Answer:

24%

Step-by-step explanation:

1) 25-19=6

2) 6/25 x 100 = 24%

Answer:

x = -25

Step-by-step explanation:

Step 1: Write out equation

2/5x + 10 = 0

Step 2: Subtract 10 on both sides

2/5x + 10 - 10 = 0 - 10

2/5x = -10

Step 3: Multiply both sides by 5/2

5/2(2/5x) = -10(5/2)

x = -50/2

x = -25

Answer: 6

Step-by-step explanation:

The factors of 6 are 1, 2, and 3.

1 + 2 + 3 = 6

Answer:

y = 8x - 6

Step-by-step explanation:

find the common difference (+ or -) / ratio (x or ÷)

34 - 26 = 8

42 - 34 = 8

50 - 42 = 8

58 - 50 = 8

the common difference is 8

y = 8x + b

plug in an (x, y) value to find b

(7, 500

50 = 8(7) + b

50 = 56 + b

b = -6

y = 8x - 6

Answer:

height = 2m at t = 0s

height = 22.1m at t = 1s

height = 32.4m at t = 2s

height = 32.9m at t = 3s

height = 23.6m at t = 4s

height = 4.5m at t = 5s

Step-by-step explanation:

Given equation:

H(t) = -4.9t² + 25t + 2           ----------------(i)

The height of the ball is a function of time. Therefore;

(i) At the 0th second. i.e t = 0, we get the height by substituting the value of t = 0 into equation (i). i.e

H(0) = -4.9(0)² + 25(0) + 2

H(0) = 2

∴ At t = 0, the height is 2 meters. This is also obvious in the first statement of the question.

(ii) 1st second. i.e t = 1, we get the height by substituting the value of t = 1 into equation (i). i.e

H(1) = -4.9(1)² + 25(1) + 2

H(1) = 22.1

∴ At t = 1, the height is 22.1 meters.

(iii) 2nd second. i.e t = 2, we get the height by substituting the value of t = 2 into equation (i). i.e

H(2) = -4.9(2)² + 25(2) + 2

H(2) = 32.4

∴ At t = 2, the height is 32.4 meters.

(iv) 3rd second. i.e t = 3, we get the height by substituting the value of t = 3 into equation (i). i.e

H(3) = -4.9(3)² + 25(3) + 2

H(3) = 32.9

∴ At t = 3, the height is 32.9 meters.

(v) 4th second. i.e t = 4, we get the height by substituting the value of t = 4 into equation (i). i.e

H(4) = -4.9(4)² + 25(4) + 2

H(4) = 23.6

∴ At t = 4, the height is 23.6 meters.

(vi) 5th second. i.e t = 5, we get the height by substituting the value of t = 5 into equation (i). i.e

H(5) = -4.9(5)² + 25(5) + 2

H(5) = 4.5

∴ At t = 5, the height is 4.5 meters.

Answer:

2, -2

Step-by-step explanation:

f(x) = 2x + 1

g(x) = x - 3

To find g(f(x)), you need to put f(x) into g(x).

g(f(x)) = (2x + 1) - 3

g(f(x)) = 2x + 1 - 3

g(f(x)) = 2x - 2

Your answer will be 2 and -2.

Answer:

a=8

Step-by-step explanation:

-280=-7(6a-8)

Distribute

-280=-7*6a-7+-8

-280=-42a+56

Subtract 56 from both sides

-336=-42a

Divide both sides by -42.

a=8

Answer:

 (x - 8)^2 + y^2 = 3.

Step-by-step explanation:

(x - h)^2 + (y - k)^2 = r^2

Here h = 8, k = 0 and r^2 = (√3)^2 = 3

The answer is  (x - 8)^2 + (y - 0)^2 = 3

or (x - 8)^2 + y^2 = 3.

Answer: The inverse relation is { (-1, -8), (-1, -8), (-8, -2), (8, 2) }

The inverse is effectively the opposite of the original relation. It undoes what the original relation does. So we'll swap the x and y values for each given point in the form (x,y). Something like (8,-1) becomes (-1,8). The other points follow the same pattern as well.

Answer:

He will have 334 Euros

Step-by-step explanation:

Hello.

Here is a currency conversion problem.

The man in this question seeks to convert his Canadian dollars to Euro as he is in France for a trip.

The exchange rate is given as;

1.28 canadian dollar = 1 euro

He has 427 CAD , and we want to know the amount in euro.

let the equivalent amount in Euro be x

Thus;

if

1.28 CAD = 1 EUR

427 CAD = X EUR

By cross multiplying, we have

1.28 * x = 427 * 1

x = 427/1.28

x = 333.59 Euros which is approximately 334 Euros

Answer:

12,500= £25

Step-by-step explanation:

Because every 1000 it makes £2 from ad venue, we must: (we can do two methods)

1.Divide £25 by £2 then multiply it by 1000. By doing this, we will know how many times 1000 are made when there is £25.

