The length of a rectangle is 25 cm.
What width will make the perimeter of the rectangle greater than 90 cm?
A. width <20 cm
B. width> 20 cm
OC. width ≥ 20 cm
OD. width 20 cm
E. width = 20 cm
Answer:
The correct answer is B, also may be Brain??
Step-by-step explanation:
The perimeter of a rectangle can be calculated using the formula P = 2l + 2w, where l is the length and w is the width. If the length of the rectangle is 25 cm and we want the perimeter to be greater than 90 cm, we can set up an inequality to solve for the width: 2l + 2w > 90.
Substituting the value for the length gives 2 * 25 + 2w > 90, which simplifies to 50 + 2w > 90. Subtracting 50 from both sides gives 2w > 40, and dividing by 2 gives w > 20.
So the width of the rectangle must be greater than 20 cm to make the perimeter greater than 90 cm. The correct answer is B: width > 20 cm.
Answer:
i'm guessing this but not 100% sure
Step-by-step explanation:
Let w = the width
P = 2l + 2w
2w + 2(25) > 90
2w + 50 > 90
2w > 40
w > 20 cm

If f(1) = 4 and f(n) = -4f(n-1) then find the value of ƒ (4).
Answer:
F(4) = -256
Step-by-step explanation:
f(1)=4
f(2)= -4* f(1) = -4 *4 = -16 F(2 ) = -16
f(3) = -4* f(2) = -4* (-16) = 64 F(3) = 64
f(4) = -4* f(3) = -4* 64 = -256 F(4) = -256
Answer:
f(4) = -256
Step-by-step explanation:
A recursive formula defines the nth term of a sequence based on the values of earlier terms.
To find the value of f(4) using the given recursive formula, we can work our way up from f(1) using the formula repeatedly.
Given recursive rule:
\(\begin{cases}f(1)=4\\f(n)=-4f(n-1)\end{cases}\)
To find f(2):
\(\begin{aligned}f(2)&=-4f(2-1)\\&=-4f(1)\\&=-4 \cdot 4\\&=-16\end{aligned}\)
To find f(3):
\(\begin{aligned}f(3)&=-4f(3-1)\\&=-4f(2)\\&=-4 \cdot -16\\&=64\end{aligned}\)
To find f(4):
\(\begin{aligned}f(4)&=-4f(4-1)\\&=-4f(3)\\&=-4 \cdot 64\\&=-256\end{aligned}\)
Therefore, the value of f(4) is -256.

Ox=-1, x=-2
Ox=1, x=3
Ox=-1, x=-3
Answer:
x= -1 and also x = -2
Which agrees with the second option in your list of answers
Step-by-step explanation:
We look for two numbers whose product is "2" (constant term in your quadratic equation) and which added give "3" (coefficient in the middle term with "x"). So we find the factors 1 and 2:
1 times 2 = 2 and 1 + 2 = 3
So we use these factor to expand the middle term and then factor by grouping:
\(x^2+3x+2=0\\x^2+x+2x+2=0\\x(x+1)+2(x+1)=0\\(x+1)(x+2)=0\)
Then for this product of binomials to give zero, each binomial must be zero. That is
x= -1 and also x = -2

