find the sum of all positive integers less than 200 which are divisible by 3
Answer:
we will use the sum of natural number series formula
if S=1+2+3+4+n, then
S= n(n+1) ;
2
Now, sum of all +ve integers from 0 to 200 is given by
S=0+1+2+3+200
=> S=200(200+1)/2;
=>S=20100;
Sum of all +ve integers divisible by 5 is given by
R=0+5+10+15+20+25+30+200
R=5(1+2+3+4+5+6+40)
R=5*40(40+1)/2
R=4100 ;
therefore the sum of all +ve integers <200 and not divisible by 5=S-R=16000

Next three terms = 1/2, 1/4 and 1/8.
Step-by-step explanation:
This is a geometric progression and the common ratio will be calculated as the second term divided by the first term. This will be:
= 4/8.
= 1/2
The next three terms will then be:
1 × 1/2 = 1/2
1/2 × 1/2 = 1/4
1/4 × 1/2 = 1/8
Therefore, the next three terms are 1/2, 1/4 and 1/8.

Share $240 between Alex and Burton in the radio:
5:1
Answer:
$200 : $40
(i divided 240 by 6 because there are six parts in the ratio, and got 40. 40*5=200 and the other 40 makes it 240 in the ratio of 5:1)
Step-by-step explanation:
Answer:
Alex : Burton
5 : 1
5+1=6
240/6=40
5 times 40=200
1 times 40 =40

Justine estimated that she would drive 24 miles to get to the beach. It is a good thing she had plenty of gas because she got lost and ended up driving 36 miles to get to the beach. What was the percent error
Answer:
50%
Step-by-step explanation:
Actual value - estimated value
Actual value = 24 miles
Estimated value = 36 miles
Estimated value - Actual value
= 36 miles - 24 miles
= 12 miles
% error = change in value / actual value × 100
= 12/ 24 × 100
= 1/2 × 100
= 50%
% error = 50%

2feet 8incher+1foot6incher=
Answer:
Answer is 50 Inches or 4 feet, 2 inches
Step-by-step explanation:
First I would make everything inches so that it's easier:
2 feet is 24 inches, 1 foot is 12 inches
Then, add everything:
24+8+12+6 = 50 inches
You can leave the answer like this, or convert to feet again: (since there are 12 inches in a foot, divide 50 by 12. It's easiest to keep it as a mixed number.)
50/12 = 4 2/12
Answer is 50 Inches or 4 feet, 2 inches

At the local video game store, a popular game went from $120 to $85 in a weeks time. What is the percent decrease of the item? Round to the nearest whole percent. Group of answer choices
Answer: 29%
Step-by-step explanation:
The game went from the price of $120 to $85.
In calculating percentage decrease, use the following formula:
= (New Price - Old price) / Old price
= (85 - 120) / 120
= -35 / 120
= -29%
Price therefore decreased by 25%

The solids are similar. Find the missing dimension.
Answer:
The missing dimension is 25 inches
Step-by-step explanation:
If the solids are similar, then the ratio of the corresponding sides are equal
We have the ratio of the height to the diameter in both
kindly recall, 1 ft = 12 inches
so 10ft = 120 in
4 ft = 48 in
We have this as;
48/120 = 10/d
48d = 1200
d = 1200/48
d = 25 inches

If each unit equals one mile, what is the distance (in a straight line) between the library and the school rounded to the nearest tenth?
Answer:
3.2 miles
Step-by-step explanation:
Given the coordinate point (6,2) and (3,3)
The distance between the two points is expressed using the formula;
D = √(x2-x1)²+(y2-y1)²
D = √(3-2)²+(3-6)²
D = √1²+(-3)²
D = √1+9
D = √10
D = 3.2
Hence the distance (in a straight line) between the library and the school rounded to the nearest tenth is 3.2 miles

What is 7x2? Please help! I need it!
Answer:
7 x 2 is 14.
Step-by-step explanation:
Its the same thing as 7 plus 7.
The Multiplication of 7 and 2 results to 14.
What is Multiplication?The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the factors that are multiplied are referred to as the factors. Repeated addition of the same number is made easier by multiplying the numbers.
We have to multiply 7 x 2.
So, we can either add 7 two times as
= 7 + 7
= 14
or we can multiply it
= 7 x 2
= 14

1. In a shot put event, an athlete throws the shot put with an initial velocity of 38 feet per
second and releases it from a height of 5 feet. How high above the ground is it after 2
seconds
Answer: after two seconds it would be ground level due to the fact that during the 1 second mark it was at 5 feet above ground, so then it would disperse energy going back to ground level, or atleast to 2.5 feet off the ground. This question wouldn’t make sense applied to logic in real life.

x=7
Step-by-step explanation:
You would set them equal to each other and solve for x.
We set them equal to each other becuase they are congruent.
Answer:
x=7
Step-by-step explanation:
we know that both degrees are equal to each
other so we set (17x-10)=(15x+4)
Let's solve your equation step-by-step.
17x−10=15x+4
Step 1: Subtract 15x from both sides.
17x−10−15x=15x+4−15x
2x−10=4
Step 2: Add 10 to both sides.
2x−10+10=4+10
2x=14
Step 3: Divide both sides by 2.
