Cara's first error occurred when she simplified the expression (negative 4) squared.

According to the order of operations (PEMDAS/BODMAS), exponentiation should be performed before any other operations. However, Cara incorrectly squared only the negative sign and not the entire number.

As a result, she obtained a value of positive 4 instead of 16.

To correct the error, Cara should have squared the entire value of -4. Squaring a negative number yields a positive result. Thus, (-4) squared is equal to 16. By failing to correctly apply this rule, Cara ended up with an incorrect value in her expression.

The correct evaluation of the expression should have been:

StartFraction 4 (7 minus 13) over 3 EndFraction + (negative 4) squared minus 2 (6 minus 2) = StartFraction 4 (-6) over 3 EndFraction + 16 minus 2 (4) = -8 + 16 - 8 = 0.

Therefore, Cara's first error was in incorrectly squaring only the negative sign and obtaining a value of 4 instead of 16.

The correct value of volume of the pyramid is 48 cubic inches.

To find the volume of the solid oblique pyramid, we can use the formula V = (1/3) * Base Area * Height. The base of the pyramid is a triangle, and the height is given as 6 inches.The formula for the area of a triangle is (1/2) * base * height. In this case, the base length is 8 inches and the height is 6 inches. Base Area = (1/2) * 8 * 6 = 24 square inches

Now, we can calculate the volume of the pyramid:

V = (1/3) * Base Area * Height

V = (1/3) * 24 * 6

V = 48 cubic inches

Answer:

I can't understand the language but try people who can

Answer:

Step-by-step explanation:

I understand your confusion. Let's go through the steps together to solve the equation correctly:

Given equation: 5 + x - 12 = 2x - 7

Combine like terms on the left side and the right side of the equation:

x - 7 = 2x - 7

Now, let's isolate the variable x. Subtract x from both sides of the equation:

x - x - 7 = 2x - x - 7

Simplifying:

-7 = x - 7

Next, add 7 to both sides of the equation:

-7 + 7 = x - 7 + 7

Simplifying:

0 = x

Therefore, the solution to the equation is x = 0.

If you need to use the values x = -4, 0, and 5, you can substitute each value into the original equation to check if it satisfies the equation. Let's do that:

For x = -4:

5 + (-4) - 12 = 2(-4) - 7

-11 = -15 - 7

-11 = -22

The equation is not satisfied for x = -4.

For x = 0:

5 + 0 - 12 = 2(0) - 7

-7 = -7

The equation is satisfied for x = 0.

For x = 5:

5 + 5 - 12 = 2(5) - 7

-2 = 3

The equation is not satisfied for x = 5.

Therefore, the correct solution to the equation is x = 0. The values x = -4 and x = 5 do not satisfy the equation.

Answer:

she mixed up the slope and y- intercept in step 3

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

she correctly calculated the slope as m = - 4 and the y- intercept b = - 3

thus equation she should have is

y = - 4x - 3

Brooke's error was that she found the incorrect slope in step 1.  

The slope formula is:  m = (y₂ - y₁) / (x₂ - x₁)  

Using the given points:  m = (13 - 25) / (-4 - (-7))  m = -12 / 3  m = -4  

So, the slope is -4, not -12/3 as Brooke calculated in step 1.  

The correct equation for the line passing through the points (-7, 25) and (-4, 13) is: y = -4x - 3 (as found in step 3)

Step-by-step explanation:

Hours worked on Friday:  6 hr and 30 min = 6.5 hr

Money earned on Friday:  $15.5/hr x 6.5 hr = $100.75

Hours worked on Saturday:  6.5 hr - 1.167 hr = 5.33   *10 min = 10/60 = 0.1667 hr

Money earned on Saturday:  $15.50 x 5.33 hr = $82.67

Hours worked on Monday:  4.167 hr

Money earned on Monday:  $15.50/hr x 4.167 hr = $64.58

Answer:

Therefore, the cost of a pen is $2.30.

Step-by-step explanation:

Let's assign variables to represent the cost of a calculator and the cost of a pen.

Let c represent the cost of a calculator.

Let p represent the cost of a pen.

