Answer:169.92 cm^2
Step-by-step explanation:
The base is 7.2 x 7.2 (This equals 51.84)
The area of one triangle is 29.52
There are 4 triangles with the same side lengths so you multiply 29.52 x 4.
This would equal 188.08.
Then you add everything together.
This equals 169.92 cm^2.
Answer:1,000 m^3
The formula for volume is hlw.
One of the side lengths of the cube is 10.
If the height, length, and width are ten, then you multiply them all together.
This would give you 1,000.

The mixed fraction approximation for the given terms using the perfect squares method are:
2√(4)√(5/4)3√(1)√(2/1)2√(1)√(3/1)How do we approximate the square roots using the perfect squares?To approximate the square roots using the perfect squares method, we need to find the largest perfect square that is less than each of the given terms, and then simplify.
For 2√5:
The largest perfect square less than 5 is 4, so we can write 2√5 as 2√(4)√(5/4).
Simplifying, we get:
2√(4)√(5/4)
= 2(2)√(5/4)
= 4√(5/4)
= 4√5/√4
= 4√5/2
= 2√5.
For 3√2:
The largest perfect square less than 2 is 1, so we can write 3√2 as 3√(1)√(2/1).
Simplifying, we get:
3√(1)√(2/1)
= 3(1)√(2/1)
= 3√2/√1
= 3√2.
For 2√3:
The largest perfect square less than 3 is 1, so we can write 2√3 as 2√(1)√(3/1).
Simplifying, we get:
2√(1)√(3/1)
= 2(1)√(3/1)
= 2√3/√1
= 2√3.

Answers
Answer:
790,000
Step-by-step explanation:
The 5 represents the number by itself so it would be
10x10x10x10x10=100,000
7.9x100,000=790,000
Step-by-step explanation:
if you multiply something by 10 = 10¹, you move the decimal point 1 position to the right (and fill up with a 0, if necessary).
if you multiply something by 100 = 10², you move the decimal point 2 positions to the right (and fill up with 0s as needed).
if you multiply something by 1000 = 10³, you move the decimal point 3 positions to the right (and fill up with 0s as needed).
...
you see the pattern ?
so, when multiplying by 10⁵ (100,000) we shift the decimal point 5 pairings to the right and fill up with 0s as needed.
therefore,
7.9 × 10⁵ = 790,000.-
How do you do these? There is more than one question so I need help answering all.
Answers
-(x-5)=0
Your A value (-1) multiplies by everything inside of the parentheses.
-x+5=0
You move your constant (5) to the right side of the equation and flip the sign from a positive 5 to a negative 5.
-x=5 (5 + 0 just equals 5)
To get rid of the negative sign on the X, divide both sides of the equation by -x.
The answer would be:
x=5
You can repeat this process for other similar equations.
To turn equations into distributive form, follow these steps:
I see you gave me an equation with 5x + 11x. Remember, we are trying to get an A value and parenthesis. To do this, we need to find the GCF (Greatest common factor). Ex: If you were putting 5+10 in distributive form, the GCF would be 5, because five is the greatest common factor between 5 and 10, meaning it's the greatest possible number that goes into 5 (1 time) and 10 (2 times).
Although, there is no GCF in 5x+11x, but there are two common X values, so this may be put into distributive property such as:
X(5+11)
And if there's one variable like 9n+36, than it would be shaped like:
9(n+4)
For word problem 12 you have provided, they give you the base amount of cost when you purchase the ad is (84$) and the cost every day to run it is (28$). The max amount of money we can spend is 700$. With an initial cost of 84$, we can deduct 84$ from the max of 700$, which would leave us with 616$. We can than divide 616$ by 28$ to see how many days we can keep the ad running, which equals 22. So the max amount of days that the ad can be up is 22 days.
For 13, 1 basket is 12 inches tall, and 13.5 inches tall when another one is stacked inside of it. All we have to do here is subtract 12 from 13.5, which gives us 1.5. That means that every basket stacked adds another 1.5 inches. So if you stacked 5 baskets inside of one, it would be 1.5 x 5 + 12.
In 7 for the unit rates, it's just saying that 0.8 of a centimeter grew in four sevenths of a week. It wants to know how many centimeters a week, which would be around 1.4 centimeter per week because 4/5 divided by 4/7 = 7/4 which equals 1.4.
Where you rewrite the expressions to find the least amount of terms, literally all you are doing is combining like terms. on 10 D, you would first distribute 5 and than solve for any like terms (also the parentheses between both equations don't matter because of the sign in between them so you can just remove them). It should be self explanatory to combine like terms so on (like terms includes constants).

