you multiply 80 x 4, then you get ur answer, 320.

Answer:

C. 320 (correct)

Step-by-step explanation:

If Samantha can type 40 words per minute, to find the number of words Samantha can type in 8 minutes, multiply 40 by 8.

40×8=320

Therefore, Samantha can type 320 words in 8 minutes.

Step-by-step explanation:

Answer: 6.68km/litre

Step-by-step explanation:

Distance(d) = 187km ( to 3 significant figures)

Petrol(p) = 28litres ( to 2 significant figures)

A number, x, rounded to 1 significant figure is 200

Write down the error interval for x

Calculating the lower and upper bound for both 'd' and 'p'

Upper bound 'd' = 187.5km

Lower bound 'd' = 186.5km

Upper bound 'p' = 28.5km

Lower bound 'p' = 27.5km

Therefore,

Petrol consumption (C) = d/p

Upper C = 187.5 / 28.5 = 6.57894

Lower C = 186.5 / 27.5 = 6.781818

Accuracy answer for C = (6.57894 + 6.781818) / 2 = 6.680379

= 6.68km/ litre ( to 3 significant figures)

To achieve a reasonable level of accuracy, the upper and lower bounds of P and D was used to calculate C, which was then averaged.

Using 3 significant figures ensure that we capture the C better, instead of early rounding.

Answer:

B.) 10.5

Step-by-step explanation:

Use ratios, but be careful.

AE/AD = AB/AC

14/18 = x/(x+3).

14x+42 = 18x

42 = 4x

x = 10.5

The value of x in the given figure is 10.5 so, option B.) 10.5 units is correct.

Suppose that we've got two quantities with measurements as 'a' and 'b'

Then, their ratio(ratio of a to b) a:b

or

[tex]\dfrac{a}{b}[/tex]

Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.

Using ratios;

AE/AD = AB/AC

14/18 = x/(x+3).

14x+42 = 18x

42 = 4x

x = 10.5

Thus, option B.) 10.5 units is correct.

The measures 3.1, 4.8, and 10.2 cannot be the side lengths of a triangle.

"It states that the sum of any two sides must be greater than the third side."

For given question,

we have been given the measures 3.1, 4.8, and 10.2  

We need to check whether given measures can be the side lengths of a triangle.

First we check whether the given measures obey triangle inequality or not.

3.1 + 4.8 = 7.9

7.9 < 10.2

This means, the measures 3.1, 4.8, and 10.2 do not obey triangle inequality

Therefore,  the measures 3.1, 4.8, and 10.2 cannot be the side lengths of a triangle.

Answer:

m∠C = 44°

Step-by-step explanation:

In ΔCDE,

m∠C=(4x−16) ∘

m∠D=(6x−1) ∘

m∠E=(4x−13) ∘ .

The sum of angles in a triangle = 180°

Step 1

We solve for x

m∠C + m∠D + m∠E

(4x−16)° + (6x−1)° + (4x−13)° = 180°

4x - 16 + 6x - 1 + 4x - 13 = 180°

4x + 6x + 4x -16 - 1 - 13 = 180°

14x - 30 = 180°

14x = 180+ 30

14x = 210

x = 210/14

x = 15

Step 2

Find m∠C

m∠C = (4x−16)°

m∠C = (4 × 15 - 16)°

m∠C = (60 - 16)°

m∠C = 44°

Answer:

Circumference of the circle = 34.54 inches

Step-by-step explanation:

Explanation

Given that diameter of the circle

                                    d = 11inches

The radius of the circle    

                                [tex]r = \frac{d}{2} = \frac{11}{2} = 5.5[/tex]

Circumference of the circle

                              = 2πr

                             = 2×3.14×5.5

                           = 34.54

Answer:3

Answer:

Step-by-step explanation:

p1=(2,4)   and p2=(5,6)

use slope formula to find the slope

[m=y2-y1 / x2-x1)]

m=6-4 / 5-2

m=2 / 3

use point-slope formula [y-y1=m(x-x1)] with either given point and work but  since they have a 5 and a 6 in the their answer use p2

y-6=2/3(x-5)

Answer:

-x+y= -14 (get this equation to where you can easily plug it in for a variable)

y= x -14

5x +6y =26 (plug the value above in for y and then solve)

5x + 6 (x-14) = 26 (use the distributive property)

5x +6x - 84 = 26 (combine like terms on the left side)

11x - 84 =26 (add 84 to both sides)

11x = 110 (divide both sides by 11 to isolate the x-variable)

x= 10 (this is the value for x. plug it into the easier equation and solve)

-(10) +y = -14

y= -4

(10, -4) (this is the solution for the system of equations)

Answer:

(-5, -8); the missing value is -8

Step-by-step explanation:

First, you need to simplify the given equation to isolate y

1: -3x + 7y = 5x + 2y (Given)

2: 7y = 8x + 2y (Add 3x to both sides)

3: 5y = 8x (Subtract 2y from both sides)

4: y = 8/5x (Divide both sides by 5)

Now, you can use this to solve for the missing y in value set (-5, y)

where y = 8/5x and x = -5,

y = 8/5(-5)

y = -8

so, the missing value is -8
