Answer:

(13,3)

Step-by-step explanation:

The coordinates of V' after the transformation is: (13, 3)

The coordinate of V is given as:

V = (2,1)

The dilation rule is given as: D5.

So, we have:

V' = (2 * 5, 1 * 5)

Evaluate the product

V' = (10, 5)

Also, the translation rule is given as: (3,-2)

So, we have:

V' = (10 + 3, 5 -2)

Evaluate the sums

V' = (13, 3)

Hence, the coordinates of V' after the transformation is: (13, 3)

Answer:

The orange region has an area of 324m²

Step-by-step explanation:

You can calculate this by finding the area of the smaller white rectangle, and subtracting it from the larger orange rectangle.

The smaller rectangle has the dimensions 8m × 5m, giving us 40m².

The larger rectangle is 13m × 28m, giving us the area 364m²

So the orange area is equal to 364m² minus 40m², or 324m²

Answer:

324[tex]cm^{2}[/tex]

Step-by-step explanation:

The are of the shaded region is equal to the area of the big rectangle minus the area of the small rectangle. So the are of the shaded region can be found in a follwoing way

The are of the shaded region = Area of the big rectangle - Area of the small recatngle

The are of the shaded region = 13 x 28 - 5 x 8

The are of the shaded region = 364 - 40

The are of the shaded region = 324[tex]cm^{2}[/tex]

number of hours  worked 2 = money earned $60,

so we can conclude that

the money he earned depend on the hours worked (independent variable) and that

number of hours  worked 1 = money earned $30

A. True

hours worked IS the independent variable

9 hours of work = 9*$30  = $270 IS correct

B. False

money earned IS the dependent variable

9 hours of work is NOT $540

C. False

the money earned is NOT independent

for 9 hour will NOT earn $540

D.True

the number of hours IS dependent variable

the 9 hours of work IS earning $270

Distance cover in feet in one minute and one second are 5,016 feet and 83.6 feet

Given that;

Speed of car travelling = 57 mph

Find:

Distance cover in feet in one minute

Distance cover in feet in one second

Computation:

Speed of car travelling = 57 mph

Speed of car travelling in feet = 57 × 5280

Speed of car travelling in feet = 300,960 feet per hour

Distance cover in feet in one minute = 1 × [300,960 / 60]

Distance cover in feet in one minute = 5,016 feet

Distance cover in feet in one second = 1 × [5016 / 60]

Distance cover in feet in one second = 83.6 feet

Answer:

45

Step-by-step explanation:

Angles in a triangle add up to 180 and a right angle (indicated by the square) is 90. So, 180-90=90. The lengths are parallel which means the remaining angles must equal the same. 90/2=45

Answer:

$169.69

Step-by-step explanation:

for this equation disregard the first # (48)

add all of the amount of square feet from the bathrooms (30.5 + 30.5 + 40.5) which gets you 71

multiply 71 x 2.39 = 169.69

your answer is therefore $169.69

Answer:

t = -11

Step-by-step explanation:

Solve for t:

-3 t - 8 = 25

Add 8 to both sides:

(8 - 8) - 3 t = 8 + 25

8 - 8 = 0:

-3 t = 25 + 8

25 + 8 = 33:

-3 t = 33

Divide both sides of -3 t = 33 by -3:

(-3 t)/(-3) = 33/(-3)

(-3)/(-3) = 1:

t = 33/(-3)

The gcd of 33 and -3 is 3, so 33/(-3) = (3×11)/(3 (-1)) = 3/3×11/(-1) = 11/(-1):

t = 11/(-1)

Multiply numerator and denominator of 11/(-1) by -1:

Answer:  t = -11

[tex] - 3t + ( - 8) = 25[/tex]

[tex] - 3t - 8 = 25[/tex]

[tex] - 3t = 25 + 8 \\ - 3t = 33 \\ t = \frac{33}{ - 3} \longrightarrow \frac{ \cancel{33}}{ \cancel{ - 3} } = \frac{11}{ - 1} \\ t = - 11[/tex]

[tex] - 3( - 11) + ( - 8) = 25 [/tex]

Distributing or multiplying both negative, we would get positive.

[tex]33 - 8 = 25 \\ 25 = 25 \: \: \purple{ \checkmark}[/tex]

The equation is true for t = -11. Hence the answer is t = -11.

Answer:

y=4*10-1

y=39

you just need to replace the x with 10

The value of y, when x=10 is 39.

The given equation is y = 4x - 1.

We need to find the value of an equation for x=10.

Solving equations is computing the value of the unknown variable still balancing the equation on both sides. An equation is a condition on a variable such that two expressions in the variable have equal value. The value of the variable for which the equation is satisfied is said to be the solution of the equation.

Now, put x=10 in the given equation and simplify.

That is, y=4×10-1

⇒y=39

Therefore, the value of y, when x=10 is 39.
