Answer:75/6
Step-by-step explanation: Y is proportional to x so 12 is proportional to 5 so if y=30 then it will be 30*5/12=150/12=75/6
1. Write the following in exponential form and as a multiplication sentence using only 10 as a factor
(e.g., 100 = 102= 10 x 10).
a. 1,000
b. 100 x 100
2. Write the following in standard form (e.g., 4 x 102 = 400).
a. 3 x 102=
C.
800 - 103 =
I
b. 2.16 x 104 =
d. 754.2 - 102 =
Answer:
1. a. 1,000 = 10³ = 10 × 10 × 10
b. 100 × 100 = 10² × 10² = 10 × 10 × 10 × 10
2. a. 3 × 10² = 300
b. 2.16 × 10⁴ = 21,600
c. 800 ÷ 10³ = 0.8
d. 754.2 ÷ 10² = 7.542
Step-by-step explanation:
3. a. 1,000
There are 3 zeros in 1000. This is equivalent to 10 raised to the power of 3. Writing this in multiplication sentence using 19 as the only factor, we would have:
1,000 = 10³ = 10 × 10 × 10
b. 100 × 100
Using the same logic as explained in (a) above, we would have:
100 × 100 = 10² × 10² = 10 × 10 × 10 × 10
2. a. 3 × 10²
Convert 10² to 100 and multiply both numbers
3 × 10² = 3 × 10 × 10 = 3 × 100 = 300
b. 2.16 × 10⁴
2.16 × 10 × 10 × 10 × 10 = 2.16 × 10,000
Multiplying both numbers, since we have 4 zeros, move the decimal point 4 places to the right.
2.16 × 10,000 = 21,600
c. 800 ÷ 10³ = 800 ÷ 10 × 10 × 10
800 ÷ 1,000
There are 3 zeros in 1000, since we are dividing, move the decimal point 3 places to the left.
800 ÷ 1,000 = 0.8
d. 754.2 ÷ 10² = 754.2 ÷ 10 × 10
754.2 ÷ 100
Move the decimal point 2 places to the left.
754.2 ÷ 100 = 7.542

Solve For H ---I> A=1/2(B₁+B₂)h
Answer:
h = 2A/(B₁+B₂)Step-by-step explanation:
Given equation
A=1/2(B₁+B₂)hSolving for h
A=1/2(B₁+B₂)h2A = (B₁+B₂)h2A/(B₁+B₂)= hh = 2A/(B₁+B₂)The population of fish in an aquarium can be modeled after exponential growth. If there were originally 3 fish and after 6 weeks there were 31 fish, how many fish would there be after 14 weeks?
Answer:
The population in 14 weeks is 232 fishes
Step-by-step explanation:
The equation for exponential growth is f(x) = a·(1 + r)ˣ
Where;
a = The starting population size = 3
r = The rate at which the population of grows
x = The number of periods to of change of the population
Therefore, we have;
f(6) = 31 = 3 × (1 + r)⁶
31/3 = (1 + r)⁶
㏑(31/3) = 6㏑(1 + r)
(㏑(31/3))/6 =㏑(1 + r)
1 + r = e^((㏑(31/3))/6) ≈ 1.476
1 + r ≈ 1.476
Therefore, the population in 14 weeks is given as follows;
f(14) = 3 × (1.467)¹⁴ ≈ 232.574
Given that we the information is with regard of living things, such that there are no fractions, we round down to the nearest whole number as follows;
f(14) ≈ 232
The population in 14 weeks = 232 fishes.

