Answer:
No
Step-by-step explanation:
As you probably know, triangles have 3 sides. The longest side is called the hypotenuse. In this case, the hypotenuse is 10.3. Now, you might or might not know the pythagorean theorem, which states that the a² + b² =c ².
In this case, we can say that 4.4 is a and 8.3 is b. Now if we square 4.4 and add it to 8.3 squared, we get 88.25. However, if you square 10.3, you get 106.09. Thus, the values cannot be this way. So, your answer is no.

Answer:
90 - 43 = x
Step-by-step explanation:
Answer: 47
Step-by-step explanation:
Dude just subtract 43 from 90, since you are given a 90 degree angle.
But if you need the equation: 43+x-7=90
add 43 and (-7) which gives us 36
new equation is now: 36+x=90
move the 36 to the other side
x=54
now plug it in x(54)-7=47

In right △ABC altitude overlineBD is drawn to hypotenuse overline{AC} If AD = 5 and BC = 2√ 21, find DC, BD, and ABAB.
Answer:
[tex]\overline {DC}[/tex] = 7
[tex]\overline {BD}[/tex] = √35
[tex]\overline {AB}[/tex] = 2·√15
Step-by-step explanation:
Please find attached the drawing of right triangle ABC created with MS Visio
Let 'x' represent [tex]\overline {BD}[/tex] let 'y' represent [tex]\overline {DC}[/tex], and let 'z' represent [tex]\overline {AB}[/tex], we get;
5² + x² = z²...(1)
x² + y² = (2·√21)² = 84
x² + y² = 84...(2)
84 + z² = (5 + y)²...(3)
From equation (1), we have;
x² = z² - 5²...(4)
From equation (2), and equation (4), we have;
x² + y² = 84 = (z² - 5²) + y² = 84
∴ z² = 84 - y² + 5² = 109 - y²
z² = 109 - y²...(5)
From equation (3), and equation (5), we have;
84 + z² = (5 + y)² = 84 + (109 - y²) = (5 + y)²
84 + (109 - y²) = (5 + y)²
(5 + y)² - (84 + (109 - y²)) = 0
2·y² + 10·y - 168 = 0
y² + 5·y - 84 = 0
y = (-5 ± √(5² - 4 × 1 × (-84)))/(2 × 1)
y = 7, or y = -12
We note that 'y' is a natural number, therefore, the correct option of the two options is y = 7
y = [tex]\overline {DC}[/tex] = 7
From equation (2), we have;
x² + y² = 84
x² = 84 - y² = 84 - 7² = 35
x = √35
x = [tex]\overline {BD}[/tex] = √35
z² = 109 - y²
∴ z² = 109 - 7² = 60
z = √60 = 2·√15
z = 2·√15
z = [tex]\overline {AB}[/tex] = 2·√15.
help me please i love you<33
Answer:
<B = 95degrees
<D = 137 degrees
Step-by-step explanation:
From the given diagram, the sum of the adjacent sides of the trapezoid is 180degrees. Hence;
<A +<B = 180
85 + <B = 180
<B = 180 - 85
<B = 95degrees
Similarly
<C + <D =180
43 + <D = 180
<D = 180 - 43
<D = 137 degrees
Find the value of the missing indicated angle. Show all work.
Help please ??
Answer:
77.5 degrees
Step-by-step explanation:
sin(90)/42=sin(?)/41
sin(90)/42 times 41=0.9761904
sin^-1(0.9761904)=77.47209456 degrees

Billy and Tommy are playing a dice game with a six-sided die. Billy needs to roll a 5 or higher to win the game. What is the probability that Billy will roll a 5 or higher?
Answer:
Probability that Billy will roll a 5 or higher [tex]=\frac{1}{3}[/tex]
Step-by-step explanation:
Probability refers to chances of occurrence of any event.
If a six-sided die is thrown, possible outcomes are [tex]1,2,3,4,5,6[/tex].
Billy needs to roll a 5 or higher to win the game.
So,
Favorable outcomes are [tex]5,6[/tex]
Number of favorable outcomes [tex]=2[/tex]
Total number of outcomes [tex]=6[/tex]
Probability that Billy will roll a 5 or higher
= Number of favorable outcomes ÷ Total number of outcomes
[tex]=\frac{2}{6}[/tex]
[tex]=\frac{1}{3}[/tex]

This graph shows both a reflection and a
translation. What function is being graphed?
y=-285
y = 3x - 2-1
O
y=-3/x-2-1
y=-3x + 2-1
Answer:
4th choice: y=-∛(x+2) - 1
Step-by-step explanation:
It's horizontal translation to left 2 units and vertical translation down 1 unit from y = -∛x
It's reflection of y = ∛(x-2) - 1 over y axis

Ten points! Teresa's family is thinking about buying a family pass to a gym. The pass is $120 for a family of 6. Individual passes are $25 each. How much money can Teresa's family save by purchasing a family pass instead of 6 individual passes?
Answer: If Teresa‘s family bought individual passes it would be $150 so then if you subtract it would be $30. Teres’s family saved 30 dollars.
Step-by-step explanation:
They can save $30
Step-by-step explanation:
If the family pass is $120 and individual passes are $25 dollars.
6 people times $25 dollars = $150
Family pass: $125
$150-$125=$30
A length, originally 6cm, is inecased so that the ratio of the new
length to the old length is 9:2. What is the new length?
How do I get the answer to question #5?
Answer:
7 cm
Step-by-step explanation:
Area of a parallelogram formula:
[tex]A=bh[/tex] where b is the base length and h is the height
Plug in known values (A=112, b=16 and h=x)
[tex]112=16x[/tex]
Divide both sides by 16 to isolate x
[tex]\frac{112}{16} = \frac{16x}{16}\\7=x[/tex]
Therefore, x is equal to 7 cm.

equivalent expression for 4(2x+1) and for 1/2 (4x-8)
Answer:
8x+4 and 2x-4
Step-by-step explanation:
We are going to use factoring to make equivalent expressions. What you do is you take the number next to the parenthesis and multiply it with what is inside the parenthesis. So it would be 8x+4 and 2x-4. Hope this helps! :)

Step-by-step explanation:
Blake collects stamps. He collected a total of 175 stamps. If 72% of the stamps he collected were
foreign, how many other stamps did he collect?
Blake collected stamps that were not foreign.
(Type a whole number.)
Answer: 49
Step-by-step explanation:
If 72% of the stamps he collected were
foreign, the percentage of the other stamps will be: = (100% - 72%) = 28%
Since the total number of stamps collected are 175, the number of other stamps collected will be:
= 28% of 175
= 28% × 175
= 28/100 × 175
= 0.28 × 175
= 49
Therefore, he collected 49 other stamps that were not foreign

Answer:
The area is: 4x^5 + 8x^3
Equation: (2x^3 + 4x) * 2x^2
^ = exponent
* = multiply
Step-by-step explanation:
When you try to find the rectangle of an area, the formula is:
Length * Width
In this case, the length is:
2x^3 + 4x
And the width is:
2x^2
Now let's solve the equation.
(2x^3 + 4x) * 2x^2
We need to combine like terms
2x^3 + 2x^2 = 4x^5
After evaluating the equation:
4x^5 + 8x^3
The area is: 4x^5 + 8x^3
