value of x
(8x+7)°=(9x-4)°
vertically opposite angles are equal
8x°-9x°=-4°-7°
-x°=-11°
divide both sides by -1° don't counsel negative
x=11
value of Y
5y°=(7y-34)°
vertically opposite angles are equal
5y°-7y°=34°
-2y°=34°
divide both sides by-2° don't counsel negative
y=17

Answer:
part A: D Marina
part B: A Anna
Step-by-step explanation:
If you're not that familiar with these fractions and their equivalents, you can always compare them using their least common denominator: 24.
Joseph: 1/3 = 8/24
Anna: 1/6 = 4/24
Elvin: 3/12 = 6/24
Theo: 1/4 = 6/24
Marina: 5/8 = 15/24
Then the ordering from least-to-greatest is ...
Anna, {Elvin, Theo}, Joseph, Marina
Part A
Marina reached the greatest fraction of the goal.
Part B
Anna reached the least fraction of the goal.
Can we conclude that two similar figures can also be congruent figures? Explain.
Answers
Answer:
In similar figures, the angles are congruent, even if the sides are not. Notice that one angle in each pair of figures corresponds to an angle in the other figure. They have the same shape but not the same size
A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore. Suppose that a storm is in progress with a severe storm class rating. Let us say that we want to set up a statistical test to see if the wave action (i.e., height) is dying down. The next 10 waves have an average wave height is 16 feet with a SD of .6 ft. If you wanted to test the hypothesis that the waves are dying down, what would you use for the alternate hypothesis
Answers
Answer:
The alternate hypothesis is:
[tex]H_{a} < 16[/tex]
Step-by-step explanation:
There are two types of hypothesis. The null hypothesis and the alternate hypothesis. The null hypothesis is that the mean found is equal to the expected value. The alternate hypothesis is a question about this expected value(different, more, less)
A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore.
This means that the null hypothesis is [tex]H_{0} = 16.4[/tex]
Let us say that we want to set up a statistical test to see if the wave action (i.e., height) is dying down. If you wanted to test the hypothesis that the waves are dying down, what would you use for the alternate hypothesis
Dying down means lower average peak, that is, lower than the average of 16.4. This means that the alternate hypothesis is:
[tex]H_{a} < 16[/tex]

Answers
Answer:
16
Step-by-step explanation:
10÷5/8=16
Answer:
16
Step-by-step explanation:
To solve problems where a fraction is being divided, we use a reciprocal of the fraction, which means that you flip the fraction upside down and multiply by the other number. So for this problem, the opposite of 5/8 is 8/5, so we need to multiply that by 10.
10*8/5
80/5

Step-by-step explanation:
So the little arrows on the lines means they are equal to each other so if you look, A to D and B to C have only one arrow meaning those two lines are the same lines
and A to B and D to C have two arrows meaning those two lines are the same
so that means if A to B is 9 and it's equal to the line D to C, then D to C is also 9
Hopefully this wasn't too confusing
Answer:
mCD = 9
Step-by-step explanation:
Because this polygon has opposite parallel sides, meaning each side across from each other are parallel, we know that this is a parallelogram. So:
AB ║ DC
BC ║ AD
Because this is a parallelogram, we know that, from the properties parallelograms, opposite sides of a parallelogram are congruent. This means that AB ≅ DC.
This also means that because AB = 9 and AB = DC, DC = 9.
Here's a mini two-column proof:
Statements → Reasons
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
mAB = 9 → Given
AB ║ DC, BC ║ AD → Given
ABCD is a parallelogram → Definition of a Parallelogram
AB ≅ DC → Opposite sides of a parallelogram are congruent.
mAB = mDC → Definition of Congruent Segments
9 = mDC → Substitution Property of Equality
mCD = mDC → Reflexive Property of Equality
mCD = 9 → Substitution Property of Equality

Step-by-step explanation:
We are going to change both number so they have the same denominators.
1/4x3/3= 3/12
2/3x4/4=8/12
Once we changed the number we are going to subtract the numbers.
8/12-3/12=5/12
We can't simplify 5/12 so the answer is 5/12.

f(x) - g(x) = 7x^4+2x^2-3x-10
Step-by-step explanation:
f(x) = 10x^4 + 2x^2 +1
g(x) = 3x^4 +3x +11
f(x) - g(x) = 10x^4 + 2x^2 +1 - ( 3x^4 +3x +11)
Distribute the minus sign
f(x) - g(x) = 10x^4 + 2x^2 +1 - 3x^4 -3x -11
Combine like terms
f(x) - g(x) = 7x^4+2x^2-3x-10
