Ava, Zoe and Logan went to the market to buy some presents for a friend's birthday. The three of them
together spent $720. If Logan spent twice as much Zoe did and Zoe spent $40 less than Ava did, how

a + z + l = 720
l = 2z = 2a - 80

A number has three digits: 1, 4, and 1.
To the nearest hundred, the number rounds to 400. What is the number?
Answers
Answer:
411
Step-by-step explanation:
Because it has a 4 , 1 , and a 1
meaning the first number can't be 1 so it is automatically a 4.
and then the only 2 numbers left is 2 one's so you have to put them in their also automatically and 4 is asking 1 to round up can it.
411 can't round up,it would round down because 1 is 4 and below so it can't go up and goes down.
so 4 1 1 can't go up the number would have to be 450 to go to 500 but because it is 411 it goes down to 400 because it is rounded to 400.

By bisector theorem: the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite angle. It equates their relative lengths to the relative lengths of the other two sides of the triangle
y/8 = 8/2
y = 32 .... sum of the length of 2 sides of triangle must be larger than the 3rd side, 8+2+8 = 18 < 32
y can only has a value < 18
If we use Law of Sines also get y = 32 ... not forming a triangle

A turtle and a snail start moving towards each other when they are 200 feet apart. The turtle is running at a speed of T feet per minute, and the snail is moving at a speed of S feet per minute. How fast are they approaching each other?
Answers
Answer:
200/T+S min
Step-by-Step Explanation:
Given:
Distance between turtle and snail=200 feetSpeed of turtle=T ft/minSpeed of Snail=S ft/minTo find:
Let time=tAfter t min they will meet to each other.We know that | Distance = Speed * Time |
Using the formula,Distance covered by turtle in time t=Tt ftDistance covered by snail in time t=St ftAccording to question,Tt + St = 200t (T + S) = 200t = 200/T+S minTime taken by them in approaching to each other = 200/T+S min
Find the area of the following shapes.
Area = __ mm^2
Answers
Answer:
Formulae used:
Area of a rectangle = width × length
Area of a triangle = 1/2 × base × height
Area of blue shape:
Area of rectangle + area of triangle
= (9 × 15) + (1/2 × (15 - 9) × 15)
= 135 + (1/2 × 6 × 15)
= 135 + 45
= 180 mm²
Area of yellow shape:
area of rectangle AHPB + area of rectangle GFQP + area of rectangle EDCQ
= (4 × 12) + (6 × (12 - 9)) + (4 × 12)
= 48 + (6 × 3) + 48

Mulberry Elementary has a playground in the shape of a rectangle.
The length is 5.5 meters
The width is 3.2 meters
Over the summer, the school will increase both the length and the width of the playground by 40% each.
Part A:
What will be the perimeter, in meters, of the enlarged playground? Enter your answer as a decimal with a hundredths place value.
Part B:
By how many square meters will the area of the playground increase? Enter your answer as a decimal with a thousandths place value.
Answers
The perimeter of the enlarged playground is 24.36 meters, and the increase in area is 16.9 m²
What is an area?
An area is the amount of space occupied by a two dimensional shape or object. The area of a rectangle is:
Area = length * width
Given that length = 5.5 m, width = 3.2 m
Hence:
Area = 5.5 * 3.2 = 17.6 m²
Perimeter = 2(length + width) = 2(5.5 + 3.2) = 17.4 m
There is an increase in both the length and the width of the playground by 40% each. Hence:
New length = 1.4 * 5.5 = 7.7 m, new width = 1.4 * 3.2 = 4.48 m
Area = 7.7 * 4.48 = 34.5 m²
Perimeter = 2(length + width) = 2(7.7 + 4.48) = 24.36 m
Increase in area = 34.5 m² - 17.6 m² = 16.9 m²
The perimeter of the enlarged playground is 24.36 meters, and the increase in area is 16.9 m²

Answers
Answer:
Change the mixed numbers into an improper fraction:
[tex]2\frac16 \div 2\frac12=\dfrac{2 \times 6+1}{6}\div \dfrac{2 \times 2+1}{2}=\dfrac{13}{6}\div \dfrac{5}{2}[/tex]
Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. (Reciprocal is when you swap the numerator and denominator). Therefore,
[tex]\dfrac{13}{6}\div \dfrac{5}{2}=\dfrac{13}{6}\times\dfrac{2}{5}[/tex]
Now we simply multiply the numerators and the denominators:
[tex]\dfrac{13}{6}\times\dfrac{2}{5}=\dfrac{13 \times 2}{6\times 5}=\dfrac{26}{30}[/tex]
We can now reduce the fraction to its simplest form by dividing the numerator and denominator by 2:
[tex]\dfrac{26}{30}=\dfrac{26\div 2}{30 \div 2}=\dfrac{13}{15}[/tex]
Answer:
[tex]\frac{1}{3}[/tex]
Step-by-step explanation:
I'll assume it is [tex]\frac{21}{6}[/tex]÷[tex]\frac{21}{2}[/tex]
Not so sure if it is that or in mixed form
The division sign will become multiplication sign when two becomes the numerator and 21 becomes the denominator

21 will cancel out leaving [tex]\frac{2}{6}[/tex]
