Answer:

72 mph

Step-by-step explanation:

Please give brainliest

You have distance =210 miles

Increase it by 20%

210+(210*0.2) = 252 miles I wrote 0.2 instead of writing 20%/100% hope you understand.

The new route is 252 miles

Time travelled = 3.5 hours

Speed=distance/time

Speed = 252/3.5 = 72 mph

the fireplace would have 24 bricks on the 10th row

Answer:

27 bricks

Step-by-step explanation:

y= 54- 3(x-1)

y= 57- 3x

is the function, y= number of bricks on the xth row, x= row number above the bottom one

x=10 ⇒ y= 57 - 3*10 ⇒ y= 27 bricks

Answer: it would be 1.25 since 1/4 is a fraction

1st 1/4 x 5/1

2nd 1+4 =5  keep the denominator

so the final product would be 5/4 or 1.25

Solution of expression 1/4 × 5 is 1.25

Division is an operation that represents the basic idea of repeated subtraction of the same number. It is inverse of multiplication operation.

Given expression

1/4 × 5

= 5/4

= 1.25

Hence, 1.25 is solution of given expression.

x x y = (13 i + 4 j - 9 k) x (- i + 7 j - 4 k)

Distribute the cross product:

x x y = 13*(-1) (i x i) + 4*(-1) (j x i) + (-9)*(-1) (k x i)

........... + 13*7 (i x j) + 4*7 (j x j) + (-9)*7 (k x j)

........... + 13*(-4) (i x k) + 4*(-4) (j x k) + (-9)*(-4) (k x k)

x x y = -13 (i x i) - 4 (j x i) + 9 (k x i)

........... + 91 (i x j) + 28 (j x j) - 63 (k x j)

........... - 52 (i x k) - 16 (j x k) + 36 (k x k)

By definition of the cross product, we have

i x i = j x j = k x k = 0

i x j = k

j x k = i

k x i = j

and for any two vectors x and y, the product is anti-symmetric:

x x y = -(y x x)

This makes the products on the "diagonal" vanish, and we can condense terms using the anti-symmetry property:

x x y = (4 + 91) (i x j) + (9 + 52) (k x i) + (63 - 16) (j x k)

x x y = 95 k + 61 j + 47 i

x x y = 47 i + 61 j + 95 k

Answer: Subtituting CD =5 in AB + CD = JK

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

• AB + CD = JK (equation 1 )

• CD = 5 (equation 2)

So, we simply have to combine the equations.

Substituting CD =5 in equation 1:

AB + CD = JK

AB+(5) =JK

Answer:

(12,-2), (10,-1), (8,0), (6,1) and (4,2).

Step-by-step explanation:

If a function is defined as

[tex]f(x)=\{(x,y):x\in R,y\in R\}[/tex]

then its inverse is defined as

[tex]f^{-1}(x)=\{(y,x):x\in R,y\in R\}[/tex]

It means coordinates of ordered pairs are interchanged.

From the given table it is clear that the function passing through the points (-2,12), (-1,10), (0,8), (1,6) and (2,4).

Using the above definition, we can say that the inverse function passing through the points (12,-2), (10,-1), (8,0), (6,1) and (4,2).

Therefore, the required ordered pairs are (12,-2), (10,-1), (8,0), (6,1) and (4,2).

Step-by-step explanation:

complementary angles are angles that  added equal to an angle of 90 degrees and it says they are not congruent so the two angles are diferent

the given statement "Two complementary angles are not congruent" is not true. The counter-example is 45°+45°=90°.

The given statement is "Two complementary angles are not congruent."

Two angles are Complementary when they add up to 90°.

Now, if we add 45°+45°=90°

Therefore, the given statement "Two complementary angles are not congruent" is not true. The counter-example is 45°+45°=90°.

Answer:

1.

30/100×450

0.3×450

135

450-135=315

So the sale price of a shirt is Nu.315

2.

30/100×450

0.3×450

135

450+135=585

So the selling price of the shirt is Nu.585

Answer:

Q1:315

Q2:585

Step-by-step explanation:

450 -30% (Percentage decrease) =

450 - (30% × 450) =

450 - 30% × 450 =

70 ÷ 100 × 450 =

70 × 450 ÷ 100 =315

Q2: 450 + 30(Percentage increase) =

450 + (30% × 450) =

450 + 30% × 450 =

130 ÷ 100 × 450 =

[tex]2x - 3y = 12[/tex]

[tex]-4(2x - 3y) = -4(12)[/tex]

Step-by-step explanation:

Given

[tex]y = \frac{2}{3}x - 4[/tex]

Required

Equivalents of the given equation;

We start by multiply both sides of the equation by 3

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

[tex]3y = 3 * \frac{2}{3}x - 3 * 4[/tex]

[tex]3y = 2x - 12[/tex] ---- Equation 1

Subtract 3y from both sides

[tex]-3y + 3y = 2x - 12 - 3y[/tex]

[tex]0 = 2x - 12 - 3y[/tex]

Add 12 to both sides

[tex]12 + 0 = 2x - 12 - 3y + 12[/tex]

[tex]12 = 2x - 3y[/tex]

Rearrange:

[tex]2x - 3y = 12[/tex] ---- This is equivalent to the given equation;

Multiply both sides of the above equation by -4

[tex]2x - 3y = 12[/tex]

[tex]-4(2x - 3y) = -4(12)[/tex]  ---- This is also equivalent to the given equation;

From the list of given options, only these two are equivalent to [tex]y = \frac{2}{3}x - 4[/tex]
