Answer:
- 1/4
Step-by-step explanation:
7a + 2 = 3a + 1
subtract the 1 from both sides
7a + 1 = 3a
subtract 7a from both sides
1 = - 4a
divide by - 4
A = - 1/4

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

wich expression is equivalent to 2,3/5 divided by 7/9
Answer:
117/35 is equalivent expression
Step-by-step explanation:
2 3/5 divided by 7/9
so you need to make 2 3/5 into a fraction
you do the denominator time the whole number plus the numerator to get 13/5
13/5 / 7/9
when you divided fractions you flip the seccond fraction and multiply to get....
13/5 times 9/7
so you do. 13 times 9 and 5 times 7
you get 117/35

Step-by-step explanation:
A drum used for percussion has sides modeled by a hyperbola. The total height of the drum is 35 inches. The diameter at the top of the drum is 16 inches, and the minimum diameter is 8 inches, occurring at a height of 22 inches. Determine the equation of a hyperbola that models the sides of the drum assuming that the center of the hyperbola occurs at the height where the diameter is the least.
look at the screen shot ya know
The equation of a hyperbola that models the sides of the drum assuming that the center of the hyperbola is (35 + a)²/a² - 8²/b² = 1 and (22+ a)²/a² - 4²/b² = 1
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that the total height of the drum is 35 inches.
The diameter at the top of the drum = is 16 inches, and
The minimum diameter is 8 inches, occurring at a height of 22 inches.
The equation of the hyperbola be denoted as;
x²/a² - y²/b² = 1
From the question, with x and y coordinates representing height and radius respectively,
Then,
When x = 35 + a, y is = 16/2 = 8 and
At x = 22+ a, y is = 8/2 = 4
Thus,
(35 + a)²/a² - 8²/b² = 1
(22+ a)²/a² - 4²/b² = 1
By solving, we have, a = 128.95 and b = 14.75
Therefore a= 128.95 and b = 14.75

Write the equation of a line that passes through the point (1,4) and has a slope of 9.
Answer:
y=9x-5
Step-by-step explanation:
You want to find the equation for a line that passes through the point (1,4) and has a slope of 9.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
To start, you know what m is; it's just the slope, which you said was 9. So you can right away fill in the equation for a line somewhat to read:
y=9x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(1,4). When x of the line is 1, y of the line must be 4.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: b is what we want, the 9 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specifically passes through the point (1,4).
So, why not plug in for x the number 1 and y the number 4? This will allow us to solve for b for the particular line that passes through the point you gave!.
(1,4). y=mx+b or 4=9 × 1+b, or solving for b: b=4-(9)(1). b=-5.The equation of the line that passes through the point (1,4) with a slope of 9
is
y=9x-5

JK, KL and LJ are all tangent to O (not drawn to scale). JA = 13, AL = 9, and
CK = 11. Find the perimeter of JKL.
a.)66
b.)44
c.)33
d.)48
Answer:
a.) 66
Step-by-step explanation:
Perimeter of JKL = JA + AL + CK + CL + KB + JB
JA = 13,
AL = 9,
CK = 11
CL = AL = 9 (tangents drawn from an external point are congruent)
KB = CK = 11 (tangents drawn from an external point are congruent)
JB = JA = 13 (tangents drawn from an external point are congruent)
Plug in the values
Perimeter of JKL = 13 + 9 + 11 + 9 + 11 + 13
= 66

What are the two whole numbers whose product is 294 and whose quotient is 6?
Answer: 7 and 42.
Step-by-step explanation:
Let the two whole numbers be x and y.
From the question given, we can form an equation as:
x × y = 294 ........ i
x/y = 6 .......... ii
From equation ii
x/y = 6
x = 6y
Put the value of x back into equation i
x × y = 294
6y × y = 294
6y² = 294
y² = 294/6
y² = 49
y = ✓49
y = 7
Since x × y = 294 and y = 7,
x = 294/7
x = 42
The numbers are 7 and 42.
Match each indicated measure in the first column for
⊙
O
⊙O.
Answer:
Step-by-step explanation:
By the property,
"Measure of the intercepted arc is double of the inscribed angle"
m(arc BC) = 2×48°
= 96°
By using the same property,
m(arc AC) = 2 × m(∠B)
m(∠B) = [tex]\frac{110}{2}[/tex]
= 55°
m(∠A) + m(∠B) + m(∠C) = 180° [Triangle sum theorem]
48° + 55° + m(∠C) = 180°
m(∠C) = 180° - 103°
= 77°
m(arc AB) = 2 × (m∠C)
= 2×77
= 154°
