Jillian calculates that see will take 95 minutes to run 7 miles. She runs the distance in 80 minutes. What is Jillian’s percent error?
Answers
Answer:
Kawaii, the problem is the comparison with the calculated time for Jillian and the actual time for Jillian to run the 7 miles.
%error=(calculated value - experiemental value)/calculated * 100%
%error=(95-80)/95*100%=15/95 *100% = 15.79 ≈ 16% error
Note: 16% error is the approximate error because the numbers have 2 significant figures stated in the problem.

Write the following as an inequality.
- 2 is less than w, and 6 is greater than or equal to w
Use w only once in your inequality.
Answers
Answer:
-2 < w ≤ 6
Step-by-step explanation:
The inequalities you're asked to combine are ...
-2 < w
6 ≥ w
Turn one of these around so the "arrows" point in the same direction. (My preference is that they point to the left.) Now you have ...
-2 < w
w ≤ 6
You combine these by putting w in the middle:
-2 < w ≤ 6
_____
Alternate solution
I like the above solution because it puts the components of the expression in the same (left-right) order as they appear on a number line. However, both inequalities can be turned around to get ...
6 ≥ w > -2

Which geometry includes a triangle that has angle measures of 45°, 61°, and 70°? Euclidean geometry hyperbolic geometry elliptical geometry spherical geometry
Answers
Answer: Hyperbolic geometry
Step-by-step explanation:
Hyperbolic triangle is a non - Euclidean triangle in which the sum of the angles of the triangle is not up to 180 degrees. That is, less than 180 degree.
Euclidean geometry is the normal geometry that is being taught in school in which the sum of the angles of its triangle equals 180 degrees
While spherical geometry is a non euclidean geometry with sum of the angles of its triangle greater than 180 degrees.
Therefore, the triangle that has angle measures of 45°, 61°, and 70° is a non - Euclidean geometry which is hyperbolic geometry.
Answer:

Step-by-step explanation:
We can simply add the exponents together because they have the same base which will give us a^(2 + m).
Answer:
a^[2+m]
Step-by-step explanation:
When multiplying two polynomials with the same base but different exponents, we add the exponents because
a^m*a^n
= a^m+n
So,
a^2*a^m

A small staircase is made so that the horizontal piece of each step 10 inches long and 25 inches wide. Each step is 5 inches above the previous one. What is the surface area of this staircase?
Answers
Answer:
1125 in²
Step-by-step explanatio1D
Assume that the staircase is three steps high, as in the diagram.
Each tread has a surface area of
10 in × 25 in = 250 in²
Each riser has a surface area of
5 in × 25 in = 125 in²
There are three treads and three risers, so the total surface area is
3 × 250 in² + 3 × 125 in² = 750 in² + 375 in² = 1125 in²
The surface area of the small staircase which is made such that the horizontal piece of each step 10 inches long and 25 inches wide is 1125 in².
What is surface area?Surface area of any solid or the 3 dimensional body is the area of each faces by which the solid body is enclosed. Surface area of a cuboid is the sum of total area of each face.
The image of the staircase is shown below. This small staircase is made so that the horizontal piece of each step 10 inches long and 25 inches wide.
Thus, the surface area of the trade of stair case is,
[tex]A_{t}=10\times25\\A_{t}=250\rm\;in^2[/tex]
Each step is 5 inches above the previous one. Thus, the surface area of the riser of stair case is,
[tex]A_{r}=25\times5\\A_{r}=125\rm\;in^2[/tex]
Total surface area of one step is,
[tex]A_{s}=3(A_{t}+A_{r})A_{s}=3(250+125)\\A_{s}=3(375)\\A_{s}=1125\rm\;in^2[/tex]
Hence, the surface area of the small staircase which is made such that the horizontal piece of each step 10 inches long and 25 inches wide is 1125 in².

Can someone help me for brainllest ITS TIMED AND IM FREAKING OUT
Answers
Answer:
1.
If two angles are supplementary, their sum is 180 degrees.
Check: 10 + 170 = 180
=> Maryam's claim is correct
If two angles are complementary, their sum is 90 degrees.
Check: 81 + 9 = 90
=> Ailia's claim is correct
2.
As the definition:
Vertical angles have sides that form two pairs of opposite rays.
Adjacent angles have a common side and don't overlap.
=> As provided pair of angles, they are adjacent pair of angles.
=> Ahmed's statement is wrong, Saalem's statement is correct.
