Age If you add Natalie's age and Fred's age, the result is 43. If you add Fred's age to 4 times
Natalie's age, the result is 79. Write and solve a system of equations to find how old Fred and
Natalie are.
Fred is
years old. Natalie is
years old.
Answers
So,
A/Q
X + Y = 43. Let it be eqution 1
and
X + 4Y = 79. Let it be equation 2
Combining equation 1 and 2, we get
( X + Y) + 3Y = 79
43 + 3Y = 79
3Y = 36
Y = 12
Now, evaluating the value of Y in equation 1 we get,
X + 12 = 43
X = 31
Therefore, Fred is 31years old and Natalie is 12 years old.
Which runs faster: a cheetah that can run 60 feet in 6 seconds or a gazelle that can run 100 feet in 10 seconds?
They run at the same speed.
A gazelle runs faster.
A cheetah runs faster.
Answers
Answer:
They run at the same speed
Step-by-step explanation:
First, you have to find a way seeing how fast both animals run in the same amount of time. You can find out how fast they both run in one second.
60 feet in 6 seconds is how many feet in one second? Well, you can do 60/6 (60 divided by 6) and you will see that in one second, the cheetah can run 10 feet
100 feet in 10 seconds is how many feet in one second? Same thing, you can do 100/10 (100 divided by 10) and you will see that the gazelle can run 10 feet in one second.
Finally, you compare the two answers from the two animals. For the cheetah, we learned that it can run 10 feet in one second, and for the gazelle, we learned that it can run 10 feet in one second. So, we know that they run at the same speed.
Thank you! Please let me know if this was helpful!
Answer:
Cheeta's speed = 10 feet per second
Gazelle's speed = 10 feet per second
Hence, They run at the same speed.
Step-by-step explanation:
Determining the Cheeta's speed:
Covered distance = 60 feet
Time taken = 6 seconds
Speed = Covered distance / Time taken
= 60 / 6
= 10 feet per second
Therefore, Cheeta's speed is 10 feet per second.
Determining the Gazelle's speed:
Covered distance = 100 feet
Time taken = 10 seconds
Speed = Covered distance / Time taken
= 100 / 10
= 10 feet per second
Therefore, Gazelle's speed is 10 feet per second.
Conclusion:
Cheeta's speed = 10 feet per second
Gazelle's speed = 10 feet per second
Hence, They run at the same speed.

What is dilation of triangle?Dilation of triangle means each point is stretched outwards or inwards from the center point by multiplying by the scale factor to form a similar triangle.
We have,
Triangle [tex]T V W[/tex] which has points [tex](- 4, 8)[/tex], [tex](0, 4)[/tex], and [tex](4, 4)[/tex] on a coordinate plane.
Scale factor [tex]\frac{3}{4} x, \ \frac{3}{4} y[/tex]
It has to be dilated to create a new triangle [tex]T'V'W'[/tex] .
So,
To create a new triangle [tex]T'V'W'[/tex] we have to multiply the original triangle's coordinate by scale factor, to get new triangle's coordinate .
So, we have to dilate the coordinates by [tex]\frac{3}{4} x, \ \frac{3}{4} y[/tex] ,
[tex]T'=(- 4, 8)=\frac{3}{4} *(-)4, \frac{3}{4} *8= (-3,6)[/tex]
[tex]V'=(0, 4)=\frac{3}{4} *0, \frac{3}{4} *4=(0,1)[/tex]
[tex]W'=(4, 4)=\frac{3}{4} *4,\frac{3}{4} *4=(0,0)[/tex]
So, the coordinates of triangle [tex]T'V'W'[/tex] after dilation are [tex](-3,6), \ (0,1), \ (0,0)[/tex] . Hence we can say that the coordinates of the endpoints of the segment [tex]T'V'[/tex] are [tex](-3,6), \ (0,1).[/tex]

A cup of coffee contains 140 mg of caffeine. If caffeine leaves the body at 10% per hour, how long will it
take for half of the caffeine to be eliminated from one's body?
Answers
Answer: 5 hours
Step-by-step explanation:
If 10% of 140 is 14. And if 14 mg of caffeine is leaving per hour then it would take 10 hours to completely leave from ones body, but for half of it to leave it would take 5.
It takes 5 hours to eliminate half of the caffeine from one's body.
Given that, a cup of coffee contains 140 mg of caffeine.
What is the percentage?In mathematics, a percentage is a number or ratio expressed as a fraction of 100.
Now, 10% of 140
=0.1×140=14 mg
If 10% of 140 is 14 and if 14 mg of caffeine is leaving per hour then it would take 10 hours to completely leave from one's body, but for half of it to leave it would take 5 hours.
Therefore, it takes 5 hours to eliminate half of the caffeine from one's body.

Thank you :]
Answers
Answer:
A: E = 0.05t +56
B: $73.50
C: $60.05
Step-by-step explanation:
A) I'll just explain the equation in one go
Equation: E = 0.05t + 56
0.05 - This is meant to represent the 5% of tips
5% = 5/100
5/100 = 0.05
56 - This is a set value that has been established as a constant, thus it simply needs to be added to the 5%
B+C) Since we already have the equation set up, we just need to plug in the variable, t.
B) E = 0.05(350) + 56
= 17.5 + 56
= 73.50
C) E = 0.05(81) + 56
= 4.05 + 56
= 60.05

In the triangle above, the console of p degrees is 0.8 what is the sine of q degrees
Answers
Answer:
Step-by-step explanation:
[tex]cosp=(8/10)\\ \\ p=cos^{-1}(8/10)\\ \\ q=90-p\\ \\ q=90-cos^{-1}(8/10)\\ \\ sinq=sin(90-cos^{-1}(8/10)\\ \\ sinq=(8/10)[/tex]
In the triangle above, the console of p degrees is 0.8. So, the sine of angle q is 0.6.
It seems like there is a description of a triangle with angles p and q, where the console of angle p is 0.8. However, the term "console" is not familiar in the context of trigonometry. I assume you meant "cosine" instead of "console."
If that's the case, let's proceed with the assumption that cos(p) = 0.8.
The cosine of an angle is the ratio of the adjacent side to the hypotenuse in a right-angled triangle. To find the sine of angle q, we need to use the Pythagorean trigonometric identity:
sin²(q) + cos²(q) = 1
We already know that cos(p) = 0.8, and since the sum of angles in a triangle is 180 degrees, we can find q:
q = 180 - p
Now, let's calculate sin(q):
sin²(q) + cos²(q) = 1
sin²(q) + (0.8)² = 1
sin²(q) = 1 - 0.64
sin²(q) = 0.36
Now, take the square root of both sides to find sin(q):
sin(q) = √0.36
sin(q) = 0.6
So, the sine of angle q is 0.6.

Angle D = 360-128-126-54 = 52o
Step-by-step explanation: got it right on edge
Since the sum of the angles in a quadrilateral is 360 degrees then the angle D is 50 degrees.
What is a quadrilateral?A quadrilateral is a four sided figure. Examples of quadrilaterals include; square, parallelogram, rectangle, kite etc.
The sum of angles in a quadrilateral is 360 degree hence;
A + B + C + D = 360 (sum of angles in a quadrilateral)
128 + 126 + 54 + D = 360
D = 360 - ( 128 + 126 + 54)
