Answer:

Part(A): The expression which represents the number of hours Matthew played soccer in a full week is [tex]5h + 6.5[/tex]

Part(B): the expression models her purchase is [tex]35.79-3b[/tex].

Step-by-step explanation:

Consider the provided information.

Part(A):

Matthew plays soccer for h hours per day for five days and he played a soccer tournament for a total of 6.5 hours.

So the required expression is: [tex]5h + 6.5[/tex]

Where 5h represents time spent in 5 days and 6.5 is the hours of the soccer tournament.

Part(B):

Mariah purchases three hair barrettes by using a gift card.

Let the cost of each barrette is b.

So the cost of 3 barrettes is: [tex]3b[/tex]

She uses a gift card with a balance of $35.79. Therefore subtract  [tex]3b[/tex] from $35.79.

Her purchase can be expressed as:

[tex]35.79-3b[/tex]

Hence, the required expression is [tex]35.79-3b[/tex].

Answer:

5h + 6.5

Answer:

x = 2[tex]\sqrt{5}[/tex]

Step-by-step explanation:

Since the 2 legs are congruent, both 6 then the triangle is isosceles.

The line from the vertex to the base is a perpendicular bisector, dividing the base into 2 parts of 4 units.

Using Pythagoras' identity in one of the right triangles.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 4² = 6²

x² + 16 = 36 ( subtract 16 from both sides )

x² = 20 ( take the square root of both sides )

x = [tex]\sqrt{20}[/tex] = [tex]\sqrt{4(5)}[/tex] = 2[tex]\sqrt{5}[/tex]

Answer:

26.68 ft

Step-by-step explanation:

Let a represent the distance from Kelsea to the bird and b be the distance from Landon to the bird.

Let x = angle of the bird. Hence:

x + 45 + 20 = 180 (sum of angles in a triangle)

x + 65 = 180

x = 180 - 65

x = 115°

Using sine rule:

[tex]\frac{100\ ft}{sin(115)} =\frac{a}{sin(45)} =\frac{b}{sin(20)} \\\\\frac{100\ ft}{sin(115)} =\frac{a}{sin(45)}\\\\a=\frac{100\ ft}{sin(115)} *sin(45)\\\\a=78\ ft\\[/tex]

Let h = height of the bird to the ground. Since a right angle is formed. hence:

[tex]\frac{h}{sin(20)} =\frac{78}{sin(90)} \\\\h=\frac{78}{sin(90)}*sin(20)\\\\h=26.68\ ft[/tex]

Answer:

  D.  a ║ b

Step-by-step explanation:

If we figure the other angle of each linear pair, we can directly compare angles to see if corresponding angles are the same. Where they are the same, the lines are parallel.

  Line a is parallel to line b.

Answer:

a)(5m+3n)^3 b)(4a-3b)^3

Step-by-step explanation:

a)125m^3+27n^3+225m^2 n+135mn^2

Use the binomial cube formula, a^3+3a^2

b+3ab^2+b^3=(a+b)^3, where a=5m and b=3n.

(5m+3n)^3

b)64a^3-144a^2 b+108ab^2-27b^3

Use the binomial cube formula, p^3-3p^2q+3pq^2-q^3=(p-q)^3, where p=4a and q=3b.

(4a-3b)^3

Answer: Hi, sorry if I’m late to answering but the answer is 19

Step-by-step explanation:

You divide each number in the equation by 5. So, 5x divided by 5 = 1. We cannot use 5 divided by 5 because it will equal 1 so we ignore that and go to 95 divided by 5 = 19. Therefore, 19 is your answer!!! (Hope this helped)

Answer:

x = 8

Step-by-step explanation:

well using the theorem we have

[tex]\frac{6}{9}=\frac{x}{12}\\\\\frac{2}{3}=\frac{x}{12}\\\\12[\frac{2}{3}]=12[\frac{x}{12}]\\\\4\cdot 2=x\\\\x=8[/tex]
