Answer:
1) Volume of triangular pyramid = 33 cm³.
2) Volume of triangular prism = 99 cm³
Step-by-step explanation:
1) Volume of a triangular pyramid is given as;
V_py = ⅓Ah
Where A is area of base and h is height
We see from the diagram that;
A = 11 cm²
h = 9 cm
Thus; V_py = ⅓ × 11 × 9 = 33 cm³
2) Volume of triangular prism is given by;
V_pr = ½bhl
Where;
½bh is area of triangular cross section
l is length
We see from the diagram that ½bh = 11 cm² and L = 9 cm
Thus;
V_pr = 11 × 9 = 99 cm³

Sarah borrows $5575 on a 2 year loan at 3% simple interest. What will be the total amount Sarah has to pay back at the end of year 2?
Answers
Answer:
$5909.50
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year,
then, solving our equation
I = 5575 × 0.03 × 2 = 334.5
I = $ 334.50
The simple interest accumulated
on a principal of $ 5,575.00
at a rate of 3% per year
for 2 years is $ 334.50.

Answers
Answer:
2/3x + 29/12
Step-by-step explanation:
P.S Brace yourself cause this is a lot lol :D
The slope-intercept form is
y=mx+b, where m is the slope and b is the y-intercept.
y=mx+b
First, you divide each term by 12 and simplify:
Divide each term in 12y = 8x + 29 by 12:
12y/12 = 8x/12 + 29/12
Cancel the common factor of 12:
You do this by dividing 12y/12 leaving you just with y = 8x/12 + 29/12
Then you cancel the common factor of 8 and 12:
You do this by factoring 4 out of 8x:
y = 4 (2x)/12 + 29/12
Then you cancel even more common factors:
Factor 4 out of 12:
y = 4 (2)/ 4 (3) + 29/12
Then you cancel the common factor in that dividion (which is 4) Leaving you with 2x/3 + 29/12
Finally, you rewrite the expression:
y = 2/3x + 29/12
Write 0.0065 in standard form

If the sum of measures of angle a and b is 280 degrees, what is the measure of angle C?
A. 80 degrees
B. 160 degrees
C. 140 degrees
D. 40 degrees
Answers
Answer:
40 degrees
Step-by-step explanation:
because angle b and angle a are vertical angles they are congruent and if they add up to 280 you just have to divide that by 2 to get the value of one of the angles
280/2=140
because angle c and angle b are supplementary they are going to add up to equal 180
180-140=40 so c=40

40

Joy has a ribbon that measures 16 yards. She cuts 9 pieces of ribbon to decorate gifts. Each piece of ribbon that Joy cuts measures 4 feet.
What is the length, in yards, of the remaining ribbon?
Answers
Answer:
4 yds
Step-by-step explanation:
So... 16 yards is 48 feet (because one yard is 3 feet so I just multiplied by 3)
and she cuts 9 pcs of ribbon each 4 feet
so it's 9 x 4 = 36
48 - 36 = 12
And 12 feet equals 4 yards
So, Joy has 4 yards of remaining ribbon
Answer:
9.3 yards
Step-by-step explanation: the exact answer is 9.3333333

It can be solved as follows :
[tex]\dfrac{a}{ab-b^2}+\dfrac{b}{ab-a^2}=\dfrac{a}{b(a-b)}+\dfrac{b}{a(b-a)}\\\\=\dfrac{a}{b(a-b)}+\dfrac{b}{-a(-b+a)}\\\\=\dfrac{1}{a-b}(\dfrac{a}{b}-\dfrac{b}{a})\\\\=\dfrac{a^2-b^2}{ab(a-b)}\\\\=\dfrac{(a-b)(a+b)}{ab(a-b)}\\\\=\dfrac{(a+b)}{ab}[/tex]
So, the solution of the given expression is equal to [tex]\dfrac{(a+b)}{ab}[/tex].
