Answer:

A=1/2 Bh

6cm^2=1/2.3cm.h

12cm^2=3cmh

H=4cm

Answer:

Step-by-step explanation:

[tex](\sqrt{17}+3\sqrt{48})-(\sqrt{17}-3\sqrt{48}) =\sqrt{17}+3\sqrt{48}-\sqrt{17}+3\sqrt{48}\\[/tex]

                                                 [tex]= \sqrt{17}-\sqrt{17}+3\sqrt{48}+3\sqrt{48}\\\\= 0 + (3+3)\sqrt{48}\\\\=6\sqrt{48}\\[/tex]

Now factorize 48

[tex]= 6\sqrt{2*2*2*2*3}\\\\=6*2*2\sqrt{3}\\\\=24\sqrt{3}[/tex]

Answer:

[tex]\frac{183333333333}{100000000000}[/tex]

Step-by-step explanation:

1.83333333333 as fraction

we need to divide the fraction by the number of digits it have before decimal point to convert it to fraction

here we have 11 digits before decimal point so we need to divide it by 100000000000

so

[tex]\frac{183333333333}{100000000000}[/tex]

Y = x+1

Udbzjsjdbejdjjejejejdjejejejsjdjdjdjdjejejekieeu

Answer:

y = x + 1

Step-by-step explanation:

As x increases, y increases by 1. Therefore, the slope is 1. If we set x to 0, that'll make y equal 1. Therefore, the y-intercept is 1.

Answer:

139

Step-by-step explanation:

If x=-5

then

5*-5^2-(-5)+9

5*25+5+9

139

Answer: 139

Concept:

Here, we need to understand the idea of evaluation.  

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

Solve:

Given information

5x² - x + 9

x = -5

Substitute value into the expression

=5(-5)² - (-5) + 9

Simplify exponents

=5 (25) + 5 + 9

Simplify by multiplication

=125 + 5 +9

Simplify by addition

=[tex]\boxed {139}[/tex]

Hope this helps!! :)

74 ÷ 39.37 = 1.88m

1 meter = 39.37 inches

Answer:

Zeke will receive $2.75.

Step-by-step explanation:

Helmet cost: (3/5) x 28.75 = $17.25

Gives = $20

20 - 17.25 = 2.75

Original question:

Zeke goes to a skate shop with his friend Tristan. Tristan buys a helmet that costs $28.75. Zeke finds a helmet that is (3/5) of the cost of Tristan's helmet. If Zeke gives the cashier a $20 bill, how much change will he receive?

Answer:

Step-by-step explanation:

Refer to attached picture.

The grazing area of the goat is 3/4 of area of circle with 12 ft radius:

Tied to the corner

Means 1part among 4parts of circle or a quarter area

So grazing field

Answer:

x = 70

Step-by-step explanation:

To find the value of x we need to

we know that the figure is an isosceles triangle so the base angles will be equal

we also know that angle sum of triangle is 180

so

40 + x + x = 180

40 + 2x = 180

2x = 180 - 40

2x = 140

x = 140/2

x = 70

Answer:

-2 ≤ 2x-4 < 4

The most simplified version of it is 49/50

Answer:

98/100

Step-by-step explanation:

The number after the decimal is the tenths place. And the second number after the decimal is in the hundredths place. And so on...

So .98 would be in the hundredths place making it 98/100.

If you want to simplify it even more, you would make it 49/50.

Hope that helped : )

Answer:

X=64°

Step-by-step explanation:

Solution,

x+54°=118° because the sum of two interior angles is equal to the opposite non adjacent exterior angle.

x+54°-54°=118°-54°

x=64°

Answer:

64 degrees

The Process:

54 is already a number that's not going to change, so that's fine. 118 is an outside angle, and a flat line is 180 degrees, so to find the inside angle, you have to do 180 - 118. Once again, there are 180 degrees in a triangle to you need to add 180 - ((180 - 118) +54) and you have the value of x.

Answer:

[tex]x = - \frac{5}{22} [/tex]

Step-by-step explanation:

[tex]4 - \frac{2(x - 4)}{3} = \frac{3(2x + 5)}{2} [/tex]

➡️ [tex] 4x - \frac{2x - 8}{3} = \frac{6x + 15}{2} [/tex]

[tex] ➡️ 24 - 2(2x - 8) = 3(6x + 15)[/tex]

[tex] ➡️ 24 - 4x + 16 = 18x + 45[/tex]

[tex] ➡️ 40 - 4x = 18x + 45[/tex]

[tex] ➡️ - 4x - 18x = 45 - 40[/tex]

[tex] ➡️ - 22x = 5[/tex]

➡️ [tex] x = - \frac{5}{22} [/tex]

Answer:

3

Step-by-step explanation:

Answer:

223.05/x(11.95+7.95) 11.21.

Step-by-step explanation:

If each hat costs 11.95 plus a shipping fee of 7.95, you must add those numbers together. This makes the variable that will help indicate the number of hats ordered. Then you divide 223.05 by 19.9 (the total cost per hat) and you'll get your answer of 11.21 rounded.

Answer:

b = -30

Step-by-step explanation:

-b/5 - 27 = -21

~Add 27 to both sides

-1/5b = 6

~Multiply -5 to both sides

b = -30

Best of Luck!

Answer:

pi*z^2*a or "pizza"

Step-by-step explanation:

The dimensions given describe a cylinder, for which the basic volume formula would be base x height.

The base would be a circle, with the radius z as given while the height is a.

The formula for the area of a circle is pi * r^2, and our radius is z, so the area of a circle with radius z is pi * z^2.

Now, all we need to do is multiply by the height, a. This gives us a volume of pi* z^2 *a

Side note:

z^2 can be written as zz, so the actual area of the pizza could be represented by "pizza".
