30x times 1/2= 15x
30 times -2 = -60
40y times 3/4= 30y
40 times -4= -160
add like terms so -60 + -160 = -220
so it's 15x +30y -220

[tex]\frac{1}{7}[/tex]
Step-by-step explanation:
Given
tanx = [tex]\frac{3}{4}[/tex] = [tex]\frac{opposite}{adjacent}[/tex]
This is a 3- 4- 5 right triangle with hypotenuse = 5, then
cosx = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{4}{5}[/tex]
sinx = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{3}{5}[/tex]
Then
[tex]\frac{cosx-sinx}{cosx+sinx}[/tex]
= [tex]\frac{\frac{4}{5}-\frac{3}{5} }{\frac{4}{5}+\frac{3}{5} }[/tex]
= [tex]\frac{\frac{1}{5} }{\frac{7}{5} }[/tex]
= [tex]\frac{1}{5}[/tex] × [tex]\frac{5}{7}[/tex]
= [tex]\frac{1}{7}[/tex]

will a 13 inch rusty metal bar fit into a box (rectangular prism) with dimensions 9 inches by 8 inches by 3 inches?
Answers
Answer:
Bar will not fit in the box.
Step-by-step explanation:
Given:
Length = 9 in
Width = 8 in
Height = 3 in
Length of bar = 13 in
Find:
Bar fit in box or not
Computation:
If length of bar is equal to length of diagonal than it will fit in box.
Diagonal of a cuboid = √l² + b² + h²
Diagonal of a cuboid = √9² + 8² + 3²
Diagonal of a cuboid = √81 + 64 + 9
Diagonal of a cuboid = √154
Diagonal of a cuboid = 12.40 in
Diagonal of a cuboid < Length of bar
So,
Bar will not fit in the box.

What is the theoretical probability of rolling a number lower than 7 on a fair number die
Answers
Explanation:
Rolling a number less than 7 is guaranteed to happen since all of the outcomes {1,2,3,4,5,6} are all less than 7. So we have a 100% probability here.
The number 100% converts to the decimal 1.00 or just 1 for short.

Step-by-step explanation:
Let Tom alone take 2x days
Peter alone will take x days
Together in 1 day they do 1/x + 1/2x = 1/16
3/2x = 1/16
2x = 48

Answers
Answer: z=116 x= 50 1/3
Step-by-step explanation:
64 degrees corresponds to the angle on top of angle z. That means the angle on top of z is also 64 degrees. This same angle and angle z are a linear pair; they sum to 180. 64+z= 180. Subtract 64 from both sides. Z= 116. Angle z and angle (3x-35) are also a linear pair and sum to 180. We know z is 64, so 64+(3x-35) = 180. Combine like terms. 29+3x = 180. Subtract 29 from both sides. 3x = 151. Divide both sides by 3. X= 50 1/3
a) Jelaskan konsep Alam Melayu.
Answers
Answer: The Malay world or Malay realm, is a concept or an expression that has been utilised by different authors and groups over time to denote several different notions, derived from varied interpretations of Malayness, either as a racial category, as a linguistic group or as a political-cultural group. The use of the term 'Malay' in much of the conceptualisation is largely based on the prevalent Malay cultural influence, manifested in particular through the spread of the Malay language in Southeast Asia as observed by different colonial powers during the Age of Discovery.

Monday, February 15th, looks to be the coldest day of 2021 so far. The day starts out at 2° and warms up 9° more by noon. It warms another 2° before dropping quickly 17° by midnight. What would the temperature be at midnight? Explain your thinking. Part 2: How many degrees would the temperature need to rise after midnight to be above freezing? Explain your thinking.
Answers
Answer:
The temperature is of -4º at midnight.
The temperature has to rise by more than 4º after midnight to be above freezing.
Step-by-step explanation:
The day starts out at 2° and warms up 9° more by noon.
So temperature of 2 + 9 = 11º at noon.
It warms another 2° before dropping quickly 17° by midnight.
The temperature after midnight is of:
11º + 2º - 17º = 13º - 17º = -4º.
The temperature is of -4º at midnight.
How many degrees would the temperature need to rise after midnight to be above freezing?
Add x, has to be higher than 0. So
-4º + x > 0º
x > 4º
The temperature has to rise by more than 4º after midnight to be above freezing

Name a possible value for w that is a solution to w > 30, but is not a solution to w < 70.
PLZ HELP RN
Answers
=============================================================
Explanation:
This value of w is larger than 30, so it makes w > 30 true.
At the same time, this value of w is not smaller than 70, so it makes w < 70 false.
If a value of w makes an inequality true, then we consider it a solution.
Put another way: if w = 100, then w > 30 becomes 100 > 30 which is true while w < 70 becomes 100 < 70 which is false.
You can pick any value you want for the answer as long as it's 70 or larger. We can pick w = 70 because w < 70 becomes 70 < 70 which is false. A number cannot be smaller than itself.
In terms of the graph, you can pick any value that is to the right of 70 or at the location of 70.

Answer:
We know
y = 3.5x represents the cost of x pounds of raisins.
Also, cranberries costs $18 per 4 pounds
So, to graph these proportions, we have to find the equation for cranberries, if 4 pounds costs $18, that means 1 pound of cranberries is $4.50, this is the ratio of change of cranberries, using this ratio, we can say that the relation is
y = 4.5x
If you compare, cranberries are more expensive than raisins, the image attached shows both proportion graphed.
Therefore, raisins represent the lower unit price, $3.50 per pound, while cranberries represent the higher unit price, $4.50 per pound.
Answer :
well one line takes the slope of y=3.5x
The cranberries take the slope of Y=4.5x
so raisins have the lowest unit price.
