HELP!!! Last month, there were 4 sunny days for every rainy day. If there were 30 days in the month, how many days were rainy? Explain your reasoning. If you get stuck, consider using a tape diagram.
Answer:
6
Step-by-step explanation:
Based on the ratio of sunny days to rainy days last month, there would have been 6 rainy days.
For every 4 sunny days, there is 1 rainy day. This means that every 5 days, one of those days will be rainy and 4 will be sunny.
We can therefore represent that as:
= 1/5 of any number of days will be rainy
If there are 30 days therefore, 1/5 of those 30 days will be rainy:
= 1/5 x 30
= 6 days
In conclusion, 6 days will be rainy out of 30 days.

is the equation y=1/5x+2 is changed to y=1/5x-4, how will graph the line change
Answer:
The answer to this problem is:
It will shift down 6 units
Step-by-step explanation:
not only have the y-intercept(s) change but also where they are positioned, this is shown in the graphs below.
The graph of the line will shift down by 6 units when the equation y = 1/5x + 2 is changed to y = 1/5x - 4 (option b).
To compare the two equations, y = (1/5)x + 2 and y = (1/5)x - 4, we can focus on their y-intercepts. The y-intercept of the first equation is 2, and the y-intercept of the second equation is -4.
When the y-intercept changes from 2 to -4, the graph will shift vertically. The y-coordinate is decreasing from 2 to -4, which means the graph will shift down by 6 units.
Therefore, the correct answer is:
B) It will shift down 6 units.

Find the area of the given figure.
Answer:
not enough information
answers to unit 1 geometry basics homework 4 angle addition postulate
Answer:
EF = 58
Step-by-step explanation:
Find the diagram of the question attached.
According to the addition postulate;
DE+EF = DF
Given
DE = 47
EF = 3x+10
DF = 9x-39
Substitute into the addition postulate formula and get x
47+3x+10= 9x-39
Collect like terms
3x-9x = -39-10-47
-6x = -96
x = -96/-6
x = 16
Next is to evaluate EF:
EF = 3x+10
EF = 3(16)+10
EF = 48+10
EF = 58
Hence the measure of EF is 58
question: What is the slope of the line?
Answer:
4/5
Step-by-step explanation:
If you look at the point (-2,0) you can see that it sits directly on the line above 2. If you also at the point (3,4) you can see that its also sitting directly in the middle, where the line runs through it. Using this information we can use Rise/Run.
Rise/Run = Y/X
from (-2, 0) you rise 4 and you run 5 to the right to land on (3,4).
This is one of many ways you can calculate The slope from a graph!

∴ Fraction = x/y = 3/8
Hope It Helps!Answer: 3/8
Step-by-step explanation:
Let x represent the numerator and y represent the denominator.
Equation 1: (4x)/(y - 2) = 2
4x = 2(y - 2) Cross Multiplied
4x = 2y - 4 Distributed
4x - 2y = -4 Subtracted 2y from both sides
Equation 2: (x + 15)/(2y - 2) = 9/7
9(2y - 2) = 7(x+15) Cross Multiplied
18y - 18 = 7x + 105 Distributed
-7x + 18y - 18 = 105 Subtracted 7x from both sides
-7x + 18y = 123 Added 18 to both sides
Solve the system of equations using Elimination Method:
EQ1: 4x - 2y = -4 → 9(4x - 2y = -4) → 36x - 18y = -36
EQ2: -7x + 18y = 123 → 1(-7x + 18y = 123) → -7x + 18y = 123
29x = 87
÷29 ÷29
x = 3
Substitute x = 3 into either equation to solve for y:
EQ1: 4x - 2y = -4
4(3) - 2y = -4
12 - 2y = -4
-2y = -16
y = 8
The numerator (x) = 3
The denominator (y) = 8
The fraction is: 3/8

In ΔRST, the measure of ∠T=90°, the measure of ∠S=75°, and ST = 97 feet. Find the length of TR to the nearest tenth of a foot.
9514 1404 393
Answer:
TR = 362.0 ft
Step-by-step explanation:
The tangent relation is useful for this.
Tan = Opposite/Adjacent
tan(75°) = TR/ST = TR/(97 ft)
TR = (97 ft)(tan(75°))
TR ≈ 362.0 ft

1 ≤ x + 7 < 7
explain how u got the answer plz
Answer:
-6 ≤ x < 0
Step-by-step explanation:
Subtract the 7 on both sides to get x isolated.
Answer:
-6 ≤ x < 0
Step-by-step explanation:
This is the answer because:
1) First, we have to isolate the x
2) In order to isolate the x, you have to subtract 7 from 1 and 7
1 - 7 = -6
7 - 7 = 0
Therefore, the inequality is -6 ≤ x < 0

Fernando evaluated the expression below. StartFraction 5 (9 minus 5) over 2 EndFraction + (negative 2) (negative 5) + (negative 3) squared = StartFraction 5 (4) over 2 EndFraction minus 10 + 9 = StartFraction 20 over 2 EndFraction minus 10 + 9 = 10 minus 10 + 9 = 9. What was Fernando's error?
Answer:
Fernando incorrectly found the product of –2 and –5.
Step-by-step explanation:
Fernando evaluated the numerator of the fraction incorrectly.
Fernando simplified StartFraction 20 over 2 EndFraction incorrectly.
Fernando incorrectly found the product of –2 and –5.
Fernando evaluated (negative 3) squared incorrectly.
Fernando's calculation
5(9-5) / 2 + (-2)(-5) + (-3)^2
= 5(4) / 2 - 10 + 9
= 20/2 - 10 + 9
= 10 - 10 + 9
= 9
Correct calculation
5(9-5) / 2 + (-2)(-5) + (-3)^2
= 5(4) / 2 + (10) + 9
= 20/2 + 10 + 9
= 10 + 10 + 9
= 29
Therefore,
Fernando's error was multiplying (-2)(-5) to be equal to -10 instead of 10
Fernando incorrectly found the product of –2 and –5.

Maria cut 3/4 yard of ribbon into pieces that are 1/8 yard long. How many pieces of ribbon did Maria cut? don't be a b.*.t.c.h. and not solve it
===============================================
Explanation:
3/4 = 6/8 after multiplying top and bottom of the fraction by 2
She has 6/8 of a yard of ribbon.
If she cuts the ribbon into pieces of 1/8 of a yard each, then she has 6 pieces overall
We can see this if we solve the equation (1/8)x = 6/8. Multiply both sides by 8 to get x = 6.
The number of pieces of ribbon that Maria cut is 6 pieces.
Given,
Maria cut 3/4 yards of ribbon into pieces that are 1/8 yard long.
We need to find how many pieces of ribbon Maria cut.
How do we divide two fractions?We multiply one fraction with the reciprocal of the other fraction.
Example:
a/b ÷ c/d
= a/b x d/c
= ad/bc
We have,
The total length of the ribbon = 3/4 yards
The length of each piece cut from the ribbon = 1/8 yards.
The number of pieces that can be cut:
= 3/4 ÷ 1/8
= 3/4 x 8/1
= 3x8 / 4x1
= 24 / 4
= 6
Thus the number of pieces of ribbon that Maria cut is 6 pieces.
