If a/b=p/q
than a = pb+q but the hypothesis says that a = p+b/q. So the answer to your question is FALSE. I hope that this is the answer that you were looking for and it has helped you.

The answer is -8°F. This is because it DROPPED 8 degrees, meaning it was 8°F MINUS 8°F which would equal 0°F. Hope that helps!

Richard’s store sells pineapples and grapefruits. Pineapples originally cost $5.15 apiece, and grapefruits originally cost $2.25

sveta [45]

Answer:

c. The price of grapefruits experienced a reduction 6.01 percentage points greater than the price of pineapples.

Step-by-step explanation:

The original price of Pineapples=$5.15

New price of Pineapples=$3.88

Find change in price of Pineapples

Change in price=original price- new price

$=5.15-3.88=1.27$

The price of Pineapple was reduced by $1.27

% reduction in price

(reduction value/original value) × 100

$=\frac{1.27}{5.15} *100=24.66$

=24.66%

The original price of grape fruits=$2.25

New price of grape fruits=$1.56

Change in price of grape fruit

Change in price= original price -new price

$=2.25-1.56=0.69$

% reduction in price of grape fruits

(reduction value/original value)×100

$=\frac{0.69}{2.25} *100=30.67$

=30.67%

Answers

The fruit that has its price reduced by a greater percentage is grape fruit

How many percentage points greater = 30.67%-24.66% = 6.01 points

Two cars start together in the same direction from the same place. The first goes with a uniform speed of 10 km/h. The second go

Inga [223]

Let the second car meets the first car after n hours.

Second car starts with 8km/h, After succeeding hours his speed increases by 0.5 km.

So, Distance travelled by second car = 8 + 8.5 + 9

..... 8+(n-1) 0.5.....(1)

eqn. (1) sum of n terms Of A.P with first term 8

and common difference 0.5.

Sum of all the terms in equation 1 is also equals to the distance travelled by the first car for n hours, i.e. 10n km .

Now, we have (n/2) {16+(n-1) 0.5} = 10n........(2)

From equation (2) we get, n= 9

Hence, Both the cars will meet after 9 hours.

Hope it helps!

What is the answer to this question?

shepuryov [24]

Answer:

6.4

Step-by-step explanation:

The given triangle is a Right Angled Triangle with right angle at E.

So, measure of angle E = 90 degrees

measure of angle D = 62 degrees

measure of side FE = 12

We have to find the measure of side DE. Note that side DE is adjacent to Angle D and side FE is opposite to angle D. So we can use tangent ratio to find the measure of DE.

$\textrm{Tangent of angle}=\frac{Opposite}{Adjacent}\\\\tangent(62)=\frac{FE}{DE}\\\\tangent(62)=\frac{12}{DE}\\\\DE=\frac{12}{tangent(62)}\\\\DE=6.4$

Therefore, the value of DE, rounded to nearest tenth is 6.4
