Miss McKee has 1,183 gold stickers. She wants to give the same number of stickers to each of her 30 students. If she gives away as many stickers as she can, how many stickers will be left over?
Answer:
If she gives away as many stickers as she can, stickers left = 13
Step-by-step explanation:
Total number of gold stickers = 1183
Total number of students = 30
So, each student will get = [tex]\frac{1183}{30}[/tex] = 39.433
As the gold stickers cannot be given in integer form
So , each student get 39 stickers.
So, 30 students get = 30×39 = 1170
So Left over stickers = 1183 - 1170 = 13
Ashley spent $35 on her meal at Longhorn Steakhouse and leaves a $6.30 tip. What percent tip did Ashley leave?
Answer:
18%
Step-by-step explanation:
Given that,
Ashley spent $35 on her meal at Longhorn Steakhouse and leaves a $6.30 tip.
We need to find what percent tip did Ashley leave. The percentage of tip leaved by Ashley is given by :
[tex]\%=\dfrac{6.3}{35}\times100\\\\\%=18\%[/tex]

Kiara has a box that is 20 centimeters long, 5 centimeters wide, and 10 centimeters deep. She wants to fill the box with other packages that
are 5 centimeters long, 1 centimeter wide, and 4 centimeters deep.
What is the greatest number of packages that she can put in the box without it overflowing?
Answer:
50 packages
Step-by-step explanation:
Area of the box: A= (l)(w)(h)
=(20)(5)(10)
=1000cm^3
Area of the package: A= (5)(1)(4)
=20cm^3
1000/20=50 packages
50 number of packages that she can put in the box without it overflowing
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given that Kiara has a box that is 20 centimeters long, 5 centimeters wide, and 10 centimeters deep.
Length=20
Width=5
Height=10
Area of cube=Length×width×height
=20×5×10
=1000 cm³
The other packages is 5 centimeters long, 1 centimeter wide, and 4 centimeters deep.
Area=5×1×4
=20 cm³
We need to find the greatest number of packages that she can put in the box without it overflowing
To find this we have to divide 1000 by 20
1000/20=50
Hence, 50 number of packages that she can put in the box without it overflowing

Rewrite in scientific notation 0.000357
Answer:
3.57 x 10^-4
Step-by-step explanation:
see how many places you have to move the decimal to create a number that is greater than or equal to one, in this case that number would be 3.57
we had to move the decimal four places to get it there
when moving to the left the exponent is negative
when moving to the right the exponent is positive
Answer:
3.57 × 10-4
Step-by-step explanation:
All numbers in scientific notation or standard form are written in the form
m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.
To convert 0.000357 into scientific notation, follow these steps:
Move the decimal 4 times to right in the number so that the resulting number, m = 3.57, is greater than or equal to 1 but less than 10
Since we moved the decimal to the right the exponent n is negative
n = -4
Write in the scientific notation form m × 10n
= 3.57 × 10-4
Therefore,
3.57 × 10-4 is the scientific notation form of 0.000357 number and 3.57e-4 is the scientific e-notation form for All numbers in scientific notation or standard form are written in the form
Gina has 5 2/8 feet of silver ribbon and 3 6/8 of gold ribbon. How much more silver ribbon does Gina have than gold ribbon.
Answer: we are simply to subtract the length of the gold ribbon which is 2 4/6 ft from the length of the silver ribbon, 5 2/6 feet. Mathematically,
5 2/6 feet - 2 4/6 feet = 8/3 feet
Therefore, Gina has 8/3 feet more of the silver ribbon than the golden ribbon.
In right triangle ABC, AC = 4 and BC = 5. A new triangle DEC is formed by connecting the midpoints of AC and BC. What is the area of triangle ABC? *
You can use the Pythagoras theorem to find the height of the triangle given and then by the height and the base of the triangle, you can find its area.
The area of the triangle ABC is 6 square units.
Right angled triangle:A right angled triangle is a triangle having one of its angle with measure of 90 degrees.
The slant side of that triangle is called Hypotenuse and it is the longest side in that triangle.
The Pythagoras theorem:If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
[tex]|AC|^2 = |AB|^2 + |BC|2[/tex]
How to find the area of given right angled triangle ABC?Refer to the diagram attached below.
Since we have right angle at angle A, and we have
|AC| = 4 units, |BC| = 5 units, let |AB| = [tex]x[/tex] units, then
[tex]|AC|^2 + |AB|^2 = |CB|^2\\4^2 + x^2 =5^2\\x ^2 = 25-16\\x = \sqrt{9} = 3 \text{\:(Positive root since x is length which is non negative quantity)}[/tex]
Area of a triangle is half of its base times height.
Since the line AC s perpendicular to AB, thus we can take base as AB and height as AC, then we have:
[tex]Area = \dfrac{1}{2} \times |AC| \times |AB| = \dfrac{1}{2} \times 4 \times 3 = 6 \: \rm unit^2[/tex]
Thus,
The area of the triangle ABC is 6 square units.

a line includes the points 2, 10 and 0, 2 what is its equation in slope intercept form
Answer:
y = -4x + 2
Step-by-step explanation:
y = mx + b ( slope-intercept)
1. Find Slope:
[tex]\frac{y^2 - y^1}{x^2 - x^1}[/tex]
Lets name 2 as y2 and 10 as y1. And 0 as x2 and 2 as x1.
[tex]\frac{2-10}{0-2}[/tex] = [tex]\frac{-8}{2}[/tex] = -4
m/slope = -4
2. Find y-intercept:
[tex]y = mx +b[/tex]
2 = -4(0) + b
= 2 = b
Y-intercept/b = 2
3. Put into slope-intercept form:
y = mx + b
= y = -4x + 2

Carter used 1 1/3 gallons of paint to paint 2/5 of a wall. How many gallons will it take to paint the whole wall? Show your reasoning with a diagram.
Answer:
3 1/3 gallons
Step-by-step explanation:
It is more helpful to think of the wall as 5 sections. if two sections used 4/3, by logic one section uses 2/3 (because 4/3 ÷ 2 = 2/3). since there are 5 sections, 2/3 × 5 you get 10/3. turn it into a mixed fraction and you get 3 1/3.