How are the areas of the smaller squares related to the area of the biggest square? Do you notice something?
If a = the side of one small square and b = the side of the other small square and c = the side of the biggest square, then how could you write an equation using a, b, and c with exponents?
This is the Pythagorean Theorem for all Right Triangles. ____________________
Answer:
The sum of area of two smaller squares is equal to the area of bigger square
An equation using a, b, and c with exponents is [tex]c^2=a^2+b^2[/tex]
Step-by-step explanation:
Let a be the side of the smallest square , b be the side of other smaller square and c be the side of biggest square
Area of square with side a = [tex]Side^2 = a^2[/tex]
Area of square with side b = [tex]Side^2 = b^2[/tex]
Area of square with side c =[tex]Side^2 = c^2[/tex]
Refer the attached figure
In triangle ABC
[tex]\angle A = 90^{\circ}[/tex]
So, We can use Pythagoras theorem over here
AB = a = Base
AC = b = Perpendicular
BC = c = Hypotenuse
[tex]Hypotenuse^2=Perpendicular^2+Base^2\\c^2=a^2+b^2[/tex]
So, The sum of area of two smaller squares is equal to the area of bigger square
An equation using a, b, and c with exponents is [tex]c^2=a^2+b^2[/tex]
A boutique owner sells a salt scrub that is made of a tropical oil blend costing $7.95 per ounce and sea salt costing $1.45 per ounce. The salt scrub ultimately costs $3.40 per ounce. In order to make a new batch of the salt scrub, she just ordered 6 ounces of the tropical oil blend. How many ounces of sea salt will she need to make the salt scrub with the correct proportions?
Answer:
14
Step-by-step explanation:
7.95\cdot 6+1.45\cdot \:x=\left(6+x\right)3.4

Write an equation in slope-intercept form for the line that passes through (3, 7) and is parallel to the line with equation y=3/4x-5
Answer:
[tex]y=\frac{3x}{4} +\frac{19}{4}[/tex]
Step-by-step explanation:
Plug-in given to the point-slope form:
m = 3/4
(the slope is the same for the other line as the two are parallel to each other)
(3 , 7)
[tex]y - 7 = \frac{3}{4} (x - 3)\\ y-7 = \frac{3}{4} x - \frac{9}{4} \\4( y-7) =( \frac{3}{4} x - \frac{9}{4})4\\ 4y - 28 = 3x - 9\\ 4y - 28 +28 = 3x - 9 + 28\\4y = 3x + 19\\\frac{4y}{4} =\frac{3x+19}{4} \\y=\frac{3}{4}x +\frac{19}{4}[/tex]

The area of AXYZ is žyh
by the definition of the area of a triangle. Using the sine ratio, sin(x) = . Also, asin(x) = h is true by the
multiplication property of equality. So, by the substitution property of equality, the area of AXYZ is 2xysin(x).
Where did Jayden make his first error in the proof?
The first error Jayden made in teh proof is: D. the sine ratio, sin(X) = h/x is incorrect, its should be sin(Z) = h/x.
What is the Sine Ratio?Whn solving a right triangle, the sine ratio can be used which is expressed as, sin ∅ = opposite side/hypotenuse, given that ∅ is the refrence angle.
In the proof of Jayden, the area of the triangle is correct, which is 1/2(base × height).
However, the sine ratio is wrong.
Therefore, the first error Jayden made in teh proof is: D. the sine ratio, sin(X) = h/x is incorrect, its should be sin(Z) = h/x.

Answer as a fraction in simplest form.
Louie drove 50 1/8 miles and used 2.5 gallons of gas. Find the number of miles driven per gallon of gas.
Hey there!
=> 50 1/8 {improper fraction}
=> 401/8 {proper fraction}
=> 401/8 ÷ 2.5
=> 50.125 ÷ 2.5 { Divide}
=> 20.05
Convert [tex]20.05[/tex] to fraction
Rewrite the decimal number as a fraction with 1 in the denominator
20.05=20.05/1
Multiply to remove 2 decimal places. Here, you multiply top and bottom by 102 = 100
20.05/1×100/=2005/100
Find the Greatest Common Factor (GCF) of 2005 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 5,
2005÷5/100÷5=40/120
Simplify the improper fraction,
=20 1/20
Or, 401/20

im givin away myy last of points here is my question anyone can answer dis even people who just want points: Charise is buying 6 packets of seeds to plant in her garden. Each packet of seeds is $2.19. Estimate her total cost by rounding. Is the estimate an underestimate or an overestimate?
$12; underestimate
$18; underestimate
$12; overestimate
$18; overestimate
Answer:
It would be $12 overestimate
Step-by-step explanation:
$2.19 rounded to one significant figure would be $2.00
$2.00 multiplied by 6 would be $12
However since 19 cents is over $2, this means it's a definite overestimate
