Answer:
x = 350 gallons (amt of 60% solution that must be added)
Step-by-step explanation:
Amt of 60% solution = x gallons ; Amt of active ingredient = 0.6x gallons
Amt of 15% solution = 100 gallons ; Amt of active ingredient = 15 gallons
Amt of 50% solution = 100+x gallons ; Amt of active = 50 + 0.5x gallons
EQUATION:
Active ingredient: 0.60x + 15 = 50 + 0.50x
0.10x = 35
x = 350 gallons (amt of 60% solution that must be added)

Em uma perfumaria, um cliente pode montar um kit formado por um sabonete, um hidratante e um perfume. A loja possui 5 opções de sabonete, 8 de hidratante e 4 de perfume. Quantos kits diferentes um cliente poderá formar na perfumaria?
Answer:
The customer can form 160 different kits in the perfumery
Step-by-step explanation:
Here, we are interested in knowing the number of different kits a customer can form in the perfumery.
Now since each kit contains 1 each of moisturizers, soaps and perfume, what will happen is that we are going to select one each of the options
This means we shall be selecting 1 out of 5 soaps, 1 out of 8 moisturizer and 1 out of 4 perfumes
Mathematically, the number of ways we can select r items out of a total of n can be calculated as nCr
Applying this in the case we have;
It would be;
8C1 * 5C1 * 4C1
where
8C1 = 8, 5C1 = 5 and 4C1 = 4
Thus the number of options we have will be
= 8 * 5 * 4 = 40 * 4 = 160 kits
Responda:
O cliente pode formar 160 kits diferentes na perfumaria
Explicacao/etapas:
= 8 * 5 * 4 = 40 * 4 = 160 kits
espero que tenha ajudado! :) ......... tchau!

classify the following triangle check all that apply.
A. obtuse
B.Isosceles
C.Scalene
D.Acute
E.Right
F.Equilateral
Answer:
Scalene, Acute
Step-by-step explanation:
Scalene because each side has a different length
obtuse because one angle is more than 90°
If a triangle has sides of 8,11, and 13. Is it a right triangle?
If a² + b² = c², then the triangle is right.
So we have (8)² + (11)² ? (13)²
(8)² is 64, (11)² is 121, and (13)² is 169.
So we have 64 + 121 ? 169
64 + 121 is 185 and we can see that 185 > 169.
This triangle would not be a right triangle.
In fact, it would be an acute triangle.
So no, it's not a right triangle.

work out the area of the triangle to 1 decimal place. 10cm, 13cm, 105 degrees
Answer:
Area = 62.8 cm²
Step-by-step explanation:
In the figure attached a triangle has been given with two sides and included angle between them.
Measures of two sides are 10 cm and 13 cm.
Measure of included angle = 105°
Since area of a triangle with two sides (a and b) and included angle (θ) is,
[tex]\text{Area}=\frac{a.b.\text{sin}\theta}{2}[/tex]
= [tex]\frac{10\times13\times \text{sin(105)}}{2}[/tex]
= 62.79
≈ 62.8 cm²
Therefore area of the given triangle is 62.8 cm²

Issac runs 16 1/4 miles each week. He runs 6 3/8 miles on Sunday and 4 2/5 miles on Tuesday. How many miles does he run on Thursday if it is the only other day that he runs that week?
Answer:
5.225 miles on thursday or 209/40
Step-by-step explanation:
if we make it into decimals he runs 16.25 miles every week. on sunday he runs 6.375 miles and on tuesday it is 4.4. we are going to add what he’s run so far so
6.375 + 4.4 = 10.775 and then we will subtract that from 16.25 to get 5.225 left for thursday

Answer: b infinite number of solutions (blue and purple)
Step-by-step explanation:
There will be multiple solution for both inequality.
What is inequality?Inequality refers to the phenomenon of unequal and/or unjust distribution of resources and opportunities among members of a given society. The term inequality may mean different things to different people and in different contexts.
According to the question
y<3/2x-2 ---------- (1)
y<3/2x -8 -----------(2)
to take out points we have to take (1) as y= 3/2x-2
x y
-4 -8
-2 -5
0 -2
2 1
4 4
6 7
same for (2) we take y=3/2x -8
x y

6 1
Then we plot our graph which is shown in sheet attached
According to the graph we can see that they both are parallel to each other now we will shade left hand side of line as per the inequality
when we shade we will observe that points left side of equation (2) are common in both .

