Answer:

50

Step-by-step explanation:

Answer: the answer is 50

Step-by-step explanation:

Answer:

The answer is "[tex]y = \frac{1}{4}(x-4)[/tex]".

Step-by-step explanation:

Given:

[tex]Line = y= -4x+3 \\ \\point= (8,1)[/tex]

The formula for the standard Equation of a line:

[tex]\to y= mx +c[/tex]

compare the above line value:

[tex]m= -4\\\\c= 3[/tex]

When a line is perpendicular so, the m value is: [tex]= \frac{1}{4}[/tex]

[tex]\to m_1 \times \m_2 = -1\\\\\to -4 \times m_2= -1\\\\\to m_2 = \frac{-1}{-4}\\\\\to m_2= \frac{1}{4}[/tex]

Line equation when one point and m is given:

[tex]\to (y-y_1) = m (x- x_1)\\\\\to (y-1) = \frac{1}{4}(x- 8)\\\\\to 4y-4 = x- 8\\\\\to 4y = x-8+4\\\\\to 4y = x-4\\\\\to y = \frac{1}{4}(x-4)\\[/tex]

Answer:

7.5m

Step-by-step explanation:

Since we are not asked what to look for we can find the maximum height reached by the ball

The ball reaches its maximum height when dh/dx = 0

dh/dx = -2.4x + 6

0 = -2.4x + 6

2.4x = 6

x = 6/2.4

x = 2.5

Get the max height

Recall:

h =-1.2x^2 + 6x ,

h(2.5) = -1.2(2.5)^2 + 6(2.5)

h(2.5) = -1.2(6.25)+15

h(2.5) = -7.5 + 15

h = 7.5

Hence the maximum height reached by the ball is 7.5m

Answer:

sum of the first 27 terms = -1431

Step-by-step explanation:

[tex] s_{n} = \frac{n}{2} (2a + (n - 1)d)[/tex]

n = 27 terms

first term, a = 25

common difference, d = 19 - 25 = -6

substitute the values into the formula

[tex] s_{27} = \frac{27}{2} (2(25) + (27 - 1)( - 6))[/tex]

[tex] s_{27} = 13.5(50 + 26( - 6))[/tex]

[tex] s_{27} = 13.5(50 - 156)[/tex]

[tex] s_{27} = 13.5( - 106)[/tex]

[tex]s_{27} = - 1431[/tex]

Answer:

250 smaller cuboids

Step-by-step explanation:

Given

Small and Big cuboids

Required

Number of smaller cuboids in the big one

To do this, we calculate the volume of both cuboids.

[tex]Volume = Length * Width * Height[/tex]

For the small cuboid

[tex]V_1 = 10cm * 3cm * 4cm[/tex]

[tex]V_1 = 120cm^3[/tex]

For the big cuboid

[tex]V_2 = 50cm * 30cm * 20cm[/tex]

[tex]V_2 = 30000cm^3[/tex]

The number of small in big is then calculated by diving the volumes

[tex]Number = \frac{V_2}{V_1}[/tex]

[tex]Number = \frac{30000cm^3}{120cm^3}[/tex]

[tex]Number = \frac{30000}{120}[/tex]

[tex]Number = 250[/tex]

Hence, there are 250 small cuboids in the large one

Answer:

Step-by-step explanation:

12 miles is the ride distance

the guy is able to travel at 6 yard per second

Question C asks how many minutes will the trip take

first we have to convert miles to yards....

there are 1760 yards in one mile

12*1760= the total distance to be traveled.. in yards..

21,120 yards

Next we'll figure out the time to travel that distance.. but we're give a rate of travel in seconds...   6  yards every second

so divide the total yards by the seconds.. that are take to travel every second.. in on second he goes 6 yards. so divide the total yards by 6 for each second of travel

21,120 / 6 = 3520 seconds  to go 12 miles  or the 21,120 yards.. it's the same distance in different units

then.. b/c the question is asking for minutes divide the 3,520 seconds by 60.. b/c that's how many seconds are in one minute

3,520 / 60 = 58.6666666666666  minutes  or  58 minutes and 2/3 of one minute.... make sense?

Answer:

It is a triangle

Step-by-step explanation:

This is called Triangle Inequality. We can use its theorem to identify whether these three sides work or not.  The Theorem states, "the sum of the smallest lengths of any two sides must be greater than or equal to the length of the remaining side." If we look at the sides, 11,4,7, we can conclude that these are applicable sides for a triangle because the sum of the two smallest lengths, 4 and 7, are the same value as 11. Therefore, these measurements are a triangle.

