Answer:

B. 72.5

Step-by-step explanation:

b° = 1/2(180° - 35°)

b° = 1/2 * 145°

b° = 72.5°

b = 72.5

The value of angle b will be 72.5°. Then the correct option is B.

It is the center of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

The angle that the very same arc subtends at any point around the circle's periphery is the double of the angle that same arc subtends at the center.

The central angle is 35°. Then the angle at the periphery will be

⇒ 35 / 2

⇒ 17.5°

We know that the radius of the circle and tangent of the circle makes 90°.

Then the angle b is given as

b + 17.5 + 90 = 180

                  b = 180 – 107.5

                  b = 72.5°

Thus, the value of angle b will be 72.5°.

Then the correct option is B.

Answer:

Step-by-step explanation:

Clear question is;

A ball is dropped from the top of a

building. The expression 4.9x² gives the distance in meters the ball

has fallen after x seconds. Write and simplify an expression that gives the

distance in meters the ball has fallen after x² seconds. after x³ seconds.

Answer:

A) Distance = 4.9x⁴

B) Distance = 4.9x^(6)

Step-by-step explanation:

We are given the expression 4.9x² which is the distance in meters the ball

has fallen after x seconds.

Thus,

A) after x² seconds, we have;

Distance = 4.9(x²)²

Distance = 4.9 * (x²) * (x²)

When we have to multiply 2 same numbers with the same power, the powers add up. Thus, we now have;

Distance = 4.9x⁴

B) after x³ seconds, we have;

Distance = 4.9(x³)²

Distance = 4.9 * (x³) * (x³)

When we have to multiply 2 same numbers with the same power, the powers add up. Thus, we now have;

Distance = 4.9x^(6)

1. (1 / 5)5 * 14 = 14 because 1/5 multplied by 5 is equal to 1. I believe this is called reciprocals.

2. 6 + 4 (19 - 5) = 6 + 4(19) - 4(5) = 6 + 76 - 20 = 62. This is called the distributive property.

3. 5 (14 - 5) + 6 (3 + 7) = 5(14) - 5(5) + 6(3) + 6(7) = 70 - 25 + 18 + 42 = 105. We also used the distributive property in this question.

Answer:

q = 6/13, p = 35/13

Step-by-step explanation:

3p + 2q = 9

2p - 3q = 4

_________ (subtract the two equation from each other.)

p + 5q = 5

p = 5 - 5q

2(5 - 5q) - 3q = 4 (substitute value of p into equation)

10 - 10q - 3q = 4

10 - 13q = 4

-13q = -6

q = 6/13

3p + 2(6/13) = 9 (substitute value of q into equation)

3p + 12/13 = 9

3p = 105/13

p = 35/13

Correct question:

The LCM of two numbers is 9 times their HCF .The sum of LCM and HCF is 500 . Find the HCF​  of two numbers.​

Answer:

The HCF of two numbers is 50.

Step-by-step explanation:

let the H.C.F of the two numbers = x

let the L.C.M of the two numbers = y

y = 9x -------equation (1)

y + x = 500 -------- equation (2)

y = 500 - x

Substitute in the value of y in equation (1)

500 - x = 9x

500 = 9x + x

500 = 10x

x = 500 / 10

x = 50

Therefore, the HCF of two numbers is 50.

Answer:

50

Step-by-step explanation:

There are 2 prime factors that are different and 2 numbers that we look for that are identical when looking for prime factors.

So  for numbers that don't end in 0 like 500 we can start with 3 to get 27 as one of the two numbers, then we look to see if 27 divides into that.

But for 500 it will always be numbers that end in  0 or 5  and also 1,  2 and 4

So we work with 9+1 = 10

x = 10

500/10 = 50

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x - 3)² + (y + 4)² = 36 ← is in standard form

with (h, k) = (3, - 4 ) = centre and r = [tex]\sqrt{36}[/tex] = 6

Susan interpreted the values of h and k incorrectly by using the values - 3 and 4 instead of taking the negative of them.

She also divided 36 by 2 , thus omitting the root of 36

Answer:

Option A

Step-by-step explanation:

The expression that completes the blank is A. 11  x  w * x 3 = 11  x 3  x  w.

