Answer:

10^-5= 1/10^5

so option c is correct

Answer:

a = 27

b = 38

c = 19

Step-by-step explanation:

a + b + c = 84

b = 2c

a = 8+c

8+c +2c+c = 84

4c + 8 = 84

4c = 76

c = 19

b = 2(19) = 38

a = 8 + 19  = 27

Answer:

(a+b)²-2ab

Step-by-step explanation:

First we need to factorize (a+b)²

(a+b)² = a² + 2ab + b²

(a+b)² = a²+b²+2ab

Subtract 2ab from both sides

(a+b)² - 2ab = a²+b²+2ab - 2ab

(a+b)²-2ab = a²+b²

Swap;

a²+b² = (a+b)²-2ab

Hence the expression of a² + b² is  (a+b)²-2ab

Answer: 0.4 or 4 i think

Given:

In triangle XYZ, P is the centroid of triangle XYZ, YP = 8, QP = 5, YZ = 10.

To find:

The measure of median YS.

Solution:

We know that a centroid divides a median in 2:1.

P is the centroid and YS is the median. So,

[tex]YP:PS=2:1[/tex]

Let the measure of YP and PS are 2x and x.

It is given that the measure of YP is 8.

[tex]2x=8[/tex]

[tex]x=\dfrac{8}{2}[/tex]

[tex]x=4[/tex]

[tex]PS=4[/tex]

Now, the measure of YS is:

[tex]YS=YP+PS[/tex]

[tex]YS=8+4[/tex]

[tex]YS=12[/tex]

The measure of median YS is 12 units. Therefore, the correct option is (a).

Answer:

B

Step-by-step explanation:

4x=3y

x/y=3/4

Just like the photo I attached

If 4x=3y, then 3/4 is the ratio of x to y in the simplest form. Option B is correct.

The ratio of x to y can be determined by dividing both sides of the equation 4x = 3y by y:

4x/y = 3y/y

4x/y = 3

To express the ratio of x to y in simplest form, we divide both sides of the equation by 4:

x/y = 3 / 4

Therefore, the ratio of x to y in simplest form is 3/4. option B is correct.

Answer:

[tex]h=25[/tex]

Step-by-step explanation:

From the question we are told that:

Velocity [tex]v=40fts[/tex]

The height h function

 [tex]\large h=-16t^2+40t[/tex]

Generally time t is mathematically given by

 [tex]h'=-32t+40[/tex]

 [tex]-32t+40=0[/tex]

 [tex]t=\frac{40}{32}[/tex]

 [tex]t=1.25[/tex]

Therefore  the ball's maximum height is given as

  [tex]\large h=-16(1.25)^2+40(1.25)[/tex]

 [tex]\large h=-16(1.25)^2+40(1.25)[/tex]

 [tex]h=25[/tex]

Answer:

18.75%

Step-by-step explanation:

Given that

There is a group of 32 pupils

3 play the flute only

13 play the piano only

And, 10 play neither instrument

We need to find out the probability the student plays both instruments

So

= (32 - 13 - 10 - 3) ÷ 32

= 6 ÷ 32

= 0.1875

= 18.75%

Answer:

6/32 or 3/16

Step-by-step explanation:

13 add 10 add 3 = 26

32-26=6

the total amount of children is 32 so the number is 6/32

you can then simplify it to 3/16

110=4t+90(being vertically opposite angles)

110-90=4t

20/4=t

5=t

Answer:

Hello! answer: t = 5 degrees

Step-by-step explanation:

these are vertical angles meaning they will have the same measure! 4 × 5 = 20 and 20 + 90 = 110 therefore t = 5 HOPE THAT HELPS!

Answer: We need 2.5 quarts of yellow paint.

Step-by-step explanation:

As per given, The ratio of blue paint to yellow paint is [tex]\frac34: \frac{5}{6}[/tex].

[tex]=3\times6:5\times4\\\\=18:20\\\\ =9:10[/tex]

Total green paint = [tex]4\frac34[/tex] quarts

Quantity of yellow paint required = [tex]\frac{10}{9+10}\times4\frac34[/tex]

[tex]=\frac{10}{19}\times\frac{19}{4}\\=\frac{5}{2}\\=2.5\ $$ quarts$$[/tex]

Hence, We need 2.5 quarts of yellow paint.

Answer: [tex]7,5.66,39^{\circ}[/tex]

Step-by-step explanation:

Given

[tex]IJ=9\\\angle I=51^{\circ}[/tex]

from figure, we can write

[tex]\Rightarrow \sin 51^{\circ}=\dfrac{HJ}{9}\\\\\Rightarrow HJ=9\sin 51^{\circ}=6.99\approx 7[/tex]

[tex]\Rightarrow \cos 51^{\circ}=\dfrac{HI}{9}\\\Rightarrow HI=9\cos 51^{\circ}\\\Rightarrow HI=5.66[/tex]

In right angle trianle, the sum of the remaining two angles is [tex]90^{\circ}[/tex]

[tex]\therefore 51^{\circ}+\angle J=90^{\circ}\\\Rightarrow \angle J=90^{\circ}-51^{\circ}\\\Rightarrow \angle J=39^{\circ}[/tex]

Answer:

$798

Step-by-step explanation:

Jack invested $7100 compounded continuously at an interest rate of 3⅝% which is 0.03625

Formula for future value of continuous compounding is;

FV = PVe^(rt)

Where;

FV is future value

PV is present value

r is interest rate

t is time

After 19 years;

FV = 7100 × e^(0.03625 × 19)

FV = $14137.697

Henry invested $7100 compounded monthly at an interest rate of 3⅜% which is 0.03375.

Formula for FV of monthly compounding is;

FV = PV(1 + i)^(n)

FV = 7100(1 + 0.03375)^(19)

FV = $13339.922

Thus, amount Jack has more than Henry = 14137.697 - 13339.922 = $797.775

Approximating to the nearest dollar gives $798
