You estimate that there are 60 marbles in a jar.The actual amount is 54 marbles. Find the percent error.Round to the nearest tenth of a percent if necessary
Answer:
the percent error is 10%
Step-by-step explanation:
Given that
The estimate value of the marbles is 60
And, the actual amount is 54 marbles
We need to find out the percent error
As we know that
Percent error = (Estimated - actual) ÷ (Estimated) × 100
= (60 - 54) ÷ 60 × 100
= 10%
Hence, the percent error is 10%
We simply applied the above formula

The area of a rectangle is found by using the formula A=l×w
, where A
is the area, l
is the length, and w
is the width. A rectangular desk top has an area of 18
square feet. The length of the desk is 6
feet. What is the width of the desk? Write and solve an equation.
Answer:
The width of the desk is 3

MARKING BRAINLIEST IF U HELP 19 - s = 13; s = -6 yes no question
Answer:
Step-by-step explanation:
We have the equation 19 - s = 13, and are asked to determine whether s = -6 fits in.
To solve, we need to isolate "s", do as followed and subtract 19 from both sides :
s = -6
Since this is equal to what the question is asking, yes s = -6 is correct.

24. The population of Bayside, CA increased from 23,560 in 1990. The annual rate of
population increase for the next 20 years was about 6%. Predict the population of Bayside in
2010.
Answer:
the population in 2010 is 75,656.33
Step-by-step explanation:
Given that
The increase in population in the year 1990 is 23,560
The Annual rate of interest is 6%
And, the time period is 20 years
We need to find out the population in 2010
So, the following formula should be used
= Population × (1 + rate)^time period
= 23,590 × (1 + 0.06)20
= 23,590 × 1.06^20
= 75,656.33
hence, the population in 2010 is 75,656.33
Which algebraic expression is a polynomial?
4x2 – 3x + StartFraction 2 Over x EndFraction
–6x3 + x2 – StartRoot 5 EndRoot
8x2 + StartRoot x EndRoot
–2x4 + StartRoot 3 Over 2 x EndRoot
Answer:
Option B.) –6x3 + x2 – √5
Step-by-step explanation:
A is wrong because, polynomial expressions cannot have a variable as a denominator.
C is wrong because there is no constant.
D is wrong because, polynomial expressions cannot have a variable as a denominator.
Hope that helps! :-)
The algebraic expressions which is a polynomial is; Choice B: –6x3 + x2 –√5
What is a polynomial?An algebraic expression, put simply is an expression made up of integer constants, variables, and the algebraic operators. For example, 5x² − 7xz + c is an algebraic expression.
A polynomial is all of the above and in addition, non-negative integer exponentiation of variables
Only choice B; satisfies this condition as to term in the expression is divided by a variable.

Convert the angle 17pi/12 radians to degrees.
Answer: 255°
Step-by-step explanation:
To convert an angle in radians to degree, we've to multiply it by 180/π. In this case, converting the angle 17pi/12 radians to degrees will be:
= 17π/12 × 180/π
= 17 × 15°
= 255°
The answer is 255°.

The area of the base of this cylinder is 25picm^2 and the height of the cylinder is 8cm. Find the surface area of the cylinder.
Answer:
408.2cm
Step-by-step explanation:
Given data
Area of base= 25πcm^2
Height= 8cm
Let us find the radius of the cylinder
Area= πr^2
25π= πr^2
25= r^2
r= √25
r= 5cm
Let us now find the surface area
SA=2πrh+2πr^2
Substitute
SA= 2*3.14*5*8+ 2*3.14*5^2
SA= 251.2+ 157
SA= 408.2cm
Hence the surface area is 408.2cm
