Can someone please help with number 5 and 6.

Answer:

42

Step-by-step explanation:

S1 let a and b be the digits of the number

so a 2 digit number cab written as - 10×a + b

eg - 68 as 6×10 + 8

S2 ) according to ques

a + b = 6    - eqn 1

(10×a + b) - (10×b + a) = 18

9×a - 9×b = 18

a - b = 2   - eqn 2

S3)from eqn 1 and eqn 2

we get a = 4 and b = 2

hence number is 42

Answer:

x ≥ 15

Step-by-step explanation:

first we will subtract 10 from both sides

we get x/3 ≥ 5

then we will multiply both sides by 3

and final answer will be x ≥ 15

Step-by-step explanation:

answer is option D

because you can divide them like

[tex] \frac{2}{10} = \frac{1}{5} \\ \\ \frac{4}{20} = \frac{1}{5} \\ \\ \frac{6}{30} = \frac{1}{5} \\ \\ \frac{8}{40} = \frac{1}{5} [/tex]

so the option is D

Step-by-step explanation:

that back and forth between the different scales is the only task challenge. you need to focus to not mix things up.

so if I understand correctly, we should use the conversion rate of 1 kg = 2.2 pounds.

she should add 1 quart of water to every 26.7 pounds of concrete mix.

80 kg = 80×2.2 pounds = 176 pounds.

we need as many quarts of water as there are units of 26.7 pounds in 176 pounds.

176/26.7 = 6.5917603... quarts of water needed.

that would be rounded 6.6 quarts of water.

Answer:

In mathematics, a transformation is a function f (usually with some geometrical underpinning) that maps a set X to itself, i.e. f : X → X. In other areas of mathematics, a transformation may simply refer to any function, regardless of domain and codomain.

Step-by-step explanation:

15 x 64 = 15 x (60 + 4)

= (15x60) + (15x4)

= 900 + 60

= 960

Step-by-step explanation:

You basically have to divide your number from a prime factor until your result is 1

For example

12

you divide it from the lowest prime number possible, for in this case, 2

12/2 = 6 and you can set aside 2 for now

You do the same thing and you divide it by 2

6/2 = 3 and set aside 2

Now 3 isn't divisible by 2 so you'll find another number, for in this case 3

3/3 = 1

your set side numbers are now 2,2,3

so you'll find out 12 = 2x2x3 as a product of it's prime factors

how ever you cant divide it by 4 or 6 since they aren't prime factors as they are divisible by other numbers

Answer:

Option(A) [tex]4^{\frac{5}{8}}[/tex] is equivalent to [tex]$\frac{4^{\frac{7}{3}}}{4^{\frac{1}{4}}}$[/tex]

Step-by-step explanation:

Given:

[tex]$\frac{4^{\frac{7}{3}}}{4^{\frac{1}{4}}}$[/tex]

To simplify the expression

Using the exponent rule,

[tex]$\frac{x^{a}}{x^{b}}=x^{a-b}$[/tex]

[tex]$\frac{4^{\frac{7}{3}}}{4^{\frac{1}{4}}}$[/tex][tex]=4^{\frac{7}{8}-\frac{1}{4}}[/tex]

[tex]=4^{\frac{5}{8}}[/tex]

The correct answer option is (A) [tex]4^{\frac{5}{8}}[/tex]

Hi :)

The volume of a sphere is

V = 4/3 (pi) r^3

Supposing "length" as diameter

We can take the radius

2.40/2

1.2 is the radius of the sphere.

Inserting the radius into the formula

V = 4/3 (pi) 1.2^3

The volume is aproximately 7.24cm^3

Answer:

$56.50

Step-by-step explanation:

950=500+450

[tex]500 \times .05 = 25[/tex]

And

[tex]450 \times .07 = 31.5[/tex]

Add the sum and you get 56.5

Answer:

144$

Step-by-step explanation:

So first you could need to find the x and y intercepts.

So the x intercept can be found why y is zero and vice versa.

so your graph would go through the points (0,5) and (2.5,0)

When expressions are equivalent, the expressions have the same value. The number x is 42, because 10 less than 42 is 32.

The number is represented as x

10 less than x is represented as x - 10

From the question, we understand that the 10 less than x is equivalent to 32.

So, the expression becomes

[tex]x - 10 =32[/tex]

Collect like terms

[tex]x = 32 + 10[/tex]

Add 32 and 10

[tex]x = 42[/tex]

Hence, the number (x) is 42

Answer:

the answer is The second one

My calculator shows that

(2.1)/(1.488) = 1.41129

which is approximate. If you want the result to two decimal places, then it would be 1.41 and not 1.40

Try 1.41 and it should work out, assuming your teacher wants two decimal places.
