Answer:

5.25 hours

Step-by-step explanation:

So in a week there is 7 days and we know she reads EACH night 0.75  so we know we have to multiply:

0.75 x 7= 5.25

So In one week or 7 days she read 5.25 hours.

Answer:

x=27

∠JLK=2x+1=2(27)+1=55

Step-by-step explanation:

∠A+∠K=180

3x+13+∠K=180

∠K=167-3x

∠K+∠L+∠J=180

167-3x+39+2x+1=180

207-x=180

x=27

∠JLK=2x+1=2(27)+1=55

Don't worry, you aren't gonna fail. Take a deep breath and relax. Geometry is tricky but you got this. Have a nice night.

894 square miles

Step-by-step explanation:

The area of a parallelogram is base•height. In this case the base is 37.25 and the height is 24 (the parallelogram. is sideways). 37.25•24=894.

Answer:

f(x) = -3x +2 to find f(4) you plug in the value of x=4 in the function

f(4) = -3(4) +2

= - 12 +2

=- 8

Hope it is helpful to you

The value of the linear function at x = 4 will be 14.

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The function is given below.

f(x) = 3x + 2

The degree of the function is one. Then the function is a linear function.

The value of the function at x = 4 will be given as,

f(4) = 3(4) + 2

f(4) = 12 + 2

f(4) = 14

The value of the linear function at x = 4 will be 14.

Answer: B

Step-by-step explanation:

In this equation, you must find the common denominator of each fraction, and subtract them.

Given:

3/8b - 3/4b

Step 1: Find the common denominator

As 4 is a factor of 8, multiply the entire fraction by 2 to get the common denominator.

3/8b - 2(3/4b)

3/8b - 6/8b

This is the proper equation

Step 2: Solve

Subtract 6/8b from 3/8b to get the solution

3/8b - 6/8b = -3/8b

The answer is B

Answer:

None of them are correct

Answer: 14%

Step-by-step explanation:

From the question, we are informed that Bobby guessed there were 92 jelly beans in a jar when there were actually 107. The percentage error will be:

= Difference in error / Actual value × 100

= (107 - 92) / 107 × 100

= 15/107 × 100

= 0.14 × 100

= 14%

Answer:

The correct option is;

0.01 and (1 × 1/100)

Step-by-step explanation:

The given parameters includes;

The batting average of Yordan Alvarez's = 0.317

Therefore, we have;

The digit in the hundredths place = 0.01

The expanded notation for the value of the hundredth place is given by the product of the digit and the place value digit as follows;

The expanded notation = 1 × 1/100.

b) (-3,0) (-1,0)

Step-by-step explanation:

It tells you on the graph

Answer:

a) I think the turning point is max or min correct? If so, the min of the function is (-2, -1) AKA the vertex

b) I also think the roots are just another way to say the x-intercepts so in that case, the roots are (-1, 0) and (-3, 0)

Answer:

five planes appear in the figure

Okay so not super crazy but one night me, my brothers, my cousin, and a few friends from our campground stayed up all night and walked in the rain. Not the crazy part though obviously. It was pouring and we got to the complete opposite side of the camp and through the woods and thought it was a good idea to go to the 'abandoned bathrooms" at like 2 in the morning. So we walked through the woods and made it there, we then found that someone boarded it up so you couldn't enter the bathrooms anymore. My older brother found a crowbar on the ground and beat the hecc out of the boys side boards until we could go in. We went in and messed around for a bit. We didn't make it home until the early hours of the morning. It was really fun and we got to scare my cousin lol

Answer:

[tex]m\angle S = 35^\circ, \ m\angle T = 105^\circ,\ m\angle R = 105^\circ[/tex]

Step-by-step explanation:

Similar Triangles

Lines ST and QR are parallel. Thus, angles S and Q are congruent, and angles T and R are congruent.

Considering the triangle PQR, the sum of its internal angles must be 180°:

[tex]m\angle P + m\angle Q + m\angle R = 180^\circ[/tex]

Substituting the known values:

[tex]40^\circ + 35^\circ + m\angle R = 180^\circ[/tex]

Solving for R:

[tex]m\angle R = 180^\circ - 40^\circ - 35^\circ[/tex]

[tex]m\angle R = 105^\circ[/tex]

Angles S and Q are congruent, thus

[tex]m\angle S = 35^\circ[/tex]

Angles T and R are congruent, thus

[tex]m\angle T = 105^\circ[/tex]

Summarizing:

[tex]\mathbf{m\angle S = 35^\circ, \ m\angle T = 105^\circ,\ m\angle R = 105^\circ}[/tex]
