27 = -3x - 9 plssss helppp
Answer:
x = 1-2
Step-by-step explanation:
27 = - 3x - 9
36 = -3x
-12 = x
x = -12
Step-by-step explanation:
27+9=-3x
36=-3x
36 divided by -3=x
-12=x
Can someone help find the solutions
Answer:
x = 3.5
Step-by-step explanation:
Given
[tex]3^{2x-5}[/tex] = 9 , that is
[tex]3^{2x-5}[/tex] = 3²
Since the bases on both sides are equal, both 3 , then equate the exponents
2x - 5 = 2 ( add 5 to both sides )
2x = 7 ( divide both sides by 2 )
x = 3.5

Answer:
16.4
Step-by-step explanation:
The law of cosines is useful here. It tells you ...
b^2 = a^2 + c^2 -2ac·cos(B)
b^2 = 22^2 +10^2 -2·22·10·cos(44°)
b^2 ≈ 267.49
b ≈ √267.49 ≈ 16.35514
b ≈ 16.4

What is the surface area of the cylinder with height 3 cm and radius 6 cm? Round your to the nearest thousandth.
Answer:
113.097
Step-by-step explanation:
so Basically to find the area of this cylinder have to set up to equation ((2)6pi)3
first you multiply 2 x 6 getting you 12 then multiply it by pi which in mathematical terms is 37.7 multiplied by 3, getting you 113.097
which can be simplified to 113
The surface area of the cylinder with height 3 cm and radius 6 cm is 340 cm².
What is surface area?The surface area of a figure is the number of unit squares it takes to cover the entire surface without gaps or overlaps. If a three-dimensional figure has flat sides, the sides are called faces.
Given that, the cylinder with height 3 cm and radius 6 cm, we need to find its surface area,
SA of a cylinder = 2 π × radius × (height + radius)
= 2 × 3.14 × 6 × (3+6)
= 2 × 3.14 × 6 × 9
= 339.12
≈ 340
Hence, the surface area of the cylinder with height 3 cm and radius 6 cm is 340 cm².

express 148.502 in standard form
Pls as soon as possible
Answer:
1.48502 × 10²
Step-by-step explanation:
A number expressed in standard form is
a × [tex]10^{n}[/tex] ( 1 ≤ a < 10 and n is an integer )
Given
148.502 ← express as a number between 1 and 10
1.48502
To obtain the original number we require to multiply by 100 , that is 10²
Thus
148.502 = 1.48502 × 10²
Answer:
[tex]1.48502 \times {10}^{2} [/tex]
Step-by-step explanation:
To convert to standard form, move the decimal point until there is one digit to the left of the decimal point.
Since the decimal point moves to the left, the exponent value goes up. If the decimal point moves to the right, the exponent value gpes down.
In this case, since the decimal point moves to the left twice, then the exponent goes up by 2.
Hope this helps!

Answer:
The reason is likely because of an unit error of centimetres square (cm²) which is to be in metres square (m²)
Step-by-step explanation:
The units of the length is in meters, and the side length, S, of the cube is S = 0.7 m, therefore, the answer is to be given as follows;
The surface area of one face of the cube = S² = (0.7 m)² = 0.49 m²
The number of faces in a cube = 6, therefore, we have;
The surface area of the cube = 6 × The surface area of one face of the cube
The surface area of the cube = 6 × 0.49 m² = 2.94 m²
Therefore, the surface area of the cube is 2.94 m² (m² not cm²)

Answer:
The answer is 15.
Step-by-step explanation:
Plug in the numbers for the a and b values individually. For the numerator, 5(6) is the same thing as 5 * 6 = 30. For the denominator, 1/4^2 would equal to 1/16 and when you multiply it by 32, you will get 2.
To clear things up, the fraction should be 30/2 and your answer should be 15 as a result.

