Answer:
6 Slices Of Cheese Remaining
Step-by-step explanation:
50% of the cheese is 16 slices, so add on 50% + 25% and you get 24 slices...
if you do 32-24 you have 8 slices remaining and if you eat 25% of the 8 slices you have 6 slices left.

if 9450 is 16%, how much is 100%
Answer:
59062.50
Step-by-step explanation:
Is means equals
9450 = 16% of a number
9450 = .16 N
divide by .16
9450/.16 = .16N/.16
59062.50 = N
The number is 59062.50
We want 100% of the number which is all of it

identify the center and the radius of a circle with equation (x-4)^2+(y+2)^2=9
Answer:
center:(4,-2)
Radius: 3 units
Step-by-step explanation:
The standard equation of a circle is given as [tex](x-h)^2+(y-k)^2=r^2[/tex], where (h,k) is the center and r is the radius of the circle.
The given equation is [tex](x-4)^2+(y+2)^2=9[/tex].
We compare to the standard equation of the circle to get;
[tex]x-h=x-4[/tex]
[tex]\Rightarrow -h=-4[/tex]
[tex]\Rightarrow h=4[/tex]
and
[tex]y-k=y+2[/tex]
[tex]\Rightarrow -k=2[/tex]
[tex]\Rightarrow k=-2[/tex]
Hence the center of the circle is (4,-2).
Also, we have [tex]r^2=9[/tex]
Therefore [tex]r=\sqrt{9}[/tex]
[tex]r=3[/tex] units.
Answer:
Center at (4,-2); radius: 3

What is the factored form of x2 - 12x - 45?
Answer:
(x - 15)(x + 3)
Step-by-step explanation:
Factors of 45 include 5 and 9, 3 and 15, 1 and 45, and so on.
Note that 3*15 =+45; this is not what we wanted. Thus, try (-3)*15 = -45.
Do -3 and 15 combine to yield -12? No. Thus drop (-3)(15) and try (3)(-15).
Do 3 and -15 combine to yield -12? YES
Therefore, the factored form of x² - 12x - 45 is (x - 15)(x + 3).

A group of art students are painting a mural on a walls the rectangular wall has dimensions of (6x+7) by (8x+5) and they are planning the mural to be (x+4) by(2x+5). What is the area of the remaining wall after the mural has been painted
Answer:
46x^2 + 73x + 15
Step-by-step explanation:
Expand both equations
Wall = (6x + 7)(8x + 5) = 48x^2 + 56x + 30x + 35 = 48x^2 + 86x + 35
Mural = (x + 4)(2x + 5) = 2x^2 + 5x + 8x + 20 = 2x^2 + 13x + 20
Minus them.
Wall - Mural =
(48x^2 + 86x + 35) - (2x^2 + 13x + 20)
(48x^2 - 2x^2) + (86x - 13x) + (35 - 20)
46x^2 + 73x + 15
Answer:
46x^2 + 73x + 15
Step-by-step explanation:
Expand both equations
Wall = (6x + 7)(8x + 5) = 48x^2 + 56x + 30x + 35 = 48x^2 + 86x + 35
Mural = (x + 4)(2x + 5) = 2x^2 + 5x + 8x + 20 = 2x^2 + 13x + 20
Minus them.
Wall - Mural =
(48x^2 + 86x + 35) - (2x^2 + 13x + 20)
(48x^2 - 2x^2) + (86x - 13x) + (35 - 20)
46x^2 + 73x + 15

64−(3y+8y+y)÷40=37
8,000÷(28x+4)−15=25
Answer:
y = -118 and x = 7
Step-by-step explanation:
I've attached a picture with my work.
Detailed steps on solving equations with variables y and x, including simplification and solving for the unknowns.
Solving the equation 64−(3y+8y+y)÷40=37:
Combine like terms: 64 - (12y) ÷ 40 = 37Simplify: 64 - 0.3y = 37Solve for y: y = (64 - 37) / 0.3 = 90Solving the equation 8,000÷(28x+4)−15 = 25:
Add 15 to both sides: 8,000 ÷ (28x + 4) = 40Multiply both sides by (28x + 4): 8,000 = 40(28x + 4)Solve for x: x = (8,000 - 160) / 40(28) = 6Brenda walk the dogs after school she is planning to increase the rate that she charges by 20% in January when does current rate for walking a dog is $4.50 what will be the new rate in dollars after the 20% increase? Plz show work
Answer:
$5.40
Step-by-step explanation:
To find the increase we need to consider our variables.
Current Rate = $4.50
Increase Percentage = 20% or 0.20
Now we can find the new rate by multiplying the Current Rate to the Increase Percentage and add it to the Current Rate again.
Total Price w/ Increase = ($4.50 x 0.20) + $4.50
Total Price w/ Increase = $0.90 + $4.50
Total Price w/ Increase = $5.40

