Seth’s bank charges $5 a month to maintain a checking account and $0.50 for each check Seth writes. Last month, Seth paid a total of $6.50 in checking account fees. How many checks did he write?
A 1 C 3
B 2 D 4
Answer:
13
Step-by-step explanation:
Since Seth pays $0.50 for each check he writes, he would write (let x be how many checks Seth wrote) "x" checks for $6.50. That means;
1 = 0.50
x = 6.50
Now let us set up a fraction:
[tex]\frac{0.5}{1}=\frac{6.5}{x}[/tex]
Step 1: Cross multiply
[tex]0.5x=1\cdot \:6.5[/tex]
[tex]0.5x=6.5[/tex]
Step 2: Divide both sides by [tex]0.5[/tex]
[tex]\frac{0.5x}{0.5}=\frac{6.5}{0.5}[/tex]
Simplify
[tex]x=13[/tex]
Therefore, Seth will write 13 checks for $6.50

- 28 – 6b= 8
Answer:
-6
Step-by-step explanation:
- 28 – 6b= 8
step 1 add 28 to each side
-28 + 28 cancels out
28 + 8 = 36
we now have -6b = 36
step 2 divide each side by -6
-6b / -6 = b
36 / -6 = -6
we're left with b = -6
Hi there!
»»————- ★ ————-««
I believe your answer is:
[tex]b=-6[/tex]
»»————- ★ ————-««
Here’s why:
We will have to preform inverse operations to solve for 'b'.
[tex]\boxed{\text{Solving the equation for 'b':}}\\\\-28-6b=8\\\\--------\\\rightarrow-28+28-6b=8+28\\\\\rightarrow-6b=36\\\\\rightarrow\frac{-6b=36}{-6}\\\\\rightarrow \boxed{\text{b=-6}}\\\\\text{The value of 'b' is \boxed{-6}.}[/tex]

How many 2-digit numbers are multiples of 5 but not 4?
Answer:
14
Step-by-step explanation:
The numbers you are describing can end in 5. But there are others as well. They are t = 10 + 20*n where n goes from 0 to 4. So if n is 4 that means that t = 4*20 + 10 = 80 + 10 = 90.
Solution
15 25 35 45 55 65 75 85 95 are all divisible by 5 but not 4
10 30 50 70 90 are all divisible by 5 but not 4

Step-by-step explanation:
Mahmoud is working out the height, h metres, of a tower
BT which stands on level ground.
He measures the angle TAB as 25°.
He cannot measure the distance AB and so he walks 80 m
from A to C, where angle ACB = 18° and angle ABC = 90°.
Calculate
Answer:
24.72 m
11.53 m
Step-by-step explanation:
Horizontal distance AB can be obtained from △ABC
From trigonometry :
Sin18° = opposite / hypotenus
Sin18° = AB / 80
AB = 0.3090169 * 80
AB = 24.72 m
The height BT, of tower from △ABT
From trigonometry :
Tan25° = opposite / Adjacent
Tan25° = h / 24.72m
h = Tan25 * 24.72
h = 11.527
h = 11.53 m
Hence, height of tower BT = 11.53 m

Answer:
A. 44/625
Step-by-step explanation:
There are 25 marbles total. To first calculate the probability of picking a yellow marble first can be represented as 11/25, the probability of picking blue is 4/25. We multiply these to figure out the probability of finding a yellow marble and then a blue one.
11/25 x 4/25 = 44/625

Answer:
E
Step-by-step explanation:
Cos=Adjacent/hypotenuse
Cos30=rad3/2
The cosine function for Ф = 30 is equivalent to :
cos(30) =√3/2.
What are trigonometric functions?There are six major trigonometric functions as -
Sine(x)Cosine(x)Tangent(x)Cotangent(x)Secant(x)Cosecant(x)We can write the relation between them as -
Sine = 1/cosecantCosine = 1/secantTangent = 1/CotangentAlso the following trigonometry relations hold true -
sin²Ф + cos²Ф = 1
1 + tan²Ф = sec²Ф
1 + cot²Ф = cosec²Ф
Given is a right angled triangle as shown in the image having 60 - 90 - 30 orientation and the measured sides as shown in the image.
We can write the cosine function as -
cosФ = Base/Hypotenuse
cos(30) = √3/2
So, we can conclude that the cosine function for Ф = 30 is equivalent to :
cos(30) =√3/2
Therefore, the cosine function for Ф = 30 is equivalent to :
cos(30) =√3/2.

Your friend has n pennies. You have 29 pennies. You and your friend have a total of 40 pennies. Which equation could be used to find n?
Answer:
40-29=n
Step-by-step explanation:
You have 29 in total yall have 40
so to find ur friends we subtract
Answer:
Step-by-step explanation:
your pennies + your friends pennies = the total number of pennies between you two
so the equation would be :
29 + n = 40
(im not sure if you wanted it solved for n but here is the solution just in case)
29 + n = 40
n = 40 - 29
n = 11

Hey!! Can any of y'all help me find the center and radius of this equation?
x^2+y^2-8x+2y=-8
Answer:
Center: (4,-2)
Radius: 2√3 units
Step-by-step explanation:
We wish to find the center and radius of the equation x²+y²-8x+2y=-8
Step 1: Complete the square for both variables:
x²+y²-8x+2y=-8
x²-8x+y²+2y=-8 (Rearrange)
x²-8x+16+y²+2y+4=-8+16+4 (Add to both sides)
(x-4)²+(y+2)²=12 (Reduce trinomials)
Step 2: Interpret the center and radius of the circle:
The equation of a circle is (x-h)²+(y-k)²=r² where (h,k) is the center of the circle and r is the radius of the circle. Since (h,k) translates to (4,-2), this means the center of the circle is (4,-2). Since r²=12, then r=√12=2√3 units

Wich of the following equations would NOT contain the point (4,12)
Given:
The given point is (4,12).
To find:
The equation that would NOT contain the point (4,12).
Solution:
We need to check each equation for the point (4,12).
In option A, the given equation is:
[tex]y=-2x+20[/tex]
Putting [tex]x=4[/tex], we get
[tex]y=-2(4)+20[/tex]
[tex]y=-8+20[/tex]
[tex]y=12[/tex]
This equation contains the point (4,12).
In option B, the given equation is:
[tex]y=\dfrac{1}{2}x+8[/tex]
Putting [tex]x=4[/tex], we get
[tex]y=\dfrac{1}{2}(4)+8[/tex]
[tex]y=2+8[/tex]
[tex]y=10[/tex]
This equation does not contain the point (4,12).
In option C, the given equation is:
[tex]y=-\dfrac{1}{2}x+14[/tex]
Putting [tex]x=4[/tex], we get
[tex]y=-\dfrac{1}{2}(4)+14[/tex]
[tex]y=-2+14[/tex]
[tex]y=12[/tex]
This equation contains the point (4,12).
In option D, the given equation is:
[tex]y=\dfrac{3}{4}x+9[/tex]
Putting [tex]x=4[/tex], we get
[tex]y=\dfrac{3}{4}(4)+9[/tex]
[tex]y=3+9[/tex]
[tex]y=12[/tex]
This equation contains the point (4,12).
Only the equation in option B does NOT contain the point (4,12). Therefore, the correct option is B.
