Answer:

y = -12

Step-by-step explanation:

-7/3y - 2/9 = 1/3

cross multiple for 1/3:

-21/3y - 6/9 = 1

cross multiply for 3y and 9:

-21 - 6 = 3y + 9

3y + 9 = -27

3y = -36

y = -12

Answer:

m<B = 141 degrees

Step-by-step explanation:

This shape is a heptagon meaning its angles should have a sum of 900 degrees.

we are given the degrees and we need to ad them up

148+90+120+129+130+142=749

then we subtract 749 from 900 which looks like

900-749=141

from subtracting 749 from 900 we get 141 hence we get our answer that m<B = 141 degrees

Step-by-step explanation:

The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle. Basically, it is equal to half of the base times height, i.e. A = 1/2 × b × h.

Answer:

54 units²

Step-by-step explanation:

Formula we use,

→ Area = ½ × b × h

Now the area of the triangle is,

→ ½ × b × h

→ ½ × 18 × 6

→ 9 × 6

→ 54 units²

Hence, the area is 54 units².

Answer:

base = 3

Step-by-step explanation:

The area of triangle is calculated using the following formula:

1/2*b*h (b: base, h: height)

The area and height is given, to find the base we can make the following equation:

1/2*b*9 = 54

9b/2 = 54 multiply both sides by 2

9b = 27 divide both sides by 9

b = 3

Answer:

Total Surface Area = 1008 cm^2

Step-by-step explanation:

2 X 1/2 X (12 X 9) (Surface area of the two triangles) (Area of triangle = 1/2 Base X Height)

+ 25 X 15 (Slanted Surface)

+ 25 X 9 (Back Rectangle)

+ 25 X 12 (Bottom Rectangle)

= 1008

The use of estimates to make the decisions It is important to calculate those estimates to at least six decimal places.

We have given the options that are

A. It is important to always use a 95% confidence level

B. It is important to remember that you will never achieve certainty

C. It is important to calculate those estimates to at least six decimal places.

D. It is important to use a 100% confidence level so as to achieve certainty.

E. All of the above

F. None of the above

We have to determine the correct decision.

Any of numerous procedures used to calculate the value of some property of a population from observations of a sample drawn.

That is we are estimating the value up to 6 decimal places

Therefore option C is correct.

Step-by-step explanation:

Given:

[tex]\displaystyle \large{3x-1\geq 11}[/tex]

Answer:

[tex]\Large \boxed{\sf 20\%}[/tex]

Step-by-step explanation:

→ We want to calculate the percentage increase we saw in our premium.

→ To calculate the percentage increase we saw in our premium, let's calculate the difference between our first six-month car insurance premium and our renewal premium:

[tex]\sf 786.25 - 629.00 = 157.25[/tex]

→ Calculate the percentage:

→ The formula used to calculate the percentage is:

[tex]\sf \dfrac{value}{total ~value} \times 100\%[/tex]

→ Apply this formula with value = 157.25 and total value = 786.25:

[tex]\sf \dfrac{157.25}{786.25} \times100\%[/tex]

→ Simplify the expression:

[tex]\sf \dfrac{157.25}{786.25} \times100\%\\\\\\= 0.2 \times100\%\\\\\\= 0.2 \times \dfrac{100}{100} \\\\\\= 0.2 \times 1\\\\\\= 0.2\\\\\\= \dfrac{20}{100} \\\\\\\boxed{\sf= 20\%}[/tex]

So the percentage increase we saw in our premium is 20%.

Answer:

Cost of Computer: $734

Cost of Printer: $367

Step-by-step explanation:

These two equations can represent the costs; x = price of computer; y = price of printer.

x + y = 1101

2y = x

If you graph these, you get an intersection point of (734, 367). This means that the only place that both equations are fulfilled is on (734, 367).

Then you can check your work:

734+367=1101

367*2=734

Step-by-step explanation:

h varies directly with a and inversely with b.
