Answer:

  D)  infinitely many

Step-by-step explanation:

There are infinitely many points on any portion of the number line. The shading on the graph indicates all numbers less than or equal to 8 are solutions. There are infinitely many such numbers.

Answer:

-2(7) + -2(5g)

Step-by-step explanation:

Using the distributive property we can confirm that:

-2(7) + -2(5g) = -2(7+5g)

Answer:

−14−10g

Step-by-step explanation:

First, solve the product:

-2 ⋅ 7 - 2 ⋅ 5g

Multiply -2 times 7 to -14.

So, the equivalent expression would be:

-14 - 2 ⋅ 5g = -14 - 10g

-14 - 10g

Answer:

5

Step-by-step explanation:

Since the two lines are parallel, they must have the same slope. This means that the slope of green line must be 5 just like the red line. You can also use the slope formula (rise/run) or change in y divided by change in x.

Answer:

B

Step-by-step explanation:

when it says -2 that means you go straight down

Answer:

B

Step-by-step explanation:

-2 in the equation is the y intercept and the slope is positive so graph B is the only possible answer

Answer:

2.4

Step-by-step explanation:

Because of AA Similarity, we have BDC is similar to FHG. We know that FH is 2/5 times BD so FG is 2/5 times BC which is 6*2/5 = 12/5 = 2.4

You just reverse the way you read the question.

1.

300 x 0.15 = 45

300 - 45 = 255

255 kids came to the party

//

2.

80 x 0.20 = 16

80 - 16 = 64

She got 64 items correctly

//

3.

50 x 0.28 = 14

50 - 14 = 36

36 pupils were present

//

4.

48 / 50 = 0.96

0.96 x 100 = 96.0%

96% joined the trip

//

5.

50 x 0.06 = 3

3 pupils are left handed

Answer:

x=50

Step-by-step explanation:

40+65+25+x=180

Combine like terms

130+x=180

x=50

(triangles = 180)

-9 in power means that the value is in fractional and the 10 base is multipied 9 times and put it on denominator.

8.6 = 86 x 10^-1

Let's multiply :

86 x 10^-1 x 10^-9

= 86 x 10^-10

= 86/10000000000

=0,0000000086

Note : if you don't know about how 10^-1 x 10^-9 returns 10^-10, it's because of exponential rules. If the base are same wuth each other, then just do the addition operation in the exponent like this :

10^(-1+(-9))

= 10^(-1-9)

=10^-10

Hope it helps :)

Answer:

one solution

Step-by-step explanation:

2( 4 + 1 0 ) = 8 +2 0   = 2 8 + 2 0

Subtract  

from both sides of the equation

Simplify  

Subtract  8  from both sides of the equation

Simplify

Divide both sides of the equation by the same term

Simplify

Solution   = − 5 /2

Answer:

[tex]A=2833.71\ cm^2[/tex]

Step-by-step explanation:

Given that,

The height of the cylinder, h = 30 cm

The radius of the cylinder, r = 11 cm

We need to find the total surface area of the cylinder. The formula for the total surface area of the cylinder is given by :

[tex]A=2\pi rh+2\pi r^2\\\\A=2\pi \times 11\times 30+2\pi \times (11)^2\\\\A=2833.71\ cm^2[/tex]

So, the total surface area of the cylinder is [tex]2833.71\ cm^2[/tex].

Answer:

b. PHP 31,250.00

Step-by-step explanation:

Simple interest = principal × rate × time

Principal = PHP 25,000

Rate = 2.5%

Time = 10 years

Simple interest = principal × rate × time

= PHP 25,000 × 2.5% × 10

= 25,000 × 0.025 × 10

= 6,250

Simple interest = PHP 6,250

Investment after 10 years = principal + simple interest

= PHP 25,000 + PHP 6,250

= PHP 31,250

Investment after 10 years = PHP 31,250

Solution :

We have to find the largest fraction in each group.

a). [tex]$\frac{5}{6}$[/tex] and [tex]$\frac{29}{36}$[/tex]

    [tex]$\frac{5}{6}$[/tex]  →  when we divide the number 5 with 6, we get 0.833

    [tex]$\frac{29}{36}$[/tex] → when we divide 29 by 36, we get the value 0.805

Therefore, in this group, [tex]$\frac{5}{6}$[/tex] is the largest fraction.

b).  [tex]$\frac{5}{12}$[/tex] and [tex]$\frac{3}{8}$[/tex]

     [tex]$\frac{5}{12}$[/tex]  →  when we divide the number 5 with 12, we get 0.416

    [tex]$\frac{3}{8}$[/tex] → when we divide 3 by 8, we get the value 0.375

Therefore, in this group, [tex]$\frac{5}{12}$[/tex] is the largest fraction.

c).  [tex]$\frac{2}{5}$[/tex] and [tex]$\frac{19}{45}$[/tex]

     [tex]$\frac{2}{5}$[/tex] →  when we divide the number 2 with 5, we get 0.40

    [tex]$\frac{19}{45}$[/tex] → when we divide 19 by 45, we get the value 0.42

Therefore, in this group, [tex]$\frac{19}{45}$[/tex] is the largest fraction.

d).  [tex]$\frac{5}{7}$[/tex], [tex]$\frac{13}{14}$[/tex] and  [tex]$\frac{19}{21}$[/tex]

      [tex]$\frac{5}{7}$[/tex] →  when we divide the number 5 with 7, we get 0.714

    [tex]$\frac{13}{14}$[/tex] → when we divide 13 by 14, we get the value 0.928

    [tex]$\frac{19}{21}$[/tex]  → when we divide 19 by 21, we get the value 0.904

Therefore, in this group, [tex]$\frac{13}{14}$[/tex]  is the largest fraction.

The equivalent value of the expressions are solved by the exponents

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the exponential equation be represented as A

Now , the value of A is

A = 25ˣ

On simplifying , we get

A = ( 5 . 5 )ˣ

A = ( 25 )ˣ

And , A = 5ˣ . 5ˣ

From the laws of exponents , we get

mᵃ×mᵇ = mᵃ⁺ᵇ

A = 5²ˣ

A = 25ˣ

Hence , the expressions are ( 5 . 5 )ˣ = 5²ˣ = 5ˣ . 5ˣ = 25ˣ
