Answers
Answer: See Below
Step-by-step explanation:
there is a ton of information here to get through
<a is 34 (half of 68)
<C is 56
triangle YRC is iscocles, YR and RX are both radius, so they are equal. So the base angles must be equal as well. we know that the central angle is 68, because arc YX is 68. to find the measure of angle C use the equation 2x+68=180 (2 of the same angle (x) + 68 makes all the angles in the triangle. 2x=180-68 2x=112x=56Skip E until the end
<G is 84
<G and the angle that is 96 make a linear pair <G + 96=180<G=84Arc YS is 112
Arc YS is = <Rfind <R<R and the angle across from ARC YX are a linear pair<YRX is 68<R+68=180<R is 112<D and F are 42
<D and <F are the base angles of an isosceles triangle (2 sides are the radius again)the central angle in this case is 962x+96=1802x=84x= 42so both D and F are 42now <E is 96
measure of an angle outside the circle with 2 rays touching the circle is the measure of the larger arc of the circle minus the smaller arc divided by 2the measure of the smaller arc is the same as <Gsmaller arc is 84the larger arc is 360-84the larger arc is 276276-84= 192divide by 2 to get <E192/2=96Help me get these please

Choose all the weights that are equal to 1 ton 200 pounds.
A.
35,000 ounces
B.
1,200 pounds
C.
2,200 pounds
D.
1,200 pounds 100 ounces
E.
1 ton 100 pounds 1,600 ounces please answer this
Answers
Answer:
C. and E. i did the test
Step-by-step explanation:
The only options that are equal to 1 ton 200 pounds are C and E.
What is unit conversion?It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.
We are given that;
1 ton 200 pounds.
Now,
We can compare this value with the given options and see which ones are equal to it. We can use the conversion factors from the search results34 to convert ounces to pounds. We get:
A. 35,000 ounces = 35,000 / 16 pounds 35,000 ounces = 2,187.5 pounds This is not equal to 2,200 pounds.
B. 1,200 pounds = 1,200 pounds This is not equal to 2,200 pounds.
C. 2,200 pounds = 2,200 pounds This is equal to 2,200 pounds.
D. 1,200 pounds 100 ounces = (1,200 + (100 / 16)) pounds 1,200 pounds 100 ounces = (1,200 + 6.25) pounds 1,200 pounds 100 ounces = 1,206.25 pounds This is not equal to 2,200 pounds.
E. 1 ton 100 pounds 1,600 ounces = ((1 x 2,000) + (100 + (1,600 / 16))) pounds 1 ton 100 pounds 1,600 ounces = (2,000 + (100 + 100)) pounds 1 ton 100 pounds 1,600 ounces = (2,000 + 200) pounds 1 ton 100 pounds 1,600 ounces = 2,200 pounds This is equal to 2,200 pounds.
Therefore, by the conversion the answer will be 1 ton 200 pounds are C and E.

2. 176.25cm²
3. 33.75ft²
Step-by-step explanation:
Area triangle = (1/2)(base)(height)
1)
total area = 2(area small triangle) + 2(area big triangle)
= 2(0.5(8)(9))+2(0.5(8)(11))
=72+88=160cm²
2)
total area = 2(area small triangle) + 2(area big triangle)
= 2(0.5(7.5)(7.5))+2(0.5(7.5)(16))
= 56.25 + 120 = 176.25cm²
3)
total area = 2(area small triangle) + 2(area big triangle)
= 2(0.5(4.5)(2.5))+2(0.5(4.5)(5))
= 11.25+22.5 = 33.75ft²

1) you deposit $2,300 in a bank account. find the balance after 5 years for each of the following situations: is) the account pays 2.5% annual interest compounded monthly.
Answers
Answer:
Well, After 5 years No interest you'd still have only 2,300 dollars in the bank.
But 5 years with interest you'd have 5750$ in the bank.
Step-by-step explanation:
With no interest, their is nothing added to your bank account, if you don't take anything away from it either then you'd still have the exact same amount.
With 2.5% monthly interest you'd get 3250$ because...5years * 12 months = 60 months...60 months * 2.5% = 150%...2,300$ + 150% = 5750$.

Answer:
F- test
Step-by-step explanation:
Testing the hypothesis about the equality of k (k>2) population means
Test statistic F is used to find the whether there is no difference in the average age of each group.
Test statistic to be used
F= Between Mean Square/ Within Mean Square
F= s1²/s2² where s1 and s2 are independent unbiased estimates of the variance and their values do not differ greatly.
Which have v1= k-1 and v2= n-k degrees of freedom
The analysis of variance F -t est is always a one tailed test with rejection region located in the right tail of the F- distribution.
