Answer: 50 km
Step-by-step explanation: So the map has a scale of 1 cm: 20 km. Next, you look at how far they are apart and see if the scale and the distance on the map are the same measurement. In this case, they are both centimeters so they stay the same. Then, all you do is multiple the real size, 20 km, by
2.5 /1 . Then, 20 x 2.5=50. So the answer is 50 km
What exactly am I doing wrong with the first one I’m doing the order of operation and I can get the second one no issues I can’t seem to figure out how to do the first one tho
Answer:
36
Step-by-step explanation:
(4+2)²
4+2=6
6²=36
Answer:
36
Step-by-step explanation:
So we have the expression:
[tex](4+2)^2[/tex]
Order of operations says: 1) Parentheses, 2) Exponents, 3) Multiplication/Division and 4) Addition/Subtraction.
So, add within the parentheses first:
[tex](4+2)^2\\=(6)^2[/tex]
Now square:
[tex]=36[/tex]
So our answer is 36.
Also, note that you apparently used the distribute property. The distribute property does not work with addition and exponents:
[tex](4+2)^2\neq4^2+2^2[/tex]
You cannot do this. This isn't correct. Instead, you must first add and then square.

Find the value of y for which the value of 1.7y+37 is 14 less than the value of 9.3y–25 HELP QUICK
Answer:
y=10
Step-by-step explanation:
1.7y+37 is 14 less than the value of 9.3y–25
1.7y + 37 = 9.3y - 25 - 141.7y + 37 = 9.3y - 399.3y - 1.7y = 37 + 397.6y = 76y = 76/7.6y = 10Answer is 10
Answer:
y=10
Step-by-step explanation:
10 x 1.7 = 17
17 + 34 = 51
10 x 9.3 = 93
93 - 25 = 51
Same answer, so y = 10
Write a polynomial that represents the area of the shaded region
Answer:
S = 1/2 . x^2 + 11/2 . x + 15
Step-by-step explanation:
- Let S = the area of the shaded region
- From the figure we see that S = 1/2 the area of the rectangle
- The area of the rectangle is (x+5)(x+6) = x^2 + 11x + 30
--> S = 1/2 (x^2 + 11x + 30)
--> S = 1/2 . x^2 + 11/2 . x + 15

Which of the following is closest to
0 on the number line?
A) - | -5.1 |
B) 4.7
C) - | - 0.9 | D) - | 6.7 |
Answer:
C
Let's simplify the answers. Use absolute value.
| -5.1 | = 5.1 - > |5.1| = 5.1
4.7 - > |4.7| = 4.7
| -0.9 | = 0.9 - > |0.9| = 0.9
- |6.7| = -6.7 - > |-6.7| = 6.7
Now, order each from least to greatest.
0.9, 4.7, 5.1, 6.7
Which one is the smallest? 0.9
So, C is correct.

Find a possible solution to the equation cos(x+2)= sin(3x)
Answer:
x = 22
Step-by-step explanation:
Let's say that a & b are complementary angles...
Then cos a = sin b
We can also write sin(3x) as ,
[tex] \sin(3x) = \cos(90 - 3x) [/tex]
Substituting the value of sin(3x) in the question ,
[tex] \cos(x + 2) = \cos(90 - 3x) [/tex]
Cancelling cos from both the sides gives us -
[tex]x + 2 = 90 - 3x\\ [/tex]
Solving this eqn , x = 22

Given:
Plan 1 = $30 per month unlimited calls
Plan 2 = $11 + $0.04(per call)
Find:
Number of monthly calls, plan 1 better than plan 2

Taila earns d dollars per week. How much does Taila earn in 10 weeks?
Answer:
[tex]10d[/tex] dollars
Step-by-step explanation:
[tex]d[/tex] is a variable, which is just a placeholder for an unknown value. Therefore, we can treat [tex]d[/tex] as if it's a number.
If you earn a certain amount of dollars per week, and you work for 10 weeks, then to find how much money you earn, you'd multiply the amount of weeks (10) by the dollars per week right?
Same logic applies for variables.
Since we have [tex]d[/tex] acting as a placeholder for the amount earned per week, then the total amount of money earned in 10 weeks is [tex]10\cdot d[/tex], which can just be represented as [tex]10d[/tex].

of equation 3x+5=0
Answer:
x=3/5
Step-by-step explanation:
3x+5=0
3x=-5
x=-5/3
Answer:
x = 5/3
Step-by-step explanation:
Given equation: 3x-5 = 0
Add both sides by 5, we get
= 3x - 5 + 5 = 0 + 5
= 3x = 5
Divide both sides by 3, we get
3x/3 = 5/3
or, 3x = 5
so, x = 5/3
Mr Chong intends to purchase a few chickens, rabbits and ducks for his farm. The total numbers of animal is 50. He has RM1500 to be spent. A chicken costs RM20, A rabbit RM50 and a duck RM30. The number of chickens is equal to the number of ducks. How many of each animals should Mr Chong purchase? Write a system of linear equations to solve this problem.
Answer:
20 chickens, 10 rabbits and 20 ducks
Step-by-step explanation:
Let chickens be c, rabbits be r, ducks be d
Chicken cost = RM20Rabbit cost = RM50Duck cost = RM30As per given we get below equations:
c + r + d = 50c = d20c + 50r + 30d = 1500Substitute d:
c + r + c= 50 ⇒ 2c + r = 50 20c + 50r + 30c = 1500 ⇒ 50c + 50r = 1500 ⇒ c + r = 30Subtract the second equation from the first one:
c = 20Then:
r = 10d = 20So animals bought:
20 chickens, 10 rabbits and 20 ducksWater flows through a pipe at a rate of 9 gallons every 8 minutes. Express this rate of flow in fluid ounces per hour.
Answer:
[tex]Rate = 8640 fl\ oz/hour[/tex]
Step-by-step explanation:
Given
Rate: 9 gallon in every 8 minutes
Required
Express in fluid ounces per hour
Express rate as follows;
[tex]Rate = \frac{9\ gallon}{8\ minutes}[/tex]
1 gallon = 128 fluid ounces;
So:
[tex]Rate = \frac{9 * 128 fl\ oz}{8\ minutes}[/tex]
1 minutes = 1/60 hour;
So:
[tex]Rate = \frac{9 * 128 fl\ oz}{8 * \frac{1}{60} hour}[/tex]
[tex]Rate = \frac{1152 fl\ oz}{ \frac{8}{60} hour}[/tex]
[tex]Rate = 1152\ fl\ oz/ \frac{8}{60}\ hour[/tex]
[tex]Rate = 1152* \frac{60}{8}\ fl\ oz/hour[/tex]
[tex]Rate = \frac{1152*60}{8}\ fl\ oz/hour[/tex]
[tex]Rate = \frac{69120}{8}\ fl\ oz/hour[/tex]
[tex]Rate = 8640 fl\ oz/hour[/tex]

2) You work in the tech field. Your boss has asked that you and your team design a new style phone with a 7" screen display. What are the dimensions of the phone if the aspect ratio is 16:9?
Answer:
dimensions of the phone are 7 inches x 12.44 inches
Step-by-step explanation:
The formula for the aspect ratio of a display device is a proportional relationship between the width and the height of the display.
That is;
Aspect ratio = height/width
Now, we are given;
Aspect ratio = 16:9 or 16/9
Width = 7" = 177.8 mm
Thus;
16/9 = height/177.8
Multiply both sides by 177.8 to give;
Height = (16 × 177.8)/9
Height = 316.089 mm
Converting 316.089 mm to inches gives us 12.44 inches.
Thus, dimensions of the phone are 7 inches x 12.44 inches