Answer:

Third choice, 3/20

Step-by-step explanation:

Add all the numbers on the right side of the chart together:

16 + 12 + 22 + 15 + 26 + 9 = 100

So they're rolled the dice 100 times, and of that, they got a 4 fifteen times. So it's 15/100, simplify that equation and it's 3/20

Simplifying an equation means making an equation have smaller numbers if possible. For this question 15 and 100 can both be divided by 5, it is also the biggest number they can both be divided by, so u divide both by 5 and it's 3 and 20, making it 3/20

Given:

The graph of a function.

To find:

The domain and range of the function.

Solution:

We have, the graph of a function and we need to find the domain and range of the function.

We know that, domain is the set of input values (x-values) and range is the set of output values (y-values).

From the given graph it is clear that function is defined for all values of x except x=0 because as x tends to 0 the function tends to negative or positive infinite. So, domain can be any real number except 0.

[tex]Domain=R-\{0\}[/tex]

[tex]Domain=(-\infty,0)\cup (0,\infty)[/tex]

From the given graph it is clear that the value of function can be any real number except y=0. So, range can be any real number except 0.

[tex]Range=R-\{0\}[/tex]

[tex]Range=(-\infty,0)\cup (0,\infty)[/tex]

Therefore, the correct option is B.

Answer: 2w + 4 = 35

Step-by-step explanation:

Carl's two checked bags and his one backpack together weigh 35kg.

Carl's two checked bags have equal weight so both their weight can be denoted as 2w.

Equation is;

2w + 4 = 35

If you were to solve;

2w + 4 = 35

2w = 35 - 4

w = 31/2

w = 15.5kg

Answer:

5/12

Step-by-step explanation:

The pitch of the roof is 5/12.

Option H is the correct answer.

Pythagorean theorem states that for a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We can apply this theorem only in a right triangle.

Example:

The hypotenuse side of a triangle with the two sides as 4 cm and 3 cm.

Hypotenuse side = √(4² + 3²) = √(16 + 9) = √25 = 5 cm

We have,

We know that the pitch of a roof is defined as the ratio of the vertical rise to the horizontal distance, and is typically expressed as a fraction.

In this case, we are given that the roof is 13 feet long, with 5 feet of vertical rise and x feet of horizontal distance.

Therefore,

The pitch of the roof.

Pitch = vertical rise / horizontal distance

Pitch = 5 / x

We don't know the value of x, but we can use the fact that the roof is 13 feet long to solve it.

Since the horizontal distance and vertical rise form the legs of a right triangle, we can use the Pythagorean theorem to find the value of x.

x² + 5² = 13²

x² + 25 = 169

x² = 144

x = 12

Now,

Pitch = 5 / x

         = 5 / 12

Therefore,

The pitch of the roof is 5/12.

7. The cost of a television with remote control is $649. This amount is $125 more than the cost without remote

control. Find the cost of the television without remote control. Write and equation. Then solve the

equation.

The values from the given situations are required.

The number is 48.

Cost of lawn tractor is $140.

Cost of TV without remote is $387.

Let [tex]x[/tex] be the number

[tex]2(x+(-38))=20\\\Rightarrow x-38=\dfrac{20}{2}\\\Rightarrow x=10+38\\\Rightarrow x=48[/tex]

The number is 48.

[tex]x[/tex] = Cost of lawn tractor

[tex]y[/tex] = Cost of accessories

Cost of lawn tractor is twice of the accessories

[tex]x=2y[/tex]

Total cost of lawn tractor and accessories is $210

[tex]x+y=210\\\Rightarrow 2y+y=210\\\Rightarrow y=\dfrac{210}{3}\\\Rightarrow y=70[/tex]

Cost of lawn tractor is [tex]x=2y=2\times 70=140[/tex]

[tex]x[/tex] = Cost of TV

[tex]y[/tex] = Cost of remote

Cost of TV and remote is $649

Cost is $125 more than the cost without remote control

[tex]x+y=649[/tex]

[tex]x-y=125[/tex]

Adding the equations we get

Answer:

23.84 feet

Step-by-step explanation:

Solving this question above, we using Trigonometric function tangent = Opposite/Adjacent

Opposite side + h = Height of the tree

We are told that:

A student is standing 20 feet away from the base of a tree. He looks to the top of the tree at a 50 degree angle of elevation. His eyes are 5 feet above the ground.

20 feet = Adjacent side = Distance form the tree

tan 50 = (h+5)/20

Cross Multiply

h + 5 = 20 × tan50

h = 20tan50 - 5

h= 18.835071852

h =18.84
