What is the base 2 representation of 129?
Assuming 129 is given in base 10, notice that
129 = 128 + 1 = 2⁷ + 1
More clearly, we have
129 = 1•2⁷ + 0•2⁶ + 0•2⁵ + 0•2⁴ + 0•2³ + 0•2² + 0•2¹ + 1•2⁰
so that
129 = 1000 0001₂

x/4 + y/5 = 2 and x/2 + y = - 3. Solve for x and y
Answer:
A) x/4 + y/5 = 2
B) x/2 + y = - 3
Step-by-step explanation:
We multiply A) by -4 and B) by 2
A) -x - 4/5 y = -8
B) x + 2y = -6 then add A) and B)
1.2y = -14
y = 11 (2/3) = -11.6666666...
x + 2y = -6
x = -6 -2*-11.6666666
x = -23.3333332
The formula for the speed of a tsunami in deep water is v=gh−−√ , where g is acceleration due to gravity, 9.8 m/s2 , and h is the depth of the ocean in meters. Use this formula to estimate the speed at which the tsunami that started with an earthquake in Sumatra struck Sri Lanka about 1550 km away. The Bay of Bengal is 4 km (4000 m) deep.
Answer:
v = 200 m/s
Step-by-step explanation:
The formula for the speed of a tsunami in deep water is given by :
[tex]v=\sqrt{gh}[/tex]
Here,
g is acceleration due to gravity
h is the depth of the ocean in meters.
We need to find the speed at which the tsunami that started with an earthquake in Sumatra struck Sri Lanka about 1550 km away. The Bay of Bengal is 4 km (4000 m) deep.
It means we need to find v if h = 4000 m
So,
[tex]v=\sqrt{10\times 4000}\\\\v=200\ m/s[/tex]
So, the speed of the tsunami is 200 m/s.
Which equation has a solution of x = 9? A. 5x=45 B. 2x=20 C. 4+x=12 D. x+7=26
Answer:

The cuboid has volume 288cm^3 (a) the cuboid has a length 12 cm and a width 5cm Calculate the height of the cuboid (b) 1cm^3 of the cuboid has a mass of 4g Work out the mass of the cuboid. Please help I am desperate
Answer:
height= 4.8cm
Step-by-step explanation:
volume= length×width× height given the volume and length and width, 288=12×5×h
288=60h
divide both sides by 60
h=4.8cm
h = 4,8 cm
m = 1152 g
Step-by-step explanation:V = l×w×h
h = V/l×w
= 288cm³/12cm×5cm
= 288cm³/60cm²
= 4,8 cm
1cm³ .............. 4g
288cm³ ........ xg
x = 288cm³×4g/1cm³ = 1152 g

Answer:
Commutative property of multiplication
Step-by-step explanation:
This property states that numbers can be switched around when multiplying and the answer still remains the same
Answer:
C
Step-by-step explanation:
So we have the expression:
[tex]63\cdot 3[/tex]
And Jared rewrote it as:
[tex]3\cdot 63[/tex]
In other words, he just switched the order and the expression remains equivalent.
This is an example of the commutative property of multiplication, which states that if you change the order of a multiplication sentence, the sentence will remain equivalent.
So, our answer is C.

Maggie’s brother is 3 years younger than four times her age the sum of their ages is 27
well i think maggie would be 6
Step-by-step explanation:
6•3=18
18-4=14
14+6=20
Answer:
[tex]\huge\boxed{\text{Maggie = 6 years, Brother = 21 years}}[/tex]
Step-by-step explanation:
We can create two equations based on the word problems, where [tex]m[/tex] is Maggie's age and [tex]b[/tex] is her brother's age.
[tex]m + b = 27[/tex]
[tex]b = 4m - 3[/tex]
We can now substitute [tex]4m-3[/tex] in as [tex]b[/tex] into [tex]m+b=27[/tex].
[tex]m + (4m-3) = 27\\\\5m - 3 = 27\\\\5m = 30\\\\m = 6[/tex]
Now that we know the value of [tex]m[/tex], we can substitute it into [tex]m+b=27[/tex].
[tex]6 + b = 27\\\\b = 27-6\\\\b = 21[/tex]

h(n)=4n+ 4 find h (-3)
Step-by-step explanation:
h(n)=4n+ 4 find h (-3)
h(-3)=4(-3)+4
=-12+4
=--8
Answer: -8
Step-by-step explanation: h(n) = 4n + 4 means that
if we put an n into our function, a 4n + 4 comes out.
So here, we're putting a -3 into our function which means that
a 4(-3) + 4 comes out which simplifies to -12 + 4 or -8.
So h(-3) = -8 or the value of the function at -3 equals -8.

