Answers
Answer:
50 C = 122 F
Step-by-step explanation:
50°C × 9/5 +32
Answer:
50°C = 122°F.
Step-by-step explanation:
Given : The formula to convert F° to C° is [tex]C = \frac{5}{9}( f - 32)[/tex].
To find : Convert 50°C to °F
Solution : We have given
[tex]C = \frac{5}{9}( f - 32)[/tex].
On multiplying by 9 both sides.
[tex]9 C = 5( f - 32)[/tex].
On dividing both sides by 5
[tex]\frac{9C}{5} =( f - 32)[/tex].
On adding both sides by 32
[tex]\frac{9C}{5}+ 32 = f[/tex].
Then plug C = 50°
[tex]\frac{9 * 50 }{5}+ 32 = f[/tex].
[tex]\frac{450}{5}+ 32 = f[/tex].
[tex] 90+ 32 = f[/tex].
[tex] 122°= f[/tex].
Therefore, 50°C = 122°F.

The density of apple juice is 1.04 grams per cm3. The density of fruit syrup is 1.6 grams per cms The density of sparkling water is 0.99 grams per cm3. 35 cm of apple juice are mixed with 25 cm3 of fruit syrup and 270 cm3 of sparkling water to make a drink with a volume of 330 cm3. Work out the density of the drink. Give your answer correct to 3 decimal places.
Answers
Answer:
Density = 1.042 grams /cm^3
Step-by-step explanation:
Work out the mass of each of three in a unit volume (cm^3)
Givens
Apple Juice = 1.04 grams / cm^3Fruit Syrup = 1.6 grams / cm^3Sparkling water = 0.99 grams / cm^3Mixture
35 cm^3 Apple Juice = 1.04 grams / cm^3 * 35 cm^3 = 36.4 grams
25 cm^3 Fruit = 1.6 grams/cm^3 * 25 cm^3 = 40 grams
270 cm^3 water = 0.99 * 270 267.3 grams
Total Mixture
Volume = 25 + 35 + 270 = 330 cm^3Mass = 36.4 + 40 + 267.3 = 343.7 gramsDensity
Density = mass / volume = 343.7 / 330 = 1.0415
Answer
1.042 grams / cm^3
The density of the resulting drink is; 1.042 grams per cm³.
To find the density of the resulting drink, we need to first determine the mass of each of the constituents.
The masses of the constituents can be found as follows;
Mass = density × volumeFor apple juice;
Mass(a) = 1.04 × 35 = 36.4gramsFor fruit syrup;
Mass(f) = 1.6 × 25 = 40grams.For sparkling water;
Mass(s) = 0.99 × 270 = 267.3gramsTherefore, the total mass of the drink is;
= 36.4 + 40 + 267.3 = 343.7 grams.And, since the total volume of the drink is 330cm³
Density of the drink = 343.7 grams/ 330 cm³Density of the drink = 1.042 grams per cm³.

how many meters are in 5 millimeters are in 2 kilometers?
Answers
Answer:
5 mililmiters = 0,005 meters = 0,000005 kilometers
2 kilometers = 2000 meters
Step-by-step explanation:
km / hectometer / decameter / meter / dcm / centimeter / milimeter
1000 m / 100 m / 10 m < 1 > 0,1 m/ 0,01 m / 0,0001 m
1 meter = 0, 1 decimeters / 0, 01 centimeters /0, 000 1 millimeters
1 meter = 10 decameters / 100 hectometers / 1000 kilometers
so 5 millimeters = 0,005 meters = 0, 000 005 kilometers
so 2 km = 2 000 meters = 2 000 000 millimeters
the reference unit of measure is the meter.

