Answer:

h = 5.4

Step-by-step explanation:

Basically these are 2 similar triangles. That means:

Corresponding sides are proportional.

We can set up a ratio of each triangle separately and equate, cross multiply and solve for "h".

h corresponds to 2.4

2.9 corresponds to 1.3

Setting up the ratio and solving for h:

$\frac{h}{2.4}=\frac{2.9}{1.3}\\1.3h=2.4*2.9\\1.3h=6.96\\h=\frac{6.96}{1.3}\\h=5.35$

Rounded to 1 decimal place,

h = 5.4

Answer:

Firstly, from the diagram we are given that the length of XB is congruent to BZ, and YC is congruent to CZ. Based on this information, we know that B is the midpoint of XZ, and C is the midpoint of YZ. This means that BC connects the midpoints of segments XZ and YZ. Now that we know this, we can use the Triangle Midsegment Theorem to calculate the length of BC. This theorem states that if a segment connects the midpoints of two sides of a triangle, then the segment is equal to one-half the length of the third side. In this scenario, the third side would be XY, which has a length of 12 units. Therefore, the length of BC = 1/2(XY), and we can substitute the value of XY and solve this equation:

BC = 1/2(XY)

BC = 1/2(12)

BC = 6

Randy bought a zero coupon bond and a TIPS 5 years ago for $2,500 each. Both had 10 years to maturity. The TIPS's coupon was 2%

iren2701 [21]

Zero coupon bonds do not earn interest. It is usually sold at a big discount and its redeemable value if beyond its face value will only be redeemed once it reaches maturity.

TIPS stands for Treasury Inflation Protected Securities.

TIPS:
2,500 x 2% x 5 years = 250
2,500 + 250 = 2,750

Zero coupon bond after 5 years: 2,500

Maximum real value of his bonds if he sells them today.

2,750 + 2,500 = 5,250

Mattison's favorite clothing store is having a sale.Jeans are 25% off mattison bought 2 pairs of jeans that were originally pric

Mamont248 [21]

Answer:

Mattison paid 54 after the discounts for 2 jeans.

Step-by-step explanation:

Original price of the jeans = 35.99

Discount on the jeans = 25%

So, discounted amount on each jeans = $\frac{25}{100} \time 35.99 = 8.99$

So, the actual amount paid for 1 jeans = Actual Price - Discounted amount

= 35.99 - 8.99 = 27

So, the price paid for 2 jeans = 27 x 2 = 54

Hence, Mattison paid 54 after the discounts for 2 jeans.

According to a survey conducted by an environmental organization, the probability that an eligible voter cares strongly about en

Alina [70]

Answer:

The probability that the person cares strongly about environmental issues but does not vote regularly is P=0.33.

Step-by-step explanation:

We have:

Probability that the voter cares for the environment P(E)=0.63

Probability that the voter votes regularly P(R)=0.51

Probability that the voter votes regularly and cares for the environment P(R,E)=0.30

We have to calculate the probability that the voter cares for the environment but does not vote regularly P(not R, E).

We know that the probability that the voter cares for the environment is 0.63, and is divided between the ones that vote regularly and the ones that don't:

P(E)=P(R,E)+P(not R,E)=0.63

We also know that the probability that the voter votes regularly and cares for the environment is P(R,E)=0.30. Then:

P(E)=0.30+P(not R,E)=0.63

P(not R,E)=0.63-0.30=0.33

The probability that the person cares strongly about environmental issues but does not vote regularly is P=0.33.
