Answer:
The length and width of another rectangular field with same perimeter but a larger area is 80 m by 70 m
Step-by-step explanation:
The perimeter of the existing field is
2(l + b)
= 2(90 + 60) = 2(150) = 300 yards
So we want another field having the same perimeter but a larger area
The area we have here is 90 * 60 = 5,400 square yards
If we had 80 by 70
Perimeter will still be 2(70 + 80) = 150
But the area will be 80 * 70 = 5,600 square yards

write this number in scientific notation 5.738,000
Answer:
Step-by-step explanation:
5,738.00= 5.738*10^3
can someone teach me how to write this in standard form ?
Answer:
2x + 5y = 7
Step-by-step explanation:
Here, 2x = 7 - 5y is given
The Standard form of equation is
Ax + By = C
Here, Ax = 2x; By = -5y; C = 7
Now, we get
2x = 7 - 5y
2x + 5y = 7
Here we get Ax = 2x; By = 5y; C = 7
Thus, The Standard form of equation is
2x + 5y = 7

If you purchase a DVD player that costs $625, and the tax rate is 8%, how much will it cost?
Answer:
675
Step-by-step explanation:
8%=$50
Answer:
$675
Step-by-step explanation:
Since tax is an added 8% you are in sense paying for 100% of the DVD and 8% for tax, or 108% of the DVD player. Now convert percent to decimals by dividing by 100 to get 1.08. Now you can multiply 1.08 x $625 and get $675
A rectangle has a length of (x + 4) centimeters and a width of 2/4 x centimeters. If the
perimeter is 35 centimeters, what is the length of the rectangle?
A: 3cm
B: 9cm
C: 13cm
D: 7cm
Answer:
C: 13cm
Step-by-step explanation:
Given;
length of the rectangle, L = (x + 4) cm
width of the rectangle, W = [tex]\frac{2}{4}x[/tex] cm
perimeter of the rectangle, P = 35 cm
The perimeter of a rectangle is given as;
P = 2(L + W)
Substitute the givens;
[tex]35 = 2[(x+ 4) + \frac{2x}{4} ]\\\\35 = 2[\frac{6x}{4} +4]\\\\35 = 3x+8\\\\3x = 27\\\\x = \frac{27}{3}\\\\x = 9[/tex]
Then, L = (x + 4) cm
L = (9 + 4) cm
L = 13 cm
Therefore, the length of the rectangle is 13 cm

Which expression shows the amount of tax on a t shirt that cost x dollars, if tax is 7%
Answer:
2nd option: 0.07
Step-by-step explanation:
100% in decimal form is 1.00. S0, 7 is really 0.07. Hope this helps. Mark brainliest if it does!
The expression which represents the amount of tax on a t-shirt that cost x dollars, if tax is 7% is 0.07x.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is just like the amount of that value but between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.
Given that,
Cost of t-shirt = x dollars
Tax is 7% which means tax is 7% of the cost of the t-shirt
7% of x ⇒ 7/100 × x = 0.007x
Hence "The expression which represents the amount of tax on a t-shirt that cost x dollars, if tax is 7% is 0.07x".

Answer:
a=15
Step-by-step explanation:
Pythagorean Theorum says that a²+b²=c², so if we square b and c, subtract b² from c², and then square root that answer, it will equal a.
a²+8²=17²
8²=64
17²=225
225-64=225

Step-by-step explanation:
Add 6 to both sides of the inequality.
y ≥ − 8 + 6
Add − 8 and 6 .
y ≥ − 2
The result can be shown in multiple forms.
Inequality Form:
y ≥ − 2

Kristi gets $10 a week from her parents if she washes the dishes after dinner every night. Kristi has saved up $30 over the last few weeks from her allowance. She wants to continue saving her allowance until she has enough money to buy the $7o bike she saw at the store last week. Assuming Kristi receives her allowance every week, write an equation that shows how many more weeks Kristi has to save her allowance to buy the bike, where w is the number of weeks. You can solve the equation to check your answer.
Answer:
10w = 70-40
Step-by-step explanation:
To get to $70, Kristi has to work 10w. She has already earned $30 and needs to earn the remaining in 10w. Thus,
10w = 70-30
10w = 40
w = 4
She needs to work for 4 more weeks to buy the bike.

