Answer:

y=5.72

Step-by-step explanation:

Let's solve your equation step-by-step.

y−1.02=4.7

Step 1: Add 1.02 to both sides.

y−1.02+1.02=4.7+1.02

y=5.72

Answer: y=5.72

Step-by-step explanation:

4.7 plus 1.02 equals 5.72

5.72 minus 1.02 equals 4.7

We know that, Congruent Triangles always have same size, angles and shape, just then only they are congruent to each other, by various criterions such as

1.) SAS 2.) AAS 3.) RHS 4.) SSS 5.) ASA

so the correct option is D.)

D.) size and shape

Answer:

Without the math: 65 hours is 5 half-lives

13 hrs = 1/2

26 hrs = 1/4

39 hrs = 1/8

65 hrs = 1/32

(1/2)^5 = 1/32

400 mg / 32 = 12.5 mg   that is, after 5 half-lives

Answer:

m = 5

Step-by-step explanation:

distance traveled D= 16m^2+100 miles

speed, S= 8m+10 mph

time taken, T = 2m hours

We know that  D = S×T

⇒ 16m^2+100 = (8m+10)× 2m

⇒ 16m^2+100 = 16m^2+ 20m

⇒ 20m = 100

⇒ m = 5

Therefore, the value of m is 5

Answer:

[tex] 426.96 \: {km}^{2} [/tex]

Step-by-step explanation:

Area of the shaded region = Area of triangle with base 40 km and height 27 km - Area of circle with radius (12/2) 6 km.

[tex] = \frac{1}{2} \times 40 \times 27 - 3.14 \times {(6)}^{2} \\ \\ = 20 \times 27 - 3.14 \times 36 \\ \\ = 540 - 113.04 \\ \\ = 426.96 \: {km}^{2} [/tex]

Answer:

Cone: You need the radius and height of the cone.

Cylinder: You need the radius and height the cylinder.

Sphere: You only need the radius of the sphere.

Step-by-step explanation:

For a lot of object shapes height and radius play a large role, the sphere is an outlier because of it's for a lack of a better word, spherical shape.

Answer:

C. Isosceles

E. Equilateral

F. Scalene

D. Right angled

Answer:

In(8x)=[In]8 + [In]x

Step-by-step explanation:

By product rule:

[tex]In(8x)=[In]8 + [In]x[/tex]

Answer:

C

Step-by-step explanation:

If you divide 1.65 by 6 you'll get 0.275 so then you'll add d+6n to get d+6 and then you'll solve the question for 6n and you'll get 1.65

Answer:

x=32, x=0

Step-by-step explanation:

[tex](x-16)^2=256[/tex]

Take the square root of both sides

[tex]\sqrt{ (x-16)^2}=\±\sqrt{256}\\x-16=\±16[/tex]

x=16+16 or x=16-16

Therefore, x=32 or x=0

I hope this helps!

Answer:

x=32 and x=0

Step-by-step explanation:

Answer:

(a+b)(a+b)

=a^2 + ab + ab + b^2

=a^2 + 2ab + b^2

Answer:

(a+b)² = ( a +b ) (a + b )

= a² + b² + 2ab

Answer:

D

Step-by-step explanation:

Two numbers are multiplied together.

5 * 2/3

When you take the log, you get

log(5) + log(2/3)

log 2/3 is raised to the x power.

log(5) + log(2/3)^x                    

The x is a power and it can be taken down and multiplied by log(2/3)

log(5) + x log(2/3)

Answer:

D. log(5) + x • log(2/3)

Answer:

Mean = 4

Step-by-step explanation:

Mean = (Sum of all numbers)/(How many numbers there are)

There are 3 numbers

Mean = (5 + 4.5 + 2.5)/3

Mean = 12/3

Mean = 4

Answer:

[tex] \frac{5 + 4.5 + 2.5}{3 } = \frac{5 + 7}{3} = \frac{12}{3} = 4[/tex]

Answer:

9.304

Step-by-step explanation:

company wishes to estimate the mean monthly electric bill. If the standard

deviation is $400, how large a sample is required to estimate the mean electric bill to within $100

with 98% confidence?

Sample size, n = (Zcritical * σ) ÷ ME

σ = standard deviation ;

ME ≥ margin of error

α = 98% ; At 98% confidence level ;Zcritical = 2.326

n ≥ (2.326 * 400) / 100

n ≥ 930.4 / 100

n ≥ 9.304

n = 10

Answer: 1.65f

Step-by-step explanation:

Last year's admission fee = f

Percentage Increase in the admission fee = 65%

New admission fee will be the addition of last year's admission fee and the increase in the admission fee. This will be:

= f + (65% × f)

= f + (65/100 × f)

= f + (0.65 × f)

= f + 0.65f

= 1.65f

The new admission fee is 1.65f
