LCM is 35 because 7 * 5 =35
[tex]\frac{5}{7}=\frac{5\cdot \:5}{7\cdot \:5}=\frac{25}{35}[/tex]
[tex]\frac{3}{5}=\frac{3\cdot \:7}{5\cdot \:7}=\frac{21}{35}[/tex]
[tex]\frac{25}{35}+\frac{21}{35}=\frac{25+21}{35}[/tex]
[tex]=\frac{46}{35}[/tex]
change the improper fraction into mixed number
[tex]6+1\frac{11}{35}[/tex]
[tex]=7\frac{11}{35}[/tex]

Step-by-step explanation:
Rotational symmetry is when a shape has the same orientation after being rotated.
For example, an equilateral triangle rotated 120° will line back up with itself. A square rotated 90° will also return to its original orientation. Same with a pentagon rotated 72°.
Basically, an n-gon rotated by a multiple of 360°/n will return to its original position.
θ = k 360°/n
For the first rotation:
160° = k 360°/n
160 / 360 = k / n
4/9 = k/n
For the second rotation:
120° = k 360°/n
120 / 360 = k / n
1/3 = k/n
For the third rotation:
80° = k 360°/n
80 / 360 = k / n
2/9 = k/n
For the fourth rotation:
280° = k 360°/n
280 / 360 = k / n
7/9 = k/n
The total rotation angle is -160°.
160 = k 360/n
160 / 360 = k / n
4/9 = k/n
Comparing the denominators, n must be the smallest multiple of 3 and 9. Therefore, n = 9.

You order two tacos and a salad costs $2.50 you pay 8% sales tax and leave a $3 tip you pay a total of $13.80 how does one taco cost
Answer:
One taco costs $3.75.
Step-by-step explanation:
Let x = cost of taco
You order 2 tacos: 2x
You add a salad: 2x + 2.5
You pay 8% sales tax on 2x + 2.5, so you pay 1.08(2x + 2.5)
You leave a $3 tip, so the total you pay is: 1.08(2x + 2.5) + 3
The total you pay is $13.80
1.08(2x + 2.5) + 3 = 13.80
Subtract 3 from both sides.
1.08(2x + 2.5) = 10.8
Divide both sides by 1.08
2x + 2.5 = 10
Subtract 2.5 from both sides.
2x = 7.5
x = 3.75
One taco costs $3.75.
A survey found that 8 out of 10 parents approved of the new principals performance.If 14 parents names are chosen with replacement what is the probability they all approve of the principals performance
Answer:
The probability is 0.044
Step-by-step explanation:
Let p be the probability that the new principal’s performance is approved.
This is obtainable from the survey and it is 8/10 = 0.8
Let q be the probability that the new principal’s performance is disproved.
That will be;
1 - q = 1- 0.8 = 0.2
To calculate the probability that 14 parents names are chosen at random and they all
approve of the principal’s performance, we use the Bernoulli approximation of the binomial theorem.
That will be;
14C14 * p^14 * q^0
= 1 * 0.8^14 * 0.2^0
= 0.043980465111 which is approximately 0.044

∠1 and ∠2 are vertical angles. If the measure of ∠2 is 105°, find the measure of ∠1.
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{105°}}}}}[/tex]
Step-by-step explanation:
Given, < 2 = 105°
To find : < 1
When two lines interest the angles formed opposite to each other are called vertically opposite angles. Vertically opposite angles are always equal to each other.
So,
<1 = 105 °
Hope I helped!
Best regards!
Answer:
[tex]\Huge \boxed{\angle 1 = 105 \° }[/tex]
Step-by-step explanation:
[tex]\angle 1[/tex] and [tex]\angle 2[/tex] are vertical angles.
[tex]\angle 2= 105 \°[/tex]
Vertical angles are equal in measure.
[tex]\angle 1= \angle 2[/tex]

I plugged in 4 for the derivative function but I’m getting the wrong answer?
Answer:
8.6615988
Step-by-step explanation:
f(x) = 3 sin (x) / ( 1 + cos x)
To find the derivative bottom * d/ dx top - top d/dx bottom all over the bottom squared
d/dx = 3 ( ( 1 + cos x) cos x - sin x( - sin x)) / ( 1 + cos x) ^2
= 3 ( cos x + cos ^2 x + sin ^2 x) / ( 1 + cos x) ^2
= 3 ( 1 + cos x) / ( 1 + cos x) ^2
= 3 / ( 1 + cos x)
Let x = 4
3 / ( 1 + cos 4)
Assuming x is in radians

Estimate the addition by rounding each number to the nearest hundred thousand. Then find the sum. Estimate: 229,275 +115,368 344633
Answer:
600,000
Step-by-step explanation:
When rounding to the nearest 100,000 if it's X50,000 you round up 1 for the X, if it's X49,999 or less you keep the X as is.
229,275 rounding to the hundred thousand would be 200,000
115,368 would be 100,000
344,633 would be 300,000
so 200,000+100,000+300,000 = 600,000
Write the possible range of each measurement to the nearest tenth. Include unit measure. Round to the tenths place.
60 m ± 4.5%
__?__ - __?__
Answer:
60.0m≤60.1mStep-by-step explanation:
Given the interval for the measurement to be 60 m ± 4.5%, the posible range of each measurement is expressed as shown;
60 m ± 4.5% = 60 m ± 4.5/100
= 60 m ± 0.045
= (60 - 0.045, 60+0.045)
= (59.955, 60.045)
Hence possible range of each measurement to the nearest tenth is (60.0m≤60.1m)
p = q/4 -r solve for q
Answer:
4(p+r) = q
Step-by-step explanation:
p = q/4 -r
Add r to each side
p+r = q/4 -r+r
p+r = q/4
Multiply each side by 4
4(p+r) = q/4*4
4(p+r) = q

A line with a slope of 3 passes through (2,5). Which choice is an equation of this line? Please help
Answer:
Top right.
Step-by-step explanation:
So we want a line with a slope of 3 and passes through (2,5).
To do so, we can use the point-slope form.
The point-slope form is:
[tex]y-y_1=m(x-x_1)[/tex]
m is the slope and x₁ and y₁ is an ordered pair.
Thus, let m be 3, y₁ be 5, and x₁ be 2. Thus:
[tex]y-5=3(x-2)[/tex]

Hii, so this was one of the questions on a previous CSAT exam (korean sat). I was curious and decided to look at a few questions. This question I found was particularly interesting and I am close to figuring it out but i keep getting stuck. Would anyone like to explain how this works and how to solve it?
Answer:
Step-by-step explanation:
Well you can calculate the area of the base side by the integration of cos - sin x over the limits x = 0 and x = π/6.
Then I think one side of the square would be cos π/6 - sin π/6.
So I think the required volume can be worked out as area of base * length of a side of the square.
I think that,s the way to do it, if i have interpreted the question correctly.
The question I have is y=3bx-7x. It says to solve the literal equation for x.
Answer:
y/( 3b-7)=x
Step-by-step explanation:
y=3bx-7x
Factor out x
y=(3b-7)x
Divide each side by (3b-7)
y/( 3b-7)=(3b-7)x/ ( 3b-7)
y/( 3b-7)=x
Answer:
[tex]\huge \boxed{x= \frac{y}{3b-7} }[/tex]
Step-by-step explanation:
[tex]\sf y=3bx-7x[/tex]
Factor out x from the expression.
[tex]\sf y=x(3b-7)[/tex]
Divide both sides by (3b - 7).
[tex]\sf \displaystyle \frac{y}{3b-7} =x[/tex]
