Answer:

c.  21, 85

Step-by-step explanation:

Define the variables:

Let the two numbers be x and y, where x > y.

Given information:

Create two equations from the given information and defined variables:

[tex]\begin{cases}x = 4y + 1\\x + y = 106\end{cases}[/tex]

Substitute Equation 1 into Equation 2 and solve for y:

[tex]\implies (4y+1)+y=106[/tex]

[tex]\implies 4y+1+y=106[/tex]

[tex]\implies 5y+1=106[/tex]

[tex]\implies 5y+1-1=106-1[/tex]

[tex]\implies 5y=105[/tex]

[tex]\implies \dfrac{5y}{5}=\dfrac{105}{5}[/tex]

[tex]\implies y=21[/tex]

Substitute the found value of y into the second equation and solve for x:

[tex]\implies x+21=106[/tex]

[tex]\implies x+21-21=106-21[/tex]

[tex]\implies x=85[/tex]

Therefore, the two numbers are 21 and 85.

Step-by-step explanation:

The length of AB is 4.47 units, the length of CD is 2.83 units and the length of EF is 5 units.

We are given different right angled triangles.

We need to find AB, CD and EF

We will do this by using the Pythagoras theorem.

Pythagoras theorem states that:

Hypotenuse² = Base² + Perpendicular²

For AB,

Hypotenuse = AB

Base = 2 units

Perpendicular = 4 units

So, we get that:

AB² = 2² + 4²

AB² = 4 + 16

AB² = 20

AB = √ 20

AB = 2√5 units

AB = 4.47 units.

For CD:

Hypotenuse = CD

Base = 2 units

Perpendicular = 2 units

So, we get that:

CD² = 2² + 2²

CD² = 4 + 4

CD² = 8

CD = √ 8

CD = 2√2

CD = 2.83 units

For EF:

Hypotenuse = EF

Base = 4 units

Perpendicular = 3 units

So, we get that:

EF² = 4² + 3²

EF² = 16 + 9

EF² = 25

EF = 5 units.

Therefore, we get that, the length of AB is 4.47 units, the length of CD is 2.83 units and the length of EF is 5 units.

Answer:

$2,750 = $200x + $750

10 cars to meet the goal

Step-by-step explanation:

We will pull details we need to solve out of the question:

     If her goal is to make 2,750 dollars, the money earned must equal at least $2,750.

     If she's already made $750, then we can subtract that from what is needed left to make (or add it to what needs to be made).

     Finally, she makes $200 per car. Let x equal the number of cars she sells.

Next, we will write an equation:

     $2,750 = $200x + $750

Lastly, we will solve this equation.

     $2,750 = $200x + $750

     $2,000 = $200x

     10 = x

           She needs to sell 10 cars to meet her goal.

Step-by-step explanation if c is for 6 its 1 p

Answer:

C/6

Step-by-step explanation:

you have c pieces to share with 6 friends.

Using the mass ratio, the spacecraft's velocity was determined to be 7.7025 km/s.

Here, c = 2.7 km/s, t = 30s, R = 20

On substituting the values of 'R', 't', 'v', we get:

v = -0.0098 ( 30) + 2.7 ( ln (20))

=> v = - 0.294 + 2.7 (2.995)

=> v = 7.7025 km/s

A spaceship is a machine or vehicle built to travel through space. Spacecraft are a form of artificial satellite used for a wide range of tasks, such as communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and cargo and person transfer.

Following are the main distinctions between spaceships and rockets: The spacecraft is launched into space by rockets, which then crash to Earth. Rockets are never manned, whereas spacecraft can be either manned or unmanned. Additionally, spacecraft cannot match the power of rockets.

Using proportions, it is found that the garage is 14 millimeters wide in the drawing.

What is a proportion?

A proportion is an equation that sets two ratios at the same value. For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls)

The rule of three is:

7 millimeters - 4 meters

x millimeters - 8 meters

Applying cross multiplication

The value of the greatest of the three is -16

Let the smallest of the integers be x - 2

So, the other integers are x - 1 and x

The sum of the integers is given as

Sum = -51

So, we have the following equation

x - 2 + x - 1 + x = -51

Evaluate the like terms in the above equation

So, we have the following equation

3x = -48

Divide both sides of the equation by 3

So, we have the following equation

x = -16

The measure of the z value from the given figure is 6 2/3.

We need to find the unknown value for the given figure.

In trigonometry, there are six trigonometric ratios, namely, sine, cosine, tangent, secant, cosecant, and cotangent. These ratios are written as sin, cos, tan, sec, cosec(or csc), and cot in short. Trigonometric ratios can be used to determine the ratios of any two sides out of a total of three sides of a right-angled triangle in terms of the respective angles.

Using trigonometric ratios we can find the z value.

From the given figure, tan θ = 4/6 ----(I) and also tan θ = z/10 ----(II)

Now, equation (I) = (II)

⇒ 4/6 = z/10

⇒ 4 × 10 = z × 6

⇒ 6z = 40

⇒ z = 40/6

⇒ z = 20/3

⇒ z = 6 2/3

Therefore, the measure of the z value from the given figure is 6 2/3.

Answer: You can use Math apps to help you easily

Step-by-step explanation:

It takes 60 minutes (1 hour) for the Blue Line train and the Yellow Line train to be at the station at the same time, using their running time LCM.

The time that it will take the Blue Line train and the Yellow Line train to meet again at the station is determined using the Least Common Multiple or Factor.

The LCM is the smallest positive integer that is evenly divisible by both numbers, 10 and 12.

For instance, the LCM of 10 and 12 include 60 and 120 with 60 as the least.

The time the Blue Line runs is every 10 minutes.

The time the Yellow Line runs is every 12 minutes.

The LCM of 10 and 12 is 60 because 10 and 12 can divide 60 without a remainder.

Thus, it will take 60 minutes for the two trains to meet again at the station.

Step-by-step explanation:

N=1/4, D=2/3

whole pizza=1

r=remainder pizza

1 - 1/4 - 2/3 =r

(1 - 1/4 - 2/3 =r)*12 ==> multiply by 12 to get rid of denominators

12 - 12/4 - 12*2/3=12r

12-3-24/3=12r

9-8=12r

12r=1

r=1/12 of a pizza left

Answer:

1/12

Step-by-step explanation:

the common number of 3 and 4 is 12. You multiply 1/4 by three and you get 3/12, and you multiply 2/3 by 4 and you get 8/12. You add 8 and 3 and you get 11, that's the number that indicates the part of the eaten pizza. 12-11=1. 1/12 left from the pizza.

The formula for calculation of circumference of the circle = d π or 2πr where d is diameter of circle and r is the radius of circle

As given in the question the circumference of the circle whose diameter is 2 cm is 6.28cm and we come to know that value of π used here is 3.14 and not 22/7

So, the circumference of the circle whose diameter is 1cm = d π

              = 1 π

            = 1 3.14

                                                                                          = 3.14 cm

Vertical Angle Theorem: two angles that are formed by two intersecting lines and are opposite each other are equal

The value of x is 23 because Angle FGI and Angle HGC are vertically opposite angles, the answer is 23.

It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.

It is given that:

The triangle and two parallel lines are shown in the picture.

As we know, from the definition of the vertically opposite angle, two lines intersect each other at the intersecting point.

Angle FGI = Angle HGC = 14 degrees

4x = 78 + Angle HGC

4x = 78 + 14

4x = 92

x = 92/4

x = 23

Thus, the value of x is 23 because Angle FGI and Angle HGC are vertically opposite angles, the answer is 23.
