Answer 1

From the given figure ,

RECA is a quadrilateral

RC divides it into two parts

From the triangles , ∆REC and ∆RAC

RE = RA (Given)

angle CRE = angle CRA (Given)

RC = RC (Common side)

Therefore, ∆REC is Congruent to ∆RAC

∆REC =~ ∆RAC by SAS Property

⇛CE = CA (Congruent parts in a congruent triangles)

Hence , Proved

Additional comment:-

SAS property:-

"The two sides and included angle of one triangle are equal to the two sides and included angle then the two triangles are Congruent and this property is called SAS Property (Side -Angle-Side)

If you add the lengths of the focal radii of an ellipse, what other value will you produce?

Answers

Answer: the length of the major axis

Step-by-step found it on Quizlet and got it right on the quiz

If we add the lengths of focal radii of an ellipse the value of length of major axis will produce.

What is the major axis of an ellipse?

The major axis of an ellipse is the line segment connecting the two vertices.

Since, the sum of focal distances of a point on ellipse is constant.

And it is equals to the length of major axis.

Hence, if we add the lengths of focal radii of an ellipse the value of length of major axis will produce.

Answers

Answer:

They are proportional

Step-by-step explanation:

Proportionality:

They are proportional because the cost is going up by 10 the entire time and the hours rented is going up by 2 the entire time.

Graphing:

Go to the 2 on the x-axis (horizontal line)

Go up to the 20 on the y-axis (vertical line)

The points to graph are:

(2,20)

(4,30)

(6,40)

(8,50)

I put a pic of what your graph should look like below!

Answer:

To plot the graph put the hours along the x axis and the cost on the y axis. Its a positive realationship because when the hours go up the cost goes up to, it isn't proportional because both values don't go up at the same rate.

Mrs. Collado is buying a

Answers

9514 1404 393

Answer:

  $612.86

Step-by-step explanation:

The discount multiplies the price by (1 -10%) = 0.90.

The tax multiplies the price by (1 +6%) = 1.06

Then the total price with delivery charge is ...

  $590×0.90×1.06 +50 = $612.86

612.86

Step-by-step explanation:

10% is 59 590-59=531

Is there a value of x that makes each of the following equalities true? If there is, find it.
a. √x-3=0
b. √x=-10
c. √x+1=0
d. √x=0.1

Answers

Step-by-step explanation:

a. √x - 3 = 0 ⇒ √x = 3 ⇒ x = 3² ⇒ x = 9 b. √x = -10,

no solution as √x is a positive value

c. √x+1=0 ⇒ √x = - 1,

no solution as √x is a positive value

d. √x = 0.1 ⇒  x = 0.1² ⇒ x = 0.01

#1

√x-3=0x-3=0x=3

If square root is over x only x=3²=9

#2

No solutions as -10 is <0

#3

√x+1=0x+1=0x=-1

If root is over x only then no solutions

#4

√x=0.1

x=0.01

at a basketball game a vendor sold a combined total of 116 sodas and hotdogs. The number of hotdogs sold were 36 less than the number of sodas sold find the number of sodas sold and the number of hotdogs sold.

Answers

Answer:  76 Sodas and 40 hot dogs

Step-by-step explanation:

Let S and H represent the numbers of Sodas and Hot dogs.

We are told that:

S + H = 116

We also see that:

H = S - 36

==

Take the second equation's value for H (S - 36) and use it in the first:

S + H = 116

S + (S-36) = 116

2S = 152

S = 76

and therefore H = S - 36, or 40.

76 + 40 = 116  [Checks]

76 Sodas and 40 hot dogs
