Malala is following this recipe for bread rolls.
She uses 500ml of water.
How much of each ingredient does she use?
Recipe: Makes 15 bread rolls.
480g flour
12g salt
6g yeast
30ml oil
600ml water
Answer & Step-by-step explanation:
500 is roughly about 83% of 600 (we know this because 500/600 = 0.833)
If she is following the recipe, then if she is using 83% of the water shown in the recipe, then she will be putting in about 83% of every ingredient.
480 * 0.83 = 398g flour
12 * 0.83 = 9.96g salt
6 * 0.83 = 4.98g yeast
30 * 0.83 = 24.9ml oil
and 500ml water

Answer:
x = 30
Step-by-step explanation:
If A and B were parallel, then 2x + 50 and 5x - 80 are same- side interior angles and sum to 180° , then
2x + 50 + 5x - 80 = 180
7x - 30 = 180 ( add 30 to both sides )
7x = 210 ( divide both sides by 7 )
x = 30

Show and explain all of the steps used in order to simplify the following rational expression 3x^(2)-3x / 3x^(3)-6x^(2)+3x to 1 / x-1.
Answer:
3x^2 + x^4 - x^3 + 3 - 6x
Step-by-step explanation:
Find Least Common Multiplier of 3x^(2)-3x / 3x^(3)-6x^(2)+3x to 1 / x-1
3x^2 - 3 . x/3 x^3 - 6x^2 + 3x
Apply exponent rule: a^b + c = a^b a^c
x^2 = xx, x^3 x/3 = xx^2, x^2 = xx
= 3xx - 3xxx - 6xx + 3x
Rewrite -6 as 2 . 3
= 3xx - 3xxx + 2 . 3xx + 3x
Factor out common term 3x
= 3x(x - x^2(x/3) -2x + 1)
= 3x(- x^3/3 - x + 1)
Multiply each factor with the highest power:
(- x^3/3 - x + 1) . 3 . (1/x - 1\) . x
Simplify
3x^2 + x^4 - x^3 + 3 - 6x
Melinda walked to the mall at 4 miles per hour and then rode back home in a bus at 24 miles per hour. If her total traveling time was 14 hours, how far was it to the mall?
Given:
Melinda walked to the mall at 4 miles per hour and then rode back home in a bus at 24 miles per hour.
Total traveling time was 14 hours.
To find:
The distance between Melinda's house and mall.
Solution:
Formula used:
[tex]Time=\dfrac{Distance}{Speed}[/tex]
Let x miles be the distance between Melinda's house and mall.
Melinda walked to the mall at 4 miles per hour. So, the time taken by Melinda is [tex]\dfrac{x}{4}[/tex] hours.
Speed of bus is 24 miles per hour. So, the time taken by bus is [tex]\dfrac{x}{24}[/tex] hours.
Total traveling time was 14 hours.
[tex]\dfrac{x}{4}+\dfrac{x}{24}=14[/tex]
[tex]\dfrac{6x+x}{24}=14[/tex]
[tex]7x=14\times 24[/tex]
Divide both sides by 7.
[tex]\dfrac{7x}{7}=\dfrac{14\times 24}{7}[/tex]
[tex]x=2\times 24[/tex]
[tex]x=48[/tex]
Therefore, the mall is 48 miles far from Melinda's house.
A group of 2 adults and 4 children spent $38 on tickets to a museum. A group of 3 adults and 3 children spent $40.50 on tickets to the museum. Based on this information, how much is an adult ticket, and how much is a child ticket?
Answer:
adult $8.00
child $5.50
Step-by-step explanation:
Let the price of 1 adult ticket = x.
Let the price of 1 child ticket = y.
2x + 4y = 38
3x + 3y = 40.5
Multiply the first equation by 3. Multiply the second equation by -2. Then add them.
6x + 12y = 114
(+) -6x - 6y = -81
-----------------------------
6y = 33
y = 33/6
y = 5.5
2x + 4y = 38
2x + 4(5.5) = 38
2x + 22 = 38
2x = 16
x = 8
Answer:
adult $8.00
child $5.50
Answer:
An adult ticket is $8.00 and a child's ticket is $5.50.
Step-by-step explanation:
We form a system of 2 equations and solve them.
Let a be the price of adult ticket and c the price of a child's.
2a + 4c = 38 (A)
3a + 3c = 40.5 (B)
Multiply equation A by 3 and equation B by -2:
6a + 12c = 114
-6a - 6c = -81 Adding these 2 equations:
0 + 6c = 33
c = 33/6 = 5.5.
Now we substitute for c in equation A:
2a + 4(5.5) = 38
2a = 38 - 22
2a = 16
a = 6.
Let's now check these results by substitution in equation B:
3a + 3c = 40.5
3(8) + 3(5.5) = 24.0 + 16.5 = 40.5
- so it checks out.

I have seen the results but I got one right but in that there were 2 b n the perimeter of rectangle is 2(l+b)
day after tomorrow my papper is there pls help me
Answer:
1976 cm 2Step-by-step explanation:
Let the length of the rectangle be=l
So, breadth is b=l−14
Perimetre= 2(l+b)=2(l+l−14)=180 cm
⟹4l−28=180cm
⟹l=52cm
And, b=52−14=38cm
Hence, Area=l×b=52×38=1976cm

For males in a certain town, the systolic blood pressure is normally distributed with a
mean of 110 and a standard deviation of 6. Using the empirical rule, what percentage
of males in the town have a systolic blood pressure
between 92 and 128?
Answer:
99.7%
Step-by-step explanation:
Note that 92 and 128 are 3 standard deviations from the mean
The emperical rule or the 68–95–99.7 rule states that 68% of outcomes are wihtin 1 standard deviation from the mean
95% of outcomes are within 2 standard deviations from the mean
99.7% of outcomes are within 3 standard devations from the mean
This is 3 standard deviations so the answer is 99.7
An old-fashioned Chinese restaurant offers a family dinner where you get to choose one dish from “column A” (which has 8 dishes), one dish from “column B” (which has 10 dishes) and one dish from “column C” (which has 5 dishes). How many different family dinners can be chosen?
There are ___ possible dinners.
Answer:
There are 400 possible dinners.
Step-by-step explanation:
There are 8 dishes to choose from column A. For each of these 8 dishes, there are 10 dishes to pair with. For each of these 10 dishes, there are 5 dishes to go with from column C.
Therefore, multiply to get [tex]8\cdot 10\cdot 5=\boxed{400}[/tex] possible dinners.
*Note: Since the order of which you choose is fixed, we do not need to account for rearrangements of the same three dishes.
Cuál es el valor líquido sobre un documento con valor nominal de $25,000 que vence dentro de 3 meses a una tasa de descuento simple del 9% anual?
Respuesta:
$ 24437,5
Explicación paso a paso:
Dado :
Valor nominal = $ 25000
Tasa, r = 9% = 0.09
Período, t = 3 meses = 3/12
Usando la relación:
Equidad en el documento = Valor nominal (1 - rt)
Equidad en el documento = $ 25000 (1 - 0.25 * 0.09)
$ 25000 (1 - 0.0225)
$ 25000 (0,9775)
= $ 24437.5
La equidad en el documento = $ 24437.5

A bus travels 90 km in 1.5 hours (with a constant speed). How far can it travel in 7.2 hours (with the same speed)?
Answer:
distance=90km
time=1.5h
speed of the bus=distance /time
speed of the bus=90km/1.5h
speed of the bus=60km/h
therefore if 1.5h=60km/h
then 7.2h=(7.2x60)/1.5 =288km

Six teachers and 12 students volunteer for a committee to discuss extra-curricular activities. How many committees of 5 people can be made if:
a) there must be exactly 3 students on the committee
b) there must be at least one teacher and at least one student on the committee
Answer:
a) 11,880
b) 7,770
Step-by-step explanation:
The number of teachers that volunteer = 6 teachers
The number of students that volunteer = 12 students
The number of people in the committee = 5 people
a) The exact number of student on the committee = 3 student
Therefore, the number of teachers in the committee of 5 = 5 - 3 = 2
The number of teachers in the committee = 2 teachers
We get;
The number of committees that can be made = ₁₂C₃ × ₆C₂ = 792×15 = 11,880
b) When there is at least one teacher and at least one student on the committee, we have;
₁₂C₄ × ₆C₁ + ₁₂C₃ × ₆C₂ + ₁₂C₂ × ₆C₃ + ₁₂C₁ × ₆C₄ = 7,770
The number of committees having at least one teacher and at least one student = 7,770
