Step-by-step explanation:
100 / 2 (1500/5 (6 + (21 + 7 - 24)))
= 100 / 2 (1500/5 (6 + (28 - 24)))
= 100 / 2 (1500/5 (6 + (4)))
= 100 / 2 (1500/5 (10))
= 100 / 2 (300 (10))
= 100 / 2 (3000)
= 50 (3000)
= 150000
Rule: BODMAS (Brackets first so if there's bracket in bracket solve the bracket in the brackets first)
if left + - x /, solve x and / first from left to right then when there's + - left solve everything from left to right

A baseball is hit from home plate at an initial velocity of 32 feet per second from a height of 5.5 feet. How long will it take for the ball to descend to an outfielder's glove 6 feet off the ground?
Answer:
t=0.19
Step-by-step explanation:
Velocity is distance per tine
V=s/t
32=5.5/t
t= 0.72
To know How long will it take for the ball to descend to an outfielder's glove 6 feet off the ground?
V=s/t
32=6/t
t=0.19

There are 35 students in a drama club two out of every five boys in the club are boys how much diamonds in the club are boys
Given:
Number of students = 35
Two out of every five boys in the club are boys.
To find:
The number of students in the club that are boys.
Solution:
Two out of every five boys in the club are boys. It means, the ratio of boys to the total number of student is 2:5.
Let the number of boys be 2x and number of students be 5x.
According to the question,
[tex]5x=35[/tex]
[tex]x=7[/tex]
Now, the number of boys is
[tex]2x=2(7)[/tex]
[tex]2x=14[/tex]
Therefore, 14 students in the club are boys.
how many liters are in 21 cups? if 1L=4.2cups
i don't understand how to do it
Answer:
5 L
Step-by-step explanation:
As given in question,
1 L can fill 4.2 cups.
So, 1 cup can hold [tex]\frac{1}{4.2}[/tex] L of fluid.
Therefore,
21 cups can hold = [tex]\frac{1}{4.2}[/tex] × 21
= 5 L
So, there is 5 L of fluid in 21 cups.

When two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent. G-CO.10 2. In triangle ABC, ∠ = ∠ = . Which of these can be proved using the triangle s
Answer:
The correct option is;
D. When two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent
Step-by-step explanation:
In the proof to show that the sum of the angles in a triangle = 180°, we have;
For a triangle located between two parallel lines, such that the base of the triangle coincides with one of the parallel lines, we have;
The angle formed by one of the base angles and the adjacent side of the extension = 180° by the sum of angles on a straight line
From the attached diagram of a triangle between two parallel lines, we have;
∠e + ∠b = 180° by the sum of angles on a straight line postulate
∠e = ∠a + ∠d by alternate interior angles postulate
∠c = ∠d by alternate interior angles postulate
∴ ∠e = ∠a + ∠c by substitution property
∴ ∠e + ∠b = ∠a + ∠c + ∠b = 180° by substitution property
Therefore, the sum of the interior angles of a triangle, ∠a + ∠c + ∠b = 180°.

PLEASE FAST!!: (math related, view picture) Liner equation: y= 3x-4
Somebody please draw/show how they did the map so i can do it. i need help!!
Answer:
Step-by-step explanation:
y = 3x - 4
x = 0, y = 3*0 - 4
y = -4
(0 , -4)
x = 1 , y = 3*1 - 4
y = 3 - 4
y = -1
(1 , -1)
x = 2 , y = 3*2 - 4
y = 6 - 4
y = 2
(2 , 2)
Now mark these points (0 , -4) , (1 , -1) & (2 , 2) in the graph and join the points

Help me with this please.. but when you do please explain what proportional relationships please!
Answer:
x column- 1.25, 7.5, 45.
y column- 5, 30, 180.
Step-by-step explanation:
Okay, to start off, we need to find how 1.25 got to 5. If we divide it, we get 4. So we go to 7.5 and multiply it by 4, since that seems to be the relationship between x and y. 7.5x4=30, which is an answer. So the second spot in the y column is where 30 goes. Now we figure out the relationship between the two numbers in the x column so we can figure out the missing one. When you divide 7.5 by 1.25, you get 6. So, if 1.25x6 makes the next number in the x column, 7.5x6 should make the missing number. 7.5x6 is 45, so the missing number in the x column is 45. Now we go back and multiply 45 by 4, which gets us 180.
What is the Slope of this equation?
y=-6/5x-5
Answer:
Slope = - 6/5
Step-by-step explanation:
Step 1:
y = mx + b Slope Intercept Form
Step 2:
m = Slope
Step 3:
y = - 6/5x - 5 Equation
Answer:
Slope = - 6/5
Hope This Helps :)
Answer:
m=-6/5; the slope is -6/5
Step-by-step explanation:
Here is an easy way to define slope:
y=mx+b
m is slope and b is the y-intercept
Remember, you just have to find what is multiplied by x in a slope-intercept equation, and that is the slope.

A restaurant uses 3 3 pounds of pasta for a party of 14 14 people. If they are cooking pasta for a party of 56 56 people, what should they do? CLEAR CHECK Use 42 42 more pounds of pasta. Use twice as much pasta. Use 12 12 more pounds of pasta. Use 4 4 times as much pas
Answer:
Use 12 more pounds of pasta.
Step-by-step explanation:
A restaurant uses 3 pounds of pasta for a party of 14 people. If they are cooking pasta for a party of 56 people, what should they do?
Hence, we have:
14 people = 3 pounds of pasta
56 people = x
Cross Multiply
14 × x = 56 × 3
14x = 56 × 3
x = 56 × 3/14
x = 12 pounds of pasta
Hence, if they are cooking for 56 people they should use 12 pounds of pasta

write an exponential function in the form y=ab^(x) that goes through points (0,4) and (6, 2916)
Answer:
y=4(3)^x
Step-by-step explanation:
The exponential function, that goes through points (0,4) and (6, 2916) is y = 4(3)ˣ
What is the exponential function?An exponential function is a mathematical function used to calculate the exponential growth or decay of a given set of data.
Given that, a graph of an exponential function is passing through, (0,4) and (6, 2916)
The exponential form of an equation is given by =
y = abˣ
Where, a is the y-intercept,
a = 4 here,
y = 4bˣ
Now substitute 6 for x and 2916 for y,
2916 = 4(b)⁶
b⁶ = 729
b = 3
Therefore,
y = 4(3)ˣ
Hence, the exponential function, that goes through points (0,4) and (6, 2916) is y = 4(3)ˣ
