Answer:
The answer would be 180 meters.
Step-by-step explanation:
We are told the runner runs at 9 m/s for 20 seconds.
Since they run 9 meters per second, all we have to do is multiply 9 by 20, which will give us 180 meters.
9 x 20 = 180

Logan is 2 years older than Lindsey. Five years ago, the sum of their ages was 30. Find Lindsey’s
current age.
Answer:
lindsey = x = 19
logan = x + 2 = 21
Step-by-step explanation:
lindsey =x
logan = x + 2
-------
5 yrs back
lindsey = x - 5
logan = x + 2 - 5 = x - 3
~~~~~~~~~~
x- 5 + x - 3 = 30
x + x - = 30 +5 +3
2x = 38
x = 38/ 2 = 19

Need to find measure of m, p
Step-by-step explanation:
2p-5=p+5
p=10°
2m=10
m=5
Answer:
m = 5
p = 10
Step-by-step explanation:
In triangle HIJ,
IH = IJ.. (given)
Therefore,
2m = 10
m = 10/2
m = 5
IK is angle bisector of triangle HIJ.
So,
(2p - 5)° = (p = 5)°
2p - 5 = p + 5
2p - p = 5 + 5
p = 10

for every 5 red cars there are 8 black cars. If there are 24 more black cars than red cars how many total vehicles are there
Answer:
15 red cars + 24 black cars = 38
The total vehicles are 104.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
For every 5 red cars there are 8 black cars.
And, There are 24 more black cars than red cars.
Here, For every 5 red cars there are 8 black cars.
Hence, Number of red cars = 5x
Then, Number of red cars = 8x
And, There are 24 more black cars than red cars.
Hence, We get;
⇒ 24 + 5x = 8x
Solve for x as;
⇒ 24 = 8x - 5x
⇒ 24 = 3x
⇒ x = 8
Thus, Number of total vehicles = 5x + 8x
= 5×8 + 8×8
= 40 + 64
= 104

Simplify cot θ sec θ.
Answer:
csc θ
Step-by-step explanation:
cot θ sec θ can be substituted by reducing the expression into equivalent parts.
cot θ = (cos θ)/(sin θ)
sec θ = 1/(cos θ)
Reduce these two values to get 1/(sin θ)
This expression can then be changed to csc θ, as it is also equivalent.
The trigonometric expression cot θ × sec θ in the simplified form will be cosec θ.
What is trigonometry?Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The expression is given below.
⇒ cot θ × sec θ
We know that cot θ = cos θ / sin θ and sec θ = 1 / cos θ, then we have
⇒ cot θ × sec θ
⇒ cos θ / sin θ × 1 / cos θ
⇒ 1 / sin θ
We know that 1 / sin θ = cos θ
⇒ 1 / sin θ
⇒ cosec θ
The trigonometric expression cot θ × sec θ in the simplified form will be cosec θ.

What is division?Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.
here, we have,
given that,
the expression is:
5n = 60
now, we have to find the value of n
so, we have to simplify this,
we have,
5n = 60
now, dividing both side by 5,
we get,
5n/5 = 60/5
or, n = 60/5
or, n = 12

A quadratic equation has a
discriminant equal to 5. What
does this tell you about the
solution(s) to the equation?
Answer:
[tex]\boxed {\boxed {\sf 2 \ real \ solutions }}[/tex]
Step-by-step explanation:
The quadratic formula is:
[tex]{x = \frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}}[/tex]
The discriminant of a quadratic is just the expression under the square root, or [tex]b^2-4ac[/tex]. This can tell us the number of solutions a quadratic has.
If the discriminant is:
Positive = 2 real solutions Equal to Zero = 1 real double/repeated solution Negative = 0 real solutions, but 2 imaginary solutionsOur quadratic equation has a discriminant of 5, which is positive. Therefore, it has 2 real solutions.

We move all terms to the left:
5x+6+6x-25-(180)=0
We add all the numbers together, and all the variables
11x-199=0
We move all terms containing x to the left, all other terms to the right
11x=199
x=199/11
x=18+1/11
