Answer:
Step-by-step explanation:
20% of 1.75 would be 0.35, do the math, you get 1.40, so the price this week is 1.40$
Part 2 if were using the hint, the percent (20%) in decimal, 20, so it would be 1.75 x 20, which is 35, UNLESS were talking about the new cost, 1.40, so it would be 1.40 x 20 which is 28
Alex grew 1 foot over the past year. He is now 6 feet tall. Write and use a proportion to find the percent increase in Alex's height.
Answer:
Step-by-step explanation:
Last year Alex was 6-1 = 5 feet tall.
1/5 = 0.20 = 20%
The increase in height is 20%

35.06-2.098=32.962
40.00-32.962=7.038
Answer:
7.038
u can find the difference of 35.06 and 2.098 first.
afterwards, u can subtract the difference from 40.00 to get the answer of 7.038
hope it helps:)))
what is the rule for solving any equation?
A. just look at it and it will be solved
B. always add the numbers
C. Do the inverse or opposite operations
D. the is no rule for solving equations
Answer:
C) Do the inverse or opposite operations
Step-by-step explanation:
Take for example the equation 4=2x. Because 2 is being multiplied by x, the only way for x to get by itself is to do the opposite operation; dividing both sides by 2 to get 2=x.

Each time Sally waters her tomato plants she uses 5 liters of water. If Sally waters her tomato plants 3 times a week, then how much water, in liters, does Sally use in a week? liters
Given:
Each time Sally waters her tomato plants she uses 5 liters of water.
Sally waters her tomato plants 3 times a week.
To find:
How much water, in liters, does Sally use in a week?
Solution:
We have,
Water used in each time = 5 liters
Number of times Sally waters her tomato plants = 3 times
Now,
Water used in 1 time = 5 liters
Water used in 3 time = 3×5 liters
= 15 liters
Therefore, the Sally use 15 liters of water in a week.
A large field measures 70 feet by 525 feet. If you divide it up into equal square garden plots, what size would the largest possible plot be with sides of whole number length?
9514 1404 393
Answer:
35 feet square
Step-by-step explanation:
The greatest common factor of 70 and 525 is 35. The largest square plot can be 35 feet on a side.
70 = 2·35
525 = 15·35

I like to find the GCD (greatest common divisor) using Euclid's algorithm. We find the remainder when dividing the larger by the smaller. When that remainder is not zero, we replace the larger number with the remainder, and repeat. When the remainder is zero, the divisor is the GCD.
525/70 = 7 r 35
70/35 = 2 r 0 . . . . . 35 is the GCD

boys=1-7/26(girls)
What is the answer hurry!!!
Answer:
D. 9 + 4√5
Step-by-step explanation:
What we're essentially doing here is squaring 2 + √5. (2 + √5 and 2 + 1√5 are essentially the same)
(2 + √5)(2 + √5) (I didn't put the one on the conjugate for a reason; look above)
Step 1: Apply the distributive property by multiplying each term of 2 + √5 by 2 + √5
4 + 2√5 + 2√5 + (√5)²
Step 2: Combine 2√5 and 2√5 to get 4√5.
4 + 4√5 + (√5)²
Step 3: The square of √5 is 5.
4 + 4√5 + 5
Step 4: Add 4 and 5 to get 9.
9 + 4√5 is the final answer to this question.
Which equation represents the line that has a slope of -2 and passes through the point (6,5)?
A. y= -2.6 - 17
B. Y = -23 - 16
c. y = -2x + 16
D. y = -2.c + 17
Pls don’t write random thing I really need helllppp
Answer:
y = - 2x + 17
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 2, then
y = - 2x + c ← is the partial equation
To find c substitute (6, 5) into the partial equation
5 = - 12 + c ⇒ c = 5 + 12 = 17
y = - 2x + 17 ← equation of line
A=1/2B*3B make b the subject of the formula
2A
or b = √ --------------
3Answer:
Step-by-step explanation:
A = (1/2)B·3B becomes (3/2)·b^2. Solve this for b:
Taking the square root of both sides, we get:
√A = √(3/2)·b, so that

Answer:
z is 95 degrees.
Step-by-step explanation:
Linear angle pairs make 180 degrees. Since ∠ABC is a straight line, it is 180 degrees. And since ∠ABD and ∠DBC are on that line, they are a linear angle pair. You just need to find out what number + 85 degrees would = 180 degrees, which in this case, is 95.

Mrs. Hector wanted to bring giant souvenir snow globes, which weigh 1.5 kg each, back to the USA as presents for her students. Mrs. Hector's suitcase weighs 2.4 kg, but she wanted to fill it with as many snow globes as possible. Write and solve an inequality to determine the maximum number of snow globes that Mrs. Hector could have brought back in her suitcase.
Answer:
the maximum number of snow balls can bought back = 1.6
Step-by-step explanation:
Let
Mrs. Hector brings total number of giant snow globes = x
As given,
weight of 1 snow globe = 1.5 kg
So,
Weight of x snow globe = 1.5x
As given,
She have to take them in a suitcase of weight 2.4 kg
∴
For number of snow globes we have the equation,
1.5x = 2.4
⇒x = [tex]\frac{2.4}{1.5}[/tex] = 1.6
So, the maximum number of snow balls can bought back = 1.6

Which is an example of having infinitely many solutions? 1 Point 2x+8 = 2(x+8) 3x + 2(x - 2) + 6 = 5x + 2 x+7=7 X=0
Given:
The different equations in the options.
To find:
The equation which have infinitely many solutions.
Solution:
In option A,
[tex]2x+8=2(x+8)[/tex]
[tex]2x+8=2x+16[/tex]
[tex]8=16[/tex]
This statement is false for any real value of x. So, the given equation has no solution.
In option B,
[tex]3x+2(x-2)+6=5x+2[/tex]
[tex]3x+2x-4+6=5x+2[/tex]
[tex]5x+2=5x+2[/tex]
[tex]2=2[/tex]
This statement is true for all real value of x. So, the given equation has infinitely many solutions.
In option C,
[tex]x+7=7[/tex]
[tex]x=7-7[/tex]
[tex]x=0[/tex]
This equation has only one solution, i.e., x=0.
In option D,
[tex]x=0[/tex]
This equation has only one solution, i.e., x=0.
Only equation [tex]3x+2(x-2)+6=5x+2[/tex] has infinitely many solutions. Therefore, the correct option is B.