Triangle ABC with vertices at A(4, 3), B(3, −2), C(−3, 1) is dilated using a scale factor of 1.5 to create triangle A′B′C′. Determine the vertex of point A′.
A: A′(−6, 4.5)
B: A′(4, 4.5)
C: A′(6, 3)
D: A′(6, 4.5)
Answers
A' = k * A + (1 - k) * O
where k is the scale factor, A is the original coordinates of vertex A, and O is the center of dilation. Since no center of dilation is given, we can assume that the origin (0, 0) is the center of dilation.
So, using k = 1.5, A = (4, 3), and O = (0, 0), we get:
A' = 1.5 * (4, 3) + (1 - 1.5) * (0, 0)
= (6, 4.5) + (0, 0)
= (6, 4.5)
Therefore, the coordinates of vertex A' after the dilation are (6, 4.5).
Thus, the correct answer is option D: A′(6, 4.5).

John puts $70 in a savings account that earns 6% annually. The interest is not compounded. How many years will it take John to make at least $100 in interest?
Answers
Answer:
24 years
Step-by-step explanation:
If interest is not compounded, it is called simple interest.
Simple interest is calculated as a percentage of the principal amount and is applied only to the principal.
The formula for simple interest is:
[tex]\boxed{\sf I = Prt}[/tex]
where:
I = Total interest earned.P = Principal amount.r = Interest rate (in decimal form).t = Time (in years).The given values are:
I = $100P = $70r = 6% = 0.06Substitute the given values into the formula and solve for t:
[tex]\implies \sf 100=70 \cdot 0.06 \cdot t[/tex]
[tex]\implies \sf 100=4.2 t[/tex]
[tex]\implies \sf 4.2 t=100[/tex]
[tex]\implies \sf \dfrac{4.2 t}{4.2}=\dfrac{100}{4.2}[/tex]
[tex]\implies \sf t=23.8095238...\;years[/tex]
We need to round up to the next year. Therefore, it will take 24 years for John to make at least $100 in interest.
Answer:
approx. 24 years
Step-by-step explanation:
The formula to find the simple interest is:
[tex]\sf I= \frac{prt}{100}[/tex]
Here,
I ⇒ Interest ⇒ $ 100
p ⇒ principle ⇒ $ 70
r ⇒ rate ⇒ 6
t ⇒ time ( years )
Let us find the time taken using the formula.
[tex]\sf I= \frac{prt}{100}\\\\100=\frac{70*6*t}{100} \\\\100*100=420t\\\\10000=420t\\\\23.8\: years=t\\\\approx. \:24 \:years=t[/tex]

Jaden made a rectangular sign that is 1.4 meters long and 1.2 meters wide to post on the wall of his store. How many square meters of wall does the sign cover? The answer is 1.68, but to solve the problem, you need to find 1.4 x 1.2(which it is 1.68). Estimate the area of wall that the sign will cover. Explain your thinking please.
Answers
First, we can round the dimensions of the sign to the nearest whole number to make the multiplication easier. Rounding 1.4 to 1 and 1.2 to 1, we can estimate that the sign covers approximately 1 square meter of wall.
This estimation assumes that the sign is placed directly on the wall with no gaps or overlaps. In reality, the actual area of wall covered by the sign may be slightly larger or smaller depending on the installation method and any spacing between the sign and the wall.
It's important to note that while estimation can be useful for getting a rough idea of the answer, it's not always accurate and should not be relied upon for precise calculations. In this case, using the actual dimensions of the sign to find the area of the wall covered (1.4 x 1.2 = 1.68 square meters) gives a more accurate result.
