Can some one help me with Freshmen Algebra I kinda forgot how to do something and I need a refresher.
Answer:
Wheres the question?
Step-by-step explanation:
Equivalent ratios are ratios that contain different numbers but express the same relationship between the quantities they're comparing. Ratios are equivalent if there's a positive number that can be multiplied by both quantities in one ratio to get the corresponding quantities in the second ratio. For example, imagine you're making hot sauce that calls for chile peppers and tomatoes in a ratio of 1:2. If you put in 1 chili pepper, you'll need to put in 2 tomatoes. If you put in 2 chili peppers, you'll need to put in 4 tomatoes to keep the ratio the same. You can multiply both numbers in the first ratio by 2 to get the corresponding numbers in the second ratio: 1 × 2 = 2 2 × 2 = 4 The ratios show the same relationship between chili peppers and tomatoes. Which of these ratios is equivalent to 2:3? A 2:6 B 4:6 C 3:2 D 3:4
Answer:
B 4:6
Step-by-step explanation:
Which of these ratios is equivalent to 2:3?
2 : 3 = 2/3
Check all that applies
A 2:6
= 2/6
= 1/3
= 1 : 3
B 4:6
= 4/6
= 2/3
= 2 : 3
C 3:2
= 3/2
= 3 : 2
D 3:4
= 3/4
= 3 : 4
The correct answer is B 4 : 6

A rectangular monitor’s size is measured diagonally from 1 corner to the opposite corner. What is the size of a rectangular monitor that is 30 centimeters wide by 24 centimeters high, to the nearest centimeter?
Answer:
38cm
Step-by-step explanation:
Using the Pythagorean Theorem, it is found that the size of the monitor is of 38 centimetres.
------------------------
In a right triangle with legs [tex]l_1[/tex] and [tex]l_2[/tex] and hypotenuse h, these measures are related by the Pythagorean Theorem, given by:
[tex]h^2 = l_1^2 + l_2^2[/tex]
In this problem:
The diagonal of the rectangle, which is the size of the monitor, is the hypotenuse.The width of [tex]w = 30[/tex] and the length of [tex]l = 24[/tex] are the legs, thus:[tex]s^2 = l^2 + w^2[/tex]
[tex]s^2 = 24^2 + 30^2[/tex]
[tex]s = \sqrt{24^2 + 30^2}[/tex]
[tex]s = 38[/tex]
The size of the monitor is of 38 centimetres.

Consider the equation below.
log.(x+3) = log2 (2+x)
Which system of equations can represent the equation?
Answer:
Option (1)
Step-by-step explanation:
[tex]\text{log}_4(x + 3)=\text{log}_2(2 + x)[/tex]
[tex]\text{log}_4(x + 3)=\frac{\text{log}_{10}(x+3)}{\text{log}_{10}4}[/tex]
[tex]\text{log}_2(2 + x)=\frac{\text{log}_{10}(2+x)}{\text{log}_{10}2}[/tex]
System of equations can be written as,
[tex]y_1=\text{log}_4(x + 3)=\frac{\text{log}_{10}(x+3)}{\text{log}_{10}4}[/tex]
[tex]y_2=\text{log}_2(2 + x)=\frac{\text{log}_{10}(2+x)}{\text{log}_{10}2}[/tex]
Therefore, system of equations given in Option (1) is the correct option.

Annika sells 6 inch pies for $5.00 and 8 inch pies for $9.00 each. Last week she sold twice as many 6 inch pies as she did 8 inch pies. She made $133.00 from her sales. Annika defined x as the number of 6 inch pies she sold and y as the number of 8 inch pies she sold. She wrote the system below.
6 x + 8 y = 133. 2 x = y.
Which statements about the system are true? Check all that apply.
Since the cost for each pie is $5 and $9, the first equation should be 5 x + 9 y = 133.
Since the 8 inch pies are 2 inches larger, the second equation should be x + 2 = y.
Since there are fewer 8 inch pies, the second equation should be x = 2 y to balance the values.
The first equation is correct because 6x represents the money earned for 6 inch pies and 8y represents the money earned for 8 inch pies.
The second equation is correct because there are more 6 inch pies and 2 times a number is always more.
Answer:
See below!
Step-by-step explanation:
Only the first choice is accurate.
The second choice is incorrect since it doesn't accurately represent the situation described.
The third choice is incorrect since it also doesn't accurately represent the situation described.
The fourth choice is incorrect since the equation is meant to show the cost of the pies, not the size.
While the fifth choice is correct in that the second equation is accurate, the reasoning is inaccurate.

Heng was trying to factor 10x^2+5x. She found that the greatest common factor of these terms was 5x5x5, x and made an area model:
Answer:
[tex]Width = 5x + 1[/tex]
Step-by-step explanation:
Given
[tex]Area = 10x^2 + 5x[/tex]
[tex]Length = 5x[/tex]
Required (Missing)
Determine the Width?
Area is calculated as:
[tex]Area = Length * Width[/tex]
Substitute values for Area and Length
[tex]10x^2 + 5x = 5x * Width[/tex]
Factorize the right hand side
[tex]5x(5x + 1) = 5x * Width[/tex]
Divide both sides by 5x
[tex]5x + 1 = Width[/tex]
Hence, the width of the model is 5x + 1

If PQR = STU, find the measure of each part.
R

59°
P
7 m
g

T
U
The answer is below
Step-by-step explanation:
Two triangles are said to be congruent if for the two triangles all the three sides are equal and all the three angles are equal to each other.
Given that ΔPQR is congruent to ΔSTU, hence all corresponding sides and corresponding angles are equal to each other.
∠P = ∠S = 59°
∠S + ∠T + ∠U = 180° (sum of angles in a triangle)
59 + 75 + ∠U = 180°
134 + ∠U = 180°
∠U = 46°
∠U = ∠R = 46°
∠Q = ∠T = 75°
Also, for the sides:
ST = PQ = 7 m
SU = PR = 8 m
