Answer:
Im sorry if this is wrong.
a quarter is 1/4. 1/4 is .25 so 360-25=335. so she only did 335 degree spin and was 25 degrees short
Step-by-step explanation:
The degree of spin Sarah wants to = 360 degrees
Hence, 1 turn = 360 degrees
Sarah does a quarter turn
A quarter is equivalent to : [tex]\frac{1}{4}[/tex]
So, [tex]\frac{1}{4}[/tex] turn = [tex]\frac{1}{4}[/tex] x 360 degrees
= 90 degrees.
The number of degrees short of her goal that Sarah was of her first attempt is calculated as :
360 degrees - 90 degrees
= 270 degrees.
Therefore, Sarah was 270 degrees short of her goal at her first attempt.

A scientist studied bacteria.
She placed 4 bacteria in a dish.
The population of bacteria triples every 12 hours
Which equation can be used to determine the number of bacteria, y, present after x days?
O y = 4(3)x
O y=4(6)x
O y = 4(3) 2x
O y = 4(6) 2x
Answer:
the answer to the question is A
An equation is formed of two equal expressions. The equation can be used to determine the number of bacteria, y, present after x days is y = 4(3)²ˣ.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Scientists placed 4 bacteria in a dish. The population of bacteria triples every 12 hours. Therefore, the equation that can be used to determine the number of bacteria, y, present after x days are:

bob claims that he can map rectangle 1 to rectangle 2 select all of the transformations or series of transformation that support his claim
Answer:
The first thing you need to notice is that each mark in the coordinate axis represents 2 units.
Now, let's analyze each option that maps rectangle 1 to rectangle 2.
Reflection over the line x = 1, and a translation of 2 units down.
You can see that the right end of rectangle 1 us located at x = -2
The distance between x = -2 and the line of reflection is:
1 - (-2) = 3
Then the left end of the reflected rectangle will e 3 units at the right of x = 1.
1 + 3 = 4
Will be at x = 4, same as rectangle 2.
Now we move it 2 units down, and we will have rectangle 1 mapped into rectangle 2.
Translation of 12 units right, and then 2 units down.
The right end of rectangle 1 is at x = -2
The right side of rectangle 2 is at x = 10
The difference is 10 -(-2) = 12
Then we must move rectangle 1 12 units to the right.
Now, same as before, we can move rectangle 1 2 units down and we will have rectangle 1 mapped into rectangle 2.
Rotation of 180° around the point (1, 4)
This means a reflection over the line x = 1, followed of a reflection over the line y = 4.
We already see that a reflection over the line x = 1 leaves rectangle 1 right above rectangle 2. And the line that separates them is the line y = 4, then when we do a reflection over that line, we will have rectangle 1 mapped into rectangle 2.

Step-by-step explanation:
Oscar is raising monarch caterpillars for a summer science project. Every day, he feeds 4 fresh milkweed leaves to each caterpillar. Oscar wants to know how many caterpillars he can feed in a day with a total of 28 leaves. Which equation can Oscar use to find n, the number of caterpillars he can feed in a day?
Answer: n = 28/4
Step-by-step explanation:
Number of leaves uses to feed each caterpillar = 4.
If Oscar has 28 leaves, the number of caterpillars n he'll be able to feed in a day will be represented by the equation below:
n = 28/4
This implies that 7 caterpillars can be fed in a day.

If you order 3 chickens wraps and order 2 orders of potatoes for a total bill of $42.95 someone else orders 5 chicken wraps and 4 orders of potatoes for a total bill of $74.91. What is the cost of a chicken wrap and what is the cost of one order of potatoes
Answer: The cost of a chicken wrap is $10.99
The cost of one order of potatoes is $4.99.
Step-by-step explanation:
Let the cost of a chicken wrap be x
Let the cost of one order of potatoes be y.
From the question,
3x + 2y = $42.95 ...... equation i
5x + 4y = $74.91 ....... equation ii
Multiply equation i by 5
Multiply equation ii by 3
15x + 10y = $214.75 ..... equation iii
15x + 12y = $224.73 ....... equation iv
Subtract equation iv from equation iii. This will be:
-2y = -$9.98
y = $9.98/2
y = $4.99
Since 3x + 2y = $42.95
3x + 2($4.99) = $42.95
3x + $9.98 = $42.95
3x = $42.95 - $9.98
3x = $32.97
x = $32.97/3
x = $10.99
The cost of a chicken wrap is $10.99
The cost of one order of potatoes is $4.99.

