A recipe needs a ratio of 2.5 of sugar to flour. If Joe uses 60g of sugar, how much flour should he use?
Answer:
150 g
Step-by-step explanation:
The 2 part of the ratio represents 60 g , thus
60 g ÷ 2 = 30 g ← value of 1 part of the ratio, then
5 parts = 5 × 30 g = 150 g ← amount of flour required
Mia is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points. What would be Mia's test score (out of 50) if she got 3 questions wrong? What would be her score if she got x questions wrong?
Answer:
Mia's test score is 44 if she got 3 questions wrong.
Mia's test score is (50-2x) if she got x questions wrong.
Step-by-step explanation:
It is given that, Mia is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points.
If she got 3 questions wrong, then
Deducted marks [tex]=2\times 3=6[/tex]
Marks obtained by Mia = Total marks - Deducted marks
[tex]=50-6[/tex]
[tex]=44[/tex]
So, Mia's test score is 44 if she got 3 questions wrong.
If she got x questions wrong, then
Deducted marks [tex]=2\times x=2x[/tex]
Marks obtained by Mia = Total marks - Deducted marks
[tex]=50-2x[/tex]
So, Mia's test score is (50-2x) if she got x questions wrong.

Please help solve the equation 1.5x-0.5=x+3.25
Answer:
x = 7.5
Step-by-step explanation:
Step 1: Subtract x from both sides.
1.5x−0.5−x=x+3.25−x
0.5x−0.5=3.25
Step 2: Add 0.5 to both sides.
0.5x−0.5+0.5=3.25+0.5
0.5x=3.75
Step 3: Divide both sides by 0.5
0.5x ÷ 0.5 = 3.75 ÷ 0.5

You have obviously determined the correct entry in the top box of each pair. What you seem to have failed to observe is that the bottom box in each pair needs exactly the same entry as the top box.
_____
You figure this out by looking at the stuff that is outside the box. The numbers and symbols for the second box show how the function indicated outside the first box is evaluated. That is f(x) at the top becomes 4x at the bottom, where x (in this case) is x/4 for both.

The change in kinetic energy (in joules) as a horse accelerates from canter to gallop is found using the expression 1/2 times 350 times (12 2 Minus 6 2
Answer:
[tex]\mathtt{\Delta K.E = 10500 \ J}[/tex]
Step-by-step explanation:
Given that:
the expression for the change in kinetic energy = [tex]\dfrac{1}{2} \times 350 \times ( 122 -62)[/tex]
Recall that
Kinetic energy K.E = [tex]\dfrac{1}{2}mv^2[/tex]
where,
m = mass of the horse
v = velocity of the horse
The change in kinetic energy between two instant times can be expressed by the relation
[tex]\Delta K.E = K.E_2 - K.E_1[/tex]
[tex]\Delta K.E =\dfrac{1}{2}mv^2_2- \dfrac{1}{2}mv^2_1[/tex]
[tex]\Delta K.E =\dfrac{1}{2}m(v^2_2-v^2_1)[/tex]
where;
m = 350
[tex]v_2[/tex] = 122
[tex]v_1[/tex]= 62
[tex]\Delta K.E =\dfrac{1}{2} \times 350 \times (122-62)[/tex]
[tex]\Delta K.E =\dfrac{1}{2} \times 350 \times (60)[/tex]
[tex]\Delta K.E = 350 \times 30[/tex]

The population of Austin, Texas, was about 494,000 at the beginning of a decade. The population increased by 3% each year. Write an exponential growth model that represents the population y (in thousands) t years after the beginning of the decade. Find and interpret the y-value when t = 10.
Answer:
y(t) = 494 (1.03)^t
y(10) = 663,89
Step-by-step explanation:
An increase in population by 3% each year means that at the end of each year, the population is 1.03 times what it was at the start of the year
This increase in population continues for t years
Exponential growth model that represents the population y (in thousands) t years after the beginning of the decade is
y(t) = 494 (1.03)^t
Where,
y = population
t = number of years
Find y when t = 10
y(t) = 494 (1.03)^t
y(10) = 494 (1.03)^10
= 494 ( 1.3439)
= 663.8866
Approximately y(10) = 663.89
This means that after 10 years from when the population was 494,000, it increased to 663,89.
what is the solution to the equation 1/x=x+3/2x^2
Answer:
3.
Step-by-step explanation:
1/x = (x+3)/(2x^2), where x ≠ 0.
Cross-multiply to give 2x^2 = x(x+3).
2x^2 - x^2 - 3x = 0
x^2 - 3x = 0
x(x - 3) = 0
x = 3 or x = 0 (rejected because equation will be undefined)

5.3x10 4 in standard form.
Answer:
5.3× 10⁴= ?
Step-by-step explanation:
10⁴ can also be written as 10×10×10×10= 10000
so, 5.3 × 10000= 53000
Scientific notations are the way through which a very small or a very large number can be written in shorthand. The value of 5.3×10⁴ in standard form is equal to 53,000.
What are Scientific notations?Scientific notations is the way through which a very small or a very large number can be written in shorthand. In scientific notations when a number between 1 and 10s is multiplied by a power of 10.
For example, 6,500,000,000,000 can be written as 6.5e+12.
Given the numerical value 5.3×10⁴ which is needed to be written in the standard form, therefore, we can write,
5.3 × 10⁴
= 5.3 × 10,000
= 53,000
Hence, the value of 5.3×10⁴ in standard form is equal to 53,000.

Find the distance between the points (-16,10) and (2,-14)
Answer: The distance is 30
Step-by-step explanation:
To find the distance between the two points,find the difference between the x and y values, square them and add them to find their square root.
10 - (-14) = 24
-16 - 2= -18
24^2 + 18^2 = d^2 where d is the distance
576 + 324 = d^2
900 =d^2
d = [tex]\sqrt{900}[/tex]
d= 30
Answer:
d=30
Step-by-step explanation:
distance between 2 points: d
d=√(x2-x1)²+(y2-y1)² (-16,10) and (2,-14)
d=√(2-(-16)²+(-14-10)²
d=√18²+(-24)²
d=√324+576
d=√900
