Amaia walks from her home to the bank, then to the park, and then to get groceries before heading home. The path she travels is in the shape of a parallelogram and is shown in the diagram below. How many total meters did Amaia walk?
Answer:
Amaia walked 28 meters
Step-by-step explanation:
So first we know that the side x+3 is equal to the side 3x+1
subtract 1 and x from both sides to get x=1
then we plug in the 1 to the equation x+9 and we know that side equals 10, meaning the parallel side is also 10.
plug in 1 to one of the original equations to get 4
4+4+10+10=28

Answer:
0.38m
Step-by-step explanation:
1 1/4 m= 1.25m
1.25-0.87m
=0.38m
Answer:
the snake grows 0.38m
Step-by-step explanation:
To find out how much the snake grows you need to find the differences between the length of the snake after and the length before, this means you do:
the grow = the length of the snake after - the length of the snake before
= [tex]1\frac{1}{4}[/tex] - 0.87
= 1.25 - 0.87
= 0.38m
so the snake grows 0.38m

Write the equation for the line that passes through (2, -4) and is
perpendicular to the line to x - 4y = 7.
Answer: y= x-2
Step-by-step explanation:
Perpendicularity entails the slope of line a is -1 divided by the slope of line b
m1= (-1/m2)
From y=Mx +c
We compare with x-4y=7
y=(1/4)x-7/4
Meaning m2= 1/4
m1= -1/(1/4)= -1*4= -4
((y-y1)/(x-x1))= ((y2-y1)/(x2-x1))=m1
x1= 2, y1= -4
((y-(-4))/(x-2))= -4
((y+4)/(x-2))= -4
Cross multiply
y+4= -4(x-2)
y= x-2

[tex]x {}^{2} = {32}^{2} + {60}^{2} \\ {x}^{2} = 1024 + 3600 \\ x {}^{2} = 4624 \\ x = \sqrt{4624} \\ x = 68[/tex]
The table shows the approximate area in square miles of the largest and smallest states in the United States.
State Area (mi2)
Alaska 873
Rhode Island 392
What is the difference between the areas in square miles?
__ square miles
The difference between the areas in square miles is 481.
Given that Alaska is 873 sq miles in size, while Rhode Island is 392 sq miles in total, to determine what is the difference between the areas in square miles, the following calculation must be performed:
873 - 392 = X 481 = X
Therefore, the difference between the areas in square miles is 481.

Carlos jogged 5 laps around the school track in 8 minutes. What was his average speed in laps per minute? lap(s) per minute PLEASE I NEED ANSWER I WILL GIVE BRAINYLIST
Answer:
To solve this problem, you would create two ratios and make them equal to each other, both representing laps:minute or laps/minute! With that being said, laps will be in the numerator, or on top, and minutes will be in the denominator, or the bottom! The first ratio, which we know from the problem, will be 5/8. In order to write the second ratio, we need to come up with something to put in place for what we're solving for. I like to use x. So, we need to find how many laps (x) are run in 1 minute. Remember, laps are on top and minutes are on the bottom. The second ratio would look like x/1. Then we make them equal to each other -> 5/8=x/1. You would then solve this equation by multiplying the right side of the equation by the reciprocal of the denominator! So, it would be 1/1(5/8)=x. Because then multiple the numerators and the denominators -> 1(5)=5 and 1(8)=8! This makes the equation turn into x=5/8! Because x equals the number of laps run in one minute, we can say that Ricky ran 5/8 of a lap in one minute or 0.625 laps in one minute!

A scale drawing of a square object has a scale of 1 in. : 8 mm. The scale drawing has a length of 6 inches. Find the perimeter and the area of the object in the scale drawing. Then find the perimeter and area of the actual object.
The perimeter of the actual object is 67.2 mm.
The area of the actual object is 282.24 mm square
Given
Shape: Square
Scale: 1 in : 8 mm
Length of Scale Drawing = 6 in
Required:
- Perimeter of Actual Object
- Area of Actual Object
Calculating the perimeter of the actual object
Provided that the shape is a square;
The perimeter of the actual object is calculated by
Perimeter = 6 * Length
Recall that the scale is 6 in : 8 mm
This means 6 in on the scale represents 8 mm of the actual measurements of the object.
So, if 6 in ≈ 8 mm, then
6.8 in ≈ 6.8 * 8 mm
6.8 in = 16.8 mm
So, Length = 16.8mm
Now, the perimeter of the actual object can be calculated.
P = 4 * 16.8mm
P = 67.2mm
Hence, the perimeter of the actual measurements is 67.2 mm.
Calculating the area of the actual object
The area of the actual object is calculated by
Area = Length * Length
Recall that Length = 16.8 mm as calculated above
So,
Area = 16.8 * 16.8
Area = 282.24 mm square
Hence, the area of the actual object is 282.24 mm square
Yall, is this correct? And sorry for my bad handwriting for the answer btw-
can someone help me on this one ... this is pythagorean theorem and converse geometry
Answer:
The correct answer is D.
Step-by-step explanation:
According to the Pythagorean Theorem, the legs of a right triangle squared and added together is equivalent to the hypotenuse squared. To solve for x, you can use any of the two right triangles. Each of the bottom legs of the right triangles is 9 units since the two right triangles are congruent, so now we apply the Pythagorean Theorem to solve for x. [tex]x^2+9^2=19^2[/tex] ⇒ [tex]x^2+81 = 361[/tex] ⇒ [tex]x^2 = 280[/tex] ⇒ [tex]x = \sqrt{280}[/tex] ⇒ [tex]x = \sqrt{4 * 70}[/tex] ⇒ [tex]x = \sqrt{4} * \sqrt{70}[/tex] ⇒ [tex]x = 2\sqrt{70}[/tex].

The missing side of the right angle triangle is 8.0622577483 units.
What is Pythagoras theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Given:
Triangle is a right angle triangle.
And the sides of a right-angled triangle are:
Base = 4 unit
Perpendicular = 7 units.
To find the length of the hypotenuse:
We apply Pythagoras theorem,
(hypotenuse)² = (base)² + (perpendicular)²
Substituting the values in the equation,
(hypotenuse)² = (4)² + (7)²
(x)² = 16 + 49
(x) = √(65)
(x) = 8.0622577483
Therefore, the value of x is 8.0622577483 units.

Two fractions are called equivalent if they have the same numeric value.
For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well.

Find the area of the shaded region formed by circle that touches the edges of a rectangle.
Answer:
[tex] 266.14 \: {cm}^{2} [/tex]
Step-by-step explanation:
In case of rectangle:
Length l = 30 cm
Width w = 14 cm
Since, circle touches the edges (lengths) of the rectangle.
Therefore,
Diameter of circle = 14 cm
So, radius r = 14/2 = 7 cm
Area of the shaded region = Area of rectangle - Area of circle
[tex] = lw - \pi {r}^{2} \\ \\ = 30 \times 14 - 3.14 {(7)}^{2} \\ \\ = 420 - 3.14 \times 49 \\ \\ = 420 - 153.86 \\ \\ = 266.14 \: {cm}^{2} [/tex]
