Step-by-step explanation:
Brad put 10 crickets in his pets lizard cage. After one day, Brad's lizard had eaten 50% of the crickets he had put in the cage. By the end of the next day, the lizard had eaten 20% of the remaining crickets. How many crickets were left in the cage at the end of the second day?
Answer:
There are 4 crickets left
Step-by-step explanation:
10/2=5
20% of 5 is 1
5-1=4

Answer:
4 crickets
Step-by-step explanation:
On the first day, the lizard ate 50% of the 10 crickets it was given. 50% of 10 is 5 (10 times 0.5), so five crickets remain. The next day, the lizard ate 20% of the 5 remaining crickets. 20% of 5 is 1 (5 times 0.2), and 5-1=4, so 4 crickets are left.

All the parts are solved below.
What is a function? What is equation modelling? What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the functionEquation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given are the equations -
1. 2a=4.6
2. b+2=4.6
3. c÷2=4.6
4. d−2=4.6
5. e+38=2
6. 18f=3
7. g÷85=1
We have -
[1] -
2a = 4.6
a = 2.3
[2] -
b + 2 = 4.6
b = 2.6
[3] -
c ÷ 2 = 4.6
c x 1/2 = 4.6
c = 4.6 x 2
c = 9.2
[4] -
d − 2 = 4.6
d = 6.6
[5] -
e + 38 = 2
e = - 36
[6] -
18f = 3
f = 3/18
f = 1/6
[7] -
g ÷ 85 = 1
g x 1/85 = 1
g = 85
Therefore, all the parts are solved above.

Part A: Identify the Minimum, First Quartile, Median, Third Quartile, and Maximum for the data.
64, 53, 60
60, 56, 58
51, 55, 60
A. Minimum: 51, First Quartile: 55, Median: 58, Third Quartile: 60; Maximum: 64
B. Minimum: 51, First Quartile: 55.5, Median: 59, Third Quartile: 60; Maximum: 64
C. Minimum: 51, First Quartile 54.5, Median: 57, Third Quartile: 60; Maximum: 64
D. Minimum: 51, First Quartile: 54, Median: 58, Third Quartile: 60; Maximum: 64
Answer:
Yes! This is my area!
Step-by-step explanation:
Minimum= 51
Maximum=64
To find the median put the numbers in order
51,53,55,58,60,60,64
no cross off one by one to get the middle number
you end up with 58
first quartile is the upper half so that would be 53
third quartile is the lower half so that wou;d be 60
Hope this helps!
Answer:
D
Step-by-step explanation:
when you put them in numerical order, you have 51, 53, 55, 56, 58, 60, 60, 60, 64
the minimum is the smallest number in the data set. the maximum is the largest number in the data set.
the median is the measure of center, which indicates the middle number in the data set
the first quartile is the center of the bottom set of the data
the third quartile is the center of the upper set of the data
(the upper and lower sets are indicated by which side of the median they are on)
hope this helped :)
Solve this equation:
3 (5x + 2) - 7 (3x - 4) = (5 - 9x) 2
I need step by step explanation with details.
Thank you!
Answer:
x = - 2
Step-by-step explanation:
3(5x + 2) - 7(3x - 4) = (5 - 9x)2
15x + 6 - 21x + 28 = 10 - 18x
34 - 6x = 10x - 18
-12x = 24

Use a system of equations to find two numbers with a difference of 2 and a sum of -8. Show your work.
Answer:
-3 & -5
Step-by-step explanation:
let the two numbers be x and y
x + y = -8. sum of the numbers is -8
x - y = 2. difference(-) of the numbers is 2
now we add the two equations
x + x + y - y= -8 + 2
2x = -6
x = -6/2. = -3
substitute value of x in second equation to get y
-3 - y = 2
-y = 2 + 3
-y = 5
y = -5

What is the surface area of the figure?
9514 1404 393
Answer:
B. 24 cm²
Step-by-step explanation:
The formula for the area of a triangle is ...
A = 1/2bh
Here, you have a base of 4 cm and a height of 3 cm, so the area is ...
A = (1/2)(4 cm)(3 cm) = 6 cm²
__
The rectangle on the right is 3+1.5 = 4.5 cm high, and 8 -4 = 4 cm wide. Its area is ...
A = WH
A = (4 cm)(4.5 cm) = 18 cm²
The total area is the sum of the areas of the parts:
total area = triangle area + rectangle area
total area = 6 cm² + 18 cm² = 24 cm²
Pythagorean Theorem: a^2 + b^2 = c^2

plz help will mark brainliest if correct answer only
Answer:
18
Step-by-step explanation:
All I did was count the lines on the coordinate grid between -12 and 6. I was counting by 2's because the grid itself is counting by 2's
========================================================
Explanation:
If you start at 6, and count the number of spaces to get to -12, you should count out 18 spaces.
Or you could start at -12 and move to 6 to move 18 spaces to the right. Keep in mind each tickmark represents 2 spaces.
--------------
You could also think of it like this:
Place point A at -12, B at 0, C at 6
The distance from A to B is 12 units. The distance from B to C is 6 units. In total we have AB+BC = 12+6 = 18 units from A to C.
----------------
Or you could use absolute value and subtraction
Let P = -12 and Q = 6
We could say
|P - Q| = |-12-6| = |-18| = 18
or
|Q - P| = |6 - (-12)| = |6 + 12| = |18| = 18
The order of subtraction doesn't matter as long as you apply absolute value. Absolute value represents distance from 0 on a number line, so absolute value is never negative.

Find the area of each composite figure. Use 3.14 for π. Round to the nearest tenth if necessary. Whats the correct label?
Step-by-step explanation:
Square= bh
Square= 2×2=
half-circle = 1/2Pi*r×r
half-circle 2 = 1/2Pi*r×r
We would put 1/2 for the half-circle because its half of a circle. And we square it because where finding area. The middle is square, and the two up top is half a circle. Hope that helps :D
