Answer:
200 cakes
Step-by-step explanation:
1) divide 80 by 2 to get 40
2) times 40 by 5 50 get 200
answer is 200 cakes sold on Tuesday
On Tuesday, the cafe sold 200 cakes which is the ratio of the number of cakes sold to the number of scones sold was 5:2.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other. Proportions are represented by the symbols "::" or "=".
We have been given that the ratio of the number of cakes sold to the number of scones sold was 5:2, on Tuesday.
On Tuesday, the cafe sold 80 scones.
Let's assume that x number of cakes sold on Tuesday
According to the given condition, the proportion would be
5 cakes : 2 scones = x cakes : 80 scones
⇒ 5/2 = x /80
Apply the cross multiplication,
⇒ 5 × 80 = 2x
⇒ 400 = 2x
⇒ 2x = 400
⇒ x = 400/2
⇒ x = 200
Therefore, on Tuesday, the cafe sold 200 cakes.

Manuel incorrectly claimed that the surface area of the cylinder shown is about 190.0 in.2. Use a formula to find the surface area of the cylinder. Use 3.14 for π. What was his likely error?
The likely error in Manuel's claim is 552.61 in².
We have,
Height = 16 in
Diameter = 11 in
radius = 5.5 in
The surface area of a cylinder.
= 2πrh + 2πr²
= 2 x 3.14 x 5.5 x 16 + 2 x 3.14 x 5.5²
= 552.64 + 189.97
= 742.61 in²
Now,
Manuel incorrectly claimed that the surface area of the cylinder is
190.0 in²
Error = Correct surface area - Claimed surface area
Error = 742.61 in² - 190.0 in²
Error ≈ 552.61 in²
Thus,
The likely error in Manuel's claim is 552.61 in².

Help!!! What is the difference ? (x - 8)/(3x) - (3x)/(x ^ 2)
Answer:
Given that you're providing only a single term, asking for a difference doesn't make a lot of sense. I assume you're asking to have the expression simplified?
If so, then it can be reduced to (x - 17) / 3x
Step-by-step explanation:
You can simplify by multiplying both terms each by a different ratio that equals one, but also gives the terms common denominator. Multiplying the first one by x²/x² and the second by 3x/3x will do that for you.
After that you can group the terms into one fraction and simplify:
[tex]\frac{x - 8}{3x} - \frac{3x}{x^2} \\\\= \frac{x - 8}{3x}\times\frac{x^2}{x^2} - \frac{3x}{x^2} \times\frac{3x}{3x} \\\\= \frac{x^3 - 8x^2}{3x^3} - \frac{9x^2}{3x^3} \\\\= \frac{x^3 - 8x^2 - 9x^2}{3x^3} \\\\= \frac{x - 8 - 9}{3x}\\\\= \frac{x - 17}{3x}\\[/tex]
Answer:
The difference of [tex]\frac{x-8}{3x}-\frac{3x}{x^2}[/tex] is [tex]\mathbf{\frac{x-17}{3x}}[/tex]
Step-by-step explanation:
We need to find the difference: [tex]\frac{x-8}{3x}-\frac{3x}{x^2}[/tex]
Simplifying to find the difference:
[tex]\frac{x-8}{3x}-\frac{3x}{x^2}[/tex]
x is common in both 3x and x^2 so, we can cancel it out and we get:
[tex]=\frac{x-8}{3x}-\frac{3x}{x(x)}\\=\frac{x-8}{3x}-\frac{3}{x}[/tex]
Now, taking LCM of 3x and x we get 3x, We will multiply 3x with both terms and then solve we get:
[tex]=\frac{x-8-3(3)}{3x}\\=\frac{x-8-9}{3x}\\=\frac{x-17}{3x}[/tex]
It cannot be further simplified, so we get [tex]\frac{x-17}{3x}[/tex] as answer.
So, The difference of [tex]\frac{x-8}{3x}-\frac{3x}{x^2}[/tex] is [tex]\mathbf{\frac{x-17}{3x}}[/tex]
A fish tank has 150 gallons of water and is being drained at a rate of 1/2 gallon each second. A fish tank has 120 gallons of water and is being filled at a rate of 1/4 gallon each second. After how many seconds will the ywo fish tanks have the same amount of water?
Answer:
40! Seconds
Step-by-step explanation:
Calculation for After how many seconds will the two fish tanks have the same amount of water
First step
Based on the information given let the equation be :
150-1/2x=120+1/4x
Second step
Now let solve for x which means that x will be the number of second by multiplying both side by 4
4(150-1/2x)=4(120+1/4x)
=600-2x=480+x
Third step
Let Add 2x on both side
600=480+3x
Third step
Let Subtract 480 on both side
600-480=480-480+3x
120=3x
Last step is to divide both side by 3
120/3=3x/3
40=x
Hence:
x=40 seconds
Therefore After 40 seconds the two fish tanks will have the same amount of water.

Answer:
(a) When a = 4 and b = -5, a² + b² - a·b = 61
(b) When a = 4 and b = -5, a³·b + a·b² = -220
(c) [tex]When \ a = 4 \ and \ b = -5, \ \dfrac{a - b}{a + b} + a -b = 0[/tex]
(d) When a = 4 and b = -5, (a + b)² - (a - b)² = 82
Step-by-step explanation:
The question relates to evaluation of expressions, given the values of the variables, "a" and "b"
Where;
a = 4 and b = -5
(a) For a² + b² - a·b, we have;
a² + b² - a·b = 4² + (-5)² - 4 × (-5) = 16 + 25 + 20 = 41 + 20 = 61
(b) For a³·b + a·b² we have;
a³·b + a·b² = 4³·(-5) + 4·(-5)² = 64 × (-5) + 4 × 25 = -320 + 100 = -220
(c) For [tex]\dfrac{a - b}{a + b} + a -b[/tex], we have;
[tex]\dfrac{a - b}{a + b} + a -b = \dfrac{4 - (-5)}{4 + (-5)} + 4 - (-5) = \dfrac{4 + 5}{4 -5} + 4 + 5= \dfrac{9}{-1} + 4 + 5 = -9 + 4 + 5 = 0[/tex]
[tex]\therefore when \ a = 4 \ and \ b = -5, \ \dfrac{a - b}{a + b} + a -b = 0[/tex]
(d) For (a + b)² - (a - b)² we have;
(a + b)² - (a - b)² = (4 + (-5))² - (4 - (-5))² = (4 - 5)² - (4 + 5)² = (-1)² - 9² = 1 + 81 = 82
When a = 4 and b = -5, (a + b)² - (a - b)² = 82

Answer:
FalseStep-by-step explanation:
Line a
y = 5x - 6, it has slope of 5Line b
x + 5y = 5Rewrite in slope-intercept form to find its slope:
5y = -x + 5y = -1/5x + 1It has slope of -1/5Lines have different slopes: 5 and -1/5, therefore are not parallel
Answer:
The answer to the question provided is False.
Step-by-step explanation:
‣We are going to have to find the value of y for line b.
‣We are going to solve its equation.
[tex]x + 5y = 5 \\ \frac{- x \: \: \: \: \: = - x}{ \frac{5y}{5} = \frac{ - x + 5}{5} } \\ y = - \frac{1}{5} x+ 1[/tex]
‣So we have:
[tex]y = 5x - 6 \\ and \\ y = - \frac{1}{5} x + 1[/tex]
‣Remember that a slope is parallel to another slope if it has the same slope.
‣A slope is perpendicular to another slope if it has a negative reciprocal.
‣The slopes we have don't have the same slope, but they are perpendicular.
