find the area of the compound shape. use 3.14 for pi.
1. 26.1cm square 2
2. 125.1cm square 2
3. 68.5cm square 2
4. 28.3cm square 2
Answer:
1. 26.1 cm²
Step-by-step explanation:
For area of semi circle
diameter = 6cm
radius = 6/2 = 3cm
Area of semi circle = 1/2 x pi x r²
= 1/2 x 3.14 x 3²
= 1.57 x 9
= 14.13 cm²
For area of rectangle,
length = 6cm
breadth = 2cm
Area = length x breadth
= 6 x 2
= 12cm²
Area of compound shape = 14.13 + 12
= 26.13 cm²

Answer:
D) 96 is closest
Step-by-step explanation:
12x7=84
1/2(8)(4)=16
84+16=100
A = 30
B = 45
C = 160
D = 96
find the value of M in the following equation 7=m*12
Step-by-step explanation:
7=m*12
divide the equation by 12
7/12=12m/12
7/12=m
if you meant to type 7=m^12
then the answer for m is 7^(1/12)
which is 1.1760
Hope that helps :)
Kisi samantar shreni me pratham 6 pado ka yog 42 hai iske 10 we pad tatha 30 we pad me anupat 1:3 ka hai is samtar shereni ka pratham tatha 13 pad gyat kare
Answer:
समांतर श्रेणी का प्रथम पद a = 2
[tex] t_{13}= 26[/tex]
Step-by-step explanation:
माना समांतर श्रेणी का प्रथम पद a और सामन्य अन्तर d है.
इसलिए..
[tex] S_6 = 42....(given) [/tex]
[tex]\therefore \frac{6}{2}\{2a + (6-1)d\}= 42 [/tex]
[tex]\therefore 3\{2a + 5d\}= 42 [/tex]
[tex]\therefore \{2a + 5d\}= \frac{42}{3} [/tex]
[tex]\therefore 2a + 5d=14...... (1)[/tex]
[tex] t_{10} : t_{30}= 1 : 3.....(given) [/tex]
[tex] \therefore \frac{t_{10}}{t_{30}} = \frac{1}{3} [/tex]
[tex] \therefore \frac{a +9d}{a+29d} = \frac{1}{3} [/tex]
[tex] 3(a + 9d) = a + 29d[/tex]
[tex] 3a + 27d = a + 29d[/tex]
[tex] 3a - a = 29d - 27d [/tex]
[tex] 2a= 2d [/tex]
[tex] a= d...... (2)[/tex]
समीकरण (1) और (2) से:
[tex]\therefore 2a + 5a=14[/tex]
[tex]\therefore 7a=14[/tex]
[tex]\therefore a=\frac{14}{7}[/tex]
[tex]\therefore a=2[/tex]
समांतर श्रेणी का प्रथम पद a = 2
a = d = 2... (समीकरण 2 से)
[tex] t_{13}= 2 + (13-1)2[/tex]
[tex] t_{13}= 2 + 12\times 2[/tex]
[tex] t_{13}= 2 + 24[/tex]
[tex] t_{13}= 26[/tex]

