1.Samantha sells ostrich eggs for $2 each and goose eggs for 0.50. For every dollar she earns, she spends $0.10 on feed. If she sells 5 ostrich eggs and 20 goose eggs, how much money does she have left after buying feeds
Answer:
$18
Step-by-step explanation:
Sales price of each ostrich egg = $2
Sales price of each goose egg = $0.50
Amount spent after every dollar earned = $0.10
Number of ostrich eggs sold = 5
Number of goose eggs sold = 20
To find:
Total money left after the feeds are bought?
Solution:
First of all, let us find the total money earned by Samantha.
Money earned by selling ostrich eggs = [tex]2\times 5[/tex] = $10
Money earned by selling goose eggs = [tex]20\times 0.50[/tex] = $10
Total money earned by selling both the eggs = 10+10 = $20
Money spent on feeding on every $1 = $0.10
Money spent on feeding on every $20 = 0.10 [tex]\times[/tex] 20 = $2
Total money left after buying feeds = $20 - $2 = $18

Is there a solution to 8,-5
Answer:
The solution is x = 8.
Step-by-step explanation:
8x-9+53=180 solve for x
Answer:
x=17
Step-by-step explanation:
1: Simplify both sides of the equation.
8x−9+53=180
8x+−9+53=180
(8x)+(−9+53)=180(Combine Like Terms)
8x+44=180
8x+44=180
2: Subtract 44 from both sides.
8x+44−44=180−44
8x=136
3: Divide both sides by 8.
(8x=136 )/8
x=17

There is a bag with only red marbles and blue marbles.
The probability of randomly choosing a red marble is 2/7
There are 16 red marbles in the bag and each is equally likely to be chosen.
Work out how many marbles in total there must be.
Answer: 56
Step-by-step explanation:
Given that :
Marbles in bag are only red and blue ;
Probability of randomly choosing a red = 2/7
Number of red marbles in bag = 16
The total Number of marbles =?
P(choosing a red marble) = required outcome / Total possible outcomes
Required outcome = number of red marbles
Total possible outcomes = total number of blue and red marbles
Total number of blue and red marbles = x
P(choosing a red marble) = required outcome / Total possible outcomes
2/7 = 16 / x
Cross multiply
2x = 16 * 7
2x = 112
x = 112 / 2
x = 56 marbles
Total number of marbles = 56

If the height of Mount Everest is about 8.8 time 10 to the third power meters and the height of the Empire State Building is about 3.8 times 10 to the second power meters which of these statements is a true
Answer: C. Mount Everest is about 23 times as tall as the Empire State Building
Step-by-step explanation:
The options are:
A.There is no way to compare these heights
B.Mount Everest is about 40 times as tall as the Empire State Building
C.Mount Everest is about 23 times as tall as the Empire State Building
D.The Empire State Building is about 23 times as tall as Mount Everest
Mount Everest = 8.8×10^3 meters = 8800 meters
Empire State Building = 3.8×10^2 = 380 meters
Mount Everest is (8800 / 23) = 33 times as tall as the Empire State Building. Therefore, the correct option is C.
Answer:
Mount Everest is about 23 times as tall as the Empire State Building. Hope that helps!

Answer:
The correct choice is:
-2 to the 4th power is positive 16.
Option C is correct.
Step-by-step explanation:
We need to find mistake make in work below:
[tex](-2x^4)^4=-16x^{16}[/tex]
The mistake here is when we have even power, the negative sign gets positive i.e [tex](-a)^m=a^m[/tex] if m is even
so, in our case it would be:
[tex](-2x^4)^4=16x^{16}[/tex]
The correct choice is:
-2 to the 4th power is positive 16.
Option C is correct.

Find the 52nd term of the arithmetic sequence-8, -12, -16,...
Answer:
-212
Step-by-step explanation:
This question seems to be incrementing by steps of -4, starting at -8. To get the 52'nd term, we can simply start at the first term and add that -4 51 more times.
Assuming that negative eight is the first term then, we get:
-8 - 4 * 51
= -8 - 204
= -212
The 52nd term of the sequence will be -212.
What is a sequence?A sequence of events or things is a number of events or things that come one after another in a particular order.
Given a sequence, -8, -12, -16,...
nth term of a sequence is given by
an = a + (n-1)*d
a(-212) = -8 + (52-1)*-4
a(-212) = -8-204
a(-212) = -212
Hence, The 52nd term of the sequence will be -212.

An angle's measure is 43 less than 6 times the measure of its
complement. Find the measure of both angles,
Step-by-step explanation:
A = 6(90-A)-43 Simplify and solve for A.
A = 540-6A-43
A = 497-6A Add 6A to both sides.
7A = 497 Divide both sides by 7.
A = 71 degrees
The complement of A = 90-A = 09-71 = 19

Steve Conway wants his team to win more than 57 games this year. His team has already won 2 games this season and there are 5 more months to play. Based on his goal, how many games must his team win per month? Write answer as an inequality.
Answer:
11
Explanation:
Because 57 minus 2 games already equals 55, so 55 games divided by 5 months equals 11, so 11 games each month will get u to 57.
The number of games must his team win per month will be;
⇒ x > 11
What is Inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
Steve Conway wants his team to win more than 57 games this year.
And, His team has already won 2 games this season and there are 5 more months to play.
Now,
Let number of games must his team win per month = x
So, We can formulate the inequality as;
⇒ 5x + 2 > 57
Solve for x as;
⇒ 5x > 57 - 2
⇒ 5x > 55
⇒ x > 11
Thus, The number of games must his team win per month will be;
⇒ x > 11

The measure of ∠BCD is 145°. The measure of ∠ABC is 65°.
What is measure of ∠BAC?
115°
35°
80°
145°
Answer:
m∠BAC = 80°Step-by-step explanation:
m∠BCD = 145° ⇒ m∠BCA = 180° - 145° = 35°
From ΔABC:
m∠ABC + m∠BCA + m∠BAC = 180°
65° + 35° + m∠BAC = 180°
m∠BAC = 180° - 100°
m∠BAC = 80°

find all values of c in the open interval (a, b) such that f'(c)=(f(b)-f(a))/(b-a)
f(x)=√(4-x), [-5,4]
================================================
Work Shown:
Compute the function value at the endpoints
[tex]f(x) = \sqrt{4-x}\\\\f(-5) = \sqrt{4-(-5)} = 3\\\\f(4) = \sqrt{4-4} = 0\\\\[/tex]
With a = -5 and b = 4, we have
[tex]f'(c) = \frac{f(b)-f(a)}{b-a}\\\\f'(c) = \frac{f(4)-f(-5)}{4-(-5)}\\\\f'(c) = \frac{0-3}{9}\\\\f'(c) = -\frac{1}{3}\\\\[/tex]
So,
[tex]f(x) = \sqrt{4-x}\\\\f'(x) = -\frac{1}{2\sqrt{4-x}}\\\\f'(c) = -\frac{1}{3}\\\\-\frac{1}{2\sqrt{4-c}} = -\frac{1}{3}\\\\[/tex]
Use algebra to solve for c
[tex]-\frac{1}{2\sqrt{4-c}} = -\frac{1}{3}\\\\\frac{1}{2\sqrt{4-c}} = \frac{1}{3}\\\\3 = 2\sqrt{4-c}\\\\2\sqrt{4-c} = 3\\\\\sqrt{4-c} = \frac{3}{2}\\\\4-c = \frac{9}{4}\\\\c = 4-\frac{9}{4}\\\\c = \frac{16-9}{4}\\\\c = \frac{7}{4}\\\\[/tex]
