Answer:

17.5

Step-by-step explanation:

19+7÷2-5

Order of operations says to multiply and divide before adding and subtracting.

19+3.5-5

Then go from left to right.

22.5-5=17.5

Answer:

4 1/10 or 4.1

Step-by-step:

1 1/2+2 3/5

convert both into an improper fraction

1 1/2 as an improper faction= 3/2

then

2 3/5 as an improper fraction= 13/5

so now we can work the question out as

3/2 + 13/5

which is 41/10

41/10 is an improper faction which is also equal to

4 1/10

Hope this helped you- have a good day bro cya)

The mass in ounces will be 4.40925 oz.

A unit conversion expresses the same property as a different unit of measurement.

Given that, the mass of a competition Frisbee is 125g

1 oz = 28.349 g

1 g = 1/28.349 oz

125 g = 125*1/28.349 oz

125 g = 4.40925 oz.

Hence, The mass in ounces will be 4.40925 oz.

Answer:

72-12k

Step-by-step explanation:

Our information:

Speed=12mph

Distance=x

Time=K less than 6 hours

Using the distance triangle, (Distance over speed and time,) We can use this equation.

TxS=D

12x(6xk)=D

72-12k

The number of miles she can travel if she runs for k less than 6 hours will be 12k-172.

Distance is a measurement of the separation between two things or places. When we talk about distance, we're talking about a physical length or an estimate based on other physics or practical usage factors.

It is given that,

Speed=12mph

Distance=x

Time, t= (K - 6) hours

The distance for the given condition is,

d = v × t

d = 12  (K - 6)

d = 12k - 72 miles

Thus, the number of miles she can travel if she runs for k less than 6 hours will be 12k-172.

Answer:

x = - 5, - 6

Step-by-step explanation:

x^2 + 11x + 30 = 0

x^2 + 5x + 6x + 30 = 0

x ( x + 5 ) + 6 ( x + 5 ) = 0

( x + 6 ) ( x + 5 ) = 0

x + 6 = 0

x = - 6

x + 5 = 0

x = - 5

Step-by-step explanation:

the second option 1/(125n¹²)

why ?

when we have the exponent of an exponent, we can multiply the exponents.

so, 4×-3 = -12

a negative exponent means 1/... (with the corresponding positive exponent in the denominator).

and an exponent of the multiplication of factors means that the exponent is to be used for every factor in the multiplication.

so, the exponent -3 has to be applied to 5 and to n⁴.

this gives us 5^‐3 and n^-12 as factors.

the result is 1/(5³) × 1/(n¹²).

and that is the mentioned result above.

Answer:

Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6.

Answer: $2500

Step-by-step explanation:

4% of what number = 100

0.04 x ? = 100

divide both sides by 0.04

? = 100/ 0.04

  = $2500

Step-by-step explanation:

option A is correct

we will add 5 to both the sides

→ 1/8x - 5 = 3

→ 1/8x = 8

than we will multiply 8 to both the sides

→ x = 8×8 = 64.

Answer:

  220%

Step-by-step explanation:

The percentage change is computed by ...

  % change = ((new value)/(old value) -1) × 100%

  = (800/250 -1) × 100% = (3.2 -1) × 100%

  = 220%

The increase was 220%.
