Answer:
Luisa has $18
Step-by-step explanation:
Let us solve the question
∵ Carlos has $24
∵ Carlos has 1 [tex]\frac{1}{3}[/tex] as much money as Luisa has
→ Let Luisa has x dollars
∵ Luisa has x dollars
∴ Carlos money = 1 [tex]\frac{1}{3}[/tex] × x
∴ Carlos money = 1 [tex]\frac{1}{3}[/tex] x
→ Change the mixed number to an improper fraction
∵ 1 [tex]\frac{1}{3}[/tex] = [tex]\frac{1(3)+1}{3}[/tex] = [tex]\frac{4}{3}[/tex]
∴ Carlos money = [tex]\frac{4}{3}[/tex] x
→ Substitute the Carlos money by 24
∵ 24 = [tex]\frac{4}{3}[/tex] x
→ Multiply both sides by 3
∵ 24 × 3 = 4x
∴ 72 = 4x
→ Divide both sides by 4
∴ 18 = x
∴ Luisa has $18

A man sold a fan for Rs. 400. Find the cost price if he incurred a loss of 15%.
Answer:
Cost price of the fan is [tex]\text {Rs. 470.59}[/tex].
Step-by-step explanation:
Given: A man sold a fan for [tex]\text{Rs.}\:400[/tex]. He incurred a loss of [tex]15\%[/tex].
To find: The cost price of the fan
Solution:
We have,
Selling price, S.P., of the fan [tex]= \text{Rs.} 400[/tex]
Loss [tex]=15\%[/tex]
We know that [tex]\text {Loss\%}=\frac{\text{C.P.-S.P.}}{\text{C.P.}}\times100\%[/tex]
Now let the C.P. of the fan be [tex]\text{Rs.} \:x[/tex]
So, [tex]15=(\frac{x-400}{x})\times 100[/tex]
[tex]\implies 15x=100x-40000[/tex]
[tex]\implies 100x-15x=40000[/tex]
[tex]\implies 85x=40000[/tex]
[tex]\implies x=\frac{40000}{85}[/tex]
[tex]\implies x= 470.59[/tex]
Hence, the cost price of the fan is [tex]\text {Rs. 470.59}[/tex].
The figure below depicts a triangle formed by the labeled
vertices. If each vertex point of the triangle is multiplied
by what would be the area of the resulting triangle?
(Triangles, Book 2)
(3, 3)
0.0)
09
0 13.5
0 15
18
O 27
9514 1404 393
Answer:
(b) 13.5
Step-by-step explanation:
The upper vertex would be ...
3/2(3, 3) = (4.5, 4.5)
and the right vertex would be ...
3/2(4, 0) = (6, 0).
The base of the larger triangle would be 6, and its height would be 4.5. Then the area is ...
A = (1/2)bh
A = (1/2)(6)(4.5) = 13.5 . . . area of dilated triangle

An airplane descends 1.5 miles to an elevation of 6.05.Find the elevation of the plane befor its descent the intial elevation of the plane was blank miles
Answer:
7.55 miles
Step-by-step explanation:
Given that :
Distance of descent = 1.5 miles
New elevation point after descent = 6.05 miles
The initial elevation of the plane before descent will be :
New elevation point after descent + Distance of descent
(6.05 miles + 1.5 miles)
= 7.55 miles

Answer:
4 sqrt 2
Step-by-step explanation:
Answer:
4 sqrt(2)
Step-by-step explanation:
This is a special triangle 45, 45, 90 therefore you just multiply the sides by sqrt(2) to find the hypotenuse so it will be 4 sqrt(2)
Another way to do it is by Pythagorean triangle which will still lead to 4 sqrt(2)

Answer: 3:2
Step-by-step explanation:
the base ratio of unused tape to used tape is 24:16.
then we have to simplify,
both 16 and 24 can be divided by eight,
24 divided by eight is 3
16 divided by eight is 2
therefore, our simlpified ratio is 3:2

PLZZZZZZ HELP ME
Step-by-step explanation:
The coordinate plane is a two-dimension surface formed by two number lines. One number line is horizontal and is called the x-axis. The other number line is vertical number line and is called the y-axis. The two axes meet at a point called the origin. We can use the coordinate plane to graph points, lines
5. x2 +5x-4
Discriminate
Answer:
D = 41
Step-by-step explanation:
y = ax² + bx + c
The discriminant D = b² - 4ac tells the types of roots the equation has.
If D < 0 , then quadratic equation has no real roots, has two imaginary roots.
If D = 0 , then quadratic equation has one real root.
If D > 0 , then quadratic equation has two distinct real roots.
~~~~~~~~~~~~
x² + 5x - 4
a = 1, b = 5, c = - 4
D = 5² - 4(1)(- 4) = 25 + 16 = 41

Little billy wants to buy a pineapple upside down came. The cakes are 2 days old so they are 70% off! The original price is $20. What is the sale price
Answer:
$6
Step-by-step explanation:
Original price of the pineapple = $20
Percentage off = 70%
Amount discounted = 70% of $20
Amount discounted = 0.7 * 20
Amount discounted = $14
Sale price = Original price - Discount
Sale price = $20 - $14
Sale price = $6
Hence the sale price was $6

Clara found the product of 3 – 6y2 and y2 + 2. Her work is shown below.
(3 – 6y2)(y2 + 2) = 3(y2) + (–6y2)(2)
= 3y2 – 12y2
= –9y2
Is the student’s work correct?
Answer: No the students work is not correct. Because you are using distribution. Which means that 3 has to multiply the y2 and 2 not just the y2! And after you distribute it you need to simplify!
Step-by-step explanation:
Answer:
(3 – 6y²)(y² + 2) = - 6y⁴ - 9y² + 6
Step-by-step explanation:
Given the expression
3-6y² and y²+2
We have to find the product of 3-6y² and y²+2
Clara's Solution:
(3 – 6y²)(y² + 2) = 3(y²) + (–6y²)(2)
= 3y² – 12y²
= -9y²
NO!
The student's work is INCORRECT!
Clara did not imply the correct distribution of multiplying the terms in the first step.
Here is the correct solution:
(3 – 6y²)(y² + 2) = 3(y²) + (–6y²)(2) + (3)(2) + (–6y²)(y²)
= 3y² – 12y² + 6 - 6y⁴
= - 6y⁴ - 9y² + 6
Therefore,
(3 – 6y²)(y² + 2) = - 6y⁴ - 9y² + 6
A class trip is planned for a cinema visit.
1/4 of the people walk to it.
1/3 of the people, get the bus.
The remaining 60 people get a lift in a car.
Calculate the number of pupils who get the bus and who walk to the cinema.
Answer: 48 pupils get the bus to the cinema and 36 pupils walk to the cinema.
Step-by-step explanation:
Let's suppose that there are a total of N pupils.
We know that N/4 walk to the cinema.
We know that N/3 get the bus to the cinema.
And the remainder is equal to 60 people.
Then:
N - N/4 - N/3 = 60
N*(1 - 1/4 - 1/3) = 60
N( 12/12 - 3/12 - 4/12) = 60
N*( 5/12) = 60
N = (12/5)*60 = 144
Then the number of pupils that walk to the cinema is N/4, or:
144/4 = 36
And the number of pupils that get the bus is N/3, or:
144/3 = 48.
