Answer:
270 minutes in all
Step-by-step explanation:
First, if we know that Deena spent 45 min painting, and that Clara spent 30 min more, than to find how much Clara painted you do 45 + 30 which equals 75. To find Adam, you do 75 x 2 which = 150.
150 + 75 + 45 = 270
Hope this helps!

-158=-8-5m
Answer:
Step-by-step explanation: -8 - - 158= 5
=>5m=150
=>m=30
Step-by-step explanation:
1. Rearrange term
-158=-8-5m
-158=-5m -8
2. Add 8 to both sides of the equation
-158=-5m -8
-158+8=-5m -8=8
3. Simplify
-158+8=−5m−8+8
−150=−5m-8+8
−150=−5m−8+8
−150=−5m
4. Divide both sides of the equation by the same term
−150=−5m
−150=−5m
-5 -5
5. Simplify

Answer:
Sin A = 5/13; tan C = 12/5
Step-by-step explanation:
Sin = opposite / hypotenuse. The opposite of A is 5, and the hypotenuse is 13, therefore Sin A = 5/13.
Tan = opposite / adjacent. The opposite of C is 12, and the adjacent is 5, so tan C = 12 / 5

Answer:
y = -1/4x -1
Step-by-step explanation:
Mathematically, we have the slope intercept form as;
y = mx + b
where m is the slope and b is the y-intercept
from the question;
m is -1/4
So we have :
y = -1/4x + b
To get the value of b, we substitute the coordinates given and solve for b
Firstly, multiply through by 4
That will
give ;
4y = -x + 4b
4(-4) = -12 + 4b
-16 = -12 + 4b
-16 + 12 = 4b
4b = -4
b = -4/4
b = -1
So the equation in the slope intercept form is;
y = -1/4x -1

Tom decides to pick up some pizzas and drinks for his family. He notices that the pizza costs the same as 7 drinks. The 2 pizzas and 8 drinks cost $33. What is the price of each item?
Answer:
Drinks = $1.5
Pizza = $10.50
Step-by-step explanation:
let d = drinks
p = pizza
p = 7d equation 1
2p + 8d = 33 equation 2
from equation 1, we know the price of one pizza, the price of two pizzas can be determined by multiplying by 2
2p = 7d x 2 = 14d eqn 3
Substitute for 2p in equation 2
14d + 8d = 33
22d = 33
Divide both sides of the equation by 22
d = $1.5
Substitute for d in equation 1
p = 1.5 x 7 = $10.5

Martha has two pet poodles. Fifi, her standard poodle, weighs 7 times as much as Buttercup, her toy poodle.
Pick the diagram that models the ratio in the story.
If Fifi weighs 56 pounds, how much does Buttercup weigh?
pounds
The diagram that models the ratio in the story is diagram A.
When fifi weighs 56 pounds, Buttercup will weigh 8 pounds.
What is a ratio?It should be noted that ratio demonstrates how many times one number can fit into another number. It contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data points.
Let buttercup be x
Let Fifi be 7x
Fifi weighs 56 pounds. This will be:
7x = 56
7x = 56
Divide
x = 56 / 7
x = 8
Buttercup is 8 pounds.

the new TV was $488, how much was his paycheck?
Please don’t put the answer in a link.
Answer:$175
Step-by-step explanation:
The amount of his paycheck would be $ 784.
What is the solution for an equation?The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of those variable would give a true mathematical statement.
WE have been given that Josh used one hundred dollars less than three-fourths of his paycheck to buy a new N the cost of the new TV was $488.
Let P = pay amount
3/4 P -100 = 488
Now add 100 to both sides of the equation
3/4 P = 588
Then multiply both sides of the equation by 4/3;
P = $ 784
The amount of his paycheck would be $ 784.

Step-by-step explanation:
Step 1: On the horizontal axis, we can choose the scale to be 1 unit = 11 lb.Since the weights in the table start from 65, not from 0, we give a break/kink on the X-axis. Step 2: On the vertical axis, the frequencies are varying from 4 to 10.Thus, we choose the scale to be 1 unit = 2.

There are 336 different ways are there to present those ribbons if the order matters.
What is the combination?A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
Eight students are competing for a blue, red, and yellow ribbon for their agriculture project.
Different ways are there to present those ribbons if the order matters.
By permutations, we have to calculate the number of different ways to arrange the ribbon is;
[tex]=3 \times 2\times 1\\\\=6[/tex]
Now, we have to calculate the different ways to choose 3 winners from 8 is;
[tex]=8\times 7\times 6\\\\=336[/tex]
