Answer:
39
Step-by-step explanation:
Answer:
39 degrees
Step-by-step explanation:
by the triangle angle sum theorem, the 3 angles of triangles must add up to 180 degrees.
Therefore, 102 degrees + 39 degrees + x = 180 degrees
141 degrees + x = 180 degrees
x = 39 degrees

what is the radius if the circumference is 1.0
Answer:
r = 0.16
Step-by-step explanation:
C = 2·π·r
1 = 2·π·r
1/2 = π·r
0.5 = π·r
0.5 / 3.14 = r
0.16 = r

Sam had 1 1-2 m of rope. He cut off 5-8 m and used it for the project. How much does Sam have left
Which is the same as 0.25?
Answer:
[tex]\frac{25}{100}[/tex]
Step-by-step explanation:
Hey there !!!!!
to find the correct answer to this question you just divide :
the options are 25/10 , 2/5 , 10 / 25 and 25/100
so, you divide each one of them :
25/10 = 25 ÷ 10
2/5 = 2 ÷ 5
10/25 = 10÷25
25/100 = 25÷100
if you divide each one of them:
25 ÷ 10 = 2.5
2 ÷ 5 = 0.4
10÷25 = 0.4
25÷100 = 0.25
therefore:
25/100 is the answer

Evaluate the function. g(x) = 3x^2 – 2x + 5 Find f(2)
Answer:
13
Step-by-step explanation:
Replace X with 2
Evaluate the function. g(x) = 3x^2 – 2x + 5 Find f(2)
g(x) = 3(2)^2 – 2(2) + 5
Next conduct PEMDAS
Exponents are first so solve 2^2 which is 2 x 2 = 4
g(x) = 3(4) – 2(2) + 5
Next step is multiplication multiply 3 x 4 and 2x2
g(x) = 12 – 4 + 5
conduct adding and subtracting left from right
g(x) = 13

a machine at a graphic design studio produces paper labels for juice bottles. This graph represents the number of labels produced over time.
Based on the graph, how many labels are produced per minute?
50 labels/minute
75 labels/minute
100 labels/minute
150 labels/minute
Answer:
150 labels/ minute
Step-by-step explanation:
As you can see on the graph there is a point on (1,1 1/2)=150/1
Also 150*2=300 so it all makes sence

Kate has 48 softballs. She wants to divide them evenly among b softball bags. Which expression represents how many softballs she should put into each bag?
Answer:
Softballs = (48/b)
Step-by-step explanation:
Given that,
Total number of softballs = 48
She wants to divide them evenly among b softball bags.
We need to find an expression that represents how many softballs she should put into each bag.
As it is dividing among b softball, it means we divide 48 and b. So,
[tex]s=\dfrac{48}{b}[/tex]
Hence, the required expression is (48/b).
Maria's Grocery Store buys grapefruit at a cost
of 5 for a dollar. They sell them at a price of 5
for three dollars. How many must they sell in
order to make a profit of ten dollars?
Answer: 25 grapefruits
Step-by-step explanation:
They buy grapefruit at a price of 5 per dollar. This means that the price per grapefruit is:
= 1 / 5
= $0.20 per grapefruit.
They then sell at a price of 5 per $3. The selling price per grapefruit is:
= 3 / 5
= $0.60
The profit per grapefruit is:
= 0.60 - 0.20
= $0.40
In order to make a profit of $10, they should sell:
= 10 / 0.4
= 25 grapefruits

Let sin(2x)-sin(x)=0, where 0 ≤ x < 2pi. What are the possible solutions for x?
Step-by-step explanation:
sin2x - sinx = 0
2sinxcosx - sinx = 0
(Double Angle Formula)
sinx(2cosx - 1) = 0
Either sinx = 0 or cosx = 1/2.
When sinx = 0,
x = 0 or x = π.
When cosx = 1/2,
x = π/3 or x = 5π/3.
Hence the solutions are
x = 0, x = π/3, x = π or x = 5π/3.

Complete the solution of the equation. Find the
value of y when x equals 15.
-3x - y = -51
Answer:
The solution of the equation y = 36
Step-by-step explanation:
Explanation:-
Given equation -3x-y =-51
Given that x =15 in equation -3x-y=-51
⇒ - 3(15) - y = -51
⇒ - 15 - y =-51
⇒ -15+ 51 = y
⇒ y = 36
