Answer:
the speed is 20 m/s
Step-by-step explanation:
The computation of the speed is as follows
As we know that
Speed = Distance ÷ time
where,
Distance is 420 meters
And, the time is 21 seconds
So, the speed is
= 420 ÷ 21
= 20 m/s
hence, the speed is 20 m/s
We simply applied the above formula so that the correct value could come
And, the same is to be considered
The length between the bases on a baseball field is 90 feet. A scale drawing shows the distance between the bases as 2 inches. One inch on this drawing
equals how many feet?
Enter your response here:
Answer:
1 inch of drawing = 45 feet
Step-by-step explanation:
Given that:
Length between the bases on a baseball field = 90 feet
As per the scale drawing, the distance between the bases is equal to 2 inches.
To find:
Length of one inch on the drawing is equal to actual length of how many feet?
Solution:
First of all, let us learn about the scale drawings.
Scale drawings are a way to represent the big real world measurements on a paper.
Therefore, small measurements are used to represent the bigger real world measurements.
Here, it is given that:
2 inches on scale is equal to 90 feet of actual length.
Therefore,
1 inch on scale is equal to [tex]\frac{90}{2}[/tex] = 45 feet of actual length.
Therefore, 1 inch of drawing = 45 feet

Answer:
a) 1.24 g/ml
b) 2.4%
Step-by-step explanation:
density = mass/volume
volume of sample = 28.4 - 15 = 13.4mL
density = 13.4/10.8
=1.24 g/ml

Answer:
This is an percentage change question, by any chance you have a maths textbook, look for units that contains the topic: Percentage Change. Now, let's get solving! :)
Step-by-step explanation:
Firstly, you must multiply 4.5% with 56. That is: shipping fees x purchase price
That gives ($) 2.52 (this is your answer)
No addition/totaling needed as the question asked ONLY for the shipping fees.

The ratio of boys to girl in a school is 5:7 if there are 600 students, how many girls are there
Answer:
350 girls
Step-by-step explanation:
So,
The secret to solving problems with ratios is to find the value of one unit.
5:7 = 12 units total
To find one unit, divide the total number of students by the total number of units.
600/12 = a
Simplify
50/1 = a
50 = a
The value of each unit is 50.
Now, multiply the units by the numbers in the ratio.
50(5) = b
250 = boys
50(7) = x
350 = x
There are 350 girls.
Helppp find the solution to this equation 2x+4y=8. x=3y-6 What do x and y  equal
Answer:
y = 2, x = 0
Step-by-step explanation:
2x + 4y = 8
x = 3y - 6
2x + 4y = 8
2 ( 3y - 6 ) + 4y = 8
10y - 12 = 8
10y = 20
y = 2
x = 3y - 6
x = 3 ( 2 ) - 6

Gabriel is buying bagels for a family gathering. Each bagel costs $1.75. Answer the questions below regarding the relationship between the total cost and the number of bagels purchased.
The independent variable, x, represents the
, and the dependent variable is the
, because the
depends on the
.
A function relating these variables is N(x) =N(x)=
.
So N(14) =N(14)=
, meaning 1414
.
Answer:
Independent Variable: Number of bagels bought
Dependent Variable: Total cost because it depends on the number of bagels bought.
Function: N(x)=1.75x
So, if x is the number of bagels bought, N(14) means that 14 bagels were bought. So you multiply 14 by the price; 1.75. So, N(x)=1.75*14 = $24.5
Step-by-step explanation:
Answer:
The independent variable, x, represents the number of bagels purchased, and the dependent variable is the total cost of the bagels, because the total cost of the bagels depends on the number of bagels purchased.
A function relating these variables is V(x) =1.75x.
So V(14) = 24.5, meaning 14 bagels will cost 24.5 dollars.

=========================================================
Explanation:
Start at x = 3 on the x axis. Move up until you reach g(x), then move to the left to hit the y axis. You should arrive at y = 3.
That y value is the input to the f(x) function.
Plugging x = 3 into the f(x) function has us draw a vertical line down to f(x) and then go horizontally until we reach y = -2.

