The sum of 5 consecutive odd integers is 145. These are the other 4 consecutive odd numbers. Now if we add all of these up we will get this : 25 + 27 + 29 + 31 + 33 = 145.
Hope I helped! ☺☼
The five consecutive odd numbers that sum up to 145 are 25, 27, 29, 31, and 33.
Let's call the middle of the five consecutive odd numbers n. Because these numbers are odd and consecutive, the two numbers before n will be n-2 and n-4, and the two after will be n+2 and n+4. The sum of these five numbers is:
n-4 + n-2 + n + n+2 + n+4 = 5n.
Since the sum of the five numbers is 145, we have:
5n = 145.
To find the value of n, we divide both sides by 5:
n = 145 / 5,
n = 29.
So the middle number is 29, and the five consecutive odd numbers are 25, 27, 29, 31, and 33.
The above question is incomplete, the complete question is:
The sum of 5 consecutive odd numbers is 145. find the numbers.

Jeff has 4 red pens and 2 blue pens in his backpack. He also has 1 yellow highlighter and 4 green highlighters in his
backpack. If he reaches into his backpack and grabs one pen and one highlighter without looking, what is the probability
that he will grab a blue pen and a yellow highlighter?
Answer:
[tex]\frac{1}{15}[/tex]
Step-by-step explanation:
In probability,
"AND" means "multiplication"
"OR" means "ADDITION"
We want probability of Blue Pen and Yellow Highlighter. So we find individual probabilities and "MULTIPLY" them.
Let P(b) be probability of blue pen
Let P(y) be probability of yellow highlighter
We know probability of event is that event divided by total number of that
So,
There are 4 + 2 = 6 pens
Blue pen = 2
Hence,
P(b) = 2/6 = 1/3
And,
There are 5 highlighters
Yellow highlighter = 1
Hence,
P(y) = 1/5
Now,
P(b and y) = 1/3 * 1/5 = 1/15
Hence,
probability of grabbing blue pen and a yellow highlighter is [tex]\frac{1}{15}[/tex]

x=(404/65)/4=101/65
x=101/65, y=-16/65.
Mrs. Wadley is tie-dying t-shirts for her AP Stats class. White shirts cost $4 each and black shirts are $5 each. There are 18 students in the class, and she spent $75. How many white shirts did she buy ? how many black shirts?
Mrs. Wadley bought 15 white shirts and 3 black shirts.
Step-by-step explanation:
Cost of one white shirt = $4
Cost of one black shirt = $5
Students in class = 18
Money spent on shirts = $75
Let,
white shirts = x
black shirts = y
According to given statement;
x+y=18 Eqn 1
4x+5y=75 Eqn 2
Multiplying Eqn 1 by 5;
[tex]5(x+y=18)\\5x+5y=90\ \ \ \ Eqn\ 3[/tex]
Subtracting Eqn 2 from Eqn 3;
[tex](5x+5y)-(4x+5y)=90-75\\5x+5y-4x-5y=15\\x=15[/tex]
Putting x=4 in Eqn 1
[tex]15+y=18\\y=18-15\\y=3[/tex]
Mrs. Wadley bought 15 white shirts and 3 black shirts.

Given that 4:5:8 is equivalent to 1:n:b. Find the ratio of n:b only.
Step-by-step explanation:
So 4:5:8
= 1:n:b
which means that 4/n= 1
n= 1x4 so n=4
Now we know that 4 is divided by 4 to get 1, so we do the same for the other two values.
5/4= 1.25 and 8/4= 2
So now place the values for n:b
n= 1.25 b=2
So n:b= 1.25:2
To check, multiply each of the values in 1:1.25:2 by 4 and see if the answer you get is the same as 4:5:8.
A metalworker has a metal alloy that is 30% copper and another alloy that is 55% copper. How many kilograms of each alloy should the metalworker combine to create 100 kg of a 50% copper alloy? The metal worker should use (blank) kilograms of the metal alloy that is 30% copper and (blank) kilograms of the metal alloy that is 55% copper. (show your work)
X+Y=100kg
X=100-Y
X*0.3+Y*0.55=100*0.5
(100-Y)*0.3+Y*0.55=50
30-0.3*Y+0.55*Y=50
0.25*Y=20
Y=80 kg
X=100-80
X=20 kg
The metal worker should use 20 kilograms of the metal alloy that is 30% copper and 80 kilograms of the metal alloy that is 55% copper.
Answer:

