Answer: 15

Step-by-step explanation:

Each side of the smaller triangle is scaled up by 2.5.

4x2.5=10

8x2.5=20

6x2.5=15

Answer:

BD = 2.4 units

AB = 4 units

Step-by-step explanation:

using the Pythagorean theorem:

3²-1.8² = BD²

BD² = 5.76

BD =  2.4

2.4²+3.2² = AB²

AB² = 16

AB = 4

This  has to be determined by pythagorian theorem. Hence the value of AB= 4 units and BD= 2.4 units.

Given: AD = 3.2 units

          BC  = 3 units

          CD  = 1.8 units

Find : AB =? units

          BD=? units

As we know that ,

By the formula of  pythagorian theorem,

Let be a ΔABC,

                     [tex]\bold{(AB)^{2} = (BC)^{2} +(AC)^{2}}[/tex]

From the above formula now  determined  the value of AB and BD,

Firstly , find the value of BD

In ΔBDC, by applying pythagaorian theorem,

[tex]\bold{(BC)^{2} = (BD)^{2} +(DC)^{2}}[/tex]                                                         ...(1)

Here, BC  = 3 units and CD = 1.8 units

Now put the values of  BC and CD  in (1),

[tex]\begin{aligned}(3)^{2} &=(BD)^{2}+(1.8)^{2}\\9&=(BD)^{2}+3.24\\9-3.24&=(BD)^{2}\\5.76&=(BD)^{2}\\\sqrt{5.76} &=BD\\\bold{BD&= 2.4}\:units\end{aligned}[/tex]                                                         ...(2)

Now find the value of AB,

In ΔABD, by applying pythagorian theorem,

[tex]\bold{(AB)^{2}=(AD)^{2} + (BD)^{2} }[/tex]                                                       ...(3)

Here, AD=3.2 and from (2) BD=2.4

By putting values in (3) ,

[tex]\begin{aligned}(3.2)^{2} +(2.4)^{2}&=(AB)^{2}\\10.24+5.76&=(AB)^{2}\\16&=(AB)^{2}\\\sqrt{16} &=AB\\\bold{AB&= 4}\:units\end{aligned}[/tex]

Therefore,the values of AB=4 units and BD= 2.4 units.

Step-by-step explanation:

Answer:

11

Step-by-step explanation:

17+9+11+7 divided by 4

because the mean= sum of the terms divided by the number of terms

the sum= 17+9+11+7=44

the number of terms= 4

44 divided by 4= 11

Answer:

(17+9+11+7) / 4 mean is an average

it is equal to the sum of the elements divided by the number of elements

the sum is 44

the number of elements is 4

the mean is the average= 44/4=11

Answer:

3

Step-by-step explanation:

g(x) = f(x) + k, is true for all values of x.

At x = 0, f(x) = 2

At x = 0, g(x) = 5

Therefore, at x = 0

=> g(x) = f(x) + k

=> 5 = 2 + k

=> 3 = k

Since, the given relation is true for all real values of x, k is independent of x. Thus k = 3, for every value of x

Answer:

10×10.70=$107 spent on cups

107-293=$186 spent on the jacket

so for the jackets 186= how many they got and much each cost.

u=186÷x

or 186=u the cost of each × x how many they got.

Step-by-step explanation:

[tex]45 + 45 + x = 180 \\ 90 + x = 180 \\ x = 180 - 90 \\ x = 90[/tex]

Answer:

y = (1/3)x -1

Step-by-step explanation:

y = mx + b

Here, m = 1/3 ;  y -intercept (b) = -1

y = (1/3)x -1

Answer:

Step-by-step explanation:

f(x)  = 7x³ - x² - x - 5

To test if (x-1) is a factor, calculate f(x) for x=1:

f(1) = 7·1³ - 1² - x - 5 = 0

Since f(1) = 0, (x-1) is a factor.