Answer:
This relation is a function.
Step-by-step explanation:
This relation is a function because a there should be no repeating x-coordinates in the relation for it to be a function and that is exactly what happens in this relation.
Answer:
It is a function.
Step-by-step explanation:
no two different outputs, y, have the same input, x, meaning it passes the vertical line test.

Determine two numbers that have a product of 40 but have a sum of 13.
Answer:
The two numbers are 8 and 5.
Step-by-step explanation:
Let consider x and y to be these two numbers.
So;
(x) * (y) = 40 ---- (1)
x + y = 13 ----- (2)
From (2), let x = 13 - y
Then;
(13 - y) * y = 40
13y - y² = 40
13y - y² - 40 = 0
-y² + 13y - 40 = 0
Multiply through by (-)
y² - 13y + 40 = 0
By factorization;
(y - 8) (y - 5) = 0
y = 8 or y = 5
CHECK:
8 * 5 = 40
8 + 5 = 13
Therefore, the two numbers are 8 and 5.

At 8:00 am, the temperature was -10°F. The temperature dropped 3 degrees per hour for the next 5 hours. What was the temperature at 1:00 pm?
Answer:
-25 °F
Step-by-step explanation:
First, we would be multiply 3 by 5 to find the number we would be subtracting from the original
3 * 5 would give us 15
Then we subtract -10 by 15 and get -25 °F
The temperature at 1:00 PM would be -25 °F
A drawer contains 6 pink gloves and 5 yellow gloves. What is the probability that you select two pink gloves if you reach in the drawer and randomly grab two gloves without replacement?
1/11
1/30
2/11
3/11
1/15
Answer:
[tex]\dfrac{3}{11}[/tex]
Step-by-step explanation:
Given that:
A drawer contains 6 pink and 5 yellow gloves.
Two gloves are randomly drawn without replacement.
To find:
The probability that the two gloves drawn are both pink.
Solution:
First of all, let us have a look at the formula for Probability of an event E:
Formula for probability of an event E can be observed as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
Here, number of favorable cases are to draw 2 pink gloves out of 6, which is equal to:
[tex]_6C_2 = \dfrac{6\times 5}{2} = 15[/tex]
Here, Total number of cases are to draw 2 gloves out of 11, which is equal to:
[tex]_{11}C_2 = \dfrac{11\times 10}{2} = 55[/tex]
Now, the required probability is:
[tex]P(2\ pink\ gloves) = \dfrac{15}{55}\\\Rightarrow P(2\ pink\ gloves) = \dfrac{3}{11}[/tex]
Therefore, the answer is:
[tex]\dfrac{3}{11}[/tex]

A packet of green plantains has 5 plantains. Felix packs 3/5 of a package every 25
seconds. After packing plantains for 1 2/3 hours, how many packages has he prepared?
Answer:
166 Packages
Step-by-step explanation:
1 2/3 hours equals 1 hour and 40 minutes.
100/ (3/5)
166 2/3, we remove the 2/3 since its asking for a whole number
1/2 (2y-6) = 24
1/4 (4-y) = 10 + 24
2 (2y-3) = 4y-6
1/3 (6y-9) = 24 - 3

-3 (3c + 5) = 2 (10 - c)
Answer:-5
Step-by-step explanation:
You need to distribute on both sides so u get
9c-15=20-2c
Move variable to left side and change the sign
-9c+2c-15=20
Move constant to right side and change the sign
-9c+2c=20+15
Connect like terms
-7c=35

Solve 4(x-1) = 2(6-2x)
Answer:
x=2
Step-by-step explanation:
4(x-1) = 2(6-2x)
x=2
Answer:
x=2
Step-by-step explanation:
4(x-1)=2(6-2x)
4x-4=12-4x
Add 4 to both sides
4x=16-4x
Add 4x to both sides
8x=16
Divide by 8 on both sides
x=2
