Answer:

- 27/64

Step-by-step explanation:

Third power = cubed = multiplying by itself three times

(-3/4)^3 = (-3/4) * (-3/4) * (-3/4) = 9/16 * (-3/4) = - 27/64

Answer:

2 ft/min

Step-by-step explanation:

Given that :

Kim was waling down a path for 4 minutes the elavation changed at the same rate altogether it dropped 8 feet what was the change in elavation each minute?

Time taken it wall down the path = 4 minutes

Rate of change of elevation is the same

Distance = 8 Feets

Therefore, change in elevation per minute :

Distance dropped / time taken to drop that distance

8 Feets / 4 minutes

2 Feets / minute

Change in elevation = 2 Feets per minute

Answer:

x=0.1

Step-by-step explanation:

-3.7-9.7x=7x-5.2

x=0.08982

x=0.1

Answer:

(4, -9)

Step-by-step explanation:

Find the distances between the x and y coordinates of point T and the midpoint:

2 - 0 = 2 (distance of x values)

-2 - 5 = -7 (distance of y values)

Add these two values to the coordinates of the midpoint:

2 + 2 = 4 (x value of point S)

-2 - 7 = -9 (y value of point S)

So, point S is at (4, -9)

Answer:

It started on the 55th floor.

Step-by-step explanation:

We can work backwards from the 54th floor. Since we are working backwards, if the elevator goes up, we will subtract and if it goes down, we will add. Starting with 54, we get 54 + 5 = 59, then 59 - 9 = 50, then 50 + 2 = 52, then 52 - 6 = 48, then 48 + 14 = 62, then 62 - 7 = 55.

Answer:

Graph A

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Since we are dealing with a slope of zero, we replace m with 0:

y = 0x + b

y = b

Here, we see that we would have a horizontal line. Therefore, graph A would be our answer.

Answer:

A

Step-by-step explanation:

A slope of zero is a horizontal line, because it does not change vertically

A would be the graph of a line with a slope of zero

Answer:

[tex]\Huge \boxed{\mathrm{B. \ 6}}[/tex]

Step-by-step explanation:

We can apply the Intersecting Secant-Tangent Theorem.

TV is the secant.

VW is the tangent.

VW² = VT × VU

(x+6)² = (5+x+4) × (x+4)

Combine the terms in bracket.

(x+6)² = (x+9)(x+4)

Expand brackets on both sides of the equation.

x²+12x+36=x²+13x+36

Subtract x² from both sides.

12x+36=13x+36

Subtract 12x from both sides.

36=x+36

Subtract 36 from both sides.

0=x

WV = x+6

x=0

WV = 0+6 = 6

The measure of the tangent WV is 6.

Answer:

D. 63°

Step-by-step explanation:

a = 27°

b = 180° - (a + 27°)

b = 180° - (27° + 27°)

b = 180° - 54°

b = 126°

By inscribed angle theorem:

c = 1/2 b = 1/2 * 126°

c = 63°

The measure of angles a, b, and c in the given figure are 27°, 126°, and 63°, respectively.

An isosceles triangle is one with two equal-length sides. It is sometimes stated as having exactly two equal-length sides, and sometimes as having at least two equal-length sides, with the latter form containing the equilateral triangle as a particular case.

In the triangle ORQ, the two sides of the triangle OR and OQ are the radius of the triangle, therefore, the length of the two sides will be.

Since the two sides of the triangle are equal, therefore, the triangle will be an isosceles triangle, with the angle opposite to the same length measuring the same. Therefore,

∠OQR = ∠ORQ

a = 27°

Now, in a triangle, the sum of the measure of all the angles is equal to 180°. Therefore, we can write,

∠OQR + ∠ORQ + ∠QOR = 180°

a + 27° + b = 180°

27° + 27° + b = 180°

b = 180° - 27° - 27°

b = 126°

Further, In a circle, the measure of the angle formed by the chord in the centre of the circle is twice the measure of the angle formed by the same chord on any point in the circle. Therefore,

∠QOR = 2∠QPR

b = 2 × ∠QPR

126° = 2 × ∠QPR

∠QPR = 126° / 2

∠QPR = 63°

Hence, the measure of angles a, b, and c in the triangle are 27°, 126°, and 63°, respectively.

