pounds as a function of its age in months.
Use function notation to represent the
statement.
When the puppy was a months old, it
weighed w pounds.

The area of the figure after dilation would be 20 square units.

Scale factor is used to compare 2 quantities, indicating by how much one quantity is greater than the other. It is denoted by K. Mathematically-

K = a/b.

If a coordinate point (x, y) is dilated by a scale factor of [k], then the coordinate point after dilation will be - (kx, ky).

Given is the 2 - D figure as shown.

Assume the length of each side as 1 units. Then after the dilation by K = 2, each side would be of 2 units. Then, the area of the figure would be -

A = 5(2 x 2) = 5 x 4 = 20 square units

Therefore, the area of the figure after dilation would be 20 square units

172.5

Step-by-step explanation:

its 172.5 because 345÷2 equals 172.5 therefore she had 172.5 dollars in her savings

Answer:

54°

Step-by-step explanation:

We know that a flat line= 180° and ∠ABC is 90° which means 2x+2x+x=90°.

Therefore, 5x=90° so x=18°

18*3=54 so your answer is 54°

3x = 54°

The correct option is (C).

An angle is a form of geometrical shape, that is constructed by joining two rays to each other at their end-points. The angle can also be represented by three letters of the shape that define the angle, with the middle letter being where the angle actually is (i.e.its vertex). Angles are generally represented by Greek letters such as θ, α, β, etc.

Given,

In the figure

∠CBA = 90°

and

∠CAB + ∠CBD = 180°

Putting the value by the given figure

90° + x + 2x + 2x = 180°

5x = 180° - 90°

5x = 90°

x = 90° / 5

x = 18°

⇒ 3x = 3 × 18°

⇒ 3x = 54°

Hence, the value of 3x = 54°

Answer:

Margin of error = E = 40

Step-by-step explanation:

Assuming 99% confidence level

Given that x = 253.9  

s.d = 63.6

n = 18

Degrees of freedom = df = n - 1 = 18 - 1 = 17

At 99% confidence level the t is, α = 1 - 99% = 1 - 0.99 = 0.01

α/2 = 0.01 / 2 = 0.005

t α/2,df = t,0.005 = = 2.680 (using student t table)

Margin of error = E = t α/2,df * (s.d/√n)

Margin of error = 2.680*63.6/√18

Margin of error = 2.680*63.6/4.242641

Margin of error = 2.680*14.99066265564303

Margin of error = 40.17

Margin of error = E = 40

Step-by-step explanation:

MULTIPLE THE 2 NUMBERS

a. The amount of money that Anthony has is £26.1.

b. The amount of money that Michelle has is £39.15.

Given the following data:

To find the amount of money each of them have:

In this exercise, we are required to translate the word problem into a mathematical (algebraic) expression and solve for the unknown variable (number):

Translating the word problem into an algebraic expression, we have;

Anthony's amount is two thirds of Michelle's amount:

[tex]A = \frac{2M}{3}[/tex]   ....equation 1

Anthony and Michelle have £65.25 between them:

[tex]A+M=65.25[/tex]   ...equation 2

Substituting eqn 2 into eqn 1, we have:

[tex]\frac{2M}{3} +M=65.25\\\\2M +3M =195.75\\\\5M = 195.75\\\\M= \frac{195.75}{5}[/tex]

M = £39.15

To find the value of A:

[tex]A = \frac{2M}{3}\\\\A = \frac{2\times39.15}{3}\\\\A = \frac{78.3}{3}[/tex]

A = £26.1

Answer:

The rule is: y = -10x+85

Step-by-step explanation:

The rule is given by:

[tex]y = mx+b[/tex]

Here m is the gradient and b is the y-intercept.

We have to take two pairs of input-output to find the rule

Let the two pairs be:

(x1,y1) = (1,75)

(x2,y2) = (2,65)

Slope is found using the formula:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Putting the values

[tex]m = \frac{65-75}{2-1}\\m = -10[/tex]

Putting the value of slope

[tex]y = -10x+b[/tex]

Putting a pair of input-output in the equation (1,75)

[tex]75 = -10(1) +b\\75 = -10+b\\b = 75+10\\b = 85[/tex]

Putting the value of b

[tex]y = -10x+85[/tex]

Hence,

The rule is: y = -10x+85

Answer:

Maria

Step-by-step explanation:

Find the ratio of powdered mix to water for each drink.

For Maria:

(2/3 cup) / (2 gallon)

= 1/3 cup per gallon

For Franco:

(1 1/4 cup) / (5 gallon)

= (5/4 cup) / (5 gallon)

= 1/4 cup per gallon

Since 1/3 is bigger than 1/4, Maria's sports drink is stronger.
