Find the difference in length between a walking stick and a bumblebee PLS HELP HURRY

Tanya [424]

Difference between the lengths of walking stick and lengths of bumble bee is $3\frac{4}{8}$ inch.

Solution:

Given data represents the length of the insects.

Length of the walking stick = 4 in

Length of the bumble bee = $\frac{5}{8}$ in

Difference between their length

$$=4-\frac{5}{8}$

$$=\frac{4}{1} -\frac{5}{8}$

To make the denominator same, multiply and divide the first term by 8.

$$=\frac{32}{8} -\frac{5}{8}$

$$=\frac{32-5}{8}$

$$=\frac{27}{8}$

Now, change improper fraction into mixed fraction, we get

$$=3\frac{4}{8}$

Difference between the lengths of walking stick and lengths of bumble bee is $3\frac{4}{8}$ inch.

Which is a correct two-column proof? Given: <H and <X are supplementary. prove: l || n

andriy [413]

Answer:

option-B

Step-by-step explanation:

we are given

<H and <X are supplementary angles

so,

<H+<X=180

we know that

<H and <E are vertically opposite angles

so, they must be equal

<H=<E

we can plug it

<E+<X=180

It means that angle(E) and angle(X) are supplementary angles

and these two angles are same side interior angles

By using same side interior angles converse

so, line(l) and line(n) must be parallel

so, option-B

kelly takes pam shopping for new clothes. shirts cost $12 and pants cost $21. Pam spends a total of $240 on 14 new items. how ma

ArbitrLikvidat [17]

Let’s call the amount of pants x and the amount of shirts y.
12y + 21x = 240
y + x = 14 which could be changed to x= 14-y

now you plug it into the first equation
12y + 21 (14 - y) = 240
12y + 294 - 21y = 240

add the similar terms
12y - 21y = 240 - 294
-9y = -54

cancels the minus signs on both sides
9y = 54
y= 6

now you plug y = 6 into the equation x = 14-y
x = 14 - 6
x = 8

answer: Pam bought 8 pants and 6 shirts
