Let the total number of apples in the basket be m

12% of the apples are rotten, and apples in good condition are 66

Therefore, according to the question,

[tex]88\% \: of \: m= 66[/tex]

[tex]→ \frac{88}{100}× m = 66[/tex]

[tex]→ m = \frac{(66 \times 100)}{88} [/tex]

[tex]→ m = 3 \times 25[/tex]

[tex]→ m = 75[/tex]

Therefore, total number of apples in the basket is 75.

[tex]\red\bigstar \huge \color{blue}{ \tt{answer}}[/tex]

Let the total number of apples in the basket be x

• The apples are rotten = 12%

• The apples in good condition = 66

So ,

[tex]\bold{88\% \: of \: x = 66 }[/tex]

[tex] \bold{↪\frac{88}{100} × x = 66 }[/tex]

[tex]\bold{↪x = \frac{(66×100)}{88} }[/tex]

Given that triangles OPQ and RST are similar triangles, the measure of side ST is: 75.3.

The ratio of the corresponding sides of two similar triangles are always equal, meaning the sides are proportional to each other.

Given:

Since Triangle OPQ is similar to triangle RST, therefore:

RS/OP = ST/PQ

Substitute

RS/17 = 31/7

Cross multiply

RS = (31 × 17)/7

RS = 75.3

The error that Barbara's made is that Barbara wrote (d+63) instead of (d+9).

The distributive property of multiplication is that when two numbers are added such as (a+b) and multiplied by a third number such as x, then the result will be the sum of multiplication of the third number with the first number (xa) and the third number with the second number (xb).

x(a+b) = xa + xb,

The expression which is equal to the expression 7d+63 can be written as,

[tex]7d+63\\\\=7(d+9)[/tex]

Question: Quadrilateral GABE is a square. Assume that point A is the centre of the circle. If the circumference (perimeter of a circle) is 201 ft., find AE.

Solution:

πd = C

πd = 201

3.14(d) = 201

diameter  = 64.01

radius is half of the diameter.

radius = 64.01/2

radius = 32

GA = 32

As its sqaure, all sides are equal

GA  = AB = GE = EB = 32

using Pythagoras theorem:

32² + 32² = AE²

AE = √2048.8

AE = 45.3 ft

Answer:

Step-by-step explanation:

C = πd = 2πr

201 = 2*3.14*AB

AB = 201 / (2*3.14) = 32

AE is the diagonal of square ABEG

Using Pythagoras theorem,

AE^2 = AB^2 + BE^2 = 2*AB^2

AE^2 = 2*32^2

AE = sqrt(2*32^2)

= 45.255

= 45.3 ft

The sample of the speeds of 20 cars and at a 0.05 confidence level, we

have;

(a) There is not enough convincing evidence to suggest that the true mean speed of all cars travelling on Elm Street is more than 25 mph

(b) Type II error

(a) Based on the given data, using MS Excel, we have;

The sample size, n = 20

The mean, [tex]\overline x[/tex] = 25.86

The standard deviation of the sample, s = 2.284

The null hypothesis, H₀; [tex]\overline x[/tex] = 25 mph

Alternative hypothesis, Hₐ; [tex]\overline x[/tex] > 25 mph

Given that the sample size is less than 30, the t-test is used, and the t-score is found as follows;

[tex]t= \mathbf{\dfrac{\bar{x}-\mu }{\dfrac{s}{\sqrt{n}}}}[/tex]

Which gives;

[tex]t=\dfrac{25.86-25 }{\dfrac{2.284}{\sqrt{20}}} \approx \mathbf{1.684}[/tex]

Using a graphing calculator, we have;

The probability ≈  0.054

The critical-t ≈ 1.729

Given that the probability is larger than the significance level, we fail to

reject the null hypothesis.

There is not enough convincing statistical evidence to conclude that the

true mean of all cars travelling on Elm Street is more than 25 mph.

(b) The type of error is Type II error, given that there is a possibility that

the null hypothesis is failed to be rejected when it is actually false.

