Answer:
364
Step-by-step explanation:
25% is the same as 1/4
so if 91 is equal to 1/4 of something
all you have to do is multiply 91 by 4
Answer:
Step-by-step explanation:
My method is multiplying 91 by 4 because 91 x 4 is 364 which if you divide 364 by .25 which is 1/4 in decimal form, you get 91. So the final answer to this 364.

1. Solve the triangle.
AABC, given ZB = 57°, ZC = 720,
and b = 18 m.
Answer:
Angle A= 61°
Step-by-step explanation:
angle A+ Angle B+Angle C= 180°( Angle sum property)
∠A+57+72= 180°
∠A= 180°- 127°= 61°
7. Set up the trig equation with the correct values plugged in that you would use to solve for x. *
sin (29) = 8/x
sin (29) = x/8
cos (29) = x/8
tan (29) = 8/x
Answer and Step-by-step explanation:
To solve for x, we would use the Sine trig function.
[tex]sin(theta) = \frac{opposite"side}{hypotenuse}[/tex]
Plug in the values.
[tex]sin(29) = \frac{x}{8}[/tex] is the answer.

suppose that a data set has an approximately symmetrical distribution, with one outlier. what could you do if you wanted to use the mean and standard deviation to characterize the data?
Answer:
The median is known as a measure of location; that is, it tells us where the data are. As stated in , we do not need to know all the exact values to calculate the median; if we made the smallest value even smaller or the largest value even larger, it would not change the value of the median. Thus the median does not use all the information in the data and so it can be shown to be less efficient than the mean or average, which does use all values of the data. To calculate the mean we add up the observed values and divide by the number of them. The total of the values obtained in Table 1.1 was 22.5
Missing alternative text , which was divided by their number, 15, to give a mean of 1.5. This familiar process isconveniently expressed by the following symbol\

Answer:
X = 16
Step-by-step explanation:
These are supplementary angles, so they equal 180.
5x + 27 + 5x - 7 = 10x + 20
10x + 20 = 180
10x + 20 - 20 = 180 - 20
10x = 160
10x ÷ 10 = 160 ÷ 10
X = 16

17. A line passes through the points (0,5) and (3, 11). Which of the following is the value of y when this line passes through x = 10? (1) 16 (3) 21 (2) 19 (4) 25
Answer:
(4) 25
Step-by-step explanation:
First, find the slope using rise over run:
(y2 - y1) / (x2 - x1)
Plug in the points:
(11 - 5) / (3 - 0)
6 / 3
= 2
The y intercept, (0, 5), has already been given. Using the equation y = mx + b, plug in the slope and y intercept to create the equation:
y = mx + b
y = 2x + 5
Now, plug in 10 as x to find the value of y:
y = 2x + 5
y = 2(10) + 5
y = 20 + 5
y = 25
So, the correct answer is answer choice 4, 25.
The value of the variable 'y' at x = 10 will be 25. Then the correct option is D.
What is the equation of a line passing through two points?Let the equation of the line pass through (x₁, y₁) and (x₂, y₂).
Then the equation of the line is given as,
[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]
A line passes through points (0,5) and (3, 11). Then the equation of the line is given as,
(y - 5) = [(11 - 5) / (3 - 0)](x - 0)
y = 2x + 5
If the value of the variable 'x' is 10, then the value of the variable 'y' is calculated as,
y = 2(10) + 5
y = 20 + 5
y = 25
The value of the variable 'y' at x = 10 will be 25. Then the correct option is D.

Dale just bought 9 bags of 13 cookies each. He already had 6 cookies in a jar. How many cookies does Dale have now?
Answer:
123
Step-by-step explanation:
1 bag = 13 cookies
9 bags x 13 cookies = 117 cookies
117 cookies + 6 cookies that he already has = 123 cookies
Dale have 123 cookies in total.
Answer:
123 cookies.
Step-by-step explanation:
Multiply the amount of bags of cookies he bought, and the amount of cookies in each back to find out the amount of cookies he bought all together.
9 x 13 = 117
He already had six cookies saved. Add that the amount he had bought
117 + 6 = 123
Dale has 123 cookies in total.

In a math class of 35 students, 17 boys and 18 are girls. On a unit test, 8 boys and 12 girls made an A grade. A student is chosen at random from the class. What is the probability of choosing a boy or an A student?
Group of answer choices
0.57
0.71
0.83
0.09
Answer:
.83
Step-by-step explanation:
In order to find the probability that either a boy or an A student is chosen, you must first identify how many boys and A students there are altogether in the class:
9 boys who are not A students + 8 boys who are A students + 12 girls who are A students = 29 students are either boys or A students
Now, you just need to turn this into a probability:
1: 29/35 (given)
2: ≈82.86/100 (multiply both the numerator and denominator by 100/35)
3: ≈83% or .83 (round to the ones place and turn into a decimal)
If gas costs $2.85 per gallon, how many whole gallons of gas could you buy with $30.00?
Answer:
11
Step-by-step explanation:
We can buy 10 gallons of gas with $30, whose unit price is $2.85.
What is unit rate?The rate calculated for one quantity of something is called unit rates.
Given that, the gas costs $2.85 per gallon, we need to find how many whole gallons of gas could you buy with $30.00.
Let the x gallons cost $30.00
Therefore,
2.85x = 30
x = 30 / 2.85
x = 10.52
x ≈ 10
Hence, we can buy 10 gallons of the gas from $30.

To measure the width of a river, you plant a stake on one side of the river, directly across from a boulder.
You then walk 100 meters to the right of the stake and measure a 79° angle between the stake and the
boulder. What is the width w of the river? Round your answer to the nearest meter.
Mattraimale
079
100 m
PUR
m
Answer:
514 m = width of the river to the nearest meter
Step-by-step explanation:
You must memorize the definitions of the trig functions and then these types of problems are easy.
You have a right triangle where the 100 m is the adjacent side to the 79° angle. You are looking for the side opposite the 79° angle. So, you need to use the tan function which is defined as opposite side/adjacent side
Let x = the length of the opposite side (width of river)
Tan 79 = x/100
100 tan 79 = x
x = 514 m = width of the river to the nearest meter
The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. The width of the river is 514.455 meters.
What is Tangent (Tanθ)?The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
Base is the adjacent smaller side of the angle θ.
As it is given that you walk 100 meters to the right of the stake and measure a 79° angle between the stake and the boulder. Therefore, using the tangent angle the width of the river can be written as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}\\\\\\\rm tan(79^o) = \dfrac{\text{Width of the river}}{100\ meter}\\\\\\\text{Width of the river} = tan(79^o) \times 100 = 514.455\ meters[/tex]
Hence, the width of the river is 514.455 meters.

Fred needs 12 meters of ribbon to wrap each gift. He has a spool of ribbon that contains 18 feet of ribbon. One meter is equivalent to approximately 3 feet. How many gifts of same dimension can he wrap using the spool of ribbon
Answer:
5
Step-by-step explanation:
The computation of the gits is shown below;
Given that
The ribbon which is used to wrap the gift = 1.2m
The ribbon that he spoiled = 18feet
based on the above information
As we know that 3feet = 1m
1foot = 1 ÷ 3 m
Now
18feet = 1 ×18 ÷ 3
18 feet = 6m
Now,
