  • <em>Answer:</em>

<em>60 ; 100</em>

  • <em>Step-by-step explanation:</em>

<em>Hi there ! </em>

<em>HCF = 20 = 4×5 = 2²×5</em>

<em>LCM = 300 = 3×100 = 3×4×25 = 2²×3×5²</em>

<em>LCM/HCF = 2²×3×5²/2²×5 = 3×5</em>

<em>a = 3×hcf = 3×20 = 60</em>

<em>b = 5×lcm = 5×20 = 100</em>

<em>Good luck !</em>

Answer:

<h2>b = 8</h2>

Step-by-step explanation:

\text{Use}\ \log_ab=c\iff a^c=b,\ \text{for}\ a>0,\ b>0\ \wedge\ a\neq1\\\\Domain:b>0\ \wedge\ b\neq1\\\\\log_b(512)=3\iff b^3=512\to b=\sqrt[3]{512}\\\\\begin{array}{c|c}512&2\\256&2\\128&2\\64&2\\32&2\\16&2\\8&2\\4&2\\2&2\\1\end{array}\\\\512=2^9=2^{3\cdot3}=(2^3)^3=8^3\\\\\text{Therefore}\ b=\sqrt[3]{512}=\sqrt[3]{8^3}=8\in D

\text{Used:}\\\\(a^n)^m=a^{nm}\\\\\sqrt[n]{a^n}=a

John needs to make a scale drawing of his school building for art class. If the building is 256.25 meters long, and John scales
grin007 [14]
The Answer Is 10.25 inches. Since the building is 256.25 meters and 25 meters equals 1 inch, then you would divide 256.25 by 25.
256.25/25= 10.25 inches. I hope this helps!

A small company manufactures picnic tables. The daily fixed cost is 1,200 and the variable cost is $45 per table. How many picni
nekit [7.7K]

Using a linear function, it is found that 80 picnic tables can be produced for a total daily cost of 4,800.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

Considering the daily fixed cost of 1200 as the y-intercept, and the variable cost of 45 as the slope, the linear function for the cost of producing n picnic tables is given by:

C(n) = 1200 + 45n.

Now, we have to solve for n when C(n) = 4800, hence:

1200 + 45n = 4800

45n = 3600

n = 3600/45

n = 80.

What is a1 of the arithmetic sequence for which a3=10 and a51=−182?
Furkat [3]

Answer:

a₁ = 18

Step-by-step explanation:

The n th term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₃ = 10 and a₅₁ = - 182, then

a₁ + 2d = 10 → (1)

a₁ + 50d = - 182 → (2)

Subtract (1) from (2) term by term to eliminate a₁

48d = - 192 ( divide both sides by 48 )

d = - 4

Substitute d = - 4 into (1) and evaluate for a₁

a₁ + 2(- 4) = 10

a₁ - 8 = 10 ( add 8 to both sides )

a₁ = 18
