A metal bar has a mass of 960g and a volume of 120cm³. Find the density of the metal in the bar.
Answer:
Density = 8g/cm³
Step-by-step explanation:
Density = Mass/Volume
Given the following
Mass = 960g
Volume = 120cm^3
Substitute
Density = 960g/120cm^3
Density = 8g/cm³

Answer:
Step-by-step explanation:
1/11 = 0.09090909
2/9 = .2222222222
1/10 is certainly between these two numbers.
1/10 is 0.1 which is larger (just) than 1/11 but a good deal smaller than 2/9
1/20 = 0.05 which is just bigger than 1/11 but much smaller than 2/9. There are many numbers that would fit between 1/11 and 2/9

Nolan and Mia work at a dry cleaners ironing shirts. Nolan can iron 25 shirts per hour, and Mia can iron 35 shirts per hour. Mia worked twice as many hours as Nolan and they ironed 380 shirts between them. Determine the number of hours Nolan worked and the number of hours Mia worked.
Answer: Nolan worked 4 hours, and Mia worked 8 hours
Step-by-step explanation:
Step-by-step explanation:
Let x represent the number of hours Nolan worked.
Let y represent the number of hours Mia worked.
Mia worked twice as many hours as Nolan. This means that
y = 2x
Nolan can iron 25 shirts per hour, and Mia can iron 35 shirts per hour. Together, Nolan and Mia ironed 380 shirts between them. This means that
25x + 35y = 380 - - - - - - - - - - - - - -1
Substituting y = 2x into equation 1, it becomes
25x + 35 × 2x = 380
25x + 70x = 380
95x = 380
x = 380/95
x = 4
y = 2x = 2 × 4
y = 8
-5 | 6n +15 | +2 = - 43
Answer:
n=-1 or n=-4
Step-by-step explanation:
-5/6n + 15/ = -45
/6n + 15/ = 9
square both sides to neutralize absolute value
/6n + 15/^2 = 81
36n^2 + 180n + 225 = 81
divide both sides by 9
4n^2 + 20n + 25 = 9
4n^2 + 20n + 16 = 0
divide both sides by 4
n^2 + 5n + 4 = 0
Factorize
(n + 1)(n + 4) = 0
therefore n = -1 or -4
Which is the following functions is graphed below?
Answer:
A.y=|x|+7
Step-by-step explanation:
Find the linear function for F in terms of H
Answer:
F = -20h + 450
Step-by-step explanation:
To find the linear function, we will use the coordinate points (1, 430) and (2, 410)
Get the slope;
m = ΔF/Δh = 410-430/2-1
m = -20/1
m = -20
Get the y intercept b
Substitute m = -20 and (1, 430) into y = mx+b
430 = -20(1) + b
430+20 = b
450 = b
Swap
b = 450
Get the required equation
y = -20x + 450
replace x with h and y with F
F = -20h + 450
Hence the required equation is F = -20h + 450
A dog walks due east 180 ft to a corner.
After turning through an angle of 81.5°,
the dog walks 329 ft. to the second
corner. Then the dog walks back
to the starting point.
What is the area of the triangle
formed by his path?
Area = [?] ft.2
Round to the nearest hundredth.
Answer:
Area = 29284.87 ft²
Step-by-step explanation:
I've drawn a triangle to depict the movement of the dog with the angle and dimensions.
From the attached triangle, we see that the starting point is C, the first point is A and the second point is B.
Let's find the third side from the image using law of cosine.
Thus;
b² = a² + c² - 2ac cos B
Thus;
b² = 180² + 329² - 2(180 × 329)cos 81.5
b² = 32400 + 108241 - 17506.55
b² = 123134.45
b = √123134.45
b = 350.91 ft
We calculate the area of the triangle using heron's formula.
Area = √(p(p − a)(p − b)(p − c))
Where p = (a + b + c)/2 = (180 + 350.91 + 329)/2 = 429.955 ft
Area = √(429.955(429.955 - 180)(429.955 - 350.91)(429.955 - 329)
Area = 29284.886 ft²
To the nearest Hundredth gives;
Area = 29284.87 ft²
Answer:
29284.76