The commutative property is a mathematical concept that states that the order in which we multiply the factors does not affect the product.

According to the commutative property, a mathematical principle, the product is unaffected by the order in which we multiply the integers.

According to the above, the example of a commutative property is:

11  x w x 3 = 11 x  3 x w

This expression is the one with the commutative property because it has the same factors on both sides of the equation in a different order and that does not affect the result.

Therefore, the correct answer is A.

This question is incomplete because you are missing the options, here are the options:

A. 11 x w x 3 = 11 x 3 x w

B. 11 x w x 3 = 11 x w x 3

C. (11 x w) x 3 = 11 x (w x 3)

D. 11 x (w x 3) = (11 x w) + (11 x 3)

Step-by-step explanation:

Let's say x represent the the total amount of money in her savings account.So if 5 and 6 dollars we deducted will have the expression

x - 5 -6       or x -11  

In this case Janet deducted 11 dollars.

Answer:

y = 15, 11, and -1 when x = -1, 0, and 3 (respectively).  Together, we have the points (-1, 15), (0, 11), and (3, -1).

Step-by-step explanation:

Assuming you want to find the values of y for each evaluated x, we will simply plug in the values into the equation.

y + 4x = 11

y = 11 - 4x

For x = -1

y = 11 - 4(-1)

y = 15

For x = 0

y = 11 - 4(0)

y = 11

For x = 3

y = 11 - 4(3)

y = -1

Thus, we have the points, (-1, 15), (0, 11), and (3, -1).

43. To find total sales for the week, multiply the price of a tin of popcorn by the number sold in the week (42).

Answer:

41) 0.25 × 0.4 = 0.1

It has only one decimal place in the product because 0.25 has two significant figures and 0.4 has one significant figure. When multiplying, the product will always match with the number that has the least amount of significant figures. Since 0.4 has one significant figure, the product, 0.1, will also have one significant figure.

42) 35.5 s × 52 times/s = 1,846 times

43) 42 tins × $9.25/tin = $388.50

Answer:

The million dollar cube will be 10.79 cm tall

Step-by-step explanation:

Let the sides of the gold cube representing the tallness of the cube  be s

volume of the gold cube V = s³

Then :

[tex]\mathbf{s = \sqrt[3]{V} }[/tex]  --- (1)

Similarly; we know that , density ρ = mass m/Volume V

making volume the subject of the formula, then ;

V = m/ρ

Replacing that into (1) above , we have:

[tex]\mathbf{s = \sqrt[3]{\dfrac{m}{\rho}} }[/tex]

Given that:

At the time, gold is selling for $1282 per troy ounce

∴ In a million-dollar cube of gold, the number of troy ounce that can be bought with a million dollar = 1000000/1282 = 780.03 troy ounce

Since 1.0000 troy ounce equals 31.1035 g

∴ 780.03 troy ounce = 780.03  × 31.1035 g

= 24261.66 g

From the tables 12.1 of Gold , the density of Gold is obtained as 19.3 g/cm³

∴

[tex]\mathbf{s = \sqrt[3]{\dfrac{m}{\rho}} }[/tex]

[tex]\mathbf{s = \sqrt[3]{\dfrac{24261.66}{19.3}} }[/tex]

[tex]\mathbf{s = \sqrt[3]{1257.080829} }[/tex]

[tex]\mathbf{s = 10.79 \ cm }}[/tex]

The million dollar cube will be 10.79 cm tall

Answer:

Step-by-step explanation:

Given  P(0,-3), Q(7,0), to get PQ, we will use the formula fr calculating the distance between two points expressed as;

PQ = √(x₂-x₁)²+(y₂-y₁)²

From the given coordinates, x₁ = 0, y₁ = -3, x₂ = 7, y₂ = 0

PQ = √(7-0)²+(0-(-3))²

PQ = √7²+3²

PQ = √49+9

PQ = √58

Let the coordinte of the midpoint be (X, Y)

X = x₁+x₂/2 and Y = y₁+y₂/2

Substituting the given coordinates will give;

X = 0+7/2

X = 7/2

X = 3.5

Y = -3+0/2

Y = -3/2

Y = -1.5

Hence, the coordinates of the midpoint of PQ is (3.5, -1.5)
