Answer:
[tex]\frac{3}{5} *5[/tex] or [tex]5*\frac{3}{5}[/tex]
Step-by-step explanation:
Each circle has 3/5 shaded, and there are 5 circles.
So our multiplication equation is:
[tex]\frac{3}{5} *5[/tex] or [tex]5*\frac{3}{5}[/tex] (they mean the same thing)
[tex]\frac{3}{5} *5=3[/tex]

what is the value of the expression (y+6)*7
Answer:
7y+42
Step-by-step explanation:
If I am doing this correctly (so take it with a grain of salt from just waking up) you would multilpy 7 with the expressions in the ( )
So it would be 7*y= 7y
Then 7*6= 42
So it would be 7y+42 I think
Sorry if it is incorrect/ doesn't answer your question. Good luck!
Answer:
[tex]\displaystyle \large{7y+42}[/tex]
Step-by-step explanation:
We are given the expression [tex]\displaystyle \large{(y+6) \cdot 7}[/tex]. Use the distributive property to simplify the expression.
Distributive Property
[tex]\displaystyle \large{a(b+c)=ab+ac}[/tex]
To say it simply, you multiply the outside with the insides. Therefore, from the expression:-
[tex]\displaystyle \large{y \cdot 7 + 6 \cdot 7}[/tex]
Evaluate:-
[tex]\displaystyle \large{\boxed{7y+42}}[/tex]

Find the 12th term of the arithmetic sequence x−4, 3x−11, 5x-18, ...
Answer:
Step-by-step explanation:
x -4 , 3x-11 , 5x - 18 ,.......
first term = a = x -4
Common difference (d) = second term - first term
= 3x -11 - [ x - 4]
= 3x - 11 - x + 4
= 3x - x - 11 + 4
= 2x - 7
nth term = a + (n-1)*d
12th term = x - 4 + 11*(2x - 7)
= x - 4 + 11*2x - 7 *11
= x - 4 + 22x - 77
=x + 22x - 4 - 77
= 23x - 81
The volume of a rectangular prism is 48 cubic meters. It is 6 meters long and 2 meters wide.
What is the area of the base of the prism?
Answer:
12m^2
Step-by-step explanation:
volume = 48 m^3
l*b*h = 48
12*h = 48
h = 4 m
baSe of prism will be made of l and b
so area is 12 m^2
go step by step to reduce the radical
[tex]\sqrt300[/tex]
Answer:
10√3
Step-by-step explanation:
First we do the prime factorisation of 300:
2²×3×5²
Now we put this into our surd:
[tex]\sqrt{(2^{2})(3)(5^{2}) }[/tex]
Now we split them up:
[tex]\sqrt{2^{2} } \sqrt{3} \sqrt{5^{2} }[/tex]
Now we apply the radical rule of [tex]\sqrt{a^{2} } = a[/tex] if a ≥ 0, for 2 then 5
√2² = 2
√5² = 5
2√3 ×5
Simplify to get

help me please I need more math time.
Answer:
7m = t, 42, 56
Step-by-step explanation:
If each mile takes 7 minutes, then the chart is correct in saying that 4 miles takes 28 minutes (7 • 4 = 28)Using this information, we can set up the equation with the knowledge that 7m = t (or, one mile takes 7 minutes)The blanks would be 42 and 56 because we multiply M by 7 each time to get T. For example, we would multiply 6 by 7 to get 42 minutes.If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.

Keecia joins a gym. She pays a membership fee of $75.00 and $49.99 per month for the first 8 months. The gym increases its rates, and she must pay $59.99 per month for the next 4 months. Which numerical expression can be used to find the total cost of the first year of Keecia’s gym membership?
Answer:
$165 is the total cost of the first year of Keecia’s gym membership
Step-by-step explanation:
formula for direct proportion : y = kx
x = 50
y = 75
50 = k * 75
k = 75/50
k = 3/2x
substitute y = 60
60 = 3/2x
x = 3/2 * 60
x = 90
$90 + $75 = $165

Answer:
B. Yes.
C. Yes.
Step-by-step explanation:
B. In this, it is saying basically is "2b + b = 3b." Well yes, because 2b + b = 3b. So 3b = 3b? Yes.
C. So same thing. 2b + b = 3b. 3b = 3b. they are equivalent.

Katie owns a pretzel stand. Her profit, in dollars, is given by the function , where is the number of pretzels sold. What is the maximum profit , in dollars, Katie can earn?
Using the vertex of the quadratic equation, it is found that the maximum profit she can earn is of $106.
What is the vertex of a quadratic equation?A quadratic equation is modeled by:
[tex]y = ax^2 + bx + c[/tex]
The vertex is given by:
[tex](x_v, y_v)[/tex]
In which:
[tex]x_v = -\frac{b}{2a}[/tex]
[tex]y_v = -\frac{b^2 - 4ac}{4a}[/tex]
Considering the coefficient a, we have that:
If a < 0, the vertex is a maximum point.If a > 0, the vertex is a minimum point.In this problem, her profit is modeled by:
[tex]P(x) = -x^2 + 14x + 57[/tex]
Which is a quadratic equation with coefficients a = -1, b = 14, c = 57, hence, her maximum profit in dollars is given by:
[tex]y_v = -\frac{14^2 - 4(-1)(57)}{4(-1)} = 106[/tex]