1000= £2

? = £25

So:

£25 ÷ £2= 12.5

12.5 × 1000= 12,500

2. Find how much it made for £1 by dividing 1000 by £2, then multiplying it by £25.

So:

1000 ÷ £2= 500

500 × £25= 12,500

Answer:

[tex]n=-4[/tex]

Step-by-step explanation:

So we have the equation:

[tex]2+4(2-3n)=58[/tex]

First, distribute the second term:

[tex]2+4(2)-4(3n)=58\\2+8-12n=58[/tex]

Add the left side:

[tex]10-12n=58[/tex]

Subtract both sides by 10. The left side cancels:

[tex](10-12n)-10=(58)-10\\-12n=48[/tex]

Divide both sides by -12. The left side cancels:

[tex](-12n)/-12=(48)/-12\\n=-4[/tex]

Therefore, the value of n is -4.

⇒2 + 4(2 - 3n) = 58

⇒4(2 - 3n) = 58 - 2

⇒2*4 - 3n*4 = 56

⇒8 - 12n = 56

⇒-12n = 56 - 8

⇒-12n = 48

⇒-n = 48/12

⇒-n = 4

⇒n = - 4

Hence, value of n is - 4

The required solutions are,

1. operations.
2. w(xy)z.
3. w(xy)z

The associative property is a mathematical principle that states that the grouping of operations or factors does not affect the final result of a calculation, as long as the order of the terms remains the same.

Here,
The associative property allows us to change the grouping of the factors that are multiplied together to create 2. operations.

When changing the grouping, the order of the factors stays the same; only the position changes.

The expression 3. (wx)yz is an equivalent expression to w(xy)z.

The expression 2. wx(yz) is also an equivalent expression to w(xy)z.

Answer:

m+13/-2 = n (m plus 13, divided by negative 2 equals n)

Step-by-step explanation:

m+1 = -2(n+6)

distribute -2

m+1 = -2n-12

add 12 to both sides

m+1 = -2n-12

+12 +12

with that you get

Answer:

(16.2t+3.4u+2.9)cm

Step-by-step explanation:

A triangle is a plane shape that has three sides. The perimeter of a triangle is gotten by taking the sum of all the lengths of the three sides. Let the length of the three sides by s1, s2 and s3, the perimeter of the triangle will be expressed as;

P = s1+s2+s3

Given the side lengths

s1 = (8.1t-6.1)cm

s2 = (8.1t+7.1)cm

s3 = (3.4u+1.9)cm

Perimeter of the triangle = 8.1t-6.1+8.1t+7.1+3.4u+1.9

collect the like terms

P = 8.1t+8.1t+3.4u-6.1+7.1+1.9

P = 16.2t+3.4u+2.9

Hence the expression that represents the perimeter, in centimeters, of the triangle is  (16.2t+3.4u+2.9)cm

Answer:

Greatest prime factor of [tex]nt[/tex] is 7.

Step-by-step explanation:

Given that

Two positive integers are [tex]n[/tex] and [tex]t[/tex].

(1) Greatest Common Factor or HCF of [tex]n[/tex] and [tex]t[/tex] is 5.

(2) Least Common Multiple or LCM of [tex]n[/tex] and [tex]t[/tex] is 105.

To find:

The greatest prime factor of the product [tex]nt[/tex] = ?

Solution:

First of all, let us learn about a property of HCF and LCM of two numbers.

The product of two numbers [tex]p[/tex] and [tex]q[/tex] is equal to the product of their HCF and LCM.

[tex]p \times q =LCM\times HCF[/tex]

Using this property for the given numbers:

[tex]n\times t =5\times 105\\OR\\nt =5\times105[/tex]

Now, let us make prime factors of [tex]5 \times 105[/tex] to find the greatest of the prime factors.

[tex]5\times 105 = 5\times 5 \times 21 =5\times 5 \times 3 \times \bold{7}[/tex]

So, the prime factors of [tex]5 \times 105[/tex] are 5, 5, 3 and 7.

Greatest prime factor of [tex]nt[/tex] is 7.

Answer:

54kg

Step-by-step explanation:

Body weight = B

Tail weight = T

Head weight = H

Total weight = F

Use equation = B + T + H = F

We are told that T = 9kg, H = T + (1/3) x B, B = H + T

We have 3 equations and 3 unknowns, solve the system of equations to find W.  

B = H + 9

H = 9 + 1/3 x (H+9)=9+H/3+3 --> 2/3 x H = 12  --> H = 18

B = 18 + 9 = 27

F = 18 + 27 + 9 = 54kg
