Evaluate the numerical expression.



(5 + 3) x 2 - 6


please help!

Answer:

7

Step-by-step explanation:

When working with order of operations, use the acronym 'PEMDAS' (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)

The equation should basically be done in that order.

There are no parenthesis,

no exponents,

But there IS multiplication.

1 x 10 = 10.

So now, what is left over is 10 - 3.

There addition, but there IS subtraction.

10 - 3 = 7.

7 is what is left over.

Therefore, 1 x 10 - 3 in standard form is 7.

Answer:

Option a.

Step-by-step explanation:

Two figures are similar if they have the same shape, but maybe different sizes, so if we have a triangle, and we dilate/contract it with a scale factor K, the original triangle and the dilated/contracted one will be similar.

Two figures are congruent if they have the same shape and size. For example, transformations that do not change the size will make congruent figures, those transformations are reflections, rotations and translations.

Now we need to find a sequence of transformations that would result in the two triangles being similar but no congruent, then we need to find the sequence of transformations that has a dilation/contraction in it.

The only sequence that has a dilation is the first one:

a) Rotation 90° centered about the origin, followed by a dilation of scale factor 3 centered about the origin.

Then option a is the correct one.

Answer:

Step 3 contains error.

Step-by-step explanation:

The given equation is :

[tex]\dfrac{1}{4}(\dfrac{1}{3}k+9)=6[/tex]

Step 1.

Cross multiplying,

[tex](\dfrac{1}{3}k+9)=24[/tex]

Step 2.

Subtract 9 from both sides

[tex]\dfrac{1}{3}k+9-9=24-9\\\\\dfrac{1}{3}k=15[/tex]

Step 3.

Cross multiplying

[tex]k=15\times 3\\\\k=45[/tex]

So, there is an error in step 3. The correct answer should be 45.

Answer:

s = 47

Step-by-step explanation:

The measure of the exterior angle of a triangle is equal to the sum of the opposite interior angles

s+45 = s+6  + s-8

Combine like terms

s+45 = 2s-2

Subtract s from each side

s+45-s =2s-2-s

45 =s-2

Add 2 to each side

45+2 = s-2+2

47 =s

To look at the slope you can count over four and then up one and its at the next point.

Also, the place on the y-axis is at -2

So, b makes the most since :)

Answer:

y ≈ 6.7

Step-by-step explanation:

Using the sine ratio in the right triangle

sin26.5° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{y}{15}[/tex] ( multiply both sides by 15 )

15 × sin26.5° = y , then

y ≈ 6.7 ( to 1 dec. place )

Answer:

s = c + 15

s + c = 27

substitute for s:

(c + 15) + c = 27

2c = 12

c = 6

s = 21

The system of equation which correctly represents the situation is s + c = 27 and s - c = 15.

Linear equations involve one or more expressions including variables and constants and the highest exponent of the variable is 1.

System of linear equations involve two or more linear equations.

Given that,

Combined total of sheep and cows = 27

Number of sheep = Number of cows + 15

Let s represents the number of sheep and c represents the number of cows.

s + c = 27

s = c + 15 ⇒ s - c = 15

Hence the system of equation is s + c = 27 and s - c = 15.

Step-by-step explanation:

Negative by negative = positive

Answer:

See Below.

Step-by-step explanation:

In the given figure, O is the center of the circle. Two equal chords AB and CD intersect each other at E.

We want to prove that I) AE = CE and II) BE = DE

First, we will construct two triangles by constructing segments AD and CB. This is shown in Figure 1.

