PilotLPTM [1.2K]3 years ago
5 0

Answer:

2/3 cup

Step-by-step explanation:

first you need to convert the fractions so that they have the same denominator (1/3 turns into 2/6)

then you just add up the numerators (2+2=4..... 4/6)

you can stop there or you can simplify it (4/6 turns into 2/3)

A positive real number is 5 more than another. When - 10 times the smaller is added to the square of the larger, the result is 5
salantis [7]

Answer:

4√2 and 5+4√2

Step-by-step explanation:

Let the two numbers be x ad y

Smaller = y

Bigger = x

If a positive real number is 5 more than another, then;

x = 5 + y ... 1

When - 10 times the smaller is added to the square of the larger, the result is 57, then;

-10y + x² = 57 ...2

Substitute 1 into 2;

-10y + (5+y)² = 57

-10y + 25+10y+y² = 57  

y²+25 = 57

y² = 57 - 25

y² = 32

y = √32

y = 4√2

Since x = 5 + y

x = 5 + 4√2

Hence rhe numbers are 4√2 and 5+4√2

The equilateral triangle shown is rotated about line a. Each side of the triangle measures 20 mm. What shape is created by the r
zysi [14]

Answer:

a cone with a base circumference of about 126 mm

Step-by-step explanation:

Rotating a triangle about a line results in a cone created by the rotation.  This is because the segment at the bottom forms a circle, and the point at the top stays there; the three-dimensional figure with a circular base and a point at the top is a cone.

Since we rotate the segments about a line, this makes the length of the base the radius of the circle. This means the circumference would be

C = 2πr = 2(3.14)(20) = 125.6 ≈ 126 mm
