If you are traveling 543 miles and you know that your car gets 18 miles per gallon of gasoline, approximately how many gallons o

Inga [223]

we know that

the car gets 18 miles per -----------> 1 gallon of gasoline

so

for 543 miles ---------------------> x gallons of gasoline

by proportion

543/18=x/1---------->x=543/18------->x=30.17 gallons

therefore

the answer is

30.17 gallons

T=√k(k-b)(k-m).... make b the subject of the formula

Liono4ka [1.6K]

Answer:

b = -T²/k(k-m) + k

Step-by-step explanation:

Given the equation T =√k(k-b)(k-m), we are to make b the subject of the formula

Square both sides

T² = (√k(k-b)(k-m))²

T² = k(k-b)(k-m)

T²/k(k-m) = k-b

Rearrange

k - b = T²/k(k-m)

b - k = - T²/k(k-m)

Add j=k to both sides

b - k + k = - T²/k(k-m) + k

b = -T²/k(k-m) + k

This gives the required expression

The length of the hypotenuse of the right triangle is 25 cm, the length of one of the legs is 10 cm. What is the length of the s

Anna007 [38]

Answer:

21 cm

Step-by-step explanation:

Call the triangle ABC, with the right angle at B, the hypotenuse AC=25, and the given leg AB=10. The altitude to the hypotenuse can be BD. Since the "other leg" is BC, we believe the question is asking for the length of DC.

The right triangles formed by the altitude are all similar to the original. That means ...

AD/AB = AB/AC . . . . . . ratio of short side to hypotenuse is a constant

Multiplying by AB and substituting the given numbers, we get ...

AD = AB²/AC = 10²/25

AD = 4

Then the segment DC is ...

DC = AC -AD = 25 -4

DC = 21 . . . . . centimeters

Given: CP is perpendicular to AB, CP bisects AB, Prove: CA=CB

expeople1 [14]

Answer:

Proved CA=CB

Step-by-step explanation:

Given,

In ΔABC, CP is perpendicular to AB.

And CP bisects AB.

So, AP=PB and ∠CPA=∠CPB=90°

The figure of the triangle is in the attachment.

Now, In ΔACP and ΔBCP.

AP = PB(given)

∠CPA = ∠CPB = 90°(perpendicular)

CP = CP(common)

So, By Side-Angle-Side congruence property;

ΔACP ≅ ΔBCP

According to the property of congruence;

"If two triangles are congruent to each other then their corresponding sides are also equal."

Therefore, CA = CB (corresponding side of congruent triangle)

CA = CB Hence Proved
