Debra and Alexandria can finish a plowing job in two hours if they work together. Debra can do the job in 7 hours by herself. How long would it take Alexandria to finish the same job alone?
Answers
Answer:
2 hours 48 minutes
Step-by-step explanation:
Debra=1 plowing job / 7 hours
Debra+Alexandra=1 plowing job / 2 hours
1/2-1/7
=7/14-2/14
=5/14
=1/14/5 (Alexandra can do 1 unit of plowing job per 14/5 hours)
14/5 hour=2 hours 48 minutes (hope hits helps)
Alexandria to finish the same job alone in, 2 hours 48 minutes
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
Debra and Alexandria can finish a plowing job in two hours if they work together.
And, Debra can do the job in 7 hours by herself.
Hence, We get;
For Debra = 1 plowing job / 7 hours
Debra + Alexandra = 1 plowing job / 2 hours
Hence, Time to take Alexandria to finish the same job alone is,
= 1/2 - 1/7
= 7/14 - 2/14
= 5/14
= 1/14/5 (Alexandra can do 1 unit of plowing job per 14/5 hours)
= 2 hours 48 minutes
Thus, Alexandria to finish the same job alone in, 2 hours 48 minutes

Answers
Answer:

Step-by-step explanation:
Assuming x is the length DB
Δ DSR and Δ DBC are similar, so ratios of corresponding sides are equal, that is
[tex]\frac{DB}{DS}[/tex] = [tex]\frac{DC}{DR}[/tex] , substitute values
[tex]\frac{DB}{10}[/tex] = [tex]\frac{12}{8}[/tex] ( cross- multiply )
8 DB = 120 ( divide both sides by 8 )
DB = 15
That is x = DB = 15

Two sides of a triangle have lengths 7 and 15. Which inequality represents the possible lengths for the third side , x?
Answers
Answer:
8 < x <22
Step-by-step explanation:
In this question we know the two sides of the triangle to be 7 and 15, let's all the other side x
One one side of the inequality we have:
7+15>x
22 > x
On the other side we have
7 + x > 15
X > 15-7
X>8
When we rearrange these inequalities above we have
8<X<22
We saw from the calculations that 8 is less than X and X is less than 22.

Step-by-step explanation:
Sample space for the sum of 2 spins :
Number on spinner = 2, 5, 4
____ 2 ___ 5 _____4
2___ 4 ___ 7 _____ 6
|
5___ 7 ___ 10 ____ 9

4___ 6 ___ 9 ____ 8
Hence,
(4, 7, 6, 7, 10, 9, 6, 9, 8)
Probability of getting a sum less than or equal to 8;
Probability = required outcome / Total possible outcomes
Required outcome =, sum ≤ 8 = 6
Total possible outcomes = 9
P(sum ≤ 8) = 6/9 = 2/3
Determine whether the conclusion is valid. Explain.
You want to determine the number of students in your school who have visited a science museum. You survey 50 students at random. Twenty have visited a science museum, and thirty have not. So, you conclude that 40% of the students in your school have visited a science museum.
A. yes; The sample is representative of the population, selected at random, and large enough to provide accurate data. So, the sample is unbiased and the conclusion is valid.
B. yes; The sample is representative of a specific group, selected based on age, and small enough to provide accurate data. So, the sample is biased and the conclusion is valid.
C. no; The sample is not representative of the population because students who are older have had more opportunities to visit a science museum. So, the sample is biased and the conclusion is not valid.
D. no; The sample is representative of the population, selected at random, and too large. So, the sample is unbiased and the conclusion is not valid

I have attached the complete question with the triangle.
Answer:
x = 6
Step-by-step explanation:
From the image attached we are told to find x in the triangle.
The triangle is a right angle triangle and so we can use pythagoras theorem to find x.
x² = 6.5² - 2.5²
x² = 42.25 - 6.25
x = √36
x = 6

Sally's age is 2 plus 3 times John's age. Together, Sally and John's age equals 30. How old is Sally?
Answers
Answer:
Sally is 23 years old.
Step-by-step explanation:
John's age is completely unknown, so it is known as x
Meanwhile, Sally's age can be represented as 3x+2
The sum of both ages is 30.
So, x+3x+2=30
Combine like terms.
4x+2=30
Subtract 2 from both sides.
4x=28
Divide both sides by 4.
x=7
John is 7 years old.
Sally's age: 3(7)+2=23
Sally is 23 years old.
