Answer:
A. 55°
Step-by-step explanation:
So the line goes through two angles, 125° and 55°
Lets check, does the angle look larger than 90°
Remember, 90° mean the line is perpendicular, or goes straight up.
I see that it is not. The angle that is less than 90° (55°) is correct.

Doug needs to order 25,000 g of a
supplement. At the store,
supplements come in 5 kg packages
that cost $80 each. What will Doug's
order cost?
Answer:
$2000
Step-by-step explanation:
1,000 g would be = 1 Kg so it would be 25 Kg
And 25 X 80 = 2000
Answer:
$400
Step-by-step explanation:
25,000 grams is equal to 25 kg, so if 5 kg equals $80, the total 25 kg divided by 5 equals five. With this you multiply; 5 × 80 kg = 400. So $400 is the answer.

Answer:
7.1
Step-by-step explanation:
Use the trig ratio tan to find b
4.5 x tan (23) = b = 7.14668887526
7.1
Answer:
b ≈ 1.9
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan23° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{b}{4.5}[/tex] ( multiply both sides by 4.5 )
4.5 × tan23° = b , then
b ≈ 1.9 ( to the nearest tenth )
There are
15
apples in a basket.
6
of these apples are green. The rest of them are red.
(a) What is the ratio of red apples to all apples in the basket?
(b) What is the ratio of green apple to red apples?
Answer:
(a) 9:15
(b) 6:9
Step-by-step explanation:
Total apples: 15
6 : green
9 are red
9:15
6:9
Answer:
(a) 3 : 5
(b) 2 : 3
Step-by-step explanation:
green apples = 6 total apples = 15 red apples = 15 - 6= 9 apples
(a) red apples : all apples= 9 : 15
for simplified form dividing numerator and denominator by 3
= 3 : 5
(b) green apples : red apples= 6 : 9
for simplified form dividing numerator and denominator by 3
= 2 : 3
In a certain class, percentage of students who increased their average grade during spring term compared to that of the fall term was recorded between 6.9% and 7.1%. What could be the least possible number of students in that class?
Answer:
No, you have to consider that if 1 student in 14/15 cannot represent a percentage between .69 and .71, how could 2 students do the job? You have to have an integer number of students.
2/18 = 1/14 = 7.14%
2/29 = 6.89%
Still out of bounds
What about 3 students?
3/42 = 1/14 = 7.14%
3/43 = 6.97%
3/44 = 6.81%
So, it looks like 43 is the minimum number of students.

Nelda baked two kinds of pasta in pans. Each pan was the same size. She sliced one pan of pasta into 4 equal pieces. She sliced the other pan into 6 equal pieces. How can the pans of pasta now be sliced so that both pans have the same-sized pieces? If Nelda has served 8 pieces from 1 pan so far, what fraction of 1 pan has she served?
Answer:
6 equal parts; 8 equal parts
Both those will go into 24.
Step-by-step explanation: Each of six slices of the first pasta has the area 1%2F6 of the entire pan.
Each of eight slices of the second pasta has the area 1%2F8 of the original pan.
Nelda will cut each 1%2F6 in 4 equal pieces to get 1%2F24.
She also will cut each 1%2F8 in 3 equal pieces to get 1%2F24.
solve the equation by completing the square. Round to the nearest hundredth if necessary.

_____ + 15 − 15 = 21
help mee
Answer:
x = 21
Step-by-step explanation:
x + 15 - 15 = 21
+ 15 and - 15 cancel out
So x = 21
Let's solve the longer way
x + 15 - 15 = 21
x + 15 = 21 + 15 . (adding 15 to both sides)
x = 21 (Subtracting 15 from both sides)

