DE Is A Midsegment Of AABC . Find The Value Of X .B5

Answers

Answer 1

Answer:

x = 10

Step-by-step explanation:

DE is the midsegment joining the midpoints of BC and AC respectively.

Therefore, by the property of midsegment of a triangle,

DE will be parallel and half of the measure of the third side of the triangle.

DE = [tex]\frac{1}{2}(AB)[/tex]

5 = [tex]\frac{x}{2}[/tex]

x = 10 units

0/1 Gabriel used 1/3 of a liter of milk to make 2/9 of a jug of tea. How much milk is required to fill the jug?

Answers

Answer:

1 1/2 liters of milk is required to fill the jug

Step-by-step explanation:

Gabriel used 1/3 of a liter of milk to make 2/9 of a jug of tea. How much milk is required to fill the jug?

From the above question, we know that:

2/9 jug of tea = 1/3 liter of milk

1 jug of tea = x

Cross Multiply

2/9 × x = 1 × 1/3

x = 1/3 /2/9

x = 1/3 ÷ 2/9

x = 1/3 × 9/2

x = 3/2

x= 1 1/2 liters of milk

Therefore, 1 1/2 liters of milk is required to fill the jug

What is the slope of the line that passes through the points (0,5) (2,10)

Answers

Answer:

m=5/2

Step-by-step explanation:

the equation of slope is (y2-y1)/(x2-x1)

here are the points given: (0,5), (2,10)

let's label the points:

x1=0

y1=5

x2=2

y2=10

now substitute into the equation (m is the slope)

m=(10-5)/(2-0)

subtract

m=5/2

the slope is 5/2

The graphs of the equations x2 + y2 = 4 and y = 2
are drawn on the same set of axes. What is the
total number of points common to both graphs?
A. 1
B. 2
C. 3
D. 4

Answers

Im pretty sure the answer is D

The common points to both the graphs is required.

The number of points common to both graphs is A. 1

The first equation is

[tex]x^2+y^2=4[/tex]

This is a circle with its center at the origin and radius of 2 units.

The second equation is

[tex]y=2[/tex]

This is a horizontal line passing through [tex]y=2[/tex].

Let us substitute the y value in the first equation

[tex]x^2+2^2=4\\\Rightarrow x^2=0\\\Rightarrow x=0[/tex]

The intersection point is [tex](0,2)[/tex].

There is only one common point.
