3/5a-1/2a=9/2
please help solve
for a and show work !!
Answer:
a = 45
Step-by-step explanation:
Start by changing the fractions so they share a common denominator to combine like-terms:
6/10a - 5/10a = 9/2
1/10a = 9/2
Multiply both sides by 10 to isolate a.
a = 90/2
a = 45
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

6. A camping tent is shown to the right. How much material would be needed to make the tent shown? (Use the formula S = Ph + 2B to solve). A. 144 centimeters squared B. 168 centimeters squared C. 181 centimeters squared D. 204 centimeters squared
Answer:
Option B
Step-by-step explanation:
The area of the two triangles in the tent is 2(B) = 2(1/2*6*4) = 2*12 = 24 cm^2
There are 3 rectangles left in the figure, two of which have the dimensions 5 by 9: 5*9 = 45, 45(2) = 90 cm^2
The other rectangle has the dimensions 6 by 9: 6*9 = 54 cm^2
S = 24+90+54 = 168 cm^2
Answer:
S = Ph + 2B
p=(5+5+6)=16cm
h=9cm
b=1/2 6×4=12cm²
Step-by-step explanation:
S = Ph + 2B=16×9+2×12=168cm²
please help (multiple choice question)
Answer:
5
Step-by-step explanation:
Since both triangles are similar then see if two dimension match up, so 9 is like 45, therefore, they multiplied 9 x 5 to get 45, so the scale factor (number you multiply to get the new value) is 5, since it grew 5 times

Answer:
x = 20°
Step-by-step explanation:
For questions like this, it is helpful to remember that an exterior angle is equal to the sum of the remote interior angles.
110° = 2x + 70°
40° = 2x
20° = x
_____
Similarly, ...
y = x + 70° = 20° +70°

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

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°.

Which equation represents circle A?
(x – 4)2 + (y + 5)2 = 12
(x + 4)2 + (y – 5)2 = 12
(x – 4)2 + (y + 5)2 = 36
(x + 4)2 + (y – 5)2 = 36
Answer:
c on edge
Step-by-step explanation:
just took the quiz
The equation representing the circle A is (x – 4)² + (y + 5)² = 36.
What is circle?A circle is a spherical shape without boundaries or edges. A circle is a closed, curved object with two dimensions in geometry.
The general equation of circle is given by equation
( x - h )² + ( y - k )² = r²
Where, ( h, k ) is the centre and 'r' is the radius.
As, the circle has a shift of 4 units on the +x axis.
The circle has a shift of the 5 units on the -y axis.
As, the circle has a radius of 6 units from the graph.
So, (h,k) = (4, -5).
Substitute the values of (h,k) in the general equation of the circle.
( x - 4 )² + ( y - (-5) )² = 6²
( x - 4 )² + ( y + 5 )² = 36
Therefore, the equation of circle becomes ( x - 4 )² + ( y + 5 )² = 36.
