Answer is 3 m/s.
Step-by-step explanation:-The ostrich ran at a constant velocity, so it's velocity was :
[tex]velocity = \frac{distance}{time} [/tex]
It is said that the bird ran for 160 seconds and it made it half-way to its nest, so the distance was :
[tex]distance = \frac{960 \: metres}{time} [/tex]
[tex]distance = 480 \: metres[/tex]
And the velocity is :-
[tex]velocity = \frac{480 \: metres}{160 \: seconds} [/tex]
[tex]velocity = 3 \: m/s[/tex]
Therefore, the ostrich ran at a velocity of 3 m/s .
Simplify the expression.

please help me with this!!! i’m begging!
Answer:
Domain is 3 <x>_-2
Range is 6 <x>_-3 (the lines are supposed to be under the >. it means equal to)
Step-by-step explanation:
First look on the x-axis, is goes from 3 to -2. now look at the colored in dot. that means more than or equal to. So the sign of -2 is x >_ -2. put the 3 on the other side. It stops at three so the sign is > 3. so 3<x>_ -2
Do the same with the y-axis except look up and down instead of left and right. so the numbers are 6 and -3. Use the same method above. this is set builder notation.
X/2 -5=20 please give details
Answer: x=50
how?
[tex]\frac{x}{2}[/tex] - 5= 20 (first ADD 5 with 20 whatever you do on one side you have to do it to the other) so that gives us:
[tex]\frac{x}{2}[/tex]=25 (we see that 2 is being divided by x and we want X alone so the inverse of division is MULTIPLICATION)
25 x 2= 50
therefor the x=50

Answer:
-1
Step-by-step explanation:
Let's take two points on the line- (0,2) and (2,0).
To find the slope:
[tex]m = \frac{y_2 - y_1}{x_2-x_1}\\m = \frac{0 - 2}{2-0}\\m = \frac{-2}{2}\\m = -1[/tex]
The slope is -1.

what's the measure of <4?
Answer:
The angles of a triangle all add up to 190º, so the answer would be 63º
Step-by-step explanation:
The bottom angle is a right angle; 90º
The top left angle is 37º
So the top right angle must be 63º

how do you find the coefficient on a scatterplot?
Answer:
The correlation coefficient is determined by dividing the covariance by the product of the two variables' standard deviations. Standard deviation is a measure of the dispersion of data from its average. Covariance is a measure of how two variables change together.
Find the x- and y-intercepts of the graph of — 7x + 8y = 40. State your answers as
whole numbers or as improper fractions in simplest form.
Answer:
x-intercept is (40/7, 0) and y-intercept is (0, 5)
Step-by-step explanation:
x-intercept ==> y-coordinate is 0 ==> y=0
y-intercept ==> x-coordinate is 0 ==> x=0
because the function is 7x + 8y = 40
when y = 0 ==> 7x = 40 ==> x = 40/7
so the x-intercept is (40/7, 0)
when x = 0 ==> 8y = 40 ==> y = 5
so the y-intercept is (0,5)
How do I solve this?
Answer: 2l+2w=48
Subtract 2w from both sides.
2l=48−2w
Divide both sides by 2.

2l
=

48−2w
Dividing by 2 undoes the multiplication by 2.
l=
2
48−2w
Divide 48−2w by 2.
l=24−w
Answer:
14centimeters
Step-by-step explanation:
from our equation,
2l + 2w = 48
we know that the width = 10cm
so,
2l + 2( 10 ) = 48
2l + 20 = 48
2l = 48 - 20
2l = 28
divide through by 2
2l / 2 = 28 / 2
l = 14
therefore,
l = 14 centimeters

BRAINLIEST PLEASE !!
Answer:
Step 1: Subtract 3 from both sides of the inequality.
Step 2: Add 8x to both sides
Step 3: Divide both sides of the inequality by the coefficient of x.

On a farm there are dogs and chickens. There are a total of 17 animals and 48 legs. How many chickens and dogs are on the farm
Answer:
7 dogs and 10 chickens
Step-by-step explanation:
dogs have 4 legs, chickens have 2 legs. 7 dogs which would be 28 legs and 10 chickens which would be 20 legs adds up to 48 legs
What is the slope of the line represented by the equation y =4/3x-3
Answer:
m, is equal to (4/3)
Step-by-step explanation:
Match the given equation y =(4/3)x-3 to the standard slope-intercept form y = mx + b. By doing so we see that the slope, m, is equal to (4/3).

