Answer:

4.22in

Step-by-step explanation:

Given data

Volume= 601in^3

Height= 10.7in

Radius= ??

The expression for the volume of a cylindrical bucket is

V=πr^2h

substitute

601= 3.14*r^2*10.7

601= 33.598r^2

601/33.598= r^2

17.88=r^2

square both sides

r= √17.88

r= 4.22 in

Hence the radius of the bucket is 4.22in

Given:

A train travels 288 km at a uniform speed.

If the speed has been 4 km per hour more it would have taken one hour less for the same journey.

To find:

The initial speed of the train.

Solution:

Let x km/h be the initial speed on the train.

New speed of train = (x+4) km/h

We know that,

[tex]Time=\dfrac{Distance}{Speed}[/tex]

Time taken by the train initially to cover 288 km is [tex]\dfrac{288}{x}[/tex] hours.

New time taken by the train to cover 288 km is [tex]\dfrac{288}{x+4}[/tex] hours.

It is given that If the speed has been 4 km per hour more it would have taken one hour less for the same journey.

[tex]\dfrac{288}{x}-\dfrac{288}{x+4}=1[/tex]

[tex]\dfrac{288(x+4)-288x}{x(x+4)}=1[/tex]

[tex]288x+1152-288x=x^2+4x[/tex]

[tex]1152=x^2+4x[/tex]

[tex]0=x^2+4x-1152[/tex]

Splitting the middle term, we get

[tex]x^2+36x-32x-1152=0[/tex]

[tex]x(x+36)-32(x+36)=0[/tex]

[tex](x+36)(x-32)=0[/tex]

[tex]x=-36,32[/tex]

We know that the speed cannot be negative. So, the only possible value of x is 32.

Therefore, the speed of the train is 32 km/h.

Answer:

∠ R = 30°

Step-by-step explanation:

The secant- secant angle R is half the difference of its intercepted arcs, so

∠ R = [tex]\frac{1}{2}[/tex] (103 - 43)° = [tex]\frac{1}{2}[/tex] × 60° = 30°

Answer:

A) 48° + 75°

Step-by-step explanation:

All triangles contain 180°

180° - 57° = 123°

A) 48° + 75° = 123°

B) 57° + 57° = 114°

D) 63° + 70° = 133°

A) 70° + 83° = 153°

[tex]\huge{\textbf{\textsf{{\color{pink}{An}}{\red{sw}}{\orange{er}} {\color{yellow}{:}}}}}[/tex]

The answer is A. 48⁰ and 75⁰

Thr sum of all triangles is 180⁰

so, 180⁰ – 57⁰ = 123⁰

The sum of other two angles should be 123⁰,

so,...

48⁰ + 75⁰ = 123⁰

Step-by-step explanation:

Given

In a circle

Radius (r) = 3 / 4 inches

Diameter (d)

= 2 * r

= 2 * 3 /4

= 3 /2 inches

Hope it will help :)❤

The diameter of a circle with a radius of 3/4 inches is 6/4 inches.

We are given that;

The radius of a circle = 3/4 inches

Now,

The diameter of a circle is twice the radius of the circle. Therefore, to find the diameter of a circle with a radius of 3/4 inches, we need to multiply 3/4 by 2. We can do this by multiplying the numerators and the denominators:

(3/4) x 2 = (3 x 2)/(4 x 2) = 6/8

We can simplify this fraction by dividing both the numerator and the denominator by their greatest common factor, which is 2:

6/8 = (6/2)/(8/2) = 6/4

Therefore, by the circle the answer will be 6/4.

We have:

ab = bc (hypothetical)

so the triangle ABC is isosceles at B

we have: bd is the height of the triangle ABC, so BD is perpendicular to AB

Consider the triangle ABD and the right triangle ACD have:

AB = BC (hypothesis)

BD is the common edge

So the triangle ABD = triangle ACD (hypotenuse - acute angle)

hence the angle ABD = angle ACD

Answer:

84

Step-by-step explanation:

(The sum of 82, 74, and 96 would be 252. And the count of numbers included in the question would be 3, and so you would divide the count from the sum as shown like Sum/Count. In this case it'd be 252/3, and that would equal 84.)

Average =  Sum/Count  

=   252/3  

=  84

Answer:

Solution = Infinitely many

Step-by-step explanation:

y = -x + 1

y - 1 = -x

y = -x + 1

y = -x + 1 (Multiply by -1)

y = -x + 1

-y = x - 1

0 = 0

Since 0 = 0 is true, this is an identity solution that has an infinite set of solutions