Recall that congruent chords have congruent arcs. Since chords AB ≅ CD, their respective arcs are also congruent:

[tex]\stackrel{\frown}{AB }\, \cong\, \stackrel{\frown}{CD}[/tex]

Arc AB is the sum of Arcs AD and DB:

[tex]\stackrel{\frown}{AB}=\stackrel{\frown}{AD}+\stackrel{\frown}{DB}[/tex]

Likewise, Arc CD is the sum of Arcs CB and DB. So:

[tex]\stackrel{\frown}{CD}=\stackrel{\frown}{CB}+\stackrel{\frown}{DB}[/tex]

Since Arc AB ≅ Arc CD:

[tex]\stackrel{\frown}{AD}+\stackrel{\frown}{DB}=\stackrel{\frown}{CB}+\stackrel{\frown}{DB}[/tex]

Solve:

[tex]\stackrel{\frown}{AD}\, \cong\,\stackrel{\frown}{CB}[/tex]

The converse tells us that congruent arcs have congruent chords. Thus:

[tex]AD\cong CB[/tex]

Note that both ∠ADC and ∠CBA intercept the same arc Arc AC. Therefore:

[tex]\angle ADC\cong \angle CBA[/tex]

Additionally:

[tex]\angle AED\cong \angle CEB[/tex]

Since they are vertical angles.

Thus:

[tex]\Delta AED\cong \Delta CEB[/tex]

By AAS.

Then by CPCTC:

[tex]AE\cong CE\text{ and } BE\cong DE[/tex]

Answer:

150%

Step-by-step explanation:

Purchase Cost= £12 for 10kg

Sales

1 bag= 200g

200g=1 bag

1 g= 1/200 bag

10000g or 10kg= 1/200 * 10000 = 50 Bags

1 Bag = 0.60

50 Bags= 0.60*50= £30

Profit= £30- £12= 18

% Profit= 18/12 *100

=150%

Answer:

$112 for 16 hours

$280 for 40 hours

Step-by-step explanation:

Well, given that if 7x dollars are earned working for x hours (x is assumed to be 1), then $7 are earned for every hour worked. So we can pretty much multiply $7 (Money earned per hour) by 16 and then 40 (Hours worked). 7*16=112, and 7*40=280. And there are your two answers.

Answer:

7

Step-by-step explanation:

We know that alternate angles ( Z angles) are equal

So, the angle that is adjacent to (13x + 2) = (12x+3)

First, calculate the measure of the angle adjacent to (13x+2)

We know that the angles on a straight line add up to 180 degrees.

Therefore, the angle adjacent to (13x+2) = 180-(13x+2)

Simplify this to: 178-13x

So, now we have an equation

178 - 13x = 12x + 3

Rearrange to find the value of x

25x = 175

x = 7

Step-by-step explanation:

Q9) Surface Area of a cylinder

= 2πr(r + h)

Diameter = 12cm , Radius = Diameter/2 = 12 cm/2

r = radius = 6cm

h = height = 10 cm

Surface area = 2 × π × 6(6 + 10)

= 603.18579 cm²

Approximately = 603.2 cm²

Q11) Volume of a rectangular prism

Length × Width × Height

Length = 6.5cm

Width = 8.5 cm

Height = 4 cm

Volume = 6.5 cm × 8.5 cm × 4 cm

Volume = 221 cm³

Q12) Volume of the cylinder = πr²h

r = radius = 1.7m

h = height = 9 m

Volume = π × 1.7 × 9

= 81.71 m³

Approximately = 81.7 m³

Q13) Volume of the cylinder = πr²h

Diameter = 0.8m, Radius = Diameter/2 = 0.8m/2

r = radius = 0.4m

h = height = 1.5 m

Volume = π × 0.4 × 1.5

= 0.75 m²

Approximately = 0.8 m³

Answer:

v = 120

Step-by-step explanation:

The right angle is egual to 180-39-v, so it is: v-141

U now that the sum of the internal angles of a triangle is 180°.

180 = (v-48)+(v)+(v-141)

180 = 3v - 180

3v = 360

v = 360/3

v = 120

Yes you have enough money because with the dicound the crocs are $45.50

Step-by-step explanation:

u have $50 the crocs is $65 but have 30% off

$65 with 30% off is $45.50

Answer:

YAY, you can buy the Crocs!

Step-by-step explanation:

First we divide $65/100% to find one percent.

1% = 0.65

100% (original price) - 30% (sale) = 70% --> so the Crocs cost 70% their original price.

0.65 (1%) x 70 = $45.50 (final price of Crocs)
