4 2/3 + 3 4/5 = 8 7/15

change to a common denominator:

4 10/15 + 3 12/15 = 7 22/15

reduce:

7 22/15 = 8 7/15

When the given mixed fractions are solved and tired to prove that both the sides are equal, the result will show that the given equation is correct.

A proper fraction that is less than one whole must represent the fractional portion of the mixed number. When a fraction is written properly, the top number, or numerator, must be less than the bottom number, or denominator.

A mixed fraction is one that has both a whole number and a fractional component. Additionally known as "Mixed numerals"

4 ⅔  + 3 ⅘  = 8  ⁷/ ₁₅  

¹⁴/ ₃ + ¹⁹ / ₅ = ¹²⁷ / ₁₅

⁷⁰ / ₁₅ + ⁵⁷ / ₁₅ = ¹²⁷ / ₁₅

¹²⁷ / ₁₅ =  ¹²⁷ / ₁₅

The result will demonstrate that the above equation is accurate when the given mixed fractions are solved and used to demonstrate that both sides are equal.

Lindsey and Justin must survey a random selection of two girls and two boys for each 7th grade class to get the most accurate results, so the correct choice is B.

This is so because, since precise information is required regarding a particular group of students (7th graders), it would be correct to target members of that group to obtain the first samples of information.

That is, by going to the most reliable source, a more reliable sample would be obtained.

Tax returns aren't gifts. They're refunds you get because the IRS withdrew too much from your paychecks or had withdrawals from other investment accounts. While it may seem like a great thing to have a tax return come each April, you pay for it the other 11 months of the year.

“A refund means you're giving your cash flow and income to the government in an interest-free loan.” The interest rate on one-year U.S. bonds is around 1.5%, so any interest the government could hypothetically pay on that loan would be very small: about $15 for every $1,000 in your refund.

Answer:

100 by 190 in.

Step-by-step explanation:

Ratios are only equal if both numbers are divided by the same number.

10 : 19 = (10 × 10) : (19 × 10)

10 : 19 = 100 : 190

You have not mentioned if there is more than one answer so lets check the rest:

10 : 19 = (10 × 10.7) : (19 × 10 and 3/19)

10 : 19 ≠ 107 : 193

10 : 19 = (10 × 10.7) : (19 × 10)

10 : 19 ≠ 107 : 190

10 : 19 = (10 × 10) : (19 × 10 and 3/19)

10 : 19 ≠ 100 : 193

Given:

The equation is:

[tex]3^x\times 9=3^{2n-1}[/tex]

To find:

The value of n in terms of x.

Solution:

We have,

[tex]3^x\times 9=3^{2n-1}[/tex]

It can be written as

[tex]3^x\times 3^2=3^{2n-1}[/tex]

[tex]3^{x+2}=3^{2n-1}[/tex]                [tex][\because a^ma^n=a^{m+n}][/tex]

On comparing the exponents, we get

[tex]x+2=2n-1[/tex]

Add 1 on both sides.

[tex]x+2+1=2n-1+1[/tex]

[tex]x+3=2n[/tex]

Divide both sides by 2.

[tex]\dfrac{x+3}{2}=n[/tex]

Therefore, the value of n is terms of x is [tex]n=\dfrac{x+3}{2}[/tex].

Answer:

45.7

Step-by-step explanation:

Hello there!

We can calculate the missing angle using trigonometry

here are the trigonometric ratios

sin = opposite over hypotenuse

cos = adjacent over hypotenuse

tan = opposite over adjacent

We are given x's opposite side length (8) and x's adjacent side length (7.8)

we are given the information to use the trigonometric ratio tangent

so now we create an equation (remember tan - opposite over tangent)

[tex]tan(x)=\frac{8}{7.8}[/tex]

now we solve for x

[tex]\frac{8}{7} =1.025641026[/tex]

we're left with

[tex]tan(x) =1.025641026[/tex]

finally we want to get rid of the tan

To do so we take the inverse of tan (arctan^-1) and apply it to each side

[tex]arctan^-^1tan(x)=x\\arctan^-^1(1.025641026)=45.7252243[/tex]

so x = 45.7252243

finally we round to the nearest tenth and get that the answer is

45.7

Answer:

Drone will take 0.25 hectare per minute to scan the area.

Step-by-step explanation:

By using unitary method,

A search and rescue drone takes 2 minutes to scan the area = 0.5 hectare.

Area scanned by the drone in 1 minute = [tex]\frac{\text{Total area scanned}}{\text{Total time taken}}[/tex]

                                                                 = [tex]\frac{0.5}{2}[/tex]

                                                                 = 0.25 hectare per minute

Therefore, drone will take 0.25 hectare per minute to scan the area.

_ = symbol after the two in the brackets that is high up and smaller.

Answer:

∠A = 116°

∠B = 116°

∠C = 64°

Step-by-step explanation:

since it is an isosceles trapezoid, ∠C = ∠D = 64°

∠A would be same side interior to ∠D so it would be 180° - 64° = 116°

∠B = ∠A = 116°

The  measure of each angle in the isosceles trapezoid are; ∠A = 116°

∠B = 116° and ∠C = 64°

Due to the figure being isosceles trapezoid, it is symmetric.

Isosceles trapezoid has its two rest sides(which aren't necessary parallel) are of equal length.

Since it is an isosceles trapezoid, ∠C = ∠D = 64°

Here we can use the  symmetric property of the isosceles trapezoid and the fact that a triangle has sum of its angles as 180°

We have ∠A that would be same side interior to ∠D

Thus, it would be 180° - 64° = 116°

∠B = ∠A = 116°
