Answer:
38
Step-by-step explanation:
If you add 3 to the numbers, then you add 3 to the average, or mean.
Answer:
38
Step-by-step explanation:
24 * 35 = 840
24 * 3 = 72
840 + 72 = 912
912 / 24 = 38
The length of a rectangle exceeds its width by 5 inches. The
area of the rectangle is 84 square inches. Find its dimensions.
Answer:
The area is the product of length and width, which is to say that the length and width are factors of the area.
Assuming the dimensions are integers, you want factors of 84 that differ by 5.
Step-by-step explanation:
... 84 = 1×84 = 2×42 = 3×28 = 4×21 = 6×14 = 7×12
The last of these pairs differ by 5, so ...
the length is 12 inches
the width is 7 inches.
The answer is l=12, w=7
Answer:
Step-by-step explanation:
Givens
Let the width be w
Let the length be w + 5
Let the area = 84
Equation
A = L*w
Solution
x(x + 5) = 84 Remove the brackets
x^2 + 5x = 84 Subtract 84 from both sides
x^2 + 5x - 84 = 0 This will factor
(x - 7)(x + 12) =0
x + 12 has no meaning. Geometry does not use negative numbers.
x - 7 = 0 Add 7 to both sides
x = 7
The width = 7
The length = 7 + 5 = 12
1/8x -5 < -8
I know that I add 5 to both sides, but that gives me:
1/8x < -3
which results in something along the lines of ".375" and I'm NOT allowed to answer in decimals
Answer:
[tex]x<-24[/tex]
Step-by-step explanation:
You are correct, you do add 5 to both sides and get
[tex]\frac{x}{8} <-3[/tex]
Then you multiply by 8 on both sides to get
[tex]x<-24[/tex]

IDK WHY ITS SPREAD APART
Answer:
I answered #1 on a previous question
2) A
Step-by-step explanation:
2) So the formula for consecutive integers is x+x+1+x+2 and so on.
So we know there are 6 integers so the final would be x+5.
so the sum of the final and the first is x+5+x=1
Simplify the equation and solve
2x+5=1
2x=-4
Divide 2 on both sides
x=-2
so -2 is the least Interger of all.
Check: Use the equation x+5 since it’s the greatest, so since x is -2 subsitute and you’ll get -2+5 you'll get 3 and 3+-2=1
Find the 14th term of the geometric sequence 5 -10 20
Answer:
a14 = -40,960
Step-by-step explanation:
The sequence has a first term of 5 and a common ratio of -10/5 = -2, so the n-th term is given by ...
an = a1·r^(n-1)
an = 5·(-2)^(n-1)
The 14th term is then ...
a14 = 5·(-2)^(14-1) = -5·2^13 = -5·8192
a14 = -40,960

Write the equation of the line that passes through (2, 6) and (-2, 4).
Answer:
y-6=1/2(x-2) or y=1/2x+5
Step-by-step explanation:
First, let's find the slope of the line.
Slope is y2-y1/x2-x1 or rise/run
Let's label (2,6) and (-2,4)
x1=2
y1=6
x2=-2
y2=4
now plug in the numbers
4-6/-2-2 = -2/-4=1/2
now, let's make it a line
Point slope form is y-y1=m(x-x1) (m is slope)
Plug the points in
y-6=1/2(x-2)
of course, you could always simplify it to y=1/2x+5 (y=mx+b) format if you want.
Hope this helps!
How do you factor 9x²-16y²?
Answer :
9x² - 16 y²
★ Firstly, we'll break down 9 and 16 -
Here,
9 is square of 316 is square of 4→ (3x)² - (4y)²
→ (3x - 4y) (3x + 4y)
Therefore, the factor of 9x² - 16y² is (3x - 4y) (3x + 4y).
*A bag contains 3 red and 4 blue balls of the same size. Two balls are drawn one after
another without replacement. Show all the probabilities in a tree diagram.
Please help!
Answer: see below
Step-by-step explanation:
3 Red balls and 4 Blue balls makes a total of 9 balls
1st Draw 2nd Draw Outcome Probability
Red: P(R) = 3/7 Red: P(R₂/R₁) =1/3 Red, Red (3/7) x (1/3) = 1/7
Red: P(R) = 3/7 Blue: P(B₂/R₁) =2/3 Red, Blue (3/7) x (2/3) = 2/7
Blue: P(B) = 4/7 Red: P(R₂/B₁) =1/2 Blue, Red (4/7) x (1/2) = 2/7
Blue: P(B) = 3/7 Blue: P(B₂/B₁) =1/3 Blue, Blue (4/7) x (1/2) = 2/7
Check: Total = 7/7 = 1
Notes:
P(R₂/R₁) means the probability that the 2nd ball is red given that the 1st ball was red. Since you started with 3 red balls out of 7 total balls but previously pulled one red ball out, you now have 2 remaining red balls out of 6 remaining total balls.
2 red / 6 total = 1/3
P(B₂/R₁) means the probability that the 2nd ball is blue given that the 1st ball was red. Since you started with 4 blue balls out of 7 total balls but previously pulled one red ball out, you still have 4 blue balls but only 6 total remaining balls.
4 blue / 6 total = 2/3
P(R₂/B₁) means the probability that the 2nd ball is red given that the 1st ball was blue. Since you started with 3 red balls out of 7 total balls but previously pulled one blue ball out, you still have 3 red balls but only 6 total remaining balls.
3 blue / 6 total = 1/2
P(B₂/B₁) means the probability that the 2nd ball is blue given that the 1st ball was blue. Since you started with 4 red balls out of 7 total balls but previously pulled one blue ball out, now have 3 remaining red balls out of 6 total remaining balls.
3 blue / 6 total = 1/2

The length of a particular bacteria cell is 1.5×10−7 meters, and the length of a human red blood cell is 9×10−6 meters. How many times larger is the red blood cell as compared to the bacteria cell?
Answer:
60
Step-by-step explanation:
The ratio of sizes is ...
blood cell / bacteria = 9×10^-6/(1.5×10^-7) = 90×10^-7/(1.5×10^-7)
= 90/1.5 = 60
The red blood cell's length is 60 times that of the bacteria.
