Kenny wants to place a picture frame in the center of a wall that is 17 3/4 feet wide. The picture is 2 3/4 feet wide. How many feet from each side of the wall must the frame be so that it is centered?
Answer:
The distance of frame from each side of the wall so that it is at centered is 7.5 feet
Step-by-step explanation:
Given as :
The measure of the wall = 17[tex]\dfrac{3}{4}[/tex] feet
i.e The measure of the wall =[tex]\dfrac{71}{4}[/tex] feet
The measure of the picture = 2[tex]\dfrac{3}{4}[/tex] feet
i.e The measure of the picture =[tex]\dfrac{11}{4}[/tex] feet
Let The distance from each side of wall so that frame at centered = x feet
Now, According to question
x = The measure of the wall - measure of the picture
Or, x = [tex]\dfrac{71}{4}[/tex] feet - [tex]\dfrac{11}{4}[/tex] feet
Or, x = [tex]\dfrac{71 - 11}{4}[/tex] feet
Or, x = [tex]\dfrac{60}{4}[/tex] feet
∴ x = 15 feet
Now, For each side so that frame st centered = [tex]\dfrac{15}{2}[/tex] feet
Or, For each side so that frame st centered = 7.5 feet
Hence,The distance of frame from each side of the wall so that it is at centered is 7.5 feet Answer
List ways to show 46 as tens and ones
Answer:
4 tens 6 ones
Step-by-step explanation:
those are the only way
The number 46 can be expressed as 4 tens and 6 ones, representing the value 40 plus 6, utilizing the powers of ten place value system.
Explanation:When expressing the number 46 in terms of tens and ones, we use the place value system which is based on powers of ten.
In this system, each place in the number represents a power of 10.
To represent 46 as tens and ones, we look for the highest power of ten that fits into the number without exceeding it.
In the case of 46, that value is 40, because 4 tens (4 x 10) equal 40, and there are 6 ones left over.
Therefore, we can say that 46 consists of 4 tens and 6 ones. This can be shown visually as:
A charity organization is having a fundraiser.
PPP represents the fundraiser's profit (in dollars) if nnn tickets are sold. A negative profit means the expenses exceeded the income from tickets.
P=70n-1500P=70n−1500
Answer:
Hence, the price of single ticket is $70.
Step-by-step explanation:
Consider the provided equation.
[tex]P(n) = 70n - 1500[/tex]
As we know that: Profit = Income – Cost
Here, P(n) represents the fundraiser's profit (in dollars) and n represents the number of tickets sold and cost is 1500
Since, n is multiplied by 70 that represents the price of per ticket is $70.
Hence, the price of single ticket is $70.
The expenses of the fundraiser are $40.
Step 1:
To find the expenses of the fundraiser, we can use the given equation:
[tex]\[ P = 70n - 1500 \][/tex]
Here, P represents the profit and n represents the number of tickets sold.
Step 2:
Since profit is the difference between income and expenses, and a negative profit means expenses exceeded income, we can set the profit P to zero and solve for the number of tickets n. Then, we can use the value of n to find the expenses.
When [tex]\( P = 0 \)[/tex]:
[tex]\[ 0 = 70n - 1500 \][/tex]
Solving for n:
[tex]\[ 70n = 1500 \][/tex]
[tex]\[ n = \frac{1500}{70} \][/tex]
[tex]\[ n \approx 21.43 \][/tex]
Since you can't sell a fraction of a ticket, we take the next whole number, which is 22.
Step 3:
Now, we can find the expenses using the value of [tex]\( n \)[/tex]:
[tex]\[ P = 70 \times 22 - 1500 \][/tex]
[tex]\[ P = 1540 - 1500 \][/tex]
[tex]\[ P = 40 \][/tex]
Therefore, the expenses of the fundraiser are $40.
Complete Correct Question:
A charity organisation is having a fundraiser. P represents the fundraiser's profit in dollars if 7 tickets are sold. A negative profit means the expenses exceeded the income from tickets. P=70n-1500 What are the expenses of the fundraiser?

