Which is an irrational number between -9 and -10?
Answer:
maybe -9.1666 top second one?
Answer:
-sqrt85
Step-by-step explanation:
An irrational number is a number that cannot be written as fraction a/b where and b are integers
sqrt85 is simplified, and cannot be written as a/b with integers a and b, therefore -sqrt85 is irrational.
x + 3 = -x - 5 Solve
Answer:
x = -4
Step-by-step explanation:
x + 3 = -x - 5
subtract 3 from each side
x = -x - 8

What is the formula for slope?
Will give brainliest for first correct.
Answer:
To solve the problems in this lesson, students use the slope formula, which states that m = (y2 -- y1) / (x2 -- x1). The slope formula can be read as "slope equals the second y coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate".

445.76×9.634 is approximately equal to
Answer:
Step-by-step explanation:
It sounds like you are asked to estimate it. That's a very valuable skill.
9.634 is about 10
445.76 is about 446
So an approximate answer is 446 * 10 = 4460
How close is that to the actual answer? Let's find out.4294.45
On a test, if you get an answer like 4460 in your head, and your calculator says 4294.45, you are pretty certain that you have done the question correctly.
Similar triangles ABC and DEF are shown on the coordinate plane line t passes through points B, E, F, and C
Slope of BC = AB/AC, and Slope of EF = DE/DF
BC and EF both lie on the same line t, therefore the slope of BC equals the slope of EF.
What are Similar Triangles?Similar triangles are two triangles having the same shape but different sizes, however, the ratio of their corresponding sides are equal.
How to Find the Slope of a LineSlope = change in y / change in xSlope between any two points on the same line are the same.Given:
ΔABC ~ ΔDEF
Slope of BC = AB/AC
Slope of EF = DE/DF
BC and EF both lie on the same line t, therefore the slope of BC equals the slope of EF.

Find the volume, in cubic feet, of the composite solid below, which consists of a pyramid sitting on top of a cube. The pyramid has the same base as the cube.
Answer:
2,112 ft³
Step-by-step explanation:
Volume of composite solid = volume of pyramid + volume of cube
✔️Volume of square pyramid = ⅓(a²)*h
Where,
a = 12 ft
h = 8 ft
Plug in the values
Volume of pyramid = ⅓(12²)*8 = 384 ft³
✔️Volume of cube = a³
Where,
a = 12 ft
Plug in the value
Volume of cube = 1728 ft³
✔️Volume of composite solid = 384 + 1728 = 2,112 ft³
lindsey made 400 tarts. she sold 3/5 of them in morning and 1/4 of the remainder in the afternoon. how many tarts did she sell in the afternoon?
Answer:
40 tarts
Step-by-step explanation:
Lindsey had 400 tarts to start with, then she sold off 3/5 of them. Hence find the number of tarts left (2/5 of the original amount). Then she sold 1/4 of the remaining tarts. Therefore, find 1/4 or 2/5 of 400. The equation would be;
[tex](\frac{1}{4})(\frac{2}{5})(400)[/tex]

Make x the subject of the formula w − y x = z
Answer:
hmm ..
just transfer the X at the right side and others on left side
Step-by-step explanation:
so you get
w-z = yx
so later
(w-z)/y = x
The required value of x for the equation w - yx = z is (w - z)/y.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
The given equation is,
w - yx = z
Solve to determine the value of x,
Subtract w from both the sides,
w - yx - w = z - w
-yx = z - w
Multiply with -1 both the sides,
yx = w - z
⇒x = (w - z)/y
The value of x for the given equation is (w - z)/y.

In the figure below, ma = 7x + 5 and mb = 28x. The angles are
supplementary
Find the ma
b
a
40 degrees
140 degrees
35 degrees
5 degrees
Step-by-step explanation:
Since the 2 angles are supplementary,
(7x + 5°) + 28x = 180°.
=> 35x + 5° = 180°
=> 35x = 175°
=> x = 5°.
Hence Angle A = 7(5°) + 5° = 40°.

21.2
18.8
40.4
32.1
Answer:
x = 34.06
Step-by-step explanation:
The sum of angles in the triangle LUV is 180 degrees
Given
∠L=(3x+y)°
∠U=42.6°
∠V=(4x−3y−0.8)°
Since ∠L+∠U + ∠V = 180 degrees
Substitute:
3x+y + 42.6 + 4x - 3y - 0.8 = 180
7x - 2y - 41.8 = 180
7x - 2y = 221.8 ... 1
Since UV = UL, hence the triangle is isosceles and <V = <L
3x+y = 4x-3y - 0.8
-x +4y = -0.8
x - 4y = 0.8 ....2
From 2: x = 0.8+4y
Substitute into 1:
7x - 2y = 221.8
7(0.8+4y) - 2y = 221.8
5.6 + 28y-2y = 221.8
26y = 221.8-5.6
26y = 216.2
y = 8.32
Get x
x = 0.8+4y
x = 0.8+4(8.32)
x = 0.8 + 33.26
x = 34.06
Note that it was assumed that <V = <l since the question is not clear
