Answer:
x = 29
Step-by-step explanation:
Take the smallest integer as x. The next one as (x+1) and the last one as (x+2)
x + (x+1) + (x+2) = 90
x + x + x + 3 = 90
3x = 87
x = 29
Hence, x = 29

Tomas bought 2.4 pounds each of apples and pears. The apples cost $1.65 a pound and the pears cost $2.25 a pound. Tomas split the cost of the apples and pears evenly with his 3 siblings. How much should each of them pay for the apples and pears?
Answer:
$2.34
Step-by-step explanation:
The total cost is the sum of the number of pounds multiplied by the cost per pound for each of the items purchased. Each of the four equal shares of the cost will be 1/4 of the total cost.
__
The distributive property can be used to simplify the problem.
total cost = cost of apples + cost of pears
share cost = 1/4(total cost) = 1/4((2.4 lb)($1.65/lb) +(2.4 lb)($2.25/lb))
share cost = (1/4)(2.4)($1.65 +2.25) = 0.6($3.90)
share cost = $2.34
Each of them should pay $2.34 for the apples and pears.
You can use the surface area formula for a right cone to find the surface area
of an oblique cone.
A. True
B. False
Answer:
False
Step-by-step explanation:
False. Both surface area cannot be find using the same formula.
What is Surface Area?The area of a three dimensional object on it's outer surface is called the surface area of the object.
Right cone is a cone where the axis of the cone is perpendicular to the base .
Whereas, oblique cone has the axis of cone not perpendicular to the base.
Base area would be same for both right and oblique cones.
But the lateral surface area will be different.
Hence the surface area will be different.
Hence the surface area formula for a right cone is not same to find the surface area of an oblique cone.

So I got it wrong in my homework how do i translate it?
To translate something:
⇒ is to write out the equations
Let's examine what information this problem gives us:
Mrs. Albert has $400 ⇒ Total money = 400Mrs. Albert bought two adult tickets at $62.50 each⇒ with '2' being the number of adults tickets
⇒total charge from purchasing adult tickets = 2 * 62.5 = 125
Each child ticket costs $42.5⇒ with 'x' being the number of child tickets bought
⇒total charge from purchasing child tickets = 42.5x
Since the sum of total charge from purchasing adult tickets and total charge from purchasing child tickets is equal to 400:
⇒ 42.5x + 125 = 400 <== translated form
Let's solve:
[tex]42.5x+125=400\\42.5x=275\\x=6.47[/tex]
Since we can only buy whole tickets:
Mrs. Albert could have bought at most 6 child tickets
Answer: Mrs. Albert can bring 6 kids

HELPPPPP I NEED TO FINISH THIS MATH HOMEWORK BUT IM STUCK ON A QUESTION ( its number 4 not the one above)
Answer:
$27.85
Step-by-step explanation:
I think what it means by outstanding charge is that there is something else he also needs to pay that he hasn't input yet. So, going off of that logic,
20+7.85 = 27.85, to find the amount he should pay for both charges to not create another bank fee.
Which values of x and y would make the following expression represent a real number? (4 5i)(x yi) x = 4, y = 5 x = –4, y = 0 x = 4, y = –5 x = 0, y = 5
The product will be a real number when x = 4 and y = -5.
Which values of x and y should we use?We have the product of complex numbers:
[tex](4 + 5i)*(x + yi)[/tex]
We want this to be a real number, then the second complex number must be the complex conjugate of the first one, so we must have:
[tex](x + yi) = (4 - 5i)[/tex]
Now, if we take the product, we get:
[tex](4 + 5i)*(4 - 5i)\\\\4*4 - 4*5i + 4*5i - (5*5)*i^2 = 16 + 25 = 41[/tex]
So we can see that the outcome is a real number.
Then we must have x = 4 and y = -5.

