Step-by-step explanation:
A bag of rice lasted 7 days for 77 children how long will it last for 11 children
1 day
You have to divide 77 to 7. It will be 11. That's why its 1 day...
3. What is the equation in slope intercept
form of the line that passes through the
point (2,-2) and is perpendicular to the
line y =2/5x+2
A.
y= 2/5x - 7
B.
y=-2/5x+7
C.
y=5/2x-3
D.
y=-5/2x+3
Answer:
A
Step-by-step explanation:
If you plug in (2, -2) to each one, you would get -2= 5/2(2)-7
5/2 = 2.5 and 2.5 x 2 = 5, 5-7 does in fact equal the Y which is -2

Given h(x) = 5x + 2, find h(-6).
What is the slope of the line graphed on the coordinate plane?
Put your answer in the box
Answer:
-8
Step-by-step explanation:
As we know, slope is rise over run. We count up and over until we get to the next dot. To get to the next dot, we count 8 up and -1 over (since we go to the left, not the right). We can put this in a fraction (rise/run). That gets us 8/-1, which can be simplified to -8.

Please correct me if I am wrong
Step-by-step explanation:
You have to apply the rule alogc (b) (b^a)
= [tex]\frac{log10(\sqrt{8))^{4}-log10((\frac{1}{2}))^{3}) } }{3-6log10(\sqrt{5}) }[/tex]
\frac{\log _{10}\left(\frac{\left(\sqrt{8}\right)^4}{\left(\frac{1}{2}\right)^3}\right)}{3-6\log _{10}\left(\sqrt{5}\right)}
Susan is making a large batch of salsa.
She can spend no more than $30 on ingredients. She buys all ingredients except for tomatoes for $6.50. Tomatoes cost $2 per pound.
How many pounds of tomatoes,x, can she buy?
INEQUALITY THAT REPRESENTS THIS SITUATION
30>= 6.50+2x
Answer:
She can buy 0 to 11.75 pounds of tomatoes.
Step-by-step explanation:
Consider the provided information.
It is given that Susan can spend no more than $30 on ingredients. She buys all ingredients except for tomatoes for $6.50. Tomatoes cost $2 per pound.
It means she can only spend less than or equal to $30. Let x be the pounds of tomatoes she can buy.
So, the required inequality should be:
[tex]30\leq 6.50+2x[/tex]
Now simplify the inequality.
[tex]30-6.50\leq 2x[/tex]
[tex]23.5 \leq 2x[/tex]
[tex]11.75\leq x[/tex]
Hence, she can buy 0 to 11.75 pounds of tomatoes.
Find the perimeter of a 35° slice of pizza that has a radius of 8 inches.
9514 1404 393
Answer:
20.9 inches
Step-by-step explanation:
The perimeter length is the sum of the lengths of the two straight edges and that of the curved edge.
P = r + r + rα . . . . . where α is the central angle in radians
35° is (35°/180°)π radians, about 0.6109 radians
Then the perimeter is ...
P = r(2 +α) = (8 in)(2 +0.6109) ≈ 20.9 in
The perimeter of the slice is about 20.9 inches.
Choose the best method to solve the system of linear equations. Then choose a reason to justify your answer choice. x−3y=6 x−3y=−3
Answer:
No solution.
Step-by-step explanation:
The given equations are :
x−3y=6 ...(1)
x−3y=−3 ...(2)
We need to solve the above equations.
The above two lines are parallel. Forparallel lines,
[tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}\ne \dfrac{c_1}{c_2}[/tex]
Here,
[tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}[/tex]
It means, the above equations have no solution.
Which sentence best describes the equation: z = 18 + 96
Answer:
A
Step-by-step explanation:
Z is the same as the answer to the equation so if you add 18 and 96 together you will get z
also sum means adding
Answer: a
Step-by-step explanation:
the answer has addition and it says 18+96=z so i believe that theyre trying to say that whatever you add is gonna equal z so i believe the correct answer is a (:
Factor the expression.

O A
(4x + 7)(4x - 7)
B. (7x + 4)(7x-4)
C. (7x-4)(7x-4)
OD. (4x-7)(4x - 7)
Step-by-step explanation:
Difference of squares: A² - B² = (A + B)(A - B).
Therefore 49x² - 16 = (7x)² - (4)² = (7x + 4)(7x - 4).
The correct answer is Option B.
3. Angle g and angle h are:
A. adjacent
B. congruent
C. complementary
D. vertical
Answer: Adjacent angle you can look it up you know that right
Noah ran 2 1/2 miles in 3/5 hour. How far does he run in 1 hour?
Step-by-step explanation:
0.6 hours = 2.5 miles
=> 1 hour = 2.5 miles * (1/0.6) = 4.16 miles.
Hence Noan runs 4.16 miles in 1 hour.
(or 25/6 miles)
The graphs of the equations 4x - y = 6 and x + y = 4 intersect at

Z + y + 0 = z + y equals to what?
Answer:
y=0/0
Step-by-step explanation:
Step 1: Add -y to both sides.
y+z+−y=y+z+−y
z=z
Step 2: Add -z to both sides.
z+−z=z+−z
0=0
Step 3: Divide both sides by 0.
0/0=0/0
y=0/0
Joe is arranging video games on shelves. He has 48 playstation games and 36 xbox games, Each shelf will have the same number of playstation and xbox games. If Joe must place all of the videogames on shelves, what are the possible number of shelves Joe will use?
Answer:
2 shelves
3 shelves
4 shelves
6 shelves
12 shelves
Step-by-step explanation:
playstation games = 48
xbox games = 36
Each shelf will have the same number of playstation and xbox games.
Find the common multiples of 48 and 36
48 = 2, 3, 4, 6, 8, 12, 16, 24, 48
36 = 2, 3, 4, 6, 9, 12, 18, 36
The common multiples are 2, 3, 4, 6, and 12
Therefore, the possible number of shelves Joe will use is
2 shelves
3 shelves
4 shelves
6 shelves
12 shelves

State if the three numbers can be the measures of the sides of a triangle. Show your work
1) 7,2,6
2) 11,2,11
Answer: 2
Step-by-step explanation:
Please give me the correct answer
Answer:
it's answer is 3.75
Step-by-step explanation:
Hypotenuse (h) = 6.25
Perpendicular (p) = 5
base (b) = ?
By using Pythagoras theorem we get
b = √ ( h² - p²)
= √( 6.25)² - 5²
= √ 14.0625
= √(3.75)²
= 3.75
Hope it will help:)❤
By Pythagoras theorem, a^2+b^2=c^2
The answer is 3.75