Answer:

speed of Jim's train = 35 mi/h

speed of Sarah's train = 35 +20 mi/h = 55 mi/hour

Step-by-step explanation:

Let the speed of Jim's train be x mi/h

Given, Sarah and Jim leave a train station at the same time traveling 20mi/h faster that Jim’s train.

speed of Sarah's train = x + 20 mi/h

we know distance = speed * time

time = 3 hours

distance traveled by Sarah's train = 3*(x+20) = 3x+60 miles

distance traveled by Jim's train = 3*x =  3x miles

It is not given that if trains are moving in same or opposite direction.

__________________________________

if they are travelling in same direction

Then, then distance between them = total distance traveled by

faster train -  total distance traveled by

slower train = 3x +60 -3x = 60 miles

which is wrong as the two trains are 270 miles apart

hence, they are travelling in opposite direction

In this case

distance between them = total distance traveled by

faster train +  total distance traveled by

slower train = 3x +60 + 3x = 6x + 60 miles

given that the trains are 270 miles apart

6x + 60 miles = 270 miles

6x = 270 - 60 = 210

x = 210/6 = 35

Thus, speed of Jim's train = 35 mi/h

speed of Sarah's train = 35 +20 mi/h = 55 mi/hour

Answer:

6:4:3.....................

The ratio between A, B, and C is 6:4:3.

To determine the ratio between A, B, and C based on the given information, we can set up the following equations:

2% of A = 3% of B

4% of C = 3% of B

Let's solve for the variables and find the ratio:

First equation: 2% of A = 3% of B

0.02A = 0.03B

A/B = 0.03/0.02

A/B = 1.5

Second equation: 4% of C = 3% of B

0.04C = 0.03B

C/B = 0.03/0.04

C/B = 0.75

Now, let's express the ratio A:B:C based on the ratios we found:

A:B = 1.5:1

B:C = 1:0.75

To obtain a common ratio, we can multiply both ratios by 4:

A:B = 6:4

B:C = 4:3

Combining these ratios, we have:

A:B:C = 6:4:3

Therefore, the ratio between A, B, and C is 6:4:3.

first step to balance the equation is :

multiply AL by 2 to match the amount of aluminum on the other side

but then you have to deal with the amount of O from both sides, we need to find the least common multiple between 2 and 3 which is 6

the best thing to balance the equation is to multiply O2 by 3 and O3 by2, then deal with the amount of AL which is 4 on the other side. last step is to multiply AL by 4 to balance the equation.

Answer:

The second object (4000 grams) had more kinetic energy

Step-by-step explanation:

Use the equation KE = 0.5mv², where m is the mass and v is the velocity.

Find the kinetic energy of the first object:

KE = 0.5(2000)(2 m/s)²

KE = 4000 J

Find the kinetic energy of the second object:

KE = 0.5(4000)(3 m/s)²

KE = 18000 J

So, the second object (4000 grams) had more kinetic energy.

The second object of mass 4000 grams will have more kinetic energy than the first mass.

The energy that an object has as a result of motion is known as kinetic energy. It is described as the effort required to move a mass-determined body from rest to the indicated velocity.

Use the equation KE = 0.5mv², where m is the mass and v is the velocity.

The kinetic energy of the first object:

KE = 0.5(2000)(2 m/s)²

KE = 4000 J

The kinetic energy of the second object:

KE = 0.5(4000)(3 m/s)²

KE = 18000 J

Therefore, the second object (4000 grams) had more kinetic energy.

Answer:

Total money with them = Rs. 150

Step-by-step explanation:

Let money with gopal be x

let money with laxmi be y

Given

Gopal gives Rs 10 from his money to Laxmi her money becomes double thanthat of the remaining money of Gopal

Money left with gopal after giving Rs 10 = x-10

money with Laxmi after getting rs 10 = y+10

according to given condition

money with laxmi = 2*money left with Gopal

y+10 = 2(x-10)

___________________________________________________

Laxmi gives Rs 10 to Gopal his moneyis still Rs 10 less than the remaining money of Laxmi.

Money left with Laxmi after giving Rs 10 = y-10

money with Gopal after getting rs 10 = x+10

according to given condition

money with laxmi -10 =money  with Gopal

y-10-10 =x+10

y-20 = x+10

=> y = x+10+20

y = x+30

substituting y = x+30 in    y+10 = 2(x-10)

x+30 +10 = 2(x-10)

x+40 = 2x-20

=>40+20 = 2x-x

=> x = 60

y = x+30 = 60+30 = 90
