I think the answer is 63 degrees fell free to mark me brainliest i hope u do have a great day!
Answer:Option C:
64 \ cm^2 is the area of the composite figure
It is given that the composite figure is divided into two congruent trapezoids.
The measurements of both the trapezoids are
b_1=10 \ cm
b_2=6 \ cm and
h=4 \ cm
Area of the trapezoid = \frac{1}{2} (b_1+b_2)h
Substituting the values, we get,
A=\frac{1}{2} (10+6)4
A=\frac{1}{2} (16)4
A=32 \ cm^2
Thus, the area of one trapezoid is $32 \ {cm}^{2}$
The area of the composite figure can be determined by adding the area of the two trapezoids.
Thus, we have,
Area of the composite figure = Area of the trapezoid + Area of the trapezoid.
Area of the composite figure = $32 \ {cm}^{2}+32 \ {cm}^{2}$ = 64 \ cm^2
Thus, the area of the composite figure is 64 \ cm^2
Step-by-step explanation:
Answer:
$40 per week
Step-by-step explanation:
Step one:
Given data
the initial amount is = $100
the total amount= $500
let the number of weeks be x
Step two:
The expression for the scenario is
From the expression above, the rate of the change is $40 per week.
this means that in every week the account will be increased by $40
Answer:
s=7
p=3s
Step-by-step explanation:
The perimeter is the side length times 3
So the equation would be p=3s
Plug in 21 for p
21=3s
That means s=7
Answer:
(a) 51,100 kilometers.
(b) meters
Step-by-step explanation:
(a) When converting from scientific notation to standard notation, split the equation.
When solving , begin by calculating .
= 10,000
Multiply this by '5.11', resulting in:
5.11 × 10000 = 51,100 kilometers.
(b) When converting from standard form to scientific notation, count the number of zeros until the first non-zero digit. Therefore:
In 0.00000768, the '7' is placed 6 digits from the decimal. Recall that for decimals, the exponent is negative. Therefore in scientific notation, this equals:
