Answer:

B. $5*\frac{1}{7}$

Step-by-step explanation:

5÷7 is also $\frac{5}{7}$ --that divided sign is what the fractional bar represents in a fraction.

now multiply $5*\frac{1}{7}=\frac{5}{1}*\frac{1}{7}=\frac{5*1}{1*7}=\frac{5}{7}$

both are the same result, so your answer is Choice B.

ale4655 [162]

For this case the first thing we should do is find the percentage of people surveyed who said that pizza pizza was their favorite type of pizza.
We have then:
$x = (21/40) * (100)

x = 52.5%$
We are now looking for 52.5% of 1600 people.
For this, we make the following rule of three:
1600 ----------> 100%
x ---------------> 52.5%
Clearing the value of x we have:
$x = (52.5 / 100) * (1600)

x = 840$
Answer:
the most reasonable estimate for the number of Trinity Food Festival attendees whose favorite type of pizza is sausage pizza is:
x = 840

Look at the figure, O PORS. Find the mZP, 12 36° 140" 144"

bogdanovich [222]

m∠P = 144°

Solution:

PQRS is a parallelogram.

m∠P = 12a°, m∠Q = (4a - 12)° and m∠S = 3a°

In parallelogram, opposite angles are congruent.

m∠Q = m∠S

4a° - 12° = 3a°

Add 12° on both sides.

4a° - 12° + 12° = 3a° + 12°

4a° = 3a° + 12°

Subtract 3a° on both sides.

4a° - 3a° = 3a° + 12° - 3a°

a° = 12°

To find the measure of angle P:

m∠P = 12a°

= 12(12°)

m∠P = 144°

mina [271]

Answer:

b. 1; 16; 121; 13,456

Step-by-step explanation:

A suitable calculator or spreadsheet can compute these for you.

Put the value of x into the formula to find the first iterate. Repeat for successive iterates.

Comment on the answer choices

You can eliminate the first two answer choices because none of the numbers 19, 645, 12645 are perfect squares. You can eliminate the last answer choice because the first term listed is x0, not x1.

13 R S 12 What's the length of QR? A) 1 B) 17.7 C) 6.7 OD) 5

ANEK [815]

Answer:

Step-by-step explanation:

This is a right triangle, so we can use the Pythagorean theorem

a^2+b^2 = c^2

where a and b are the legs and c is the hypotenuse

QR^2 + 12^2 = 13^2

QR^2 +144 =169

QR^2 = 169-144

QR^2 =25

Take the square root of each side

QR = sqrt(25)

QR =5

MrRa [10]

Answer:

Option (2). None

Step-by-step explanation:

A quadrilateral ABCD has been given with a property,

m∠7 = m∠4

Option (1). AB║ DC

For AB║DC, angle 7 and angle 3 should measure the same.

(By the property of alternate angles)

Therefore, by the given property we can not deduce AB║DC.

Option (3). AD║BC

For AD║BC, angle 7 and angle 3 must be equal in measure.

(By the property of alternate angles)

Therefore, by the given property we can not deduce AD║DC

Option (2). None will be the answer.
