cos(45°) = [tex]\frac{y}{20\sqrt{2}}[/tex]

Y= 20

Z:

sin(∠BAC) = [tex]\frac{BC}{AB}[/tex]

sin(45°) = [tex]\frac{z}{20\sqrt{2}}[/tex]

The number of basket Kathy will make out of 60 tries is 23 basket.

She keeps track of the number of basket she makes while practicing her free throw shots.  

She makes 7 baskets out of 18 tries.

This is when quantities have the same ratios. Therefore,

18 tries = 7 baskets

60 tries = ?

cross multiply

number of basket = 60 × 7 / 18

number of basket = 420 / 18

number of basket = 23.3333333333

number of basket = 23 basket.

Answer:

2/3

Step-by-step explanation:

2/3 = 4/6

Is 4/6 bigger than 3/6?

Yes.

2/3 is bigger than 3/6.

And also, if you convert 2 of the fractinos to decimals, 2/3 will be approximately 0.67 and 3/6 will be 0.5.

Is 0.67 bigger than 0.5?

Yes.

2/3 is greater than 3/6

The numbers are given as:

3/6 and 2/3

Express both numbers as decimals to two decimal places

0.50 and 0.67

By comparison, we have:

0.67 is greater than 0.50

Topic : Linear equations in two variables.

Given :

Solution :

Now,

(i) + (ii)

[tex] \qquad \sf \: { \dashrightarrow 3x + 2y + (x - 2y) = - 4 + 4}[/tex]

[tex] \qquad \sf \: { \dashrightarrow 3x + 2y + x - 2y = 0}[/tex]

[tex] \qquad \sf \: { \dashrightarrow 3x \: \cancel{ + 2y} + x \: \cancel{- 2y} = - 4 + 4}[/tex]

[tex] \qquad \sf \: { \dashrightarrow 4x = 0}[/tex]

[tex] \qquad \bf \: { \dashrightarrow x = 0}[/tex]

Now, substituting the value of x in Eq (i) :

[tex]\qquad \sf \: { \dashrightarrow 3x + 2y = -4}[/tex]

[tex]\qquad \sf \: { \dashrightarrow 3(0) + 2y = -4}[/tex]

[tex]\qquad \sf \: { \dashrightarrow 0 + 2y = -4}[/tex]

[tex]\qquad \sf \: { \dashrightarrow 2y = -4}[/tex]

[tex]\qquad \sf \: { \dashrightarrow y = \dfrac{ - 4}{2} }[/tex]

[tex]\qquad \bf \: { \dashrightarrow y = -2}[/tex]

Therefore, The value of x = 0 and y = -2

The solution to the two given simultaneous equations are; x = 0 and y = -2

We are given the simultaneous equations;

3x + 2y = -4   -----(eq 1)

x - 2y = 4      ------(eq 2)

Add eq1 and eq2 to get;

4x = 0

x = 0/4

x = 0

Substitute 0 for x in eq 2 to get;

0 - 2y = 4

-2y = 4

y = -4/2

y = -2

Step-by-step explanation:

Make the denominators of both fractions the same by mulitplying the numerator (top number) and denominator (bottom number) of the fraction 3/4 by 2:

(3 x 2) / (4 x 2) = 6/8

Now compare 6/8 with 7/8 (the number line is divided into 8 equal parts. Shade 6 and then shade 7.  which is bigger?)

7/8 > 6/8

Ellis bought total 24 soda cans but in packs

Each pack contain 6 cans

Therefore,

Total packs bought by Ellis

[tex]\sf{ = }{\sf{\dfrac{ 24}{6}}}[/tex]

[tex]\sf{ = 4 \: packs }[/tex]

Ellis bought 4 packs of soda cans

So,

Total cost paid by the Ellis

[tex]\sf{ = 4 {\times}{\pounds} 1.80 }[/tex]

[tex]\sf{ = {\pounds}7.20 }[/tex]

Thus, The total cost paid by Ellis is £7.2

Connor also bought 24 cans of soda but in packs

Each pack contain 8 soda cans

Total packs bought by Connor

[tex]\sf{ = }{\sf{\dfrac{ 24}{8}}}[/tex]

[tex]\sf{ = 3 \: packs }[/tex]

Connor bought 3 packs of soda cans

So,

Total cost paid by the Connor

[tex]\sf{ = 3 {\times}{\pounds}2.10 }[/tex]

[tex]\sf{ = {\pounds}6.30 }[/tex]

Thus, The total cost paid by connor is £6.30

From Above we can conclude that,

That is,

Ellis had to pay more than connor by

[tex]\sf{ = 7.20 - 6.30 }[/tex]

[tex]\sf{ = {\pounds}0.90}[/tex]

Hence, Ellis paid more than connor by £0.90.

Triangular prism has 4 sides, including the base. The lateral area of the considered triangular prism is given by option B: [tex]12x^2 \: \rm inch^2[/tex]

Lateral area of the considered triangular prism is the sum of areas of the triangles it is made up from except that of the base triangle.

The lateral area of a right prism which is regular (all lateral sides congruent) is given by:

[tex]A_L = P \times h[/tex]

where, P = Perimeter of the base

h = height of that prism

For the given case, we have the base of the triangular prism of side length x units.

Thus, perimeter of the base = x + x + x = 3x

Height of the base = h = 4 times x = 4x

Thus, we get:

Lateral area of the prism = [tex]3x \times 4x = 12x^2 \: \rm inch^2[/tex]

Thus, The lateral area of the considered triangular prism is given by option B: [tex]12x^2 \: \rm inch^2[/tex]

The answer is :

the second one ( [tex]y=log{3} x[/tex] )

Answer:

Step-by-step explanation:

Because x=5y-4 you can substitute 5y-4 into the x in the other equation. This makes 5(5y-4) + 4y = 38. When simplified it gives 25y -20 +4y = 38. Move like terms to each side to get 29y = 58 and get y=2. Then you can substitute 2 into the y in either equation to find x. I will do x=5(2)-4 to get x=6. So x=6 and y=2

Answer:

Solution:

Simplify the distributive property and solve.

Hence, the simplified expression is 12x + 42.