Answers
Answer:
y = 6/5 x-1 slope intercept form
6x-5y = 5 standard form
Step-by-step explanation:
We have the points (0,-1) and (-5,-7)
We can find the slope using
m = (y2-y1)/(x2-x1)
= (-7--1)/(-5-0)
= (-7+1)/(-5-0)
= -6/-5
= 6/5
We also have the y intercept ( when x=0) It is -1
We can use the slope intercept form of the equation y = mx+b
y = 6/5 x-1
Depending on what you mean when you say simplify your answer
We can put it in standard form ax+by = C
Multiply both sides by 5
5y =5* 6/5 x-1*5
5y = 6x-5
Subtract 6x from each side
-6x+5y = 6x-6x-5
-6x+5y = -5
Multiply by -1
6x-5y = 5

Round the fraction to the nearest 1/2.
1/9
A 0
B 1/2
C 1
Answers
Answer:
0
Step-by-step explanation:
while rounding the fraction to half,it is to remember that
anything less than 1/4 can be rounded to zero.
anything equal or 1/4 or greater and less than 3/4 can be rounded to 1/2.
anything greater than 3/4 and less than 1 can be rounded to one.
so,1/9<1/4
the value is 0.
Final answer:
The fraction 1/9, when rounded off to the nearest 1/2, is closest to 0, so it rounds down to 0.
Explanation:
To round the fraction 1/9 to the nearest 1/2, you must decide which multiple of 1/2 (0, 1/2, or 1) it is closest to. Since 1/9 is less than 1/2, the first decision is whether it's closer to 0 or to 1/2. Since 1/9 is much smaller than 1/2, it makes sense to round it down to 0. Therefore, when rounding 1/9 to the nearest 1/2, the answer is 0.
The area of a trapezoid is given by the formula A = 1 2 h(B + b). Solved for b, this formula becomes b =
Answers
Answer:b = (2A - hB)/h
Step-by-step explanation:
See , we know area of a trapezoid is equal to 1/2*(sum of parallel sides)* perpendicular distance between parallel sides.
Here B and b are parallel sides which we know by comparing the equation.
And 'h' here is the perpendicular distance between parallel sides.
We have to write the equation in terms of one of the parallel sides 'b'
Our formula is A = 1/2*h*(B+b)
I.e. 2A = h*(B+b) (Multiplying both sides by 2)
I.e. 2A - hB = hb
I.e. b = (2A - hB)/h

{y=2x-4; x+2y=12}
Answers
Substitute y = 2x - 4 to x + 2y = 12:
x + 2(2x - 4) = 12 use distributive property
x + (2)(2x) + (2)(-4) = 12
x + 4x - 8 = 12 add 8 to both sides
5x = 20 divide both sides by 5
x = 4
Put the value of x to the first equation:
y = 2(4) - 4
y = 8 - 4
y = 4
Answer: x = 4 and y = 4Answer:
x=4, y=4
Step-by-step explanation:
y=2x-4;
x+2y=12
We can use substitution since the first equation is solved for y
Where ever you see y in the second equation, replace it with 2x-4
x + 2(2x-4) = 12
Distribute the 2
x+4x-8 = 12
Combine like terms
5x-8=12
Add 8 to each side
5x-8+8=12+8
5x=20
Divide by 5
5x/5 = 20/5
x =4
We still need to solve for y
y = 2x-4
We know x =4
y = 2(4) -4
y = 8-4
y=4

What is a expression? What is a mathematical equation? What is Equation Modelling?
A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Nate and Laura picked apples. Laura picked 1/2 as many as Nate picked. Together they picked 90 apples.
Let [n] stand for the number Nate picked. Then, the number of apples picked up by Laura will be (1/2)n. Then, we can write -
Equation : (1/2)n + n = 90
1.5n = 90
n = (90/1.5)
n = 60
Apples picked up by Nate : 60
Apples picked up Laura : 60/2 = 30
Therefore, the answers to all the parts are -
Equation : (1/2)n + n = 90
Apples picked up by Nate : 60

The factored equivalent expression for 12z+36 is 12(z + 3) after factoring out the common factor of 12.
Explanation:When asked to write all factored equivalent expressions for 12z+36, we look for common factors. Both terms have a common factor of 12. Factoring out the 12, we get 12(z + 3). There are no other common factors, and the expression cannot be factored further as both terms within the parentheses are prime with respect to each other.
