A reference book with 250 pages has 1 page without pictures.
What percent of the pages do not have pictures?
O 0.1%
O 0.4%
O 0.5%
0 1.1%
Answer:
0.4 %
Step-by-step explanation:
Given:
total number of pages = 250number of pages without pictures = 1Percent of pages that do not have pictures = (number of pages without pictures ÷ total number of pages) × 100%
= 1/250 × 100%
= 0.004 × 100%
= 0.4 %
Answer:
0.4%
explanation:
without pages: 1total page: 250solve:
[tex]\sf \dfrac{1}{250} * 100[/tex]

A curve has equation y = x
3 − 4x
2 + 2x
Find the x coordinate of each of the points on the curve at which the gradient of the tangent to the
curve is 2
Answer:
The derivative (or gradient function) describes the gradient of a curve at any point on the curve. Similarly, it also describes the gradient of a tangent to a curve at any point on the curve.
To determine the equation of a tangent to a curve:
Find the derivative using the rules of differentiation.
Substitute the \(x\)-coordinate of the given point into the derivative to calculate the gradient of the tangent.
Substitute the gradient of the tangent and the coordinates of the given point into an appropriate form of the straight line equation.
Make \(y\) the subject of the formula.
The normal to a curve is the line perpendicular to the tangent to the curve at a given point
Step-by-step explanation:
Translate the triangle.
Then enter the new coordinates.
answer:
A' (-3,3) B' (-2,-1) C' (-6, -2)

Which expression shows 5 + 5 + 5 + 5 as multiplication?
5 × 2
5 × 4
5 × 5
5 × 10
Answer:
5 × 2= 10
5 × 4=20
5 × 5=25
5 × 10=50
5+5+5+5=20
there your answer
Step-by-step explanation:
you slow -_-
Answer : 5 x 4 (Option C)
Step-by-step explanation : 5 + 5 + 5 + 5 = 20
By trial & error method, we get
5 x 2 = 10 ≠ 20
5 x 4 = 20
5 x 5 = 25 ≠ 20
5 x 10 = 50 ≠ 20
Hence 5 x 4 is the right answer
You can either follow the trial & error method or the following method !!
5 + 5 + 5 + 5 has ' 4 ' fives
Hence, 5 + 5 + 5 + 5 = 5 (since it is the no) x 4 (since it is the no of times 5 is repeating)
Hence 5 x 4 is the right answer

what is the approximate height of the rice container if the radius is 2.5 in. and the volume is 235.5 in cubed
Answer:
12 in
Step-by-step explanation:
r = 2.5 in
V = 235.5 in³
Find h
Use V = πr²h
so 235.5 = 3.14 * 2.5² * h
235.5 = 19.625 h
h = 235.5/19.625 = 12 in

Answer:
1,-4.5
Step-by-step explanation:
Answer:
(-2,-9) is the answer
3x - 2y = 12
3(-2) - 2(-9) = 12
-6+18 = 12
12 = 12
-2b+2(b-10)=2(10+5b)
Answer:
b= -4
Step-by-step explanation:
On both sides of the equation has distributive property. We need to solve that first. Let's start with the left side of the equation.
*Positive multiplied by a negative equals a negative
-2b+2(b-10)= 2(10+5b)
-2b+2b-20= 2(10+5b)
-20= 2(10+5b)
Now let's solve the right side of the equation
-20= 20+10b
-20 -20
-40 = 10b
-40/10 = 10b/10
b= -4

the difference of a number and ten is at least 91
Answer:
x-10 [tex]\geq[/tex] 91
Step-by-step explanation:
Difference means subtraction, and "a number" since not specified is x, and at least means greater than or equal to and not less than. So the difference (subtract) of a number (x) and 10 is at least (greater than or equal to) 91 :D
What is (x+4)(3x+7)/(x+4)(x+2) simplified?
Answer:
[tex]\frac{3x+7}{x+2}[/tex]
Step-by-step explanation:
Given the following question:
[tex]\frac{(x+4)(3x+7)}{(x+4)(x+2) }[/tex]
In order to simplify the expression given we can only cancel the common factor which is four.
[tex]\frac{(x+4)(3x+7)}{(x+4)(x+2) }[/tex]
[tex]cf=(x+4)[/tex]
[tex]\frac{x+4}{x+4}[/tex]
[tex]=\frac{3x+7}{x+2}[/tex]
Cannot be simplified further due to it not having any more common factors. Your answer is "3x + 7 / x + 2."
Hope this helps.
Answer:
( 3x+7 ) / ( x+2 )
Step-by-step explanation:
\frac{(x+4)(3x+7)}{(x+4)(x+2)}
When you set up the equation like a fraction, you can now cancel out like terms. (x+4) is in the denominator- as well as the numerator. They are the same in parentheses. So you can cancel. Once that's done, you'll be left with
\frac{3x+7}{x+2}
You cant simplify any further because there are no more (like groups) aka (common factors)
( 3x+7 ) / ( x+2 )

A square has a perimeter of 12x + 40 units. Which expression represents
the side length of the square in units? *
X + 4
O x + 40
O 3x + 10
3x + 43
Answer:
3x+10
Step-by-step explanation:
Since the perimeter of a square is 4 times the side length, to find the side length given the perimeter, just divide by 4:
(12x+40)/4 = 3x+10
Therefore, the answer is 3x+10

The area of a rectangle is 75 square feet, and the length is 25 feet. What is the perimeter?
Answer:
56 feet
Step-by-step explanation:
75/25=3 feet
this is another side.
(3+25)x2+56 feets
Answer:
75ft.
Step-by-step explanation:
What you do is subtract two 25s from the area (because there are two sides for length) which gives you 25. The width would be half of that which is 12.5. Then add two widths (12.5+12.5=25), and add that to two lengths (25+25=50). The answer is 75ft as well. Please tell me if I'm wrong.

suppose the probability you will get an A in this class is .25 and the probability you will get a B is .50. What is the probability your grade will be above a C?
Answer:
75% chance
Step-by-step explanation:
Probability always adds to 1.00
Letter grades are always in the form A, B, C, D...
The grades above a C are A, which is a 25% chance and B, which has a 50% chance. Adding these up we get a 75% chance.
#LearnWithBrainly
The probability of getting a grade above a C is 0.75, or 75%.
We have,
To calculate the probability of getting a grade above a C, you need to add the probabilities of getting an A or a B.
Given:
Probability of getting an A (P(A)) = 0.25
Probability of getting a B (P(B)) = 0.50
A grade above a C includes grades of A and B.
Therefore, the probability of getting a grade above a C (P(above C)) is:
P(above C) = P(A) + P(B)
P(above C) = 0.25 + 0.50
P(above C) = 0.75
Thus,
The probability of getting a grade above a C is 0.75, or 75%.