Based on the given information, we can form the following pair of simultaneous equations:

Equation 1: 4c + 2p = 20.60   (Mia buys 4 calculators and 2 pens for $20.60)

Equation 2: 5c + 3p = 26.90   (Heidi buys 5 calculators and 3 pens for $26.90)

To solve for the cost of a pen, we'll eliminate the variable c by multiplying Equation 1 by 5 and Equation 2 by 4. Then we'll subtract Equation 1 from Equation 2:

5 * (4c + 2p) = 5 * 20.60

4 * (5c + 3p) = 4 * 26.90

20c + 10p = 103.00

20c + 12p = 107.60

Subtracting Equation 1 from Equation 2:

(20c + 12p) - (20c + 10p) = 107.60 - 103.00

20c - 20c + 12p - 10p = 4.60

2p = 4.60

p = 4.60 / 2

p = 2.30

Therefore, the cost of a pen is $2.30.

Answer:

Let's assume that the cost of a calculator is x and the cost of a pen is y. Then we can write the following pair of equations:

4x + 2y = 20.60    (equation 1)

5x + 3y = 26.90    (equation 2)

To solve for the cost of a pen, we need to eliminate x from the equations. We can do this by multiplying equation 1 by 5 and equation 2 by -4, and then adding them:

(5)(4x + 2y = 20.60)  becomes  20x + 10y = 103    (equation 3)

(-4)(5x + 3y = 26.90) becomes -20x - 12y = -107.60    (equation 4)

Adding Equation 3 and Equation 4 gives:

-2y = -4.60

Divide both sides by -2:

y = 2.30

Therefore, the cost of a pen is $2.30.

Answer:

Step-by-step explanation:

To find the maximum width of an aircraft seat that will accommodate 98% of all adult women, we need to determine the corresponding z-score for the 98th percentile of the normal distribution.

First, we find the z-score corresponding to the 98th percentile using a standard normal distribution table or calculator. The z-score for the 98th percentile is approximately 2.05.

Next, we use the z-score formula to find the corresponding value in the original distribution:

z = (x - μ) / σ

Solving for x (the maximum width of the aircraft seat):

x = z * σ + μ

Substituting the values given:

x = 2.05 * 4.36 + 37.6

x ≈ 45.98

Therefore, the maximum width of an aircraft seat that will accommodate 98% of all adult women is approximately 46 cm (rounded to one decimal place).

Answer:

Step-by-step explanation:

To solve the equation (2/3)t - (1/5)t = 2 for t, we need to combine like terms and isolate the variable t. Here are the steps:

(2/3)t - (1/5)t = 2

To combine the fractions, we need to find a common denominator for 3 and 5, which is 15.

[(2/3)(5/5)]t - [(1/5)(3/3)]t = 2

(10/15)t - (3/15)t = 2

[(10 - 3)/15]t = 2

(7/15)t = 2

To isolate t, we can multiply both sides of the equation by the reciprocal of (7/15), which is (15/7).

[(7/15)t][(15/7)] = 2[(15/7)]

t = (2 * 15) / 7

t = 30/7

Therefore, the solution for t in the equation (2/3)t - (1/5)t = 2 is t = 30/7 or t ≈ 4.286.

The ordered pair given in the first row of the table can be written using function notation as (x, f(x)) = (-6, 8).

f(x) = -5 when x is 4.

In function notation, we represent the input value as 'x' and the corresponding output value as 'f(x)'.

Looking at the first row of the table, we see that when x is -6, the corresponding value of f(x) is 8.

Therefore, we can write this ordered pair as (-6, 8) in function notation.

Similarly, we can determine that f(x) = -5 when x is 4 by examining the second row of the table.

The value of f(x) is -5 when x is 4, so we can express it as f(4) = -5.

The equation to determine the initial amount of money Cecilia had is x = 0.

Let's denote the initial amount of money Cecilia had as "x" dollars.

According to the given information, Cecilia spent one-fourth (1/4) of her money on a book, which is (1/4)x dollars. After buying the book, she had (x - (1/4)x) dollars left.

Next, Cecilia spent half (1/2) of the remaining money on a comic, which is ((1/2)x - 8) dollars. After buying the comic, she had ((x - (1/4)x) - ((1/2)x - 8)) dollars remaining.

Since she had $8 left, we can set up the equation:

((x - (1/4)x) - ((1/2)x - 8)) = 8

To simplify the equation, we can first combine like terms:

(x - (1/4)x - (1/2)x + 8) = 8

Now, let's solve the equation step by step:

(x - (1/4)x - (1/2)x + 8) = 8

Multiplying the fractions by their common denominator, which is 4, we get:

(4x - x - 2x + 32) = 32

Simplifying further:

(x + 32) = 32

Subtracting 32 from both sides:

x = 0

Therefore, the equation to determine the initial amount of money Cecilia had is x = 0.
