Use the number line to show and explain why 4/10 ÷ 2 and 4/10 × 1/2 both equal 2/10
Step-by-step explanation:
When you divide by a number, you basically are multiplying by the reciprocal
The reciprocal of 2 is 1/2
4/10 ÷ 2 = 4/10 × 1/2 = 2/10
4/10 × 1/2 = 2/10
Using a number line,
Start at 4/10 and move down by 2 until you reach 0
Start at 4/10 and move up by 1/2 from 0 until you reach 4/10
(Count the number of humps)
Both will be the same

what is -2/3 times -12. This questions is related to converting slope point form into slope intercept form.
Answer:
-2/3 times -12=8
Step-by-step explanation:
Use the figure below to solve for the value of x.
Given:
A figure of a right triangle and an altitude form the right angle vertex to hypotenuse.
To find:
The value of x.
Solution:
From the given figure, it is clear that the altitude divides the hypotenuse in two segments x and 8.
Length of altitude = 18
If an altitude divide the hypotenuse in 2 segments, then according to the geometric mean theorem, the length of the altitude is the geometric mean of two segments of hypotenuse.
By using geometric mean theorem, we get
[tex]18=\sqrt{x\times 8}[/tex] [tex][\because \text{Geometric mean of }a,b,c:b=\sqrt{ac}][/tex]
[tex]18^2=8x[/tex]
[tex]324=8x[/tex]
Divide both sides by 8.
[tex]\dfrac{324}{8}=x[/tex]
[tex]40.5=x[/tex]
Therefore, the value of x is 40.5.
Which value for x makes the following equation TRUE? x 9 + 16 = 20
A. 4/9
B. 20/9
C. 13
D. 36
Answer:
A. 4/9
Step-by-step explanation:
Given
x 9 + 16 = 20
When x = 4/9 Then
4/9 * 9 + 16 = 20
4 + 16 = 20
20 = 20
Hope it will help :)
Angle A is a supplementary to Angle B. If < b = 65 degrees what is the value of x if < A = 5x -20 ?
Answer:
x = 27
Step-by-step explanation:
Supplementary angles add up to 180 degrees
65 + 5x - 20 = 180
45 +5x = 180
5x = 135
x = 27

Find X. This is a 40°, 40°, 90° triangle.
Answer:
In a 45°−45°−90° triangle, the length of the hypotenuse is √2 times the length of a leg. To see why this is so, note that by the Converse of the Pythagorean Theorem , these values make the triangle a right triangle. Note that an isosceles right triangle must be a 45°−45°−90° triangle.
Step-by-step explanation:
determine the missing angle
Answer:
106°
Step-by-step explanation:
These angles are alternate interior, therefore they are equal to each other.

In ARST, r = 52 cm, s = 55 cm and ZT=48°. Find the length of t, to the nearest
centimeter.
9514 1404 393
Answer:
44 cm
Step-by-step explanation:
The law of cosines is applicable.
t^2 = r^2 + s^2 -2rs·cos(T)
t^2 = 52^2 +55^2 -2·52·55·cos(48°) ≈ 1901.57
t ≈ √1901.57 ≈ 43.607
The length of t is about 44 cm.

[tex]{\underline{\boxed{\frak{\pmb{\quad {t}^{2} = {r}^{2} + {s}^{2} - 2rs \times cos(T) }}}}} [/tex][tex]\implies\tt[/tex] t² = (52)² + (55)² - 2 × 52 × 55 × cos(48°)
[tex]\implies\tt[/tex] t² ≈ 1901.57

Ok so you have 2 pies.
You can cut into quarters which is 4 slices in 1 pie.
Than you can do 4 slices x 2 pies which means you have 8
A pair of shoes is on sale for 30% off. The original price is p. Which expression can be used to find the price of the shoes after the discount? 0.30p 0.70p 1.30p 30p
Answer:
0.30p
Step-by-step explanation:
(px30)/100=0.3p
Answer:
0.70 p
Step-by-step explanation:
If the item is 30% off, the new price is 0.7p because we want to know how much 70% of the original price was.

g(x)=-|x| ; find g(-4)
Answer:
-4
Step-by-step explanation:
Plug in -4 for x, so the absolute value of -4 is 4. However, there's a minus sign out in front still, so it gets tacked on to the 4. So, g(-4)=-4

In ΔFGH, h = 9.6 inches, f = 2.5 inches and ∠G=78°. Find the length of g, to the nearest 10th of an inch.
Answer:9.4
Step-by-step explanation:
Answer: 9.4
Step-by-step explanation:
S.A.S.→Law of Cosines
a^2=b^2+c^2-2bc\cos A
g^2 = 9.6^2+2.5^2-2(9.6)(2.5)\cos 78
g^2 = 92.16+6.25-2(9.6)(2.5)(0.207912)
g^2 = 92.16+6.25-9.97976
g^2 = 88.43024
g=√88.43024 ≈9.404≈9.4

The area of a parallelogram is 16 cm. One side Height is 4 cm. What is the length? options are:- 5 cm none of these 4cm 8cm
Answer: 4cm
Step-by-step explanation:
The area of a parallelogram is calculated by multiplying the height by the length:
Area = Height * length
Assume the length is x, substituting values would make the formula:
16 = 4 * x
4x = 16
x = 16/4
x = 4 cm
