STRUCTURE Write the ratio of the side lengths of the two cubes described in simplest form.
The volumes of the two cubes are 270x cubic inches and 32x2 cubic inches.
The surface areas of the two cubes are 6x4 square feet and 6(x + 1) square feet.
Simplify (2x-3)(2x-2)
Answer:
We get the final answer of -4x + 6
Step-by-step explanation:
Let's simplify step-by-step.
2x −3(2x−2)
Distribute:
= 2x+ (−3)(2x) + (−3)(−2)
= 2x+ −6x + 6
Combine Like Terms:
= 2x + −6x + 6
= (2x + −6x) + (6)
= -4x + 6
Sofia surveyed students at her school
about the language they speak at home.
She got these results. Write decimal
equivalents for the fractions and order
the numbers from greatest to least.
english:1/4
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

find an equation of cosine function with maximum of 7, minimum of -7 and period of 7
Answer: [tex]\bold{y=7cos\bigg(\dfrac{2\pi}{7}x\bigg)}[/tex]
Step-by-step explanation:
y = A cos (Bx - C) + D
A = amplitude (vertical stretch)Period = 2π/BC/B = phase shiftD = vertical shiftThe minimum is -7 and the max is 7 so A = 7 and D = 0
Period is 7. Since P = 2π/B then 7 = 2π/B --> B = 2π/7
Nothing was stated about a phase shift so you can use any value for C. I chose C = 0.
Now, input A = 7, B = 2π/7, C = 0, & D = 0 into the equation
[tex]y=7\cos\bigg(\dfrac{2\pi}{7}x-0\bigg)+0\\\\\\\text{Simplify}:\\y=7\cos\bigg(\dfrac{2\pi}{7}x\bigg)[/tex]

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)

Step-by-step explanation:
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.

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!

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

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°

Multiply first two values in brackets:
5 x 4 = 20
Multiply the outside values in the brackets:
-x * 5 = -5x
Multiply the inside terms:
-x * 4 = -4x
Multiply the last terms:
-x * -x = x^2
Place all values together:
x^2 - 5x - 4x + 20
Simplify it:
x^2 -9x + 20

Is the number even or odd?
2018−2017+2016−2015 + . . . +2–1
Answer:
It is the odd number 1009
Step-by-step explanation:
Notice that this problem involves the addition of a number "1" per consecutive pair (a number minus the integer that immediately precedes it), so it adds "1" (one) every couple of consecutive numbers.
2018 - 2017 = 1
2016 - 2015 = 1
...
4- 3 = 1
2 - 1 = 1
That means it is the addition of 2018/2 = 1009 numbers "1". This clearly results on the number 1009, which is an odd number.

Which of the following exponential regression equation best fits the data shown below. Please help ASAP. ☺️
Answer:
Option D [[tex]y=6.61\,*\,1.55^x[/tex]] in the list of possible answers
Step-by-step explanation:
For this problem you are supposed to use a calculator that allows you to do an exponential regression. There are many tools that can help you with that, depending on what your instructors has assigned for your class.
I am showing you the results of a graphing tool I use, and which after entering the x-values and the y-values in independent "List" forms, when I request the exponential regression to fit the data, I get what you can see in the attached image.
Notice that the exponential of best fit with my calculator comes in the form:
[tex]y=A\,e^{k\, x}[/tex]
with optimized parameters:
[tex]A \approx 6.6114\,\,\,and\,\,\, k=0.4378321[/tex]
Notice as well that since:
[tex]e^{0.4378321} \approx 1.5490[/tex]
the exponential best fit can also be written:
[tex]y=6.611403\,\,*\,e^{0.4378321\, x}=6.611403\,*\,1.549^{\,x}[/tex]
and this expression is very close to the last option shown in your list of possible answers

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