. Evaluate the following expression: 24 ÷ 3 + 7 ⋅ 2 – 15 ÷ 5 + 6 ⋅ 2 A. 31 B. –31 C. 30 D. 21
To evaluate the expression, we follow the order of operations (PEMDAS). The result of the expression is 31.
Explanation:To evaluate the expression 24 ÷ 3 + 7 ⋅ 2 – 15 ÷ 5 + 6 ⋅ 2, we need to follow the order of operations, also known as PEMDAS. PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
First, we perform the division: 24 ÷ 3 = 8.Next, we perform the multiplication: 7 ⋅ 2 = 14 and 6 ⋅ 2 = 12.Now, we can write the expression with the values we found: 8 + 14 - 15 ÷ 5 + 12.Then, we perform the division: 15 ÷ 5 = 3.Finally, we perform the addition and subtraction from left to right: 8 + 14 - 3 + 12 = 31.Therefore, the evaluated expression is equal to 31.
Define the following terms
a. Dividend

Answer:
11x - y = -79Step-by-step explanation:
The standard form of an equation of a line:
[tex]Ax+By=C[/tex]
The point-slope form of an equation of a line:
[tex]y-y_1=m(x-x_1)[/tex]
m - slope
(x₁, y₁) - point
We have the points (-7, 2) and (-8, -9). Substitute:
[tex]m=\dfrac{-9-2}{-8-(-7)}=\dfrac{-11}{-1}=11[/tex]
[tex]y-2=11(x-(-7))\\\\y-2=11(x+7)[/tex]
Convert to the standard form:
[tex]y-2=11(x+7)[/tex] use the distributive property a(b + c) = ab + ac
[tex]y-2=11x+77[/tex] add 2 to both sides
[tex]y=11x+79[/tex] subtract 11x from both sides

➷ You have written it the incorrect way.
Following the rules of PEMDAS, the multiplication would be carried out before the addition. This is not what is wanted

Show that sin (x + pi) = -sin x.
Answer:
The answer in the procedure
Step-by-step explanation:
we know that
[tex]sin(A + B) = sin A cos B + cos A sin B[/tex]
In this problem we have
[tex]sin(x + \pi)=sin (x)cos(\pi) + cos(x)sin(\pi)[/tex]
Remember that
[tex]sin(\pi) = 0[/tex]
[tex]cos(\pi) = -1[/tex]
substitute
[tex]sin(x + \pi) = sin(x)(-1) + cos(x)(0)[/tex]
[tex]sin(x + \pi) = -sin(x)[/tex]
Final answer:
To prove that sin (x + π) = -sin x, the trigonometric identity for the sine of a sum is used, and by considering the specific values for cos π and sin π, the identity simplifies to the required expression.
Explanation:
To show that sin (x + π) = -sin x, we can use the trigonometric identity for the sine of a sum:
sin (α + β) = sin α cos β + cos α sin β
Applying this identity to sin (x + π):
sin (x + π) = sin x cos π + cos x sin π
Since cos π = -1 and sin π = 0, we substitute these values:
sin (x + π) = sin x (−1) + cos x (0)
sin (x + π) = −sin x + 0
Hence, sin (x + π) = −sin x, demonstrating the original statement.
some of the dimensions, in meters, of a different swimming pool that is a rectangular from the top and trapezoidal from the side are shown. what is the volume, in cubic meters, if the water in the pool when it is completely full?
Answer:
[tex]4,151.25\ m^{3}[/tex]
Step-by-step explanation:
we know that
The volume of the trapezoidal prism (swimming pool) is equal to
[tex]V=BL[/tex]
where
B is the area of the trapezoidal base
L is the length (distance between the two trapezoidal faces)
Find the area B
[tex]B=\frac{1}{2}(4+8)(30.75)=184.5\ m^{2}[/tex]
[tex]L=22.5\ m[/tex]
Find the volume
[tex]V=184.5(22.5)=4,151.25\ m^{3}[/tex]
Order the numbers from least to greatest.
* The square root of 1/64
*1/4
*0.2 repeating
From least to greatest, the numbers are
Answer:
Step-by-step explanation:
The sqrt of 1/64 is 1/8, or 0.125.
1/4 is equivalent to 0.25.
0.2 repeating is 0.222222222222 ...
Least: 0.125
Middle: 0.25
Greatest: 0.222222222222 ...
The numbers from least to greatest are: square root of 1/64 (0.125), 0.2 repeating (0.222...), and 1/4 (0.25).
Explanation:This problem requires an understanding of fractions and square roots to order the numbers correctly. Firstly, you have to calculate the square root of 1/64. The square root of 1/64 is 1/8 or 0.125. Then, let's consider the other numbers: 1/4 which is equal to 0.25, and 0.2 repeating which is actually equivalent to 0.222 continuing. Now we can order them from least to greatest: 1/8 (0.125), 0.2 repeating (0.222...), and 1/4 (0.25).
