Answer:

The correct option is 1.

Step-by-step explanation:

Formula for Consumer Price Index (CPI):

$CPI=\frac{\text{Cost of market basket in current year}}{\text{Cost of market basket in base year}}\times 100$

It is given that Consumer Price Index (CPI) for 1989 was 124.

$\text{Rate of inflation}=\frac{CPI_x-CPI_0}{CPI_0}$

Where, $CPI_x$ is current consumer price index and $CPI_0$ is initial consumer price index.

The initial consumer price index is always 100.

$\frac{124-100}{100}=0.24=24\%$

Since If the rate of inflation between the base period and 1989 is 24%, therefore option 1 is correct.

What is the measure of WUX in Circle V ?

Alja [10]

Answer:

$arc\ WUX=120^o$

Step-by-step explanation:

<u><em>The complete question is:</em></u>

In circle V, angle WXZ measures 30°. Line segments WV, XV, ZV, and YV are radii of circle V. Circle V is shown. Line segments W V, X V, Z V, and Y V are radii. Lines are drawn from point W to point X and from point Z to point Y to form secants. Point U is on the circle between points W and X. What is the measure of Arc W U X in circle V?

The picture of the question in the attached figure

step 1

Find the measure of angle XWV

we know that

The triangle VWX is an isosceles triangle, because has two equal sides (VX=VW)

we have

$m\angle WXZ=30^o\\m\angle WXV=m\angle WXZ$

so

$m\angle WXV=30^o$

Remember that an isosceles triangle has two equal interior angles

so

step 2

Find the measure of angle WVX

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

so

$m\angle\ WVX+m\angle XWV+m\angle WXV=180^o$

substitute the given values

$m\angle WVX+30^o+30^o=180^o\\m\angle WVX=180^o-60^o=120^o$

step 3

Find the measure of arc WUX

we know that

$arc\ WUX=m\angle WVX$ ----> by central angle

we have

$m\angle WVX=120^o$

therefore

$arc\ WUX=120^o$

A rectangle is inscribed in a right isosceles triangle, such that two of its vertices lie on the hypotenuse, and two other on th

Rufina [12.5K]

Answer:

Part 1) The base is $25\ in$ and the height is $10\ in$

Part 2) The base is $7.5\ in$ and the height is $18.75\ in$

Step-by-step explanation:

case 1) Right isosceles triangle of the left

Let

x------> the base of the rectangle

y----> the height of the rectangle

Remember that

In a right isosceles triangle the lengths of the legs of the triangle is the same

$y+x+y=45$

$2y+x=45$ ----> equation A

$\frac{x}{y} =\frac{5}{2}$

$x=2.5y$ -----> equation B

substitute equation B in the equation A

$2y+2.5y=45$

$4.5y=45$

$y=10\ in$

Find the value of x

$x=2.5(10)=25\ in$

case 2) Right isosceles triangle of the right

Let

x------> the base of the rectangle

y----> the height of the rectangle

Remember that

In a right isosceles triangle the lengths of the legs of the triangle is the same

$y+x+y=45$

$2y+x=45$ ----> equation A

$\frac{y}{x} =\frac{5}{2}$

$y=2.5x$ -----> equation B

substitute equation B in the equation A

$2(2.5x)+x=45$

$6x=45$

$x=7.5\ in$

Find the value of y

$y=2.5(7.5)=18.75\ in$
