The formula for simple interest is A = P(1 + rt) where P is the Principal (money you start with),R is the rate/percent and T is time. A = 2000(1 + .07(5)) A = 2000(1 + .35) A = 2000 (1.35) A = 700 The interest he paid should be $700.
They look correct to me!
2 + 3 + 4 + 5 + 6 = 20 (2 + 3 + 4 + 5 + 6)/5 = 4 4:20, when simplified, is 1:5 5 + 6 + 7 + 8 + 9 = 35 (5 + 6 + 7 + 8 + 9)/5 = 7 7:35 = 1:5 300 + 301 + 302 + 303 + 304 = 1510 (300 + 301 + 302 + 303 + 304)/5 = 302 302:1510 = 1:5 I promise you, the ratio will
L = 1 W = 3 2(1) + 2(3) 2 + 6 8
Say a b c d e are 1 2 3 4 5. 1+2+3+4+5= 15 (1+2+3+4+5)/5= 3 ratio is 3:15, or 1:5 try this with any set of numbers and it will always work
Y = 1500 - 63x Create a table: 1500 - 63(0) = 1500 1500 - 63(1) = 1437 1500 - 63(2) = 1374 1500 - 63(3) = 1311 Turn them into ordered pair: (0, 1500) (1, 1437) (2, 1374) (3, 1311) Graph these points starting at the origin and go up infinitely (arrow on one
a) Y = 7.5x b) slope = 7.5 = cost per guest c) 7.5(10) = $75
Many aspects of different cultures came together through trade, which led to Greek architecture being spread, similarities in politics, and the spread of philosophical tradition.
There are 21 students in each of the other 6 groups.
Pressure is the continuous physical force exerted on or against an object by something in contact with it. There are 6563.78979 mmHg in 875.1 kilopascals.
The formula for direct variation, which is what is indicated in the problem, is P = sqrt(q) x A. A is a nonzero value, and finding its value will help create a function. 8 = sqrt(25) x A. Solve this and you will find the value of A. Then plug that value of
i believe you are correct. the only thing you can do here is replace 2 for x.
1600 - 760 840 ----------- = --- = 42 60 - 40 20 so m = 42
What you are doing is to the negative power. 4^3 is 64, not 1/64. however,2^-2 is 1/4 because it is a negative power. 10 + 4^3 x 2^-2 10 + 64 x 1/4 10 + 16 26 Just remember, a positive exponent is integer x integer as many times as the number indicated by
the easiest way to do this is to divide the fractions. first turn 2 1/2 into an improper fraction, 5/4. Then find the reciprocal of 2/3. Finding the reciprocal is just flipping 2/3 upsidown and multiplying instead of dividing. 2 1/2 divided by 2/3 5/2
the word "or" itself is a transition
I need to know the context in which you are putting this word in. Tell me the sentence
sorry, 18000 / 9 = ____
total revenue divided by # of months equals monthly revenue. 1800 / 9 = ____
you need a common denominator. you can use 25 because it is a multiple of 5. To turn the denominator, which is 5, into 25 you have to multiply it with 5. however, then you must also multiply the numerator: 2/5 x 5/5 = 10/25 10/25 + 11/25 = ____
-5y = x-15 (-5y)/-5 = (x)/-5 - (15)/-5 y = -x/5 - -3 y = -x/5 + 3 {this can also be written -1/5(x) + 3}
-4y=3x+20 divide all the numbers by -4 y= -3/4x - 5 you are correct
6 - a + 4 - 12a - 11 6 - 11 + 4 - a - 12a -1 - 13a
The equation of a line is made up of 4 parts: the y intercept, the slope, y,and x. To find the slope, follow the formula y2-y1/x2-x1. 7-3/4-5 = 4/-1 = -4. Choose either of the ordered pairs to be your x and y. Now you have 3 = -4(5) + b. Solve for b by
20 + 4x
1 nickel is 1.95 mm thick 3 + 2 + 1 = 6 6 * 1.95 = ______ mm
I know from general knowledge that oxygen has a double covalent bond, so i think A & D are 2 of the answers. Of course, I only know so much, so I could be completely wrong...
The opposite of n would be the value of n with an opposite sign. If n was -3, then the opposite of n would be 3. If n was 3, then the opposite of n would be -3. Absolute value n would have a positive sign no matter what. If n was -3, absolute value n would
Finding a square root is finding what times what equals that number. Finding a cube root is finding what times what times what equals that number. For example, the square root of 64 is 8, because 8 x 8 = 64. However, the cube root of 64 is 4, because 4 x 4
First you need a least common denominator, which is the smallest number that is a multiple of both 5 and 6. The LCM here is 30. Now let's do this one fraction at a time. In the first fraction, 4/5, we need the denominator to become 30. You can get 30 by
Once he eats half of the pizza, there is one half left. To find one third of one half, you have to multiply the fractions. 1/2 x 1/3 multiply the numerators together, then the denominators together. 1 x 1 ------ = ? 2 x 3 This is the same as the answer I

The associative property is about how numbers "associate", or group. 2.5(3x4) can also be grouped as (2.5x3)4. They both still equal 30, no matter how they look because addition and multiplication can be done in any order. The commutative property is about
Article I, Section 8, Clause 8 of the United States Constitution, known as the Copyright Clause, empowers the United States Congress "To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive
5 markers cost $4.75. You need to find the unit rate by dividing $4.75 by 5, which is 95 cents each. However, the question asks for the price of FOUR markers, so you have to multiple the price of an individual marker by four. .95 x 4 = $3.80 So your answer
Ooooh, that's a vague question. There are a number of factors that allowed the Europeans to succeed.As far as geography goes, the moderate temperature helped with agriculture and the abundance of water allowed fishing. Many of the world's greatest thinkers
He makes 400, and an extra 20 for each plan. If the variable Y is how much she makes, and X is the number of plans, then Y= 400 + 20X Then you just substitute how much she makes for Y, 680= 400 + 20X And solve for X.
C: In a galvanic cell the redox reaction is spontaneous and is responsible for the production of electrical energy. In an electrolytic cell, the redox reaction is not spontaneous and electrical energy has to be supplied to initiate the reaction.
To prevent is to keep something from occurring, so the only plausible answer would be C.
In decimal values, thousandths are less that hundredths. 20 thousandths are 2 hundredths, not the other way around.
Considering the subject is daycare, the only logical answer is C.
Probability= action×action P= 8/20 × 7/19 (because one blue is gone) P= 56/380 P= 14/95
Let T be total cost, and N be number of slices: T=$1.50N Substitute different values in for N, and arrange the input and output in a table. N.| 1 | 2 | 3 | 4 ---------------------------------- T.| 1.50 | 3 | 4.50 | 6
Maybe you could ask you teacher before that class starts, saying that the question wasn't clear. Or, if your school is anything like mine, you could go to tutorials in the morning and ask. For now, take a guess so you at least have an answer, and send some
