Answer:

D) three more than his age doubled

Step-by-step explanation:

Answer:

53/20

Step-by-step explanation:

First convert 3 2/5 into 17/5

Now we need a like denominator for both fractions

20 works

lets convert 17/5 into 68/20

and 3/4 can turn into 15/20

68/20 - 15/20

53/20

Answer:     53/20   or   2  13/20

Step-by-step explanation:

hope this helps

Answer:

Tan(Ф) = [tex]\frac{12}{5}[/tex]

Step-by-step explanation:

Tan(Ф) = [tex]\frac{opposite}{adjacent}[/tex]

Tan(Ф) = [tex]\frac{12}{5}[/tex]

Hope this helps!

Step-by-step explanation:

these angles will add to 90 deg

90 = 22 + 2x

solve for x

Answer:

x = 34°

2x = 68°

Step-by-step explanation:

Both angles are complementary (add up to the sum of 90°), so we can say;

22 + 2x = 90°

2x = 90 - 22

2x = 68

x = 68 / 2

x = 34°

Furthermore:

If you have to find the value of 2x it would be 68, since

2x = 2(34) = 68°

Hope this helps!

Answer:

247.21

Step-by-step explanation:

equation for height :  c= a2 + b2

4.82 + 9.32

≈10.46566

equation for surface area: A=5 /4tan(54°)a2+5a /2h2+(atan(54°) /2)2

5 /4·tan(54°)·72+5·7 /2·7.972+(7·tan(54°) /2)2

≈247.21018

round to nearest hundredth: 247.21

[tex]P = 154\\a = 2b + 2[/tex]

a = ?; b = ?

[tex]P = 2(a + b) = 2(2b + 2 + b) = 2(3b + 2) = 6b + 4[/tex]

[tex]154 = 6b + 4\\6b = 154 - 4\\6b = 150\\b = 150 : 6\\b = 25[/tex]

[tex]a = 2b + 2 = 2 * 25 + 2 = 50 + 2 = 52[/tex]

Answer: 25 and 52 m.

Answer:

7 2/15

Step-by-step explanation:

Second option

Answer:

7 2/15.

Step-by-step explanation:

First in order to subtract you have to find the LCM/ least common multiple which is 15 as 5x3 = 15 and 3×5= 15, and so then with the new denominator being 15 you have to solve for the numerator, and so 3 goes into 15 5 times and 2x5= 10 and 5 goes into 15 3 times, so 4x3 = 12. So then you are left with 16 12/15 - 9 10/15 which will then be 7 2/15.

D:  -38, when added to 38, will result in a sum of 0.

Answer:

3.8m

Step-by-step explanation:

If A, E and B lie on a straight line segment. C, D and B lie on a straight line segment, based on their similarities,

AB/CB = BE/BD

Given

BD = 3m,

CD = 12m

AB = 19m.

CB = CD+BD

CB = 12+3 = 15m

On substituting

19/15 = BE/3

Cross multiply

15BE = 19×3

15BE = 57

BE = 57/15

BE = 3.8m

Hence the length of BE is 3.8m

Answer:

9

Step-by-step explanation:

Answer:

6x+16+20=90

6x+36=180

6x=180-36

6x=144

x=144/6

x=26°

Answer:

About 525 times.

Step-by-step explanation:

You have a 5 in 8 chance of getting a consonant originally. You should try to find an equal ratio except with 840 as the second number. As of now it's      5/8 = ?/840

8 is a factor of 840 and if you divide 840 by 8 you get 105. If you actually think about it 105/840 would be an equal ratio to 1/8 so you multiply 108 by 5 to get 525.

Answer:

11 inches

Step-by-step explanation:

We know that [tex]SA=4\pi r^2[/tex]. We know that [tex]SA=379.94[/tex] and that [tex]\pi\approx3.14[/tex]. We solve for [tex]r[/tex]: [tex]379.97=4\times3.14\times r^2[/tex]

[tex]r^2=30.25[/tex]

[tex]r=5.5[/tex]

Since [tex]d=2r[/tex], the diameter of the sphere is 11 inches.

Answer:

1) b⁵⁴

2) 7⁷

Step-by-step explanation:

When you have an exponent raised to an exponent, like in #1, you simply multiply the exponents.

When you are dividing two numbers with exponents and they have the same base, like in #2, you subtract the denominator exponent from the numerator exponent.

Hello~

All you have too do is add!

27+6+98=

Simplify

27+6=33

Add again

33+98= 131

So its 131!

Answer:

  $7.50

Step-by-step explanation:

The monthly interest rate is 3%/12 = 1/4%. The dollar amount of interest earned in 3 months is ...

  I = Prt = $1000(0.0025/mo)(3 mo) = $1000(0.0075) = $7.50

Step-by-step explanation:

the longer diagonal is =

√(40²+70²+2(40)(70)cos 36°)

= √(1600+4900+5600(0.8))

= √ 6500 + 4530

= √11,030

= 105 ft

Answer:

1= 33

2= 90

3= 57

Step-by-step explanation:

the agle thats 57° is alternate interior to ∠3 so ∠3= 57

so 33+ 57= 90 ⇒ 180- 90= 90 ⇒ ∠2= 90

57+ 90= 147⇒ 180- 147= 33

Answer:

(2, 4)

Step-by-step explanation:

"What is the solution of this system of equations?"

Substitute 3x - 2 for y in the second equation, obtaining:

3x - 2 - 2 = x

Consolidate like terms:  subtract x from both sides and add 4 to both sides:

2x = 4.  Thus, x = 2.  Substituting 2 for x in the first equation, we get:

y = 3(2) -2 = 4.

Thus, the solution is (2, 4)

Answer:

x = 3

Step-by-step explanation:

According to Euclidian theorem (x+9)^2 = 18*8

(x+9)^2 = 144 find the root for both sides

x + 9 = 12 subtract 9 from both sides

x = 3
