Answer:
A=a2=142=196cm²
Answer: 196 cm²
hope this helps :)
Answer:
196cm²
Step-by-step explanation:
All of a square's sides are congruent which means if one side is 14cm then all the other sides have to be 14cm as well.
To find the area you multiply the length and the width (A=l*w)
l=14, w=14
14*14=196cm²
if w=10, x=5, and y=6, what is the surface are of the figure?

In circle K with m/JKL = 30 and JK = 15 units, find the length of arc JL.
Round to the nearest hundredth.
Answer:
7.85
Step-by-step explanation:
Arc Length Formula
[tex]\text{arc length} = 2 \pi r (\frac{\text{angle in degrees}}{360^\circ})[/tex],
where r is radius.
Given information:
m<JKL = 30°
JK = r = 15 units
Substitute in equation and solve.
[tex]\text{arc length} = 2 \pi r (\frac{\text{angle in degrees}}{360^\circ})\\\text{arc length} = 2 \pi (15) (\frac{30^\circ}{360^\circ})\\\text{arc length} = \frac{5}{2} \pi \approx 7.85398\\\text{arc length} = 7.85 \text{ units}[/tex]
5 km= _ m I don't understand
5000
Step-by-step explanation:Measurements can be given in multiple units. Unit conversion is important, especially when dealing with formulas because sometimes only specific units work.
Metric System
In this case, the question is asking about kilometers (km) and meters (m), both of which are in the metric system. Unit conversions are easier in the metric system because it uses prefixes that give you extra information. Each of the prefixes means a different number.
Milli - 1/1000thCenti - 1/100thDeci - 1/10thDeca - 10Kilo - 1000These are not all of the possible prefixes, but they are the most common. This means that a decameter represents 10 meters and 1 millimeter is 1/1000 of a meter.
Conversion
Using the prefixes above, we can tell that 1 kilometer is 1000 meters. So, we can multiply whatever amount of kilometers we have by 1000. This will gives the number of meters.
5 * 1000 = 5000Thus, 5 km = 5000 m.

Answer:
Step-by-step explanation:
The total cost of Tandoori Seasoning is incorrect.
Vijay made an error when multiplying 3.5 ounces by $3.60 .
Cost of both spice blends is actually $23.6.
What is a error?
it is defined as the deviation of an entitiy from its corrected value while calculating.
Now it is given that,
Tandoori Seasoning = 3.5 ounces for $3.60 an ounce
Garam Masala = 4 ounces for $2.75 an ounce
Hence, total cost of Tandoori Seasoning = 3.5*$3.60
⇒ total cost of Tandoori Seasoning = $12.6
and total cost of Garam Masala = 4*$2.75
⇒ total cost of Garam Masala = $11
Therefore, total cost for the spices =cost of Tandoori Seasoning + cost of Garam Masala
⇒ total cost for the spices = $12.6 + $11
⇒ total cost for the spices = $23.6
Hence, we conclude that,
The total cost of Tandoori Seasoning is incorrect.
Vijay made an error when multiplying 3.5 ounces by $3.60 .
Cost of both spice blends is actually $23.6.

The state of Connecticut is approximated by a rectangle 100 mi by 50 mi.
Hartford is approximately at the center of Connecticut. If a meteor hit the
earth within 200 mi of Hartford, find the probability that the meteor landed in
Connecticut.
Answer:
4.0%
Step-by-step explanation:
If we assume that potential impact sites are uniformly distributed over the area, the probability of interest is the ratio of the area of Connecticut to the area of the circle within 200 miles of Hartford.
__
area of circleThe area of a circle with radius 200 miles is ...
A = πr²
A = π(200 mi)² = 40000π mi² ≈ 125,664 mi²
area of CTThe area of a rectangle 100 miles by 50 miles is ...
A = LW
A = (100 mi)(50 mi) = 5000 mi²
probabilityThe probability of interest is the ratio of these areas:
p(impact in CT) = (5000 mi²)/(125664 mi²) ≈ 0.03979
The probability the meteor landed in Connecticut is about 4.0%.

What is the area of the triangle?
Step-by-step explanation:
the area of a triangle is always
baseline × height / 2
where baseline and height are perpendicular (with a 90° angle) to each other.
it does not matter, if the height is inside or outside of the triangle.
so, in our case the area is
4×5/2 = 2×5 = 10 units²
The area of the triangle given in the figure is 10 units².
What is Area?Area of a two dimensional shape is the total region which is bounded by the object's shape.
Given a triangle.
The formula to find the area of the triangle is,
Area = 1/2 × base × height
Base = 4 units
Height = 5 units
Area of the triangle = 1/2 × 4 × 5
= 10 units²
Hence the area of the triangle is 10 units².

