olivia chooses the whole number she divides it by 4 then adds 8 she then divides this result by 2. her answer is 3.5. what number did she start with
Answer:
-8
Step-by-step explanation:
just do the promble backwards
3.5 times 2 = 6
6-8=-2
-2 times 4 = -8
or solve for x
x/ 4 + 8 /2=3.5
The difference of two numbers is 16. The greater number is 5 less than 4 times the smaller
number. Find the two numbers.
Answer:
x= 23
y=7
Step-by-step explanation:
x-y=16
4y-5=x
4y-5-y=16
3y-5=16 add 5 to both sides
3y=21 divide by 3 on both sides
y=7
x-7=16 substitute back in
x=23 added 7 to both sides
so x=23 and y=7
23-7=16

Work out the surface area of this cylinder.
Answer:
Step-by-step explanation:
Total surface = πr² + 2πrh
Surface area = 22/7 × 6 × 6 + 2 × 22/7 + 25
So 22/7 × 12 + 44/7 × 25
Therefore this will give us 37.71 + 157.14
Therefore the total surface area of the cylinder is 194.85 cm².
Hope this helps
Divide 3500 in the ratio 2: 2 : 3
Answer:
1000 : 1000 : 1500
Step-by-step explanation:
2 + 2 + 3 = 7
3500 ÷ 7 = 500
2 × 500 = 1000
2 × 500 = 1000
3 × 500 = 1500
1000 : 1000 : 1500
Answer:
1000 : 1000 : 1500
Step-by-step explanation:
you divide 3500 into 7 and find the answer = 500
then 500 x 2 = 1000,
500 x 3 = 1500
A square playground has an area of 400 square feet. What is the length of each side of the playground

The length of each side of the playground is 20 ft.
What is a Square?
Square in geometry is a special kind of rectangle with four equal sides and four right (90°) angles.
Given is a square playground has an area of 400 square feet.
Area of square playground = 400 ft².
Area of square is given by square of the length of its sides. If 'a' is the side of a square, then mathematically we can write -
A [S] = a²
Using the formula discussed above -
a² = 400
a = √400
a = 20 ft
Therefore, the length of each side of the playground is 20 ft.

A selection box contains four types
of sweets: 6 caramels, 7 chocolates,
4 bonbons and 3 nougats
What fraction are carame/s
b. What fraction are not caramels?
Answer:
3/10 are caramel 7/10 are not caramel
Step-by-step explanation:
First you need to work out the total of sweets that is 6+7+4+3=20 sweets. Now it says that there are 6 caramels so you need to put 6/20 which can be simplified to 3/10. For b you have to work out the fraction that is not caramel so for this you have to add up 7+4+3=14 put 14/20 this can be simplified to 7/10.

raise 6 to the 4th power, then find the difference of the result and p
Answer:
1296
Step-by-step explanation:
y = -x²+4
y = 2x+1
solve the system of equations
The solution of the equation as x= -1 then y= -1 and x= 3 then y = 7.
What is Equation?It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have equations y = -x²+4 and y = 2x+1.
So, 2x + 1 = -x²+4
x² - 4 -2x +1 = 0
x²-2x -3 = 0
Now splitting the mid term we get
x²-2x -3 = 0
x²-3x +x -3 = 0
x(x-3 ) + 1 (x-3)= 0
(x+ 1) (x-3) = 0
x= -1 or 3.
and, when x= -1 then y= -1
when x= 3 then y = 7.

if angle 1= 135, what is the measure of angle 2, and give your reason. Use the picture i used
Answer:
The measure of m∠2 is:
m∠2 = 45°Step-by-step explanation:
A straight angle is an angle equal to 180 degrees. It is called straight because it appears as a straight line.
Given
The angle ∠ 1 = 135°.
It is clear that angles ∠ 1 and ∠ 2 lie on a straight line.
We know that a straight line is basically a straight angle i.e. 180°.
Thus,
The sum of angles ∠ 1 and ∠ 2 will be 180°.
i.e.
m∠1 + m∠2 = 180°
substitute m∠1 = 135° in the equation
135° + m∠2 = 180°
subtract 135° from both sides
135° + m∠2 - 135° = 180° - 135°
m∠2 = 45°
Therefore, the measure of m∠2 is:
m∠2 = 45°i need help with this question ASAPP

Find the measure of the exterior angle.
Answer:
120 degrees
Step-by-step explanation:
Because the triangle is a right triangle, it can be either a 45,45,90 triangle or a 30,60,90 triangle. I tested this problem with each scenerio, and I believe that it is a 30, 60, 90 triangle, with the top angle being 30 degrees, thus, making x=30. For the exterior angle, we'd multiply 4 by 30 to get 120 degrees.
I checked my answer by adding 120 to 60 (that's the degrees of the right hand corner of the triangle), which added to 180 degrees (aka a flat line), which verifies my answer.

Answer:
Step-by-step explanation:
If a boat has the speed = 15 miles per hour
Let the speed of the river = v miles per hour
If the boat is moving down stream, that means boat is traveling with the stream of the river.
So the speed of the boat downstream = (15 + v) miles per hour
Since, speed of the river stream is added with the speed of the boat, it will reach the destination earlier than the expectation.
Solve for the value of w.
(w-8)°
(2W-1)º
Answer:
w=57
Step-by-step explanation:
The angles are supplementary because they are adjacent to one another and lies on a straight line
w-8+2w-1=180
Combine like terms
3w-9=180
Subtract 9 on both sides
3w=171
Divide 3 on both sides
w=57
