HEEEELLLLLPPPPPPPPP!!!!!!!!!

Answer:

D, 6 x 3 x 3

Step-by-step explanation:

One area of a square is 3 x 3 there are 6 squares so we multiply by 6 too.

Answer:

75

Step-by-step explanation:

64.4-16.1=48.3

48.3 divided by 64.4= 0.75

0.75x100=75

===================================================

Explanations:

Problem 1

We have B = 62+32 = 94 people who wear a belt. Of this total, A = 62 belt wearers also have a watch. So A/B = 62/94 = 0.6596 = 65.96% = 66% of the belt wearers have a watch. This value is approximate.

-------------------------------

Problem 2

In the previous problem we found that roughly 66% of the belt wearers have a watch. This must mean about 100% - 66% = 34% of the belt wearers do not have a watch.

-------------------------------

Problem 3

The question is "Among left handers, what proportion has neat handwriting?" which means we're effectively only concerned with the first row that says "left-handed". In this row, there are 5 who write neat, and 10 who do not. We have B = 5+10 = 15 people who are left-handed. We'll divide everything in this row by this value of B.

So for A = 5, it turns into the approximate proportion A/B = 5/15 = 0.33 meaning that about 33% of the left-handers have neat handwriting.

For the other value in this row, A = 10 turns into A/B = 10/15 = 0.67 = meaning that about 67% of the left-handers have messy hand writing.

You'll do the same thing for row 2, but you'll divide everything by B = 65 (because there are 34+31 = 65 right-handed people total).

The filled out table is shown below.

-------------------------------

Problem 4

Let's say we ignore the percentage signs. Adding the values across the first row gets us B = 86+14 = 100 people who passed the quiz. Of that, A = 86 people who passed also studied as shown in the top left corner.

We can then see that A/B = 86/100 = 86% of the people who passed the quiz also studied. Notice the phrasing here. It's not the other way around. We would not say "86% of the people who studied passed the quiz". Your teacher has the order swapped unfortunately. If choice C said "86% of the people who passed the quiz studied for the test", then it would be fully correct. However, I think that's what they were going for and made a typo.

If we did state that "86% of the people who studied passed the quiz", then we'd be considering the first column instead of the first row. However, note how the percentages in the first column do not add to 100%.

Answer:

4 / 3

Step-by-step explanation:

tan x = opposite / adjacent

tan x = AB / AC

tan x = 4 / 3

{ x = theta ]

9514 1404 393

Answer:

  tan(θ) = 4/3

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

  Tan = Opposite/Adjacent

Then ...

  tan(θ) = AB/AC

  tan(θ) = 4/3

Answer:

Doesn't fit

Step-by-step explanation:

There are 2.4litres in the beaker if you count the lines; they increment by 0.4 litres each. The volume of the storage container is 20 x 15 x 7 = 2100 cm^3 (cm cubed). 1 cm^3 = 1 ml; the cube can hold 2100 mL which is 2.1 litres, which is less than the 2.4 litres in the beaker, therefore it will not fit.

This beaker will not fit into this rectangular food storage container.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Since,  There are 2.4litres in the beaker, they increment by 0.4 liters each.

Hence, The volume of the storage container is,

⇒ 20 x 15 x 7

⇒ 2100 cm³

Since, Here we have;

1 cm³ = 1 ml

So, The cube hold 2100 mL which is 2.1 liters,

Clearly, It is less than 2.4 liters in the beaker.

Thus, This beaker will not fit into this rectangular food storage container.

#SPJ3

Answer:

x=13° & y=74°

Step-by-step explanation:

y=74°(cointerior angle r equal)

now,

y=4x+22(vertically opposite angles equal)

Answer:

x = 21

Step-by-step explanation:

The 74 angle and y angle are supplementary which means they add up to 180 degrees, so 180 - 74 = 106

Then you know that y is equal to 4x + 22

so then you just set 4x + 22 equal to 106

then you subtract 22 from both sides which leaves you the equation 4x = 84

then you divide 84/4 which equals 21

Answer:

82.236

Answer:

D. 174 m^2

Step-by-step explanation:

the formula for area for squares is l*w so 12*12= 144

then for the triangle the formula is l*w/2

so 12*5=60/2=30

144+30=174

6-3=3 then power of 2 which is 9 then plus 1

Answer:

C

Step-by-step explanation:

Substitute 6 for "x" in (x - 3)² + 1

(6 - 3)² + 1

We now evaluate the expression using PEMDAS

Parenthesis

Exponents

Multiplication and division ( from left to right )

Addition and subtraction ( from left to right )

Step 1: parenthesis

6 - 3 = 3

We would then have (3)² + 1

step 2: exponents

3²=9

we would then have 9 + 1 which = 10

Hence, the answer is C

Given:

In triangle ABC, AE is the angle bisector.

[tex]AB=4, BE=2, AC=x, CE=3[/tex]

To find:

The value of x.

Solution:

According to the angle bisector theorem, the angle bisector of a triangle divides the opposite side of the triangle into two parts. These two parts are proportional to the other two sides of the triangle.

Using the angle bisector theorem, we get

[tex]\dfrac{AB}{AC}=\dfrac{BE}{CE}[/tex]

[tex]\dfrac{4}{x}=\dfrac{2}{3}[/tex]

On cross multiplication, we get

[tex]4\times 3=2\times x[/tex]

[tex]12=2x[/tex]

Divide both sides by 2.

[tex]\dfrac{12}{2}=x[/tex]

[tex]6=x[/tex]

Therefore, the value of x is 6.

Answer:

t = 0.0475p

Step-by-step explanation:

If

p = paycheck ; t = amount paid in state income tax

Amount contributed towards retirement :

5% of p ; 0.05p

Amount left :

Paycheck - contribution

p - 0.05p = 0.95p

Amount paid in state income tax :

5% of amount left

5% of 0.95p

5/100 * 0.95p

0.05 * 0.95p

= 0.0475p

Hence, state income tax, t = 0.0475p