9. A rectangle is located on a coordinate plane. If the ordered pair (t, u) represents a vertex of this rectangle, which algebraic representation describes the effect of translating the rectangle 8 units up and 3 units left? (t, u) → (t + 3, u + 8) (t, u) → (t – 3, u + 8) (t, u) → (-t – 3, u + 8) (t, u) → (t + 8, u – 3)
Up is the y value and left is the x value.
In the point ( t,u) t is the x value and u is the y value.
Moving to the left, you subtract the value and moving up you add the value.
The answer would be (t, u) → (-t – 3, u + 8)

Yuron is sketching a scale drawing of a famous painting. The painting is 54 inches wide and 72 inches long. He used a scale factor of Two-thirds to make his sketch. How many inches wide is Yuron’s sketch?
Answer:
Yuron's painting is 36 inches wide.
Step-by-step explanation:
Given that Yuron is sketching a scale drawing of a famous painting which is 54 inches wide and 72 inches long. He used a scale factor of [tex]\frac{2}{3}[/tex] to make his sketch.
We are given to find the width of Yuron’s sketch.
Let, w and w' represents the width of the famous painting and Yuron's painting.
Then, w = 54 inches, w' = ?
We know that the scale factor is defined by
[tex]S=\frac{Length of a side of a dilated figure}{Length of the corresponding side of the original figure}[/tex]
Therefore, we have
[tex]\frac{2}{3} =\frac{Width og Yuron's painting}{Width of the famous painting}[/tex]
[tex]\frac{2}{3} = \frac{w}{w}[/tex]
[tex]\frac{2}{3}=\frac{w}{54}[/tex]
[tex]\frac{2}{3}=\frac{2*54}{3}[/tex]
[tex]w= 36[/tex]
Thus, Yuron's painting is 36 inches wide.
Answer:
Yuron's painting is 36 inches wide.

the shape of a toy cylinder has a radius of 5cm and height of 8cm on top a hemisphere of radius 5cm , calculate the volume of the toy
someone should pls help me
Answer:
890.1 cm^3
Step-by-step explanation:
The volume of the cylinder is given by the formula ...
V = πr^2h
Filling in the given numbers, we find the volume of the cylinder to be ...
V = π(5 cm)^2(8 cm) = 200π cm^3
__
The volume of a hemisphere is given by the formula ...
V = (2/3)πr^3
Filling in the given radius, we find the hemisphere volume to be ...
V = (2/3)π(5 cm)^3 = 250π/3 cm^3
__
The total volume of the toy is presumed to be the sum of these volumes, so is ...
toy volume = (200π cm^3 +250π/3 cm^3) = 850π/3 cm^3
toy volume ≈ 890.1 cm^3

Ukrainian: 1/20
Vietnamese:0.02
French: 1/10
Chinese:0.02
other: 0.06
Answer:
English,French,Vietnamese,Chinese,Ukrainian,other
Step-by-step explanation:
so basically the question is asking for us to convert the fractions into decimals and then, order the them from greatest to least
Q:how do you convert a fraction into a decimal?
A: numerator divided by denominator for example if you had to convert 7/9 into a decimal you would do 7 divided by 9!!!
English:1/4 is equivalent to 0.25
Ukrainian:1/20 is equivalent to 0.05
Vietnamese:0.02 is already in decimal form
French:1/10 is equivalent to 0.1
Chinese:0.02 is already in decimal form
Other:0.06 is already in decimal form
Now we got all the fractions converted into decimals
0.25,0.05,0.02,0.1,0.02,0.06
Now we have to put these number from greatest to least
Q:how do we put it in greatest to least?
A: if there are more zeros in the place value its more likely to be a small number for example 0.06 is smaller than 0.3
0.25 is the greatest
0.1 is the second greatest
0.02 is the third greatest
0.02 is the third greatest
0.05 is the 4th greatest
0.06 is the 5th greatest
Now we got them from greatest to least so we match the decimal numbers to the language
Starting from greatest to least is: English,French,Vietnamese,Chinese,Ukrainian,other

A cylinder-shaped water tank is 160 cm tall and measures 87.92 cm around.
What is the volume of the water tank?
Enter your answer as a decimal in the box. Use 3.14 for π.
Answer:
Step-by-step explanation:
The volume formula for a cylinder is
[tex]V=\pi r^2h[/tex]
In order to find the radius we need to use the circumference we were given. The formula for the circumference is
[tex]C=2\pi r[/tex]
Filling in the info about the circumference value of 87.92:
[tex]87.92=2(3.14)r[/tex] or
87.92 = 6.28r so
r = 14
Now that we know the radius we can fill in the volume formula:
[tex]V=(3.14)(14)^2(160)[/tex] and
V = 98470.4 cm cubed

what will be the another acute angle of right angle triangle is its one acute angle is 30 degree
Answer:
60°
Step-by-step explanation:
90+30=120°
180-120=60°
Step-by-step explanation:
all sides of a triangle = 180
all sides of a triangle = 180
So 2 angle i.e. 90° (right angle) and 30° (given) and let third angle be x
so equation forms like
180 = 90+30+x
180 =120+x
180-120 =x
60 =x
SO THE ANSWER WILL BE 60°