Answer:
x = 1/2
Step-by-step explanation:
Step 1: Write equation
-4x + 6(4x - 3) = -8
Step 2: Solve for x
Distribute 6: -4x + 24x - 18 = -8Combine like terms: 20x - 18 = -8Add 18 to both sides: 20x = 10Divide both sides by 20: x = 1/2Step 3: Check
Plug in x to verify it's a solution.
Substitute: -4(1/2) + 6[4(1/2) - 3] = -8Evaluate: -2 + 6[2 - 3] = -8Evaluate: -2 + 6(-1) = -8Evaluate: -2 - 6 = -8Evaluate: -8 = -8can anyone explain how to find slope?

so you will have to use m= rise/ run and for ex if you have the points (4,6) and (-3,3) you would lable 4 as x1, 6 as y1, -3 as x2, and finally 3 as y2 then you would use this form to find slope m= y2-y1/ x2-x1 then you would plug in numbers 3 - 6/ -3 - 4 then you would do the math and get -3/-7 (2 negatives equal a positive) so you would get 3/7 and theres the slope the slope is 3/7

Answer: 498,173.26.
Step-by-step explanation:
Place value of the 9 in 329,513 = 9,000
9 is 10 times the value of the 9 in 329,513.
Then, place value of 9 in required number = 10x 9,000 = 90,000
from options only 95,826 and 498,173.26 has 9 at ten thousands place. (cancel all other options)
Also, 2 is [tex]\dfrac1{10}[/tex] the value of the 2 in 7,562.
place value of 2 in required number =[tex]\dfrac1{10}\times2=0.2[/tex]
i.e. place value of 2 in required number 2 tenths
which is in 498,173.26 [place value of 6 is [tex]\dfrac1{10}[/tex] the value of the 6 in 4.68]
Hence, th required number is 498,173.26.

a) 12 = 2 × 2 × 3
2.Find the prime factorization of 196
a) 196 = 2 × 2 × 7 × 7
To find the GCF, multiply all the prime factors common to both numbers:
a)GCF=2x2
Therefore, GCF = 2 × 2
GCF = 4
The greatest common factor of the numbers 196 and 12 is 4.
What is the greatest common factor?The largest factor of the two numbers which divides both numbers is called as greatest common factor or GCF. The greatest common factor is the largest number which can divide both the numbers.
1. Find the prime factorization of 12
12 = 2 × 2 × 3
2. Find the prime factorization of 196
196 = 2 × 2 × 7 × 7
To find the GCF, multiply all the prime factors common to both numbers:

Cory, Josh and Dan went shopping for Halloween treats. Cory bought 3 chocolate pumpkins, 4 masks and 8 candy witches. He spent $36.65. Josh bought 5 chocolate pumpkins,3 masks and 10 candy witches. He spent $37.50. Dan bought 4 chocolate pumpkins, 5 masks and 6 candy witches. He spent $43.45. Write a system of equations to represent this problem.
Answer:
[tex]\left\{\begin{matrix}3x+4y+8z=36.65\\ 5x+3y+10z=37.50\\ 4x+5y+6z=43.35\end{matrix}\right.[/tex]
Step-by-step explanation:
System of equations
Let's set the following variables:
x=Price of chocolate pumpkins
y=Price of masks
z=Price of candy witches
We'll establish the system of equations needed to know the prices of all the Halloween treats.
Cory bought 3 chocolate pumpkins, 4 masks, and 8 candy witches and he spent $36.65. This leads to the following equation:
[tex]3x+4y+8z=36.65\qquad\qquad [1][/tex]
Josh bought 5 chocolate pumpkins, 3 masks, and 10 candy witches and he spent $37.50. This leads to the following equation:
[tex]5x+3y+10z=37.50\qquad\qquad [2][/tex]
Dan bought 4 chocolate pumpkins, 5 masks, and 6 candy witches and he spent $43.45. This leads to the following equation:
[tex]4x+5y+6z=43.35\qquad\qquad [3][/tex]
Collecting the equations [1] [2] [3], we form the system of equations to represent this problem:
[tex]\left\{\begin{matrix}3x+4y+8z=36.65\\ 5x+3y+10z=37.50\\ 4x+5y+6z=43.35\end{matrix}\right.[/tex]
