Answer:

1/2

Step-by-step explanation:

If the fraction of the box of pancake mix that Merida uses on Friday is not given, it is difficult to determine the exact fraction that she used on Saturday. However, if we assume that the fraction of the box of pancake mix used on Friday is 1/2 (which is a common amount for a recipe that serves 4-6 people), then we can solve for the fraction used on Saturday.

On Friday, Merida used 1/2 of the box of pancake mix.

On Saturday, she used 1 times as much pancake mix as Friday, or 1/2 * 1 = 1/2 of the box of pancake mix.

Therefore, Merida used 1/2 of the box of pancake mix on Saturday.

Note that if the fraction used on Friday is different, the fraction used on Saturday will also be different.

Find the surface area of the square pyramid shown. Label the net to help you.


I have to show work

Answers

Answer: 40 inches squared

Labels are in the pictures

Step-by-step explanation:

To find the surface area, find the area of each side.

Square (base) : side * side = 4*4 = 16

Triangle (sides) : (base * height)/2

Assuming each side is a isosceles triangle, the base 4/2 = 2

(2*6)/2 = 12/2 = 6

Since there are 4 triangles, we can multiply 6 by 4 to get the combined area. We then add the area of the square to get the final result.

6*4 + 16 = 24+16 = 40

Write each expression without the absolute value symbol. |7-(12-x)|

Answers

The expression without the absolute value symbol is given as follows:

If x > 5, then |7 - (12 - x)| = -5 + x.If x = 5, then |7 - (12 - x)| = -5 + x.If x < 5, then |7 - (12 - x)| = 5 - x.

What is the absolute value function?

The absolute value function is defined by the following piecewise rule, depending on the input of the function:

|f(x)| = f(x), x ≥ 0.|f(x)| = -f(x), x < 0.

The expression for this problem is given as follows:

7 - (12 - x).

The critical value of x is obtained as follows:

7 - (12 - x) = 0

7 - 12 + x = 0

x = 5.

Hence the expression is given as follows:

If x > 5, then |7 - (12 - x)| = -5 + x.If x = 5, then |7 - (12 - x)| = -5 + x.If x < 5, then |7 - (12 - x)| = 5 - x.

Sarah was asked to solve the following problem. Identify her errors and explain how to correct her mistakes.

Answers

Answer:

[tex]5x^3-18x^2+2x+21[/tex]

Step-by-step explanation:

In the second step, -9x-21 should be 9x+21. This is because -3 in x-3, and -3x-7 in 5x²-3x-7 are both negative, so each term's product should be positive.

Also, in the third line, she wrote -3x²-15x² as -18x⁴ instead of -18x²,and similarly, she wrote -7x-9x as -16x² (however this is wrong anyway because step 2 was done incorrectly).

If we continued off from the second step with these corrected errors:

[tex]5x^3-3x^2-7x-15x^2+9x+21\\5x^3-18x^2+2x+21[/tex]

Answers

Answer: x=108 degrees

Step-by-step explanation:

Since ST is a straight line, it measures 180 degrees.

This means that

x+(2/3)x=18


The simplified version is 5x/3=180. Now, we multiply both sides by 3. The equation becomes 5x=540 you would divide 5 by both sides which is ultimately x=108.

Answer:

x=108 degrees

Step-by-step explanation:

We know that since ST is a line, it equals a total of 180 degrees.

Let's write an equation:

[tex]180=x+\frac{2}{3}x[/tex]

simplify

[tex]180=\frac{5}{3} x[/tex]

divide both sides by 5/3

108=x

So, x=108 degrees.

At a recent football game of 8,450 in attendance, 150 people were asked what they prefer on a hot dog. The results are shown.


Ketchup Relish Chili
54 36 60


Based on the data in this sample, how many of the people in attendance would prefer chili on a hot dog?
5,070
3,380
2,986
2,084

Answers

Answer: 3,380

Step-by-step explanation: THIS IS MY GUESS.

Since we know that 150 people were surveyed, and only 60 wanted chili, we can write an equation to get the percentage of people who wanted chili as 60/150. We can simplify that to get 6/15 and then simplify again to get 2/5. 2/5 simplifies to 40% as a percentage. 40% of 8,450 (or 0.4 x 8,450) would be 3,380.

Answer 3380
Explanation
We will find the ratio of 54 36 and 60 which is 9:6;10
So now total attendance is 8450.
So 8450 * 6 / 15= 3380

Selected:b. 6 over 36This answer is incorrect.
c. 7 over 36
d. 8 over 36

Answers

Answer:

B. 6 over 36

Step-by-step explanation:

As we are given the sample space, the events that sum to 6 are:

{(1,5), (2,4), (3,3),(4,2),(5,1)}

Let n(S) be the number of items in sample space

n(S) = 36

Let E be the event the sum is 6

Then,

n(E) = 6

So,

P(Sum of two cubes is 6) = n(E) / n(S)

= 6/36

So, the correct answer is:

Step-by-step explanation:

Hi there,

We know that a pair means two and so for each pair of socks he has, we are going to multiply that number by two to find the individual amount.

White socks: 2 pairs x 2 = 4 total white socks

Black socks: 4 pairs x 2 = 8 total black socks

Blue socks: 1 pair x 2 = 2 total blue socks.

Now, you add up the total amount of individual socks in the drawer.

4+8+2 = 14 socks.

We are trying the find the probability that he is going to pick a black sock.  The amount of black socks is going to go on the numerator of the fraction and the total amount of socks in the drawer is going to go on the denominator.

8 black socks  /  14 total socks

Now that we have this fraction, we need to simplify it.  The number 8 and 14 are both divisible by 2, so we now have the fraction (4/7).

What this means is that, theoretically, if he randomly pulled out 7 socks, that 4 of the socks he pulls out should be black, leaving the probability he picks out black socks to be (4/7) of the time or about 57% likely to happen.

Work out the area of the trapezium
(some please help, i forgot how to do this )

Answers

Answer:

48cm

Step by step:

The area of a trapezoid can be found using the formula A=(1/2)(b1+b2)h, so we replace each variable with what is written on the trapezoid. A=(1/2)(7+9)(6), so once you simplify you get 48.

Answer:

The area of the Trapezium is 48cm².

Step-by-step explanation:

A trapezium has a pair of Parallel Lines.

Let’s mark the line that is on the top as A and the bottom one as B.

Length of line A (Base 1) = 7cm

Length of line B (Base 2) = 9cm

Height of Trapezium = 6cm

Area of Trapezium (Formula) = {( Base 1 + Base 2 ) / 2} * Height

                                                 = {( 7cm + 9cm ) / 2} * 6cm

                                                 = ( 16cm / 2 ) * 6cm

                                                 = 8 cm * 6cm

                                                 = 48cm²

The area of the Trapezium is 48cm².

Formula

Area of the rectangle = bh

The value of π is 3.14

Area of the semicirlce