Step-by-step explanation:
10. Three kinds of teas are worth $4.60 per pound, $5.75 per pound, and $6.50 per pound. They are to be
mixed together to get 20 pounds of tea worth $5.25 per pound. The amount of $4.60 tea used is to be equal
to the amount of the other two teas combined. How many pounds of each tea should be used?
Answer:
The mass of the $4.60/lb tea that should be used in the mixture is 10 lb
The mass of the $5.75/lb tea that should be used in the mixture is 8 lb
The mass of the $6.50/lb tea that should be used in the mixture is 2 lb
Step-by-step explanation:
The parameters of the question are;
The worth of the three teas are
Tea A = $4.60/lb
Tea B = $5.75/lb
Tea C = $6.50/lb
The mass of the mixture of the three teas = 20 lb
The worth of the mixture of the three teas = $5.25 per pound = $5.25/lb
The amount of the $4.60 in the mixture = The sum of the amount of the other two teas
Therefore, given that the mass of the mixture = 20 lb, we have in the mixture;
The mass of tea A + The mass of Tea B + The mass of Tea C = 20 lb
The mass of tea A = The mass of Tea B + The mass of Tea C
Therefore;
The mass of tea A + The mass of tea A = 20 lb
2 × The mass of tea A in the mixture = 20 lb
The mass of tea A in the mixture = 20 lb/2 = 10 lb
The mass of tea A in the mixture = 10 lb
The mass of Tea B + The mass of Tea C = The mass of tea A = 10 lb
The mass of Tea B + The mass of Tea C = 10 lb
The mass of Tea B = 10 lb - The mass of Tea C
Where the mass of Tea C in the mixture = x, we have;
The mass of Tea B in the mixture = 10 lb - x
The cost of the 10 lb of tea A = 10 × $4.60 = $46.0
The worth of the tea mixture = 20 × $5.25 = $105
The worth of the remaining 10 lb of the mixture comprising of tea A and tea B is given as follows;
The worth of Tea B + The worth of Tea C in the mixture = $105.00 - $46.00 = $59.00
Therefore, we have;
x lb × $6.50/lb + (10 - x) lb × $5.75/lb = $59.00
x × $6.50 - x × $5.75 + $57.50 = $59.00
x × $0.75 = $59.00 - $57.50 = $1.50
x = $1.50/$0.75 = 2 lb
∴ The mass of Tea C in the mixture = 2 lb
The mass of Tea B in the mixture = 10 lb - x = 10 lb - 2 lb = 8 lb
The mass of Tea B in the mixture = 8 lb
Therefore, since we have;
Tea A = $4.60/lb
Tea B = $5.75/lb
Tea C = $6.50/lb
The mass of tea A in the mixture = 10 lb
The mass of tea B in the mixture = 8 lb
The mass of tea C in the mixture = 2 lb, we find;
The mass of the $4.60/lb tea that should be used in the mixture = 10 lb
The mass of the $5.75/lb tea that should be used in the mixture = 8 lb
The mass of the $6.50/lb tea that should be used in the mixture = 2 lb.

In how many ways can the letters in the word spoon be arranged?
24
30
60
120
Explanation:
There are 5 letters, so there would be 5! = 5*4*3*2*1 = 120 different permutations; however, there are 2 letter 'o's meaning we have double counted. To correct this, divide by 2 to get 120/2 = 60.
If there was a way to tell the two 'o's apart, then the answer would be 120.
The total number of ways the letter in the word "spoon" can be arranged is 120 and this can be determined by using the given data.
Given :
Word -- Spoon
The following steps can be used in order to determine the total number of ways the letter in the word spoon is arranged:
Step 1 - According to the given data, the word is 'spoon'.
Step 2 - The total number of letters in the word 'spoon' is 5.
Step 3 - So, the total number of ways the letter in the word "spoon" can be arranged is:
[tex]= 5 \times 4\times 3\times 2 \times 1[/tex]
Step 4 - Simplify the above expression.
= 120

x ( > or = ) 5/9
Step-by-step explanation:
● 2(1 + x) ( > or = ) 11 - 3x
● 2 + 2x ( > or = ) 11 - 3x
Add 3x to both sides
● 2 + 2x + 3x ( > or = ) 11 - 3x + 3x
● 2 + 5x (> or = ) 11
Substract 2 from both sides
● 2 + 5x -2 ( > or = ) 11 -2
● 5x (> or =) 9
Divide both sides by 5
● 5x/5 ( > or = ) 5/9
● x ( > or = ) 5/9
