Answer:
448
Step-by-step explanation:
This is a proportion question. Keep the heights on one side of the proportion and the shadow length on the other.
height ratio shadow ratio
40 cm / x = 25 / 280 Cross multiply
25x = 40 * 280 Combine
25x = 11200 Divide by 25
x = 11200/25
x = 448 cm
The height of the corn plant is 448 cm
Please solve this equation
Answer: Below
Step-by-step explanation:
Well they already gave you crucial information. The radius, or r, is 19, and pi can be substituted with 3. Using that we can do:
C = 2 * 3 * 19
C = 6 * 19
C = 114
Our answer is 114.

Carl or felipa ( I need a explanation aswell ) And I’ll give thanks and brainliest!!!!
Answer:
Carl is incorrect, he didn't write an equivalent expression and he didn't use the distributive property in the equation.
Step-by-step explanation:
When solving equations, we use PEMDAS
P = Parenthesis
E = Exponent
M = Multiply
D = Divide
A = Add
S = Subtract
So lets solve the equation then:
6 - 4 (3 - 6x) + 12x
Use the distributive property to multiply −4 by 3 and -6x
6 - 12 + 24x + 12x
Subtract 12 from 6 to get −6
-6 + 24x + 12x
Combine 24x and 12x to get 36x
-6 + 36x
So, -6 + 36x is the answer
And the reason why Felipa is correct, is because Felip wrote an equivalent expression, she correctly multiplied -4 (3 - 6x) before adding or subtracting and she combined like terms correctly.
The reason why Carl is incorrect, is because he didn't write an equivalent expression and he didn't use the distributive property in the equation.

Find a polynomial that represents the area of the
square.
Answer:
16x² + 72x + 81
Step-by-step explanation:
The area of a square is [tex]s^2[/tex], where s = side. In this case, we're given the side length as 4x + 9.
[tex](4x+9)^2 = (4x+9)(4x+9)[/tex] [tex](4x+9)(4x+9)=(4x)(4x)+(4x)(9)+(9)(4x)+(9)(9)[/tex] [tex]16x^2+36x+36x+81[/tex] [tex]16x^2+72x+81[/tex]Therefore, the answer is 16x² + 72x + 81.
Solve for each equation 3 1/4 = 1/2 + w
Answer:
w = - [tex]\frac{58}{31}[/tex]
Step-by-step explanation:
3 1/4 = 1/2 + w
Cross Multiply
31(2 + w) = 4
Divide both sides by 31
[tex]\frac{31(2 + w)}{31}[/tex] = [tex]\frac{4}{31}[/tex] (simplify) -> 2 + w = [tex]\frac{4}{31}[/tex]
Subtract 2 from both sides
2 + w - 2 + [tex]\frac{4}{31}[/tex] - 2 (simplify) -> - [tex]\frac{58}{31}[/tex]
w = - [tex]\frac{58}{31}[/tex]

Step-by-step explanation:
(3)
the values of q decrease as the values of p increase.
this indicates an inverse relationship between the quantities, that is
q = [tex]\frac{k}{p}[/tex] ← k is the constant of variation
to find k use any ordered pair from the table.
using q = 16 when p = 3 , then
16 = [tex]\frac{k}{3}[/tex] ( multiply both sides by 3 )
48 = k
q = [tex]\frac{48}{p}[/tex] ← equation of variation
(4)
the values of q increase as the values of p increase.
this indicates the quantities are in direct variation, that is
q = kp ← k is the constant of variation.
to find k use any ordered pair from the table.
using q = 2 when p = 6 , then
2 = 6k ( divide both sides by 6 )
[tex]\frac{2}{6}[/tex] = k , that is
k = [tex]\frac{1}{3}[/tex]
q = [tex]\frac{1}{3}[/tex] p ← equation of variation

One just needs to go to his/her calculator and solve it
Answer:
0.04566210...(8-digit repeat)
Step-by-step explanation:
The quotient of 6 ÷ 131.4 is shown in the attachment. The remainder at the bottom matches the original dividend, so the quotient will be repeating:
[tex]\dfrac{6}{131.4}=0.\overline{04566210}[/tex]
The division process starts by rewriting the problem to integer division:
60/1314
(If you like, you could further reduce this to 10/219 by removing a common factor of 6 from numerator and denominator.)
At each stage, the quotient digit is multiplied by the divisor and the result subtracted from the dividend to get a new dividend. Careful attention to the vertical alignment of digits will help ensure that quotient digits have their proper place value.

Find the value of x if the perimeter is 30. X+3, x, 2x-1
Step-by-step explanation:
Perimeter represents the sum of all of the sides adding.
The problem is stating that;
[tex]30 = x + x + 3 + 2x - 1[/tex]
Combine like terms;
[tex]30 = 4x + 2[/tex]
Subtract from both sides;
[tex]28 = 4x[/tex]
Divide each side by 4;
[tex]7= x[/tex]
Check;
[tex]30 = 7 + 7 + 3 + 2(7) - 1[/tex]
[tex]30 = 17 + 14 - 1[/tex]
[tex]30 = 31 - 1[/tex]
[tex]30 = 30\checkmark[/tex]
(–2) + (–20) step by step
Answer:
-22
Step-by-step explanation:
Step 1: Subtract 20 from -2
(-2) + (-20) is the same thing as -2 - 20When subtracting a negative value from a negative number, you keep the negative sign and just add the two numbers.- 2 - 20 = -22Therefore, the answer is -22.

Answer:

geometry due tonight
Answer:
A: 5 CM
B: 2.5 CM
C: ABC approx. equal to EDC (I'm not 100% sure on this one, but it makes most sense.)
I can't help you with number four, I'm sorry. I hope someone else comes along and helps with that!
Step-by-step explanation:
The symbol being used means "approximate equality" meaning that the two angels are alike. So in A, the two sides on the shapes are both 5 cm. On B, since it is half of that side, it would be half of five, making it 2.5 cm. For C, the middle letter is the one touched second. Therefore when you draw the shape it makes the most sense that it's ABC approx. equal to EDC. Not to mention that ABC and the next angel has to match, so since the C is last, it also matches in that spectrum.
For D, I don't know the terminology, I'm sorry.
a: b = 7:4
b: c= 2:5

In a direct variation, y=8 when x=2. Write a direct variation equation that shows the relationship between x and y.
Answer:
y=4x
Step-by-step explanation:
Direct Variation means y=kx where k is a Constant
since y=8 when x=2
y=kx --> 8=k*2 then k=4
Then y=4x

We are given both of those measurements so all we need to do is put them in the formula
[tex]32*40=1280[/tex]
What is solving inequalities
An inequality is a comparison of expressions by either "less than" (<), "less than or equal to" (<=), "greater than" (>), or "greater than or equal to" (>=). Note that Html does not support the standard symbols for "less than or equal to" and "greater than or equal to", so we use <= and >= for these relations.

Answer: 5
Step-by-step explanation:
Find the equation of the line that is parallel to the line y = 2x – 2 and passes through the point (5, -1). Write the equation in point- slope form.
Solution:
We know that:
Equation of parallel line: y = 2x - 2Since the parallel line has a slope of 2, the equation of the original line will also have a slope of 2. Now, let's use point-slope form to find the equation.
y - y₁ = m(x - x₁)y - (-1) = 2(x - 5)y + 1 = 2(x - 5)Thus, the equation of the line in point slope form is y + 1 = 2(x - 5).
