step 1
3/4+5/4
step 2
dinominator is same so we have to put 4
step 3
3+5/4
step 4
7/4
answer is 7/4
Answer:
2
Step-by-step explanation:
Given
[tex]\frac{3}{4}[/tex] + [tex]\frac{5}{4}[/tex]
Since the denominators are common, both 4 then add the numerators leaving the denominator
= [tex]\frac{3+5}{4}[/tex]
= [tex]\frac{8}{4}[/tex]
= 2
Find the x of a triangle.

Skateboarders use half pipes for doing tricks A half-pipe is similar to a half cylinder which is not enclosed on the ends.
a. Explain how you could manipulate the surface area formula for a cylinder to calculate the curved surface area of the half pipe.
b. To the nearest square metre, calculate the curved surface area of the half pipe if it is 9 m long?
Answer:
Step-by-step explanation:
a). Total surface area of cylinder is defined by sum of curved surface area and surface area of the top and bottom.
Total surface area = 2πrh + 2πr²
Skateboarders use a half pipe structure which are not closed at the ends.
Therefore, curved surface of the half pipe = [tex]\frac{2\pi rh}{2}[/tex]
= πrh
b). If r = 2.5 m and h = 9 m,
Curved surface area of the half pipe = π(2.5)(9)
= 70.69 m²
≈ 71 m²

Answer:
only Y
Step-by-step explanation:
all the others have for at least 1 value of x more than one different y values defined.
but a function must be clear about the association between an x unit value and the corresponding result.
many different input values can have the same functional result. but there can be only one defined result per input value. otherwise it is not a function.
you cannot say 1+1 = 2 or 3. it is either 2 or 3, but you need to define what. you can't leave it open.
The function is given by the table Y
x = { -3 , 2 , 0 , 3 } and y = { 1 , 1 , 1 , 1 }
What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as A
Now , the value of A is
Let the x values of the function be represented as
x = { -3 , 2 , 0 , 3 }
Now , the y values of the function is
y = { 1 , 1 , 1 , 1 }
From the table , we can see that for every different values of x there are range of values of y
No two same values of ranges have the same domain
Therefore , it is a function
Hence , the function is table Y

Find the measure of the third angle of a triangle if the measures of the other two angles are given.
118.6 and 42.3
The three inside angles of a triangle equal 180.
Subtract the two known angles from 180.
180 - 118.6 - 42.3 = 19.1
The third angle is 19.1

Answer: y = -4x - 4
Step-by-step explanation:
Point slope form: y - y1 = m(x - x1)
Plug in y1 and x1, and m. M is the slope, x1 and y1 are the values for a coordinate. You don't need to plug anything in for y or x, just y1 and x1.
First, find the slope. To find the slope, use this "formula" : [tex]slope=\frac{rise}{run} =\frac{y1-y2}{x2-x1}[/tex]
Find two coordinate points. Let's use (-2,4) and (0,-4). Based on this, we know that y1 is 4, y2 is -4, x1 is -2, and x2 is 0. Plug these into the formula:
[tex]\frac{4--4}{-2-0} =\frac{4+4}{-2} =\frac{8}{-2}=-4[/tex]
Then, pick any point to plug into the equation. Let's use (0,-4)
Finally, plug everything into the equation:
y - - 4 = -4(x - 0)
y + 4 = -4x
y = -4x - 4
Answer:
[tex]y - 4 = - 4(x + 2)[/tex]
Step-by-step explanation:
Point Slope Form is a algebraic formula when we know a pair of points and it
slope.
It can be represented by
[tex]y - y_{1} = m(x + x _{1})[/tex]
where m is the slope and x 1 and y 1 are the points we know.
The coordinates we know are (-2,4) so we just plug it in.
We also know the slope of the line is rise/run. Look at point (-2,4). The next consecutive point before that is x intercept (-1,0). Let use the slope formula to find the slope
[tex] \frac{0 - 4}{ - 1 - ( - 2)} = \frac{ - 4}{1} = - 4[/tex]
So the slope or m is -4. Plug this in and the coordinates into point slope formula.
[tex]y - 4 = - 4(x - ( - 2)[/tex]
[tex]y - 4 = - 4(x + 2)[/tex]

A trapezoid is a rhombus.
A trapezoid is a parallelogram.
A trapezoid is a quadrilateral.
A trapezoid is a rectangle.
Answer:
„A trapezoid is a quadrilateral.” ⇒ trueStep-by-step explanation:
This is a trapezoid. It is a quadrilateral with one pair of parallel sides while other sides are non-parallel. Here, the opposite angles are alternate, that is, they have together 180°.
Isosceles trapezoid
An isosceles trapezoid is a trapezoid with congruent base angles and congruent non-parallel sides. Here, the base angles are the same.
The line segment joining the midpoints of the parallel sides is perpendicular to the bases and the diagonals are the same in length.
Right-angled trapezoid
Trapezoid with two right angles and necongruent non-paralell sides.

in the diagram above,PQR=125°, QRS=r,RST=80°and STU=44°. Calculate the value of r
Answer:
∆ PQR is congruent to ∆ STU
This means --
P = S
Q = T
R = U
R = 80°
S = P = 70°
So in ∆PQR, we know R = 80° , P = 70° and Q = ?
Using angle sum property of triangle,
P+ Q + R = 180°
70° + 80° + Q = 180°
150° + Q = 180°
Q = 30°

hello I’m new here ! But I’m having trouble understanding how my teacher factored out the A from a-a(1.2^4)? And made it to A(1-1.2^4)?
I attached a picture !
Thank you everyone :)
This is the distributive property:
ab + ac = a (b + c)
In this case, you have
a - a (1.2⁴)
and a is a common factor to both a and a (1.2)⁴, so you can pull it out as
a (1 - 1.2⁴)

Arturo is building a flower bed in the shape of a right triangle. The hypotenuse of the right triangle is 13 feet. One of the legs needs to be 7 feet longer than the other leg.
Which equation can be used to find x, the length of the shorter leg?
x(x + 7) = 13
x(x + 7) = 169
x2 + (x + 7)2 = 13
x2 + (x + 7)2 = 169
Answer:
x(x + 7) = 169
Step-by-step explanation:
We are given that
Let length of shorter leg of right triangle = x ft
Length of other leg = x+7 ft
Hypotenuse of right triangle = 13 ft
We have to find the equation which can be used to find x, the length of shorter leg.
By pythagorous theorem
(Hypotenuse)^2=(Base)^2+(Perpendicular\;side)^2
Substitute the values then, we get
(13)^2=x^2+(x+7)^2
x^2+(x+7)^2=169
This is required equation which can used to find x.
Answer:
d. x2 + (x + 7)2 = 169
Step-by-step explanation:
use Pythagorean theorem, substitute in the given values, and you get this

In the diagram, what is m NSR?
RU is a line which needs to equal 180 degrees. This means angle VSR + VSU needs to equal 180.
VSU = 100
VSR = 180 - 100 = 80
Answer: VSR = 80
Answer:
∠ VSR = 80°
Step-by-step explanation:
∠ VSR and ∠ VSU are adjacent angles and sum to 180° , then
∠ VSR + 100° = 180° ( subtract 100° from both sides )
∠ VSR = 80°
