What is the value of x when 5x=6.5?

Answer:

A) [tex]x=42\sin32^\circ[/tex]

Step-by-step explanation:

With respect to our angle, the side opposite to it is [tex]x[/tex], and the hypotenuse is [tex]42[/tex], so the trig ratio we need to use here is sine as [tex]\displaystyle \sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}[/tex]. Hence, if we rearrange the equation so that we solve for the opposite side [tex]x[/tex], then we'll have [tex](\text{hypotenuse})(\sin\theta)=\text{opposite}\rightarrow42\sin32^\circ=x[/tex] as the correct equation.

Answer:

6

Step-by-step explanation:

so if she has $65 and she spent 38.50 you find the difference which is   $26.50 then you divide it by 4 which is 6.62 so yes your right its 6 if you round it

Answer:

6 boxes.

Step-by-step explanation:

65 ≥ 38.50 + 4x    where x is the number of boxes of mints.

65 - 38.50  ≥ 4x

(65-38.40/ 4 ≥ x

x  ≤ 6.625

so the answer is 6 boxes.

This depends on how many blue and red marbles there are in total.

Answer:

D) 2/3

Step-by-step explanation:

If you remove 1 red marble then there is 1 marbles left red.

If you add a blue marble then there is 4 blue marbles.

So it is 4/6 and when you simply it is 2/3.

Answer:

you're screwed

Step-by-step explanation:

don't forget your phone so anyon doesn't ever have to do this

Cindy's house and Jenny's house are 1.33 miles distant from each other.

Speed is defined as the rate at which an object is moving (covering a particular distance). It is a scalar quantity as it defines only the magnitude and not direction.

The SI derived unit for speed is meter per second (m/s).

Given,

Cindy leaves house at 9 am and reaches to jenny house at 10 am

Let the distance between Cindy and Jenny house is x

First, Cindy walks half way to jenny house = x/2

then Cindy take U-turn and walks half way to home = x/4

again Cindy take U-turn and reaches jenny house = 3x/4

Total distance walked by Cindy = x/2 + x/4+ 3x/4

                                                    = x/2 + x

                                                    = 3x/2

Speed of jenny is 2 miles per hour

She walks 3x/2 distance and reaches Jenny house in one hour

⇒ 3x/2 = 2

⇒ 3x = 4

⇒ x = 4/3

⇒ x = 1.33 miles

Hence, distance between Cindy's and jenny's house is 1.33 miles.

The one in the bottom right hand corner.

Step-by-step explanation:

The one in the bottom shows a perfectly symmetric standard curve. In a standard curve, the mean and median and mode are equal.

In a right skewed curve, the median is less than the mean. An example of a right skewed curve is the bottom left hand corner.

In a left skewed curve, the mean is less than the median. An example of a left skewed curve is the top left hand corner.

4 freight cars can be filled by 120 scoops of excavator having a total mass of 156 tons and a volume of 3120 ft³.

In three-dimensional space, volume refers to the entire amount of space occupied by an item. Capacity refers to an object's capacity to contain, absorb, or accept anything (such as a solid material, gas, or liquid).

The amount of matter in a substance or object is measured by its mass.

In the question, we are given that the scoop of an excavator holds 26 ft³of sand.

We are asked if the capacity of a freight car is 39 tons of sand, then how many freight cars can be filled with 120 scoops.

We are also informed that 1 ft³ of sand weighs 0.05 tons.

We first find the mass of sand in one scoop of an excavator.

The volume of sand in one scoop of an excavator = 26 ft³.

Mass of 1 ft³ of sand = 0.05 tons.

∴ Mass of 26 ft³ of sand, that is, the mass of sand in one scoop of an excavator = 26*0.05 tons = 1.3 tons.

∴ Mass of 120 scoops = 120*1.3 tons = 156 tons.

The capacity of one freight car = 39 tons

∴ Number of freight cars in 156 tons = 156/39 = 4.

∴ 4 freight cars can be filled by 120 scoops of excavator having a total mass of 156 tons and a volume of 3120 ft³.

Answer: 65...

Step-by-step explanation: (65 is not on there but..)

35x2= 70 (correct)

5x1= 5 (incorrect)

70-5= 65 (total)

Step-by-step explanation:

we are using the right triangle altitude theorem. it means that in a right-angled triangle the geometric mean of the two segments of the Hypotenuse (the baseline opposite of the 90° angle) equals the altitude.

in other words

h² = p×q

h = height

p, q are the 2 segments of the Hypotenuse.

so, in our case we have

100 = x(x + 21) = x² + 21x

that gives us the following quadratic equation

x² + 21x - 100 = 0

the general solution to a quadratic equating is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = 1

b = 21

c = -100

so,

x = (-21 ± sqrt(21² - 4×1×-100))/(2×1) =

= (-21 ± sqrt(441 + 400))/2 = (-21 ± sqrt(841))/2 =

= (-21 ± 29)/2

x1 = (-21 + 29)/2 = 8/2 = 4

x2 = (-21 - 29)/2 = -50/2 = -25

x2 would give us negative lengths for the triangle, which does not make sense.

so, x = 4 is our solution.

that makes the segments of the Hypotenuse 4 and (4+21) = 25 units long (the whole baseline is then 4+25 = 29).

Answer:

12.5 unit square

Step-by-step explanation:

The area of a trapezoid is calculated with the following formula:
