.Ahmed is making pancakes, his recipe uses 150g of flour for 8 pancakes. How much flour will he need to make 12 pancakes? Remember to give units in your answer.
Answer:
Ahmed needs 225g of flour to make 12 pancakes.
Step-by-step explanation:
With the information provided, you know that the recipe uses 150g of flour for 8 pancakes and you can use a rule of three to find the amount of flour needed to make 12 pancakes:
150g → 8 pancakes
x ← 12 pancakes
x=(150*12)/8= 225g
According to this, the answer is that Ahmed needs 225g of flour to make 12 pancakes.
Jaythen finds a shirt on sale for 10% off at a store. The original price was $20. Jaythen must also pay 8.5% sales tax. How much is the shirt before taxes? *
How much does Jaythen pay total for his shirt after taxes? *
Answer:
the shirt before taxes is $18. the shirt after taxes is 19.53
Step-by-step explanation:
you multiply 20x.10 and you'll get 2. so you subtract 2 from 20, that's $18.
to get taxes, you multpliply 18x.085 and you get $1.53.
you then add $1.53 to 18 and you get your total price of $19.53
Answer:
Before taxes, the shirt was $18. After taxes. the shirt is $19.53
Step-by-step explanation:
A group of cubes are arranged in a pattern with the same number of cubes in each row and column. There are 225
cubes in the shape. How many cubes are in one row?
A)
15
B)
25
0
56
D)
75
Given:
Total number of cubes = 225
Cubes are arranged in a pattern with the same number of cubes in each row and column.
To find:
The number of cubes in a row.
Solution:
Let the number of cubes in a row be x.
Since, cubes are arranged in a pattern with the same number of cubes in each row and column, therefore number of cubes in rows and columns are equal.
[tex]\text{Total cubes}=x\times x[/tex]
[tex]\text{Total cubes}=x^2[/tex]
Total number of cubes = 225
[tex]x^2=225[/tex]
Taking square root on both sides.
[tex]x=\sqrt{225}[/tex]
[tex]x=15[/tex]
So, the number of cubes in a row is 15.
Therefore, the correct option is A.

PLEASE HELP As a part-time job, ethan makes deliveries for a caterer. In addition to his weekly salary, he is also paid 16$ Per delivery. Last week, he made 5 deliveries and his total salary was $215. Write a linear equation to find Ethan's total weekly salary S if he makes d deliveries.
you know he made 5 deliveries for $16 each. 5*16=80. So to find his salary you have 215-80=$135.
So he makes $135 no matter what plus $16 times the number of deliveries.
so, S=16d+135
5x = 10 can someone help me
Answer:
X=2
Step-by-step explanation: To get a single
x
, divide
5
x
by
5
.
Whatever you do to one side of the equals sign, you must do to the other side. This means, to get the right answer, you must do
5
x
5
=
10
5
The
5
's on the left side of the equals sign cancel out so it would make
5x5=105
and then
x=105105
is equal to
2
so...
x=2
Answer: Hey user! x = 2.
Step-by-step explanation: Step 1: Divide both sides by 5.
5x /5 = 10 /5
x=2

Población de alces. Se introducen cíen alces en una reserva zoológica, cada uno de un año de edad. El número N(t) de animales vivos después de t años se predice mediante N(t) = 100(0.9) t Estima el número de animales vivos después de:
Answer:
El número de animales vivos después de 1, 5 y 10 años es 90, 60 y 35 respectivamente.
Step-by-step explanation:
Sabes que el número N(t) de animales vivos después de t años se predice mediante N(t) = 100*[tex]0.9^{t}[/tex]
Para estimar el número de animales vivos después de, por ejemplo, 1 año debes simplemente reemplazar el tiempo t por el tiempo correspondiente, en este caso 1 año:
N(1) = 100*[tex]0.9^{1}[/tex]
Resolviendo:
N(1) = 100*[tex]0.9^{1}[/tex]= 100*0.9= 90
De manera similar, podes estimar el número de animales vivos después de 5 y 10 años. Esto es, reemplazas t por 5 años:
N(5) = 100*[tex]0.9^{5}[/tex]= 100*0.59049= 59.049≅ 60
y t por 10 años:
N(10) = 100*[tex]0.9^{10}[/tex]= 100*0.3487= 34.86 ≅ 35
El número de animales vivos después de 1, 5 y 10 años es 90, 60 y 35 respectivamente.

Peter works as a delivery person for a bike shipping company. The graph shows a linear model for his
delivery times on different days.
(a) what is the equation of the line, first written in point-slope form and then written in slope- intercept form? show how you determined the equation.
(b) based on the linear model, predict how long it initially took peter to deliver his packages (y-intercept) approximately how much did his delivery time decrease per day (slope)? Complete sentences
Answer/Step-by-step explanation:
a. Using a point on the graph, (6, 12), and the slope of the line, we can first generate an equation in the point-slope form, given as [tex] y - b = m(x - a) [/tex], where,
m = slope, and (a, b) is a point on the line.
Using two points, (6, 12) and (3, 21), let's find slope, m.
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{21 - 12}{3 - 6} = \frac{9}{-3} = -3 [/tex]
Using a point (6, 12) and slope, m = -3, generate an equation in the point-slope form by substituting a = 6, b = 12, and m = -3 in [tex] y - b = m(x - a) [/tex].
✅Equation in point-slope form would be:
[tex] y - 12 = -3(x - 6) [/tex]
Rewrite this to make it be in the slope-intercept form, [tex] y = mx + b [/tex].
[tex] y - 12 = -3(x - 6) [/tex]
[tex] y - 12 = -3x + 18 [/tex]
Add 12 to both sides
[tex] y = -3x + 18 + 12 [/tex]
[tex] y = -3x + 30 [/tex]
✅The equation in slope-intercept form is [tex] y = -3x + 30 [/tex]
b. ✍️Based on the linear model, [tex] y = -3x + 30 [/tex], the 30 represents b = y-intercept.
✅Therefore, it took Peter 30 mins long initially to deliver his package.
✍️Based on the linear model, [tex] y = -3x + 30 [/tex], "-3" represents the slope.
✅Therefore, Peter's delivery time decreased 3 mins per day.
50 is 20% of what ? Round to the nearest tenth is needed
Answer:
250
Step-by-step explanation:
20% of 250 is 50. 100% of 250 is 250, therefore 20 percent of 250 equals 50.
More simplified explanation: The question is asking if 50 is 20% of a number, what is the number? So we know that 20% is 1/5 of 100%; if we know that 50 is 20% of something, then we would multiply 50 by 5 to get the answer. We would have to multiply 50 by 5 because if 50 is 20% of a number that would mean that 50 is 1/5 of the number we need to find, so to find the number, you to multiply 50 by 5.
