Answer:
Jami has $13.5
Mami has $18.5
Step-by-step explanation:
Let j = Jami's money
m - Mami's money
j + m = 32
j = m - 5 (Since Jami basically has 5 less than Mami)
Substitute the j in the top equation
m - 5 + m = 32
2m - 5 = 32
Add 5 to both sides
2m - 5 = 32
2m = 37
Divide both sides by 2
2m/2 = 37/2
m = 37/2 = 18.5
Now plug the new m into the bottom equation
j = 18.5 - 5
j = 13.5
does anyone know the answer?
Answer:
Part A: 9.75x > 195
Part B: x > 20
Step-by-step explanation:
Let's say Mark works for x hours. For each hour he works, 9.75 dollars are added to Mark's salary. Therefore, for 1 hour, he gets $9.75, for 2 hours, he gets $9.75 + $9.75 = $9.75 * 2 = $19.50, and for x hours, he gets $9.75 * x as his salary.
We want his salary to be more than $195, so we have $9.75 * x (his salary) > $195, which can be written as 9.75x > 195
divide both sides by 9.75 to solve for x
x > 20

What is the volume of this sphere?
Use a = 3.14 and round your answer to the nearest hundredth.
2 in
Answer:
33.49 cubic inches
Step-by-step explanation:
the volume of a sphere is represented by (4/3)pi(r)^3
pi is 3.14 and r is 2
so 4/3(3.14)(2^3)
2^3 is also 8
4/3(3.14)(8)
the final answer is 33.4933333
OR when rounded it is 33.49
Statement:
The radius of the sphere is 2 inches.
To find out:
The volume of the sphere.
Solution:
Radius (r) = 2 inπ we have to consider as 3.14.We know, volume of a sphere [tex] = \frac{4}{3} \pi \: {r}^{3} [/tex]Therefore, the volume of the sphere[tex] = \frac{4}{3} \times 3.14 \times {(2)}^{3} \: \: cubic \: \: inches \\ = \frac{4}{3} \times 3.14 \times 8 \: \: cubic \: \: inches \\ = 33.49 \: \: cubic \: \: inches[/tex]
Answer:
The volume of the sphere is 33.49 cubic inches.

HELP PLEASE! whats the height and base??
Answer: 7.5
Step-by-step explanation:
Area of the bottom left triangle = 4x3/2 = 6
Bottom right = 6x3/2 = 9
Top right = 3x4/2 = 6
Top left = 6x3/2 = 9
6+9+6+9 = 30
Each square unit is 4
So the answer should be 30/4 = 7.5
Hope this is correct
Seth and Ted can paint a room in 6 hours if they work together. If Ted were to work by himself, it would take him 1 hours longer than it would take Seth working by himself. How long would it take Seth to paint the room by himself if Ted calls in sick
Answer:
11.5 hours
Step-by-step explanation:
It would take Seith x hours to paint the room by himself, then Ted needs x + 1 hour.
During 1 hour, Seith can do 1/x of the work, Ted can do 1/(x+1) of the work, then we have
1/x + 1/(x + 1) = 1/6
(2x + 1)/[x(x+1)] = 1/6
x(x+1)=6(2x+1)
x^2 + x = 12x + 6
x^2 - 11x - 6 = 0
[tex]x=\frac{11+\sqrt{145}}{2}= 11.5 hours[/tex]

Find the Least Common Denominator. Then, express each fraction using the Least Common Denominator.
7/10 and 5/6
Answer:
LCM of 7/10- 70
LCM of 5/6- 30
Step-by-step explanation:
Solution:
To find the Least common denominator (LCD) of 7/10 and 5/6, we need to find the Least common multiple of 10 and 6.
I found the LCM through division method. Refer to image attached~
We can tell that:
The LCM is 2 x 3 x 5, which when simplified, we obtain 30. The LCD is 30.Now, let's multiply the denominators and the numerators such that 30 is the denominator in both fractions.
=> 7/10 = 7 x 3/10 x 3 = 21/30=> 5/6 = 5 x 5/6 x 5 = 25/30The fractions are:
21/30 and 25/30Javier is standing near a tree. He holds an electronic tape measure near his eyes and finds the three distances shoen
The radius of circular pipe is 12cm,what length of tape is required to wrap once around the pipe(use pie =3.14)
Answer:
75.36 cm
Step-by-step explanation:
We need to find the circumference of the pipe.
Circumference of a circle = 2[tex]\pi[/tex]r (where r is the radius)
Given:
r = 12 cm[tex]\pi[/tex] = 3.14⇒ circumference = 2 x 3.14 x 12 = 75.36 cm

Answer: Yes, because the amount of money you save for every beverage bought is constant, and if you buy 0 beverages, you’ll save $0. That means it the situation is graphed, the line produced will be linear and crosses through the origin, which are the requirements for a proportional relationship.
height of trapezium if the area given is 124
Short base: 12 cm
Long base: 19 cm
Height:?
Answer:
A= 0.5 x (a+b) x h
124 = 0.5 x (12+19) x h
124 = 15.5 x h
÷15.5
h = 8cm
0.5x(12+19) x 8 does gives 124
Thus, height is 8cm.

Write the trinomial as a square of a binomial or as an expression opposite to a square of a binomial: -1 + 4a -4a^2
Answer:
-(1 - 2a)^2
Step-by-step explanation:
-1 + 4a - 4a^2
= -[1^2 - 2*1*(2a) + (2a)^2]
= -(1 - 2a)^2
Answer:
Step-by-step explanation:
Begin by taking out the minus
-(4a^2 - 4a + 1) The answer is the square root of the 1st and 3rd terms.
√4a^2 = 2a
√1 = 1 Since middle term is minus, one of 2a or 1 must also be minus
Usually the one is made minus.
That leaves you with a perfect square
- (2a - 1)^2 There are more ways than 1 to write this, but I think this is the clearest answer
Question is in the image

3,100 x 1/10 what is the value of the expression?
Answer: 310
Step-by-step explanation:
Multiplying a value by 1/10 is the same as dividing by 10.
Therefore, 3100* 1/10 = 3100/10
3100/10 = 310.
Hey there!
3,100 × 1/10
= 3,100/1 × 1/10
= 3,100(1) / 1(10)
= 3,100 / 10
= 3,100 ÷ 10 / 10 ÷ 10
= 310 / 1
= 310 ÷ 1
= 310
Therefore, your answer is: 310

For each line, determine whether the slope is positive, negative, zero, or undefined.
Answer:
1. Undefined
2. Negative
3. Zero
4. Positive
Step-by-step explanation:
1. Undefined, the line moves in both directions vertically. It's impossible to tell what the slope is.
2. Negative, the line is decreasing at a constant rate, the slope is negative.
3. Zero, the line doesn't increase or decrease, therefore the slope is 0. (No changes)
4. Positive, the line is increasing at a large rate, the slope is positive.

Sum of two numbers 80 and difference is 40. Find two
numbers.
Answer:
The two numbers are 20 and 60
Step-by-step explanation:
Two numbers: x and y
x + y = 80
x - y = 40
x = y + 40
Substitute x
y + 40 + y = 80
2y + 40 = 80
2y = 40
y = 20
Substitute y, so x = 60
