Answer:
52 units.
Step-by-step explanation:
Use the Triple 5-12-13
20 / 4 = 5
48/ 4 = 12
So the hypotenuse = 4 * 13 = 52.
The lengths of Hypotenuse 52 units.
What is Pythagoras Theorem?The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.
According to the Pythagoras theorem, the square of the hypotenuse of a triangle, which has a straight angle of 90 degrees, equals the sum of the squares of the other two sides.
Given:
The measurement of two sides are 20 units and 48 units.
Now, Using Pythagoras theorem
H² = P² + B²
H² = 20² + 48²
H² = 400 + 2304
H² = 2704
H = 52 units.
Hence, lengths of Hypotenuse 52 units.

There are oranges that are ¥90 and apples that are ¥150.
When you buy a total of 15 of them, your total cost is ¥1890.
How many oranges and apples did you buy?
Step-by-step explanation:
If 15 oranges were bought,
the total cost would be 15 * ¥90 = ¥1350.
¥1890 - ¥1350 = ¥540.
For every orange that switches to an apple,
the cost increases by ¥150 - ¥90 = ¥60.
Number of apples = ¥540 / ¥60 = 9.
Therefore there are 6 oranges and 9 apples.
Answer:
6 oranges and 9 apples.
Step-by-step explanation:
Let the number of oranges be x then the number of apples = 15 - x.
So 90x + 150(15 - x) = 1890
90x - 150x + 2250 = 1890
-60x = -360
x = 6
and number of apples = 15 - 6
So it's 6 oranges and 9 apples.

Answer:
position 1 5 8 12 19 25
term -8 8 20 36 64 88
Step-by-step explanation:
(n - 1) is position ( n ∈ N)
d is the distance between the numbers in the sequence
a1 is the first number in the sequence
we have the fuction: a(n) = a1 + (n - 1)d
see in the table, with position = 1, term = -8 => a1 + d = -8
position = 25, term = 88 => a1 + 25d = 88
=> we have: a1 + d = -8
a1 + 25d = 88
=> a1 = -12
d = 4
=> a(n) = -12 + 4(n - 1)
=> term = 8, position = (8 + 12)/4 = 5
position = 8, term = -12 + 4.8 = 20
term = 36, position = (36 + 12)/4 = 12
position = 19, term = -12 + 4.19 = 64
Answer:
The required table is:
Position 1 5 8 12 19 25
Term -8 8 20 36 64 88
Step-by-step explanation:
The general formula for arithmetic sequence is:
[tex]a_n=a_1+(n-1)d[/tex]
where n is the nth term, a₁ is the first term and d is the difference.
Looking at the table, we know that
a₁ = -8 and
a₂₅ = 88
We can find the common difference d:
[tex]a_n=a_1+(n-1)d\\n=25, a_1=-8, a_{25}=88\\a_{25}=a_1+(25-1)d\\88=-8+24(d)\\88+8=24\:d\\96=24\:d\\d=\frac{96}{24}\\d=4[/tex]
So, we have d = 4
Now we can fill the remaining table.
We have to find position n, when term (a_n) is 8
[tex]a_n=a_1+(n-1)d\\8=-8+(n-1)4\\8=-8+4n-4\\8=-12+4n\\8+12=4n\\20=4n\\n=\frac{20}{4}\\n=5[/tex]
So, when term is 8, position is 5
We have to find term a_n when position n is 8
[tex]a_n=a_1+(n-1)d\\a_8=-8+(8-1)4\\a_8=-8+7(4)\\a_8=-8+28\\a_8=20[/tex]
So, when position is 8 term is 20
We have to find position n, when term (a_n) is 36
[tex]a_n=a_1+(n-1)d\\36=-8+(n-1)4\\8=-8+4n-4\\8=-12+4n\\36+12=4n\\48=4n\\n=\frac{48}{4}\\n=12[/tex]
So, when term is 36, position is 12
We have to find term a_n when position n is 19
[tex]a_n=a_1+(n-1)d\\a_{19}=-8+(19-1)4\\a_{19}=-8+18(4)\\a_{19}=-8+72\\a_{19}=64[/tex]
when position is 19 term is 64
So, the required table is:
Position 1 5 8 12 19 25
Term -8 8 20 36 64 88
What is the rule used to reflect the triangle ABC to its image?
A. Reflect over y = -x
B. Reflect over y = x
C. Reflect over the x axis
D. Reflect over the y-axis
Answer:
The rule used to reflect Δ ABC to its image is Reflect over y = x ⇒ B
Step-by-step explanation:
If the point (x, y) reflected across the x-axis , then its image is (x, -y) If the point (x, y) reflected across the y-axis , then its image is (-x, y) If the point (x, y) reflected across the line y = x , then its image is (y, x) If the point (x, y) reflected across the line y = -x , then its image is (-y, -x)From the given figure
∵ The coordinates of point A are (-4.5, 6)
∵ The coordinates of point A' are (6, -4.5)
→ The coordinates are switched ⇒ 3rd rule
∴ Point A is reflected over the line y = x
∴ Δ ABC is reflected over the line y = x
∴ The rule used to reflect Δ ABC to its image is Reflect over y = x
Note: Point B' on the graph should be C' and point C' should be B' (correct it)

