Jeffrey typed 110 words in 2 3 /4 minutes. At this rate, how many words can he type in 4 1/4 minutes?
Answer:
First, you have to find out the words per second.
2 and 3/5 min = 165 sec
165 sec divided by 110 words = 0.6 words a second
4 and 1/4 min = 255 sec
0.6 x 255 = 153 words in 4 and 1/4 min

[tex] - 2 \sqrt{7} [/tex]
Answer:
A. -2[tex]\sqrt{7}[/tex]
Step-by-step explanation:
3 - 5 = -2
The [tex]\sqrt{7}[/tex] is just like an x variable at this point because they are both the same. If it was [tex]\sqrt{7}[/tex] and [tex]\sqrt{14}[/tex] for example, then you wouldn't be able to subtract them so easily. Kinda like how you can't subtract 3x-5y because they're two different variables.

3. Andrea is buying snacks at the basketball game. The snacks are $2.25 apiece. She wants to buy 4
snacks. Would the ordered pair (4,9.25) be a solution to this problem? Explain why or why not.
If this is not a solution, provide the correct solution for an x-value of 4.
a) Yes
b) No, the ordered pair (9,4) is a solution to this problem.
c) No, the ordered pair (4, 1.77) is a solution to this problem
d) No, the Ordered pair (4,9) is a solution to this problem.
Answer:
D - No, the ordered pair (4,9) is a solution to this problem.
Step-by-step explanation:
If you plotted the number of snacks as the x-axis, and then the total cost of the snacks on the y-axis, you would be able to graph a line and see the cost of snacks based on the number purchased. If you were going to write an equation for this, it would be y=2.25x (or y = 2 1/4 x)
In this case, as each snack is the same price, the y-values for each x would be as such: (1, 2.25) <- one snack, $2.25;
(2, 4.5)
(3, 6.75)
(4, 9)
So that is why the ordered pair of (4,9) would be a solution to this problem.
Hope that makes sense!

can u answer this now please its urgent i only got 2 mars how do i get the other 2 marks and the bottom bit of the question got me 2 marks thew top bit didnt get me anything
Answer:
x = 11 / x = - 4
Step-by-step explanation:
x² - 7x - 34 = 10
x² - 7x - 34 - 10 = 10 - 10
x² - 7x - 44 = 0
x² + 4x - 11x - 44 = 0
x (x + 4) - 11 ( x + 4) = 0
(x - 11)(x + 4) = 0
(x - 11) = 0 / (x + 4) = 0
x = 11 / x = - 4
Hope that helps! (If it doesn't, please tell me what you want me to answer or explain, or how I can improve the answer.) :)
A county has a goal to build 12,000 bus stop shelters in 48 months . If the county builds 215 bus shelters each month , will it reach its goal ? Explain one way to estimate the answer.
Answer:
No, it will not reach its goal.
Step-by-step explanation:
The main reason why it will not meet its goal is because if you do the math, 215 x 48 does not equal 12000, it equals 10320 which is just 1680 shelters low. Therefore, they will not meet their goal.
Answer:
No
Step-by-step explanation:because if you do the math if you do 215 x 48 in doesn't reach to 12000 at all.

¨Five times the sum of two numbers¨
[tex]5(x+y)[/tex]
¨The difference of 5 and a number squared¨
[tex](5-x)^{2}[/tex]
Answer:
First Box is: 5 - 2x
Second Box is: 5(x + y)
Third Box is: (5 - x)²
Step-by-step explanation:
The First one said "Five less than twice a number"
It said Five less than, meaning 5 (subtract)Twice mean 2 and a number means a VARIABLE. Answer: 5 - 2xThe second one said "Five times the sum of two numbers"
Five times means 5 (multiplication)Sum means adding and two numbers means two variables.Answer: 5(x + y)The thrird one said "The difference of 5 and a number, squared"
The difference means subtracting of 5a number means a variablesquared, means an exponent of 2Answer: (5 - x)²All of these answers seems to fit the descriptions.

what is 125% of 12.8
The required value of the given percentage is 16. "125%" represents 125 parts out of 100, which is equivalent to 1.25 times the original value.
To find 125% of 12.8, we can multiply 12.8 by 1.25.
First, we convert the percentage to decimal form by dividing it by 100. So, 125% becomes 1.25.
Next, we multiply 12.8 by 1.25:
12.8 × 1.25 = 16.
Therefore, 125% of 12.8 is 16.
Multiplying 12.8 by 1.25 increases it by 25% or adds one-quarter of the original value. Thus, the result of 16 represents an increase of 25% from 12.8.
Thus, the required value of the given percentage is 16.

Factor using GCF then AC:
9x2 - 39x - 30
Answer:
3(x^2-13x-10)
Step-by-step explanation:
You can only factor out 3, as that is the only thing these have in common.
Solve 3(x – 6) + 3 = –9.
Answer:
d) x = 2
Step-by-step explanation:
3(x - 6) + 3 = -9
open the parenthesis
3x - 18 + 3 = -9
3x - 15 = -9
add 15 to both sides of the equation
3x - 15 + 15 = - 9 + 15
3x = -9 + 15
3x = 6
divide both sides by 3
3x/3 = 6/3
x = 6/3
x = 2
The value of x will be;
⇒ x = 2
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 3 (x - 6) + 3 = - 9
Now,
Since, The expression is,
⇒ 3 (x - 6) + 3 = - 9
Solve for x as;
⇒ 3x - 18 + 3 = - 9
⇒ 3x - 15 = - 9
⇒ 3x = 15 - 9
⇒ 3x = 6
⇒ x = 2
Thus, The value of x = 2

Calculate the slope of the line on the graph using the
formula:
72-V1
m
X2 - X
The slope of the line is
_____m/s.
Given:
The graph of a line which represents position (m) at time (s).
To find:
The slope of the line.
Solution:
Formula for slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
From the given graph it is clear that the line passes through two points (0,0) and (1,4).
Using the above formula, we get
[tex]m=\dfrac{4-0}{1-0}[/tex]
[tex]m=\dfrac{4}{1}[/tex]
[tex]m=4[/tex]
Therefore, the slope of the line is 4 m/s.

Make x the subject of the formula
p+x=t
Answer:
x=t-p
Step-by-step explanation:
just move p to the other side and since it crosses the equals sign so you have to change it from positive to negative
Answer:
x=t-p
Step-by-step explanation:
To make x the subject of the formula, you’d have to take p to the other side. And when (+p) crosses over to the other side, it changes to (-p) because of the equality sign.
Suppose you are driving. You notice that after driving for 4 hours, you are 135 miles from Seattle. You continue driving, and calculate that after driving 8 hours you are 255 miles from Seattle. What is your rate? How far do you drive every 9 hours? How far from Seattle are you after driving for 17 hours?
Answer:
1,423
Step-by-step explanation:
Your average rate is 36.7 miles per hour over nine hours
What is Average speed?Average speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.
In the first 4 hours, you've averaged 33.75 miles per hour, but this is apparently not sustainable, since at 9 hours you've only averaged 36.7 miles/hour.
You continue driving, and calculate that after driving 8 hours you are 255 miles from Seattle. you've averaged 31.8 miles per hour
So the answer is that your average rate is 36.7 miles per hour over nine hours, although you did manage a faster burst of 50 mph for four hours once.
