Jill is baking an apple pie. She cuts each apple into rectangular prism pieces and length 1 inch, width 1/4 inch, and height 1/2 inch. In total, she cuts 528 apple slices. What is the volume of each slice? What is the volume of all of the cut apples?

Answers

Step-by-step explanation:

Area of Rectangle Prism = Area of base x height

= Length x Width x Height

[tex] = 1 \times \frac{1}{4} \times \frac{1}{2} \\ = 0.125 {in}^{3} [/tex]

One Apple Pie =

[tex]0.125 {in}^{3} [/tex]

Volume of 528 Apple Pies = Volume of 1 apple pie x 528

=

[tex]0.125 \times 528 \\ = 66 {in}^{3} [/tex]

Answers

Step-by-step explanation:

You can use a confidence interval (CI) for hypothesis testing. In the typical case, if the CI for an effect does not span 0 then you can reject the null hypothesis. But a CI can be used for more, whereas reporting whether it has been passed is the limit of the usefulness of a test.

Find the slope of the line that contains the points named.
K(c + d, c-d), L(c-d, c+ d)

A.0
B.-1
C 1​

Answers

Answer:

        B.   - 1

Step-by-step explanation:

The slope of the line passing through two given points:  [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

K(c + d, c-d)   ⇒     x₁ = c + d,     y₁ = c - d

L(c-d, c+ d)   ⇒      x₂ = c - d,     y₂ = c + d

So, the slope:

                     [tex]m=\dfrac{c+d-(c-d)}{c-d-(c+d)}=\dfrac{c+d-c+d}{c-d-c-d}=\dfrac{2d}{-2d}=-1[/tex]

Find the area of the trapezoid. Pls explain and I will mark brainliest.

Answers

Answer:

B. 191.4 m²

Step-by-step explanation:

Split the trapezoid as pictured below

Find its height and the upper base, then find the area of the trapezoid.

There are 3 pieces, two of them are 45°×45° and 30°×60°×90° triangles

The ratio of sides of a 30°×60°×90° triangle is  1 : √3 : 2The legs of a 45x45 triangle are equal

The above mentioned properties give us:

h = 16/2 = 8 m b = 8√3 ≈ 13.85 ma = h = 8 m

Now find the area:

A = 1/2( 13 + 8 + 13.85 + 13)*8 = 191.4 m²

Correct choice is B

Primary school students are playing hide and seek at recess as the counting begins Jon runs 100 feet east , turns 45 degrees north of east and runs another 120 feet to find a hiding spot . Lisa finds her hiding spot by running 120 feet west , turning 32 degrees south of west , and continuing another 100 feet which students hiding spot is closer to starting point ?

Answers

Answer:

Jon's hiding spot is closer to the starting point.

Step-by-step explanation:

Jon's final position forms a triangle with sides 100 ft and 120 ft respectively with an angle of 180 - 45 = 135 between them. Since the angle between the 100 ft direct east and 120 ft direction is 45, since Jon turns 45 after moving for 100 ft and then moves another 120 ft to his final destination.

Also, Lisa's final position forms a triangle with sides 120 ft and 100 ft respectively with an angle of 180 - 32 = 148 between them. Since the angle between the 120 ft direction west and 100 ft direction south of west is 45, since Lisa turns 32 after moving for 120 ft and then moves another 100 ft to her final destination.

Using the cosine rule,

a² = b² + c² - 2abcosФ,  we find the length of the third side of each triangle which is their distance from the starting point.

So, for Jon

a² = b² + c² - 2abcosФ where b = 100 ft, c = 120 ft and Ф = 135°

Thus,

a² = (100 ft)² + (120 ft)² - 2(100 ft)(120 ft)cos135°

a² = 10000 ft² + 14400 ft² - 24000 ft²cos135°

a² = 10000 ft² + 14400 ft² - 24000 ft²(-0.7071)

a² = 24400 ft² + 16970.56 ft²

a² = 41370.56 ft²

a = √(41370.56 ft²)

a = 203.4 ft

for Lisa

a'² = b'² + c'² - 2a'b'cosФ' where b = 120 ft, c = 100 ft and Ф = 148°

Thus,

a'² = (120 ft)² + (100 ft)² - 2(120 ft)(100 ft)cos148°

a'² = 14400 ft² + 10000 ft² - 24000 ft²cos148°

a'² = 14400 ft² + 10000 ft² - 24000 ft²(-0.8481)

a'² = 24400 ft² + 20353.15 ft²

a'² = 44753.15 ft²

a' = √(44753.15 ft²)

a' = 211.56 ft

a' ≅ 211.6 ft

Since a = 203.4 ft < a' = 211.6 ft,

Jon's hiding spot is closer to the starting point.

You need to find the ratio or both x and y.

If their all equal, then it is proportional.

If it’s not equal, it isn’t proportional.

You would need to divide the numbers.

Let’s say that the top number in a table is 9 and the bottom number is 90.

You would divide 90/9 and get 10. If you divide the rest, and their all 10, then it is proportional.

You have a triangle with one 70 degree angle and one 40 degree angle. What is the measure of the other angle? A) 40 degrees B) 70 degrees C) 60 degrees D) 180 degrees

Answers

Answer:

B) 70 degrees

Step-by-step explanation:

The sum of angles in a triangle = 180 degrees

We are given 2 angles in the triangle = 70° and 40°

The measure of the third angle is

180° = 70° + 40° + 3rd Angle

3rd Angle = 180° - ( 70° + 40°)

= 180° - 110°

= 70°

The measure of the other angle is 70°
