Answer:

Step-by-step explanation:

The three angles of a triangle always have to equal 180 in the end, so if you use the method which is the 4 in this instance, it is an obtuse angle that is equal to the top and left angle. You can add 1 and 2 to get 4, and do 4-3 to get 1+2, So, 4=1+2.

The sides of a triangle are as follows:
AB = 10 in
BC = 14 in
AC = 8 in
Order the angles of the triangle from smallest to biggest.

Can any kind soul help me please

Answers

Answer:

(i) we will be finding the acceleration here, in the first 20 seconds the velocity was 10

a = velocity/time

a = 10/20

a = 0.5 ms -2

(ii) difference in distance of the bus and bicycle will be given by formula of velocity

velocity of bicycle

10 * 80 = distance

800 metres

velocity of bus

for first 20 seconds( distance= velocity* time)

200 metres

from 20 seconds to 60 seconds, it will be for 40 seconds

then distance will be,

400 metres

final 20 seconds

200 metres

adding the distances of bus it will be 800 metres.

the difference in distance will be 0 metres.

this is wat i think

What is the coefficient for 9x=18?

Answers

Answer:

If ur looking for the answer for x then its 2

Step-by-step explanation:

9 times 2 = 18

there u go

9x=18
9x/9=18/9
X=2

If you have 9x it is best to assume it is 9 times x which means to get it by itself, you must divide by, in this case, 9 on both sides. This gets x by itself and the answer on the other side.

x=2

Find the linear equation for the following functions

Answers

Answer:

1st one) y = x - .8

Step-by-step explanation:

1st one) you start by finding the slope of the line which can be found with y1 - y2/x1 - x2 (in this case: 3.6-2.4/2-1 which = 1/1, or the slope is one). now that we know the slope we need to find the x intercept or the point that the line intercepts the x axis, or when y = 0. We know that that for every one we subtract from x, we subtract one from y (hence the slope 1/1). so when we subtract 1.2 from the y we subtract 1.2 from the x. so the x intercept is -.8. If we put this in y = mx+b we get y = x - .8

John caught 24 trout in bass while on a fishing trip. The total weight of his catch was 137 pounds. The average weight of a trout was 2.5 pounds, and the average weight of a bass was 8 pounds. How many trout and how many bears did he catch?

Answers

Answer:

trouts = 10 and bears = 14

Step-by-step explanation:

Let number of trouts and bears be x and y respectively.

This means that since he caught 24 trout and bass, we have;

x + y = 24 - - - (eq 1)

Now, average weight of trout is 2.5 pounds and average weight of bass is 8 pounds.

Thus;

2.5x + 8y = 137 - - - (eq 2)

From eq(1), let's make x the subject.

Thus;

x = 24 - y

Put 24 - y for x in eq(2)

2.5(24 - y) + 8y = 137

60 - 2.5y + 8y = 137

5.5y + 60 = 137

5.5y = 137 - 60

y = 77/5.5

y = 14

x = 24 - 14

x = 10

Thus, trouts = 10 and bears = 14

What is the rate of return for an investor who pays $1,054.47 for a 3-year bond with an annual coupon payment of 6.5% and sells the bond 1 year later for $1,037.19?What is the rate of return for an investor who pays $1,054.47 for a 3-year bond with an annual coupon payment of 6.5% and sells the bond 1 year later for $1,037.19?

Answers

Answer:

4.53%

Step-by-step explanation:

We are told that:

From the question, we have a 6.5 % coupon

Hence = 6.5 × $10

= $65

Price of the bond one year later = $1,037.19

$1,054.47 - $1,037.19

= $17.28

Rate of Return

= ($65.00 - $17.28)/$1,054.47

47.72 ÷ 1054.47 = 0.045254962

0.045254962 × 100 =

4.5254962 %

Approximately = 4.53%

Solving two step equations on both sides -8 + 2/3x + 4 = 2x - 5 - x

2. Tina uSUally brings her children every Sunday afternoon at the children's park in their barangay. The park is 350m Iong and 200m wide complete with slides and
swings for children to play. If is surounded by a pathway of unifom width for children who loves biking and jogging. Suppose the total area of the park and the pathway is 74,464 m2.

a. How wide is the pathway of the park?
b. If you were Tina, woulad you like your children fo go biking and jogging in that park?

Answers

Answer: kindly check explanation

Step-by-step explanation:

Given the following :

Total area of parknand path way = 74,464 m2.

Dimension of park = 350m by 200m

Using the area of rectangle formula:

Area = Length * width

Area of park = 350m * 200m

Area of park = 70,000

Area of path = (74,464 - 70,000) = 4,464m2

Since path has uniform width, then width of the the path is sqrt(4464) = 66.8m

2.) the path of the park seems a bit narrow, hence, I wouldn't love children to bike and jog in such a narrow path
