helpp. Pleasee need answerr
Answer:
This probaly sounds a little confusing
Step-by-step explanation:
1 day = 10 laps
1 lap = 400 meters
1 km = 1000 meters
12 km = ? days
We can use this information to find out a lot that we don't know.
HOW MANY METERS PER DAY??
In order to find the number of meters in a day, we think, "She ran 400 meters 10 times... 400 times 10... that's 4000 meters in one day."
1 day = 4000 meters (10 x 400 meters)
HOW MANY KILOMETERS PER DAY?
In order to find the number of km in a day, we can think, "One thousand is a kilo. There are 4 'one thousand's in 4000. Kali ran 4 kilometers (literally 4 thousand meters) per day.
1 day = 4 km (4000 m / 1000)
From here you can solve simply by thinking "How many 4km does it take to get to 12km?"
4 x ? = 12
? = 12 / 4
? = 3

When you roll 2 die, what is the probability of the event: Two numbers are odd and the sum is less than 5.
==========================================================
Explanation:
Let's use (x,y) notation to denote the results of the two dice. So x is the first dice value and y is the second. Something like (2,1) means we rolled a '2' on the first die, and a '1' on the second die. The order matters.
We want both x and y to be odd, and we also want x+y < 5.
Here are all of the ways to fit those conditions:
(1,1)(1,3)(3,1)There are 3 ways to achieve this goal out of 6*6 = 36 ways to roll two dice without any restriction. The probability we're aiming for is 3/36 = 1/12
Side note: 1/12 = 0.0833 = 8.33% approximately.

On a unit test in a statistics class, the teacher determines that the mean test grade was 77.5 with a standard deviation of 5.2. One student’s test grade was 91. What is the z-score for the student’s test?
–5.20
–2.60
2.60
5.20
Answer:
2.60
Step-by-step explanation:
z-score is the difference between the score and mean, divided by the standard deviation.
[tex]z = \frac{x - \mu}{\sigma}[/tex]
[tex]z = \frac{91-77.5}{5.2} = \frac{13.5}{5.2} \approx 2.596[/tex]
So 2.6 is an answer close enough.

Answer:
see explanation
Step-by-step explanation:
(a)
The area is calculated as length × breadth
area = 2x(2x + 6) ← distribute
= 4x² + 12x
(b)
area = x(x + 4) ← distribute
= x² + 4x
(c)
shaded area = 4x² + 12x - (x² + 4x)
= 4x² + 12x - x² - 4x ← collect like terms
= 3x² + 8x
Please help, Describe two methods that can be used to find the area of the composite figure.
Area of the composite figure can be find by using additive areas method and subtractive areas method
What is Composite figure?Composite geometric figures are made from two or more geometric figures. The composite figure below is made from parts of a rectangle and a circle
Since, Area is the quantity that expresses the extent of a region on the plane or on a curved surface.
Area of the composite figure can be find by using two methods,
Additive areas method and Subtractive areas method
In Addictive areas method
Break the composite shape into basic shapes
Find the area of the each basic shapes
Add all the areas of basic shapes together
In Subtractive areas method
Break the composite shape into basic shapes. That shape maybe larger than the composite shapes.
Find the area of the each basic shapes
Area of the composite shape will be the difference between the area of the larger shape.
Hence, the area of the composite figure can be find by using additive areas method and subtractive areas method

Can anyone help me with #1 and #2 and #7 and #8 please I will mark brainlist!!!
Step-by-step explanation:
For #7 and #8, they have given you the answer of the product but without decimals.
You can just add up all the decimal places for this kind of multiplication.
For example, 6.543 and 2.6 have 4 decimal places in total (underlined), so just count four: 17.0118.

The temperature was 48°F and dropped 15° in two hours.
What was the temperature after the change?
Answer:
33 degrees Fahrenheit.
Step-by-step explanation:
If the temperature was 48 degrees, and it dropped 15, that means the initial temperature was subtracted by 15.
48 - 15 = 33.
Answer:
33°F
Step-by-step explanation:
The initial temperature was 48°F. Then, it dropped by 15°.
I am assuming that both values are given in the same unit.
48 - 15 = 33
The temperature should be 33 degrees now.
Hope this helps.

43.5% of this skeleton's body is his mermaid tail.
Write the percent as a decimal.
Type a number
Complete the table for the given rule.
Rule: y = 52
~Answer~
Substitute your numbers:
y = 5x
For the first one, y equals 5, so substitute 5 for y.
So, 5 = 5x.
What multiplied by 5 gives 5? The answer is 1.
So, the first one is 1.
Do the same for all the others.
So, 4 = 5x.
4 = 5(4/5)
As a decimal that equals 0.8.
For the last one, I can't tell if that is saying 2 or .2 so I'll do both.
for 2, you will do 2 = 5x and for .2, you will do .2 or 0.2 = 5x.
For 2, it would be 2/5 or 0.4.
For .2 or 0.2, it would be 0.04.
So,
x y
1 5
4/5 or 0.8 4
0.4 if it is 2 and 0.04 if it is 0.2. 2
(looking back, I'm pretty sure it was just 2 and not .2)
I hope this is what u were looking for, if not I'm so sorry for a useless answer. I wasn't completely sure whether I was doing it right since I haven't done these types of math problems in some time.

Philip has a box of crayons. 45 are yellow, 12 are green, 25 are blue, and 8
are red. If Philip selects a crayon at random, what is the probability of not
picking a green? *
a. 1/2
b. 5/18
c. 2/15
d. 13/15
Answer:
option d
Step-by-step explanation:
First we find the probability of getting green, then we can subtract the result from 1 to find the probability of not getting the green crayon
P( green )
[tex]\frac{12}{45+12+25+8} \\= \frac{2}{15}[/tex]
P '(green) = 1 - 2/15
= 13/15

The volume of a sphere can be calculated by V = 4/3 * pi If the volume is 113.04 cm ^ 3 what is the radius?
Answer:
2.99 cm
Step-by-step explanation:
V= [tex]\frac{4}{3}[/tex](pi)(r^3)=113.04cm^3
113.04/ [tex]\frac{4}{3}[/tex](pi) = r^3 = 26.99
r=[tex]\sqrt[3]{26.99}[/tex] = 2.99cm
