Answer:
[tex]ABC = 130[/tex]
Step-by-step explanation:
Given
[tex]ABC=12x - 110[/tex]
[tex]ABD=3x+40[/tex]
[tex]DBC=2x - 10[/tex]
Required
Determine the measure of ABC --- Missing part of the question
First, we need to determine the value of x
Since, D is an interior of ABC, then
[tex]ABC = ABD + DBC[/tex]
[tex]12x - 110 = 3x + 40 + 2x - 10[/tex]
Collect Like Terms
[tex]12x - 3x - 2x = 110 + 40 - 10[/tex]
[tex]7x = 140[/tex]
Solve for x
[tex]x = 140/7[/tex]
[tex]x = 20[/tex]
Substitute 20 for x in [tex]ABC=12x - 110[/tex]
[tex]ABC = 12 * 20 - 110[/tex]
[tex]ABC = 240 - 110[/tex]
[tex]ABC = 130[/tex]

Answer:
h = (A - 9)/6
Step-by-step explanation:
Step 1: Define
A = b² + 2bh
b = 3
Step 2: Substitute
A = (3)² + 2(3)h
Step 3: Evaluate and solve for h
A = 9 + 6h
A - 9 = 6h
(A - 9)/6 = h

Jacque needs to buy some pizzas for a party at her office. She's ordering from a restaurant that charges a $ 7.50 $7.50dollar sign, 7, point, 50 delivery fee and $ 14 $14dollar sign, 14 per pizza. She wants to buy as many pizzas as she can, and she also needs to keep the delivery fee plus the cost of the pizzas under $ 60 $6
Answer:
5 pizzas Sorry i may be wrong
Step-by-step explanation:
The inequality that models this situation is given by:
[tex]7.5 + 14p \leq 60[/tex]
--------------------------------
The first step towards building the inequality is finding Jacque's total spending.The delivery, which if a fixed fee(paid only once), is $7.50.Then, each pizza will cost $14, thus, the cost of buying p pizzas is [tex]14p[/tex].Thus, the total spending is of:[tex]T = 7.5 + 14p[/tex]
--------------------------------
He wants the cost under $60, and thus:[tex]T \leq 60[/tex]
Since [tex]T = 7.5 + 14p[/tex], the inequality is:
[tex]7.5 + 14p \leq 60[/tex]

if 1 and -3 are the zeroes of the polynomial xcube - axsquare - 13x + b find the values of a and b
Step-by-step explanation:
f(x) = x³ - ax² - 13x + b.
f(1) = 1³ - a(1)² - 13(1) + b = 0
=> 1 - a - 13 + b = 0, b - a - 12 = 0.
f(-3) = (-3)³ - a(-3)² - 13(-3) + b = 0
=> - 27 - 9a + 39 + b = 0, 12 - 9a + b = 0.
Therefore, b - a - 12 = 12 - 9a + b. 8a = 24, a = 3.
=> b - (3) - 12 = 0, b = 15.
Emanuel works as a car salesman. He makes $13 an hour plus a commission of 5% on all cars he sells. Last month he worked 40 hours and sold cars worth $120,000. How much did he make last month?
Answer:
$6520
Step-by-step explanation:
salary = hourly rate * hours + 5% of sales

salary = $520 + $6000
salary = $6520

She buys twice as many balls as bats. She spends $131 in total, which
includes $8 tax. Which equation would you use to find the number of bats she
buys?
Let x represent the number of bats she buys.
Given :
Cost of each ball , $3.

If BC = 35 and AC =52 , find AB
Answer:
AB = 47 (answers may vary)
Step-by-step explanation:
BC = 35
AC = 52
C, in fact, can be any number you choose less than 35;
For example,
C= 20
35 - 20 = 15
B = 15
52 - 20 = 32
A = 32
AB = 32 + 15 = 47

The tree diagram shows all the possible combinations for heads (H) and tails (T) when 3 coins are tossed. What is the probability that the outcome has at least two heads?
Answer:
No diagram so I'll make one:
H H H

H T H
T H H
T T H
T H T
H T T
T T T
There are 8 possible outcomes and four of these have 2 heads.
Probability = 4 / 8 = .50
Step-by-step explanation:
Probability of getting at least two heads after tossing 3 coins is equals to (1 / 2).
What is probability?" Probability is defined as a mathematical statement which represents the ratio of number of favourable outcomes to the total number of outcomes."
Formula used
Probability = [tex]\frac{Number of favourable outcomes}{Total number of outcomes}[/tex]
According to the question,
Number of coins tossed =3
As shown in the tree diagram drawn we have,
Total number of outcomes = 8
At least two heads means 2 or more than two
Here.
HHH, HHT,HTH, THH
Number of favourable outcomes of getting at least two heads = 4
Substitute the value in the formula of probability we get,
Probability = (4 / 8)
= ( 1 / 2)
Hence, probability of getting at least two heads after tossing 3 coins is equals to (1 / 2).
