A heartbeat take 0.8 second. How many is this written as a fraction ?
Answer: 8/10
Step-by-step explanation: Using the place value chart, we can see that 0.8 means eight-tenths which can be written as the fraction 8/10. Since 8/10 is not in lowest terms, we need to divide both the numerator and denominator by the greatest common factor of 8 and 10 which is 2 to get 4/5.
Therefore, 0.8 can be written as the fraction 8/10.

What is equation?
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
According to question, we have to find the value of x in the equation [tex]0.7x -1.4 = -3.5[/tex]
Now,[tex]0.7x -1.4 = -3.5[/tex]
⇒[tex]x=\frac{-2.1}{0.7} \\[/tex]
⇒[tex]x=-3[/tex]
So,-[tex]3[/tex] is the value of x in the equation [tex]0.7x -1.4 = -3.5[/tex]
Hence, Option(B) is correct.

josh saved 1/4 of his pocket money and spent 1/2 of the remainder. What fraction did he spend
Answer: [tex]\dfrac{3}{8}[/tex]
Step-by-step explanation:
Let x denotes the total pocket money Josh has.
As per given , we have
Saved pocket money = [tex]\dfrac{1}{4}x[/tex]
Money Remains = [tex]x-\dfrac{x}{4}=\dfrac{3x}{4}[/tex]
Money he spent = [tex]\dfrac{1}{2}[/tex] of (Money Remains)
= [tex]\dfrac{1}{2}\times\dfrac{3x}{4}[/tex]
[tex]=[/tex][tex]\dfrac{3x}{8}[/tex]
Hence, the fraction of money he spent = [tex]\dfrac{3}{8}[/tex]

20 9\16 + 24 5\8 + 21 5\16 + 23 3\8 DON'T SIMPLIFY
Answer:
88 14/16
Step-by-step explanation:
I call these mixed numbers, a mixed number is written as a b/c and it means
[tex]a+\frac{b}{c}[/tex]
So, we can use the above to re arrange our expression to a more convenient presentation.
we have>
[tex]20+\frac{9}{16} + 24+\frac{5}{8} + 21+\frac{5}{16}+23+\frac{3}{8}\\ \\88+\frac{14}{16} +\frac{8}{8} \\\\89+\frac{14}{16}[/tex]
88 14/16, we tend to no simplify this expression anymore since, the number 14/16 usually means something in real life, like the diameter for a construction pipe
Which graph represents the line
10x + 5y = 20?
Answer:
Option 1.
Step-by-step explanation:
The given equation of the line is 10x + 5y = 20
Now we will convert this equation into y-intercept form
10x + 5y = 20
5y = 20 - 10x
y = [tex]\frac{1}{5}[/tex] (20 _ 10x)
= -2x + 4
y-intercept of the line is 4 which gives us hint that graph (1) or (2) may be the correct option.
Since slope is (-2)
So from graph (1) slope of the line passing through (0,4) and (-2,0) = [tex]\frac{4.0}{0+2}[/tex] = 2
Therefore, graph A is not the answer.
For graph (2) slope of the graphed line passing through (0,4) and (2,0) = [tex]\frac{4-0}{0-2}[/tex] = (-2)
So graph (2) is representing the line y = -2x +4

What is co-ordinate geometry?Coordinate geometry is defined as the study of geometry using the coordinate points. Coordinate geometry is required to provide a link between algebra and geometry through the use of line and curve graphs.
Given that:
Replace x in f(x) with x + 4 to translate 4 units to the left.
Replace x in f(x) with x - 4 to translate 4 units to the right.
Since you want to go left,
f(x) → f(x + 4)
f(x) = (x + 4) - 5
∴f(x) = x - 1
Therefore, the given equation translated 4 units to the left is x - 1.

Solve for h.
−110=13+3(4h−6)
Answer:
the value of h is, -8.75
Step-by-step explanation:
The distributive property says that:
[tex]x \cdot (y+z) = x\cdot y+ x\cdot z[/tex]
Given the equation:
[tex]-110=13+3(4h-6)[/tex]
Apply the distributive property we have;
[tex]-110=13+12h-18[/tex]
Combine like terms;
[tex]-110=12h-5[/tex]
Add 5 to both sides we get;
[tex]-105=12h[/tex]
Divide both sides by 12 we get;
-8.75 = h
or
h = -8.75
Therefore, the value of h is, -8.75

Write an absolute value equation that has the solutions x=-10 and x=-5
An absolute value equation with solutions -10 and -5 is |x + 7.5| = 2.5. This is determined by finding the midpoint between -10 and -5, and then expressing the equation to reflect that distance.
To write an absolute value equation that has the solutions x=-10 and x=-5, you must consider the midpoint between these two solutions. The midpoint or average is found by adding the values together and dividing by 2, which we can write as (x + 10 + x + 5)/2. Simplifying, we get (2x + 15)/2 = x + 7.5 as the midpoint. Now an absolute value equation that holds the given solutions will have its vertex (the point where the absolute value expression equals zero) at this midpoint and the same distance from both -10 and -5, which is 2.5 units. So, the equation looks like |x + 7.5| = 2.5.

Point p is the midpoint of DE. DP =3x + 2 and DE = 10x - 12. What is the length of DP
The length of DP is:
DP=14 units
Step-by-step explanation:It is given that:
Point P is the midpoint of DE.
DP =3x + 2 and DE = 10x - 12.
We know that a midpoint divides the given line segment into two equal parts (i.e. it bisects a line segment)
Hence, we have:
DP+PE=DE
Also, DP=PE
This means that:
2DP=DE
2(3x+2)=10x-12
2×(3x)+2×2=10x-12

x=16/4
x=4
Hence,
DP=3x+2=3×4+2

DP=14
Which are perfect cubes? Check all that apply. 64 x^16 8x^3 27x^4 81x^6 125x^9
The perfect cubes from the given options are 64x^16, 8x^3, 81x^6, and 125x^9 as they can all be expressed as the cube of an integer or a product of an integer and variable raised to an exponent that is a multiple of three.
Explanation:The question is asking us to identify which expressions are perfect cubes. A perfect cube is a number that can be expressed as the cube of an integer. The expression for a perfect cube with variables is x3n, where n is a non-negative integer. We apply this principle to the options given:
64x16 is a perfect cube because 64 is 43 and 16 is 3 times 5, making the whole expression (4x5)3.8x3 is a perfect cube because 8 is 23 and 3 is 3 times 1, making the whole expression (2x)3.27x4 is not a perfect cube because 4 is not a multiple of 3.81x6 is a perfect cube because 81 is 34 and 6 is 3 times 2, making the whole expression (3x2)3.125x9 is a perfect cube because 125 is 53 and 9 is 3 times 3, making the whole expression (5x3)3.Therefore, the perfect cubes from the options given are 64x16, 8x3, 81x6, and 125x9.
