We know the sum of the interior angles is 720° for a hexagon.
Finding x
2(90)° + 2(5x + 10)° + 136° + 134° = 720°180° + 10x° + 20° + 270° = 720°10x° + 470° = 720°10x° = 250°x = 25Finding m∠ABC
∠ABC = 5x + 10∠ABC = 5(25) + 10∠ABC = 125 + 10∠ABC = 135°
Emilio is helping pass out modeling clay in art class. He takes three 2-pound bricks of clay
from the supply shelf. His job is to give each student 4 ounces of clay, but he runs out before
he can finish. If his class has a total of 28 students, how many more ounces of clay does he
need?
Answer:
16 ounces
Step-by-step explanation:
1 pound = 16 ounces. Each clay block is 2 pounds so each of them are 32 ounces.
32 x 3 = 96
Divide 96 by the 4 ounces for each student, 96 ÷ 4 = 24
The clay is only enough for 24 students, leaving 4 students out, each need 4 ounces, so multiply the 4 students by the 4 ounces.
4 x 4 = 16
Therefore, 16 ounces are needed. Hope this helped!

What are the coordinates of the y-intercept of the graph of y=–4x+5? (0, 5) (0, -5) (-5, 0) (5, 0)
Answer:
(0, 5)
Step-by-step explanation:
y = mx + b <== slope-intercept form of a straight line
m <== slope of the line
b = y-intercept (when x = 0)
y = -4x + 5
Therefore, for this line, the y-intercpet is (0,5)

A lab is monitoring the population of mice in a sample. Scientists noticed the number of mice triples every week. If there were initially 4 mice in the sample, how many mice will there be after 6 weeks?
A. 324 Mice
B. 972 Mice
C. 2916 Mice
D. 8748 Mice
C. 2916 Mice
Step-by-step explanation:
4 x 3^6 = 2916
Because as the mice increases, you triple that amount, instead of tripling 4 & multiplying by 6.
So, you're doing this instead:
4 x 3 = 12 (1 wk)
12 x 3 = 36 (2 wk)
36 x 3 =108 (3 wk)
108 x 3 = 324 (4 wk)
324 x 3 = 972 (5 wk)
972 x 3 = 2916 (6 wk)
Hope this helps!

Number of Calico Crayfish
Number of Blueback Herring
The dot plot with the least number of sites has the least frequency
The dot plot has the least number of sites is the Shield Darter
How to determine the dot plot?To determine the dot plot with the least number of sites, we simply calculate the total frequency of each dot plot
So, we have:
Shield Darter = 3 + 1 + 4 + 2 + 3 + 1 + 1
Shield Darter = 15
Calico Crayfish = 1 + 1 + 3 + 4 + 1 + 2 + 4 + 2
Calico Crayfish = 18
Zebra Mussel = 1 + 3 + 2 + 5 + 1 + 1 + 2 + 3 + 2
Zebra Mussel = 20
Blue back Herring = 3 + 3 + 2 + 1 + 3 + 1 + 4
Blue back Herring = 17
From the computation above, the least frequency is
Shield Darter = 15
Hence, the dot plot has the least number of sites is the Shield Darter

A movie premiere had a full house of 350 film buffs. The price of the tickets was $6 for adults and $4 for underage. The income from ticket sales was $1,600. What is the number of adult's, x, who attended?
A 80
B 140
C 100
D 250
Answer:
C
Step-by-step explanation:
let x be number of adults and y the number of underage , then
x + y = 350 → (1)
6x + 4y = 1600 → (2)
multiplying (1) by - 4 and adding to (2) will eliminate y
- 4x - 4y = - 1400 → (3)
add (2) and (3) term by term to eliminate y
(6x - 4x) + (4y - 4y) = 1600 - 1400
2x + 0 = 200
2x = 200 ( divide both sides by 2 )
x = 100
the number of adults who attended is 100
Which statements are true about the polynomial 28vw 49v 35w? check all that apply. the coefficients have no common factors other than 1. there are no common variables among all three terms. the gcf of the polynomial is 7v. each term written as the product, where one factor is the gcf, is 7(28vw) 7(49v) 35(w). the resulting expression when factoring out the gcf is 7(4vw 7v 5w).
The statements that are true about the considered polynomial are:
Option 2: There are no common variables among all three termsOption 5: The resulting expression when factoring out the gcf is 7(4vw+7v+5w)How to find Greatest common factor?Greatest common factor, as the name implies, is greatest among all common factors among the quantities given.
We can factorize the quantities in smallest relative factors possible (one level of factors over which all quantities can form themselves), and collect as many common factors as we could. Those will together compose GCF(Greatest common factor).
The considered polynomial is: 28vw + 49v + 35w
Checking all the options:
Option 1: The coefficients have no common factors other than 1False.
Coefficients are numbers in multiplication with variables in each term.
The coefficients of the considered polynomial are 28, 49, 35
They are all multiple of 7 and 1, so the common factor is 7 too, along with 1.
Option 2: There are no common variables among all three termsYes its true.
It is because none of the variables v, or w are in all the three terms.
Option 3: The gcf of the polynomial is 7v.False.
First term = 28vw = [tex]7\times 4 \times v \times w[/tex]Second term = 49v = [tex]7\times 7 \times v[/tex]Third term = 35w = [tex]7 \times 5 \times w[/tex]Thus, the greatest factor that is common in all three terms is 7 and not 7v.
Option 4: Each term written as the product, where one factor is the gcf, is 7(28vw) 7(49v) 35(w)False.
Because, each term written as product of gcf gives:
First term = 28vw = [tex]7\times 4vw[/tex]Second term = 49v = [tex]7\times 7v[/tex]Third term = 35w = [tex]7 \times 5w[/tex]Option 5: The resulting expression when factoring out the gcf is 7(4vw+7v+5w)True.
It is because:
[tex]7(4vw+7v+5w) = 28vw + 49v + 35w[/tex] = the considered polynomial, and that 7 is the gcf.
Thus, the statements that are true about the considered polynomial are:
Option 2: There are no common variables among all three termsOption 5: The resulting expression when factoring out the gcf is 7(4vw+7v+5w)Learn more about greatest common factor here:

Answer:

There are no common variables among all three terms. <----
The GCF of the polynomial is 7v.
Each term written as the product, where one factor is the GCF, is 7(28vw) + 7(49v) + 35(w).

The ordered pair maximizes the objective function p = 3x + 8y will be (5, 6) .Option C is correct.
What is the objective function?The objective function is simply an equation that represents the goal production capability that relates to maximizing profits in relation to manufacturing.
On putting the values we will get the values one by one. We get;
1. (0, 0)
[tex]3 (0)+8(0) = 0[/tex]
2. (2,7)
[tex]3(2)+8(7)=62[/tex]
3. (5,6)

A number line from negative 3 to 3 in increments of 1. An open circle is at negative 5 and a bold line starts at negative 5 and is pointing to the left.
The solutions are all the points strictly larger than 5, to represent this, we draw an open circle at x = 5, and a bold line that points to the right.
How to represent the inequality?
Here we have the inequality:
–3(2x – 5) < 5(2 – x)
First, we need to isolate x in one side of the inequality, we will get:
-6x + 15 < 10 - 5x
15 - 10 < -5x + 6x
5 < x
Then the solutions are all the points strictly larger than 5, to represent this, we draw an open circle at x = 5, and a bold line that points to the right.
