Ruth, Daisy, and Martin share £750 in the ratio of 3:5:7. Determine how much money Ruth receives.

Answers

Answer 1

Answer:

Answer:

Ruth receives £150

Step-by-step explanation:

sum the parts of the ratio, 3 + 5 + 7 = 15 parts

divide the total £750 by 15 to find the value of one part of the ratio

£750 ÷ 15 = £50 ← value of 1 part of the ratio

Then

3 parts = 3 × £50 = £150 ← amount Ruth receives

Cassie is a half pound of sugar in her cabinet her cake recipe calls for two tenths of a pound of sugar how many cakes can she make

Answers

The information's given in the question should be very minutely checked. Based on those given information's the answer to the question can easily be deduced.
Amount of sugar in the cabinet of Cassie = 1/2 pound
Amount of sugar required by Cassie to make her cake recipe = 2/10 pound
   = 1/5 pounds
Then
The number of cakes that Cassie can make = (1/2)/(1/5)
      = 5/2
      = 2 1/2
So from the above deduction we can easily conclude that Cassie can make a total of 2 cakes with the sugar she has and there will still be some sugar left.

Answer:2cakes

Which of the following shows the correct factorization of x3 - 5x2 - 14x?A. x(x + 7)(x + 2)

B. x(x - 7)(x - 2)

C. x(x + 7)(x - 2)

D. x(x - 7)(x + 2)

Answers

So, just a note of formatting, to indicate something is an exponent of something else, use the carat (^) sign
for instance
x^3 means x cubed. x3 means 3x.
Anyways, though, let's factor.
You can factor out an x from each variable.
x(x^2-5x-14)
Now, to factor this, think of what will add to -5, and multiply to -14.
-7 and 2 work.
So, this factors out to
x(x-7)(x+2)
Choice D is the correct factorization.

Y is 15 and x is 14 mark me as brainless

x = 13, assuming they are the same length.
Using the pythagorean Theorem formula (a^2 + b^2 + c^2) Plug in A and B (13, and 13).
(13)^2 + (13)^2 = c^2
13 • 13 + 13 • 13 = c^2
169 + 169 = c^2
v/338 = v/c^2 (square root them both)
Then you can have your answer for y, hope this helps
