Answer:
It is 5 seconds option C
Step-by-step explanation:
When the ball would hit the ground, h would reduce 0.
We can equate the R.H.S to 0.
∴ 0= -16t²+64t+80
0 = t² - 4t - 5 (dividing both sides by -16)
0 = t²+t - 5t -5 (by splitting the middle term)
0 = t ( t+1) -5 (t+1)
0= (t-5) * (t + 1)
when t-5=0 ; when t+1=0
t =5 ; t= -1 time cannot be -ve
∴ t= 5 seconds
Hope this helps you.
Answer:
C) 5 seconds
Step-by-step explanation:
Given equation:
[tex]h=-16t^2+64t+80[/tex]
where:
h = height of a ball above the ground (in feet).t = time (in seconds).The ball hits the ground when the height is zero.
Therefore, substitute h = 0 into the given equation and solve for t.
[tex]\begin{aligned}\implies -16t^2+64t+80 & = 0\\-16(t^2-4t-5) & = 0\\t^2-4t-5 & = 0\\t^2-5t+t-5&=0\\t(t-5)+1(t-5)&=0\\(t+1)(t-5)&=0\\\end{aligned}[/tex]
Apply the zero-product property:
[tex]\implies t+1=0 \implies t=-1[/tex]
[tex]\implies t-5=0 \implies t=5[/tex]
As time cannot be negative, t = 5 only.
Therefore, it takes 5 seconds for the ball to hit the ground.

suppose river has new treats that are 10 calories each. how many of the new treats can she have and remain in her calorie range?
She can have at least 3 and at most 6 dog treats in a day
River can have - n = 10/y number of treats to remain in her calorie range, where the calorie range is [y] calories.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
We have the following problem -
River has new treats that are 10 calories each. how many of the new treats can she have and remain in her calorie range.
Assume the calorie range to be [y] calories and assume she can have [n] number of treats. We can write the linear function as -
10n = y
OR
y = 10n
This this the equation of the straight line. She can have -
n = 10/y
number of treats to remain in her calorie range.
Therefore, River can have - n = 10/y number of treats to remain in her calorie range.

make q the subject of the formula 5(q+p)/2 = 3 + 4p
Answer:
q = [tex]\frac{6+3p}{5}[/tex]
Step-by-step explanation:
[tex]\frac{5(q+p)}{2}[/tex] = 3 + 4p ( multiply through by 2 to clear the fraction )
5(p + q) = 6 + 8p ← distribute parenthesis on left side )
5p + 5q = 6 + 8p ( subtract 5p from both sides )
5q = 6 + 3p ( divide both sides by 5 )
q = [tex]\frac{6+3p}{5}[/tex]
A large rectangle is made up of nine identical rectangles whose longer side equals 10. What is the area of the large rectangle?
==========================================================
Explanation:
Refer to the diagram below.
A small rectangle has its longer side equal to 10 and its shorter side is x, which is some real number on the interval 0 < x < 10.
Across the top, the two sides of length 10 add to 20. So the larger rectangle has a horizontal dimension of 20 units.
The vertical side of the larger rectangle is x+10+x = 2x+10 units
The area would be
area = length*width = 20(2x+10) = 40x+200
Each of the nine smaller rectangles has area of length*width = 10x. Since we have 9 identical copies, the smaller rectangle areas must add to 9*10x = 90x
---------------
Equate those two expressions and solve for x
90x = 40x+200
90x-40x = 200
50x = 200
x = 200/50
x = 4
So each smaller rectangle has area of 10*x = 10*4 = 40 square units. In total, the nine smaller rectangles combine to an area of 9*40 = 360 square units
Note how x = 4 leads 40x+200 to result in 360 as well.

Answer:
n = 3.16 units; p = 5 units
Step-by-step explanation:
to find the length of the lines you need to use the pythagorean theorem or a^2 + b^2 = c^2
in this case a is x, b is y, and c is the length
so for n it is:
1^2 + 3^2 = c^2 -->
1 + 9 = c^2 -->
10 = c^2
c = 3.16227766 or about 3.16 (this is n's length)
for p it is:
3^2 + 4^2 = c^2 -->
9 + 16 = c^2 -->
25 = c^2 -->
c = 5 (this is p's length)

Ox= 14, y= 11
Ox=14, y = 12
Ox= 15, y= 11
Answer:
x=15,y=12
Step-by-step explanation:
Alternate angles are those angles that are on the opposite side of the parallel lines transverse with a line touching both parallel lines.
The value of x and y are 15 and 12.
x = 15
y = 12
Option A is the correct answer.
What are corresponding angles?The angles that are in the same position on two parallel lines intersected by a transversal line on the parallel lines.
Corresponding angles are equal.
We have,
The figure contains four angles.
62 and (4x + 2) are alternate angles.
12y and 144 are alternate angles.
We know that alternate angles are equal.
So,
62 = 4x + 2 ____(1)
12y = 144 _____(2)
From (1) we get,
62 = 4x + 2
Subtract 2 on both sides.
62 - 2 = 4x + 2 - 2
60 = 4x
Divide both sides by 4.
4x = 60
x = 60/4
x = 15
From (2)
12y = 144
Divide both sides by 12.
y = 144/12
y = 12
Thus,
The value of x and y are 15 and 12.
x = 15
y = 12
Option A is the correct answer.

The circle graph shows the results of a survey. Of those surveyed, 80 said yes. About how many people were surveyed?
Answer:
134 people
Step-by-step explanation:
80 / .6 = 133.333
Answer:
134 people
Step-by-step explanation:
we can use cross multiplication to solve this problem:
we know that 60% is 80 people and 40% is x people (we put x because we don't know the exact number of how many people yet)
now we set it up:
[tex]\frac{80}{60}[/tex] = [tex]\frac{x}{40}[/tex]
= 60x = 3200
= x = 53.33333
now we add the two numbers of people up:
53.33333 + 80 = 133.3333
since it is a decimal, it would be safer to assume that there are 134 people

Today only, a desk is being sold at a 33% discount. The sale price is $603.
What was the price yesterday?
The original price of the desk before discount was $900.
What is discount?A discount is the reduction in the marked price of items, discounts are generally given to customers to attract them towards some items or on sale.
Given that a desk is at sell today, the shop is offering 33% discount on it, which will give a selling price of $603.
We need to find the desk's yesterday price,
So, let the yesterday price be x,
Therefore,
100 - 33 = 67
Therefore,
67% of x = 603
x = 603 × 100 / 67
x = 900
Hence the original price of the desk before discount was $900.
