Answer:

96

Step-by-step explanation:

180 - 31 - 53 = 96

Answer:

96 should be the right answer.

Step-by-step explanation:

straight line means 180 degrees. so:

53 + 31 + x = 180

84 + x = 180

make x the subject:

x = 180 - 84

= 96

Answer:

vertex is (2 , -21)

x = -2 +√10

y = (x-3)²+1

Step-by-step explanation:

x² - 4x - 17

(x² - 4x + 4) - 4 - 17

(x-2)² - 21

vertex is (2 , -21)

2x² +8x = 12

x² + 4x = 6

(x² +4x + 4) - 6 - 4

(x+2)²  - 10

x+2 = √10

x = -2 +√10

y = (x-3)²+1

Answer:

D

Step-by-step explanation:

If you're trying to say find f(x) = 5ˣ when x = -3

The answer would be [tex]\frac{1}{125}[/tex]

A negative exponent means to put that value in the reciprocal. So the reciprocal of 5 is [tex]\frac{1}{5}[/tex]  . and the 3 means to multiply it 3 times like [tex](\frac{1}{5})(\frac{1}{5})(\frac{1}{5})[/tex] to get [tex]\frac{1}{125}[/tex]

Answer: Rs 1469

Step-by-step explanation:

Coat of item = RS 1300

Value added tax = 13%

The price of the item will then be calculated as:

= 1300 + (1300 × 13%)

= 1300 + (1300 × 0.13)

= 1300 + 169

= Rs 1469

Answer: B and C

Step-by-step explanation: To start off, you subtract 3 from both sides, to get 4<z/2, then multiply both sides by 2, you get z>8. Now it's greater than 8, so it can't equal 8, so the answers would be B and C, since they are both greater than 8, and you have to select multiple choices.

Answer:

As

[tex]p(-5) = 0[/tex]

Thus, the correct option is 'd'.

Step-by-step explanation:

We know that the special theorem of remainder states that:

if

[tex]x-k[/tex] is a factor of [tex]p(x)[/tex]

then

[tex]p(k) = 0[/tex]

so

[tex]x+5 = x-(-5)[/tex]

[tex]k = -5[/tex]

Thus,

[tex]p(k) = 0[/tex]

[tex]p(-5) = 0[/tex]

Thus, the correct option is 'd'.

Step-by-step explanation:

The radius of the circle is 4 units

The equation of the circle is given as:

(x + 5)^2 + (y - 3)^2 = 4^2

The general equation of a circle is given as:

(x - a)^2 + (y - b)^2 = r^2

Where r represents the radius

By comparing both equations, we have:

r^2 = 4^2

Take the square root of both sides

r = 4

Hence, the radius of the circle is 4 units

The circumference of the larger circle is 2 times the circumference of the original circle.

Let r be the radius of the circle.

Then the area of the circle will be

A = πr² square units

The circumference of the circle will be

C = 2πr units

If the diameter of a circle doubles, the circumference of the larger circle.

Let d be the diameter of the circle.

Then the diameter of the small circle is d and the diameter of the other circle is 2d.

Then the ratio of the circumference of the circles will be

⇒ 2πr₂ / 2πr₁

⇒ 2r₂ / 2r₁

⇒ 2d / d

⇒ 2

The circumference of the larger circle is 2 times the circumference of the original circle.

The least number of cabins needed for campers is 8.

Given that, Shady Rivers summer camp has 188 campers this week.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

The least number of cabins needed = Total number of campers/Number of campers to each cabin

= 188/22

= 8.54

Therefore, the least number of cabins needed for campers is 8.
