Find the value of x of the given right triangle.
Answers
Answer:
In the right triangle, the side a=[tex]4[/tex] and the hypotenuse c=[tex]7[/tex].
To find: the value of x
We have,
[tex]a=6[/tex] and [tex]c=7[/tex]
Now,by the pythagorean theorem,
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
Substitute the values,
[tex] {6}^{2} + {x}^{2} = {7}^{2} [/tex]
[tex]36 + {x}^{2} = 49[/tex]
Subtract 36 from each sides,
[tex] {x}^{2} = 13[/tex]
Take square root from each sides,
[tex]x = \sqrt{13} [/tex]
Hence, the value of x is [tex]\sqrt{13}[/tex].

Orange traffic cones comes in a variety of sizes. Approximate the volume, in cubic inches, of a traffic cone
that has a height of 2 feet and a diameter of 16 inches. Round your answer to the nearest tenth. Use 3.14
for a.
Answers
Answer:
V = 1607.7 in^3
V = 0.94 ft^3
Step-by-step explanation:
To find the volume of a traffic cone, use the formula for the volume of a cone: (1/3)*π*h*r^2
h = height
r = radius of cone
Step 1: determine variables and units
2 feet = 24 inches
diameter = 2 * radius
radius = (1/2) * diameter = (1/2)*16 in = 8 inches
Step 2: determine volume
V = (1/3)*π*h*r^2
V = (1/3)*3.14*24*(8)^2
V = 1607.7 in^3
Optional step 3: determine volume in ft^3
h = 2 ft
r = 0.67 ft
V = (1/3)*π*h*r^2 = (1/3)*3.14*2*(0.67)^2
V = 0.94 ft^3
A candle on Pauline’s dresser is 4 inches tall and burns at a rate of 0.6 inches per hour. How many hours will it take for the candle to burn down to a height of 1.3 inches?
Answers
The time taken for the candle to burn down to a height of 1.3 inches is 4.5 hours
What is a Linear Function ?A linear function is what can be written in the form of
y =mx+c
The rate at which the candle is burning is 0.6 inches/ hour
The initial height is 4 inches at t=0
The straight line equation can be written for this as
y =mx +c
as m = -0.6
at x = 0 , y = 4 therefore c =4
y = -0.6x +4
The time at which y = 1.3 inches is
1.3 = -0.6x +4
-2.7 = -0.6 x
x =4.5
4.5 hours is the time taken for the candle to burn down to a height of 1.3 inches.

Answer: 6 [tex]\frac{3}{4}[/tex] cups of water

First, we will turn 12 ounces into units of cups.
12 / 8 = 1.5 cups
Now, we will subtract the start of the month from the end of the month.
8.25 cups - 1.5 cups = 6.75 cups
Lastly, we will turn it into a mixed number.

Answer:
a = 63
b = 117
c = 63
Step-by-step explanation:
The sum of interior angles in a triangle is = 180
so the measure of a:
85 + 32 + a = 180 add like terms
117 + a = 180 subtract 117 from both sides
a = 63
a and be are supplementary angles so their sum is equal to 180
180 - 63 = 117 is the b's value
since a and c are on a pair of parallel lines, their value must be equal therefore the value of c is also 63

The value of x is 7 and the measure of ∠1 is 99
How to solve for x?The given parameters are:
∠NMQ = 5x + 19∠MQN = 8x - 11∠QNM = 11x + 4The sum of angles in a triangle is 180.
So, we have:
5x + 19 + 8x - 11 + 11x + 4 = 180
Evaluate the like terms
24x = 168
Divide both sides by 24
x = 7
Hence, the value of x is 7
How to determine the measure of ∠1?The angles on a straight line add up to 180.
This means that:
∠1 + ∠QNM = 180
Subtract ∠QNM from both sides
∠1 = 180 - ∠QNM
Substitute ∠QNM = 11x + 4
∠1 = 180 - 11x - 4
Substitute x = 7
∠1 = 180 - 11 * 7- 4

∠1 = 99

By assuming that the motion of the plastic disc thrown by Mary is a projectile motion, the missing values are 4 and 3 respectively.
How to determine the missing height?Since we're assuming that the motion of the plastic disc thrown by Mary is a projectile motion, it simply means that the motion can be represented by a quadratic function (parabolic).
For a projectile motion, the height of the disc at the time when it's at the top would be the same (equal). Thus, we can logically deduce that:
Height at time (t = 1 seconds) = Height at time (t = 5 seconds)
4 = A.
Similarly, Height at time (t = 0 seconds) = Height at time (t = 6 seconds)
3 = B.

the spec sheet for the actual 1968 corvette shows the front frame dimension to be 32.875 inches. what would this measurement be, in both fractional and decimal form, on the hot wheels 1:64 model? which form of the measurement would be easier to work with?
Answers
Answer:
0.513671875 = 263/512 inches
easier to use: depends on the measurement tool
Step-by-step explanation:
The model dimension is found by multiplying the actual dimension by the scale factor.
__
model dimensionmodel frame dimension = actual frame dimension × 1/64
= (32.875 inches)/64 = 0.513671875 inches
In fractional form, this is ...
(32 7/8) / 64 = (263/8) / 64 = 263/512 . . . inches
__
ease of useIt is unlikely that a casual hobbyist will have access to tools that measure with a resolution finer than 0.0001 inches. More common would be a measurement resolution of 0.001 inches. Using such tools, the rounded decimal value 0.5137 or 0.514 inches would be more useful than the fractional measurement.
It is possible that an optical measuring device could be available that would present its result as a fraction of an inch. If such a tool were used, the fractional measurement value would provide an appropriate point of comparison.
In short, the measurement easiest to work with depends on the tool being used to make the measurement.

What is compound interest?Interest on interest, or compound interest, is the adding of interest to the principal sum of a loan or deposit. It's the outcome of reinvesting interest rather than paying it out so that interest is received on the principal plus previously collected interest in the next quarter.,
[tex]A = P(1+ \dfrac{r}{n})^{nt}[/tex]
where A is the final amount
P is the principal amount
r is the rate of interest
n is the number of times interest is charged in a year
t is the number of years
The principal amount is 1000 dollars, while the rate of interest is 6.75% which is compounded monthly. Therefore, the time it will need for the account to reach $2500 is,
2500 = 1000[1+(0.0675/12)¹²ˣⁿ
