A weather forecaster says the temperature will be about -5 degrees celcius "give or take" 10 degrees celcius. what is the greatest and least possible temperature?
Answer:
5 is the greatest and -15 is the least.
Step-by-step explanation:
The expression "give or take" means to add or to subtract on both sides. Since the estimated forecast is -5 degrees celcius. We can add 10 and subtract 10 to find the least and greatest possible temperature. -5-10=-15. -15 degrees celcius is the least possible temperature. -5+10=5. 5 degrees celcius is the greatest possible temperature.
Hope this helps!
what is the solution to the equation below?
-3 + sqrt 2x - 1 =8
Answer:
[tex]x=61[/tex]
Step-by-step explanation:
[tex]-3+\sqrt{2x-1} =8[/tex]
[tex]\sqrt{2x-1} -3=8[/tex]
Add 3 to both sides of the equation:
[tex]\sqrt{2x-1}-3+3=8+3[/tex]
[tex]\sqrt{2x-1}=11[/tex]
Solve the square root:
[tex]\sqrt{2x-1}=11[/tex]
[tex]2x-1=11^{2}[/tex]
[tex]2x-1=121[/tex]
[tex]2x-1+1=121+1[/tex] {add 1 to both sides}
[tex]2x=122[/tex]
[tex]x=122/2[/tex]
[tex]x=61[/tex]

What is the value of 5 1/3 - 4 12
Help
Answer:
The answer is 5/6.
Step-by-step explanation:
If both the numbers are mixed then,
(5 1/3) - (4 1/2)
= {(3*5)+1}/3 - {(2*4)+1}/2
= (16/3) - (9/2)
= (32-27)/6
= 5/6
Hope this helps.
LENGHT OF THE RECTANGLE IS 7 LESS THAN THE TWICE OF THE BREADTH THEN FIND ITS DIMENSIONS IF THE PERIMETER IS 40 CM
Step-by-step explanation:
Length of rectangle = 7 less than the twice the breadthPerimeter = 40 cmLet us say the breadth as b and length as l.
→ Length = 7 less than the twice the breadth
→ l = 2b - 7 ...(1)
Now, according to the question,
→ Perimeter of rectangle = 2(l + b)
→ 40 = 2(2b - 7 + b)
→ 40 = 2(3b - 7)
→ 40 = 6b - 14
→ 40 + 14 = 6b
→ 54 = 6b
→ 54 ÷ 6 = b
→ 9 m = Breadth
Now, finding length.
→ l = 2b - 7
→ l = 2(9) - 7 m
→ l = 18 - 7 m
→ Length = 11 m

Step-by-step explanation:
Complete the solution of the equation. Find the
value of y when x equals 0.
6x - 2y = 14
Answer:
y = - 7
Step-by-step explanation:
6x - 2y = 14
x = 0
6(0) - 2y = 14
- 2y = 14
- 2y ÷ - 2 = 14 ÷ - 2
y = - 7

Alicia wants to bake a cake with ⁹/10 grams of flour.However,she only has ⅓ grams of flour she needs.How much does she have?
Answer:
We know that:
She needs 9/10 grams of flour for the cake (this quantity does not make a lot of sense, maybe is written incorrectly, but is the only info we have, so let's solve the problem with this)
She only has 1/3 of the amount she needs.
How much flour does she have?
Well, she needs 9/10 grams, and she has one-third of that.
Then she has (1/3) times (9/10) grams, this is:
F = (1/3)*(9/10) grams
F = (1*9)/(3*10) grams
F = 9/30 grams
That is the amount of flour that she has.

Find the missing angle
Answer option
30 degrees
130 degrees
Given:
The measure of one angle in the figure is 50 degrees.
To find:
The missing angle in the figure.
Solution:
Let x be the measure of the missing angle. Then
[tex]x+50^\circ=180^\circ[/tex] [Supplementary angles]
[tex]x=180^\circ-50^\circ[/tex]
[tex]x=130^\circ[/tex]
Therefore, the measure of the missing angle in the figure is 130 degrees. Hence, the correct option is B.
Calculate the simple interest on a loan of $9000 at an interest rate of 8% for 6 years? PLEASE HELP MEEE
Answer:
Step-by-step explanation:
Rate = 8% = 8 / 100 = 0.08
Time (t) = 6 years
principal (P ) = 9000
i = P *r * t
i = 9000 * 0.08 + 6
i = 9000 * 0.48
i = 4320

Find the length of “b”, to the
nearest tenth, using the
Pythagorean Theorem.
Answer: b= 11.2
10^2 + b^2 = 15^2
100 + b^2 = 225
b^2 = 125
b= [tex]\sqrt{125}[/tex]
b= 11.2
Step-by-step explanation:
Answer:
b = square root of 125
Put into calculator and put to 1dp
Step-by-step explanation:
Pythagorean theorem is
a^2 + b^2 = c^2
The a and b are the two short sides and c is always the hypotenuse
We just put the numbers in
10^2 + b^2 = 15^2
Now we can rearrange so that b^2 is by its self on the left side
b^2 = 15^2 - 10^2
Now just solve by putting into calculator
b^2 = 125
And finally square root to get b^2 down to b
b = square root of 125
Put into calculator and put to 1dp

Lia and Sergio are both saving to buy a
kayak that costs $800. The table shows
Lia'ssavings perweek. Sergio saves
$24 per week. Who will be able to buy
thekayak first? How long willit take?
Answer:
Sergio will buy first
It will take 34 weeks for Sergio
and 45 weeks for Lia
Step-by-step explanation:
Given Info: Per week Sergio Saves $24
How:
divide $72 by 4 weeks to find how much Lia is earning per 1 week.
72/4= 18
So Lia is saving 18$ per week while Sergio saves $24 per week
24>18
Sergio will save more per week so he will get it first.
It will take 34 weeks for Sergio
and 45 weeks for Lia

PLEASE HELP!!!! i need this done tonight and i dont know how to do it
Answer:
x=-2/3
Step-by-step explanation:
So let's start off with adding 4x on both sides, we add them to cancel out the -4x on the right hand side.
4x+-9x=-5x
Now, as for the fractions all we really gotta do here is add and subtract them. Let's subtract 5/6 on both sides. once we do that we get:
2/3+7/2-5/6=-5x
A quick trick for adding and subtract fractions is to cross multiply.
2/3+7/2
Multiply 3 times 7 and 2 times 2, then we'll multiply 3 times 2 to get a denominator.
3*2=6 (our denominator)
3*7=21
21/6
2*2=4/6
21/6+4/6=
25/6
Awesome! Now we have two like denominators so we don't have to do any additional cross multiplying. So, we can subtract 25/6-5/6=20/6.
Now, all we're left with is:
20/6=-5x
We can multiply 6 on both sides to isolate the 20.
20=-30x
Divide -30 on both sides!
x=-2/3

Jamal works at a sporting goods store on the weekends. Suppose last weekend he worked 12.5 hours and earned $110. How much money does Jamal earn per hour? Step I: Write an equation you can use to solve the problem. Be sure to define the variable you use. NOTE: If you are paid hourly, you must multiply your hourly rate by the number of hours worked in a week to find the amount of money made. (4
Answer:
$8
Step-by-step explanation:
12.5 hours earned him $110
then an hour will earn him less
12.5=$110
1=x then you cross multiply
12.5x=110
12.5x/12.5=110/12.5
x=8
therefore an hour will earn him $8
