Your end goal is to have $6000 total in 12 months. since you have$2400 already you can subtract that from 6000 leaving you with $3600 over the course of 12 months. since you already put$150 in a month over the course of 12 months you would have $1800 which is only half of the goal of$3600. in order for you to put in $3600 you would have to put an additional 150 in your savings along with your regular 150 making the answer b. ANSWERED AT 28/01/2020 - 12:41 AM QUESTION POSTED AT 28/01/2020 - 12:41 AM ### At the beginning of the week, Naveen has 87 trading cards. On Monday, he gets 9 more. On Tuesday, he gives 16 away. On Wednesday, he is given 3 by a friend. On Thursday, he sells all of his cards to a collector. The collector pays him a rate of c for every card that Naveen has. If Naveen earns$124.50 from the sale, what is c, the rate that the collector pays for each card

Answer: The collector pays 1.5 for each card.

Step-by-step explanation:

Hi, to solve this problem we have to calculate the total number of cards that Naveen has on Thursday.

So:

• Cards at the beginning of the week: 87
• Monday: he gets 9
• Tuesday: he gives 16 (-16)
• Wednesday:  he gets 3

We have to sum the cards he gets (9,13) and subtract the ones that he gives away (16).

Mathematically speaking:

• 87 +9- 16+ 3 = 83 cards

Now that we have the total number of cards, we have to write an equation with the rest of the information:

• Collector pays him a rate of c for every card
• Naveen earns $124.50 Finally, we have to multiply the "c" (rate) by the number of cards that Naveen has, and this expression equals$124.50(earnings).

• 83 c = 124.50

Solving:

c = 124.50 / 83

c = 1.5

The collector pays 1.5 for each card.

How much extra hours did he spent doing his homework between last week and this week:
11-10= 1 hour
Extra hour over original hour x 100% will be the percentage of extra time he did his homework:
1/10 x 100% = 10%
Therefore, he is not correct.

### Select the equation in which the graph of the line has a negative slope and the y-intercept equals 10. A.10x+5y=-25 B.5x-10y=-12 C.20x+5y=50 D.2x+6y=10

That would be C.

20x + 5y = 50
5y = - 20x + 50
y = -20/5x + 50/5
y = - 4x + 10
now in y = mx + b form. the m represents ur slope and the b represents ur y intercept. So here, u have a slope of -4 and a y intercept of 10.

### If side a measures 90 feet and side b measures 120 feet, how many feet of flowers will be planted along side c, the hypotenuse of the triangle? Show your work and explain your reasoning.

A^2 + b^2 = c^2...a and b are the legs and c is the hypotenuse
90^2 + 120^2 = c^2
8100 + 14400 = c^2
22500 = c^2.....take the sq rt of both sides...this gets rid of the ^2
sq rt 22500 = c
150 = c

so side a = 90 ft, side b = 120 ft, and side c = 150 ft

this is called the pythagorean theorem and it only works on right triangles

### For the given quadratic equation convert into vertex form, find the vertex, and find the value for x = 6. Show your work.

Vertex form is just completeing th square

y=-2x^2+2x+2
first isolate the x terms
y=(-2x^2+2x)+2
undistribute the coefieicne infont of x^2 term
y=-2(x^2-x)+2
take 1/2 of -1 and square it (-1/2 sqared=1/4)
y=-2(x^2-x+1/4-1/4)+2
complete the square
y=-2((x-1/2)^2)-1/4)+2
y=-2(x-1/2)^2+1/2+2
y=-2(x-1/2)^2+2.5

in form
y=a(x-h)^2+k
vertex=(h,k)
y=-2(x-1/2)^2+2.5
vertex is (0.5,2.5)

for x=6
input 6 for x and evaluate
y=-2(6)^2+2(6)+2
y=-2(36)+12+2
y=-72+14
y=-58

for x=6, the value is -58

the vertex form is
y=-2(x-1/2)^2+2.5
vetex is (0.5,2.5)

Which sample is likely to yield the most biased results? every tenth boy on the school’s phone list every member of the boys’ basketball team every boy in a randomly selected ninth-, tenth-, eleventh-, and twelfth-grade gym class every fifth boy who walks through the front doors of the school in the morning

If the shoe size of every member of the boys’ basketball team is used as the sample, the result will be strongly biased towards large shoe sizes. The other ways of choosing a sample will give much better distributions over a range of sizes.

### Wayne and Winston are scuba diving and are ascending to the surface. The function y = 30x − 105 represents Wayne’s elevation in feet in terms of the time in minutes he ascends. The table represents Winston’s elevation in feet in terms of the time in minutes he ascends. Assume that Wayne and Winston both ascend at a constant rate.

The function that represents Wayne´s elevation:
y = 30 x - 105
The function that represents Winston´s elevation:
- 100 = 0 m + b
b = -100
-16 = 3m - 100
3 m = 84
m = 84 : 3 = 28
y = 28 x - 100
Surface level: y = 0
Wayne:
0 = 30 x - 105
x = 3.5 minutes
Winston:
0 = 28 x - 100
x = 3.57 minutes
If they both ascend at the same rate, Wayne will be first to the surface.

### Which graphThe Pythagorean theorem states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse by the formula a2 + b2 = c2. If a is a rational number and b is a rational number, why could c be an irrational number? represents the solution set of the compound inequality mc011-1.jpg?

Because even though 'a' and 'b' are rational, and their squares are
also rational, that doesn't guarantee that the sum of their squares
has a rational square root.

Examples:

1 and 2
Sum of squares = 5
√5 is irrational

2 and 3
Sum of squares = 13
√13 is irrational

4 and 5
Sum of squares is 41
√41 is irrational

'c' is rational only when 'a', 'b', and 'c' form a . . . . . wait for it . . . . .
a 'Pythagorean triple'.

Examples:

3 and 4
Sum of squares is 25
√25 = 5 is rational                yay

5 and 12
Sum of squares is 169
√169 = 13 is rational            yay
