Answer:

True

Step-by-step explanation:

The base angles of an isosceles triangle are equal.

The sum of the 3 angles in a triangle = 180°, thus

vertex angle = 180° - (55 + 55)° = 180° - 110° = 70°

A rectangle with sides 15 and w has perimeter

[tex]2p = 2(15+w) = 2w+30[/tex]

We want this quantity to be at most 50, so it must be less than or equal to 50:

[tex]2w+30\leq 50[/tex]

For the record, this implies that

[tex]2w\leq 20 \iff w \leq 10[/tex]

So, the width can be at most 10.

Answer:

well, 5/7 is not the negative reciprocal of -1.

Check the picture below.

so, bearing in mind that vertical angles are equal, thus ∡AED = ∡BEC, and we know that ∡BEC = 52 = ∡AED, so those two angles added up are 104°.

now, a circle has a total of 360°, if we take away those 104° from the red angles, what's leftover is just 256°, well, the green angles there are also vertical angles and thus twins, so each one will take half of 256°.

∡BEA = 128° = ∡CED.

Answer: We start with 6 reams of copy paper and 8 teachers.

a) if we distribute the paper equally between all the teachers, then each teacher receive 6/8  (here we are dividing the total number of reams by the number of people that we are are splitting it). but 6/8 is less than one, so we must open the reams in order to split them.

b) If there were twice as many reams of paper, then we will have 2*6 = 12 reams of paper, and if there where half the number of teachers, then we have 8/2 = 4 teachers.

Doing the same procedure as before, we have 12 teams for 4 teachers, then each teacher has 12/4 = 3 reams

before, each teacher received 6/8 reams, and now, each one receive 3.

if we want to know the change, we need to see the difference between these numbers, so 3 - 6/8 =  3*8/8 - 6/8

notice that i am multiplying the 3 by 8/8, this is one, but  this way i can have the same denominator in both numbers.

24/8 - 6/8 = 18/8 = 9/4 = 8/4 + 1/4 = 2 + 1/4

so each teacher receive 2 + 1/4 reams than before.

Answer:

a ) total number of sixth in 5 ribbon will be 6\times 5 = 30

b) length of each sixth will be = 5.97 inches

Step-by-step explanation:

given data:

Number of pieces of ribbon is 5

each piece length 1 yard

total number of cut in one piece of ribbon = 6

a) one piece of ribbon consist of 6 sxiths

therefore total number of sixth in 5 ribbon will be 6\times 5 = 30

b) each ribbon length is 1 yard

so, whole ribbon is divided into 1\6 yard length which is length of individual division

we know that one yard is 36 inches

therefore, in 1/6 yard = 5.97 inches

Answer:

a.  She will have 30 sixths after cutting all the ribbons.

b. 6 inches.

Step-by-step explanation:

a. You know that the lenght of each piece of ribbon is 1 yard.

She cuts each ribbon into sixths, then the lenght of each one of them is:

[tex]\frac{1}{6}\ yd[/tex]

So:

[tex]\frac{6}{6}=1\ yard[/tex]

Since Faye has 5 pieces of ribbon, after cutting all the ribbons she will have:

[tex](5)(\frac{6}{6})=\frac{30}{6}[/tex]

She will have 30 sixths after cutting all the ribbons.

b. You need make the conversion from yards to inches.

Knowing that [tex]1\ yd=36\ in[/tex], you get:

[tex](\frac{1}{6}\ yd)(\frac{36\ in}{1\ yd})=6\ in[/tex]

Step-by-step explanation: To find the decimal that is equivalent to 7/12, remember that fractions are division problems so we can divide the numerator by the denominator.

Numerator = 7

Denominator = 12

7 ÷ 12 = 0.58333333333333.

Answer:

Answer:

840,000 / 306,000 = 2.7450980392

So, Greenland is about 2 and 3/4 times larger than New Guinea.

Step-by-step explanation:

Greenland, the largest island in the world, is 534,000 square miles larger than New Guinea.

Greenland is 840,000 square miles and New Guinea is 306,000 square miles. To find out how much larger Greenland is than New Guinea, we subtract the area of New Guinea from the area of Greenland:

840,000 - 306,000 = 534,000 square miles

Therefore, Greenland is 534,000 square miles larger than New Guinea.

To determine how much larger Greenland is than New Guinea, one must subtract the size of New Guinea from the size of Greenland. Given that Greenland, the largest island in the world, is 840,000 square miles and New Guinea is 306,000 square miles, you would perform the following calculation:

840,000 - 306,000 = 534,000 square miles

Therefore, Greenland is 534,000 square miles larger than New Guinea.

Step-by-step explanation:

Multiply through by the lowest common multiple of u, v and f, that is uvf

uvf × [tex]\frac{1}{v}[/tex] + uvf × [tex]\frac{1}{u}[/tex] = uvf × [tex]\frac{1}{f}[/tex], that is

uf + vf = uv ← factor out f on the left side → (1)

f(u + v) = uv ← divide both sides by (u + v)

f = [tex]\frac{uv}{u+v}[/tex]

Using line (1)

uf + vf = uv ( subtract uv from both sides )

uf + vf - uv = 0 ( subtract uf from both sides )

Answer:

(a). $20,000

(b). The estimate will be lower than the actual amount.

Step-by-step explanation:

We have been given that Michael saves $423 dollars a month for college.

(a). We know that 1 year equals 12 months.

4 years = 4*12 months = 48 months.

[tex]\text{Actual amount saved}=\$423\times 48[/tex]

Since we are asked to find the estimated amount of money Michael will save in 4 years, so we will estimate both quantities as:

[tex]423\approx 400\\\\48\approx 50[/tex]

[tex]\text{Actual amount saved}=\$400\times 50[/tex]

[tex]\text{Actual amount saved}=\$20,000[/tex]

Therefore, Michael will save approximately $20,000 in 4 years.

(b).

The estimate will be lower than the actual amount as we rounded $423 down $23 to nearest hundred that is $400 and rounded 48 up 2 to nearest ten that is 40.

Therefore, the estimate will be lower than the actual amount.

Answer:

A. One pound of pistachios plus 1 pound of almonds cost $20

C. Reducing the number of pounds of almonds by 1 results in a total cost of $40.

E. The cost p, in dollars, of 1 pound of pistachios is modeled by 2p + 3(p – 4) = 48.

Step-by-step explanation:

Let

x ----> the cost of one pound pistachios

y ----> the cost of one pound of almonds

we know that

x=y+4 -----> equation A

2x+3y=48 -----> equation B

substitute equation A in equation B and solve for y

2(y+4)+3y=48

2y+8+3y=48

5y=48-8

y=8

Find the value of x

x=8+4 =12

therefore

The cost of one pound pistachios is $12 and the cost of one pound of almonds is $8

Verify all statements

case A) One pound of pistachios plus 1 pound of almonds cost $20.

Is True

x+y=$12+$8=$20

case B) The pistachios cost twice as much per pound as the almonds

Is false

Because

2y=2(8)=$16

$16≠$12

case C)  Reducing the number of pounds of almonds by 1 results in a total cost of $40

Is True

Because

2x+2y=2(12)+2(8)=$40

case D) The cost a, in dollars, of 1 pound of almonds is modeled by 2(a – 4) + 3a = 48.

The equation will be

2(a + 4) + 3a = 48.

case E) The cost p, in dollars, of 1 pound of pistachios is modeled by 2p + 3(p – 4) = 48

Is true
