A chef had 2 potatoes. How many bowls of mashed potatoes could he make if each bowl used one-half of a potato?
Answer:
4
Step-by-step explanation:
Since the chef has 2 potatoes and is using one-half of each, he can make a total of 4 bowls. By multiplying 2 * 2, you get 4.
By cutting the potatoes in half, the chef would now have 4 pieces.
In the figure shown below, line “m” and line “n” are parallel what is the value of x?
Answer:
x = 20°
Step-by-step explanation:
3x - 10° + 5x + 30° = 180° { being co-interior angles }
8x + 20 ° = 180°
8x = 180° - 20°
8x = 160°
x = 160° / 8
x = 20°

Work out the value of the missing angle x
Answer:
The value of the missing angle, x° is 115°
Step-by-step explanation:
The sum of the interior angles in a polygon is given by the formula (n - 2)×180, where, 'n', is the number of sides in the polygon
The number of sides in the given polygon, n = 10 sides
Therefore;
The sum of the interior angles in the polygon is (10 - 2)×180 = 1440°
The given angles of the polygon are;
107°, 126°, 325°, 125°, 95°, x°, 90°, 280°, 47°, and 130°
Therefore, we have;
107° + 126° + 325° + 125° + 95° + x° + 90° + 280° + 47° + 130° = 1440°
x° = 1440° - (107° + 126° + 325° + 125° + 95° + 90° + 280° + 47° + 130°) = 115°
The value of the missing angle, x° = 115°.

CAN ANYONE PLEASE (WHO IS AN EXPERT AT MATHEMATICS) HELP ME WITH THIS.
Please tell me what you get on this question. Let me know ASAP.
Answer:
5 units were bought
Step-by-step explanation:
Firstly, let us calculate the total amount paid
If what was paid was $9.45, this cost includes the price of the coupon subtracted
Returning the coupon price, we have the total as;
9.45 + 0.5 = $9.95
So to get the number bought, we divide this total by the price for one
We have this as;
9.95/1.99 = 5
Answer:
5 units
Step-by-step explanation:
9.95/1.99 = 5
Josh was able to type 496 words in 8 minutes. How many words can he type in 35 minutes?
Answer:
2170 words
Step-by-step explanation:
If we are assuming words and minutes are directly proportional to each other, we can say that w (words) = k (constant variable) x t (time in mins).
NOTE: directly proportional means that as one variable increases, the other variable increases too (or if one decreases, the other also decreases).K is the constant variable, which we must work out to find out any other time. If you rearrange the formula, it shows that k can be calculated by doing w/t. We have a set of values we can use to calculate k which are given in the question. So if we use this formula to calculate k, then:
k= w/t
k= 496/8
k= 62
Now we know the constant variable is 62. So, we go back to our equation but now we must find how many words. We now have our k value and our value for t. So, now we substitute:
w=kt
w= 62 x 35
w= 2170

someone has only quarters and dimes in his piggy bank. He has 152 coins in the piggy bank with the value of $30.50. Determine the system of equations that model this problem. Solve the system. How many quarters and dimes does Everett have
Answer:
102 quarters
50 dimes
Step-by-step explanation:
y = dimes
x = quarters
We can use the following equations to solve
[tex]152 = x + y[/tex]
[tex]30.5 = .25x + .10y[/tex]
We isolate for y in the first equation
[tex]y = 152 - x[/tex]
We plug into second equation
[tex]30.5 = .25x + .10(152 - x)[/tex]
Reduce
.15x = 15.3
x = 102
We then plug this number in first equation
152 = 102 + y
y = 50
Solve the system using elimination 4x+5y =2 -2x+2y=8

8
= 40/8
= 5
Answer:
5 m/s²
Step-by-step explanation:
v = 50 m/s
u = 10 m/s
t = 8 s
[tex]a = \frac{v - u}{t} [/tex]
a = (50 - 10) ÷ 8
a = 40 ÷ 8
a = 5 m/s²

Find the missing length of the right triangle.
C = ?
B = 8
A = 6
Answer:
10
Step-by-step explanation:
64 + 36 = c^2
Answer:
just use the pythagorean theorem.
c^2=a^2+b^2
substitute them.
c^2=64+36
c=root100
that is equal to 10
therefore missing side of triangle is 10