Given that the sample size is less than 30, it may be insufficient for the

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To calculate the interest Ivy will receive at the end of one year, we need to multiply the amount she invested by the interest rate:

Interest = Principal x Rate

Here, the principal is $150,000 and the rate is 0.2% or 0.002 (as a decimal):

Interest = $150,000 x 0.002

Interest = $300

Answer:

  (x, y) = (-1/6, 1/4)

Step-by-step explanation:

This is a system of equations in expressions of two variables. You could solve it by expanding the expressions to the base variables, or you could solve it by first finding the values of the expressions.

Let's see what happens when we expand the equations all the way.

First equation:

  [tex]\dfrac{1}{2}(x +2y)+\dfrac{5}{3}(3x-2y)=-\dfrac{3}{2}\\\\3(x+2y)+10(3x-2y)=-9\qquad\text{multiply by 6}\\\\3x+6y+30x-20y=-9\qquad\text{eliminate parentheses}\\\\\boxed{33x-14y+9=0}\qquad\text{collect terms, add $9$ to get general form}[/tex]

__

Second equation:

  [tex]\dfrac{5}{4}(x+2y)-\dfrac{3}{5}(3x-2y)=\dfrac{61}{60}\\\\75(x+2y)-36(3x-2y)=61\qquad\text{multiply by 60}\\\\75x+150y-108x+72y=61\qquad\text{eliminate parentheses}\\\\-33x +222y = 61\qquad\text{collect terms}\\\\\boxed{33x-222y+61=0}\qquad\text{write in general form}[/tex]

__

The solution process looks like it might be messy for either substitution or elimination, so we choose to solve these equations using the cross-multiplication method.

  Δ1 = (33)(-222) -(33)(-14) = -6864

  Δ2 = (-14)(61) -(-222)(9) = 1144

  Δ3 = (9)(33) -(61)(33) = -1716

  x = Δ2/Δ1 = 1144/-6864 = -1/6

  y = Δ3/Δ1 = -1716/-6864 = 1/4

The solution is (x, y) = (-1/6, 1/4).

_____

Additional comment

The weird numbers notwithstanding, the solution by elimination might be easily achieved by subtracting the second equation from the first. This would give ...

   208y -52 = 0   ⇒   y = 52/208 = 1/4

Direct substitution of this into either equation will require arithmetic with fractions to obtain the solution for x.

This system can be directly solved by a graphing calculator using the equations as given.

Step-by-step explanation:

Given equation are: [1/{2(x+2y)}] + [5/{3(3x-2y)}] = -3/2 →Eqn(1)

[5/{4(x+2y)}] - [3/{5(3x-2y)}] = 61/60 →Eqn(2)

Let {1/(x+2y)} = a ; {1/(3x-2y)} = b then

{1/(2a)} + {5/(3b)} = -3/2 →Eqn(3) * 5/2

{5/(4a)} - {3/(5b)} = 61/60 →Eqn(4) * 1

__________________________________

{5/(4a)} + {25/(6b)} = -15/4

{5/(4a)} - {3/(5b)} = 61/60

(-) (+) (-)

______________________

{23/(6b)} + {3/(5b)} = -(15/4) - (61/60)

⇛{(125b + 18b)/(30b²)} = {(-225 - 61)/60}

⇛{(143b)/(30b²)} = -286/60

⇛{143/(30b)} = -286/60

⇛1/b = -1

Therefore, b = -1

Substitute the value of b in equation (3) then we have

{1/(2a)} + (5/3) = -3/2

⇛{1/(2a)} = -(3/2) - (5/3)

= (-9-10)/6

⇛{1/(2a)} = -19/6

⇛1/a = -19/3

a = -3/19

Now, {1/(x+2y)} = a ⇛-3/19

⇛x+2y = -19/3. ⇛3x + 6y = -19 →Eqn(5)

{1/(3x-2y)} = 1⇛ 3x - 2y = 1 →Eqn(6)

(-) (+) (-)

______________

8y = -20

y = -20/8

From equation (6)

3x - 2 * (-5/2) = 1

⇛3x - 5 = 1

⇛3x = 1+5

⇛3x = 6

⇛x = 6/3

Answer: Hence, the required value of x and y with be -5/2 and 2 respectively.
