Which expression is equivalent to (2^−1⋅2^3) ^−1 ?

a) 16

b) 1/16

c) 1/2

d) 1/4

Answer:

It should be 25.

Step-by-step explanation:

one Triangle is 5 times the size of the other triangle

length of 5 x 5 = 25

width of 3 x 5 = 15

Answer:

C

Step-by-step explanation:

the answer is c because there is more then one y value for 5

Answer:

the perimeter 126 cm

Answer:

each apple is £ 1.80

Step-by-step explanation:

i first multiplied the cost for one pear by 7, to get how much money was spent on pears out of the 12.70.

Then i took the remaining money and divided it by 2 to get how much each apple costs.

Answer:

1.80

Step-by-step explanation:

1) Price of Pears

[tex]1.30 * 7 = 9.10[/tex]          formating: 1.30*7 = 9.10

2) Price of Apples

[tex]12.70 - 9.10 = 3.60[/tex]          formating: 12.70-9.10 = 3.60

3) Price of Apples/Kg

[tex]\frac{3.60}{2} = 1.80[/tex]          formating: 3.60/2 = 1.80

Answer: 3x - 1

Step-by-step explanation:

let x = the price

3x would be three times the price

now minus one dollar would get:

3x - 1

Answer:

Step-by-step explanation:

Here,

<BAC + <BAE = 180° [Since supplementary angles]

=> 52° + <BAE = 180°

=> <BAE = 180° -52°

=> <BAE = 128° (Ans)

Answer:

Step-by-step explanation:

Answer:

[tex]0.625kg[/tex]

Step-by-step explanation:

we are given half-life of PO-210 and the initial mass

we want to figure out the remaining mass after 420 days

in order to solve so we can consider the half-life formula given by

[tex] \displaystyle f(t) = a {0.5}^{t/T} [/tex]

where:

since it halves every 140 days our T is 140 and t is 420. as the initial mass of the sample is 5 our a is 5

thus substitute:

[tex]\displaystyle f(420)=5\cdot{0.5}^{420/140}[/tex]

reduce fraction:

[tex]\displaystyle f(420)=5\cdot{0.5}^{3}[/tex]

By using calculator we acquire:

[tex]\displaystyle f(420)=0.625[/tex]

hence, the remaining sample after 420 days is 0.625 kg

solution given;

let

AB=a

AC=b=30ft

AB=c=20ft

<A=115°

By using Cosine rule.

a²=b²+c²-2bc cos angle

a²=30²+20²-2*30*20 Cos 115°

a²=1807.1419

a=√[1807.1419]

a=42.51

Side A is 42.51ft.

Again

Cos B=[tex] \frac{a²+c²-b²}{2ac} [/tex]

Cos B=[tex] \frac{42.51²+20²-30²}{2*42.51*20} [/tex]

Cos B=0.7687

<B=Cos -¹(0.7687)

<B=39.46°

Angle B is 39.46°

Answer:

b

Step-by-step explanation:

Answer:

Firs property used : Quotient Property

           [tex]log_b(\frac{X}{Y} ) = log_bX -log_bY[/tex]

   [tex]log_b(\frac{\sqrt[3]{x} }{36y^2} ) = log_b(\sqrt[3]{x}) - log_b(36y^2)[/tex]

Second property used : Product Property

          [tex]log_b(XY) = log_bX + log_b Y[/tex]

    [tex]log_b(\sqrt[3]{x}) - log_b(36y^2) = (log_b(\sqrt[3]{x}) - [log_b36 + log_by^2)[/tex]

Third property used : Power Property

                 [tex]log_b \sqrt[n]{X} = log_b(X)^{\frac{1}{n}} = \frac{1}{n} log_b X[/tex]

 [tex](log_b(\sqrt[3]{x}) - [log_b6^2 + log_by^2) = \frac{1}{3} log_bx - 2log_b 6 - 2log_by[/tex]

Fully expanded form:

                   [tex]log_b(\frac{\sqrt[3]{x} }{36y^2} ) = \frac{1}{3} log_b x-2log_b6-2log_by[/tex]

Answer:

  A.  10 units

Step-by-step explanation:

The y-intercept of f(x) is f(0) = -9.

The y-intercept of g(x) is g(0) = g(1)/2 = 1.

The distance between these points is ...

  1 -(-9) = 10 . . . units

__

We notice that the common ratio of the table values of g(x) is 4/2=2, so the value for x=0 will be a factor of 2 less than the value for x=1.

Step-by-step explanation:

Answer:

A. 10.4 mph

Step-by-step explanation:

26÷2.5=10.4

Double checking your answer:

If she does 10.4 miles in an hour, she can get 20.8 in two hours

then you add half of how much she can go in an hour which is 5.2 (10.4÷2)

you add it together, and you will get 26 miles in total

(20.8+5.2=26)

Answer:

n = 34

Step-by-step explanation:

2{(24- ( 3 + 4)) =n

2{(24 - 7) =n

2 x 17 = n

34 = n

swap the sides

n = 34
