Answer:

Step-by-step explanation:Situation A: The hang glider descended 33.57 feet and again ascended 14.98. So 33.57 - 14.98 = 18.58. So now the hang glider is at 18.58 feet

Situation B: Initially they gained 7 2/5 yards and then lost 3/5 yards.

7 2/5 yards can be written as 37/5. As they lost 3/5 yards, 37/5 - 3/5 = 34/5. So the remaining yards are 34/5 yards.

Situation C: Hiker walked 3 1/6 miles and then 2 1/2 miles. So the total distance is 3 1/6 + 2 1/2 = 5 4/6 miles.

Situation D: Total amount earned is $23.66 + $15.84 = $39.5.

Answer:

(-1, 8)

Step-by-step explanation:

Make y the subject:

x + y = 7 ⟹ y = -x + 7

1. Substitute the value for y into 7x + y = 1 and solve for x:

7x + (-x + 7) = 1

7x - x + 7 = 1

6x + 7 = 1

6x + 7 - 7 = 1 - 7

6x = -6

6x ÷ 6 = -6 ÷ 6

x = -1

2. Substitute the given value of x into x + y = 7 and solve for y:

x + y = 7

-1 + y = 7

-1 + 1 + y = 7 + 1

y = 8

Therefore, the solution to this system of equations is: (-1, 8).

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143

Answer:

\(\boxed{\sf 6 u + \dfrac{10}{3}}\)

Explanation:

Given expression:

\(\sf \rightarrow \dfrac{2}{3} (5+9u)\)

distribute inside parenthesis

\(\sf \rightarrow \dfrac{2}{3} (5)+ \dfrac{2}{3} (9u)\)

multiply variables

\(\sf \rightarrow \dfrac{10}{3} + \dfrac{18}{3} u\)

simplify following

\(\sf \rightarrow 6 u + \dfrac{10}{3}\)

Answer:

This looks pretty easy. Is this a trick question or what? I might be wrong but the answer seems to be B. 110 lb.

Step-by-step explanation:

Solution:

Given,

weight of Randy = 50 pounds

weight of his father = 160 pounds

difference in their weights = ?

Now,

difference in their weights =

weight of his father - weight of Randy

= 160 - 50

= 110 pounds

Therefore, the difference in their weights is 110 pounds.

Answer:

\(A=\frac{ab}{2}\) or \(A = a *\sqrt{c^2-a^2} /2\)

Step-by-step explanation:

Depending on the values you take depends on the equation you would use to solve for the area of a right triangle(the first answer accounts for measuring both arms(the sides connected to the 90 degree angle(a and b)), where as the second answer accounts for using the hypotenuse and one of the arms). That means that a 90 degree angle is involved, or as illustrated here, the square in the bottom right corner. If this were a non-right angle triangle, a different formula utilizing the height of the triangle would be used instead.

\(A = \frac{h_{b}+b}{2}\)

Since the right angle exists, a height is already given using one of the arms of the triangle in its place. We can also confirm it is a triangle by adding up all degrees of the triangle, in which it would equal 180 degrees confirming it is indeed a triangle as well.

By using trigonometric relations we will see that the area is:

How to find the area of one triangular section?

Remember that the area of a right triangle is equal to the product between the cathetus divided by 2.

Sadly, here we don't have the measures of any sides of the triangle, so getting the actual area is impossible, but if we assume that some dimension is given (like the height, let's say that is h).

h is the cathetus adjacent to the 60° angle, then the other cathetus (the bottom one) is given by:

tan(60°) = x/h

x = tan(60°)*h

Then our two catheti are h and tan(60°)*h.

This means that the area will be:

Here we only used trigonometric properties, so this area will work for any height given (always that the value of h is the cathetus adjacent to the 60° angle).

8.

7y - 4.5 - 6y

Combine like terms by subtracting

1y - 4.5

y - 4.5

4.5 does not have the same variable as the other term in the expression, therefore we cannot do anything further to it

9.

4x + 2 - 1/2x

Combine like terms by subtracting

One like term is a fraction so we must convert the whole number into a fraction with the same denominator

4/1x = ?/2

Cross multiply

4 × 2 = 1x × ?

8 = 2x

This is our new fraction: 8/2x because 4x = 8/2x

Substitute this new fraction into the expression

8/2x + 2 - 1/2x

Combine like terms by subtracting the numerators

7/2x + 2

Neither are like terms so they cannot be added together

Answer:

5 ft and 11 ft

Step-by-step explanation:

l= 2w+1

A=lw= 55

w(2w+1)=55

2w²+w-55=0

integer solution of quadratic equation is:

w=5 ft

l= 2*5+1=11 ft

Answer:

32 feet

Step-by-step explanation:

Start by creating your 2 equations

l = 2w + 1

l * w = 55

Plug in l, the isolated variable

(1 + 2w)w = 55

w + 2w² = 55

2w² + w -55 = 0

( − 5 ) ( 2 + 1 1 ) = 0

w= 5

w= -11/2 <- the width can't be negative so this one is out

Plug width into the area formula to find length

l * 5 = 55

l = 11

Answer:

A decimal sequence is a set of decimals that follow each other in order, and we use a rule, or pattern, to go from one number to the next. To find the rule for a sequence, we take two consecutive numbers and subtract them.

Answer:

Step-by-step explanation:

So I don't know if this will help or is the answer that you're looking for but here:

If you're multiplying a decimal by 1, it obviously stays the same.

ex: 1 x 0.25 = 0.25

If you multiply by 10 then you move the decimal place once to the right, as it gets bigger

ex: 10 x 0.25 = 2.5

you can do this for any number:

10 x 3.44 = 34.4

you can also use any power of 10.

10^2/100

100 x 2.75 = 275/275.0