A study of the impact of caffeine consumption on reaction time used 24 subjects and divided them into 12 pairs based on the average hours of sleep they got. One randomly assigned member of each pair drank two cups of caffeinated coffee, and the other drank two cups of decaf. Each subject's performance on a standard reaction time test was recorded. The difference for each pair is calculated (caffeinated - decaf). A 95% confidence interval for the mean difference in reaction times is (-1.2, 0.75).
What is a valid conclusion they can make?
a. Because the confidence interval includes more negative numbers than positive, we have convincing evidence that caffeine decreases reaction time.
b. Because the confidence interval includes 0, we don't have convincing evidence that there is a difference in reaction time.
c. Because the center of the interval is -0.225, we have convincing evidence that decreases reaction time.
d. Because the confidence interval includes 0, we have convincing evidence that the true mean difference is 0.
Using the confidence interval, it is found that the correct option regarding the valid conclusion they can make is given by:
b. Because the confidence interval includes 0, we don't have convincing evidence that there is a difference in reaction time.
What are the hypothesis tested?At the null hypothesis, it is tested if there is not a difference in reaction times, that is:
[tex]H_c - H_d = 0[/tex]
At the alternative hypothesis, it is tested if there is a difference, that is:
[tex]H_c - H_d \neq 0[/tex]
The interval contains 0, hence there is not enough evidence to reject the null hypothesis, which means that option B is correct.

Write an equation in slope-intercept form of the line that passes through the point (-6,8) and has a slope of 1/2
Answer:
Step-by-step explanation:
Remark
You can get 1/2 the unknown just by looking at the givens. The slope is just given -- no need to modify it.
The y intercept is a little harder. You need the point for that.
Givens
Slope = 1/2
point = (-6,8)
Formula
y = mx + b
Solution
m = 1/2
y = 1/2x + b To find b,
x = -6y = 88 = 1/2(-6) + b
8 = -3 + b Add 3 to both sides
8 + 3 = b
b = 11
Answer
y = 1/2x + 11
Answer:
y = 1/2x+11
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = 1/2x +b
We can use the point on the line to find b
8 = 1/2(-6) +b
8 = -3+b
Add 3 to each side
8+3 =-3+3 b
11 = b
y = 1/2x+11

a regular number cube is rolled. What is the probability that a 3 will not be rolled?
•1/6
•1/2
•4/5
•5/6
Answer:
5/6
Step-by-step explanation:
Answer:
5/6
Step-by-step explanation:
probability(event) = (number of desired outcomes)/(total number of outcomes)
The total number of outcomes is 6 since there are 6 different sides on the cube.
The number of desired outcomes is 6 minus 1 for rolling a 3, so it is 5.

If RS= 5 , RT = 12 , ST = 7 , and points R, S, and T are collinear, what is the relationship between points R , S , and T ?
The relationship between points R , S , and T is that the sum of the RS and RT will be equal to RT that is RT=RS+ST
What are collinear points?Collinear points are defined as the points which lie on the same line. Here we have three points R, S and T that are collinear.
We have the length equal to:
RS=5, RT=12 ST=7
So we can set the relationship as the sum of the RS and RT will be equal to RT.
So the relation will be given as:-
RT=RS+ST

Answer:
The correct answer is:
P(nuts)=7/9
Step-by-step explanation:
The experimental probability that the next sundae sold will have nuts is
7/9
What is experimental probability?Experimental probability calculates the probability of some event from the results of experiments.
For an event E, we get the experimental probability of that event
[tex]P_e(E) = \dfrac{\text{Number of times E occurred}}{\text{Number of times experiments was done}}[/tex]
where, [tex]P_e(E)[/tex] is denoting the experimental probability of occurrence of E.
We are given that At Frosty Freeze, 14 of the last 18 sundaes sold had nuts.
Therefore,
Probability that the next sundae has nuts is 14/18 = 7/9.
Thus, Probability that the next sundae does not have nuts = 2/9
P(nuts)=7/9

Find a pair of values that make the linear equation y=12x−24 a true statement by filling in the boxes with a valid value of x and y.
Answer:
pair 1: (0, - 24)
pair 2: (1, -12)
Step-by-step explanation:
y = 12x − 24
A pair of values that make the linear equation true:
the easiest value is always 0!!
if x = 0 than plug it in to find y
y = 12(0) − 24 → y = -24
so the pair is (0, - 24)
if x = 1 than plug it in to find y
y = 12(1) − 24 → y = 12 - 24
so the pair is (1, -12)
