Solve for the value of w.
(w-8)°
(2W-1)º
Answer:
63
Step-by-step explanation:
[tex](w - 8) \degree + (2w - 1) \degree = 180 \degree \\ (linear \: pair \: \angle s) \\ (w - 8 + 2w - 1) \degree = 180 \degree \\ \\ (3w - 9) \degree = 180 \degree \\ \\ 3w - 9 = 180 \\ \\ 3w = 180 + 9 \\ \\ 3w = 189 \\ \\ w = \frac{189}{3} \\ \\ w = 63[/tex]

A girl has 11 coins in dimes and quarters. Their value is $1.55. How many quarters does she have?
8
3
5
Answer:
she has 3 quarters
Step-by-step explanation:
let's call the amount of dimes D
let's call the amount of quarters Q
you know that she has 11 coins in total,
so D + Q = 11.
you also know that each dime is worth 10 cents.
and each quarter is worth 25 cents.
so 10d + 25q = 155
this is a system of equations. solve by substitution:
d = 11 - q
10d + 25q = 155
10(11 - q) + 25q = 155
110 - 10q + 25q = 155
15q + 110 = 155
15q = 45
q = 45/15
q = 3

Step-by-step explanation:
is -27 divided by (-3) positive or negative & how
Answer:
It is positive (9)
Step-by-step explanation:
Negative ÷ negative = positive
Negative ÷ positive = negative
positive ÷ positive = positive
positive ÷ negative = negative
Negative × negative = positive
negative × positive = negative
positive × positive = positive
Positive × negative = negative
If both symbols are the same, it is positive. If one is positive and one is negative (different symbols), it is negative.
The result is 9. Since both the divisor (-3) and the dividend (-27) are negative, the final result is positive.
When dividing -27 by -3, the result is positive. In this case, the negative signs cancel out each other, and two negatives make a positive.
To understand why, think of division as the process of finding out how many times one number (divisor) can fit into another number (dividend). In this case, we are trying to find out how many times -3 can fit into -27.
-27 ÷ (-3) = 9
Here's the step-by-step calculation: -3 times 9 equals -27, which matches the dividend. So, the result is 9.
Since both the divisor (-3) and the dividend (-27) are negative, the final result is positive.
In conclusion, -27 divided by -3 is positive 9.

Serena brought a total of 135 notebooks and pencils for her students. Each notebook cost 1.75 and each pencil cost 0.35. The total cost of her purchase was 122.85. How many pencils did Serena buy?
Answer:
81 pencils
Step-by-step explanation:
1. Set up variables
Pencils = p
notebooks= n
2. Set up a system of equations
p+n= 135 (The amount of supplies bought)
1.75n +0.35p = 122.85 (Equation for the cost)
3. Solve the system of equations (I'll use substitution)
a)p= 135-n (I just rearranged it)
1.75n + 0.35p= 122.85
b) Substitute the first equation into the second)
1.75n + 0.35(135-n) = 122.85
c) Solve!
1.75n + 47.25 - 0.35n = 122.85
1.4n = 75.6
n= 54
Serena bought 54 notebooks!
4. Substitute the number of notebooks into the first equation
p +n = 135
p + 54= 135
p = 81
Serena bought 81 pencils!!!
I hope this helps!!!!
Answer:
Serena purchased 81 pencils
Step-by-step explanation:
Let x = the number of pencils Serena bought
Let 135 - x = the number of notebooks Serena bought
1.75(135 - x) + .35x = 122.85 Multiply both sides of this equation by 100.
175(135 - x) + 35x = 12,285
23,625 - 175x + 35x = 12,285
-140x = -11,340
x = 81 pencils

A bicycle wheel has a diameter of 559 mm and has 32 equally spaced spokes. What is the approximate arc length, rounded to the nearest hundredth, between each spoke? Use 3.14 for π . Show your work.
Answer:
Arc length = 54.85mm
Step-by-step explanation:
360/32 = 11.25
11.25 * 559 = 6288.75
6288.75 * 3.14 = 19746.675
19746.675/ 360 = 54.851875
Rounded to the nearest hundredth
Arc length = 54.85mm
The length of the arc is 54.9mm
Data given;
diameter = 559mm, r = d/2 = 279.5mmnumber of spokes = 32π = 3.14To solve this question, we have to use the formula of length of an arc which is given as
L = θ/360 * 2πr
To find the angle between each spoke, let's divide 360 by 32
[tex]\theta = 360/32\\\theta = 11.25^0[/tex]
Now that we have the value of the angle, let's substitute it and solve for the length of the arc.
[tex]L_a_r_c = \theta/360 * 2\pi r\\L_a_r_c = \frac{11.25}{360} * 2 * 3.14 * 279.5\\L_a_r_c = 54.9mm[/tex]
The length of the arc is approximately 54.9mm