A computer manufacturer built a new facility for assembling computers. There were construction and new equipment costs. The company paid for these costs and made combined profits of $10 million after 4 years, as shown in the graph:
There is a graph of a line with Years on the x axis and Profits in millions on the y axis that passes through 0, negative 20 and 4, 10.
Which equation most closely represents the line depicted in the graph?
f(x) = −10x + 4
f of x equals fifteen halves times x minus 20
f(x) = 10x − 4
f of x equals two fifteenths times x minus 20
Given:
The graph passes through the points (0,-20) and (4,10).
To find:
The equation of line that most closely represents the line depicted in the graph.
Solution:
If a line passing through two points, then the equation of line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
The given line passes through the points (0,-20) and (4,10). So, the equation of line is
[tex]y-(-20)=\dfrac{10-(-20)}{4-0}(x-0)[/tex]
[tex]y+20=\dfrac{10+20}{4}(x)[/tex]
[tex]y+20=\dfrac{30}{4}x[/tex]
[tex]y+20=\dfrac{15}{2}x[/tex]
Subtracting 20 from both sides, we get
[tex]y=\dfrac{15}{2}x-20[/tex]
The function form is
[tex]f(x)=\dfrac{15}{2}x-20[/tex]
f of x equals fifteen halves times x minus 20.
Therefore, the correct option is B.
Answer:
Your answer is B
Step-by-step explanation:
f of x equals fifteen halves times x minus 20

Daryl biked for 12 minutes and traveled 1.6 miles. If He kept the same pace, how far would he travel in 3.5 hours? please show work if possible!!!!
Answer:
27.999999993 or 27.9 or 28 (rounded) miles.
Step-by-step explanation:
Find out how many miles he goes every minute.
(1.6 ÷ 12 = 0.13 recurring (0.1333333333)
3.5 hours = (60 × 3) + 30 = 210 minutes
Multiply 0.13 recurring (0.1333333333) by 210 mins.
210 × 0.13 recurring (above number) = 27.999999993 (You can round this up to the nearest whole number), which is 28 if the question asks you to but as it uses 1.6 miles, you can leave it as 27.9 or even leave the long decimal if you're not entirely sure.
Hope this helps. :)

The rate of change for the given function is 2.25. Therefore, option B is the correct answer.
What is rate of change of a function?The rate of change, or the slope, is calculated as Δy/Δx , or (y2−y1)/(x2−x1). The slope-intercept equation of a line is y=mx+b , where m is the slope and b is the initial value.
From the given table, we have (1, 4.5), (2, 6.75), (3, 10.125) and (4, 15.1875).
Using coordinate points (1, 4.5) and (2, 6.75), we get
Rate of change = (6.75-4.5)/(2-1)
= 2.25
Therefore, option B is the correct answer.

. Alex bought a new bike last weekend. It was $185 and he had to pay tax at a rate of 8%. How
much tax did he pay?
Answer:
$14.80
Step-by-step explanation:
Original bike price: $185
Tax: 8% OR 0.08 as a DECIMAL
To find your answer, multiply the bike price by the DECIMAL (number) tax amount:
185 x 0.08
= 14.8
Therefore, Alex paid $14.80 in tax.
Answer: $14.80
Step-by-step explanation:
We know: The bike is $185, and the tax is 8% of the product.
So we multiply them together.
185 * 8 / 100 = 14.8
or
185 * 0.08 = 14.8
The tax will be $14.80.
The other way to solve this question is by cross multiply.
[tex]\ \frac{x}{185} = \frac{8}{100}\[/tex]
But what you get would still be the same as just multiply it directly.
185*5/100 = 14.8

Four intersecting lines, t, v, u, and w, are shown in the diagram.
===============================================
Explanation:
Line w and line t are parallel if and only if the corresponding angles (4x+60) and (9x) are congruent.
9x = 4x+60
9x-4x = 60
5x = 60
x = 60/5
x = 12
If x = 12, then
9x = 9*12 = 108
4x+60 = 4*12+60 = 48+60 = 108
Both corresponding angles would be 108 degrees if x = 12. So this confirms we have the right x value.

Answer: He is not correct. The resulting will be in a different quadrant.
Step-by-step explanation: This would be much easier to answer with a screen shot of the image.
For example, if the original image is in quadrant 1, the first reflection over the x-axis places the new image in quadrant 4, "upside-down" and the second reflection over the y=x line places the new image in quadrant 2 and "oblique" to the original.
Reflecting the original over the y=-x line places the new image in quadrant 3.
