2.3%

Answer:
4 ft = height
10 ft = base
Step-by-step explanation:
The area of a triangle is given by ...
A = 1/2bh
Filling in the given value, we get the relation ...
20 = 1/2bh
40 = bh
We know the factors of 40 are ...
40 = 1×40 = 2×20 = 4×10 = 5×8
Of the numbers that area available, only the pair 4×10 will give the desired result.
The height is 4 ft; the base is 10 ft.

If you change the sign of a point's x-coordinate, how does the location of the point change? CLEAR CHECK The point moves down and to the left. The point crosses over the x-axis. The point crosses over the y-axis. Not enough information is provided.
Answer:
The point crosses over the y-axis
Step-by-step explanation:
Given
A change in the sign of x coordinate
Required
The effect on the point location
Assume the coordinate to be (x,y).
The above point is located in the first quadrant,
When the x value changes to negative i.e. (-x,y)
The point moves from the first quadrant to the second quadrant
This implies that, the point crosses over the y-axis.
Similarly, assume the coordinate to be (-x,-y).
The above point is located in the third quadrant,
When the x value changes i.e. (x,-y)
The point moves from the first quadrant to the fourth quadrant
This implies that, the point crosses over the y-axis.
Here are the prices (in thousands) for 10 houses for sale in a local neighborhood: 285,288,289,290,299,300,308,309,312,314 . Which measure should be used to summarize the data
Answer:
Mean and Median
Step-by-step explanation:
Given the data :
285,288,289,290,299,300,308,309,312,314
To summarize the data using a measure of centre, considering that the dataset doesn't show a great deal of variation we could use either the mean or median value.
The mean, x = Σx / n
n = sample size = 10
Σx = 2994 ; n = 10
x = 2994 / 10 = 299.4
Also the median value ;
1/2 * (n + 1)th term
1/2 * (10 + 1)th term
1/2 * 11
= 5.5 th term
= (5 + 6)th / 2
= (299 + 300) / 2
= 299.5
A triangle has two sides of length 20 and 11. What is the largest possible whole-number length for the third side?
Answer:
30
Step-by-step explanation:
20+11=31
It can't be exactly 31 but it can be any number less than 31, so the nearest whole number down is 30
If a tennis ball has a diameter of 14.6, and is cut in half. What is the volume of the half of the tennis ball? Use 3.14 for pi.

4. Marcy plans to save $3 in January, 54 in February, S6 in March, and $9 in April. If she continues this pattern, how much money will she save in December?
Please help and write a proper answer I really need it. Thanks.
Answer:The value of the surface area (in square centimeters) of the cone is equal to the value of the volume (in cubic centimeters) of the cone. The formula for the surface area S of a cone is S=πr2+πrl, where r is the radius of the base and l is the slant height.
Step-by-step explanation:
Answer:
A cone is 360 triangles rotated in a circle, so find the hypotenuse of the triangle and multiplying it by 360 you would get the surface area of the cone

Answer:
3(4+√2)
Step-by-step explanation:
Here we need to find the perimeter of the given figure. Here the given figure is made from a triangle and a square. The side lenght of the square is 3. We need to find the hypontenuse of the triangle in order to find Perimeter .
• Using Pythagoras Theorem :-
⇒ h² = p² + b²
⇒ h² = 3² + 3²
⇒ h² = 9 + 9
⇒ h² = 18
⇒ h = √[ 9 × 2 ]
⇒ h = 3√2 .
Therefore the perimeter will be ,
⇒ P = 3√2 + 3 + 3 + 3 + 3
⇒ P = 3√2 + 12
⇒ P = 3( 4 + √2)
Hence the perimeter of the figure is 3(4+√2) .which number line best represents the solution to the inequality 3.3w - 9 > -22.27
Plz answer hurry
Answer:
Step-by-step explanation:
The answer would be (G)
The value of w is greater than -4 which will best represent the inequality 3.3w - 9 > -22.27 on number line.
What is a number line?Number lines are simple, visual pictures of how the values of numbers increase and decrease.
Given an inequality 3.3w - 9 > -22.27
On solving, we get,
3.3w - 9 > -22.27
3.3w > -22.27 + 9
3.3w > -13.27
w > -4
Hence, the value of w is greater than -4 which will best represent the inequality 3.3w - 9 > -22.27 on number line.

Answer:
#12.) 3m+2=17
3(5)+2=17
5*3=15
15+2=17
Step-by-step explanation:
Answer:
3 x 2 + 5 - 4 = 7 if its not 7 then try 15 most likely 7
m = 5 its already given on the top or its 17
7 x 5 - 2 > 12, m = 5 or the answer is 33 for the left side
for this you need to draw an empty circle on two and make the line bold starting from 2 to the 10.
