Step-by-step explanation:
there are 2.54 centimeters in 1 inch. there are 100 centimeters in 1 meter. to the nearest inch, how many inches are in 7 meters
There are approximately 275.59 inches in 7 meters.
To find out how many inches are in 7 meters, we will first convert meters to centimeters, and then centimeters to inches.
Since there are 100 centimeters in one meter, we can calculate:
7 meters × 100 centimeters/meter = 700 centimeters
Now, we know there are 2.54 centimeters in one inch, we can convert the 700 centimeters to inches:
700 centimeters × 1 inch/2.54 centimeters ≈ 275.59 inches
To the nearest inch, there are approximately 275.59 inches in 7 meters.

The graph of the function y = x2 + 2 is shown. Which equation will shift the graph of the function down 4 units?
A) y = x2 + 6
B) y = x2 - 2
C) y = (x + 4)2 + 2
D) y = (x - 4)2 + 2
Answer: OPTION B.
Step-by-step explanation:
Below are shown some transformations for a function f(x):
1) If [tex]f(x)+k[/tex], the function is shifted up "k" units.
2) If [tex]f(x)-k[/tex], the function is shifted down "k" units.
In this case you have the following function, which you can call f(x):
[tex]y =f(x)= x^2 + 2[/tex]
Based on the transformations explained before, if this function is shifted down 4 units, you know that function obtained g(x) is:
[tex]g(x)= x^2 + 2-4\\\\g(x)= x^2 -2[/tex]
Therefore, the equation that will shift the graph of the function down 4 units, is:
[tex]y= x^2 -2[/tex]
A sporting goods stores sells footballs, basketballs, and volleyballs. A football costs $35, a basketball costs
s , and a volleyball costs $15. On a given day, the store sold 5 times as many footballs as volleyballs. They
brought in a total of $3750 that day, and the money made from basketballs alone was 4 times the money
made from volleyballs alone. How many footballs, basketballs, and volleyballs were sold? Just set up the
problem
Answer:
The number of footballs, basketballs and volleyballs were sold are 75, 36 and 15 respectively.
Step-by-step explanation:
Consider the provided information.
A football costs $35, a basketball costs $25 and a volleyball costs $15.
Let F represents the football, B represents the basketball and V represents the volleyball.
On a given day, the store sold 5 times as many footballs as volleyballs.
[tex]F=5V[/tex]......(1)
They brought in a total of $3750 that day,
[tex]35F+25B+15V=3750[/tex]......(2)
The money made from basketballs alone was 4 times the money.
[tex]25B=4(15V)[/tex]......(3)
By equation 1, 2 and 3.
[tex]35(5V)+4(15V)+15V=3750[/tex]
[tex]250V=3750[/tex]
[tex]V=15[/tex]
Substitute the value of V in equation 1 and 3.
[tex]F=5(15)=75[/tex]
[tex]25B=4(15\times 15)\\B=36[/tex]
Hence, the number of footballs, basketballs and volleyballs were sold are 75, 36 and 15 respectively.
The system of equations is as follows:
35F + 25B + 15V = 3750
1 F = 5V
25B = 60V
Let's define the variables first:
F: Number of footballs soldB: Number of basketballs soldV: Number of volleyballs soldWe are given the following information:
A football sells for $35, then the money made from footballs is 35F.A basketball sells for $25, then the money made from basketballs is 25B.A volleyball sells for $15, then the money made from volleyballs is 15V.The store sold 5 times as many footballs as volleyballs: F = 5VThe total sales amounted to $3750: 35F + 25B + 15V = 3750The money made from basketballs was four times the money made from volleyballs: 25B = 4 × 15VWe can write the system of equations as:
35F + 25B + 15V = 3750
F = 5V
25B = 60V
Complete question:

