Answer:

Step-by-step explanation:

As x and y are perpendicular - we can use pythagoras.

So, The length of side x squared + The length of side y squared = The missing length squared.

12^2=144

5^2=25

144+25=169

sqrt169=13

Answer:

Unknown side = 13 in

Step-by-step explanation:

If it is a right sided triangle, then you can use the Pythagoras theoreum.

unknown side = u

x² + y² = u²

12² + 5² = u²

u² = 144 + 25

u² = 169

u = + - SQRT(169)

{Only the positive value has a meaning}.

Unknown side = 13 in

U = {a, b, c, d, e, f, g, h}, A= {a, b, c, d, e) and B= {c, d, e, f, g),

now,

A-B = {a,b}

A n B = { c,d,e}

Mrs. Reyes asked 3 girls and 4 boys to help with a project. She had each student make 8 paper airplanes.

Mazyrski [523]

There are 3 girls & 4 boys.

Each student makes 8 paper airplanes.

Amount of paper airplanes created by girls: 3 x 8 = 24

Amount of paper airplanes created by boys: 4 x 8 = 32

Amount of paper airplanes created in all: 3(8) + 4(8) = 24 + 32 = 56

Anyone down to help? 12pts for PRE-ALGEBRA question Use the information in the table for 2–4.

Anni [7]

Answer:

See attached image

Step-by-step explanation:

If the number of blueberries is the x value, and number of calories is the y value, then we can create the ordered pairs (5,4) (10,8) (15,12) based on the data in the table.

Plotting these on the graph is simple - just go to the x value then the y value and plot where these lines meet.

The slope of a line is always the rise over run.

Every time our x increases by 5, our y increases by 4. The rise is 4, and run is 5, so the slope is $\frac{4}{5}$

Hope this helped!
