÷ 30

1 = 80

Answer:

t=2

Step-by-step explanation:

Start by subtracting 9 from both sides. You'll get 7-2t=3/2t. I made 3/2 a mixed number, so 1 1/2. You should have 7-2t=1 1/2t. Add 2t to both sides, because the 2t is negative. You should have 7=3 1/2t. Last step is to divide     3 1/2 into both sides. 7 divided by 3 1/2 is equal to 2, so t=2

Answer:

Step-by-step explanation:

24/12 = 2

72/(8 - 9)  Be sure and use brackets when you post a question. 8 - 9 = - 1

72/-1 = - 72

2 - 72 = - 70

Find x-intercept

The x-intercept is where the graph crosses the x-axis. To find the x-intercept, we set y1=0 and then solve for x.

3x + y = 16

3x + 1(0) = 16

x1 = 5.333 y1 = 0

Find y-intercept

The y-intercept is where the graph crosses the y-axis. To find the y-intercept, we set x2=0 and then solve for y.

3x + y = 16

3(0) + y = 16

y2 = 16 x2 = 0

Answer:

His pattern is 42cm long.

Step-by-step explanation:

Each repetition of the pattern is 8 cm (4 colors time 2cm each)

If the last color is red and he painted 6 red strips in total, then he repeated the pattern 5 times and ended on an extra red strip.

So 8cm times 5 repetitions equals 40, plus 2cm for the extra red strip.

Answer:

V≈21790.09

Step-by-step explanation:

Volume of a cylinder equals V=π*r^2*h. Find the radius by taking the base and dividing it by 2 (34/2=17). Plug numbers into equation. π·17^2·24.

The new surface area of the figure that is 1 / 3 of the original size is 198.79 ft².

The surface area of a solid is a measure of the total area occupied by the surface of an object.

Therefore, the surface area of the figure can be calculated as follows:

surface area = (5 × 6.1) + (5 × 10) + (9.8 × 6.1) + (4.9 × 6.1) + (10 × 5) + (14.8 × 4.9) +  (10 × 5) + (14.8 × 4.9) + (14.8 × 6.1) + (14.9 × 6.1)

surface area = 30.5 + 50 + 59.78 + 29.89 + 50 + 72.52 + 50 + 72.52 + 90.28 + 90.89

original surface area = 596.38 ft²

Therefore,

New surface area = 1  / 3 × 596.38

New surface area = 198.793333333

New surface area = 198.79 ft²

Answer:

36 5/6 liters

Step-by-step explanation:

There was a whole lot of math put into it that I don't wanna type, but long story short, I had to combine 12 1/5, 9 19/20, and 14 47/60. Up above is the final answer that I got.

Given:

The given rule is

[tex]f(n)=n^3-7[/tex]

Domain of the function is the set of whole numbers greater than 0.

To find:

The first 4 terms of the sequence.

Solution:

We have,

[tex]f(n)=n^3-7[/tex]

Domain of the function is the set of whole numbers greater than 0. So, the domain for first four terms of the sequence are 1, 2, 3 and 4 respectively.

For n=1,

[tex]f(1)=(1)^3-7[/tex]

[tex]f(1)=1-7[/tex]

[tex]f(1)=-6[/tex]

For n=2,

[tex]f(2)=(2)^3-7[/tex]

[tex]f(2)=8-7[/tex]

[tex]f(2)=1[/tex]

For n=3,

[tex]f(3)=(3)^3-7[/tex]

[tex]f(3)=27-7[/tex]

[tex]f(3)=20[/tex]

For n=4,

[tex]f(4)=(4)^3-7[/tex]

[tex]f(4)=64-7[/tex]

[tex]f(4)=57[/tex]

Therefore, the first 4 terms of the sequence are -6, 1, 20, 57 respectively.

Hey there!

7/8÷6/8=?

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

7/8×8/6=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

7×8/8×6=56/48

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 56 and 48 using

GCF(56,48) = 8

56÷8/48÷8=76

The fraction

7/6

is the same as

7÷6

Convert to a mixed number using

long division for 7 ÷ 6 = 1R1, so

7/6= [tex]1 \frac{1}{6} [/tex]

Therefore:

7/8÷6/8= 1 1/6

Let's do

[tex]\\ \bf\hookrightarrow \dfrac{7}{8}\div \dfrac{6}{8}[/tex]

[tex]\\ \bf\hookrightarrow \dfrac{7}{8}\times \dfrac{8}{6}[/tex]

[tex]\\ \bf\hookrightarrow \dfrac{7}{8}\times \dfrac{4}{3}[/tex]

[tex]\\ \bf\hookrightarrow \dfrac{7}{2}\times \dfrac{1}{3}[/tex]

[tex]\\ \bf\hookrightarrow \dfrac{7}{6}[/tex]

Answer:

Length of the rectangular lot = 60 meters

Width of the rectangular lot = 30 meters

Step-by-step explanation:

Let the width of the rectangular lot be x meters.

So, Length of the same = 2x metres.

[tex]A(rectangular \:lot) = (2x)(x)[/tex]

[tex]\implies A(rectangular \:lot) = 2x^2[/tex]

When length is increasEd by 40 m and width by 6 m. Then....

New length = [tex](2x + 40) \:m[/tex]

New width =[tex](x + 6) \:m[/tex]

According to the question:

[tex](2x + 40)(x + 6) = 2(2x^2)[/tex]

[tex]\implies 2x(x + 6) + 40(x + 6) - 4x^2=0[/tex]

[tex]\implies 2x^2+12x + 40x + 240 - 4x^2=0[/tex]

[tex]\implies 2x^2- 4x^2+12x + 40x + 240 =0[/tex]

[tex]\implies -2x^2+52x + 240 =0[/tex]

[tex]\implies 2(x^2-26x - 120) =0[/tex]

[tex]\implies x^2-26x - 120=0[/tex]

[tex]\implies x^2-30x+4x - 120=0[/tex]

[tex]\implies x(x-30)+4(x - 30)=0[/tex]

[tex]\implies (x-30)(x+4)=0[/tex]

[tex]\implies x-30=0,\: x+4=0[/tex]

[tex]\implies x=30,\: x=-4[/tex]

Since, x represents the side length, so its value can't be negative.

[tex]\implies x=30[/tex]

[tex]\implies 2x=2(30)=60[/tex]

Thus,

Length of the rectangular lot = 60 meters

Width of the rectangular lot = 30 meters

Answer:

Step 1: Add 2 to both sides.

7x−2+2=−9+2

7x=−7

Step 2: Divide both sides by 7.

7x/7  =  -7/7

Answer:  x=−1

Answer:

x=-1

Step-by-step explanation:

7x-2=-9 (Given)

7x=-7 (Add 2 on both sides to eliminate he -2 on the left side)

x=-1 (Divide both sides with 7 to eliminate the 7 in 7x)

Answer: x=-1
