find z. explain please
Answer:
13
Step-by-step explanation:
You need to use pythagorean theorem (a^2 + b^2 = c^2). In this case 5 is a, 12 is b, and z is c. 5^2 + 12^2 = z^2, this ends up as 169 = z^2. Now you find the square root of 169 which is 13.
Step-by-step explanation:
Maybe it is root 5²time 12²=60
BRAINILIEST PLEASEHelp? 2/7 done! We got this! I tried myself and I got a decimal ♀️
Please help ????? Just the bottom question
Answer:
144
Step-by-step explanation:
We can see that every 2 boxes has 24 peaches in it. That means that every single box would have 12 in it. Then it is just simple multiplication from there. 12 * 12 = 144.
Hope that this helps!
A triangle has sides with lengths of 9 feet, 14 feet, and 15 feet. Is it a right triangle?
Answer:
No its not, because if you use the pythagorean theorem formula 9 and 14 will not equal 15. So it wouldn't make it a right triangle.

How do you write an equation of a line given (1, 2) and (3, 4) in a slope -intercept form
Answer:
y = x + 1
Step-by-step explanation:
find slope first:
(4-2) / (3-1) = 2/2 or 1
now find the y-intercept, or 'b' by using one of the two given points and the slope
2 = 1(1) + b
2 = 1 + b
1 = b
equation in slope-intercept form:
y = 1x + 1 or y = x + 1

Answer:
8
Step-by-step explanation:
Prove algebraically that the square of any number is always 1 more than a multiple of 8
Answer:
This is interesting but I don't think it's provable (unless it's just the square of odd numbers).
3² = 9, which is 1 more than a multiple of 8 (8)
4² = 16, which is not 1 more than a multiple of 8 (8)
5² = 25, which is 1 more than a multiple of 8 (24)
6² = 36, which is not 1 more than a multiple of 8 (32)
7² = 49, which is 1 more than a multiple of 8 (48)
8² = 64, which is not 1 more than a multiple of 8 (64)
9² = 81, which is 1 more than a multiple of 8 (80)
10² = 100, which is not 1 more than a multiple of 8 (96)

Does anybody know how to find the distance between 2 things using the pythagorean theorem?
Answer:
Yes
Step-by-step explanation:
The two objects are plotted at different points in graph and one gets the difference of points y coordinates (change in y) and change in x too.
Then one can look for distance as hypotenous and change in y as height and change in x as the base of our imaginery triangle.
Therefore, from Pythagoras Theoreom:
hyptenous² = height² + base²
Distance² = change in y² + change in x²
Distance = √change in y² + change in x²

Many credit card companies charge a compound interest rate of 1.8% per month on a credit card balance. Nelson owes $950
Answer:
950, 1121.00, 1322.78, 1,560.88, 1,841.84
Step-by-step explanation:
Calculation to determine the sequences that describes his increasing monthly balance
Based on the information given in order for us to determine the sequence we have to multiply the amount owes by the interest rate and then add back the answer you got to the previous amount you multiplied the interest rate to.
First sequence will be the amount he owes on a credit which is $950
Second sequence
950 * .018 = 171.00
950 + 171.00 = 1121.00
Third sequence
1121.00 * .018 = 201.78
1121.00 + 201.78 = 1322.78
Fourth sequence
1322.78*0.18=238.10
1322.78+238.10=1,560.88
Last sequence
1,560.88*0.18=280.96
1,560.88+280.96=1,841.84
Therefore the sequences that describes his increasing monthly balance are:
950, 1121.00, 1322.78, 1,560.88, 1,841.84

In the figure the triangle is right triangle at *Y* and *N* is the foot of the perpendicular from *Y* to XZ. Given that XY=6 cm and XZ=10 cm. What is the length of XN
Answer:
3.6cm
Step-by-step explanation:
YZ = 10² - 6² = 8
sinX = 8/10 = 53.13º
cos 53.13º = XN/6
XN = 3.6cm

Let the length of XN be ' x ' & that of NZ be ' 10 - x 'In rt. XYZ :
Hypotenuse (h ) = 10 , Perpendicular ( p ) = YZ & Base ( b ) = 6Using Pythagoras theorem:

⇢ [tex] \large{ \sf{YZ = 8} \: cm} \: [/tex]
In rt. YNZ ,
Hypotenuse = 8 cm , Perpendicular = YN , base = 10 - xUsing Pythagoras theorem :

⇾ [tex] \large{ \sf{ {YN}^{2} = 64 - 100 + 20x - {x}^{2} }}[/tex]
⇾ [tex] \large{ \sf{ {YN}^{2} = 20x - {x}^{2} - 36}} \longrightarrow \: eq (i)[/tex]
In rt. XYN ,

The right rectangular prisms are similar. The bigger prism has a length of 2.2, width of .8, and height of 3.2. The smaller prism has a length of 1.1, width of .4, and height of 1.6.
Which statements are correct? Check all that apply.
- The angles in the smaller prism measure 90 degrees.
- The perimeter of the rectangular bases changes by a factor of 2.
- The surface area changes by a factor of 8.
- The larger prism has twice the volume of the smaller prism.
- The area of the rectangular bases changes by a factor of 4.
Answer:
The angles in the smaller prism measure 90 degrees.
The perimeter of the rectangular bases changes by a factor of 2.
The area of the rectangular bases changes by a factor of 4.
Step-by-step explanation:
Two polygons are said to be similar if they have the same shape and angles. Also, the ratio of their corresponding sides are to be in the same proportion.
A) Since the two prism are similar, therefore they are to have the same angle measure. The bigger prism has angles with measure of 90°, hence the angles in the smaller prism will also measure 90.
B) Perimeter of bigger prism base = 2(2.2 + 0.8) = 6
Perimeter of smaller prism base = 2(1.1 + 0.4) = 3
Hence, The perimeter of the rectangular bases changes by a factor of 2 (6 / 3).
C) Surface area of bigger prism = 2(2.2*0.8 + 3.2*0.8 + 3.2*2.2) = 22.72
Surface area of smaller prism = 2(1.1*0.4 + 1.6*0.4 + 1.6*1.1) = 5.68
22.72 / 5.68 ≠ 8, hence the surface area does not change by a factor of 8
Option C is wrong
D) Volume of bigger prism = 3.2 * 2.2 * 0.8 = 5.632
Volume of smaller prism = 0.4 * 1.6 * 1.1 = 0.704
The volume of larger prism is not twice of the smaller prism (5.732 / 0.704 ≠ 2)
E) Area of bigger prism base = 2.2*0.8 = 1.76
Area of smaller prism base = 2.2*0.8 = 0.44
Since 1.76 / 0.44 = 4; The area of the rectangular bases changes by a factor of 4

Find the area of the SHADED region.
Round to the nearest TENTH if necessary.
Answer:
The area of the SHADED region is 21 cm.²
Step-by-step explanation:
The area of the SHADED region is the difference between the area of the entire figure and the area of the UNSHADED region
The shape of the UNSHADED region is a rectangle
The area of a rectangle, A = The length × The width
∴ The area of the UNSHADED region, A = 1 cm × 4 cm = 4 cm²
The area enclosed by the entire figure is in the shape of a square
The area of a square s similar to the area of the rectangle, but because a square has equal side length, the area of a square, A = Side length × Side length
Therefore, the area enclosed by the entire figure = 5 cm × 5 cm = 25 cm²
The area of the SHADED region = The area enclosed by the entire figure - The area of the UNSHADED rectangular figure inside
That is the area of the SHADED region = 25 cm² - 4 cm² = 21 cm².
