Answer:

B' has a coordinate pair of (-4, -1)

Step-by-step explanation:

We are given with the vertices of the triangle with B(-8,-2)

Please remember the rule of dilation

If a point (x,y) dilated for the scale factor of 'k', we do get image as (kx,ky)

Using this concept, we know scale factor is [tex]\frac{1}{2}[/tex] , we could get image as [tex](\frac{1}{2} (-8), \frac{1}{2} (-2))[/tex]

Let's simplify it

We do get (-4,-1)

Answer:

$15.27

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let the number of ounces of

A = x

B = y

A scientist has two solutions, which she has labeled Solution A and Solution Each contains salt. She knows that Solution A is 40% salt and Solution B is 55% salt. She wants to obtain 90 ounces of a mixture that is 45% salt. How many ounces of each solution should she use?

Our system of equations is given as

x + y = 90.... Equation 1

x = 90 - y

40% × x + 55% × y = 45% × 90 ounces

0.4x + 0.55y = 40.5....Equation 2

We substitute 90 - y for x in Equation 2

Answer:

he made in one day is $77

Step-by-step explanation:

Given that

Philip made $1,155 in 15 days

Now based on the above information

The amount he make in one day is shown below:

= $1,155 ÷ 15 days

= $77

hence he made in one day is $77

The same would be relevant

Answer:

7.5 years.

Step-by-step explanation:

Use A = 1400(1+0.02)^7.5

The 1400 is the starting money. The 1 is a constant. The 0.02 is the 2% in decimal form. And the 7.5 is years. I found that by just continually increasing it until it hit 1624.

Hope this helps

Answer:

n = 12

Step-by-step explanation:

By applying geometric mean theorem in the given right angle triangle,

[tex]\frac{AD}{BD}=\frac{BD}{DC}[/tex]

BD² = AD × DC

Now substitute the values of each side given,

n² = 6 × 24

n² = 144

n = 12

Answer:1/2 - 1/3 = 1/6

Step-by-step explanation:

Answer: 1/6 or 0.16

Step-by-step explanation: hope this helps!

Step-by-step explanation:

2/3=4/6

1/2=3/6

3/6+4/6=7/6

2-1 1/6= 5/6

so the answer is 5/6 the decimal form is .83333333.......

Answer:

x = 30

Step-by-step explanation:

If   X - 9 = 21,   then 21 + 9 = X.

21 + 9 = 30  

Answer:

x=30 (think about the opposite way to do it, 21+9)

Step-by-step explanation:

30-9=21 soo yea

this is an example on how to do it

The value of g in the given right triangle is 13.20 units.

Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse.

Given that, a right triangle with leg lengths f and g, and hypotenuse h, if f = 7 cm and h = 11.2 cm,

We need to find the value of g the hypotenuse,

So, here using the Pythagoras theorem,

f²+h² = g²

Therefore,

11.2²+7² = g²

g² = 174.44

g = 13.20

Hence, the value of g in the given right triangle is 13.20 units.

Answer:

Boba Club is cheaper if you want to buy 7 Boba drinks. It's cheaper by 3.

Step-by-step explanation:

Boba Club: y=2x+4

Jack's Boba: y=3x

Replace the X variable with 7 for both equations. For Boba Club, multiply 2 by seven to get 14, then add four to get 18. For Jack's Boba, multiply 3 and 7 to get 21. Boba Club is cheaper. (What would you need 7 Boba drinks for though?)

Answer:

y=1/4x + 3

Step-by-step explanation:

We know that the beginning of the equation has to be 1/4x since the line has to be parallel. So what I did was start at -4,2 then go up 1 and over 4, which led me to 3 as the y intercept.
