              ∠ABC = 53°

Step-by-step explanation:

Solution In given triangle, 2B=12x+3

12x+3

∠A = 86 , ∠C = 43°

We know that, Sum of all angles of triangle is 180°

86

∴ ∠A+ ∠B + ∠C = 180°

a

86 + 12x+3+ 43 = 180°

4-3

12x = 180° - 130

X = [tex]\frac{50}{12}[/tex] x = [tex]\frac{25}{6}[/tex]

с

∠ABC = 12x + 3 = [tex]\frac{12}{6}[/tex]x25 +3 → 50+3 = 53

Answer:

28 cm, 32cm , 36cm

Step-by-step explanation:

Given:

To Find:

Solution:

Let:

As, we know that,

★ Perimeter of Triangle = Sum of all sides ★

➝ 7x + 8x + 9x = 96cm

➝ 24x = 96cm

➮ x = 96/24

➮ x = 4

So, length of the sides are:

7x = 7 × 4 ➝ 28cm

8x = 8 × 4 ➝ 32cm

9x = 9 × 4 ➝ 36cm

Given :

To Find :

Solution :

Let us assume the sides be 7x cm, 8x cm and 9x cm.

We know,

[tex]\qquad{ \bold{ \pmb{Sum \: of \: all \: sides \: of \: the \: triangle = Perimeter_{(Triangle)}}}}

[/tex]

So, Substituting the values :

[tex]\qquad { \dashrightarrow{ \sf{7x + 8x + 9x = 96}}}[/tex]

[tex]\qquad { \dashrightarrow{ \sf{24x= 96}}}[/tex]

[tex]\qquad { \dashrightarrow{ \sf{ \dfrac{24x}{24} = \dfrac{96}{24} }}}[/tex]

[tex]\qquad { \dashrightarrow{ \bf{ x = 4 }}}[/tex]

Therefore,

The length of the sides of the triangle are :

[tex]\qquad { \dashrightarrow{ \sf{ 7x \: cm= 7 \times 4 \: cm = \bf \: 28 \: cm }}}[/tex]

[tex]\qquad { \dashrightarrow{ \sf{ 8x \: cm= 8 \times 4 \: cm = \bf \: 32 \: cm }}}[/tex]

[tex]\qquad { \dashrightarrow{ \sf{ 9x \: cm= 9 \times 4 \: cm = \bf \: 36 \: cm }}}[/tex]

Answer:

t = 259.3

Step-by-step explanation:

d = rt ( divide both sides by r )

[tex]\frac{d}{r}[/tex] = t ( substitute values for d and r )

[tex]\frac{596.39}{2.3}[/tex] = t , then

t = 259.3

Answer:

3 or 2.999 (probably 3)

Step-by-step explanation:

So the volume of a cylinder =  πr^2 * h

h = height

r = radius

now we know the radius. Leaving us with a simple equation which is:

π*9*h = 9π*h = 84.78 =

π*h = 9.42

h = 9.42 / π = 2.99847912785......

but we can round this to 2.999 or just 3. if you use 2.999 the volume is 84.79 which is as close as I'm gonna try to get. And you might ask why we're rounding to 2.999 and not 2.998? This is because that huge number is the minimum. And 2.998 is smaller than that huge number, meaning it would technically be less than 84.78 cubic ft. But this doesn't really matter because the answer your teacher is probably looking for is 3.

Reference my work if you're are confused, however, it's really messy so sorry about that.

Answer:

[tex]\displaystyle 4\sqrt{5}[/tex]

Step-by-step explanation:

Use the Pythagorean Theorem:

[tex]\displaystyle a^2 + b^2 = c^2 \\ \\ 8^2 + 4^2 = c^2; \sqrt{80} = \sqrt{c^2} \\ \\ 4\sqrt{5}\:[or\:8,94427191...] = b[/tex]

So, you have this:

Answer:

1/15 is simplest, answer 2/30

Step-by-step explanation:

11/30 - 3/10. Find LCD

Since it's 30, leave 11/30 how it is and turn 3/10 into 9/30

Next, 11-9=2

meaning 2/30, which if you divide by 2 both sides, you get 1/15.

Answer:

so its saying ummm write x with < or > or the other ones but with equal on the bottom

i think the answer here would be x < 5

Step-by-step explanation:

because it cannot be equal to 5 since the circle is hollow. also x just goes to the number less than 5

Answer: i think it is -6 but im not sure I never learned this

Step-by-step explanation:

Step-by-step explanation:

Recursive Rule would get by just carefully analysing the pattern and common difference.

a1 = 0 ,

d = a2-a1 ==> d = -3-0 ==> d = -3 ...(common difference)

so here, an would be,

an = a1 + (n-1) d

==> an = 0 + (n-1)(- 3)

==> an = -3(n-1)

==> an = -3n+3

so the final answer is [an = -3n + 3 ]

The amount of money that you will have at the end of the year from your brand-new savings account is $600.69.

The future value is the value of periodic cash flows in the future.  It can be computed using an online finance calculator as follows:

N (# of periods) = 24 (12 X 2)

I/Y (Interest per year) = 0.12% (0.01% X 12)

PV (Present Value) = $0

PMT (Periodic Payment) = $25

Results:

FV = $600.69

Sum of all periodic payments = $600.00 ($25 X 24)

Total Interest = $0.69

Thus, the amount of money that you will have at the end of the year from your brand-new savings account is $600.69.

Answer:

  0.508 cm

Step-by-step explanation:

Your problem statement tells you that you can find the number of centimeters by multiplying 1/5 inch by 2.54 cm/in:

  1/5 × 2.54 = 0.508

1/5 inch is 0.508 centimeters

Answer:  Yes, Daniel has enough money to buy 2 pens.

=========================================================

Explanation:

x = cost of one pencil

y = cost of one pen

4x = cost of 4 pencils

3y = cost of 3 pens

4x+3y = cost of 4 pencils and 3 pens

100 - (4x+3y) = amount Daniel has left = 7 dollars

100-(4x+3y) = 7 is one equation we can form

Another equation we can form is x = y+3 because "each pencil costs $3 more than each pen".

Let's plug that into the first equation and solve for y.

100-(4x+3y) = 7

100-(4(y+3)+3y) = 7

100 - (4y+12+3y) = 7

100 - (7y+12) = 7

100 - 7y - 12 = 7

-7y + 88 = 7

-7y = 7-88

-7y = -81

y = -81/(-7)

y = 11.57 is the cost of one pen

2y = 2*11.57 = 23.14 is the cost of two pens.

Since this is less than $25, this means he has enough to buy two pens. This assumes that we either ignore tax, or the tax is already included in the listed prices.

Step-by-step explanation:

To Find if -17/-40 equal to -0.425...

We First have to turn -17/-40 into a decimal;

-17/-40 = 0.425 { Negative + Negative = Positive }

Thus,

0.425 > -0.425
