Answer: 50%
Step-by-step explanation:
Add 25% to 25% : do this because 1/4+1/4=2/4, which is a half. If you add 25% to 25%, you get 50%, and 50% is also 1/2.
Answer:
Step-by-step explanation:
If 1/4 is 25% of 1, then 2/4 in its simplest form is 1/2 or 50%.
Parallel lines p, q and r are cut by transversal t. Which of these describes how to find the value of x
1. Lines p and t are parallel, so the alternate exterior are congruent; x = 130
2. Lines q and r are parallel, so the interior angles are supplementary; x = 130
3. Lines p and r are parallel, so they alternate exterior angles are supplementary; x = 50
4. Lines q and r are parallel, so the corresponding angles are congruent; x = 50
Answer:
Lines p and t are parallel, so the alternate exterior are congruent; x = 130
Step-by-step explanation:
hope you like it it :) god bless you all
we love cheating in iready :3
The correct answer is 2. Lines q and r are parallel, so the interior angles are supplementary; x = 130
What is Transversal?A line that intersects more than two lines is known as transversal.A Transversal cuts the two parallel lines and the angles formed in the transversal are known as transversal angles.How many types of Transversal angles are there?
The types of transversal angles are as follows
Corresponding anglesAlternate Interior AnglesAlternate Exterior AnglesCo-interior AnglesWhy other options are incorrect?
Option 1. is incorrect because Lines p and t are not parallel
Option 3 is incorrect because alternate exterior angles is x= 130°
Option 4 is incorrect because x is not corresponding angle to 50°
Hence , Option 2 is correct and rest options are incorrect.

You are playing basketball with your friends. The height (in feet) of the ball above the ground t seconds after a shot is released from your hand is modeled by the function f(t)= -16t^2 + 32t + 5.2. What is the value of t when the ball is released from your hand ?
Answer:
2.15 seconds
Step-by-step explanation:
Given the equation of the height (in feet) of the ball above the ground t seconds after a shot is released from your hand modeled by the function
f(t)= -16t² + 32t + 5.2 where t is in seconds.
Note that the value of the height at the point the ball is released from the hand is 0 feet.
To get value of t when the ball is released from your hand, we will substitute f(t) = 0 into the modeled equation as shown;
f(t)= -16t² + 32t + 5.2
-16t² + 32t + 5.2 = 0
Multiply through by 10
-160t² + 320t + 52 = 0
Dividing through by -4
40t² - 80t - 13 = 0
t = 80±√80²-4(40)(-13)/2(40)
t = 80±√6400+2080/80
t = 80±√8480/80
t = 80±92.09/80
t = 80+92.09/80
t = 172.09/80
t = 2.15 secs
Hence, the value of t when the ball is released from your hand is approximately 2.15seconds.

A construction crew has just finished building a road. The crew worked for 10 days. If they built 314 kilometers of road each day, what is the total length of road they built?
Answer:
3140
Step-by-step explanation:
If they made 314 kilometers per day and they worked for 10 days, multiply:
[tex]314*10=3140[/tex]
The total length of the road is 3,140 kilometers.
Answer:
1st or each day=314km
Let x in km be the total km for 10 days
10=x
>314×10=x
X=3140km
Therefore, for 10days, the road constructed was 3140km

Jack had lunch with two friends. Their bill for lunch was $29.46.
They want to add a tip of $5.25 and divide the total equally. How
much should each person pay?
.pdf
O $4.57
O $9.82
O $11.57
O 17.36
Answer:
$11.57
Step-by-step explanation:
First, find the total amount they need to pay.
Add the bill for lunch and the tip amount.
bill + tip
The bill was $29.46 and the tip was $5.25
$29.46 + $5.25
$34.71
The total amount with tip is $34.71
Next, find the amount each person should pay.
They want to divide the amount equally. There are 3 total people ( Jack + 2 friends = 3 people). Divide the total ($34.71) by 3.
$34.71 /3
$11.57
Each person should pay $11.57

f(x) = 7x - 4
g(x) = -3x + 2
To find (f+g)(x) add g(x) to f(x)
That's
[tex](f+g)(x) = 7x - 4 + (- 3x + 2) \\ = 7x - 4 - 3x + 2 \\ = 7x - 3x - 4 + 2[/tex]We have the final answer as
[tex](f+g)(x) = 4x - 2[/tex]Hope this helps you
Answer:
[tex]\Large \boxed{(f + g)(x) = 4x - 2}[/tex]
Step-by-step explanation:
We have two functions.
f(x) = 7x - 4
g(x) = -3x + 2
To find (f+g)(x), we have to find the sum of f(x) and g(x).
(f+g)(x) = f(x) + g(x)
(f + g)(x) = 7x - 4 + -3x + 2
Combining like terms.
(f+g)(x) = 7x - 3x - 4 + 2
(f + g)(x) = 4x - 2

