Answer:

The answer is: 1.99<h<2.37

Step-by-step explanation:

The procedure is as followed

V=πr^2h

225=π(5.5)^2h

h=2.37

225=π(6)^2h

h=1.99

Find the value of the sec 19° using your calculator.A. 0.989
B. 0.946
C. 1.058
D. 1.011

Answers

secant is the inverse of cosine. In this case, using a calculator cosine of 19 degrees in degrees mode, is equal to 0.9455. The reciprocal of this number is the answer to the expression secant 19 equal to 1.058. answer then is equal to C.

What will be the perimeter and the area of the rectangle below if it is enlarged using a scale factor of 7.5?A rectangle is shown. The length of the rectangle is labeled as 8 cm, and the width is labeled as 6 cm.

Perimeter = 58 cm, area = 209.25 cm2

Perimeter = 58 cm, area = 2,700 cm2

Perimeter = 210 cm, area = 2,700 cm2

Perimeter = 210 cm, area = 209.25 cm2

Answers

Answer with Step-by-step explanation:

The perimeter(P) and area(A) of a rectangle is given by:

P=2(l+w)

A=lw

Where l is the length and w is is the width of the rectangle

original length and width

l=8 cm

w=6 cm

New length and width

l'=8×7.5=60 cm

w'=6×7.5=45 cm

P=2(60+45)

=210 cm

Area=60×45

=2700 cm²

Hence, Correct option is:

Perimeter = 210 cm, Area = 2,700 cm²

enlarged by a scale factor of x means times each dimention by x

P=2(L+W)
A=LW

original L and W
L=8cm
W=6cm

new
nL=8*7.5=60cm
nW=6*7.5=45cm

newP=2(60+45)=2(105)=210cm
newA=(60)(45)=2700cm^2

3rd from top is answer

Y=3x 2x+y=15
Can you please help with this? It's confusing. It's soling systems of equations by substitution

Answers

so you subtitute y=3x into
2x+y=15
so
2x+(3x)=15
add like terms
5x=15
divide both sides by 5
x=3

subtitute x=3 into first equation (y=3x)
y=3(3)
y=9

it's simple jus plug in 3x into Y and u will have 2x+3x=15
5x=15
the answer(x=3)

Angle x is the largest angle in triangle xyz. Angle y is the smallest angle. How does the sum of the measures of angles y and z compare to the measure of angle x

Answers

Knowing that the angles of the triangle has a total of 180 degrees, so we can have the following:

x + y + z = 180
y + z = 180 - x
or
x = 180 - y - z

In this approach, we can't give the actual values since there are no values presented.
