10 laps around track each day. Each lap around the track is 400 meters. How many day will take kali to run a total 12 kilometers
Answer:
3 days
Step-by-step explanation:
First, let's convert 400 meters to km (kilometers):
To find km from m we divide the meters by 1000:
400/1000 = 0.4
Therefore, there are 0.4 km in 1 meter.
Kali runs 10 laps every day, since 1 lap is 0.4 km we can multiply 10 by 0.4 to see how many kilometers they run in 1 day:
(10)(0.4) = 4
Kali runs 4 kilometers every day
Now, we can find how long it will take Kali to run a total of 12 kilometers by dividing 12 by 4
12/4 = 3
It will take Kali 3 days to run a total of 12 kilometers.

How do flowers contribute to the survival of the plant?
A. They are needed to absorb water.
B. They are needed to make food.
C. They are needed for reproduction.
D. They are needed to create energy.
Answer: c
Step-by-step explanation:
A plant's ability to reproduce and contribute to the survival of its own species is assured when flowering occurs at the right point in time. If flowering starts too early, the result may be a poor crop of biomass as well as fruit.

The answer for number 1 is 1.72. The answer for number 2 is 4.83.
So for number one, the first thing you need to do is determine how many sides are on the first shape. Since it is a pentagon, and one pentagon has 5 sides, then you use the following formula to determine the volume of a[tex]V = \frac {1}{4} \times \sqrt{5 \times (5 +2 \times \sqrt {5})} \times (10)^{2} \times 10[/tex] pentagon: [tex]\alpha = \frac{1}{4} \times \sqrt[]{5(5+2 \sqrt[]{5}) \alpha ^{2} }[/tex] And in this case, the area would be 1.72, because if you insert the side lengths, the equation would look like this: [tex]V = \frac {1}{4} \times \sqrt{5 \times (5 +2 \times \sqrt {5})} \times (10)^{2} \times 10[/tex] , which if you solve this equation, then you will end up with the answer of 1.72.
For number two, the first thing you need to do is determine how many sides are on the second shape. Since it is an octagon, and the prefix oct means 8, the number of sides on the shape is 8. If the perimeter is 64, and there are 8 sides, you can divide 64 by 8 to get 8. The equation to solve for the area should look like this: [tex]V = 2(1 + \sqrt{2}) \times s^{2} \times h[/tex]. Now all you need to do is insert the side lengths to the proper places. It should then look like this: [tex]V = 2(1 + \sqrt{2}) \times 8^{2} \times 8[/tex], after you solve the equation, you should end up with 4.83.
Please help me with this question please help me I beg you
Step-by-step explanation:
Given
f(x) = 5 / 2x - 1
f^-1( x) = ?
Let
y = f(x)
y = 5/2x - 1
Interchanging the roles of x and y we get
x = 5/2y - 1
2y - 1 = 5/x
2y = 5/x - 1
y = (5/x - 1)/ 2
f^-1(x) = ( 5/x - 1) / 2

Find the first 3 terms of arithmetic sequence if t5=-154 and t9=-274. find t1, t2, t3
Answer: t1 = -34; t2 = -64; t3 = -94
d is the distance between numbers (d > 0)
we have:
t5 = t1 + 4d = -154
t9 = t1 + 8d = -274
we have the equations:
t1 + 4d = -154
t1 + 8d = -274
<=> t1 = -34
d = -30
with t1 = -34 and = -30 => t2 = -34 - 30 = -64
t3 = -64 - 30 = -94

Would the three squares below join together to make a right triangle? Why or why not? picture shows squares
Answer:
Yes.
The first has an area of 9, so each side is three.
The second has an area of 16, so each side is four.
Each side of the third square is given as 5.
So the triangle has sides of 3, 4, and 5.
3²+4²=5²
9+16=25
25=25 It works given the Pythagorean theorem.
Step-by-step explanation:
Yes.
The first has an area of 9, so each side is three.
The second has an area of 16, so each side is four.
Each side of the third square is given as 5.
So the triangle has sides of 3, 4, and 5.
3²+4²=5²
9+16=25
25=25 It works given the Pythagorean theorem.

ABCD is a square and triangle DEF is equilateral. Triangle ADE is isosceles with AD=AE calculate size of angle AEF
Answer:
∠AEF = 90°
Step-by-step explanation:
The size of angle AEF is given below:
Given that
ABCD is Square
CDF is a straight line
∠ADF = 90°
And triangle DEF is an Equilateral Triangle
So,
∠FDE = 60°
Now
∠ADE = 90° - 60°
= 30°
AD = AE
∠AED = 30°
∠DEF = 60° because of an equilateral triangle
Now
∠AEF = ∠AED + ∠DEF
∠AEF = 30° + 60°
∠AEF = 90°

During the first week of winter, a business used 1/6 of a tank of heating oil. It used two times as much oil in the second week as it did in the first week. It used another 1/8 of a tank during the third week. A delivery of ½ tank was made at the end of the third week. The final fuel gauge shows a line between ½ and F. How much fuel did the business start with?
Answer:
The business started with 23/24 of their tank full
Step-by-step explanation:
Step 1.
Find the LCM of the denominators (2,6 and 8)
=24
Step 2.
Change all the fractions to have a denominator of 24
1/6=4/24
1/8=3/24
1/2=12/24
3/4= 18/24
Step 3.
Work backwards
18/24-12/24
=6/24+3/24
=9/24+(2×4/24)
=17/24+6/24
=23/24

answer and explanation are in the picture.
make a graph on f(x)=−3/2(x+1)(x−5)
Answer:
explanation below
Step-by-step explanation:
f(x) = −3/2(x+1)(x−5) = -3/2 (x²-4x-5) = -3/2 (x²-4x+4-9) = -3/2 ((x-2)² - 9)
f(x) = -3/2 (x-2)² + (-3/2)*(-9) = -3/2 (x-2)² + 13.5
There are points to be referenced for the graph:

Dominic is going to attend a baseball game on Saturday afternoon. He has a total of $40 he can spend. The ticket cost is $22, and the parking cost is $7. He intends to spend his remaining money on team window decals that cost $4.50 each. What is the greatest number of decals Dominic can buy? A 2 decals B 3 decals C 4 decals D 5 decals
Answer: A. 2 Decals
Step-by-step explanation: time4learning
The requried Dominic can buy a maximum of 2 decals.
What is simplification?Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve.
Dominic has $40 to spend, and he will spend $22 for the ticket and $7 for the parking. So, he will have:
$40 - $22 - $7 = $11
left to spend on team window decals.
Each decal costs $4.50, so we can divide the amount Dominic has left by the cost of each decal to find the maximum number of decals he can buy:
$11 ÷ $4.50 ≈ 2.44
Since we can't buy a fraction of a decal, we need to round down to the nearest whole number. So, Dominic can buy a maximum of 2 decals.
Therefore, the answer is A, 2 decals.