After an exercise, Ali and Ben measured their heart rates. The ratio of their heart rates was 15:17 Bens heart beats 18 times per minute more than Ali. Calculate Ali heart rate
Answer:
Ali's heart rate is 135 times per minute.
Step-by-step explanation:
Let Ali's heart rate be denoted by x times per minute.
It is provided that Ben's heart beats 18 times per minute more than Ali.
The ratio of their heart rates was 15:17.
That is:
[tex]\frac{15}{17}=\frac{x}{x+18}[/tex]
Solve for x as follows:
[tex]\frac{15}{17}=\frac{x}{x+18}[/tex]
[tex]15(x+18)=17x\\15x+270=17x\\2x=270\\x=135[/tex]
Thus, Ali's heart rate is 135 times per minute.
write an equation in slope intercept form of the line that passes through (0,2) (8,8)
Step-by-step explanation:
Hey, there!!
You can get your answer simply, just remember the two point formula,
Given, the points are (0,2),(8,8).
We have, Formula for two points is,
[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1) [/tex]
Put all values here,
[tex](y - 2) = \frac{8 - 2}{8 - 0} (x - 0)[/tex]
[tex](y - 2) = \frac{6}{8} (x -0)[/tex]
[tex](y - 2) = \frac{3}{4} (x - 0)[/tex]
multiply (y-4) by 4 and (x-0) by 3.
[tex](4y - 8) = 3x[/tex]
Bringing 4y and -8 on same side of 3x.
[tex]0 = 3x - 4y + 8[/tex]
[tex]or \: 3x - 4y + 8 = 0[/tex]
Therefore, 3x-4y+8=0..... is the required equation.

Allen is showing his work in simplifying-8.3 + 9.2 - 4.4 + 3.7. Identify and explain any errors in his work or in his reasoning. Write feed back to Allen explaining the mistakes he made and how to correct his work
Answer:
Step-by-step explanation:
The question lacks Allen's workings. Find it below.
Step Work Reasoning
−8.3 + 9.2 − 4.4 + 3.7 Original problem
1 −8.3 + 9.2 + 4.4 + 3.7 Additive inverse
2 −8.3 + 4.4 + 9.2 + 3.7 Commutative property
3 −8.3 + (4.4 + 9.2 + 3.7) Associative property
4 −8.3 + 17.3 Simplify
5 9 Simplify
Given the equation −8.3 + 9.2 − 4.4 + 3.7, to solve this we are going to be using different properties.
Given three values A, B and C, the following are true:
A-B = A+(-B) Additive inverse
(A+B)+C = A+(B+C) Commutative property
Applying this laws to correct Allen's calculation
Original problem
−8.3 + 9.2 − 4.4 + 3.7
Applying the additive inverse property
−8.3 + 9.2 +(− 4.4) + 3.7 {since product of plus and minus sign still gives a minus sign)
Rearranging the equation based on signs according to the associative property we will have:
−8.3 +(-4.4) + 9.2 + 3.7
Using the commutative property to separate the positive variables from negative variables will give:
{−8.3 +(-4.4)} + {9.2 + 3.7}
Since {−8.3 +(-4.4)} + {9.2 + 3.7} = {9.2 + 3.7} + {−8.3 +(-4.4)}
Simplify the expressions in parenthesis:
= {−8.3 +(-4.4)} + {9.2 + 3.7}
= (-8.3-4.4)+(9.2+3.7)
= (-12.7)+(12.9)
= 0.2
From the above calculation, it can be seen that Allen made an error while using the additive inverse property in his first step. He should not have removed the minus sign. The negative sign was removed from step 1 which makes the remaining steps of his calculation to be wrong. Instead of replacing -4.4 directly with +4.4 he should have used the additive inverse property by replacing -4.4 with +(-4.4).

but like can you tell us where he did it wrong

Answer:
x = 15 and y = 30
Step-by-step explanation:
We see that 4x + 15 + 5x + 30 = 180.
We can solve for x:
9x + 45 = 180
9x = 135
x = 15.
We also see that 5x + 30 is equal to 3y + 15, so we can solve for y:
5x + 30 = 3y + 15
5 (15) + 30 = 3y + 15
3y = 75 + 30 - 15
3y = 90
y = 30.
