Answer:
4W + 4 = 6
W = 1/2
Step-by-step explanation:
4W + 4 = 6 See the comments below. Subtract 4 from both sides
4W = 6 - 4 Combine the terms.
4W = 2 Divide by 4. That tells you how much 1 W weighs
W = 2/4 On the right, you get 2/4
W = 1/2 Each w is 1/2
Explanation
There are 4 red objects. They all weigh the same amount. So that means that you have 4 W on one part of the scale. On the same side (the left side) there are 4 green weights. They all weigh one. 4*1 = 4 So the left side has 4W + 4 The right side his 6 one pound weights. 6 * 1 = 6The equation is 4w + 4 = 6The actual thickness of a machine part is 0.5 cm, and it has to be measured to within a 2% error. What is the largest measurement

Lydia buys 3 apples and 2 pears from a fruit stand and spends $3.85. The next week she goes back and buys 4 apples and 1 pear and spends $3.80. Which system of equations can be used to find the cost per apple, a, and the cost per pear, p?
Answer:p=0.72 a=0.77
Step-by-step explanation:
By using system of equations we get cost per apple is 0.75 and cost per pear is 0.8.
What are System of Equations?A system of equations is a collection of two or more equations with a same set of unknowns.
By given data we construct system of equations
3a+2p=3.85...(1)
4a+p=3.80...(2)
We have to solve the above equations ,
Multiply with 2 in second equation.
8a+2p=7.6
So Now subtract from 1
3a+2p-8a-2p=3.85-7.6
3a-8a=-3.75
-5a=-3.75
a=3.75/5
a=0.75
Now substitute value of a in 3a+2p=3.85
3(0.75)+2p=3.85
2.25+2p=3.85
2p=1.6
p=0.8
Therefore cost per apple is 0.75 and cost per pear is 0.8.

Step-by-step explanation:
The picture frame has a perimeter of 100 inches. The width is 22 inches. Calculate the missing length. Use that answer to find the area of the picture frame.
Length of frame?
Area of frame?
Answer:
39 inches.
858 inches²
Step-by-step explanation:
Length:- (if length = x)
2 ( 11 + x ) = 100
22 + 2x = 100
2x = 100 - 22
2x = 78
x = 78 ÷ 2
x = 39 inches
Area:-
Area = l × b
= 39 × 22
= 858 inches²

2. in a class of 50 students, the number of females is 2 more than 5 times the number of males. How many males and females are there in the class?
Answer:
The number of male students is 8, while the number of female students is 42.
Step-by-step explanation:
To determine the number of male and female students in the class, knowing that in total there are 50 students, and that the number of female students is two more than five times the number of male students, the following equation must be performed:
X + (5X + 2) = 50
6X + 2 = 50
6X = 50 - 2
X = 48/6
X = 8
Thus, the number of male students is 8, while the number of female students is 42.
a second truck arrives whose ladder, when extended,is 30 meters long. the base of this ladder is also 4 metres above the ground. for safety reasons, the max angle of elevation that the ladder can make is 70%
Answer: The maximum height of the wall that can be reached by the ladder on the second truck = 58.19 meters
Step-by-step explanation:
A diagram for the given situation is attached.
To find: AC
In right triangle ABF,
[tex]\dfrac{AB}{AE}=\sin 70^{\circ}\\\\\Rightarrow\ \dfrac{AB}{30}=0.9397\\\\\Rightarrow\ AB=30\times0.9397\approx 28.19[/tex]
Now AC = AB + BC = 28.19 + 30 meters = 58.19 meters
Therefore, the maximum height of the wall that can be reached by the ladder on the second truck = 58.19 meters

Jordan wants to buy a new car. He found a great car at a dealership for $18,000. The dealership offered him a compound interest rate of 3.5% for 60 months. How much will he be paying in interest only?
A-$3,150.00
B-$21,150.00
C-$3,378.35
D-$21,378.35
Answer:
$3,378.35
Step-by-step explanation
Before we can get the interest, we need to get the amount after 60 60months
A = P(1+r)^t
A = 18000(1+0.035)^5
A = 18000(1.035^5)
A = 18000(1.1877)
A = $21,378.35
Interest = Amount - Principal
Interest = 21,378.35- 18000
Interest = $3,378.35
Hence he will be paying $3,378.35 as interest
Find the unknown value in the proportion x∕32 = 38∕64.
Question 4 options:
A)
19
B)
38
C)
54
D)
76
Answer:
x=19
Step-by-step explanation:
This can be found in two ways.
Way #1
Since 32 is half of 64, divide 38 in half to get the missing number, or 19.
Way #2
Solve for x.
x/32 = 38/64
(Solve the expression on the right side)
x/32 = 0.59
(Multiply both sides by 32 to isolate the variable.)
x= 18.88 --> 19.
