First, you have to find x
KG and HK are equal
3x=x+8
Solve, and you get 4=x
plug that in to x+3
JL=7
LG is twice as long as JL
7*2=14
JL is 14

Given that x : 3 : 9/2 = 15/4 : 4 1/2 : y, find the value of x and y.
Lunna [17]

Answer:

x = \frac{5}{2} , y = \frac{27}{4}

Step-by-step explanation:

Equate the first 2 parts of the ratios on both sides of the equation and solve for x.

Expressing the ratios in fractional form, then

\frac{x}{3} = \frac{\frac{15}{4} }{\frac{9}{2} } = \frac{15}{4} × \frac{2}{9} = \frac{5}{6} ( cross- multiply )

6x = 15 ( divide both sides by 6 )

x = \frac{15}{6} = \frac{5}{2}

-----------------------------------------------------------------------------------

Equate the last 2 parts of the ratios on both sides and solve for y

\frac{\frac{9}{2} }{y} = \frac{3}{\frac{9}{2} } = 3 × \frac{2}{9} = \frac{2}{3} ( cross- multiply )

2y = \frac{9}{2} × 3 = \frac{27}{2} ( divide both sides by 2 )

y = \frac{27}{4}

Select all the shapes below that have a constant cross-section between a
meriva

The shapes below that have a constant cross-section between a pair of faces are cylinder, cube, sphere, hexagonal, and prism.

<h3>What is the definition of geometry?</h3>

It is concerned with the geometry, region, and density of various 2D and 3D shapes.

A cylinder is a closed solid with two parallel circular bases and a curving surface connecting them.

The shapes have a constant cross-section between a pair of faces like a cylinder.

Hence,cylinder, cube, sphere, hexagonal, and prism are the forms below that have a constant cross-section between a pair of faces.

Please help me with this problem please

9514 1404 393

Answer:

  • shortest: 11 1/8 in
  • longest: 11 3/8 in

Step-by-step explanation:

It should be no surprise that the shortest allowable length is the nominal length less the full allowed tolerance:

  11 1/4 - 1/8 = 11 1/8 . . . inches

__

Likewise, the longest allowable length is the nominal length plus the maximum tolerance:

  11 1/4 + 1/8 = 11 3/8 . . . inches

_____

Of course, you know that 1/4 = 2/8, so adding or subtracting 1/8 gives the fractions shown above.
