What is the measure of the missing angle?

1 answer:

3 0

The three angles of a triangle should equal 180 so add 52+34 which equals 86.Then subtract 86 from 180 to get the third angles measure which is 94 so the answer is 94.

The product has decreased by 80 %

Solution:

The product of the original numbers: xy

One number is decreased by 75 %

Let x be the number decreased by 75 %

new number = x - 75 % of x

$new\ number = x - 75 \% \times x\\\\new\ number = x(1-75 \%)\\\\new\ number = x(1-\frac{75}{100}) = x(1-0.75) = 0.25x$

Another number is decreased by 20 %

Let y be the number decreased by 20 %

new number = y - 20 % of y

$new\ number = y - 20 \% y\\\\new\ number = y(1-20 \%)\\\\new\ number = y(1-\frac{20}{100}) = y(1-0.2) = 0.8y$

Now the product is given as:

$product = 0.25x \times 0.8y = 0.2xy$

Now we have to find the percent decreased

Subtract new product and original product and then divide by original product . Multiply the result by 100 to get percentage

$percent\ decrease = \frac{0.2xy - xy}{xy} \times 100\\\\percent\ decrease = \frac{-0.8xy}{xy} \times 100 = -0.8 \times 100 = -80$

Here negative sign denotes decrease

Thus the product has decreased by 80 %

A recipe for oatmeal cookies calls for 2 cups of flour for every 3 cups of oatmeal. How much flour is needed for a big batch of

kaheart [24]

6 cups of flour is needed for a big batch of cookies that uses 9 cups of oatmeal

Step-by-step explanation:

For 3 cups of oatmeal 2 cups of flour is required.

We need to find how much flour is needed for 9 cups of oatmeal.

Solving by using Unitary Method

3 cups of oatmeal require flour = 2 cups

1 cup of oatmeal require flour = $\frac{2}{3}$

9 cups of oatmeal require flour = $\frac{2}{3}*9\\$

= $6$

So, 6 cups of flour is needed for a big batch of cookies that uses 9 cups of oatmeal

Yuto and Lian are at train stations 1,880 kilometers apart. Yuto boards a train heading east at an average speed of 220 kilomete

ArbitrLikvidat [17]

For the answer to the question above, we'll have to use the formula for velocity which is v = d
 t and d = vt

Since the total distance is given, therefore we can get the time and it will look like this.

220t + 250t = 1880
470t = 1880
470 470
the problem indicates that the train runs 250kph
Let's substitute:

d = 250(4)

the distance traveled by Lian is 1000km
