Are the two triangles similar? How do you know (What Theorem)?

Answers

Answer:

They are similar because of the SAS triangle similarity theorem.

Step-by-step explanation:

The angles in the interconnection of the two triangles are the same because they have the same vertex and lines.

The two sides are similar by a ratio of 1.5.

9/6 and 6/4 both equal to 1.5, which means that they have the same ratio.

Because there is a side that's similar, an angle that's congruent, and then a side that's similar, you can say that the triangles are similar basing on the SIDE-ANGLE-SIDE triangle similarity theorem.

Answers

Answer:

49x + 114

Step-by-step explanation:

[   [ fireplace ] x   = area of 5[tex]x^{2}[/tex]                   ]  x + 6

     5x

   patio               = area of 5[tex]x^{2}[/tex] + 49x + 114

5x + 19

 

(5x + 19) ( x + 6) = 5[tex]x^{2}[/tex] + 19x + 30x + 114

(5[tex]x^{2}[/tex] + 49x + 114)                     -   (5[tex]x^{2}[/tex] )                         =           49x + 114

Jacob made two trips to the store. On his first trip to the store, he
bought x kitchen towels for $3 each and y dishcloths for $2 each and spent
a total of $32. On his second trip to the store, he bought x oven mitts for $5
each and returned the y dishcloths he bought on the first trip. He was
refunded the money for the dishcloths and still spent $32. The system of
equations shown below represents the amounts, in dollars, he spent on the
two trips to the store.
3x + 2y = 32
5x - 2y = 32
How many kitchen towels and dishcloths did Jacob buy on his first trip to the
store?
o 10 kitchen towels and 4 dishcloths
o 4 kitchen towels and 10 dishcloths
04 kitchen towels and 8 dishcloths
8 kitchen towels and 4 dishcloths

Answers

Answer:

8 kitchen towels and 4 dishcloths!

Step-by-step explanation:

first equation is 3x + 2y = 32

second equation is 5x - 2y = 32

add the two equations together to get 8x = 64

solve for x to get x = 64 / 8 = 8

replace x with 8 in the first equation to get 24 + 2y = 32  

solve for y to get y = 8/2 = 4

you have x = 8 and y = 4

first equation becomes 24 + 8 = 32

second equation becomes 40 - 8 = 32

the solution checks out ok.

solution is x = 8 and y = 2 which means he bought 8 kitchen towels and 4 dishcloths on his first trip.

find the area of the square whose perimeter is 224cm​

Answers

Answer:

3,136cm^2

Step-by-step explanation:

A square has 4 sides that are all equal to each other. This means the perimeter can be divided by the number of sides to find the measurement of each side.

224cm ÷ 4 = 56cm

Each side is 56cm

To find the area, we must multiply base and height. Since it is a square, it will be 56cm × 56cm.

56cm × 56cm = 3,136cm^2

Answer:

3136cm²

Explanation:

to find the area of the square, we first need to find the length of one of its sides. the perimeter is the total length of all 4 sides, so we can divide it by 4 to find the length of each side.

224 ÷ 4 = 56

now, we can square this to find the area of the square:

56² = 56 × 56 = 3136

thus, the area of the square is 3136cm².

A right triangle has legs that are 5 cm and 7 cm long what is the length of the hypotenuse

1.√12
2.√24
3.√74
4.√144

Answers

Answer:

3. 74

Step-by-step explanation:

The pythagorean theorem states that A^2 + B^2 = C^2 (with c being the hypotenuse). So to figure it out we can substitute into the equation.

5^2 = 25

7^2 = 49

25 + 49 = 74

So it would be the square root of 79. I hope this helps! :)

The length of the hypotenuse side of a triangle is √74. Therefore, the correct answer is option 3.

What is the Pythagoras theorem?

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

Given that, a right triangle has legs that are 5 cm and 7 cm long.

Let the length of the hypotenuse side be x.

Now, x²=5²+7²

x²=25+49

x²=74

x=√74 units

Therefore, option 3 is the correct answer.

A linear function has an x-intercept of -8 and a y-intercept of 4. Which of these is an equation of the linear function?

Answers

Answer:

x-2y=-8

Step-by-step explanation:

it is what it is

The equation of the linear function having an x-intercept of -8 and a y-intercept of 4 is y = (1/2)x + 4.

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, A linear function has an x-intercept of -8 and a y-intercept of 4.

So, The two points on the line are (- 8, 0) and (0, 4).

Now, slope(m) = (4 - 0)/(0 + 8).

slope(m) = 4/8.

slope(m) = 1/2.

As it has a y-intercept of 4 it is the value of b, In y = mx + b.

Therefore, The linear function is y = (1/2)x + 4.
