Answer:
The answer is : 0.12 x 600 = 72 or the equivalent : 600 x 12/100 = 72
Your list of possible answers ended up a bit scrambled for me to identify which one it is.
Step-by-step explanation:
The number of black and white pictures can be obtained by multiplying the total number of pictures taken (600) by the decimal form of 12% = 12/100 = 0.12. That is:
Number of B&W pictures = 0.12 x 600 = 72
Pleaseeee help❤️I would appreciate itttt
Answer:
The correct option are;
i) The line segment must connect an _1_ (open) circle at point B to an _1_ (open) circle at point D.
ii) The line segment must connect an _1_ (open) circle at point B to a _2_ (closed) circle at point C
Step-by-step explanation:
The parameters given are;
Domain: [tex]\{x|-4<x\leq 4, x \in R \}[/tex]
Range: [tex]\{y|-4\leq y< 4, y \in R \}[/tex]
Given that to indicate less than (<) on a graph of an inequality, we draw an circle over the point in reference while to indicate less than or equal to (≤) we draw an circle over the point in reference and shade the point, therefore we have;
Given that x > -4, and ≤ 4, the points B and C satisfies the conditions
Given that the y-coordinates are y ≥ -4, and y < 4, the points D and C satisfies the conditions
Where:
Point B = (4, 4) satisfies x only
Point C = (4, -4) satisfies x and y
Point D = (-4, -4) satisfies y only
Therefore, in order to draw a line segment between two points;
i) The line segment must connect an _1_ (open) circle at point B to an _1_ (open) circle at point D.
ii) The line segment must connect an _1_ (open) circle at point B to a _2_ (closed) circle at point C.

Angela is following this recipe to make biscuits.
Angela uses 1.8 l of syrup.
How much margarine is needed in kg?
Recipe: Makes 10 biscuits
150 g margarine
180 g sugar
225 ml syrup
225 g oats
40 g sultanas
Asapppp
Answer : The amount of margarine needed is 1 kg.
Step-by-step explanation :
First we have to convert volume of syrup from mL to L.
Conversion used:
1 L = 1000 mL
or, 1 mL = 0.001 L
So, 225 mL = 0.225 L
Now we have to calculate the amount of margarine needed.
As, 0.225 L of syrup needed 150 g of margarine
So, 1.8 L of syrup needed [tex]\frac{1.5L}{0.225L}\times 150 g=1000g[/tex] of margarine
Amount of margarine needed = 1000 g = 1 kg (1 kg = 1000 g)
Therefore, the amount of margarine needed is 1 kg.

