Which equation can be used to find x,the length of the hypotenuse of the right triangle
Answers
18^2 + 24^2 = x^2 <==
** the hypotenuse is always the longest side..it is the side opposite the right angle
Answer:
[tex]x^{2}=24^{2}+18^{2}[/tex]
Step-by-step explanation:
we know that
The Pythagoras Theorem states that in a right triangle
[tex]c^{2}=a^{2}+b^{2}[/tex]
where
c is the hypotenuse
a,b are the legs of the right triangle
In this problem we have
[tex]a=24\ units, b=18\ units, c=x\ units[/tex]
substitute
[tex]x^{2}=24^{2}+18^{2}[/tex]

The perimeter of the following rectangle is 40 inches. What is the length of w?
Bottom: 14 in.
Side: Unknown
2.9 in.
6 in.
12 in.
26 in.
Answers
6 inches is the answer
P= 2( L+W)
Answer: 6 inches
Step-by-step explanation:
Given: The perimeter of the rectangle = 40 inches
Let the unknown side be w.
And the bottom side l=14 in.
We know that the perimeter of rectangle is given by :-
[tex]\text{Perimeter}=2(l+w)\\\Rightarrow40=2(14+w)\\\Rightarrow\frac{40}{2}=14+w\\\\Rightarrow20=14+w\\\Rightarrow\ w=20-14)\\\Rightarrow w=6\ in.[/tex]
Hence, the the length of w = 6 inches.

A rope stretches directly depending on the load it must carry. If a load of 8 pounds stretches the rope 9.6 inches, the constant of proportionality is equal to:
8(9.6)
8/9.6
9.6/8
Answers
"Our proportionality constant would be how much the rope stretches versus the weight being hung. This is set up by simply dividing the two numbers.
9.6 inches / 8 pounds
or for every pound hung, it will stretch 1.2 inches so we know if it stretches 6 inches, we can set up an equation 6 inches = 1.2 [inches/pound] * pounds solve for weight to get 5 pounds being hung from the rope."

A number line contains points Q, R, S, and T. Point Q is on the coordinate 24, R is on the coordinate 28, S is on the coordinate 29, T is on the coordinate 42. Find the probability that a point chosen at random on QT is on ST. Express your answer as a percent.
25%
42.2%
50%
72.2%
Answers
P(ST)=(42-29)/(42-24)
P(ST)=13/18
As a percentage:
(p/100)=(13/18)
p=1300/18%
p=650/9%
p≈72.2% (to nearest tenth of a percent)
Answer:
The correct option is 4.
Step-by-step explanation:
It is given that Point Q is on the coordinate 24, R is on the coordinate 28, S is on the coordinate 29, T is on the coordinate 42.
Total numbers lie on line QT is
[tex]42-24=18[/tex]
The numbers lie on line ST is
[tex]42-29=13[/tex]
The probability that a point chosen at random on QT is on ST is
[tex]P=\frac{\text{The numbers lie on line ST}}{\text{Total numbers lie on line QT}}\times 100[/tex]
[tex]P=\frac{13}{18}}\times 100[/tex]
[tex]P=72.222\approx 72.2\%[/tex]
The probability that a point chosen at random on QT is on ST is 72.2%. Therefore option 4 is correct.
A window has the shape of a rectangle with a semi circle at the top. Find the approximate area of the window using the dimensions shown.
2ft by 4ft
Answers
Area of a circle = π*r²
Looking at the rectangle, the diameter for the circle is 2 ft. Since we need the radius though, divide the diameter by 2 to get the radius.
r = 1
A = π * 1²
A = π * 1
A = π
But since it's a semicircle, you need to divide that area by 2.
3.14/2 = 1.57
The area of the semi-circle is 1.57.
Area of a rectangle = lw
l = 2
w = 4
A = 2 * 4
A = 8
The area of the rectangle is 8.
Now add those together to get the area of the entire figure.
1.57 + 8 = 9.57
The figure is about 9.57 square feet.
The approximate area of the window is 9.57 ft²
The figure is a composite shape. Therefore, the area can be described as follows:
Area of the composite shape:area = area of semi circle + rectanglearea of a rectangle = lw = 4 × 2 = 8 ft²
area of the semi circle = 1 / 2 πr² = 1 / 2 × π × 1² = 1.57 ft²
Therefore,
area of the window = 8 + 1.57 = 9.57 ft²

Robert buys 3 pounds of bananas at $0.50 per pound and 3 pounds of apples at $1.00 per pound. Which of the following expressions represents the total cost of the fruit he bought (in dollars
Answers
Answer:
The answer is $3(0.50+1.00)
Step-by-step explanation:
Robert bought 3 pounds of bananas at $0.50 per pound which can be expressed as:
[tex]3*0.50[/tex]
And 3 pounds of apples at $1.00 per pound which can be expressed as:
[tex]3*1.00[/tex]
As Robert bought the apples and bananas, you can add both expressions:
[tex]3*0.50 + 3*1.00[/tex]
This expression can be factorized as:
[tex]3(0.50+1.00)[/tex]
or
[tex]3(1.50)[/tex]
Both expressions will give you the same result, which is $4.50.