What is the value of x in 5x = 35? *
Answer:
7
Step-by-step explanation:
The thickness of the backfat in pigs is used in evaluating the quality of their flesh for consumption. To compare the backfat thickness of pigs raised on two different diets, an animal researcher randomly sampled a group of pigs raised on Diet 1 and another group raised on Diet 2:
Sample Mean Sample SD Sample Size
Diet 1 3.63 cm 0.29 cm 18
Diet 2 3.37 cm 0.25 cm 18
POOLED SE 0.09
A) After confirming all relevant assumptions, you want to test if the mean backfat thicknesses of the pigs raised on these two diets differs. What is the absolute value of the test statistic?
B) If the critical value for this test is 2.032 (confirm that it is), what would be an appropriate conclusion for this test?
A. An conclusion is not warranted for this test
B. This data provides evidence that mean backfat thickness of pigs on Diet 1 is different from pigs on Diet 2 (p<.05)
C. This data provides no evidence that mean backfat thickness of pigs on Diet 1 is different from pigs on Diet 2 (p<.05)
D. This data provides evidence that diet is independent of backfat thickness (p<.05)
E. There is no evidence that diet is independent of backfat thickness (p>.05)
Answer:
A) The test statistic is approximately 7.5056
B) E. There is no evidence that diet is independent of backfat thickness
Step-by-step explanation:
The given data are;
The sample mean for pigs raised on Diet 1, [tex]\overline x_1[/tex] = 3.63 cm
The sample SD for pigs raised on Diet 1, s₁ = 0.29 cm
The number of pigs in the sample for pigs raised on Diet 1, n₁ = 18
The sample mean for pigs raised on Diet 2, [tex]\overline x_2[/tex] = 3.37 m
The sample SD for pigs raised on Diet 2, s₂ = 0.25 cm
The number of pigs in the sample for pigs raised on Diet 2, n₂ = 18
The pooled SE = 0.09
A) The test statistic is given by the following formula;
[tex]t=\dfrac{(\bar{x}_{1}-\bar{x}_{2})}{\sqrt{\dfrac{s_{1}^{2} }{n_{1}}-\dfrac{s _{2}^{2}}{n_{2}}}}[/tex]
Therefore, we have;
[tex]t=\dfrac{(3.63-3.37)}{\sqrt{\dfrac{0.29^{2} }{18}-\dfrac{0.25^{2}}{18}}} \approx 7.5056[/tex]
The test statistic, t ≈ 7.5056
B) The degrees of freedom, df = n₁ - 1 = 18 - 1 = 17
At a confidence level of 95%, the critical value is 2.11
Given that the value of the test statistics tic if larger than the critical value, the null hypothesis is rejected and there is a difference in the backfat of the pigs on different diet
Therefore, there is no evidence that diet is independent of backfat thickness

A Carpenter has a board that measures 6 feet x 4 feet. a small rectangle measuring 1 foot x 1 foot is cut out of the middle how much area is left?
What is the value of the expression
3+(2+8)^2+4*(1/2)^4
Answer:
Use photo math, it will explain it all
First here's the expression written out a little clearer
[tex]3+(2+8)^2+4*(\frac{1}{2} )^4[/tex]
Parentheses: (2+8) = (10).
Exponents: 10^2 is 100, and [tex](\frac{1}{2} )^4[/tex] is [tex]\frac{1}{2} \cdot \frac{1}{2} \cdot \frac{1}{2} \cdot\frac{1}{2} =[/tex] [tex]\frac{1}{16}[/tex]
Multiplication and division: 4 * 1/16 is [tex]\frac{4}{16}[/tex] or [tex]\frac{1}{4}[/tex] simplified
Addition and subtraction: Go left to right. 3 + 100 + [tex]\frac{1}{4}[/tex] = 103.25 (final answer)
Given f(x)= 3|2x-4|-8
find f(-3)=
Hi there!
[tex]\large\boxed{f(-3) =22 }}[/tex]
Find f(-3) by substituting in -3 for x:
f(x) = 3|2x - 4| - 8
f(-3) = 3|2(-3) - 4| - 8
Simplify:
f(-3) = 3|-6 - 4| - 8
f(-3) = 3|-10| - 8
f(-3) = 3(10) - 8 = 22
Is it a right triangle please help!
Answer:
no
Step-by-step explanation:
Hello There!
We can figure out if the given side lengths form a right triangle using the Pythagorean Theorem
The Pythagorean Theorem states that the hypotenuse (longest side) squared equal to sum of the two legs squared
so if it is a right triangle then
[tex]74^2=71^+24^2[/tex]
[tex]74^2=5476\\71^2=5041\\24^2=576\\5041+576=5617\\5476\neq 5617[/tex]
5617 is not equal to 5476 therefore the given side lengths do not form a right triangle

What is equivalent to 4,000 centimeters? A. 4 meters B.40 meters C.400 meters D. 40,000 meters
Answer:
B. 40 meters
Step-by-step explanation:
there are 100 cm in a meter
we can divide 4,000 by 100 to see how many meters are equivalent to 4,000 cm.
4,000/100 = 40
Therefore, the answer is B. 40 meters

5x + (1x+6)= 78
BARDZO POTRZEBUJĘ
Answer: x = 12
Step-by-step explanation:
1. add 5x + 1x which will equal 6x so now your equation is: 6x + 6 = 78
2. subtract 6 from 78 to get 72: 6x = 72
3. divide 72 by 6x to get your answer 12
Answer:
x = 12
Step-by-step explanation:
6x + 6 = 78
6x = 78 - 6
6x = 72
x = 72 / 6
x = 12
