Answer:
-7
Step-by-step explanation:
Basically it's just 6°C - 13°C = -7°C
Hope this helps.
Based on the original temperature and the amount it changed by, the new temperature is -7 °C.
The original temperature was 6 °C and this decreased by 13 °C.
The new temperature can be found by:
= Starting temperature - Temperature change
Solving would give:
= 6 - 13
= -7 °C.
In conclusion, the new temperature is -7 °C.

The length of the one of the legs of a right triangle is 8m and the hypotenuse is 12m
Answer:
other leg = 8.944271910
Step-by-step explanation:
If you are trying to figure out the other leg you have to use pythagorean therom:
c^2 - a^2 = b^2
(12)^2 - (8)^2 = b^2
144 - 64 =b^2
80 = b^2
√80 = b
8.944271910 = b
Detergent A contains 48 fluid ounces and cleans 16 loads of dishes. Detergent B contains 76 fluid ounces and cleans 38 loads of dishes. Which comparison of the detergents is accurate?
Detergent A uses exactly 1 fluid ounce per load more than detergent B.
Detergent A uses exactly 1 fluid ounce per load less than detergent B.
Detergent A uses less than 1 fluid ounce per load more than detergent B.
Detergent A uses less than 1 fluid ounce per load less than detergent B.
Answer:
Detergent A uses exactly 1 fluid ounce per load more than detergent B.
Step-by-step explanation:
We are given that Detergent A contains 48 fluid ounces and cleans 16 loads of dishes. Detergent B contains 76 fluid ounces and cleans 38 loads of dishes.
We have to compare that which detergent is accurate.
As we know that the formula for finding fluid ounce per load is given by;
Fluid ounce per load = [tex]\frac{\text{Amount of fluid ounces}}{\text{Amount of loads}}[/tex]
For detergent A;Fluid ounces = 48
Loads of dishes = 16
So, fluid ounce per load = [tex]\frac{48}{16}[/tex]
= 3 fluid ounce per load
For detergent B;
Fluid ounces = 76
Loads of dishes = 38
So, fluid ounce per load = [tex]\frac{76}{38}[/tex]
= 2 fluid ounce per load
So, we can clearly see that Detergent A uses exactly 1 fluid ounce per load more than detergent B, ie. (3 - 2) = 1 fluid ounce per load.

HELPPPPP g(a)=4a+3, h(a)=a^2+2a Find (g-h)(a)
Answer:
(g-h)(a) = -a² + 2a + 3
Step-by-step explanation:
To find (g-h)(a) , we will follow the steps below:
From the question given
g(a)=4a+3
h(a)=a²+2a
so
(g-h)(a) = g(a) - h(a)
= 4a + 3 - (a² + 2a)
= 4a + 3 - a² - 2a
= 2a + 3 - a²
= -a² + 2a + 3
(g-h)(a) = -a² + 2a + 3
A region is bounded by semicircular arcs constructed on the side of a square whose sides measure 2/\pi, as shown. What is the perimeter of this region?
Answer:
4
Step-by-step explanation:
The perimeter of the region is equal to the sum of the perimeter of the four semicircular arc. Since the semicircular arcs have the same measure, therefore:
Perimeter of region = 4 × Perimeter of semicircular arc.
The side of the square = diameter of the semicircle = 2/π.
The radius of semicircle = diameter/2 = [tex]\frac{2/\pi}{2} =\frac{1}{\pi}[/tex]
The perimeter of a semicircle = perimeter of a circle ÷ 2
[tex]Perimeter\ of \ semicircle = \frac{perimeter\ of\ circle}{2}=\frac{2\pi r}{2}=\frac{2\pi (\frac{1}{\pi} )}{2} =1\\ Perimeter\ of\ region = 4*Perimeter\ of \ semicircle=4*1=4\[/tex]

Answer:
x (children) = 58
y (students) = 66
z (adults) = 29
Step-by-step explanation:
Step 1: Write system of equations
x + y + z = 153
5x + 7y + 12z = 1100
1/2x = z
The best way to solve the systems of equations is to use an augmented matrix:
Top row: [1 1 1 | 153]
Middle row: [5 7 12 | 1100]
Bottom row: [1/2 0 -1 | 0]
And then put it in RREF form:

Step-by-step explanation:
(a)From the graph, 11 men have a waist measurement of 85cm and below.
Since the cumulative frequency is 40
Number of men who have a waist measurement of more than 85 cm
[tex]=40-11\\=29[/tex]
(b)Median
[tex]\text{Median}=\dfrac{N}{2}\\N=40\\Median=\dfrac{40}{2}=20th$ item[/tex]
Tracing 20 from the y-axis to the x-axis, the median waist measurement is 91cm.
(c)Interquartile Range
Interquartile Range = [tex]Q_3-Q_1[/tex]
[tex]Q_1=\dfrac{N}{4}=\dfrac{40}{4}=10th$ item[/tex]
From the graph, at y=10, x=84 cm
[tex]Q_3=\dfrac{3N}{4}=\dfrac{3*40}{4}=30th$ item[/tex]
From the graph, at y=30, x=97 cm
Therefore:

What is the unit rate of each point (10,2.4) (15, 3.6) (17.5, 4.2)
Answer:
0.24
Step-by-step explanation:
Given the points (10,2.4) (15, 3.6) (17.5, 4.2)
The unit rate is the slope of the line joining any of the two points.
Using points (10,2.4) and (15, 3.6)
[tex]Slope, m=\dfrac{3.6-2.4}{15-10} \\=\dfrac{1.2}{5} \\\\=\dfrac{6}{25}[/tex]
=0.24
Using points (10,2.4) and (17.5, 4.2)
[tex]Slope, m=\dfrac{4.2-2.4}{17.5-10} \\=\dfrac{1.8}{7.5} \\\\=\dfrac{6}{25}\\=0.24[/tex]
Therefore, the unit rate for each point is 0.24

If the diameter of a circle is doubled, the circumference of the new circle is..
A. 1/4 of the circumference of the original circle
B. 1/2 of the circumference of the original circle
C. The same as the circumference as the original circle
D. 2 times the circumference of the original circle
E. 4 times the circumference of the original circle
Answer:
D
Step-by-step explanation:
Let's call the original diameter x. Then, the circumference would be xπ. If the diameter is 2x, the circumference is 2xπ. 2xπ / xπ = 2 so the answer is D.
Answer:
D. 2 times the circumference of the original circle
Step-by-step explanation:
The circumference of a circle is represented by the formula C = 2(r)pi (where is r is the radius), which can also be written as C = (d)pi, where d is the diameter, (since 2r is equivalent to d). If the diameter is doubled, the original equation can be rewritten as C = 2(d)pi. Therefore, the circumference of the new circle is double the original circle.
You can plug in a sample number to further prove this point. Pretend r = 3 so d = 6. C = 6pi. Now when the diameter is doubled, d = 12 and C = 12pi which is double 6pi.
So the answer is D. 2 times the circumference of the original circle
A university would like to estimate the proportion of fans who purchase concessions at the first basketball game of the season. The basketball facility has a capacity of 3 comma 600 and is routinely sold out. It was discovered that a total of 210 fans out of a random sample of 500 purchased concessions during the game. Construct a 95% confidence interval to estimate the proportion of fans who purchased concessions during the game.
Answer:
Step-by-step explanation:
Confidence interval is written as
Sample proportion ± margin of error
Margin of error = z × √pq/n
Where
z represents the z score corresponding to the confidence level
p = sample proportion. It also means probability of success
q = probability of failure
q = 1 - p
p = x/n
Where
n represents the number of samples
x represents the number of success
From the information given,
n = 500
x = 210
p = 210/500 = 0.42
q = 1 - 0.42 = 0.58
To determine the z score, we subtract the confidence level from 100% to get α
α = 1 - 0.95 = 0.05
α/2 = 0.05/2 = 0.025
This is the area in each tail. Since we want the area in the middle, it becomes
1 - 0.025 = 0.975
The z score corresponding to the area on the z table is 1.96. Thus, the z score for a confidence level of 95% is 1.96
Therefore, the 95% confidence interval to estimate the proportion of fans who purchased concessions during the game is
0.42 ± 1.96√(0.42)(0.58)/500
= 0.42 ± 0.043

Since WX is tangent, it is a right angle
VWX is a right triangle, so we can use the Pythagorean theorem
a^2+b^2 = c^2
6^2 + 8^2 = VX ^2
36+64 = VX ^2
100 = VX ^2
Take the square root of each side
sqrt(100) = sqrt( VX ^2)
10 = VX
Answer:
10 cm
Step-by-step explanation:
Since WX is tangent to the circle V, by definition, WX ⊥ WV.
So, we've established that ΔWXV is a right triangle. This means that we can apply the Pythagorean Theorem, which states that for a triangle with legs a and b and hypotenuse c:
a² + b² = c²
Here, we have a = WV = 6 and b = WX = 8, so:
a² + b² = c²
6² + 8² = 36 + 64 = 100
c² = 100
c = √100 = 10
Therefore, VX = 10 cm.
