solve this question
a=7+3
Answer:
10Step-by-step explanation:
The answer is 10 because 7 + 3 equals 10!
This can be proven by adding 7 + 3 or by subtracting in a certain way.
7 + 3 = ?
7 + 1 = 8
7 + 2 = 9
7 + 3 = 10
You can show more work by subtracting your answer or 10 in this case, which means that you subtract 7 by 10 or 3 by 10, either way is ok.
If you subtract 7 by 10, ( 10 - 7 ) then you get 3
If you subtract 3 by 10, ( 10 - 3 ) then you get 7
If the number you subtracted matches the number that you didn't subtract, then your answer is correct.
Hope this helps! <3

I have a question on Khan Academy and it says super salad dressing is made with 8 mL of oil for every 3 ml of vinegar which of the following mixtures will take the same as super salad dressing
then it says choose 3 answers there's 5 choices a b c and d a is 80 ml of oil with 30 ml of vinegar
B is 3 ml oil with 8 ml of vinegar
C is 56 mL of oil with 21 mL of vinegar
d 40 mL of oil with 25 mL of vinegar
e is 48 mL of oil with 18 mL of vinegar
Answer:
e
Step-by-step explanation:
8ml x 6= 48ml of oil
3ml x 6= 18ml of vineger
is it one to one or onto? why?
Answer:
Step-by-step explanation:
Given quadratic function is,
f(x) = -x² - x + 1
Range of the function has been defined as (-∞, [tex]\frac{5}{4}[/tex] ]
Domain of the function is a set of all real numbers.
From the graph of this function,
At x = -3 and x = 2, value of y = -5
But for one to one functions, every x value should map to a different value of y.
Therefore, function is not one to one.
Since, every value of domain (x-value) maps the range (y-value) in the given range (-∞, [tex]\frac{5}{4}[/tex] ], function will be defined as onto.
Therefore, this function is ONTO, but NOT ONE TO ONE.
Eric rented a truck for one day the base fee was 16.95 for additional charge of .76 cents for each mile driven eric had to pay 152.23 when he returned the truck how many miles did he drive
Answer:
178 miles
Step-by-step explanation:
Let Eric has driven d miles.
As the rate of charge of driving the truck = 76 cents /mile
So, the charge of driving the truck for d miles = 76d cents= $0.76d
The base fee of the truck was $16.95.
Total money paid at the time of returning the truck = $152.23
So, 16.95+0.76d=152.23
0.76d= 152.23-16.95=135.28
d=135.28/0.76
d=178
Hence, he drives 178 miles.

A particle moves along the curve y = 5x^2 – 1 in such a way that the y value is decreasing at the rate of 2 units per second. At what rate is x changing when x = 1?
Decreasing one fifth unit/sec
Increasing one fifth unit/sec
Decreasing one tenth unit/sec
Increasing one tenth unit/sec
Answer:
The correct option is;
Increasing one fifth unit/sec
Step-by-step explanation:
The equation that gives the curve of the particle of the particle is y = 5·x² - 1
The rate of decrease of the y value dy/dt = 2 units per second
We have;
dy/dx = dy/dt × dt/dx
dy/dx = 10·x
dy/dt = 2 units/sec
dt/dx = (dy/dx)/(dy/dt)
dx/dt = dy/dt/(dy/dx) = 2 unit/sec/(10·x)
When x = 1
dx/dt = 2/(10·x) = 2 unit/sec/(10 × 1) = 1/5 unit/sec
dx/dt = 1/5 unit/sec
Therefore, x is increasing one fifth unit/sec.

On 1 September, Leila starts to go swimming every day.
She swims 30 lengths of the swimming pool every day. The swimming pool is 20m long.
Work out the date when Leila has swum a total of 10 km.
Answer:
22 November
Step-by-step explanation:
First we have to find the total length she swims in 1 day
= 2(length of the swimming pool) x no. of lengths she swims in 1 day
=2x30x20
=120m she covers in 1 day
10km = 10,000m
no of days= total distance/ distance she covers in 1 day
=10000/120
=83.3 days

Answer:

Step-by-step explanation:
Jordan is buying plastic plates for a party.The plates usually cost $2.40 per 10 plates,but they are on sale for 30% off usual price.If jordan buys 50 plates,how much will they cost
30% off means they are paying 70% of the original price.
Sale price = 2.40 x 0.70 = $1.68 for 10 plates
50 plates / 10 = 5
They buy 5 packages of plates.
1.68 x 5 = $8.40
Total price = $8.40
Answer:
Step-by-step explanation:
2.40 X 5 =$12
12 X 0.3=$3.6 off
12-3.6=$8.40
Therefore it'll cost $8.40
find the value of variable y using appropriate identity (y-5)2-(y-3)2=12
Answer:
[tex]\\\qquad\quad\displaystyle\sf {:}\longrightarrow (y-5)2-(y-3)2=12 [/tex]
[tex]\\\qquad\quad\displaystyle\sf {:}\longrightarrow 2y-10-2y-6=12[/tex]
[tex]\\\qquad\quad\displaystyle\sf {:}\longrightarrow 2y-2y-10-6=12 [/tex]
[tex]\\\qquad\quad\displaystyle\sf {:}\longrightarrow -16=12 [/tex]
[tex]\\\qquad\quad\displaystyle\sf {:}\longrightarrow y's\:value\:is\:undefined [/tex]
Answer:
[tex] {(y - 5)}^{2} - {(y - 3)}^{2} = 12 \\ = ( {y}^{2} - 10y + 25) - ( {y}^{2} - 6y + 9) = 12 \\ = {y}^{2} - 10y+ 25 - {y}^{2} + 6y - 9 = 12 \\ = - 4y + 16 = 12 \\ = - 4y = 12 - 16 \\ = - 4y = - 4 \\ = y = \frac{ - 4}{ - 4} \\ = \boxed{y = 1}[/tex]
