Bright Blocks toy company sells sets of building blocks. The Beginner Builder set has 40 large blocks and 25 small blocks. The Mega Maker set has the same ratio of large blocks to small blocks, but it comes with 100 small blocks.
How many large blocks are in the Mega Maker set? HELPPPPPPPP
The required number of large blocks in the Mega maker set is 160.
What is the Ratio?The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
here,
The Beginner Builder set has 40 large blocks and 25 small blocks.
Ratio of large to small blocks = 40 / 25 = 8/5
The Mega Maker set has the same ratio of large blocks to small blocks, but it comes with 100 small blocks.
Let the number of large blocks in the Mega maker set be x,
The ratio of large to small blocks = x / 100
Comparing the ratios,
8 / 5 = x / 100
x = 160
Thus, the required number of large blocks in the Mega maker set is 160.

Type your answer in the box.You may use numbers.Symbols.And /or text in your answer. Simplify the expression completely.Leave your answer in radical form. 60 ÷ 5
Answer:
60÷5 = 12
Step-by-step explanation:
Given the expression 60 ÷ 5, we ate yo simplify it in its simplest form.
Write the factors of 60 first
60 = 5 × 12
60÷5 = (5×12)÷5
60÷5 = (5×12)/5
60÷5 = 5/5 × 12
60÷5 = 1×12
60÷5 = 12
Hence the answer to the given expression is 12.

Anna has $430. She wants to buy a phone that costs $275. Anna will also have to pay a sales tax of 7%.
How much tax will Anna pay?
What the total price including sales tax?
How much money will Anna have left after her purchase?
Answer:
TOTAL TAX IS: $19.25
TOTAL PRICE IS: $294.25
MONEY LEFT IS: $135.75
Step-by-step explanation:
First, you do a proportion:
?/275 = 7/100
the ?/275 represents how much money in $275
the 7/100 represents 7% (7 hundredths)
then you cross multiply:
275 x 7 = 1925
then you divide:
1925 divided by 100 = 19.25
So $19.25 is the tax amount.
To get the total price, you add:
Tax ($19.25) + Cost($275) = $294.25
$294.25 is the total amount that Anna has to pay.
To get what Anna has left over, you subtract:
Has($430) - Spend($294.25) = $135.75
Anna has $135.75 left.

Consider a function f(x) such that f(5x) =x-5/5x-1. Find f(x) and hence write down the domain of f(x).
9514 1404 393
Answer:
f(x) = (x -25)/(5x -5)x ≠ 1Step-by-step explanation:
To find f(x), you can replace x in the given function with (x/5).
f(5(x/5)) = (x/5 -5)/(5(x/5) -1)
f(x) = (x/5 -5)/(x -1)
f(x) = (x -25)/(5(x -1))
f(x) = (x -25)/(5x -5)
The only domain restriction is that x cannot make the denominator zero:
x cannot be 1. (The domain is all real numbers except 1.)

A scientist used 786 milliliters of a liquid for an experiment. How many liters of the liquid did the scientist use for this experiment?
Answer:
0.786 liters
Step-by-step explanation:
786/1000 = 0.786
Answer:
the answer is 0.786 liters
Step-by-step explanation:
because 1 milileter is 0.001 liter, when you multiply 786 and 0.001 you get 0.786. Your welcome (pls give brainliest)
Solve 3x2+48x−12=0 by completing the square.
Answer:
Step-by-step explanation:
3x²+48x-12=0
divide everithing by 3
x²+16x-4 =0
(a+b)² = a²+ 2ab+ b²
so a=1, 2ab=2*1*b=2b=16 =2*8 therefore b=8
(x+8)²-4 -64 = 0 (make sure you take away the b²=64)
(x+8)² = 68
√(x+8)² = √68
x+8 = ±2√17
x= -8±2√17

1. A water wheel rung’s height as a function of time can be modeled by the equation:
h - 8 = -9 sin6t
(b) Determine the maximum height above the water for a rung.
Answer:
-1
Step-by-step explanation:
1. A water wheel rung’s height as a function of time can be modeled by the equation:
h - 8 = -9 sin6t
(b) Determine the maximum height above the water for a rung.
Given the rung's height modeled by the equation;
h - 8 = -9 sin6t
h(t) = -9sin6t + 8
At maximum height, the velocity of the rung is zero;
dh/dt = 0
dh/dt = -54cos6t
-54cos6t = 0
cos6t = 0/-54
cos6t = 0
6t = cos^-1(0)
6t = 90
t = 90/6
t= 15
Substitute t = 15 into the expression to get the maximum height;
Recall:
h(t) = -9sin6t + 8
h(15) = -9sin6(15) + 8
h(15) = -9sin90 + 8
h(15) = -9(1)+8
h(15) = -9+8
h(15) = -1
hence the maximum height above the water is -1

Simply both sides of the equation
8x−3(2x−4)=3(x−6)
8x+(−3)(2x)+(−3)(−4)=(3)(x)+(3)(−6)(Distribute)
8x+−6x+12=3x+−18
(8x+−6x)+(12)=3x−18(Combine Like Terms)
2x+12=3x−18
2x+12=3x−18
Step 2: Subtract 3x from both sides.
2x+12−3x=3x−18−3x
−x+12=−18
Step 3: Subtract 12 from both sides.
−x+12−12=−18−12
−x=−30
Step 4: Divide both sides by -1.
[tex]\frac{-x}{-1} =\frac{-30}{-1}[/tex]
x=30