The diameters of bolts produced in a machine shop are normally distributed with a mean of 5.18 millimeters and a standard deviation of 0.07 millimeters. Find the two diameters that separate the top 3% and the bottom 3%. These diameters could serve as limits used to identify which bolts should be rejected. Round your answer to the nearest hundredth, if necessary.
As per the concept of normal distribution, the two diameters of the bolt that has separate the top 3% and the bottom 3% are 5.2836 mm and 5.0764 mm respectively .
Normal distribution:
Normal distribution means the probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean and it has the bell shaped curve.
Given,
The diameters of bolts produced in a machine shop are normally distributed with a mean of 5.18 millimeters and a standard deviation of 0.07 millimeters.
Here we need to find the two diameters that separate the top 3% and the bottom 3% and these diameters could serve as limits used to identify which bolts should be rejected. we have also round off the result into nearest hundredth.
Here we have the given question with the values of,
The value of Mean is 5.18 millimeters
The value of Standard deviation is 0.07 millimeters.
Here we have to consider the following two cases, they are.
Case 1
We need to find x₁ such that that is P(X > x₁) = 3% when we convert it into decimal then we get P (X > x₁) = 0.03
So, as per the probability,
P (X ≤ x₁) = 1 - 0.03 = 0.97
So, z corresponding to the value of p = 0.97 is 1.48
Apply the given values to the formula of normal distribution then we get,
=> 1.48 = (x₁ - 5.18) /0.07
=> 0.1036 = x₁ - 5.18
Therefore, the value of x₁ is 5.2836
So, the diameter of the both with separate top 3% is 5.2836.
Case 2:
Next we have to take P(X < x₂) = 3% when we convert it into decimal then we get P (X < x₂) = 0.03
So, as per the given probability, the value of
P (X ≤ x₂) = 1 - 0.03 = 0.97
So, z corresponding to but here we have to use the negative because of the less than concept p = 0.97 is -1.48
Apply the values on the formula of normal distribution then we get,
-1.48 = (x₂ - 5.18) /0.07
Move the value to the other side
-0.1036 = x₂ - 5.18
When we simplify it,
x₂ = 5.0764
So, the diameter of the both with separate bottom 3% is 5.0764

We have 2 squares. One square is shaded 2/12 and the other shaded square in the diagram is 2/15 shaded. How much of the total diagram is shaded?
A.0.148
B.0.148 repeated
C. 0.3
D.0.3 repeated
Answer: The answer to your question is C. Brainliest?
Step-by-step explanation:
For the first square, we can multiply both the numerator and denominator by 5 to get an equivalent fraction with a denominator of 60:
2/12 = (2 x 5) / (12 x 5) = 10/60
For the second square, we can multiply both the numerator and denominator by 4 to get an equivalent fraction with a denominator of 60:
2/15 = (2 x 4) / (15 x 4) = 8/60
Now, we can add the two fractions:
10/60 + 8/60 = 18/60
Simplifying this fraction by dividing both numerator and denominator by 6, we get:
18/60 = 3/10
Therefore, the total shaded area in the diagram is 3/10 or 0.3 in decimal form.
The answer is C. 0.3.

Two families spent the same total amount of money during their vacation.
The first family stayed 5 nights at the hotel and spent $860 on food
The second family stayed 7 nights at the hotel and spent $650 on food.
Both families stayed at the same hotel with the same daily rate.
How much does each night cost at this hotel?
As a result, each night at the hotel costs $105 because both families spent the same amount of money on their vacation.
What is equation?In mathematics, an equation is a statement that indicates the equality of two mathematical expressions. An equation contains an equal sign (=) between two expressions, which means that the expressions on both sides of the equal sign have the same value. An equation can have one or more variables, which are typically represented by letters, such as x, y, or z. The values of these variables that satisfy the equation are called the solutions or roots of the equation. Equations are used in a wide range of mathematical fields, including algebra, calculus, geometry, and physics. They are used to model various real-world phenomena and to solve mathematical problems.
Here,
Let's assume that the cost of each night at the hotel is x dollars. Then, we can set up the following two equations based on the information given:
5x + 860 = Total cost for the first family
7x + 650 = Total cost for the second family
Since both families spent the same total amount of money during their vacation, we can equate the two total costs:
5x + 860 = 7x + 650
Simplifying this equation, we get:
2x = 210
Dividing both sides by 2, we get:
x = 105
Therefore, each night at the hotel costs $105 as 2 families spent the same total amount of money during their vacation.

Carrie has 3gallons of paint Bryan has 10quarts of paint how many more pints do Carrie have than Bryan
Carrie has 4 more pints of paint than Bryan.
Carrie has 3 gallons of paint, which is equivalent to 12 quarts (1 gallon = 4 quarts). On the other hand, Bryan has 10 quarts of paint.
To compare the quantities in the same unit, we note that 1 quart is equal to 2 pints.
Carrie's 12 quarts of paint is equivalent to 12 × 2 = 24 pints.
Bryan's 10 quarts is equivalent to 10 × 2 = 20 pints.
To find the difference, we subtract Bryan's pint quantity from Carrie's:
24 - 20 = 4 pints.