What is the midpoint of a line segment with endpoints at (3,-1) and (8, -4)?
The midpoint of a line segment with endpoints at (3,-1) and (8, -4) is [tex]\left(\frac{11}{2},-\frac{5}{2}\right)[/tex]
Solution:
We have been given 2 end points of a line which are: (3,-1) and (8, -4)
The midpoint of a line segment is half way from both the ends of the line segment.
The formula for midpoint for the two points [tex]P(x_1, y_1) \text{and} Q(x_2, y_2)[/tex] is given as:
[tex]\text {Midpoint}=(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2})[/tex]
Here P(3, -1) and Q(8, -4)
[tex]\text { So } x_{1}=3 ; x_{2}=8 ; y_{1}=-1 ; y_{2}=-4[/tex]
Plugging in values in above formula, we get
[tex]\begin{array}{l}{\text {Midpoint}=(\frac{3+8}{2}, \frac{-1-4}{2}})\\\\ {\text {Midpoint}=(\frac{11}{2}, \frac{-5}{2}})\end{array}[/tex]
Hence, the midpoint of the line segment is [tex]\left(\frac{11}{2},-\frac{5}{2}\right)[/tex]
A water park charges a rental fee plus $1.50 per hour to rent inflatable rafts. The total cost to rent a raft for 6 hours is $15. Assume the relationship is linear. Find and interpret the rate of change and the initial value.
Answer:
C = 6 + 1.5h.
$6 is the fixed fee that the park charges.
And $1.5 is the rate of charge per hour for rent of the raft.
Step-by-step explanation:
The water park charges a rental fee plus $1.5 per hour to rent inflatable rafts.
Let the total charge (C) has a linear relationship with the number of hours (h) spent in the park and it is C = a + bh ......... (1)
Now, b is the rate of charge to rent inflatable rafts and b = $1.5 per hour.
So, C = a + 1.5h ........... (2)
Now, given that the total cost to rent a raft for 6 hours is $15.
So, from equation (2) we get,
15 = a + 1.5 × 6
⇒ a = 6
Therefore, the equation (2) becomes C = 6 + 1.5h.
Here, $6 is the fixed fee that the park charges.
And $1.5 is the rate of charge per hour for rent of the raft. (Answer)
Greta is 1 1/2 meters tall which of the following is equivalent to 1 1/2 meters
1 1/2 meters is equivalent to 1500 millimeters.
The correct option is (b).
To find out which option is equivalent to 1 1/2 meters, we need to convert 1 1/2 meters to millimeters.
Given:
- Gretta's height is 11/2 meters.
To convert meters to millimeters, we'll use the fact that 1 meter is equal to 1000 millimeters.
So, to convert 1 1/2 meters to millimeters:
[tex]\[ \text{1 1/2 meters} = (1 + 1/2) \times 1000 \text{ millimeters} \][/tex]
[tex]\[ = (1.5) \times 1000 \text{ millimeters} \][/tex]
[tex]\[ = 1500 \text{ millimeters} \][/tex]
So, 1 1/2 meters is equivalent to 1500 millimeters.
Therefore, the correct option is:
b. 1500 millimeters

The vertices of triangle ABC are A(−5, 1), B(−2.5, 7), and C(0, 1). Find the new coordinates of the vertices after the given translation.
Answer:
A'(-2,0) , B'(0.5,6) and C'(3,0)Step-by-step explanation:
The vertices of triangle ABC are A(−5, 1), B(−2.5, 7), and C(0, 1).
The given translation of vertices,
(x, y) → (x + 3, y − 1)This translation shows shift x-coordinate 3 unit right and y-coordinate 1 unit down.
First translate vertices A(-5,1)[tex]A(-5,1)\rightarrow A'(-5+3,1-1)[/tex]
New vertices A'(-2,0)
Now vertices B(-2.5,7)[tex]B(-2.5,7)\rightarrow B'(-2.5+3,7-1)[/tex]
New vertices B'(0.5,6)
Now vertices C(0,1)[tex]C(0,1)\rightarrow C'(0+3,1-1)[/tex]
New vertices C'(3,0)
Hence, the new coordinate of the vertices are A'(-2,0) , B'(0.5,6) and C'(3,0)
Point Q(-1, 5) is reflected across the line x = -1. What are the coordinates of its image? (5, -1) (1, 5) (-1, -5) (-1, 5)
Answer:
(-1,5)
Step-by-step explanation:
The line x = -1 is a vertical line parallel to the y-axis.
Therefore, if the point Q(-1,5) reflects on line x = -1, then the y-coordinate of the image point will not change.
Again, as the point Q(-1,5) is on the line x = -1, therefore, the image will be the point itself i.e. (-1,5). (Answer)
The horizontal distance from point (-1,5) to the line x = -1 is zero.

The sum of three numbers is -44.84. One of the numbers is 24.6. The other numbers are equal to each other. What is the value of each of the other two numbers?
Answer:
-34.72
Step-by-step explanation:
a + b + c = -44.84
a= 24.6
24.6 + b + c = -44.84
Since b = c (given "the other numbers are equal to each other")
Substitute b into c, we have
24.6 + b + b = -44.84 (b+b is the equivalence of 2 x b)
24.6 + 2b = -44.84 (subtract 24.6 from both sides)
2b = -69.44 (divide 2 from both sides)
b= -34.72
Since b = c (given "the other numbers are equal to each other")
c is also -34.72
