Answers

Step-by-step explanation:

o2+a2=h2

100} h^{2}=(10ft)^{2} +(17ft)^{2}

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

What is the Pythagoras theorem?

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.

Philip made $1,155 in 15 days. Let "m" represent the amount of money that Philp made each day. If Philip made the same amount of money each day, how much did he make in one day.

Answers

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

Write a polynomial function of least degree with rational coefficients so that ​P(x)0 has the given roots. x=-5, x=10

Answers

Answer:

P(x) = x² - 15x + 50

Step-by-step explanation:

We write the polynomial function P(x), given that P(x) = 0 has the given roots, x = 5 and x = 10.

Since x = 5 and x = 10 are the roots of P(x) = 0, it follows that (x - 5) and (x - 10) are factors of P(x) = 0. So, P(x) = (x -5)(x - 10) = 0

Expanding the brackets, we have

x² - 10x - 5x + 50 = 0

Simplifying, we have

x² - 15x + 50 = 0 = P(x)

Thus,

P(x) = x² - 15x + 50

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]

Boba Club: y=2x+4
Jacks Boba: y=3x

Which is cheaper if you want to buy 7 boba drinks? How much cheaper? What is the solution to the system of equation?

Answers

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?)

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

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