a box 12 cm long, 5 cm wide and 12 cm height. A cardboard rectangle is inserted along the diagonal to divide the box vertically into two equal spaces. Determine the dimensions f the cardboard rectangle.
Answer:
The Cardboard dimensions are 13cm in length and 12cm in breadth
Step-by-step explanation:
We can use Pythagoras Theorem to find the length the Cardboard (a²+b²=c²). Let A be 5 and B be 12, we find that C is equivalent to 13. The height is 12, thus the breadth of the Cardboard is also 12. Hope this helps :)
Final answer:
The dimensions of the cardboard rectangle are 5 cm by 12√2 cm.
Explanation:
To determine the dimensions of the cardboard rectangle inserted diagonally into a box with given dimensions, we first need to calculate the diagonal of the box that lies in the length-height plane. The box is 12 cm long and 12 cm high.
By using the Pythagorean theorem, we can find the length of the diagonal 'd' using the formula √(l² + h²), where 'l' is the length of the box and 'h' is the height.
In this case, 'd' = √(12² + 12²) = √(144 + 144) = √(288) = 12√2 cm.
Thus, the dimensions of the cardboard rectangle are its width, which is 5 cm (the width of the box), and its diagonal, which is 12√2 cm.

What is the remainder when x4 - 5x3 + 3x2 - 2x +7 is divided by x - 1?
Answer:The remainder can be calculated by doing the following steps;
Step-by-step explanation:
The remainder when f(x) = x⁴ - 5x³ + 3x² - 2x +7 is divided by x - 1 is 4.
Polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables.
The remainder theorem states that when a polynomial, f(x), is divided by a linear polynomial , x - a, the remainder of that division will be equivalent to f(a).
Given that f(x) = x⁴ - 5x³ + 3x² - 2x +7 is divided by x - 1
x - 1 = 0
x = 1
f(1) = 1⁴ - 5(1)³ + 3(1)² - 2(1) + 7 = 4
The remainder when f(x) = x⁴ - 5x³ + 3x² - 2x +7 is divided by x - 1 is 4.

6 out of 9
Answer: 2/3
Step-by-step explanation: We can rewrite the ratio 6 out of 9 as the fraction 6/9 by putting 6 in the position of the numerator and 9 in the position of the denominator.
Notice however, 6/9 is not in lowest terms so we need to divide the numerator and the denominator by the greatest common factor of 6 and 9 which is 3 to get the equivalent fraction 2/3.
Therefore, the ratio 6 out of 9 can be rewritten as the fraction 2/3.

Apple produce pays it's employees by the formula P(b)=7/2b+35, where P(b) is the employee's total daily pay and b is the number of bushels of apples picked . According to the formula,what is the rate employees are paid per bushels of apples picked?
Answer:
Apple Produce pays employees 38.5 for per bushels of apples picked.
Step-by-step explanation:
Given:
Apple produce pays it's employees by the formula;
[tex]P(b) = \frac{7}{2}b+35[/tex]
[tex]P(b)[/tex] ⇒ Employee's Total daily pay
[tex]b[/tex] ⇒ Number of bushels of apples
We need to find the Rate employees are paid per bushels of apples picked.
Rate employees are paid per bushels of apples picked can be calculated by substituting the value of "b = 1" in above formula.
Substituting the value of b = 1 in above formula we get;
[tex]P(1) = \frac{7}{2} \times 1+35\\[/tex]
Now We will take LCM to make the Denominator common.
[tex]P(1) = \frac{7}{2} +\frac{35\times 2}{2} = \frac{7}{2} +\frac{70}{2} = \frac{77}{2}= 38.5[/tex]
Hence Apple Produce pays employees 38.5 for per bushels of apples picked.

santa has nine reindeer that pull his sleigh on christmas eve what is the ratio of legs ears as it relates to santad reindeer?
Final answer:
The ratio of legs to ears for Santa's reindeer is 2 legs/ear.
Explanation:
The question is asking for the ratio of legs to ears as it relates to Santa's reindeer. We know that Santa has 9 reindeer and reindeer typically have 4 legs and 2 ears. So the total number of legs would be 9 reindeer * 4 legs/reindeer = 36 legs. And the total number of ears would be 9 reindeer * 2 ears/reindeer = 18 ears. To find the ratio of legs to ears, we divide the number of legs by the number of ears: 36 legs / 18 ears = 2 legs/ear.
