Answer:
y=4
Step-by-step explanation:
-2(y-7)=9y-30
Do distributive property-2y+14=9y-30
Move the terms-2y-9y=-30-14
Collect like terms-11y=-30-14
Calculate the difference-11y=-44
Divide both sides by -11y=4

Problem 10
Answer: 20 degrees
Explanation: Angle GBE = 20 is shown in the diagram which is adjacent to the angle we want. Recall that the incenter is found by constructing the angle bisectors of a triangle. The angle bisectors cut each angle in half. So angle ABG and angle GBE are the same measure.
========================================================
Problem 11
Answer: 22 degrees
Explanation: We'll use similar reasoning as above to find that angle GCA is 11 degrees. So angle BCA = (angle BCG)+(angle GCA) = 11+11 = 22.
========================================================
Problem 12
Answer: 118 degrees
Explanation: Make a copy of triangle ABC. Ignore the other line segments inside the triangle. We found so far that angle B = 20+20 = 40 degrees and angle C is 22 degrees. Solve A+B+C = 180 to get A = 118. This is the measure of angle BAC.
========================================================
Problem 13
Answer: 59
Explanation: Cut the result of problem 12 in half. We're using the same idea as problem 1. Segment AG cuts angle BAC into two equal halves.
========================================================
Problem 14
Answer: 4
Explanation: We can show that triangles GEB and GDB are congruent by the AAS congruence theorem. Note the two pairs of congruent angles, and the pair of congruent sides that are not between the angles. From there, we see the corresponding pieces GE and GD are the same length. The diagram shows GE = 4, so GD = 4 also.
========================================================
Problem 15
Answer: 11
Explanation: Same idea as problem 14. This time we focus on the corresponding congruent parts BD and BE, which are both 11 units long.
========================================================
Problem 16
Answer: sqrt(137)
Explanation: Focus on triangle GDB or triangle GEB (they're the same triangle, just one is a mirror reflection of the other). Use the pythagorean theorem with a = 4, b = 11 to find that c = sqrt(137)
========================================================
Problem 17
Answer: 4*sqrt(26)
Explanation: We'll use a similar idea as problem 14. We can prove triangles GFC and GEC are congruent by AAS. Consequently, we know that FC = EC = 20. The diagram shows EG = 4. Focus on triangle GEC. Use the pythagorean theorem to find that GC = sqrt(416) = 4*sqrt(26)

Which is a possible combination of root types for a 7th degree polynomial?
Which is a possible combination of root types for a 7th degree polynomial?
6 rational roots, 1 irrational root
3 irrational roots, 4 complex roots
2 rational roots, 2 irrational roots, 3 complex roots
7 rational roots
Given:
Degree of a polynomial is 7.
To find:
The possible combination of root types for a 7th degree polynomial.
Solution:
We know that, by complex conjugate root theorem, is a complex number is a root of a polynomial, then its conjugate is also the root of that polynomial, it means number of complex roots always an even number.
Similarly,
Irrational roots are also occurs in pairs. If [tex]1+\sqrt{2}[/tex] is a root of polynomial, then its [tex]1-\sqrt{2}[/tex] is also the root of that polynomial, it means number of irrational roots always an even number.
In options A, B and C either complex or irrational roots are odd, which is not true.
Therefore, the correct option is D.
what is the final step in the inequality -2(5-4x)<6x-4
Answer:
x < 3
Step-by-step explanation:
-2(5-4x)<6x-4
In this inequality, we are to solve for x using the steps below;
-2(5-4x)<6x-4
Expand the parentheses on the left hand side of the expression;
-10 + 8x < 6x - 4
Collect like terms to both sides;
-10 + 4 < 6x - 8x
-6 < -2x
Divide both sides by - 2; Note the sign of the inequality changes;
3 > x or x < 3