Write a system of equations to describe the situation below, solve using any method, and fill in the blanks. Norma is a salon owner. Yesterday, she did 1 haircut and colored the hair of 2 clients, charging a total of $217. Today, she did 2 haircuts and colored the hair of 1 client, charging a total of $155. How much does Norma charge for her services? PLEASE ANSWER
Answer:
Cost of haircut = $93
Cost of colouring hair = $31
Step-by-step explanation:
Let
Cost of haircut = x
Cost of colouring hair = y
The equations
x + 2y = 217 (1)
2x + y = 155 (2)
From (1)
x = 217 - 2y
Substitute x = 217 - 2y into (2)
2x + y = 155
2(217 - 2y) + y = 155
434 - 4y + y = 155
-3y = 155 - 434
-3y = -279
y = -279 / -3
= 93
y = $93
Substitute y = 93 into (1)
x + 2y = 217
x + 2(93) = 217
x + 186 = 217
x = 217 - 186
= 31
x = $31
Cost of haircut = $93
Cost of colouring hair = $31

A recipe requires 1 2/3 cups of sugar. If Mrs.Marina is going to make one and one half of the recipe, then how much sugar does she need
Mrs. Marina requires 5/2 or 2.5 cups of sugar to make one and one half of the recipe.
What is proportion ?
A proportion is an equation based on the equality of two ratios.
Here it is given that :
A recipe requires 1 (2/3) cups of sugar.
That is 1 recipe requires = 1(2/3) cups of sugars
= 5/3 cups of sugar
Now, Marina is going to make one and one half of the recipe and to find the sugar he needed we simply multiply 1(1/2) both the sides :
1 recipe requires = 5/3 cups of sugar
1(1/2) recipe requires = (5/3) x 1(1/2) cups of sugar
3/2 recipe requires = (5/3) x (3/2) cups of sugar
3/2 recipe requires = 5/2 cups of sugar or 2.5 cups of sugar.
Therefore, Mrs. Marina requires 5/2 or 2.5 cups of sugar to make one and one half of the recipe.

What is arithmetic Progression?The difference between every two subsequent words in a sequence is the same; this is known as an arithmetic progression (AP). An equation for the previous block of the AP may be derived from this kind of development. For instance, the sequence 2, 6, 10, 14,... is a mathematical progression (AP) because it fits a pattern where every other number is acquired by adding 4 to the respective period.
The given data is,
-10, 20, -40
From -10 to 20 it is multiplied by 2 with a positive sign, and from 20 to -40 it is multiplied by 2 with a negative sign. Similarly, the next two numbers are 80 and -160.

f(x)=-2x+3
g(x)=3x+3
find f(1-x) + g(1-x)
Answer:
-5x + 11
Step-by-step explanation:
All you're doing is substituting.
f(x)=-2x+3
f(1-x) = 2(1-x)+3
= 2 - 2x +3
= -2x + 5
g(x)=3x+3
g(1-x) = 3(1-x)+3
= 3 - 3x + 3
= -3x + 6
Now add them together and combine like terms:
f(1-x) + g(1-x)
-2x + 5 + -3x + 6
= -5x + 11

. A electric jug was sold allowing 20% discount
with Profit of Rs.120. If the jug was sold
allowing 30% discount, there would have
been loss of Rs. 270. Find the MP of the jug.
solu
9514 1404 393
Answer:
marked price = Rs. 3900
Step-by-step explanation:
The difference between the discounts is 30% -20% = 10% of the marked price. The difference in Rs is 120 -(-270) = 390. If Rs. 390 is 10% of the marked price, then the marked price is (Rs. 390)/(0.10) = Rs. 3900.
The marked price is Rs. 3900.
_____
Check
A 20% discount from 3900 is a price of 3120. If the profit is 120, the cost price is 3000. A 30% discount from 3900 is 2730. This is 270 below the 3000 cost price, so our answer is consistent with problem requirements.
As a reward for winning a math competition, 26 students in the 7th grade visited a theme park. On one ride, 3 equal groups of students could be seated and 2 students were left over. Write and solve an equation to find how many students could be seated in each group.
Answer: in each group, there are 8 students.
Step-by-step explanation:
We have a total of 26 students.
If we separate them into 3 equal groups (suppose that each group has X students) and leave 2 students left, we will have the relation:
3*X + 2 = 26
This means that 3 times the number of students in each group, plus the two students leftover must be equal to the initial number of students.
Now we can solve this for X.
3*X + 2 = 26
3*X = 26 - 2 = 24
X = 24/3 = 8
X = 8
This means that in each group there are 8 students.