Question 7 = 2 Points
Oct 06, 8:37:22 PM
Samantha has $600 to spend at a bicycle store for some new gear and biking outfits.
Assume all prices listed include tax,
• She buys a new bicycle for $399,95
• She buys 3 bicycle reflectors for $7.01 each and a pair of bike gloves for $34.06.
• She plans to spend some or all of the money she has left to buy new bilding outfits
for $75,88 each
Write and solve an inequality which can be used to determine w, the number of
outfits Samantha can purchase while staying within her budget
Answer:
See belowStep-by-step explanation:
The budget is $600.
Samantha spends the following amount:
399.95 + 3*7.01 + 34.06 = 455.04Now, she plans to buy w outfits which cost $75.88 each.
The inequality for this is:
455.04 + 75.88w ≤ 600Solving this we get:
75.88w ≤ 600 - 455.0475.88w ≤ 144.96w ≤ 144.96 / 75.88w ≤ 1.91w = 1 is the only integer solution greater than zero

If I roll 2 dice, what is the
probability that their total is a
prime number?
Answer:
The logic is there are six sides to each die, so for each number on one die you can pair with six different numbers on the other die. Therefore, the probability of rolling a prime number on two dice is 15/36, which reduces to 5/12
What is 7^5 equal to
plz help with 10-11 if you don’t mind
Properties used:
All angles of a triangle add up to 180 degrees
180 is a straight line; so both sides of a straight line add up to 180
10) 180 - 153 = 27
180-27-133 = ?
? = 20 degrees
11) 180-87=93
180-93-23=?
? = 64 degrees
Answer:
11.) Angle FED = 20 Degrees | 12.) Angle FHG=74
Step-by-step explanation:
11.) Angle FED= 20 degrees
one side of a straight line = 180 degrees
all the angles of the insides of a triangle added together = 180 degrees
If angle EDF is 153 degrees, we do 180 - 153 = 27 degrees. Now we know that angle FDE = 27 degrees. Now we add all the angles we have together. 133+?+27=180. (133+27=160) If 160+?=180, we solve it by doing: 180-160, and we get 20.
12.) Angle FHG=74
For this problem, we use the same formulas as before. So let's solve!
180-87=93. So angle GFH=83 degrees.
Now we need to add the angles together:
83+23+?=180. 83+23=106
180-106=74.

Answer:

Step by Step Explanation:
The sum of three numbers is 66. The second number is twice the first and six less than the third. find the numbers
Step-by-step explanation:
let the 1st number be x
and,
2nd number = 2x
3rd number = 2x + 6
their sum = 66
so, after inserting the values we got
→ x + 2x + 2x + 6 = 66
→ 5x + 6 = 66
→ 5x = 66 - 6 = 60
→ x = 60/5 = 12
→ x = 12
therefore,
1st number = x = 12
2nd number = 2x = 12 × 2 = 24
3rd number = 2x + 6 = 24 + 6 = 30
hope this answer helps you dear...take care and may u have a great day ahead!

Original price: $12
Mark-up: 45%
What is the selling price?
Answer:
The selling price is $17.40
Step-by-step explanation:
x = selling price
x = 12 + 0.45(12)
x = 12 + 5.4
x = 17.4
The final selling price is $17.40.
Percentages are percents of a whole. This means that 45% = 0.45. You can use this to your advangage when solving these types of equations.
Answer:
$17.40
Step-by-step explanation
Find what 45% of 12 is.
You can do this by multiplying 0.45 by 12 which is 5.4
Then you just add 5.4 to 12 which gives you 17.4

Answer: [tex]\sqrt{11[/tex]
Step-by-step explanation: pythagorean theorem a^2 + b^2 =c^2
switch it to c^2 - b^2 = a^2
c=6 and b=5
(6)^2 - (5)^2 = 36-25 which is 11
11=c^2. to find c, square root 11. the simplest form for this is just [tex]\sqrt{11[/tex]