Sara has opened her own bakery, where customers can buy three chocolate chip cookies for $2.49. a. What is the unit price? b. What is the constant of proportionality, or k? c. In a complete sentence, explain what k means in the context of this problem.
Answer:
a) $0.83
b) k = 1.205
c) In the context of this problem, k means
The number of chocolate chip cookies increases as the price increases because number of chocolate chip cookie is directly proportional to its price
Step-by-step explanation:
Sara has opened her own bakery, where customers can buy three chocolate chip cookies for $2.49.
a. What is the unit price?
The unit price means the cost of 1 cookie
Hence:
3 chocolate chip cookies = $2.49
1 chocolate chip cookies = x
3x = $2.49 × 1
x = $2.49 × 1/3
x = $0.83
Hence, the unit price = $0.83
b. What is the constant of proportionality, or k?
Chocolate chip cookie ∝ Price
Chocolate chip cookie is directly proportional to the Price
C = kP
Where k is constant of proportionality
k = Chocolate chip cookie/Price
k = C/P
Hence,
k = 3/2.49
k = 1.2048192771
k = 1.205
c. In a complete sentence, explain what k means in the context of this problem.
In the context of this problem, k means
The number of chocolate chip cookies increases as the price increases because number of chocolate chip cookie is directly proportional to its price
You are making a new type of deodorant from two different mixtures the first mixture is 30% smell proof and the second mixture is 80% smell proof to make a safe make sure it needs to be 50% smell proof how much of each makes you need if you want 1000 L total
Answer:
600 L of 30% proof and 400 L of 80% proof is needed
Step-by-step explanation:
Let the amount of 30% smell proof be x while that of 80% smell proof is y
Then;
x + y = 1000 •••••(i)
Also;
30% of x + 80% of y = 50% of 1000
0.3x + 0.8y = 500 •••••(ii)
From i, x = 1000 - y
Put this into ii
0.3(1000-y) + 0.8y = 500
300 - 0.3y + 0.8y = 500
0.5y = 500-300
0.5y = 200
y = 200/0.5
y = 400 L
But x = 1000 - y
x = 1000 - 400 = 600 L

Step-by-step explanation:
Manny is buying new clothes for school. He buys three shirts for $14.95 each and a tie for $12. Everything in the store is on sale for 15% off. What is Manny's total cost?
Given:
Cost of each shirt = $14.95
Cost of a tie = $12
Discount on Sale = 15% off
Manny buys three shirts and a tie.
To find:
The Manny's total cost.
Solution:
We have,
Cost of 1 shirt = $14.95
Cost of 3 shirt = 3 × $14.95
= $44.85
Cost of a tie = $12
Total cost before discount = Cost of 3 shirt + Cost of a tie
= $44.85 + $12
= $56.85
Everything in the store is on sale for 15% off. So,
[tex]\text{Manny's total cost}=56.85-\dfrac{15}{100}\times 56.85[/tex]
[tex]\text{Manny's total cost}=56.85-0.15\times 56.85[/tex]
[tex]\text{Manny's total cost}=56.85-8.5275[/tex]
[tex]\text{Manny's total cost}=48.3225[/tex]
Therefore, the Manny's total cost is $48.3225.

Step-by-step explanation:
Given the mean is 19, find the value of x. -3, 10, 22, x, 28
Answer:
The value of x = 38
Step-by-step explanation:
As we know that
The mean of a data set is the sum of the terms divided by the total number of terms.
Using math notation we have:
Mean = (Sum of terms) ÷ (Number of terms)
As
Number of terms = 5Mean = 19Sum of terms = -3 + 10 + 22 + x + 28so mean the equation becomes
Mean = (Sum of terms) ÷ (Number of terms)
19 = (-3+10+22+x+28) ÷ 5
19 × 5 = -3+10+22+x+28
95 = x + 57
x = 95 - 57
= 38
Therefore, the value of x = 38
Dermot bakes 420 cakes.
He bakes only vanilla cakes, banana cakes and lemon cakes. 120 of the cakes are vanilla cakes.
35% of the cakes are banana cakes.
Work out the number of lemon cakes Dermot bakes. PLEASEE I NEED NOW
Answer:
Step-by-step explanation:
lemon cakes:105
420-120=300
35% of 300:
35 divided by 100*300=105
Number of lemon cakes Dermot bakes are 153.
What is percentage?"A percentage is a ratio of a number to 100. The symbol % is used to indicate a percent."
According to the problem
Number of vanilla cakes = 120
Total number of cakes = 420
Banana cakes = 35 % (35 percentage) of total cakes
= 420 × 35%
= 420 × [tex]\frac{35}{100}[/tex]
= 147
So the lemon cakes are = Total cakes - banana cakes - vanilla cakes
= 420 - 147 - 120
= 153
Hence, number of lemon cakes Dermot bakes are 153.
