Evaluate for the following values:
w = 12
x = 1/2
We Substituting the values we have:
[tex]13- 0.75 * (12) + 8 * (\frac{1}{2} ) = 13-9+4\\\\13-5=8[/tex]
Therefore, the result after evaluating the expression is: 8Find the area of the square below. Each unit on the grid represents one unit. Make sure you show your work and/or explain how you solved it.
Answer:
Area of the rectangle A = 17 units²
Step-by-step explanation:
Area of the rectangle A = Area of rectangle ACEG - (Area of the triangle ABH + Area of triangle BCD + Area of triangle DEF + Area of the triangle FGH )
Area of rectangle ACEG = Length × Width
= (5 units) × (5 units)
= 25 square units
Area of the triangle ABH = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(4)(1)[/tex]
= 2 units²
Area of the triangle BCD = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(1)(4)[/tex]
= 2 units²
Similarly, area of the triangle DEF = 2 units²
And area of the triangle FGH = 2 units²
Now area of the rectangle A = 25 - (2 + 2 + 2 + 2)
= 25 - 8
= 17 square units
Therefore, area of the rectangle A = 17 square units
what is standard form of 42/-10

Comment on "standard form"
In the US, a number is in standard form if it is written as a sequence of decimal digits and a decimal point (if there is a fractional part), usually with no leading zeros (left of the decimal point). The sign is prepended to that digit string, as shown above.
In the UK, a number is in standard form if it is written in "scientific notation." The rule for writing a number in standard form is that first you write down a number between 1 and 10, then you write ×10(to the power of an integer). Usually powers of 0, or multipliers of 1, are not written. Then the number here is still -4.2, rather than -4.2×10⁰.

Solve for r.
–16r + 15 + 17 = 7(–3r + 16) − 5r
r =
Answer:
r = 8
Step-by-step explanation:
→Distribute the 7 to (-3r + 16):
-16r + 15 + 17 = 7(-3r + 16) - 5r
-16r + 15 + 17 = -21r + 112 - 5r
→Add like terms:
-16r + 32 = -26r + 112
→Add 26r to both sides:
10r + 32 = 112
→Subtract 32 from both sides:
10r = 80
→Divide both sides by 10:
r = 8
Answer:
Step-by-step explanation:
-16r +15+17= 7(-3r+16)-5r
-16r+32 = -21r +112-5r
-16r +26r=112-32
10r =80
r=80/10
r=8

A rectangle has sides of 4 and 6 units. Which expression could you use to find the volume (in
cubic units) of the three-dimensional object formed by continuously rotating the rectangle about
the shorter side?
Answer:
144π
Step-by-step explanation:
If the rectangle below is continuously rotated about side, the solid figure formed is a cylinder.
A rectangle with sides of 4 and 6 unit continuously rotated about the shorter side gives a cylinder with a radius (r) of 6 units and a height (h) of 4 units. The volume of a cylinder is given by:
Volume = πr²h
Volume = π × 6² × 4 = 144π
The volume of the cylinder formed is 144π

Answer:
The ordered pair generated from the equation is (1, 6).
Step-by-step explanation:
An ordered pair is a pair of numbers, representing two variables, in a specific order. For instance, (x, y) = (1, 2) here x = 1 and y = 2.
The equation provided is:
[tex]y=2x+4[/tex]

A. a numerical equation
B. an algebraic equation
C. a numerical expression
D. an algebraic expression
Answer:
C. a numerical expression.
Step-by-step explanation:
Right away, what you should know is that this is an expression. Equations are expressions, except wiht an equal sign. This is not algabraeic though, since there is no valuable (for example 3x, or 7a). So, through the process of elimination, the answer would be a numerical expression.

a car travels at 54 km/h for first 20seconds , 36km/h for next 30seconds and finally 18km/h for next 10 seconds find the averade velocity
Answer:
39 km/h
Step-by-step explanation:
Velocity is the rate of change of distance in a given direction with time. Mathematically,
Velocity = Displacement/time
Like speed, velocity is measured in Km/h or m/s.
Given that the car travels at 54 km/h for first 20seconds,
since 60 seconds = 1 minute and
60 minutes = 1 h,
20 seconds
= 20/(60 ×60) h
= 1/180 h
In the same vein,
30 seconds
= 30 / (60 ×60) h
= 1/120 h
10 seconds
= 10/(60 ×60) h
= 1/360 h
Hence if the car travels 54 km/h for 10 seconds, the distance covered
= 54 × 1/180
= 3/10 Km
If the car travels 36km/h for next 30seconds, the distance covered
= 36 × 1/120
= 3/10 Km
If the car travels 18km/h for next 10 seconds, the distance covered
= 18 × 1/360
= 1/20 km
Total distance = 3/10 Km + 3/10 Km + 1/20 Km
= 13/20 Km
Total time spent = 20 + 30 + 10
= 60 seconds
= 1/60 h
Average velocity = 13/20 km/ 1/60 h
= 39 Km/h
