Answer:

90

Step-by-step explanation:

90/10= 9

90/5= 18

No number larger than 90 would work.

Answer:

76

Step-by-step explanation:

(5x3)+(5x3)=30

15-6=9

5x9=45

45+30=75

Since 76 is the closest to 75 it's 76

D. (3x² + 10w + 8) square inches

Step-by-step explanation:

the new width of the rectangle: w + 2

the new length of the rectangle: 3w + 4

the area: (w + 2)(3w + 4) = 3w² + 10w + 8

There are 77 more third graders than there are second graders.

Step-by-step explanation:

You just have to subtract 338 from 415 to get your answer.

Answer:

Below in bold.

Step-by-step explanation:

As they are similar corresponding sides are in the same proportion so

3/2 = BC/3

2BC = 3*3

2BC = 9

BC = 4.5.

3/2 = 5/DF

3DF = 2*5

DF = 2*5 / 3

= 3.33...

Perimeter of ABC = 3 + 4.5 + 5 = 12.5.

Perimeter of DEF =  2 + 3 + 3.33.. = 8.33...

Answer:

BC = 4.5 cm

DF = 10/3 cm

Step-by-step explanation:

Corresponding sides of similar triangles are in same ratio

[tex]\frac{BC}{EF}=\frac{AB}{DE}\\\\\frac{BC}{3} =\frac{3}{2}\\\\BC = \frac{3}{2}*3\\\\BC = \frac{9}{2}\\\\BC = 4.5 cm[/tex]

[tex]\frac{DF}{AC}=\frac{DE}{AB}\\\\\frac{DF}{5}=\frac{2}{3}\\\\DF = \frac{2}{3}*5\\\\DF = \frac{10}{3}[/tex]

Perimeter of ΔABC = 3 + 5 +4.5 = 12.5cm

Perimeter of ΔDEF = 2 + 3 + 3.3 = 8.3 cm

Answer:

(–8, 1), (8, –8)

Step-by-step explanation:

Answer:

(-8, 1), (8, -8) has a negative slope

Step-by-step explanation:

1). y2 - y1 / x2 - x1

7 - 9 / 5 - 6

= 2

2). y2 - y1 / x2 - x1

6 - (-2) / 3 - (-9)

= 2/3

3). y2 - y1 / x2 - x1

-8 - 1 / 8 - (-8)

-9/16

4). y2 - y1 / x2 - x1

-9 - (-8) / -1 - 2

= 1/3

Step-by-step explanation:

A ratio is not necessarily a comparison between quantities with different units, quantities with the same units can be in a ratio in mathematics.

Answer:

D

Step-by-step explanation:

Decimal = "and"

2 decimal places = "hundredths"

Recall the double-angle identity,

sin²(x) = (1 - cos(2x)) / 2

Now if sin(12°) = k, then

k ² = sin²(12°) = (1 - cos(24°)) / 2

→   cos(24°) = 1 - 2k ²

The potential energy of a body can be found by using the formula

PE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 9.8 m/s²

We have

PE = 500 × 9.8 × 4

We have the final answer as

Answer:

.1km

Step-by-step explanation:

The tractor can move .01 km in a second so 10 times .01 is .1

so the tractor can move .1km every 10 seconds

1 hour = 3600 seconds

10 seconds is 10/3600 = 1/360 of an hour

36 km per hour x 1/360 of an hour = 0.1 km (100 meters)

Given:

When establishing the internet service, there was an initial fee as well as a monthly fee on the contract.

The given function is:

[tex]c(m)=35m+40[/tex]

To find:

The cost of internet service if they began service in March 2020.

Solution:

We have,

[tex]c(m)=35m+40[/tex]

We need to find the internet service cost for the first month. So, substitute [tex]m=1[/tex] in the given function.

[tex]c(1)=35(1)+40[/tex]

[tex]c(1)=35+40[/tex]

[tex]c(1)=75[/tex]

Therefore, the cost of internet service is 75 if they began the service in March 2020.

Answer:

0.45

Explanation:

the total probability of the spinner landing on red, blue or green is 0.20 + 0.12 + 0.08 = 0.40. thus, the remaining probability of the spinner landing on orange or pink is 1 - 0.40 = 0.60.

since the probability that the spinner will land on orange is three times that of pink, we can divide 0.60 by 3 + 1 to find the probability of it landing on pink:

0.60 ÷ 4 = 0.15

now, we can multiple this by 3 to find the probability that the spinner will land on orange:

0.15 × 3 = 0.45

The solution is, Rounding off 245,675 to the nearest hundred thousand is: 246000.

Rounding off means a number is made simpler by keeping its value intact but closer to the next number. It is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc.

here, given that,

Round 245,675 to the nearest hundred thousand

we know,

Anything at or above 50 gets rounded up.

49 and below gets rounded down.

so, we get,

here, to the nearest hundred thousand means 675 > 500

so, it will be 5,675 => 6000

we have,

Rounding off 245,675 to the nearest hundred thousand is:

246000

Hence, The solution is, Rounding off 245,675 to the nearest hundred thousand is: 246000.
