Matthew plays soccer for h hours per day for five days in a row. Over the weekend, he played in a soccer tournament for a total of 6.5 hours. Which expression represents the number of hours Matthew played soccer in a full week? 5 + h + 6.5 5h + 6.5 StartFraction h over 5 EndFraction + 6.5 11.5hMariah purchases three hair barrettes by using a gift card, which starts with a balance of $35.79. Which expression models her purchase? 3 b minus 35.79 35.79 + 3 b 35.79 b minus 3 35.79 minus 3 b
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

(a).125m^3+27n^3+225m^2n+135mn^2
(B). 64a^3-144a^2b+108ab^2-27b^3
Plz answer, it's urgent.
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

Kelsea and Landon are playing in a park standing 100 feet away from each other. They both see a bird flying above them. The angles of elevation from each person to the bird are shown. How high is the bird from the ground? Round your answer to the nearest tenth. The angle for landon is 45 degrees the angle for kelsea is 20
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]
Which property is represented 7(t+u)= 7t + 7u
Answer:
distributive property
Step-by-step explanation:
The distributive property is
a(b + c) = ab + ac
where each term in the parenthesis is multiplied by the value outside.
Then
7(t + u) = 7t + 7u
What is the value for x=
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]
What are the answers to these two things? 3x -2 + 4 = x - 6 and x + 8 = 5x + 6 Im gonna need step by step also, thanks!
Answer:
For 3x-2+4=x-6
[tex]3x - 2 + 4 = x - 6 \\ 3x - x = - 6 - 4 + 2 \\ 2x = - 8 \\ x = \frac{ - 8}{2} \\ x = - 4[/tex]
for x+8=5x+6
[tex]x + 8 = 5x + 6 \\ x - 5x = 6 - 8 \\ - 4x = - 2 \\ x = \frac{ - 2}{ - 4} \\ x = \frac{1}{2} [/tex]

Subtract-3c2 + 12cd – 4d2 from 4c2 + 3cd + 2d?.
Your answer should be a polynomial in standard form.
Answer:
Subtract [tex]-3c^2 + 12cd - 4d^2[/tex] from [tex]4c^2 + 3cd + 2d^2[/tex] we get [tex]\mathbf{7c^2-9cd+6d^2}[/tex]
Step-by-step explanation:
We need to Subtract [tex]-3c^2 + 12cd - 4d^2[/tex] from [tex]4c^2 + 3cd + 2d^2[/tex]
(Note: Considering 2d^2 instead of 2d as thinking it typo error)
Subtracting from means we have to subtract [tex]4c^2 + 3cd + 2d^2 -(-3c^2 + 12cd - 4d^2)[/tex]
Subtracting:
[tex]4c^2 + 3cd + 2d^2 -(-3c^2 + 12cd - 4d^2)\\=4c^2 + 3cd + 2d^2 +3c^2 - 12cd + 4d^2[/tex]
Combining like terms (Like terms are those that have same variables like 4c^2 and 3c^2 are like terms, 3cd and -12cd are like terms, 2d^2 and 4d^2 are like terms)
[tex]=4c^2+3c^2 + 3cd-12cd + 2d^2+4d^2 \\=7c^2-9cd+6d^2[/tex]
So, Subtract [tex]-3c^2 + 12cd - 4d^2[/tex] from [tex]4c^2 + 3cd + 2d^2[/tex] we get [tex]\mathbf{7c^2-9cd+6d^2}[/tex]

Yesterday, the movie theater brought in $1,440 in ticket
sales and $295.25 in food sales. Today, ticket sales were
three-fourths as much as yesterday, and food sales were
down by $33.50. Nina wrote the expression
(1440) + 295.25 + (-33.50)
to find today's total sales. Is she correct? Explain.
Answer:
No. Nina forgot to adjust ticket sales.
Step-by-step explanation:
3/4(1440) + (295.25-33.50)
=1341.75
She didn't add the 1/4 less sales from the next day, Therefore she is wrong.
