Answer:

Volume of sphere = 130.9cm³

Step-by-step explanation:

Formula :

[tex] \frac{4}{3} \times \pi \: \times r^{3} [/tex]

We need the radius. 6.3 ÷2=3.15

[tex] \frac{4}{3} \times \pi \times 3.15 ^{3} [/tex]

=130.924303cm³

rounded to the nearest tenth

=130.9cm³

Answer:

Option B (the pentagonal pyramid)

Step-by-step explanation:

Given the pentagram, we can see a pentagon in the middle. The pentagonal prism (option A) and pentagonal pyramid (option B) both have bases of a pentagon. However, their nets are different. Only the pentagonal pyramid's net is that of a pentagram. Therefore, option B is correct.

Answer:

x = 46°

Step-by-step explanation:

Since Δ ABC is equilateral then interior angles = 60°

Since CE = DE then Δ CDE is isosceles and the base angles are congruent, so

∠ ECD = [tex]\frac{180-32}{2}[/tex] = [tex]\frac{148}{2}[/tex] = 74°

BCD is a straight line, then the 3 angles on it sum to 180°, that is

60° + 74° + x = 180°

134° + x = 180° ( subtract 134° from both sides )

x = 46°

Answer:

18

Step-by-step explanation:

Just go in the order as is. You add the 3 numbers together, 8+4=12+10=22, then subtract off 4, 22-4=18.

Answer:

18

Step-by-step explanation:

break it down!

8 + 4 = 12

12 + 10 = 22

22 - 4 = 18

Answer:

6 bags of snack mix

Step-by-step explanation:

x bags of snack mix

y bottles of water

The equations in the question is given as;

20.00 = 2.50x + 1.00y  (i)

11 = x + y (ii)

From eqn (ii);

11 - y = x

substitute the value of x in eqn (i);

20.00 = 2.50(11 - y) + 1.00y

20.00 = 27.5 - 2.50y + 1.00y

20.00  - 27.5  = - 1.50 y

- 7.5 = - 1.50 y

y = - 7.5 / (- 1.5) = 5

Since we are interested in the value of x. Substitute the value of y in eqn (ii);

11 = x + 5

x = 11 - 5 = 6

Answer:

[tex] - 6y + 12 = - 66 \\ - 6y = - 66 - 12 \\ - 6y = - 78 \\ y = - \frac{ - 78}{ - 6} \\ y = 13[/tex]

Answer:

y = 13

Answer:

43.2

Step-by-step explanation:

first turn 2 1/2 into an improper fraction

(2 × 2) + 1 = 5

5/2

then turn 5/2 into a fraction

5 ÷ 2 = 2.5

now divide!

108 ÷ 2.5 = 43.2

Number equivalent to 108/2 1/2 is 43.2 .

Given,

108 divided 2 1/2

Using division property,

The rules for division are:

(1) positive × or ÷ positive = positive

(2) positive × or ÷ negative = negative

(3) negative × or ÷ negative = positive

Rule for long division method,

Divide the tens column dividend by the divisor.

Multiply the divisor by the quotient in the tens place column.

Subtract the product from the divisor.

Bring down the dividend in the ones column and repeat.

Therefore,

divide, multiply, subtract, bring down and repeat or find the remainder.

Here the required value is of :

108/2 1/2

= 108 / (5/2)

= 43.2

Hence the answer is 43.2

Answer:

74.6

Step-by-step explanation:

The area of the given triangle in the image is 74.8m².

A triangle is simply a polygon with three vertices with three edges.

A scalene triangle is the triangle with no equal sides and angles.

It area can be calculated using the expression;

A = 1/2 × absinθ

Given the data in question;

To determine the area of the triangle, we substitute our given values into the expression above.

A = 1/2 × absinθ

A = 1/2 × 15m × 11m × sin( 115° )

A = 0.5 × 15m × 11m × 0.9063

A = 74.76975m²

A = 74.8m²

Therefore, the area of the given triangle in the image is 74.8m²

Answer:

The Y-intercept is 4 or (0,4) in a plot

Step-by-step explanation:

To find the Y-intercept you need to make the "x" zero so if you move 5 to 4 in the "x" plot you need to move 16 to 13

(Since 22 to 19 is -3 19 to 16 is -3 as well it is safe to say that the next number is 13)

Now continue until you reach 0 in the "x"

4 to 3 and 13 to 10

3 to 2 and 10 to 7

2 to 1 and 7 to 4

So the y-intercept is 4 or (0,4) in a plot

Answer:

68°

Step-by-step explanation:

We can find this by remembering that tangents meet a circle at a ninety degree angle with the diameter or a radius that touches the point of intersection. By understanding that because these two tangents intersect at a point outside the circle there angle measure is the same so we can use the 180° total in a triangle to find the remaining degrees to be divided into the two measures we need to find. Because 180 - 48 equals 132 we divide this by 2 to get our angle measure of 68 degrees.