What is
mZ1,
Answer: m∠1=42°
Step-by-step explanation
For this problem, we can separate the triangle into 2 separate triangles to solve for m∠1.
We know that m∠4 is 106°. ∠2 and ∠4 are supplementary angles. You can see that they make a straight line of 180°. We can use this fo find ∠2.
∠2+∠4=180
∠2+106=180
∠2=74°
Now that we know ∠2 is 74°, we can use that to solve for m∠1.
We know that the measures of the angles in a triangle equal to 180°. For the triangle at the bottom, we see ∠3, ∠2, ∠1. Since we know ∠3 and ∠2, we can find ∠1.
∠3+∠2+∠1=180
64+74+∠1=180
138+∠1=180
∠1=42°
Given the function f(x) = -5|x + 1| + 3, for what values of x is f(x) = -12?
Answer:
x = 2 or x = -4
Step-by-step explanation:
-5|x + 1| + 3 = -12
Add -3 to both sides.
-5|x + 1| = -15
Divide 5 into both sides.
|x+1| = 3
Possibility 1:
x + 1=3
x = 2
Possibility 2:
x + 1 = - 3
x = -4
Answer:
Step-by-step explanation:
This is our absolute value equation for which we want the values of x that make it true:
-5 | x + 1 | + 3 = -12. Subtracting 3 from both sides gives us
-5 | x + 1 | = = -15. Divide both sides by -5 to get
| x + 1 | = 3
This says, in words, "how many units from 3 is -1 on a number line?"
We have the following 2 equations:
x + 1 = 3 and x + 1 = -3
Solving the first one for x:
x = 2
Solving the second one for x:
x = -4
Both 2 and -4 are 3 units from -1 on a number line.
I WILL GIVE BRAINLIST enter the correct answer in the box. Write your answer in the form y=mx+b using the appropriate inequality symbol in place of the equal sign
Answer:
y > 4x + 1
Step-by-step explanation:
Look at the graph. The y-intercept is 1, so we have
y = mx + 1
Now let's find the slope.
Go from the intercept 4 units up and 1 unit to the right. You are at point (1, 5) which is a point on the graph.
slope = m = rise/run = 4/1 = 4
The equation of the dashed line is
y = 4x + 1
The shaded area is "above" the line, so the inequality is
y > 4x + 1
Answer:
y > 4x + 1
Step-by-step explanation:
Hope this is right.
A bag contains green yellow and orange marbles the ratio of green marble to yellow marble is 2 : 5 the ratio of yellow arbles to orange marbles is 3 : 4 what is the ratio of green marbles two orange marbles
Answer:
G:O = 3:10
the ratio of green marbles to orange marbles is 3:10
Step-by-step explanation:
Let G, Y and O represent green, yellow and orange marbles respectively.
Given;
the ratio of green marble to yellow marble is 2 : 5
G:Y = 2:5
G/Y = 2/5
the ratio of yellow arbles to orange marbles is 3 : 4
Y:O = 3:4
Y/O = 3/4
the ratio of green marbles to orange marbles G:O;
G/O = G/Y × Y/O
Substituting the values;
G/O = 2/5 × 3/4
G/O = 3/10
G:O = 3:10
the ratio of green marbles to orange marbles is 3:10
If Jake does a job in 15 hours less time than Brianna, and they can do the job together in 10 hours, how long will it take each to do the job alone? It will take Jake ______ hours It will take Brianna _______ hours
Answer:
It will take Jake 0 hours and It will take Brianna 15 hours
Step-by-step explanation:
Let x be the no. of hours taken by Brianna to complete work alone
We are given that Jake does a job in 15 hours less time than Brianna
So,Jake work alone in hours =x-15
We are given that they can do the job together in 10 hours
So, [tex]\frac{1}{x-15}+\frac{1}{x}=\frac{1}{10}\\\frac{x+x-15}{(x-15)x}=\frac{1}{10}\\x=3,15[/tex]
So, Brianna complete work in 15 hours
So, Jake work alone in hours =x-15=15-15=0
So, It will take Jake 0 hours and It will take Brianna 15 hours

which of the following is the solution 4|x+3|≥8
Answer: x≥-1 or x≤-5
Step-by-step explanation:
First, divide both sides by 4 to get rid of the 4:
4|x+3|≥8
|x+3|≥2
Next, we know that for |a|≥b, a≥b or a≤-b. Therefore:
|x+3|≥2
x+3≥2 or x+3≤-2
x≥-1 x≤-5

Lowell has a credit card that uses the adjusted balance method. For the first
10 days of one of his 30-day billing cycles, his balance was $1360. He then
made a purchase for $470, so his balance jumped to $1830, and it remained
that amount for the next 10 days. Lowell then made a payment of $740, so
his balance for the last 10 days of the billing cycle was $1090. If his credit
card's APR is 28%, which of these expressions could be used to calculate the
amount Lowell was charged in interest for the billing cycle?

the graph of F(x), shown below, has the same shape as the graph of G(x)=x^2. but it is shifted up 4 units and to the right 2 units. What is its equation
Answer:
Step-by-step explanation:
The graph of [tex]y=x^2[/tex] in vertex form is [tex]y=(x-h)^2+k[/tex] where h and k, the vertex, is (0, 0). If we shift the parabola right or left, or up or down, the h and k values take on that reflection. If we move up 4, k goes from a value of 0 to a value of 4; if we move right 2 units, h goes from a value of 0 to a value of 2. Putting that together in work (aka vertex) form:
[tex]y=(x-2)^2+4[/tex]