Hi I need help with this hope someone has the answer.A triangular window is above the door to a café. The length of the base of the window is 12 feet, and the height is 10 feet
What is the area of the window?
Answer:
the answer is 60
Step-by-step explanation:
12×10=120
120÷2=60
Step-by-step explanation:
Sample Response: The height of the triangle will be twice the height of the rectangle. The area of a triangle is ½ bh and the area of a rectangle is bh. If the bases are the same, then the height of the triangle has to be double that of the rectangle in order to get the same area.
Which property is demonstrated below?
a + b = b + a
Answer:
Commutative Property
Step-by-step explanation:
The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is "a + b = b + a"; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is "ab = ba"; in numbers, this means 2×3 = 3×2.
Answer:
Commutative property of addition

find the domain and range of relation of 3x + y =3
Rewrite the equation in the slope-intercept form.
3x + y = 3
Subtracting -3x from both sides we get this:
y = -3x + 3
This is just a straight line.
Here, x can be any real number.
When x is any real number, the value of y is also any real number.
A straight line goes on forever in two directions. It really does not matter what number we select for x to find y.
Answer:
Domain is ALL REAL NUMBERS.
Range is ALL REAL NUMBERS.
Your math book may write the answer in interval notation:
Domain is (-00, 00); Range is (-00, 00).
Note:
-00 means negative infinity.
00 means positive infinity.
Still in some math books, the author(s) may decide to use set notation to express ALL REAL NUMBERS for the domain and range.
If so, we can also write the answer this way:
Domain = {x| x = ALL R}, where big R stands for real numbers.
Range = {y| y = ALL R}, where big R stands for real numbers.

Sadiq measured the dimensions of a 1 kg bag of sugar and found the length was 9.2 cm, the width was 6 cm and the height was 14.1 cm.
Calculate the density of the sugar in g/cm3
Answer:
[tex]d=1.28\times 10^{-6}\ g/cm^3[/tex]
Step-by-step explanation:
The mass of a bag of sugar, m = 1 kg = 0.001 g
Length of bag, l = 9.2 cm
Width of bag, b = 6 cm
Height of the bag, h = 14.1 cm
We need to find the density of the sugar bag.
Density = mass/volume
So,
[tex]d=\dfrac{0.001\ g}{9.2\times 6\times 14.1\ cm^3}\\\\d=1.28\times 10^{-6}\ g/cm^3[/tex]
So, the density of the bag is [tex]1.28\times 10^{-6}\ g/cm^3[/tex].

Which of these is equivalent to 2.75?
A. 2 3/4
B. 2 2/5
C. 2 1/5
D. 2 3/25
Answer:
2 3/4
Step-by-step explanation:

Given:
A figure of a circle. A secant and tangent of the given circle.
To find:
The correct equation.
Solution:
According the intersecting tangent secant theorem, the square of tangent is equal to the property of external segment of secant and the measure of the secant.
Using intersecting tangent secant theorem, we get
[tex]6^2=x(x+5)[/tex]
It can be written as
[tex]x(x+5)=6^2[/tex]
The required equation is [tex]x(x+5)=6^2[/tex].
Therefore, the correct option is B.

Answer:
−4+2+10
Step-by-step explanation:
First we add the numbers with no variable or exponent:
−2++3−5+7+4
−2++10−5+4
Then we combine the like terms. When combining like terms, you must find the numbers with the same variable/letter and add them. A number with the variable cannot be added with the variable . They must be the same variable. Now let's combine the like terms in this problem.
−2++10−5+4
^ As you can see, the variable does not have a coefficient, so we just use the number 1 as a coefficient. If a variable doesn't have a coefficient, always use 1.
−2−4+10+4
Now we combine the other like terms.
−2−4+10+4
2−4+10
And last, we rearrange the numbers.
To rearrange the numbers, you have to start with the numbers with variables. You must start with the variable that comes first in the alphabet. Then we add the number with no coefficient, just a number by itself. If there's ever an exponent, add the coefficient with an exponent first in the answer.
−4+2+10
Hope this helps! ;)