Well done!!
A ball is thrown up in the air, and it's height (in feet) as a function of time (in seconds) can be written as h(t) = -16t2 + 32t + 6. Describe in detail (using formulas and/or specific steps needed) TWO ways to find the maximum height reached by the ball.
Answer:
1) Using properties of the quadratic equation:
Here the height equation is:
h(t) = -16t^2 + 32t + 6
We can see that the leading coefficient is negative, this means that the arms of the graph will open downwards.
Then, the vertex of the quadratic equation will be the maximum.
Remember that for a general quadratic equation:
a*x^2 + b*x + c = y
the x-value of the vertex is:
x = -b/2a
Then in our case, the vertex is at:
t = -32/(2*-16) = 1
The maximum height will be the height equation evaluated in this time:
h(1) = -16*1^2 + 32*1 + 6 = 22
The maximum height is 22ft
2) Second method, using physics.
We know that an object reaches its maximum height when the velocity is equal to zero (the velocity equal to zero means that, at this point, the object stops going upwards).
If the height equation is:
h(t) = -16*t^2 + 32*t + 6
the velocity equation is the first derivation of h(t)
Remember that for a function f(x) = a*x^n
we have that:
df(x)/dx = n*a*x^(n-1)
Then:
v(t) = dh(t)/dt = 2*(-16)*t + 32 + 0
v(t) = -32*t + 32
Now we need to find the value of t such that the velocity is equal to zero:
v(t) = 0 = -32*t + 32
32*t = 32
t = 32/32 = 1
So the maximum height is at t = 1
(same as before)
Now we just need to evaluate the height equation in t = 1:
h(1) = -16*1^2 + 32*1 + 6 = 22
The maximum height is 22ft

Answer:
a) see attached
b) 1/3
Step-by-step explanation:
Your grid doesn't come with any coordinate axes, so you will need to draw those and label them. You will also need to determine the number of grid squares for each unit. (I suggest 2 grid squares per unit to give you a little more distance between the points you plot. The attachment shows 5 small squares per unit. You may not have this much space on your graph.)
Plot the points. Once you do this, you can see that their horizontal difference is 3 units and their vertical difference is 1 unit. The right point is above the left point, so the slope is positive:
m = (rise)/(run) = 1/3 . . . slope of the line

Answer:
The polygons are similar.
Step-by-step explanation:
By definition, the corresponding sides and angles of similar polygons must be in some constant proportion.
Therefore, we can find the ratio between corresponding sides to see if that ratio is maintained.
The side marked 3 cm in the smaller figure corresponds with the side marked 3.75 cm in the larger figure. This proportion is [tex]\frac{3}{3.75}[/tex].
The side marked 5 in the smaller figure corresponds with the side marked 6.25 cm in the larger figure. This proportion is [tex]\frac{5}{6.25}[/tex].
If these polygons are similar, these proportions must be equal.
[tex]\frac{3}{3.75}=\frac{5}{6.25},\\0.8=0.8\:\checkmark[/tex]
Checking, we see that these proportions are equal, and therefore the polygons are similar.

The volume, of the cement used to make the sidewalk is 8 ft³
What is volume?Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also known as the capacity of the object.
Given that, James is using cement to make a new sidewalk and new steps,
He will make a new rectangular sidewalk that is 8 feet long, 4 feet wide, and 0.25 foot thick.
Volume = length x width x height
Volume = 8 x 4 x 0.25 = 8 ft³
Hence, the volume, of the cement used to make the sidewalk is 8 ft³

Step-by-step explanation:
The hardest part about negative numbers in addition is remembering when to add, rather than subtract. In the last equation, we add the numbers together, because the negative sign cancels out with subtraction. All of the other equations we can follow exactly what it says to do, because there are no minus signs right next to each other.

The system of equation is:
[tex]-2x+4y=16[/tex]

To find:
The solution of the given system of equations.
Solution:
We have,
[tex]-2x+4y=16[/tex] ...(i)
[tex]2x+2y=8[/tex] ...(ii)
Add (i) and (ii) to eliminate the variable x.
[tex]6y=24[/tex]
[tex]y=\dfrac{24}{6}[/tex]
[tex]y=4[/tex]
Putting [tex]y=4[/tex] in (ii), we get
[tex]2x+2(4)=8[/tex]
[tex]2x+8=8[/tex]
[tex]2x=8-8[/tex]
[tex]2x=0[/tex]
Divide both sides by 2.
