A baseball coach order hats for his team. Each hat cost $10. The shipping charger is $6. The total cost of the order must be less than $125. Which inequality can be used to solve?
Answer:
10x + 6 < 125
Step-by-step explanation:
Hi,
10x is the cost per hat. 6 is the charging fee. 125 is the total cost of the order. We put x because we don't know how many hats they're going to buy. 6 is the amount they pay no matter what. And < is used because the total cost has to be less than 125, not less than or equal to, but LESS than.
Hope this helps

The product of 45 and the counting number n is a perfect cube. find the least possible value for n.
PLS HELP.
The counting number n is 75 which when multiplied with 45 gives perfect cube.
What is a perfect cube?Numbers which are the triple product of the exact number are known as perfect cubes.
In other words, we can say the value produced by multiplying a whole number by three times itself is a perfect cube.
A number that may be expressed as three times the product of another integer is also termed as a perfect cube.
It is given in the question that the product of 45 and the counting number n is a perfect cube
So, we have to find the counting number n
First of all we will factorise 45
45 = 5 × 9
After factorising we get,
45 = 3×3×5
For 45 to become perfect cube we have to multiply the factors with 3×5²
45 = 3×3×3×5×5×5
∴ 3×5² = 75
Hence , the counting number n is 75 which when multiplied with 45 gives perfect cube.

An octagon has an area of 55.3 square inches. It is a smaller version of an octagon whose dimensions are 7 times larger. What is the area of the larger octagon?
9514 1404 393
Answer:
2709.7 square inches
Step-by-step explanation:
If the linear dimensions are a factor of 7 larger, then the area is a factor of 7^2 = 49 larger.
larger area = 49(55.3 in^2) = 2709.7 in^2

Triangle PQR is transformed to triangle P′Q′R′. Triangle PQR has vertices P(8, 0), Q(6, 2), and R(−2, −4). Triangle P′Q′R′ has vertices P′(4, 0), Q′(3, 1), and R′(−1, −2).
Plot triangles PQR and P′Q′R′ on your own coordinate grid.
Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P′Q′R′? Explain your answer. (4 points)
Part B: Write the coordinates of triangle P′′Q′′R′′ obtained after P′Q′R′ is reflected about the y-axis. (4 points)
Part C: Are the two triangles PQR and P′'Q′'R′' congruent? Explain your answer. (2 points)
Answer:
The scale factor from triangle PQR to P'Q'R' is 1/4.
The length of each side of the triangle is divided by 4, in other words it is multiplied by the scale factor of 4.
If P'Q'R" is reflected over the y-axis the new points would be: (1, 0) (0, 1) and (-2, 1).
No, the triangles are not congruent. There was a dilation of 1/4 in the triangles.

Which is the better deal: $4.47 for 3 liters or $7.25 for 5 liters? Explain why.
Answer:
$7.25 for 5 liters
Step-by-step explanation:
If you get the unit rate of $4.47 for 3 liters it is 1.49 per liter.
1.49 x 5 = 7.45
Therefore, $7.25 for 5 liters is a better deal than $7.45 for 5 liters.