Answer:
grapes cost $1.25 per pound
blueberries cost $4 per pound
Step-by-step explanation:
We have two unknowns, the cost of grapes and the cost of blueberries.
I'll call grape g and blueberries b.
since 21lb grapes and 44lb of blueberry cost $202.25, we can set up our first equation.
21g + 44b = 202.25
and the question also said 30lb grape and 22lb blueberries cost $125.50, we can set up our second equation.
30g + 22b = 125.5
now that we have two equations, you can use any methods you want to solve for the variable. I'm gonna use elimination.
21g + 44b = 202.25
-2(30g + 22b = 125.50)
━━━━━━━━━━
-39g = -48.75
g = 48.75/39
g = 1.25, grapes cost $1.25 per pound
now use substitution to find the cost of blueberries. you know the value of g now so plug it back in to one of the equation.
21g + 44b = 202.25
21(1.25) + 44b = 202.25
26.25 + 44b = 202.25
44b = 176
b = 4 , blueberries cost $4 per pound

please what is the derivative of y=cos(^7)base x
The derivative of y=cos(^7)base x is
Dydx = (cos(7x))x⋅(ln(cos(7x))−7x(tan(7x)))
Step-by-step explanation:
step 1 :
y= (cos(7x))x
Take the natural logarithm of either side, bringing the t x down to be the coefficient of the right hand side we get the answer:
step 2 :
⇒ln y = xln (cos (7x))
Differentiate each side with respect to x. The rule of implicit differentiation: ddx (f(y)) = f'(y) ⋅ dydx
step 3 :
∴1y ⋅ dydx = ddx (x) ⋅ln (cos(7x)) + ddx (ln (cos(7x)))⋅x
Use the chain rule for natural logarithm functions – ddx ( ln (f(x)) )= f'(x)f(x) - we can differentiate the ln (cos (7x))
step 4 :
Ddx (ln (cos(7x))) = −7xsin (7x) cos( 7x 7tan (7x)
Returning to the original equation:
1y ⋅dydx = ln (cos(7x))−7xtan(7x)
Substitute the original y as a function of x value from the start back in.
Dydx = (cos(7x))x⋅(ln(cos(7x))−7x(tan(7x)))
How many ounces does a 2-ton rhinoceros weigh?
Answer:
64,000 ounces
Step-by-step explanation:
1 ton = 32,000 ounces
2 tons x 32,000 ounces (which is equal to one ton)
=64,000 ounces
2 tons = 64,000 ounces
A 2-ton rhinoceros weighs 64,000 ounces, which is calculated by converting tons to pounds and then pounds to ounces.
Explanation:The weight of a rhinoceros weighing 2 tons can be calculated in ounces by first converting the weight to pounds. As we know from previous examples, 1 ton = 2,000 pounds. So, a 2-ton rhinoceros weighs 2 × 2,000 = 4,000 pounds. Now, to convert pounds to ounces, we use the conversion factor that 1 pound = 16 ounces. Therefore, a 2-ton rhinoceros weighs 4,000 × 16 = 64,000 ounces.

The Angle-Side-Angle postulate (ASA) states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent,
we have
∠HIG≅∠JKI ----> given problem
∠HGI≅∠JIK ----> by corresponding angles (HG and JI are parallel lines)
GI≅IK ----> given problem
so
two angles and the included side of triangle HIG are congruent to two angles and the included side of triangle JKI
therefore
triangle HIG ≅ triangle JKI ---> by ASA postulate
Remember that
If two figures are congruent, then its corresponding sides and corresponding angles are congruent

The width of a rectangle is seven meters less than the length. The perimeter is 58 meters. Find the length and width.
The length of rectangle will be 18 meters and width of rectangle will be 11 meters.
It is given that width of a rectangle is seven meters less than the length.
If perimeter of rectangle is 58 meters then find the value of length and width.
What are the area and perimeter of a rectangle ?
The area of rectangle is A = L × B and the perimeter is 2 ( L + B ) , where ; L = length and B = width.
Let's assume the length of the rectangle is x.
The width of the rectangle will be ;
= x - 7
Also ; the perimeter of triangle is given which is equal to 58 meters.
We know that ; the perimeter of triangle is given by ;
Perimeter = 2 × ( length + width )
So ;
58 = 2 [ x + (x - 7)]
58 = 2 ( 2x - 7 )
58 = 4x - 14
or
4x = 58 + 14
4x = 72
x = 72 ÷ 4
x = 18 meters
So ;
Length = 18 meters
and
Width = 18 -7 = 11 meters
Thus , the length of rectangle will be 18 meters and width of rectangle will be 11 meters.
