4+2×8=20

A) 50÷5+10= 20
B) 150+3-2=48
C)50÷5+4=14
D)150÷3+14=64

So A is the correct answer.

IF Q is the midpoint of PR, find the coordinates of R if P(11,-2) and Q(4,3). Write your answer in (x,y) format.

barxatty [35]

Answer:

The coordinates of R is (-3,8)

Step-by-step explanation:

The formula for the midpoint of a line segment is;

(x,y) = (x1 + x2)/2, (y1 + y2)/2

In this case, we have (x,y) = (4,3)

and we also have (x1,y1) = (11,-2)

what we do not have is (x2,y2)

From the question, we have that;

(11 + x2)/2 = 4

11 + x2 = 2(4)

11 + x2 = 8

x2 = 8-11

x2 = -3

Also;

(-2 + y2)/2 = 3

-2 + y2 = 2(3)

-2 + y2 = 6

y2 = 6 + 2

y2 = 8

So the coordinates of R is (-3,8)

Find the value of X in that isosceles triangle shown below

ipn [44]

Answer:

sqrt(13) =x

Step-by-step explanation:

We have 2 right triangles, one on the right and one on the left

The base is 1/2 of 4 or 2 and the height is 3

We can use the Pythagorean theorem to find the hypotenuse

a^2 + b^2 = c^2

2^2 + 3^2 = x^2

4+9 = x^2

13 = x^2

Take the square root of each side

sqrt(13) =x

Find the value of X. Write your answer as a decimal.

finlep [7]

Answer:

68.5

Step-by-step explanation:

Angles DEC and DAC are right angles, so their sum is 180°. DECA is a quadrilateral, which has a sum of interior angles equal to 360°. Then angle ACE is the supplement of angle D:

∠ACE = 180° -43° = 137°

Inscribed angle ABE has half the measure of central angle ACE, so we have ...

x° = 137°/2

x = 68.5

Mom wants to make 5 lbs of the sugar syrup. How much water and how much sugar does he need to make 20% syrup?

Wittaler [7]

Answer:

Let x pound of the sugar to make 20% syrup.

As per the statement:

Mom wants to make 5 Ibs of the sugar syrup.

We have to find how much water and sugar does she need to make 20% syrup.

By definition of proportion; we have

$\frac{x}{5} = \frac{20}{100}$

Simplify:

$\frac{x}{5} = \frac{1}{5}$

Multiply both sides by 5 we get;

$x = 1$

Remaining = 5 -1 = 4 pounds of water

Therefore, 1 pounds of sugar and 4 pounds of water does she need to make 20% syrup.
