6m +7n +5т — Зm

Step-by-step explanation:

It is given that,

A building is 34 inches wide. Its 14 inches is concrete, 12 inches is brick, and 8 inches is limestone. We need to find the fraction of the wall is brick.

A fraction is in the form of x/y. y is total value and x is a part of y.

Here, 12 inches is brick. So, its fraction is :

[tex]F=\dfrac{12}{34}=\dfrac{6}{17}[/tex]

So, fraction of [tex]\dfrac{6}{17}[/tex] is the wall which is brick.

Answer: x > 8

2x - 7 > 9

2x > 9+7

2x > 16

2x / 2 > 16 / 2

x > 8

Leigh uses  [tex]\frac{1}{6}[/tex] of full bottle of hot sauce

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given,

A bottle of hot sauce is 3/4 full.

Leigh uses 2/9 of the contents of the hot sauce bottle for lunch.

Therefore

How much of a full bottle of hot sauce did Leigh use for lunch = [tex](\frac{3}{4}).(\frac{2}{9})[/tex]

= [tex]\frac{1}{6}[/tex]

Hence, Leigh uses  [tex]\frac{1}{6}[/tex] of full bottle of hot sauce

Answer:

D) 0

Step-by-step explanation:

Remainder is zero as 10 is fully divisible by 2.

Proof:

Correct choice is D) 0

Answer:

Given = A △ABC in which D and E are the mid-points of side AB and AC respectively. DE is joined .

To Prove : DE || BC and DE = 1 / 2 BC.

Const. : Produce the line segment DE to F , such that DE = EF. Join FC .

Proof : In △s AED and CEF, we have

AE = CE [∵E is the mid point of AC]

∠AED = ∠CEF[vert. opp.∠s]

and DE = EF [by construction]

∴ △AED ≅ △CEF [by SAS congruence axiom]

⇒ AD = CF ---(i)[c.p.c.t.]

and ∠ADE and ∠CEF ---(ii) [c.p.c.t.]

Now, D is the mid point of AB.

⇒ AD = DB ---(iii)

From (i) and (iii), CF = DB ---(iv)

Also, from (ii)

⇒ AD = || FC [if a pair of alt. int. ∠s are equal then lines are parallel]

⇒ DB || BC ---(v)

From (iv) and (v), we find that DBCF is a quadrilateral such that one pair of opposite sides are equal and parallel.

∴ DBCF is a ||gm

⇒ DF || BC and DF = BC [∵opp side of ||gm are equal and parallel]

Also, DE = EF [by construction]

Hence, DE || BC and DE = 1 / 2 BC

Answer:

y = [tex]\frac{33}{x}[/tex]

Step-by-step explanation:

Use the inverse relationship equation, y = [tex]\frac{k}{x}[/tex]

Plug in what we know to solve for k:

11 = [tex]\frac{k}{3}[/tex]

33 = k

Plug 33 in as k to find the equation:

The equation will be y = [tex]\frac{33}{x}[/tex]

Step-by-step explanation:

66. Δy = -3.4 Δx

Δy/Δx = -3.4

The slope of the line is -3.4. Slope-intercept equation of the line is:

y = -3.4x + b

Plug in the given point to find b:

2 = -3.4(4) + b

b = 15.6

Therefore, the equation is y = -3.4x + 15.6.

Use the equation to find the y coordinates.

[tex]\left[\begin{array}{cc}x&y\\-4&29.2\\4&2\\6&-4.8\\18&-45.6\end{array}\right][/tex]

68. Repeat the same steps as 66.

Δy = -1.7 Δx

Δy/Δx = -1.7

The slope of the line is -1.7. Slope-intercept equation of the line is:

y = -1.7x + b

Plug in the given point to find b:

3 = -1.7(-7) + b

b = -8.9

Therefore, the equation is y = -1.7x − 8.9.

Use the equation to find the x or y coordinates.

Answer:

A

Step-by-step explanation:

The standard form of an explicit formula for a geometric sequence is given by:

[tex]x_n=a(r)^{n-1}[/tex]

Where n is the nth term, a is the initial term, and r is the common ratio.

We are given that the first term is 5. Hence, a = 5.

Also, we are given that the second term is -10. Therefore, the common ratio r is -2, because we multiply the first term by -2 to acquire -10.

Substituting yields:

[tex]x_n=5(-2)^{n-1}, n\geq 1, n\in\mathbb{Z}[/tex]

(Note: Z means the set of all integers. This is required because the term number can only be positive starting from one. For instance, we can't have the 0th term or the 1.5th term.)

In conclusion, the answer is A.

The 4 in 45 is 40 because it is in the tens place, 4 times 10= 40.  The 5 is 5 becasue it's in the ones place.  :)

It's just place value:

Answer:

The first digit i.e. 4 is called the tens' place. Here, there are 4 tens. The last or right digit i.e. 5 is called the ones' place. Therefore, in the number 45 = 4 tens plus 5 ones = 40 + 5 = 45

Step-by-step explanation:

By multiplying both the binomial and the trinomial given, we obtain a polynomial which contains both as factors. We notice as well that the given trinomial doesn't have 3 as a root (so there is no multiple root x = 3 in the product we obtain:
