find the sum of the first 25 multiples of 10.
Answer:
Step-by-step explanation: So the first 25 multiples of 10 are ,
10,10,10,10 ect, to 25 the sum of all of the numbers is 250 i hope this helped!!!
Answer:
3250
Step-by-step explanation:
First 25 multiples of 10:
10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 = 55
11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 + 19 + 20 = 155
21 + 22 + 23 + 24 + 25 = 115
55 + 155 = 210
210 + 115 = 325
325 x 10 = 3250
Hope this helped!

Step-by-step explanation:
Yuto left his house at 10 a.M. To go for a bike ride. By the time Yuto's sister Riko left their house, Yuto was already 5.25 miles along the path they both took. If Yuto's average speed was 0.25 per minute and Riko's average speed was 0.35 per minute, over what time period in minutes,t, starting from when Riko left the house, will Riko be Behind her brother?
Answer:
The time period will be ;
10 am to 10 : 52 am
(Then she will catch up at exactly 10:52 am , 30 seconds)
Step-by-step explanation:
In this question, what we simply want to calculate is the amount of time it will take Riko to cover same distance as Yuto.
Mathematically, at any point in time;
Speed = distance/time
Let the time we are looking for be x minutes
At x minutes , Riko will be at a distance of 0.35 * x = 0.35x miles
At x minutes, Yuto will be at a distance of 5.25 miles + 0.25 * x = (5.25 + 0.25x) mikes
Kindly note that, at the time x minutes, the distance covered would have been equal;
Thus;
0.35x = 5.25 + 0.25x
0.35x -0.25x = 5.25
0.1x = 5.25
x = 5.25/0.1
x = 52.5 minutes
Over a time period of 52.5 minutes, Riko will be behind her brother ;
Since Yuto left at 10 am, the time period will be ;
10am to 10:52 am
Answer:
Sample Response: The solution means that Riko will be behind Yuto from the time she leaves the house, which corresponds to t = 0, until the time she catches up to Yuko after 52.5 minutes, which corresponds to t = 52.5. The reason that t cannot be less than zero is because it represents time, and time cannot be negative.

7k-10=-8-4(k+6)
Helpp
Answer:
k=-2
Step-by-step explanation:
7k-10=-8-4(k+6)
7k-10=-8-4k-24
7k-10=-32-4k
7k-10=-32-4k
11k-10=-32
11k=-22
k=-2
Step-by-step explanation:
7k-10= -8-4(k+6)
7k-10= -8-4k_24
7k+4k= -8-24+10
11k= -22
k= -22/11
k= -2

What is the equation in point slope form of the line that passes through the point (-1, -3) and has a slope of 4?
Oy-1=4(3-3)
Oy+3 = 4(x+1)
Oy+1=4(x+3)
Oy-3 = 4(2 - 1)
Answer:
The answer is y+3 = 4(x+1)Step-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
So we have
[tex]y + 3 = 4(x + 1)[/tex]

Allen's score in a video game was changed by −55 points because he missed some targets. He got −11 points for each missed target. How many targets did he miss?
Answer:
Allen missed 5 targets.
Step-by-step explanation:
You divide -55 by -11 to find how many targets he missed. But when you divide, you have to remember that a negative divided by a negative is a positive, so the answer will be postitive.
-55/-11=5
Are these two triangles similar???????!!!!!!! PLEASE HELP! I WILL GIVE BRAINILST AND MANY POINTS!
Answer:
yes the blue one is bigger but the green one is just smaller but if you multiply the sides by two it would be the same size so yeah they are similar
Step-by-step explanation:
Answer:
It's called Dilation when a triangle is the similar but only smaller, but as he said above, multiply the numbers by 2, you can't if they aren't numbers but if you do then it'll be the same size.

Slope = - 3/5, y-intercept = 5
Answer:
y = - [tex]\frac{3}{5}[/tex] x + 5
Step-by-step explanation:
Assuming you require an equation of the line.
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - [tex]\frac{3}{5}[/tex] and c = 5, thus
y = - [tex]\frac{3}{5}[/tex] x + 5 ← equation of line
After 200 feet of drilling on the first well, a soil test is taken. The probabilities of finding the particular type of soil identified by the test are as follows. P(soil | high-quality oil) = 0.20 P(soil | medium-quality oil) = 0.80 P(soil | no oil) = 0.20 How should the firm interpret the soil test? The probability of finding oil is good. Given the probability of finding good soil, the oil company is more likely to find oil. What are the revised probabilities?
Answer:
The revised probabilities are;
The probability of finding soil with oil = 0.8
The probability of finding soil with good oil = 0.16
The probability of finding medium quality oil = 0.64
Step-by-step explanation:
The given probability of finding soil with high quality oil, P(QO) = 0.20
The probability of finding soil with medium-quality oil, P(OM) = 0.80
The probability of finding soil with no oil, P(ON) = 0.2
Therefore, given that the probability of finding soil with no oil = 0.2, we have;
The probability of finding soil with oil, P(OP) = 1 - the probability of finding soil with no oil
P(OP) = 1 - 0.2 = 0.8
Which gives;
The probability, P(FG) of finding soil with oil and that the oil is good is given as follows;
P(FG) = P(QO) × P(OP) = 0.2 × 0.8 = 0.16
The probability of finding good oil = 0.16
Similarly;
The probability of finding medium quality oil P(FM) = P(OM) × P(OP) = 0.8 × 0.8 = 0.64
Which gives the revised probability as follows;
The probability of finding soil with oil, P(OP) = 0.8
The probability of finding soil with good oil, P(FG) = 0.16
The probability of finding medium quality oil, P(FM) = 0.64.
Problem number 26 of the Rhind Papyrus says: Find a quantity such that when it is added to StartFraction 1 Over 4 EndFraction of itself the result is a 15. The modern day equation that models this problem is x plus StartFraction 1 over 4 EndFraction x equals 15.. What is the solution to the equation? x = 10 x = 12 x = 15 x = 30
Answer:
[tex] x = 12 [/tex]
Step-by-step explanation:
x = the quantity to find
This quantity added to ¼ of itself gives 15.
Thus, this problem can be represented as given above:
[tex] x + \frac{1}{4}x = 15 [/tex]
Solve for x
[tex] x + \frac{x}{4} = 15 [/tex]
[tex] \frac{4x + x}{4} = 15 [/tex]
[tex] \frac{5x}{4} = 15 [/tex]
Multiply both sides by 4
[tex] \frac{5x}{4}*4 = 15*4 [/tex]
[tex] 5x = 60 [/tex]
Divide both sides by 5
[tex] \frac{5x}{5} = \frac{60}{5} [/tex]
[tex] x = 12 [/tex]

An auto mechanic earns $498.75 in 35 hours during the week. His pay is $2.50 more per hour on weekends. If he works 6 hours on the weekend in addition to the 35 hours during the week, how much does he earn? A. What questions do you need to answer to solve the problem.
Answer:
$513.75
Step-by-step explanation:
Let h represent the number of hours he worked in a week
An auto mechanic earns $498.75 in 35 hours during the week. His pay is $2.50 more per hour on weekends.
Hence, his pay Is represented by equation:
$498.75 + $2.50 × x
If he works 6 hours on the weekend in addition to the 35 hours during the week
$498.75 + $2.50 × 6
= $498.75 + $15
= $513.75
Therefore, he earns $513.75
