Answer:

11 inches

Step-by-step explanation:

We know that [tex]SA=4\pi r^2[/tex]. We know that [tex]SA=379.94[/tex] and that [tex]\pi\approx3.14[/tex]. We solve for [tex]r[/tex]: [tex]379.97=4\times3.14\times r^2[/tex]

[tex]r^2=30.25[/tex]

[tex]r=5.5[/tex]

Since [tex]d=2r[/tex], the diameter of the sphere is 11 inches.

Answer:

Obtuse Triangle.

Step-by-step explanation:

An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. In this case, 110° is more than 90°. So, its an obtuse angle. If one angle of the triangle is obtuse, then the other two angles with always be acute.

Hence, this is an obtuse triangle

The triangle with the given measures is obtuse angle triangle. Therefore, option B is the correct answer.

An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. In an obtuse triangle, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°.

Given that, a triangle has three angles of 36°, 34°, and 110°.

Here, one of the angle measure more than 90°, that is 110°.

Sum of remaining two angles is 36°+34°

= 70°

Therefore, option B is the correct answer.

hope it helps.

Answer:

52 cm (second opinion)

Step-by-step explanation:

add all the sides

Answer: V = The square root of (2K/M)

We are starting with the formula: K = 0.5MV^2

Our first steps to isolate V would be to multiply by 2 and divide by M on both sides of the equation.

2K/M = V^2

Now, we just have to take the square root of both sides of the equation

The equation rearranged for m is [tex]m = (2K) / v^2[/tex].

This equation allows us to calculate the mass (m) when the kinetic energy (K) and the velocity (v) are known.

To rearrange the equation [tex]K = (1/2)mv^2[/tex] for m, we can follow these steps:

Step 1: Multiply both sides of the equation by 2 to remove the fraction:

[tex]2K = mv^2[/tex]

Step 2: Divide both sides of the equation by[tex]v^2[/tex] to isolate m:

[tex](2K) / v^2 = m[/tex]

Therefore, the equation rearranged for m is [tex]m = (2K) / v^2[/tex].

This equation allows us to calculate the mass (m) when the kinetic energy (K) and the velocity (v) are known.

Explanation:

A good way to find the area of a figure with diagonal lines is to find the area of the section that has full squares and then add the other parts together and find the area of that. As you can see in the polygon, there are four units in the middle that don't get cut off by the diagonal line. The area of that part of the figure is 1*4 = 4. Now, if you take out that section, and move the other parts together, you can find their area and then add it to 4. The other parts of the polygons are triangles, and when you move them together, they form the same shape as the middle section did, and have an area of 4. The area of the entire figure is the area of one section plus the area of the other. 4 + 4 = 8

Answer:The answer is z

Step-by-step explanation:

Answer: Store A: 7,000 Store B: 20,000

Step-by-step explanation:

The amount of shrinkage for store A is $7000 and for store B is $20000.

"If the selling price of an item is less than the cost price, then the difference between the cost price and the selling price of an item is called the loss".

For the given situation,

The merchandise book value for store A = $757,000

The merchandise book value for store B = $600,000

Based on physical inventory reports,

The merchandise value for store A = $750,000

The merchandise value for store B = $580,000.

The amount of shrinkage determines the loss and it is calculated by taking the difference between the values.

Store A = [tex]757000-750000[/tex]

⇒ [tex]7000[/tex]

Sore B = [tex]600,000-580000[/tex]

⇒ [tex]20000[/tex]

Hence we can conclude that the amount of shrinkage for store A is $7000 and for store B is $20000.

Step-by-step explanation:

these angles will add to 90 deg

90 = 22 + 2x

solve for x

Answer:

x = 34°

2x = 68°

Step-by-step explanation:

Both angles are complementary (add up to the sum of 90°), so we can say;

22 + 2x = 90°

2x = 90 - 22

2x = 68

x = 68 / 2

x = 34°

Furthermore:

If you have to find the value of 2x it would be 68, since

2x = 2(34) = 68°
