h) There are 5 significant numbers in 0.0087600
i) There are 3 significant numbers in 0.00202
Step-by-step explanation:
How many significant figures are in each of these numbers?
a) 768
There is no decimal so, all digits are significant numbers.
There are 3 significant numbers in 768
b) 0.000086
There is decimal point in this number. Zero's on leading (right) side of the number are not considered significant. Only non-zero values are considered significant.
So, There are 2 significant numbers in 0.000086
c) 8.0
There is decimal point in this number. Digits on left side and right side of the decimal are considered significant
So, There are 2 significant numbers in 8.0
d) 43,000
There is no decimal so, all digits are significant numbers.
There are 5 significant numbers in 43,000
e) 3.0200x10^6
It can be written as: 3.0200000000
There is decimal point in this number. Digits on left side and right side of the decimal are considered significant
So, There are 11 significant numbers in 3.0200x10^6
f) 7.9800
There is decimal point in this number. Digits on left side and right side of the decimal are considered significant
So, There are 5 significant numbers in 7.9800
g) 98.0010
There is decimal point in this number. Digits on left side and right side of the decimal are considered significant
So, There are 6 significant numbers in 98.0010
h) 0.0087600
There is decimal point in this number. Zero's on leading (right) side of the number are not considered significant. Only non-zero values are considered significant.
So, There are 5 significant numbers in 0.0087600
i) 0.00202
There is decimal point in this number. Zero's on leading (right) side of the number are not considered significant. Only non-zero values are considered significant.
So, There are 3 significant numbers in 0.00202

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.

C.is decrease by 1 foot every 500 miles D. Is decrease by 1 foot every 1000 miles
Answer:
Option A
Step-by-step explanation:
Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Line shown in the graph is passing through two points (2, 8000) and (4, 7000).
Therefore, slope of the given line = [tex]\frac{8000-7000}{2-4}[/tex]
= -500 feet per mile
Which means, altitude decreases by 500 ft every mile.
(Negative sign represents the decrease)
Option A is the correct option.

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

One leg of a right triangle measures 10 inches while the other leg measure square root of 21 inches. What is the length of its hypotenuse?
Answer:
11 inches
Step-by-step explanation:
hypotenuse² = leg₁² + leg₂²
=10² + (√21)²
= 100 + 21
= 121
Hypotenuse = √ 121 = √11*11 = 11 inches
Answer:
10^2+√21^2= 100+21= 121
square root of 121= 11
Answer is 11 inches

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.

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 = 6describe how to solve -5x=30
Answer:
x = -6
Step-by-step explanation:
30 = -5x
30/-5 = -5x/-5
-6 = x
Divide 30 by -5 to solve for x
Answer:
Divide both sides by -5.
x = 30/-5 = -6
x = -6
