Answer:
Length = 16 inches and width = 12inches
Step-by-step explanation:
A = 192 in² . The width is 4 + 1/2x. therefore let x = length
Area = LW
192 = x(4 + 1/2 x)
192 = 4x + 1/2x²
384 = 8x + x² Multiply each term by 2 to make a
384 + 16 = x² + 8x + 16 Complete the square
400 = (x + 4)²
[tex]\sqrt{400} = \sqrt{(x + 4)^2}[/tex]
± 20 = x + 4
20 = x + 4 or -20 = x + 4
20 - 4 = x or -20 - 4 = x
16 = x or -24 = x reject the negative amount
Length = 16
width = 4 + 1/2(16); 4 + 8 = 12
find possible lenth and breadth of the rectangle whose area is given by the expression x power 2 +6x +8
[tex]x^2 +6x +8\\\\=x^2 + 4x +2x +8\\\\=x(x+4) +2(x+4)\\\\=(x+2)(x+4)\\\\\text{Possible length and breadth of the rectangle are (x+4) and (x+2) respectively.}[/tex]

Answer:
88 degrees, 44 degrees
Step-by-step explanation:
The total of angles in a triangle is 180 degrees
so, 48+x+x-44=180
48-44+x+x=180
4+2x=180
-4 on both sides
2x=176
x=88

Why 10 is down how we get it?
triangle: 3x-1,4x+1,3x
perimeter:70cm
area:A2
find A
Answer:
A = 210 cm²
Step-by-step explanation:
Perimeter of the triangle = the sum of the sides of the triangle.
70 = (3x - 1) + (4x + 1) + (3x)
70 = 10x
7 = x The length of the sides of the triangle are 3x - 1 = 20; 4x + 1 = 29 and
3x = 21.
Looking at the given information, this triangle is a special type of triangle because the area of a triangle is Area = 1/2 bh and you do not know which side is the base and height of the triangle.
Trying a² + b² = c² to see if it is a right triangle. 20² + 21² = 29 ² ; yes it is a right triangle and now we know that the base and height is 20 and 21. The longest side is the hypotenuse in a right triangle
A = 1/2bh
A = 1/2 (20)(21)
A = 10 · 21
A = 210 cm²

What is the y-intercept of y = 4x? Choose 1 answer:
Answer:
B (0,0)
Step-by-step explanation:
The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept y=mx+b. Using the slope-intercept form, the y-intercept is 0. b=0
The y-intercept of y=4x is (0, 0)
Option B is correct
Y-intercept of a linear equationThe slope-intercept of a line is given as:
y = mx + c
where m represents the slope
c represents the y-intercept
The given equation is y = 4x
To find the y-intercept, substitute x = 0 into the equation and solve for y
y = 4(0)
y = 0
Therefore the y-intercept of y=4x is (0, 0)

Answer:
w = 38% or 37%
w = 37.7162629758% exact
Step-by-step explanation:
Lets say c = 100
If k = 15, 100 is decreases by 15% 2 times.
15% of 100 = 15
100 - 15 = 85
d = 85
Now lets find a
85 times .85 = 72.25
Now find what percent of 72.25 you have to add to itself to get 100
100 - 72.25 = 27.75
27.75 divided by 72.25
37% rounded
37.7162629758% exact

Mr. Jackson likes to play a game in which rolling a 4 on a number cube doubles your score. He wants to know the probability that he will roll a 4 exactly 3 times out of 10 rolls. Define the variables for describing a binomial probability, and identify their values in this experiment.
Answer:
Step-by-step explanation:
Binomial Probability
P(x) = n!/(n-x)!x! * p^x q^(n-x)
P(x) = probability there will be x required outcomes (here x is 3)
n = number of trials (here it is 10)
p = probability of 1 required outcome (getting a 4) on a single roll ( = 1/6).
q = probability of required outcome not occurring on a single roll.
p = 1/6
q = 1 -1/6 = 5/6
n = 10
x = 3
So the required probability
= 10!/ 7!3! (1/6)^3 (5/6)^7
= 0.155.

Answer:
V = 113.1
Step-by-step explanation:
V= 4/3 π r^3
V= 4/3 x 3.14 x 3^3
V= 4.19 x 27
V= 113.13
rounded to 113.1
In this question all the required information is given so we'll simply have to solve.
[tex]\large\boxed{\bold{V= \ \frac{4}{3}\pi{r}^{3}}}[/tex]
Let's substitute the values according to the formula.
[tex]\bold{ V= \frac{4}{3}×\pi×{3}^{3}}[/tex]
[tex]\bold{=113.0973355 \ {m}^{3}}[/tex]
Now, we can round off to the nearest tenth.
If the value in hundredths place is greater than 5 you'll have to round up. If not you'll have to keep it as it is.
In this, the value in hundredths place is greater than 5 so we'll have to round up by adding 1 to the tenths place.
[tex]\large\boxed{\bold{V= 113.1 \ {m}^{3}}}[/tex]
Therefore, the volume of the given sphere is 113.1 cubic meters.

Mr. and Mrs. Ozawa are driving their family to a vacation spot 496 miles away. They want to get there in 8 hours. What is the average speed they need to drive?
The average speed Mr and Mrs Ozawa should drive is 62 miles per hour.
What is the difference between average and instantaneous speed?The average speed is calculated for a period of time while instantaneous speed is calculated at certain instant of time.
For instantaneous speed and average speed are equal for an object moving with constant speed.
The total distance travelled is given as 496 miles.
And, the total time taken is 8 hours.
Average speed can be calculated by taking the ratio of total distance and time as follows,
Total distance ÷ Total time
⇒ 496 ÷ 8
⇒ 62
Hence, the average speed is given as 496 miles per hour.
