Evaluate the expressions 56 with a variable of -1

Answers

Answer 1

Answer:

The expression 56 with a variable of -1 is not well defined. The term 56 is a constant number, and the variable of -1 is also a constant. Therefore there is nothing to evaluate.

Step-by-step explanation:

If you want to evaluate the expression 56*(-1) it would give -56 as output because -1 is a scalar and multiplying with a scalar will change the sign of the constant 56 but it won't change its value.

In other words, to evaluate an expression, it needs to have a mathematical operation or function, operands, and/or variables that can be replaced with values or expressions. Without any operation, there's nothing to evaluate.

70=p

Answer:

Q1. a) q= 9.6

b) q= 84

Q2. a) p= 10

b) p= 70

Step-by-step explanation:

Substitute the equation with the given value and solve the equation to arrive at the answer.

Q1. a) q= 4 +0.8p

When p= 7,

q= 4 +0.8(7)

q= 4 +5.6

q= 9.6

b) q= 4 +0.8p

When p= 100,

q= 4 +0.8(100)

q= 4 +80

q= 84

Q2. a) q= 4 +0.8p

When q= 12,

12= 4 +0.8p

0.8p= 12 -4 (-4 on both sides)

0.8p= 8

p= 8 ÷0.8 (÷0.8 on both sides)

p= 10

b) q= 4 +0.8p

When q= 60,

60= 4 +0.8p

0.8p= 60 -4 (-4 on both sides)

0.8p= 56

p= 56 ÷0.8 (÷0.8 on both sides)

p= 70

What is the slope of the line that passes through the points (-4, -6) and (1, -6)? Write your answer in simplest form

Answers

The slope of the line that passes through the points (-4, -6) and (1, -6) is zero and hence the line is parallel to the x-axis.

What is slope?

The slope is the rate of change of the y-axis with respect to the x-axis.

The equation of a line in slope-intercept form is y = mx + b, where

slope = m and y-intercept = b.

We know the greater the absolute value of a slope is the more steeper is its graph or rate of change is large.

We know slope(m) = (y₂ - y₁)/(x₂ - x₁).

Therefore, The slope of the line that passes through the points (-4, -6) and (1, -6) is,

m = (- 6 + 6)/(- 4 - 1).

m = - 0/5.

m = 0.

As the slope is equal to zero the line is parallel to the x-axis.

D.

Answers

Answer:

A

Explanation:

If you graph the points and connect them, you'll see the triangle they're asking about. Yhe base of the triangle is 9 and the height is 8. The area of a triangle is half of the base times the height. So multiply 8 by 9 and you get 72. This is twice the area. So divide it by 2 and you get 36, which is the area of the triangle. So the answer is A.

The measurement of the hypotenuse is obtained as 9 units using the Pythagoras theorem.

What is Pythagoras Theorem?

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side.

According to the graph -

The perpendicular measures 4 units.

The base measures 3 units.

To find the hypotenuse g apply the Pythagoras theorem -

(hypotenuse)^2=(base)^2+(perpendicular)^2

(g)^2=(3)^2+(4)^2

(g)^2=9+16

(g)^2=25

g=[tex]\sqrt{25}[/tex]

g=5

In baseball, each time a player attempts to hit the ball, it is recorded. The ratio of hits compared to total attempts is their batting average. Each player on the team wants to have the highest batting average to help their team the most. For the season so far, Jana has hit the ball 7 times out of 10 attempts. Tasha has hit the ball 10 times out of 16 attempts. Which player has a ratio that means they have a better batting average?

Tasha, because she has the lowest ratio since 0.7 < 0.625
Tasha, because she has the highest ratio since 56 over 80 is greater than 50 over 80
Jana, because she has the highest ratio since 56 over 80 is greater than 50 over 80
Jana, because she has the lowest ratio since 0.7 < 0.625

Answers

Answer: The correct answer is C. Jana has a higher ratio of hits to total attempts, so she has a better batting average. This can be calculated by dividing the number of hits by the number of attempts: Jana's batting average is 7/10 = 0.7, and Tasha's batting average is 10/16 = 0.625. Since 0.7 is greater than 0.625, Jana has a higher batting average.

Jana has a better batting average, because she has a higher ratio of hits to total attempts. You can find the batting average for each player by dividing the number of hits by the number of attempts. In this case, Jana's batting average is 7 hits / 10 attempts = 0.7, and Tasha's batting average is 10 hits / 16 attempts = 0.625. Since 0.7 is greater than 0.625, Jana has a higher batting average.

Step-by-step explanation:

Stratified Sampling is a form of sampling in which the researcher selects a population sample based on a demographic factor or strata such as race or gender. From the different strata, a random sample is then made such that each group or subpopulation is represented in the final sample.

It should be noted that retaining the percentages while selecting a randomized sample is essential to stratified sampling.

Hence, in this case, when the researcher obtains a list of all enrolled freshmen, manipulates the list so that females appear twice as often as males, and then selects from this list, this is an example of stratified sampling

Given:

The figure of a rhombus.

To find:

The measure of angle 1.

Solution:

First label the vertices of the rhombus as shown in the below figure.

We know that the opposite angles of a rhombus are congruent and the diagonals of a rhombus bisect each vertex angle.

[tex]m\angle ABD=m\angle CBD=30^\circ[/tex]       (Diagonal BD is the angle bisector)

Now,

[tex]m\angle ABC=m\angle ABD+m\angle CBD[/tex]  

[tex]m\angle ABC=30^\circ+30^\circ[/tex]

[tex]m\angle ABC=60^\circ[/tex]  

We know that the consecutive angles of a rhombus are supplementary. It means the sum of each pair of consecutive angles is 180 degrees.

[tex]m\angle BAD+m\angle ABC=180^\circ[/tex]

[tex]m\angle 1+60^\circ=180^\circ[/tex]

[tex]m\angle 1=180^\circ-60^\circ[/tex]

[tex]m\angle 1=120^\circ[/tex]

Therefore, the measure of angle 1 is [tex]m\angle 1=120^\circ[/tex].

8⁶/8⁻⁵8¹¹

Step-by-step explanation:

When increasing the power of an integer by another power, you should multiply both powers to find the total power that the integer should be raised to. In this case therefore:

= 3 * 2

= 6

So the numerator will be 8⁶

When dividing the same integers raised to powers, you should subtract the power of the divisor from the power number being divided.

In this case therefore, you are to subtract (-5) from 6 (calculated in first part).

= 6 - (-5)

= 6 + 5

= 11

Another way of writing the above will therefore be: 8¹¹.
