Answer:

2/9 yards

Step-by-step explanation:

Felicity cuts 27 equal strips from a 6-yard spool of ribbon. Which expressions show the number of yards for one strip of ribbon

From the above question:

27 equal strips of ribbon = 6 yards of spool

1 strip of ribbon = x yards

Cross Multiply

27 strips of ribbon × x yards = 6 yards × 1 strip of ribbon

x yards = 6/27

x yards = 2/9 yards

Therefore, for 1 strip of ribbon we need 2/9 yards

Answer: (x−3)(x+7)

Step-by-step explanation:

=(x+−3)(x+7)

=(x)(x)+(x)(7)+(−3)(x)+(−3)(7)

=x^2+7x−3x−21

=x^2+4x−21

Answer:

A. X^2+4x-21

Step-by-step explanation:

(x−3)(x+7)

=(x+−3)(x+7)

=(x)(x)+(x)(7)+(−3)(x)+(−3)(7)

=x2+7x−3x−21

=x2+4x−21

Answer: 21 degrees

Step-by-step explanation:

In the evening, the temperature is 28 degrees and by midnight it has dropped 31 degrees lower, the temperature by midnight will be:

= 28° - 31°

= -3°

Between midnight and 4 am it goes down 6 more degrees. The temperature by 4am will be:

= -3° - 6°

= -9°

Then, by 9 am, the temperature goes up 30 degrees, the temperature at 9 am will then be:

= -9° + 30°

= 21°

Answer:

DE = 5

BC = 10

Step-by-step explanation:

ΔAED is a right triangle with legs of 4 and 6/2 = 3

Use the Pythagorean theorem to find DE

[tex]4^{2} + 3^{2} = DE^{2}[/tex]

16 + 6 = 25 = [tex]DE^{2}[/tex]

DE = 5

The midsegment of a triangle is 1/2 the length of the corresponding side.

Therefore, BC = 2 DE = 2(5) = 10 = BC

Answer:

Write the expression as a – 90

Simplify by subtracting 90 from 102.

The answer is 12.

Step-by-step explanation:

Write and evaluate the expression. Then, check all that

Answer:

x=8

Step-by-step explanation:

If the triangle is isosceles, it means that 2 of its sides are equal in length, therefore its perimeter is equal to

[tex](2x - 3) + (2x - 3) + (x)[/tex]

Adding similar terms, and recalling that the perimeter is equal to 34, we get

[tex]5x - 6 = 34 \\ 5x = 40 \\ x = 8[/tex]

Answer:

2.58

Step-by-step explanation:

129/50 = 2.58

Number equivalent to 129 /50 is 2.58 .

Given,

129 divided 50

Using division property,

The rules for division are:

(1) positive × or ÷ positive = positive

(2) positive × or ÷ negative = negative

(3) negative × or ÷ negative = positive

Rule for long division method,

Divide the tens column dividend by the divisor.

Multiply the divisor by the quotient in the tens place column.

Subtract the product from the divisor.

Bring down the dividend in the ones column and repeat.

Therefore,

divide, multiply, subtract, bring down and repeat or find the remainder.

Here the required value is of :

129/50

= 2.58

Hence the answer is2.58

Step-by-step explanation:

Given

- 5x + 3 = 2x - 1

or, 2x + 5x = 3 + 1

or, 6x = 4

or, x = 4/ 6

Therefore x = 2 /3

Answer: 12 packages

Step-by-step explanation:

Take 175 and divide it by 15

175/15

You will get 11.6

Since you are unable to order 11.6 packages you will need to order 12 packages to have enough lightbulbs.

Answer:

the school would need to buy 12 pack and that will give them 180 light bulbs they will have 5 leftover

Answer:

tanA = 40/9

Step-by-step explanation:

Try to construct a right-angled triangle with it's adjacent side=9 and hypotenuse = 41,

By pyth. theorem, we can get the remaining side (opposite side)

= √(41^2 - 9^2)

= 40

tanA = oppside side/ adjacent side

tanA = 40/9

Answer:

13

Step-by-step explanation:

Since all the sides of a cube are equal, one single side will be the cube root of the volume i.e,2197 to give me 13