Find mQTS⌢, m∠RQS and mQS⌢.
If the measure of the angle ∠RQT is 125°. Then the measure of the angles ∠RQS and ∠SQT will be 44° and 81°.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
If the measure of the angle ∠RQT is 125°. Then the measure of the angles ∠RQS and ∠SQT will be
Then we have
∠RQS + ∠SQT = 125°
(3x - 10)° + (4x + 9)° = 125°
7x - 1 = 125°
7x = 126°
x = 18°
Then the measure of the angle ∠RQS will be
∠RQS = 3 × 18 - 10
∠RQS = 44°
Then the measure of the angle ∠SQT will be
∠SQT = 4 × 18 + 9
∠SQT = 81°

Answer:
3
Step-by-step explanation:
Using Pythagoras formula
h^2 = (root under) p^2 +b^2
or, h^2= 20^2 + 21^2
or, h^2= 400+441
or, h^2= 841
or, h= (root under) 841
Therefore h= 29

the area of a whole circle (360°) is

Determine the equation of the perpendicular bisector of AB and state the coordinates of the point where the perpendicular bisector meets or intersects with the y-axis.
Gradient: -1
Midpoint : [5,1]
Coordinates for A: [3,5] , B: [7,1]
Answer:
the equation will be in the form of:
y = -x + b
To find be take any point on the line. Hence we have (5,1) which is the midpoint where the line meets.
Therefore, substitute (5,1) in the above equation:
1 = -5 + b
b = 6
So the question of the line will be:
y = -x + 6

Solve the following equation. Show all your work.
(x/(x−2))+((x−1)/(x+1))=−1
Answer:
[tex]\displaystyle x = 0 \text{ and } x = 1[/tex]
Step-by-step explanation:
We are given and asked to solve the equation:
[tex]\displaystyle \frac{x}{x-2} + \frac{x-1}{x+1} = -1[/tex]
We can first remove the rational expressions by multiplying both sides of the equation by its LCM (in this case, by (x - 2)(x + 1)):
[tex]\displaystyle (x-2)(x+1) \left( \displaystyle \frac{x}{x-2} + \frac{x-1}{x+1}\right) = -1(x-2)(x+1)[/tex]
Simplify:
[tex]\displaystyle x(x+1)+(x-1)(x-2) = -(x-2)(x+1)[/tex]
Expand and isolate:
[tex]\displaystyle \begin{aligned} (x^2 + x) + (x^2 - 3x + 2) & = -(x^2 -x -2) \\ \\ 2x^2 - 2x + 2& = -x^2 + x + 2 \\ \\ 3x^2 - 3x & = 0 \end{aligned}[/tex]
Hence solve for x:
[tex]\displaystyle \begin{aligned} 3x(x - 1) & = 0 \\ \\ x & = 0\text{ or } x = 1\end{aligned}[/tex]
In conclusion, the solutions of the equation are x = 0 and x = 1.

AB/BC = AE/ED is less than or eqauls ED = BC×AE/AB
so
ED = 5×26/20 = 130/20 = 6.5 cm

AB/AC = BE/CD => BE = AB×CD/AC

BE = 20×18/25 = 360/25 = 14.4 cm
A store buys 17 sweaters for $68 and sells them for $561. How much profit does the store make per sweater?
He makes a profit in total of $8381
The store makes a profit of $29 per sweater.
Here, we have to calculate the profit per sweater, we need to find the difference between the selling price and the cost price (purchase price) of each sweater.
Given:
Number of sweaters bought = 17
Cost of buying 17 sweaters = $68
Selling price of 17 sweaters = $561
Profit per sweater = Selling price per sweater - Cost price per sweater
First, calculate the cost price per sweater:
Cost price per sweater = Total cost / Number of sweaters
Cost price per sweater = $68 / 17
Cost price per sweater = $4.
Now, calculate the profit per sweater:
Profit per sweater = Selling price per sweater - Cost price per sweater
Profit per sweater = $561 / 17 - $4
Profit per sweater = $33 - $4
Profit per sweater = $29.
The store makes a profit of $29 per sweater.

A.
The graph of h is the graph of g vertically shifted up 3 units.
B.
The graph of h is the graph of g horizontally shifted right 3 units.
C.
The graph of h is the graph of g horizontally shifted left 3 units.
D.
The graph of h is the graph of g vertically shifted down 3 units.
Answer:
B
Step-by-step explanation:
given f(x) then f(x ± a) is a horizontal translation of f(x)
• if + a , then a shift to the left of a units
• if - a then a shift to the right of a units
h(x) = g(x - 3)
then h is the graph of g shifted right 3 units