find the coordinates of the orthocenter for XYZ with X(-5,-1) Y(-2,4), Z(3,-1)
9514 1404 393
Answer:
(-2, 2)
Step-by-step explanation:
The orthocenter is the intersection of the altitudes. The altitude lines are not difficult to find here. Each is a line through the vertex that is perpendicular to the opposite side.
Side XZ is horizontal, so the altitude to that side is the vertical line through Y. The x-coordinate of Y is -2, so that altitude has equation ...
x = -2
__
Side YZ has a rise/run of -1/1 = -1, so the altitude to that side will be the line through X with a slope of -1/(-1) = 1. In point-slope form, the equation is ...
y -(-1) +(1)(x -(-5))
y = x +4 . . . . . . . . subtract 1 and simplify
The orthocenter is the point that satisfies both these equations. Using the first equation to substitute for x in the second, we have ...
y = (-2) +4 = 2
The orthocenter is (x, y) = (-2, 2).

Given
Given the polynomial
[tex]-m^6-10m^3[/tex]
To determine
The degree of the polynomial
In order to determine the degree of the polynomial, we need to check the term with the highest of the degree with non-zero coefficients. The degree of an individual term is basically the exponent of the term.
In our case,
The exponents of the terms of this polynomial are, in order, 6, and 3.
Thus, the highest degree (larger exponent) of the term is 6.
Therefore, we conclude that:
The degree of the polynomial is 6.Read again and write T (true ) or F (false

This one is very simple.
The triangle on the left has two equal sides, so the angle on the opposite side of that same triangle is also 52º. That angle is on a 180º line, so the angle right next to it has to be 180º - 52º, so 128º. The other two angles of that triangle are unknown, but still equal because of the sides being the same. So, subtract 128º from 180º to get 52º again, but divide it by two. The angle measurement of x = 26º

Sophie pays m dollars to rent a car for the weekend. On the drive home, she buys $25 worth of gasoline. Her friend Melody pays for one-half the cost of the car rental only. Choose an expression you could use to determine how much Sophie spent. A. m + 25 B. m + 25 –12 C. 12(m + 25) D. 12m + 25
Answer:
D. 1/2m + 25
Step-by-step explanation:
Sophie pays m dollars to rent a car for the weekend.
On the drive home, she buys $25 worth of gasoline.
From the above question, we are told that:
Her friend Melody pays for one-half the cost of the car rental only.
= m - 1/2m
= 1/2m
Hence, the cost of the rental that sophie is paying for is 1/2m dollars
She buys $25 of gasoline
Let the amount sophie spent be represented by A
The expression you could use to determine how much Sophie spent is given as:
A = 1/2m + 25

1/2 + 25

Step-by-step explanation:

12xy³z⁶/4x⁵yz¹²=3y²/x⁴z⁶
The division of (12xy³[tex]z^6[/tex])/ (4[tex]x^5[/tex]y[tex]z^{12[/tex]) is 3y²/ [tex]x^4[/tex][tex]z^6[/tex].
What is Polynomial?A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminates in mathematics.
Given:
(12xy³[tex]z^6[/tex])/ (4[tex]x^5[/tex]y[tex]z^{12[/tex])
Now, expand for the division
12/4= 3
x / [tex]x^5[/tex] = 1/ [tex]x^4[/tex]
y³ /y = y²
[tex]z^6[/tex] / [tex]z^{12[/tex]= 1/[tex]z^6[/tex]
So, the division is
(12xy³[tex]z^6[/tex])/ (4[tex]x^5[/tex]y[tex]z^{12[/tex])
= 3y²/ [tex]x^4[/tex][tex]z^6[/tex]

Explain the purpose of statements and reasons in a formal proof.
Answer:
Find the explanation below.
Step-by-step explanation:
Statements simply state the theorem that is to be proofed. Formal proof in logical sequence connects the hypotheses to the conclusion reached.
Statements and reasons are important because they help to breakdown a theorem, showing in steps and stages how a conclusion was reached. They provide facts that convince the observer that the theorem is indeed true.
